Android tablet firmware without a computer. How to reflash an Android tablet: methods and step-by-step instructions What does it mean to reflash a tablet

Despite the fact that Android devices are significantly different from a regular PC, they also require regular updates and reinstallation of the operating system. This is required to optimize and improve the performance of gadgets. But in some cases, the OS starts to "slow down" or does not work adequately. It is often not possible to solve such a problem with a normal reset - here you need to completely reinstall everything. There are special programs and methods for this. Let's talk today about how to reflash an Android tablet and what is required for this.

Types of firmware

Today there are two types of firmware: official and unofficial. The latter in the language of the inhabitants is also called custom. Official firmware have significantly lower performance and at the same time, unlike unofficial ones, are more stable. This is where the user has to make a difficult choice. But do not think that custom firmware is worse than the official ones, because they are productive and more saturated. useful features. So before you reflash the tablet, it is recommended to study the innovations in more detail.

Regardless of which firmware is used, to install it, you must use special software. At the same time, it can be installed both on the tablet itself and on a PC, which will later manage the reinstallation.

Flashing methods

In order to reflash an Android tablet, you can use several methods. The simplest among them are:

firmware using Wi-Fi;
firmware using a PC;
firmware using a flash drive (self-installation).

Each of these methods has its pros and cons, which must be taken into account when flashing your tablet. So, let's take a closer look at everything that will allow you to freely install high-quality software on your gadget in the future.

Firmware using Wi-Fi

This method is also popularly referred to as FOTA (OTA). Flashing using wireless communication is the simplest. In this case, you just need to agree with the offer, and the OS will install itself on the tablet. AT this method there are also many disadvantages. One of the most important is the ability to install only official firmware versions.

To activate automatic update Android OS, you need to go to the "Settings" menu. Next, find the sub-item "All about the device" and in front of the "Software update" field, check the box that activates the function. If you decide to control the update yourself, then the checkbox must be unchecked.

Unfortunately, it is almost impossible to reflash a Chinese Android tablet in this way. The fact is that the manufacturers of this country focus on the release of new products, and do not carry out maintenance of existing ones. It is in this case that you need to resort to the following method - installing the OS from a PC.

Flashing using a PC

This method is perfect for those who want to install custom firmware. First you need to install special software on your PC. As such, they can be used as official programs from gadget manufacturers (practiced by Samsung, LG, etc.), and unofficial ones (created as a third-party product, but no less effective). For those who are thinking about how to reflash a tablet on Android, this option will be the most acceptable. Additionally, it is suitable for those cases when the gadget does not have a slot for a USB flash drive.

After installing the program, regardless of which of all types you have chosen, the tablet will automatically synchronize with the program and find firmware versions. Then you just need to agree to the terms and accept them.

There are also options that require firmware on the computer. In this case, the tablet must be disconnected and connected to the PC when USB help- cable. Next, the program itself detects the gadget and offers to choose the location of the firmware. After specifying the address, you can agree with the flashing. This is how the Flash Tool works, for example.

Flashing using a flash drive

If your gadget supports memory expansion, and you are thinking about how to reflash the tablet, then this can be done using a flash drive. The method is simple and does not require much effort.

First you need to download the desired firmware version to your computer. It can be both official and custom. Next, you need to download the firmware to a USB flash drive and insert it into the tablet. After such simple procedures, just hold down the "Home" (Home) and off buttons. If the first is touch, then instead hold the volume rocker up. Hold until a green robot appears on the screen - the Android OS logo. Everything, the installation went. Now the main thing is to control that the battery does not sit down. If this happens, then there is a high probability of the final "death" of the tablet without the possibility of recovery.

Things to remember when flashing a tablet

Having figured out how to reflash an Android tablet on your own, you must definitely learn about a kind of safety precautions - installation rules. If you do not follow them, then there is a high probability of losing not only all your data, but also the device itself.

