Firmware is not updated on Android - reasons and what to do. Why can't I flash my phone, smartphone or any other gadget? Why can't the firmware be installed

Updating or installing firmware can eliminate many problems associated with the operation of an Android device. With prolonged use, the system memory of mobile gadgets becomes clogged with residual files () (“casts” of previously downloaded programs), malicious code () and other unnecessary data. All this leads to a decrease in the performance and speed of the processor and RAM. As a result, the smartphone (tablet) often freezes and reboots on its own. And if the factory reset () did not lead to a positive result, the user can only update the software himself. Consider how to reflash a phone running on the Android OS.

Types of firmware and how to install them

Android firmware at home is in many ways different from installing the rest of the software. This process is more time consuming and is associated with many risks. If you choose the wrong version of the software or violate the update process, there is a chance that your phone or tablet will turn into a useless "". However, having learned how much a flashing from professionals costs, many still decide to change the version software on one's own.

For flashing Android, there is no single instruction that would fit all models of mobile devices. It all depends on the manufacturer of the device and what software is planned to be installed.

All Android firmware are divided into two types:

Official. They are supplied directly by smartphone manufacturers and are usually only suitable for a certain brand. Such programs are considered the most reliable, so they should be used whenever possible.
Unofficial (custom). Developed by users of Android devices and small firms. They are applied when Android is reinstalled on Chinese devices (for example, Lenovo, Meizu, Xiaomi, etc.).

When using custom software, there is a possibility of installing a low-quality update, as a result of which the gadget will start to slow down even more. Therefore, you need to download the executable file only after reading its description in detail and reading user reviews.

There are several ways to change the firmware on Android:

Preparing for self-flashing

Before reinstalling the software on an Android device, a number of preparatory measures must be taken:

download a software update program on a PC (Odin, Kies or SP Flash Tool and find a high-quality usb cable (if the reinstallation is done using a computer);
(if you plan to reinstall Android to an unofficial version);
charge the battery of the gadget by 100%;

The functionality of the installed software largely depends on its version and assembly. So that the new firmware does not start to conflict with the hardware after some time, you need to find out serial number mobile device:

We will consider a more detailed procedure for updating Android on a phone using the example of Samsung and Lenovo, although this instruction also suitable for many other brands.

Smartphone firmware from Samsung

Software updates on Samsung devices are performed using the Kies program. This utility allows you not only to reflash a tablet or phone, but also to backup the old system, synchronize personal data with a PC, and much more.

Before upgrading the firmware to the latest software, you need to properly configure Kies. This is done as follows:

After setting up Kies, create a backup of the software available on your smartphone. This will restore the system to working capacity in case of unsuccessful firmware. To do backup android via PC, in the initial window of the application, select " Backup”, mark the items you want to save and start the procedure by pressing the corresponding button.

After creating a backup, feel free to reflash your phone or tablet through a computer. To do this, open the "Tools" section in Kies and activate the item marked in the figure, thereby starting the update process.

While the device is being flashed, in no case disconnect it from the PC and do not perform other actions that may lead to a disconnection.

After flashing the Android phone through a computer, check the performance of all its functions. If nothing fails, then the software update was successful.

Replacing the firmware on a Lenovo tablet via a PC

Before flashing a Lenovo tablet, you need to understand that there is no software developed specifically for this brand. Therefore, one has to be content with universal developments. One such application is the SP Flash Tool. Consider how to update the software on Lenovo using this utility:

After you managed to update the firmware, check the performance of all tablet functions.

The Android operating system is very stable, but in some cases, problems may arise with it. They are usually associated with the work of the current firmware. There are many ways to flash; in this article, we will look at how to flash Android through Recovery.

There are several basic ways to enter this mode:

How to get ROOT rights: Video

Firmware with ROOT access

Let's figure out how to install the firmware through it. First of all, you need to find and download as an archive new version firmware.

The gadget will reboot and 8 items will appear in front of the user. Each of them is responsible for a specific operation. For example, if you go to "Wipe / factory reset"- the system will be reset to factory settings (in some cases, simply by activating this item, you can avoid the need to change the firmware when the device does not work correctly). "Install" makes it possible to install files when it is impossible to do this from the shell itself.

