Can't enter recovery mode. Recovery: what is it and how to use it? Simple explanation. Rare ways to log into Recovery

Second generation Samsung Galaxy J2 is officially released and available in various markets. So, if you have already bought this Marshmallow-powered smartphone, it's time to learn how to use it properly. But in order to become more experienced user android, you need to learn the basics first. In this regard, today we want to describe in detail the sequence of steps that must be performed in order to access the recovery environment (recovery mode) on new Samsung Galaxy J2 (2016).

In fact, we will describe in detail three various methods, with which you can enter recovery mode on the Galaxy J2. This is a basic operation in android that all users must know to properly manage the features and performance of their devices. Entering recovery mode is not difficult, it will help provide various benefits in terms of internal access to android.

Recovery mode is a specialized environment pre-installed on the Samsung Galaxy J2, just like on any other Android smartphone or tablet. This software can only be accessed when the reboot sequence is known - this is a precaution designed for an inexperienced user who, using the recovery system, can easily mess things up inside the Android M kernel. However, putting the Galaxy J2 (2016) into recovery mode is official a process that can be completed within a few seconds.

Since this is a supported/official operation, you will not have to use third party programs or complex and risky applications to perform the steps below. This way, you won't void your phone's warranty, and there's no risk of damaging the software while entering recovery mode.

But, what can you do using recovery mode? Using stock software (pre-installed on Galaxy J2), you can only perform supported operations, such as managing new updates, clearing app data cache, performing a hard reset, backup data and other similar procedures. On the other hand, if you choose to install a custom recovery image such as CWM or TWRP, you will be able to customize your phone by performing custom operations such as installing custom kernels, booting special programs from other sources, not only from Play Store, to increase the speed of your smartphone or increase battery life.

One final note: Installing a custom recovery image is an unofficial operation and will void your Galaxy J2 (2016) warranty. However, the steps in this guide can be successfully applied both when using stock recovery mode and when using custom Recovery mode, so you don't have to worry about it.

Thus, the recovery system is a software through which you can access and then modify the Android system running the Samsung Galaxy J2 (2016).

Be careful because if you are going to customize your Galaxy J2 with a custom recovery image, before you do anything, you should back up your data. Accounts and files - hard reset will be used for most of the user operations that will need to be performed. So, spend a few minutes of your time and save contacts, call logs, messages, internet settings, IMEI/NVRAM data, calendar, saved passwords, EFS folders, images, videos, audio files and anything else you may need later. Note: If you are using a custom recovery image, you may want to keep the current Android OS your Galaxy J2 is running on.

There is something else that must be taken into account: the battery charge must be above 40%, otherwise the battery must be charged. If you skip this step, the phone may turn off in the middle of the reboot process - as a result, or may appear.

How to enter recovery mode on Samsung Galaxy J2 (2016)

Use hardware buttons

This is the classic method; it will work if you turn off your Samsung phone first.
Wait for the shutdown process to complete.
Then press the Power button, Volume Up key and Home button at the same time and hold for a few seconds.
The recovery mode menu should automatically appear on your Galaxy J2.
In recovery mode, use the Volume up and down key to switch between options and the Power key to select the option you want.
At the end return to Android mode, selecting “reboot system now”.

Use the Android SDK toolkit

Another method involves initiating a special ADB command. But to be able to do this, first of all you must become a developer on your smartphone: go to the “Menu - Settings - About phone” section and click on the build number 7 times. Then in “Menu - Settings - Developer Options” select the USB Debugging tool. A computer will be required; install on it USB drivers for Galaxy J2 (2016) - you can do this using the toolkit Samsung Kies; In addition, install the Android SDK on your computer. And finally do:

Locate and open the Android SDK folder on your computer.
Turn on your phone.
Connect your smartphone to your computer - just plug in the USB cable.
From the Android SDK folder, open a command prompt window: press and hold the Shift key and at the same time right-click on an empty space.
In the command prompt window, type “adb reboot recovery”.
Wait until the Galaxy J2 (2016) enters recovery mode.