The very first thing that is recommended to do before flashing is to make a copy of the old one. Here you can go for a trick: before Android, you need to install the ROM Manager program. This utility will allow you to install a new OS and at the same time save the logs of the old one. If something went wrong during installation, you can rollback at any time.

Make sure the battery is at least 70% charged. This will ensure that the installation process proceeds normally and the tablet continues to work.

Before flashing an Android tablet, make sure that the firmware itself is designed specifically for your gadget. If nothing works after reinstallation, and the device does not show signs of life, then select new assemblies.

Android is an open source system. Developers can modify the software, add new features, and create their own images. Any user can install third-party firmware on their device. Today we will tell you how to reflash a tablet on Android.

Self-reflash the tablet to Android based or even install Linux (and other third party system) through software updates, recovery menu or TWRP Recovery, via computer and USB cable.

The most common reason for flashing is a decrease in device performance (i.e., the tablet freezes, is buggy, sometimes the procedure is required after repair and installation of new hardware modules).

TOP 5 reasons to reinstall the system:

Get the latest OS version, with updated security packages. Some manufacturers are ending post-sales product support. As a result, the user cannot update the system automatically.
Refusal of branded shells. Poor-quality noname-brand firmware slows down the system. Pure Android shows record speed and returns the standard settings.
Removal of pre-installed software and / or viruses. Flashing will allow you to get rid of unnecessary software that aggravates the system, and the user can install Yandex or Yula on his own.
Gaining access to engineering settings and additional features. Firmware AOKR, Chinese Lewa and Oppo are based on stock Android, but greatly expand the possibilities of customization.
Safety. Free software may be safer than a product from Google. In user software, you can enable parental control or other options for data protection.

In some cases, for a tablet (if it does not turn on, slows down or does not charge, although there are no problems with the memory and port), flashing is the only way to bring the device back to life.

Risks

There are problems that you may encounter when experimenting with software updates:

the flashing process is quite simple, but with some degree of bad luck and inexperience, you can turn the device into an unnecessary brick with microcircuits;
custom firmware may not be optimized for the device, it will quickly discharge the battery or disrupt the operation of the navigator, blocking the signal from satellites;
new software can only partially support the technical part of the device, the result is errors and non-working modules;
after flashing, the user loses the warranty.

It is worth updating the software yourself if you are ready to take risks. Without understanding the operation of the software and minimal technical skills, in the absence of a desire to study the topic, it is better to entrust the flashing to a specialist.

Device preparation

Before updating the system, the battery of the device must be fully charged. If a laptop or PC is used for flashing, you should take care of an uninterruptible power supply.

Losing power while reinstalling software can be as disastrous as damaging the BIOS on a computer.

Remove sim and memory card

Creating a backup

Installation new Android will lead to complete cleaning systems, so you first need to create backup and save all data to external media.

You can save data to Google account or any third party media. Synchronization with Google is the easiest way. Enabled in device settings. You need to select a working account and click "Synchronize". When you sign in to your account from a new device, all data will be restored automatically.

The procedure for creating a backup is as simple as possible:

Turn off the device.
Turn on by holding the volume up and unlock key. Sometimes you additionally need to press "Home". The exact combination depends on the tablet model.
Use the volume buttons to select " backup and restore" and confirm with the power button.
Wait for the backup to be created (it will take 5-10 minutes) and select "reboot now".

If there is no such item, you can backup the system using third party programs. You need to install Titanium Backup (download from Play market), run the utility and grant root privileges, then select Back Up User Software and System Data.

Other feature rich apps that you can use to create a backup:

ROM manager. Manager with large quantity settings, which provides convenient work with ROM-files.
SP FlashTools. Professional Program supports Chinese models of phones and tablets with MediaTek processor.
Helium (previous name - Carbon). A simple solution with convincing functionality. The set of copy functions is limited, but root rights are not required.