For the firmware, you need to go to the “Install” section (it is located in the extreme left corner), select the place where the firmware was downloaded, and start the process.

After a while, the system will report a successful completion, then you will need to exit the “Install” mode and select the “Reboot” mode. There, click on the "System" item: if the whole operation was carried out correctly, the device will boot successfully.

Flashing Recovery Mode

Now consider the question of how to flash Recovery on Android. To do this, you need to install the so-called CWM Recovery. The easiest way to do this is with special utility, which can be found all in the same Google Play store at this link. In this case, superuser rights are also required. Having launched the program, you only need to follow its instructions by clicking "Next". If CWM Recovery is already installed on the system, then the utility will simply ask you to select the appropriate item that performs an action related to firmware or reset to factory settings.

Any device with Android OS starts in Recovery mode. This is a standard feature. However, with the factory option, you can perform too narrow a range of tasks. So, this is resetting the phone to the initial settings, clearing the cache, as well as updating the system from the update.zip file. Obviously, users who are expanding their knowledge in the IT field are very unhappy with such a meager list. This is where specially developed Recovery Modes come to the rescue. CWM Recovery is a popular tool among Android users and a worthy factory replacement.

Why do I need CWM Recovery mode

Clockworkmod Recovery (CWM) is a famous factory recovery alternative developed by Koushik Dutta. You can install it on most Android devices. CWM Recovery helps even in situations that sometimes seem hopeless to an ordinary owner. That is why it is necessary to know about its existence, as well as be able to use it.

CWM mode has many options

What exactly does the utility do:

Installs unofficial custom firmware and kernels.
Installs factory system updates, OS additions and patches.
Connects to a computer via USB in removable storage mode and to work with the ADB program.
Creates a full backup of the current firmware and its individual parts (system, settings, applications).
Restores a device from a previously created backup.
Resets to factory settings (Wipe - data / factory reset), clears the cache (wipe cache), clears the dalvik cache (wipe Dalvik-cache), clears battery statistics (wipe battery stats).
Creates partitions on the memory card and formats them.

CWM: installation instructions

ClockworkMod is sewn into the internal memory of the device in place of the factory mode. In some cases, work is carried out on the gadget itself with access to Root-right, and in others - on a PC.

The article covers such basic methods as Rom Manager, FastBoot, Rashr and Odin. For many devices, the companies themselves release separate utilities, for example, Acer Recovery Installer for Acer devices. CWM is embedded in the device memory on these devices also through the ADB software, which is suitable for devices with the HTC manufacturer.

Rom Manager: Root rights and sewing

Rom Manager is a utility created by CWM developers. It is available for download on the Google Play Market. Allows you to install CWM Recovery on the device itself without using a computer and a USB cable. Before using it, you need to root the device, that is, get administrator rights.

Getting Root Rights

The procedure is straightforward and is easily carried out using special software. Take Framaroot as an example. With its simple and intuitive interface, everyone can handle it even without instructions.

Launch Rom Manager

Now is the time to use the program:

Video: how to flash Recovery with Rom Manager

Although the method is easy, there is a drawback in it: it is not suitable for all devices, as already indicated earlier. Before you start using this method, it would be logical to first determine that this program is compatible with the gadget. The list is available on the official Rom Manager website.

FastBoot Mode: The Complicated Method

The method of installing CWM using FastBoot will require skill from the user, as it is much more complicated than the previous one. It does not run on the device, but on the computer. It is recommended to use it only if you already have skills in such operations. Before the installation itself, you need to download certain files to your computer or laptop. This list also includes the Android SDK platform available for Windows, Mac and Linux.

Preparatory stage

What to have before installing CWM using Fastboot mode:

Windows computer and USB cable to connect the device to the PC.
USB drivers for correct device detection. They can be downloaded from the official website of the manufacturer.
Android SDK platform.
recovery file.

The Android SDK utility will help you install the required Android SDK Tools and Android SDK Platform tools:

What else needs to be done before starting the firmware itself? Judging by the list above, you need a recovery-clockwork.img file. This is one of the key tools for further work. Downloading it is not difficult, but this is not the end of the matter. It is important to place this file in the platform-tools folder. For further convenience in the firmware, you need to rename it to recovery.img.