Using Third Party Applications

There are special applications in the Play Store that can help you complete the reboot sequence. An example of such an application is Quick Boot software. Thus, download and install this application on your smartphone. Then launch it and follow the on-screen prompts to complete the reboot process and enter recovery mode.

1. Use the keys

The simplest and most common way to enter Recovery Mode is to turn off the smartphone/tablet and press two or three buttons on the turned off (this is important) device.

Here are all the currently known combinations:

volume up + power button (Lenovo, HTC, Samsung, Meizu, Xiaomi, Sony, Huawei, Fly, Asus, Doogee, Bluboo, Blackview, Oukitel, Elephone, UMI and other Chinese devices);
both volume buttons + power key (Lenovo, Sony);
volume down + power on (Nexus, HTC, LG, Huawei, Motorola, Fly, Asus);
Home button + volume up + power (Samsung);
Home button + power (Samsung);
turning on + volume up until the logo appears and raising the sound again after it appears (relevant, for example, in Sony devices).

Depending on the manufacturer, the pressing method may vary. Sometimes you just need to press and hold until the Android recovery menu appears. In some cases, pressing all or one of the buttons once is sufficient.

On LG, you need to hold down the above keys exactly until the logo appears, and then release and press once again.

In Motorola, after using the combination, the so-called Fastboot Flash Mode will appear. Using the same volume keys you will need to go to Recovery Mode.

It's not that simple with Asus phones either. There you need to hold down the buttons until vibration appears, and after that only hold down the volume. This should be done until the desired mode appears.

Happy Xiaomi owners, when using the appropriate combination, will see a set of tiles with Chinese characters. There is no need to be afraid. Click on the button shown below (left) with the arrow, which will give you the option to change the language to English. Next, click “recovery” to enter TWRP.

Rice. No. 1. Go to recovery on Xiaomi

On Chinese devices, you also often have to additionally select “Recovery Mode” using the volume keys.

Advice: It is best to find the relevant information in the instructions or on the manufacturer's website.

If none of the combinations above worked for you, try others. At least one should work. And if not, you can always complete the task using a computer.

2. We use the capabilities of the computer

The process looks like this step by step:

To work you will need the Android SDK. You can download this program (the download files are located below, you need to select the file that corresponds to your operating system). Launch it.
After downloading, run the file with android.exe. Check the box next to “Android SDK Platform-tools”. Click the "Install 1 packages" button. If a window with a license appears, agree to it by clicking the “Install” button.

Rice. No. 2. Window Android installations SDK

Install the Java Development Kit from this page. There you also need to select the file corresponding to the operating system.

For reference: On the disk where you installed the Android SDK, a folder “tools_[Your version operating system]". And there is another folder in it - “platform-tools”. This is where ADB is located. This is just so you know.

Now download from the official website of your gadget manufacturer latest version drivers and install it.
On your smartphone/tablet, open Settings. Go to the “About phone” or, respectively, “About tablet” item. Find the “Build number” line there and tap on it 7 times.
A new item will appear in the settings - “For Developers”. Enter it. There, click on “USB Debugging” to enable this feature.

Rice. No. 3. "USB Debugging" in the "Developer Options" menu

Connect your device to your computer using a USB cable.
Run command line Windows. It is usually located in the Start menu. As a last resort, you can always enter “cmd” into the search and run the found program.
There, run a command like “cd \tools_[Windows version]\platform-tools”. Press "Enter" on your keyboard.
Next, run the command “adb reboot recovery”.

Rice. No. 4. Executing the reboot command

After this, the device will reboot and start in recovery mode.

Now you know how to log into TWRP using a computer.

3. Use the terminal

Android also has a terminal, like Linux. But you need to download and install it - here is the link. In that first enter the command “su”, and then “reboot recovery”. Between this, the program may request root access. Agree.

Rice. No. 5. Entering the command to launch recovery in the terminal

All this will help complete the task.