Firmware via computer

Through a PC or laptop with Windows OS, you can update the software of a tablet that does not turn on. Most convenient way– download special program. You can install the new version from the official website of the device manufacturer. Or by downloading from w3bsit3-dns.com specifically for your model.

Instruction:

Download the utility and install it on a PC.
Connect the tablet via a USB cable and select the "Software" mode. Some devices require a reboot afterwards.
It will search for updates in auto mode. If there are any, a window will appear with the “Start Update” button active.

You can also update the firmware via a PC using third-party programs (the description of the best is given below).

Necessary:

Install software that will update the device software.
Install the latest drivers on your PC.
Download the update file on the Android developer forums w3bsit3-dns.com (site in Russian) or xpda (English).
Unzip the update to the correct directory. For example, when using FlashTool, unpacking to a folder with the program is recommended.
Run and add firmware files. Scatter is always added first, which generates a list of other software update files. In the Flash Tool, adding is done by clicking on Scatter-loading.
Connect the device to the computer via USB and start downloading (Download). The update starts, after which you need to disconnect the tablet or smartphone from the PC and reboot.

FROM different models devices, software and software versions, the update procedure is approximately the same. This means that after flashing, for example, Explay SM2 3g, it will be possible to reinstall the system on any other tablet without any problems.

Ask a question to a virtual expert

If you still have questions, ask them to the virtual expert, the bot will help you find the problem and tell you what to do. You can talk with him about life or just chat, it will be interesting and informative!

Type a question in the field and press Enter or Submit.

Installing updates via wi-fi

After the release, the OS update is not immediately available.

If after the release of the official update the system does not reinstall automatically, you need to do the following:

Erase app data to free up space so the update installs faster.
Connect to WiFi.
Go to "Settings", select "About tablet".
Select "System update" - "Check for updates".

So only official updates are installed, but not custom ones.

Via OTG adapter

All modern tablets (Ritmix RMD, Irbis tz877, etc.) support USB OTG technology. So, using an adapter, you can reflash a tablet without an SD memory card slot. The flash drive with the firmware must be formatted in file system FAT32.

An AF-micro AM adapter is used for connection. A flash drive is connected to the first, a tablet is connected to the second. Further actions are the same as in the case of reinstalling the OS via an SD card.

Update with third party recovery

Every Android device including tablet samsung galaxy Tab 2 or Honor 8 smartphone has a "recovery mode". But third-party software has more features and is much more convenient to use.

CWM Recovery

latest version(6.0.5.3) is available in standard version and improved version with touch control. In the first case, the control is carried out with the volume buttons, and in the second - with the help of touches. Modifications differ only in power consumption, the functions of the utilities are the same.

You can install CWM Recovery using special utilities(Galaxy Nexus, ROM Manager) or from the command line.

In the Galaxy Nexus Toolkit, this is done like this:

Select the tablet model and firmware.
Turn off the device and enter Fastboot mode by holding down the volume and power keys.
Connect to PC.
Press 6 in the Galaxy Nexus Toolkit (this is the item " Flash Recovery").
Select CWM.

You can run CWM from the OS using the ROM Manager or through the Recovery item in fastboot mode.

TWRP Recovery

You can download the recovery from the Internet - there is an official TeamWIN page on the network.

So the software is installed on Samsung:

Disable OEM lock on 2015 and newer tablets.
Download Odin.
Go to Download mode and select Twrp Recovery.
Connect your tablet and start updating.

TWRP is installed on any device only through third-party ADB and Fastboot, the official Official Twrp App, Rashr utilities, Twrp Manager, Flashify.

ROM Manager

ROM Manager is the easiest way to update your tablet operating system at home with minimal experience.

Instruction:

Get root rights.
Install ROM Manager.
Create a backup.
Download firmware for tablet.
Select the "Install ROM from SD card" item in the ROM Manager menu and select the file with the firmware.
Wait for the end of the procedure.

The method works on Prestigio Multipad and other common tablet models.

Tablet firmware via SD card

For reinstalling windows or Android on a tablet, you can use an SD card. Sometimes the system asks for root rights.