Place the file in the platform-tools folder

Straight to the point!

Now everything is ready for the CWM firmware itself, so you can safely get to work. Below is a detailed description of the actions in which it is quite difficult to get lost.

The level of complexity, as you can see, is high, so before the procedure it is strongly recommended to check that this method is suitable for the device, since it may not work in all gadgets. In practice, this method is good if the manufacturer of the device is HTC.

Rashr application

The installation method using Rashr is convenient and easy to perform, it is recommended for beginners. However, ironically, it also requires administrator rights. You can get them in a few steps. was given earlier in the Rom Manager section.

How to work with Rashr

First you need to download the application itself. It is located in free access v Play market(Rashr - Flash Tool). You can also watch the program on a third-party site, but you must beware of suspicious web pages so as not to catch a virus.

When the program is already on the phone, you need to open it and provide it with previously received Root rights upon request. Further, everything is simple:

Video: CWM and Rashr

Odin: solution for Samsung

The previous three methods are suitable for different models devices. The same method is effective for Samsung devices. This is a proprietary utility, so it cannot be used for devices from other manufacturers. There are many versions of this application. The last one is Odin 3.09.

Here, the standard factory version of Recovery is changed to a modified one using a PC, as with FastBoot:

How to enable CWM Recovery mode after flashing

After the CWM mode has been set using one of the above methods, you need to check if it works. You can launch ClockworkMod Recovery:

using the ROM Manager program, selecting the section on its home page " Download Recovery mode";
by pressing the keys simultaneously after turning off the device. Combinations may differ depending on the model and manufacturer of the device. In most cases, these are the volume down and power buttons;
using the ADB program using the adb reboot recovery button.

Possible difficulties

During the installation of an alternative Recovery Mode, in particular, CWM, various difficulties and errors may occur. Which of them are the most common and how to solve them?

CWM Recovery does not recognize the memory card

CWM makes it possible to update the phone using the archive. When opening Recovery, the user sees a message that the flash card cannot be mounted. After installing another card, even with less memory, the problem disappears. The reason lies in the Windows system itself. The fact is that it diverges from the standards for formatting the card. In order to format according to the specifications of SD/SDHC/SDXC flash cards, and not just in the standard form, it is recommended to use specialized software, such as SD Formatter.

The SD Formatter program allows you to correctly format the SD card

CWM does not see the internal memory of the device: a solution to the problem

When the files to be recovered are on the internal storage, and therefore can only be recovered from there, a problem may arise. When connected USB cable to the PC and turning on USB debugging, the program reports that the Android device is not detected and you need to turn on USB debugging.

To solve this problem:

Connect the device as a camera, not a storage device. If there are other options available, select them.
Install generic drivers.
Find a more suitable Recovery program for the device.

Recovery menu not working

If, when starting an alternative recovery mode (volume + Home button or power), a picture appears with a lying robot, then the recovery was flashed, but when the device was restarted, it was overwritten by the stock Recovery.

The problem is solved in the following way.

Before flashing with Odin3, you need to remove the Auto restart checkbox and disconnect the cable after flashing. From the Download mode on the device, switch to the recovery mode by holding the volume up + home screen + power keys in sequence, and hold them until the recovery menu appears. So in any case you should get into the custom recovery menu.
In it, select Reboot system now and then mark Yes. This action will overwrite the stock recovery with the custom one and the "No command" error will be fixed.

Flash a new one recovery mode- means to acquire new functionality. The firmware methods differ in their complexity, but ironically, the simplest of them require Root access, that is, device administrator rights. When choosing a firmware method, you need to be guided by the phone model in the first place. Rom Manager is not suitable for all devices. For HTC, the FastBoot method is more suitable, and for Samsung it would be more correct to choose Odin.

What to do if a smartphone based on the Android operating system suddenly starts to freeze and behave as if it has a life of its own? How to flash a device based on the Android operating system?

Many users of modern gadgets of well-known brands are tormented by this issue: from top-end devices from Samsung or Sony to the popular Xiaomi and Meise.