After purchasing a tablet or smartphone, many begin to study its functionality along with the instructions, in which the term Recovery Mode is often found. Let's try to figure out what kind of mode this is and why Recovery Mode is needed in your Android device.

Typically, developers or engineers use recovery mode. Its main purpose: installing and configuring custom (factory) firmware, creating or using a complete copy of the operating system (including all information and settings of the smartphone). Also sometimes Recovery is used for full reset settings to factory values.

Remember, using Recovey Mode on an Android system does not void the warranty on your smartphone. Entering Android recovery mode does not dangerous procedure, and even very “green” users can do this.

How to enter recovery mode?

Visually entering this mode may differ, but the principle is the same on all smartphones. And so for this you need:

1. Turn off your smartphone;

2. Hold down the volume control key (increase);
3. Do not release the volume while holding down the Home key;
4. Without releasing the previous two keys, press power on;
5. Wait for the android to load in recovery mode.

How to Use Recovery Mode in Android

In Recovery Mode, navigation (moving) through the menu occurs using the volume control buttons (up/down) and confirmation (Home) or the power key.

As a rule, this mode is different for many manufacturers, but the main content is always present:

apply sdcard:file.zip - the file file.zip is installed, which must first be uploaded to /mnt/sdcard/file.zip;
wipe data/factory reset - the data and cache partitions are cleared internal memory device, and also cleans system folder android_secure. Cleaning means removing all installed applications and system settings are reset;
wipe cache partition - the cache partition is cleaned (the section in which applications store their information).

Today we propose to talk about such an interesting and at the same time complex thing as (recovery for Android). The majority of users who have just switched to smartphones running operating Android systems, and has no idea how multifunctional it is. An indispensable part of this OS is the recovery.

Surely you started looking for what it is after something bad happened to your smartphone (does not respond to button presses, a black screen hangs, etc.). I'm right? Then you have come to the right place! In this material we will try to explain in as much detail as possible what it is and why it is needed.

Recovery for Android (Stock) - what is it?

This, so to speak, thing is present in almost everyone Android smartphone called Mode. Translated as “Recovery Mode”, presented as a separate menu, including a set software. In this mode the user can:

restore your device after any failure or virus infection;
update (flashing) the system;
install new patches;
reset the device settings to factory settings;
do backup copy;
create and mount partitions;
get ROOT rights (superuser rights).

As you can see, there are many possibilities. Manufacturers are trying to fit as many functions as possible into this mode so that the user can independently perform various actions with his smartphone without special skills.

You won’t find the Recovery menu on regular desktops or in your smartphone settings. The recovery is “hidden” deeper in the system, and can be accessed by holding down a certain combination of buttons when turning on the device (it may differ for each smartphone).

The stock menu can be difficult for the user to master due to what is presented on English language. In addition, control in recovery mode is carried out using physical buttons - touch controls do not work.

Stock recovery – what is it?

Typically, users who decide to figure out what it is will immediately find out that there are two types of recovery modes:

Stock (stock, native recovery) – provided by default by manufacturers;
Custom (custom, custom recovery) - a version modified by users, including more functions and capabilities (OCustom a little lower).

So, stock recovery is a recovery mode that is installed by the manufacturer of the smartphone or tablet. It is quite functional, it allows you to do everything that we listed just above, but with some reservations.

Stock does not provide for the installation of third-party firmware on the device - only official ones from the manufacturer.

For some, official firmware is enough (as a rule, owners popular smartphones, which do not remain without a fresh update for many years), for others (owners of models from little-known Chinese companies who forget about their brainchild after one update) - it’s really not enough.

For custom recovery, there are thousands of firmware developed by users themselves. So, on a smartphone long forgotten by manufacturers, using Custom you can install relatively recent, albeit not official, firmware. But we’ll talk about customs a little lower.

For clarity, watch the video, which describes in detail the recovery mode on Android:

How to access the menu on Android?

Understanding what it is and what it is for is much easier than getting into it. The fact is that many manufacturers have a different set of physical buttons: one smartphone has three, another has four. As a result, the combinations are also different.