This can be done using programs:

root checker. A simple software for checking the availability and correct installation of superuser rights.
FramaRoot. Download and install the apk file in the device memory. The utility contains a bypass of Android protection, so the built-in antivirus can block the software.
kingroot. Suitable for most Android versions and mobile device models. To manage the acquired rights, you additionally need to install KingUser.

You will need Bootloader Unlock (there are program options for different smartphones and tablets: Asus, HTC, Samsung).

You can unlock the bootloader in another way, for example via a PC:

Get the unlock code on the manufacturer's official page. The code is available by IMEI or Product ID.
Connect your smartphone or tablet to your PC via USB and enable debug mode.
Go to the Android SDK - Platform Tools folder. Hold Shift, right-click and select "Open Command Window".
Enter the desired command: fastboot flashing unlock for Acer, fastboot flash unlock unlock.bin for LG, etc.

Go to the "For Developers" menu. Enable OS installation mode.
Reboot device in install mode operating system(press the volume and lock keys).
After the installation of the system is completed, you need to restart the tablet. The first activation can take a long time - up to 10 minutes.

Reinstallation via a USB flash drive is more complicated than the procedure via a PC, due to the need to install additional software. But if the tablet or smartphone supports the built-in ability to reinstall the system, then dancing with a tambourine is not required. For example, everything is much easier on tablet computers running Windows.

Tablet computers on the Android platform are very popular today and are used by millions of people around the world. Including due to the convenience and versatility of this operating system, which makes it almost indispensable and has no worthy analogues yet. The advantages of Android are very significant: firstly, it is free, and secondly, a huge number of various programs for it, as well as high fault tolerance, reliability and speed. But despite a lot of advantages, many users sooner or later begin to think about how to flash an Android tablet, and there are reasons for this.

tablet on Android system, update the firmware to get new features.

Tablet firmware. What it is?

So what is firmware? This concept refers to the main control program mobile device, and any - tablet, smartphone, electronic player and conventional cell phone. home control program or firmware is nothing more than an analogue of the computer operating system. That is, all other software installed on the device works on the basis of the firmware.

Firmware can be different - both very simple, performing only a few functions, and quite complex, representing full-fledged operating systems. Just Android is one of such complex firmware.

The first installation of the Android OS on the tablet is carried out at the factory, after which the device goes on sale and after some time gets to its owner. It happens that at the time of purchase the version of the operating system has time to become outdated. Therefore, the owner has to puzzle over how to update Android on a tablet.

Why change the firmware?

The need to change the firmware may arise not only in order to install a new version, but also for a number of other reasons, for example:

To expand the functionality of the system - to achieve the ability to install the desired applications, remove some restrictions, for example, to run the required number of programs at the same time, increase user privileges, etc.
Reinstalling Android on a tablet is also necessary when the system starts to fail, “fail” - in a word, it doesn’t work the way it should.
To increase the level of privacy and security by getting rid of some features. Since it is known that Google system does not disdain elements of spying on its users - it is capable of sending the device's GPS coordinates, phone number, IMEI and other user data directly to its servers without the knowledge of the owner.
Changing the firmware also makes it possible to remove the previous installed applications that the user does not need.
If the tablet was purchased from a foreign online store or abroad, the Russian locale may not be available in the system. In this case, you just need to think about how to reinstall Android on the tablet. Because there is no other solution to this problem.
Some unofficial firmware can "squeeze more resource" out of the device's hardware, because they contain modified drivers.
And finally, a number of unofficial firmware opens up the possibility to modify the design of the system in a wide range, for example, add fonts, visual effects and other embellishments. Fans of design delights, of course, appreciate such opportunities very much.

Pros and cons of changing the firmware

Based on the goals described above, the following advantages of updating the firmware can be distinguished: this is, first of all, getting rid of restrictions, new functionality, solving problems with failures, or simply installing a more recent version of the system. However, reinstalling Android on a tablet can end badly if you choose the wrong firmware version or install it incorrectly. In this case, you can completely kill the tablet, that is, make it unbootable (although not completely - it is treated, but in the service and for money).

Another danger of installing unofficial firmware lies in modified drivers that will make the equipment work in abnormal mode. Yes, for a while you will enjoy the increased speed of the tablet or the cool sound of music, but this often causes premature wear and tear of the hardware, which means that you will have to spend money on repairs or buying a new device.

In addition, by installing a firmware modified by someone unknown, you can install integrated malware along with it. For example, various Trojans that spy on the user and steal personal data. In a word, thinking about how to reflash Android on a tablet, think about what it can turn out for you.

How to reflash an Android tablet yourself

And yet, if you decide, you should first study the instructions on how to put Android on a tablet, and also stock up on the firmware version suitable for your device model. In addition, you will need a microSD card, formatted in FAT32 just in case, and one or two programs that you will need to download from Google Play. So let's get started.

Step-by-step instruction:

First of all, you need to get root (superuser) privileges. This is done in order to install the ROM Manager application, with which we will flash the tablet. Getting root privileges can be done by various programs, such as GingerBreak, Z4Root, Universal Androot and others, most often in one click by selecting the "Root device" option.
After rooting, you will need to immediately download and install ROM Manager - this is a firmware program android tablet, which we will use. There are paid and free versions of ROM Manager. The paid (Premium) version allows you to download and install new firmware versions directly from the program itself without unnecessary actions. Therefore, you don’t have to think for a long time about how to update Android on a tablet, in which case you don’t have to. If you have installed free version- you will need to search for the firmware yourself.
After ROM installation Manager, go to its main menu and install ClockworkMod - it contains a new system loader. Also, just in case, save a backup copy of the system - the "Save current ROM" option.
Before you reinstall Android on your tablet, transfer the new firmware to microSD card and install it on your tablet. Next, fully charge the tablet, turn off all connected devices, except charger, launch ROM Manager and select "Install ROM from SD Card" from the main menu. This will start the firmware update process. On average, it takes 15 - 30 minutes. The first boot of a device with an updated system may take the same time, but you should not try to speed it up.
If you see an Android icon with an exclamation mark on the screen immediately after booting, you will need to perform a system restore. Clicking on the exclamation mark will take you to the recovery environment. From the menu that you will see, you will need to select the "Install ZIP from SD Card" command. Next, disable the verification of the crypto-signature of the firmware with the "Toggle signature verification" command. After that, select the "Choose ZIP from SD Card" option and specify the path to the firmware file on the SD card. The problem will be fixed and the tablet will be able to boot successfully with the new system.
If a new firmware something did not work, you can always return the old one back. How to restore Android on a tablet from a saved copy? Very simple! To do this, install ROM Manager again and select the "Backups" option from its main menu. The list of backups contains the one you saved previous version firmware, it remains only to select it and restore it in one click. Everything!

And a little caveat. When collecting information on how to flash n, do not forget to first inquire about possible failures and problems during the update process, since anything can happen. And remember that regardless of whether the process of changing the firmware was successfully completed or not, you lose the warranty on the tablet. Therefore, everything that you do is done entirely at your own peril and risk.

Android is an operating system. This program is used for tablets and phones. Android firmware makes it possible to install the system on the device so that the gadget functions normally. However, like any other program, it can fail or become outdated. To restore system functions or install a new version, flashing is performed. Even a beginner can carry out such manipulation. How to reflash android?

What is firmware?

Android firmware - installing the program on the microchip of the device. Such manipulation is carried out at the manufacturing plant. Based on this, it is easy to guess that flashing is a program update. Manipulation is performed in the following situations:

if the version of the operating system is outdated and you need to install a new version;
if there are any failures in the operation of the program;
if it is necessary to change the system language to Russian;
if you need to crack the protection of the program when the gadget is blocked.