Possible ways to solve problems

"Recovery": what it is and what it is eaten with

Many users immediately give up and rush to contact service centers. However, any experienced user knows that this is not necessary. After all, you can save a decent amount of money and nerves by following just a few simple steps given in this manual. "Recovery" is a special software that is available in smartphones based on the operating Android systems. It is something like the BIOS on a regular personal computer. That is, with the help of "Recovery" you can completely reset the smartphone to factory settings. Here you can also flash the device or install operating system updates. Upon purchase, the user most often receives a device with a factory Recovery menu. It is slightly limited in functionality and does not allow you to successfully flash the operating system. If we talk about the "custom" "Recovery", then it allows you to more fully interact with the phone system. Thus, you can make backup copies of firmware and restore them, as well as carry out a deeper and more complete reset of the device.

"Recovery": how to enter

To flash the device through the "Recovery" menu, you need to get into this very menu. This can be done quite simply, especially considering that many devices use the same login combination. So, if the smartphone has a “Home” button or a physical central button, then on the turned-on gadget, simultaneously press the “Volume +” and “Home” buttons. After that, without releasing these buttons, you need to press the power button. The device should turn on desired mode. In the event that the user has a more modern device without a physical Home button, it will be necessary to repeat the process that was described above, but only when using the Volume + buttons and the power button. If the desired result is not achieved, it is recommended to refer to the extended list of ways to enter the Recovery menu for devices from various manufacturers.

What else is needed?

To understand how you can reflash an Android device, you must first download the firmware for your device. Firmware files are most often hidden from public view in order to preserve the manufacturer's data and security. It is for this reason that ordinary users create backup copies of their OS and form databases of stock firmware from them, links to which can be found on special sites. It is the firmware file itself, which is in the archive with the * .zip extension, that will be needed in order to learn about restoring "Android" through "Recovery". Sometimes there are times when the old firmware bothers users and they want something new. It is for this reason that there are always craftsmen who develop custom firmware, adding something new from them or, on the contrary, “cutting out” the excess. In this case, the standard "Recovery" will not work. This is where custom CWM Recovery or TWRP come to the rescue.

How to install CWM Recovery or TWRP

It is not necessary to install "Recovery" on Android using a personal computer. Most often it is easier to use stock. All you need to do for this is to download the necessary file, which is in the *zip archive and move it to the smartphone's external flash card. After that, you need to go to the stock "Recovery" and select the item "Apply update external storage" there. In the list that opens, you must select the same file with custom "Recovery". When the selection is confirmed, the installation process will begin. The device will then prompt you to reboot. The process will be completed.

How to flash Android through "Recovery"

Let's proceed directly to the process of installing the firmware. I would like to note that all unofficial Android OS files created directly by users are installed only at their own peril and risk. If the decision to install non-native software is nevertheless made, you need to make sure that the firmware was written specifically for the smartphone model that you plan to reflash. If it's about stock firmware, then it's better not to bother installing CWM Recovery or TWRP. All manipulations that should be done are limited only to downloading the factory file and moving it to an external memory card. The process after that will be similar to installing a custom "Recovery". You need to go to the stock menu "Recovery" and select the item "Apply update from external storage" in it. Then you need to specify the firmware file and confirm the action. When the process is completed, you will need to perform one more step, which will avoid "glitches" and freezes when you turn on and operate your smartphone. Immediately after the firmware is installed, you must select the menu item "Wipe data / factory reset" and confirm the operation. Thus, you can clear information about the previous software, as well as about those files that were on the device before the firmware process. When all these actions are completed, you will need to select the "Reboot system now" menu item. The device will reboot and the smartphone setup process will start from scratch. In the event that the power-on process is delayed and the device logo “freezes”, it will be necessary to remember whether the reset item was completed after flashing.

Custom versions of Android

How to flash Android through "Recovery"? It remains only to figure out what to do with versions of operating systems that were written directly by device users. The answer to this question is quite simple: you need to repeat the whole process, performing the same manipulations in custom Recovery. The only difference is that the firmware file itself can now be placed not only on an external memory card, but also in the internal memory of the gadget. This will add convenience to the user in the event that a flash card is not available. Then you have to select the item "Apply update internal storage". It is also worth noting that in TWRP and CWM Recovery, the “Wipe data / factory reset” item has been replaced with two separate items “Wipe cache” and “Wipe data”. After you manage to install Android through "Recovery", you will need to select the "Wipe Dalvik cache" item in the modified TeamWin or ClockWorkMod menu. This will significantly increase the chances of successfully shutting down the device with the new OS.

How to restore stock firmware?

If the user does not like the new custom firmware, there is always the opportunity to return everything to its place. Many today are interested in the question: how to restore Android through Recovery, namely through the stock version? The answer is hidden in the paragraph above. Returning everything to its place occurs in the same way as the implementation of the initial changes. All you need to do is download the firmware from the manufacturer to the internal memory or flash card, and then select the appropriate item in the "Recovery" menu and perform a full reset. In principle, there is nothing complicated in this.

There is really nothing complicated in the firmware of a smartphone based on the Android operating system. But if you are not sure about own forces, then it is better not to mess with these processes. If, nevertheless, something does not work out, then you can always restore the device firmware using the corresponding menu item. The main thing is to make a backup before flashing Android through Recovery. To do this, you need a custom "Recovery" and a little patience. The process of restoring the firmware takes a lot of time. If something does not work out, you can always turn to specialists for help.

If after flashing the Android operating system there are problems in the operation of the device, you need to understand the situation and find the reasons. Very often, users, due to their inexperience, use pirated firmware, which do not allow for high-quality firmware. In this case, you are left for a long time without a reliable assistant - your smartphone or tablet.

Many users who have already encountered the problem of low-quality Android firmware have tried the method of flashing the Android OS through recovery. This firmware method involves pre-installing on a mobile device special program, which acts as a loader. Recovery is activated by clicking until a certain key combination is loaded (power button + volume button).

If the user has chosen this method, he must find out. Regardless of the device, it comes with its own factory recovery. It can be launched after turning on the device. Also, the factory program can install and configure system updates from update. zip and clean up the entire system.

To flash the phone through recovery, you need to find and download the ClockworkMod Recovery program (installed in the internal memory of the device, in place of the factory version). It is intended: for flashing Android and the kernel, creating backups for system recovery, for other system updates. This utility is significantly different from the factory counterpart.

If the user is interested in how to flash an android through the recovery menu, this issue must be considered. Custom Recovery Menu is a special application that has a package of popular utilities. After installing the application on the device, it will overwrite the old version of the similar application.

Custom Recovery Menu is necessary for users who plan to flash the device very often.

Android firmware through the Custom Recovery Menu is very simple. It can be done using a PC or laptop. To do this, go to program activation and select the appropriate firmware items.

Entering recovery mode.

Turn on the phone (Power button);

After 2 s. press the volume button in both directions at the same time;

After another 2 s. release the power button;

We carry out the Wipe process (Wipe data / factory reset);

After the process, Data wipe complete appears;

We reboot the device and go into recovery again;

Choose One Of The Items (install zip from sdcard, choose zip from internal sdcard). It depends on where the firmware is;

If everything is entered correctly, the firmware starts.

At the end of the phone firmware process, you need to reboot the device and start using it.

By default, all Android devices have a recovery mode called Recovery. With it, you can roll back the operating system to standard settings, install official add-ons and fixes. If this is not enough for you and you want to install third-party firmware, kernels and utilities on your device, then you need to replace the factory recovery with a custom one.

Custom recovery: what to choose

The most popular custom recovery for Android are Clockworkmod Recovery (CMD) and TeamWin Recovery (TWRP). The main difference between one program and another is the presence touch control in the last one. As for the functionality, the software offers approximately the same list of options:

Installation of unofficial patches, firmware;
Connecting the device to a PC in ADB mode and instead of a removable drive;
Formatting, creating, merging partitions in the internal memory of the device;
Clearing the software cache and battery summary;
Creation of backup copies of the system.

After studying the methods below, you can easily install custom recovery on Android. You need to get Root-rights before carrying out work.

Ways to install TWRP

You can install TWRP recovery using a special software developer utility (TWRP Manager), third-party software designed for flashing recovery, and Android Debug Bridge (ADB).

Installing TWRP using TWRP Manager

Your first step is to download TWRP Manager from the Play Store and install the application on your device. The utility must be opened to give rights to Root access. Then:

in the menu that appears on the left, select "install twrp";
a window will appear in front of you where you need to select the device and the version of the recovery that you want to install;
after selecting all the settings, click “install recovery”;
program in automatic mode download the recovery and install it;
if you want to install a specific version of recovery that you downloaded in advance, then you need to save recovery.img and select it through the “select img file” item.

ADB as a way to flash recovery

Such a solution with reinstalling the recovery is suitable for advanced PC users. To carry out the manipulations, you will need an Android device, a computer and a USB adapter. First you will need to install the Android SDK with all packages along with the Google USB Driver. Thereafter:

save the Recovery.img version of TWRP supported by your smartphone to your computer;
rename the recovery file to twrp.img, save it to the root memory of your device.

Connect your device to your computer with via USB. Launch the PC operating system command line (cmd in Windows). Write the following lines in it:

cd C:\android-sdk-windows\platform-tools\adb;
su
dd if=/sdcard/twrp.img of=/dev/block/mmcblk0p34.

After that, reboot your device.

Ways to install CMD

You can install CMD using Rom Manager, FastBoot mode, or third-party utilities for flashing recovery.

Installing CMD using Rom Manager

Download Rom Manager from the Play Store and install it on your device. Don't forget to give it Root access.
After starting the program, a window will appear, including several sub-items. You will need to go to the "Recovery Setup" tab.
A new window will appear. There select CMD. After that, you will need to select the model of the device on which the recovery will be installed.
After that, another window will appear where you must confirm your actions.

Rom Manager will download the files to install the recovery, ask for Root rights if you did not provide them by default. After that, she will proceed to install the software. Once everything is finished, you can check the installation of CMD by going from the main menu to the "Reboot into Recovery" tab.

CMD installations in FastBoot mode

To reflash an Android device in this way, you will again need to download the Android SDK, a USB driver for your smartphone / tablet. Save the recovery file from the CMD website, rename it to update.img, save it to the platform-tools folder located in the directory of the installed Android SDK. Then enable USB debugging on your Android device.

Launch Command Prompt and enter the following commands:

If everything goes well, a corresponding notification will appear on the command line.

Installing CMD and TWRP via Flashify

As we mentioned earlier, install custom recovery for Android third party utilities. One of them is Flashify. A distinctive feature of the program is compatibility with many models of smartphones and tablets. You need to install the software on the device and allow it to use Root rights.

On the main screen of the running application, select "Recovery Image".
You will see a window with a choice of recovery version and a choice of device model (if you have not downloaded the program in advance).
After the desired version of the recovery is saved to the device's memory, click on "YUP!".
Flashify will install the program, automatically reboot the device.

This post (manual or mini FAQ) is intended for people who have difficulty flashing or updating the software of their electronic device. All typical errors that prevent you from flashing your phone will be highlighted here.

To be honest, for all the time I have been working as an engineer, I have seen quite a few such problems. I can’t remember everything right away, but I’ll show you the bulk of these jambs that do not allow you to flash the device. And so this manual will be replenished and grow over time.

You can also write your problems with the firmware in the comments - this is only welcome. Before proceeding with the firmware, software update, rooting or other actions that can kill the device, observe the following rules.

1. Mindfulness and "straight hands"

Almost every day I have to fix other people's jambs that led to the inoperability of the device, due to the user's fault - he just wanted to update the firmware on his phone, but he never did it and pressed any button in the process, or read the instructions inattentively by firmware, or chose the wrong version of the software - turned your favorite gadget into a "brick" - a useless piece of plastic, glass and metal.

Learn from others' mistakes. This means before pressing the START or DOWNLOAD button (there are others), find a workable scheme for updating software, firmware, rooting, installing any other software. Do everything strictly according to the manual and do not change the settings of the flash driver if you do not know what this can lead to. Just be careful.

2. Bad battery

Due to a faulty or discharged battery, the device may not flash completely or even not even start the process itself. Such cases are also not rare. Fly IQ4404 Spark with its clumsy battery immediately comes to mind. I fully charged this battery and put the device on the firmware and after a few moments (in different ways) when loading files, an error occurs and the process stops. And now we have a "brick". But this fly is not afraid of such zigzags of fate, it is enough to restart the firmware.

I start over (the battery is fully charged, according to the phone indicator) and after a minute the error again. Well, I think the “flash drive” has died and I’m already starting to get upset, but I don’t give up. I put it on for the third time to flash it, but without this battery, and I hook up the power supply. The device was flashed. You can object to me and say that this is some kind of accident, but this is a fact.

I had more than one or even ten of them. But in fairness, I will say that this is a special case and in 99 percent of the devices are flashed normally if the battery is charged. There is a technique that can be flashed without a battery at all. But it's better not to risk it - do not be too lazy to charge the battery.

3. Problems with software

It happens that the device does not want to flash due to the software installed on the computer or laptop. Everything is individual here, but the same thing has a place to be.

For example, there are phone models that are “sewn” only on WINDOWS XP PROFESSIONAL SP3, but on the seven they are no longer detected or the flash driver is stupidly not installed, giving an error. Also if in operating system not installed necessary components, the drivers were installed normally, but the smartphone was no longer detected in the system.

I had such nonsense because of the truncated Windows - WINDOWS XP HOME EDITION. I had to manually install everything, and this is still that hemorrhagic. Here are a few more reasons that will lead to errors - broken archives of firmware and flashers, incompatible software versions with hardware - it happens that several different revisions are released for a certain phone model motherboards, on which processor and memory chips from different manufacturers are installed, because of this, there are several firmware, not correctly installed drivers, lack of administrator rights in the system.

If the firmware is not correct, the boot (boot area) may fly off and the device will stop showing signs of life at all - in 90 percent of cases you will have to contact the service center, where there is a special programmer. So be very careful, double-check everything several times.

4. Hardware problems

If your device freezes, shuts itself off, does not turn on, or its battery quickly discharges during operation, then this is not a fact that these problems will disappear when updating the software or resetting the settings. Here, most likely, everything is much sadder, namely, this is due to the hardware of the gadget.

Here are a few typical jambs due to which the phone may not be flashed - the system connector is damaged or dirty, the cable for the firmware is damaged or it is not quite original, the USB or COM connectors of the computer are faulty, the liquid inside the device, problems with the power circuit, etc. This may be a huge variety of reasons. In this case, contact the service center for diagnostics.

Make sure before flashing:

1. Charge the battery fully.
2. Visually check for mechanical damage, contamination of the PC and phone connectors. If there is, it needs to be corrected.
3. Make sure that the firmware cable is original and in good condition.
4. Check for viruses and integrity of all downloaded firmware, flashers, drivers, etc.
5. Also make sure that you have correctly installed the drivers, flasher and other necessary software components.
6. Strictly follow the instructions when updating the software.

If you follow these simple rules, you will have much less trouble during the software update process. Write in the comments your jambs with firmware. Let's fix them together. Good luck.

A fairly common problem that many users of Samsung smartphones and tablets encounter is that custom Recovery is not installed after flashing in Odin!

There are two types of this problem:

During firmware custom recovery In Odin, the message ".... /failed 1)";

This article aims to solve common mistakes and learn how to avoid them in the future.

Problem Solving (succeed 0/failed 1)

This problem can occur not only with the Recovery firmware, but also when changing the firmware to a new one or the firmware of other partitions.

Why does given error and how to solve it:
1. The image of the downloaded recovery is not completely downloaded, or it is broken - download the custom recovery file again or download from another site.

2. MD5 amount does not match - note that at the end of the recovery file there is an MD5 extension, it serves to verify that the file is whole / broken, but if you change at least one letter in the file name, then recovery will be considered broken. If you are sure that the recovery is not broken, then remove the MD5 extension at the end of the file. 3. COM port error - make sure that the MicroUSB cable is intact, without damage, the plugs are not bent. On the computer, use only those USBs that are directly located on motherboard, do not use USB hubs.
4. Error with drivers - update Samsung drivers, update USB drivers motherboard.

5. Reboot your device every time new firmware- if the firmware was successful or not successful, reboot the device otherwise the next firmware in Odin will cause an error (succeed 0/failed 1).

6. Make sure that the file being flashed is for your Samsung - if you start flashing someone else's file not from your Samsung smartphone or tablet, you can at least get an error (succeed 0/failed 1), and at most break the device.