As a rule, the power button and volume rocker are used. They must be held until the menu appears.

Below we will tell you how to enter recovery mode for the most popular Android smartphones.

How to get to Recovery Mode on Samsung

connect the smartphone via USB to the PC;
run the program (we recommend using “Run with administrator rights”);
wait for it to load;

we will see a list of possible actions presented in English;

we need the item “Reboot Devices”, which is presented under the number “4”;

Enter “4” from the keyboard and press “Enter”;

the following window appears;

Now select “Reboot” (reboot into recovery mode), the item is located under the number “5”, so we type it on the keyboard, press “Enter”;

your smartphone will reboot in Recovery Mode.

Way 2 – “adb reboot recovery” command

If for some reason the first method did not work (although this is unlikely), there is another one. Let's launch again adb program Run, where:

enter the number “7” (go to the “Manual Command and Unlock Bootloader” window) and confirm with “Enter”;
in the next window, enter the number “1” to access the Adb command line;

here we enter the command “adb reboot" and confirm by pressing "Enter";

wait a few seconds until the smartphone reboots into .

Method 3 - commands for specific models

It’s rare, but it happens that the two above methods do not help (most often happens with LG smartphones). In this case, it is recommended to use other commands. What we do:

also go to the Adb Run command line (read above);
enter one of the commands: adb shell, reboot recovery or adb reboot –bnr_recovery;
After a few seconds, the smartphone will reboot.

Custom recovery – what is it and what are the differences?

Custom, as already noted, is a third-party recovery mode. Its main advantage over Stock is the ability to install a wide variety of firmware, and not just official ones.

Modified recovery (Custom) - the simplest and convenient way installation of third-party firmware.

The most common are two types of custom recovery:

TeamWin R ecovery (TWRP);
ClockworkMod Recovery (CWM) .

TWRP

TeamWin R ecovery is an unofficial modified recovery; there are versions for almost all devices running the Android operating system. It boasts significantly greater capabilities than native Recovery. TWRP is often installed on smartphones by default, and can also be installed in parallel.

TWRP differs from the native recovery menu not only in its expanded functionality with the ability to install any firmware, but also in the presence touch control. We can also reset settings, create backups and mount partitions. You can download TeamWin R ecovery for free, about installing custom recovery below.

CWM

ClockworkMod is a popular analogue of TeamWin, which also offers an expanded set of functions and capabilities. You can find a version for almost every smartphone, with the exception of the most ancient models.

Many modern devices receive CWM by default.

Like its analogue, the main task is to help the user install third-party firmware on the device. In addition, CWM is ready to help you obtain ROOT rights, which will be useful to many. Controls in this recovery can be done in different ways, but in most cases the volume up/down buttons and the power key are used. Also, on the Internet, it will not be difficult to find a version of CWM touch, which allows you to select the necessary functions by touching the screen.

Installing custom recovery TWRP and CWM

You can install Custom in several ways, which differ significantly from each other, in addition, they may be suitable for one device, but incompatible with another.

Installing recovery via fastboot

F astboot is a section in the recovery menu, so this method is often called native.

That is, to install Custom in this way, your device must have stock recovery, which you will have to enter using one of the methods we discussed above. In addition, files will be required for installation and operation.

Recovery files need to be downloaded for specific model! If you try to download and install a recovery that is not for your model of smartphone or TV set-top box, you are guaranteed to get a brick!

In addition, in order to install recovery via fastboot, you must first unlock the bootloader.

Unlocking is done so that the device does not “resist” when you start installing a custom recovery or getting ROOT rights. Ways unlock bootloader there are plenty, but for each device it is preferable to use a specific one. Read more about unlocking in the topics for a specific smartphone.

Instructions

So, the instructions for installing Custom via fastboot are as follows:

make sure that your smartphone has recovery;
unlock the bootloader (look for information on thematic forums of your device);
download the Android SDK package, which includes a set various programs and files;
look for and download a version of the Recovery.img file specifically for your device (again, go to thematic forums);
rename the downloaded file to “recovery.img”;
move the file to the “platform-tools” folder;
connect the device to the PC by setting the FastBoot mode in Android SDK Tools;
launch the command line on the PC (“Run” – cmd);
here we write: “cd (space)” full path to the platform-tools folder”;

now enter the command : "fastboot flash recovery recovery.img";

We wait while the installation is completed.

Installing recovery via RomManager

This method, although it is one of the simplest, is not recommended, as it carries a number of nuances.

firstly, you need ROOT rights;
secondly, you need to make sure that your device is compatible with the application (otherwise there is a high risk of getting a “brick” (an inoperative device, which (not always) can only be restored in a service center).

So, if you decide to install recovery this way, then:

we get ROOT rights;
download the RomManager application (from the Play Market or from other sources);
we launch it, granting superuser rights;
Click on the “Install” item;
wait for the end;
To get to the recovery menu, select “reboot to recovery”.

Other ways to install custom recoveries

We told you about two of the most popular ways, we recommend using them first. True, in some cases this is not enough, so users have come up with many more ways to install Custom. And smartphone manufacturers are not particularly hindering their distribution.

The current option, if the first two methods do not work, is to flash the device using special software. For example, Odin software is designed specifically for Samsung devices, and SP Flash Tool is a tool for smartphones on SoC MediaTek, in Motorola smartphones – RSD Lite.

We recommend that you choose the method directly for a specific device model so that there are no compatibility problems. Look for information on thematic resources in topics dedicated to your device. For greater reliability, do not hesitate to ask questions to other users on the forums.

How to flash an Android device through recovery?

As a rule, users look for information about when there is a need to flash the device, and through the recovery menu this process can be made as fast and simple as possible.

If you are going to install the official version of the firmware, then it is not necessary to install a custom recovery, otherwise you will have to.

You can try to find the official firmware for your smartphone on the manufacturer’s website, but not everyone makes them publicly available in order to protect them from interference with the code by hackers. Also, a copy of the official firmware is often shared by owners of similar devices on the relevant forums. Search.

So, the firmware process actually takes half an hour at most, if you understand all the features:

download the firmware file (we find it specifically for your smartphone model);
if the firmware is third-party, install custom recovery (instructions above);
move the downloaded file to an external memory card;
boot the smartphone into recovery mode (instructions above);
look for the item “Apply update from external storage” and indicate the path to the firmware file;
confirm actions;
wait for the device update to finish;
It wouldn’t hurt to clear traces of past software (look for the “Wipe data/factory reset” item);
To complete the firmware and boot the device, click “Reboot system now”.

Ready! Your smartphone should boot successfully, appearing in an updated form.

Naturally, updating Android firmware through recovery does not always end successfully. Often smartphones refuse to be flashed using stock recovery; flashing often requires additional steps, as well as a connection to a PC. However official firmware in most cases it gets up without problems.

Bottom line

Well, today we told you everything about Recovery in as much detail as possible. We tried to convey the material very clearly so that none of our readers leaves without an answer.

At one point, it can really save your device by resetting the settings or creating a backup copy, and custom recovery will help you install your favorite firmware with updates. We hope you can now figure out the recovery menu without the help of a specialist.

What is the recovery menu, how to enter it, what is it for? These are the questions that novice Android device users often ask, so let’s try to answer them.

Every Android device has a special boot mode - " recovery mode" (recovery mode). Stock recovery (stock recovery) is quite limited and is recommended to be flashed on custom (custom recovery) for greater opportunities.

If Recovery menu didn't change, then it is called " Stock recovery" (stock recovery).
If Recovery menu cheated, then it is called " Custom recovery" (custom recovery).

There are mainly two types of custom recovery CWM And TWRP.

What functions does it perform?:

Full reset android devices to factory settings ( Wipe).
Installation of various modifications for firmware.
Installation of the firmware itself.
Receipt.

How to log into Recovery on various devices:
