What is a recovery mod? Android stock recovery

Today we propose to talk about such an interesting and at the same time complex thing as (recovery for Android). Most users who have just switched to smartphones running the Android operating system have 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 every Android smartphone called Mode. Translated as “Recovery Mode”, presented as a separate menu that includes a set of 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;
• make a backup;
• 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 the fact that it is presented in English. 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 of popular smartphones, which do not go 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 not even 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. Run the Adb Run program again, 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) is the easiest and most convenient way to install 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 of touch controls. 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 a 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. There are plenty of ways to unlock Bootloader, but it is preferable to use a specific one for each device. Read more about unlocking in the topics for a specific smartphone.

Instructions

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

1. make sure that your smartphone has recovery;
2. unlock the bootloader (look for information on thematic forums of your device);
3. download the Android SDK package, which includes a set of various programs and files;
4. look for and download a version of the Recovery.img file specifically for your device (again, go to thematic forums);
5. rename the downloaded file to “recovery.img”;
6. move the file to the “platform-tools” folder;
7. connect the device to the PC by setting the FastBoot mode in Android SDK Tools;
8. launch the command line on the PC (“Run” – cmd);
9. 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:

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

Other ways to install custom recoveries

We told you about the two most popular methods, and 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, the official firmware installs without problems in most cases.

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.

Recovery mode (aka recovery) on Android is a special hidden menu and is available on any Samsung Galaxy smartphone. This is a great tool that can be used to wipe data, reset settings, format the system partition, install a custom kernel, new firmware and many other things that should allow you to improve your smartphone and its system.

Recovery mode can be stock or custom. Stock Recovery Mode is the first and original option that is installed initially on a smartphone and you can work with it immediately after purchase. This mode works on a stock smartphone or one already rooted, but not on a Galaxy smartphone that is flashed with custom firmware.

Custom Recovery Mode can be installed only after obtaining root rights on the smartphone. There are two most popular custom recoveries for Galaxy smartphones ClockworkMod - CWM and TWRP - Team Win Recovery Project. Both of them are very similar in their features and you can get the same features in either of them. Below you will learn how to boot a Samsung Galaxy smartphone into recovery mode.

How to boot a Samsung Galaxy smartphone into stock/CWM/TWRP recovery mode:

• Turn off the device completely.
• Press and hold the Volume Up button, Home button and Power button at the same time.
• Release the buttons when the smartphone screen turns on and you will see the stock/CWM/TWRP recovery logo.

After you release the buttons, you will already see the main menu of the recovery mode. Here you can set the necessary settings or perform important actions on the system, including installing custom or other stock firmware.

To boot in normal mode, you need to return to the main screen of recovery mode and select “Reboot system”.

Every smartphone user has heard at least once the concept of recovery , let's figure it out What is this , in what cases you should use the mode and how to launch it on your device.

Definition

Recovery (recovery mode)- This is factory software that is included in mobile and desktop operating systems. The purpose of the work is to back up data, configure system parameters of the phone/computer.

By logging into Recovery you can:

• Recover device errors;
• Flash your smartphone or reinstall the OS on your computer;
• Get superuser rights.

Let's take a closer look at how it works in all popular operating systems for smartphones and computers.

Recovery inAndroid

How to manage menus in Android?

After the recovery window has been successfully launched, the user must continue working with it, selecting the necessary actions.

Please note that the window does not have any auxiliary keys and you will not be able to move between its tabs using regular touches.

To control the system menu, use the side buttons of the phone and the Home key. Move up and down or left and right using the volume keys.

Confirming your selection is by pressing the Home button.

To exit recovery, click on “Power”. Remember, never disable the system menu until the process is completed.

This can seriously damage your device (cancel firmware update and data recovery).

Start the phone after disconnecting or use the reboot keys in the system menu itself.

If the volume keys do not work on your gadget, you can connect a regular mouse to the device using a cableOTG and easy to operate system menu.

Explanation of mode names

Depending on the device manufacturer, the design and placement of tabs may differ, but the set of functions and control principles remain the same.

In 99% of cases, the recovery menu is displayed in English.

In order not to be mistaken in choosing the right item and to configure your phone correctly, First read the explanation of each option:

Mounts with Storage – This is a tab for memory management. With its help, you can format disk space partitions or view the usage of internal and additional memory;

Reboot system – forced reboot of the device at the moment. In practice, this function allows you to quickly rid your smartphone of most software problems without the need to reset to system settings. After a reboot, all user files and applications are saved;

Install from SD – launching the installation mode of the archive with firmware, which is stored on the memory card. If you want to flash your smartphone manually, you should first download the ZIP archive from Android for your device onto the card and then use Recovery to start the OS reinstallation process;

Wipe Cache Partition – clearing the device cache memory. Please note that this function works much more efficiently than any third-party program for clearing cache and temporary files;

Factory Reset (or Wipe Data ) – return the gadget to factory settings. As a result, you will receive a smartphone with the firmware version that was installed by the manufacturer. All user files and programs will be deleted. The settings are also not saved. Before performing this process, we recommend that you create a backup copy of your data and upload it to the cloud;

Backup or Restore – launch a device data backup mode or select a copy to restore user files and settings.

Stock and Custom Recovery. What is the difference?

Wait until your smartphone is recognized in the installed program and click on the “Other download” tab.

In the “SDK Tool” field, check all the proposed options and save the changes. Wait for all packages to be installed and close the program.

Now you can proceed to installing custom Recovery.

To install a third-party TWRP recovery menu, you will need a downloaded archive with a custom version.

Don't forget to select your device model and manufacturer.

Save the resulting archive in the memory of your PC - any directory and system drive. Follow instructions:

1 Make sure that your smartphone included and the BOOTLOADER bootloader is unlocked;

2 Install and run the Android SDK utility on your PC;

3 On your smartphone, enable quick component installation mode. To do this, press the Volume Down and Power buttons simultaneously until the robot icon appears;

Phone to computer connection field follow these steps:

• Open the folder with the downloaded custom Recovery firmware. It must be in IMG format. Click on an empty space inside the firmware folder while holding down the Shift key. An item will appear in the drop-down list "Open in command window". Click on it:

• In the command prompt window that appears, enter the command "FASTBOOT FLASH RECOVERY FIRMWARE_NAME.IMG" and press Enter. Please note that FIRMWARE_NAME.IMG is the unique name of the file with the custom Recovery image, which is located in an open folder on the computer.

The installation result will be displayed.

After installation, try launching a new Recovery. To do this, use a unique keyboard shortcut for your smartphone or tablet.

Detailed instructions for launching the recovery menu are described at the beginning of the article.

After the first launch, you need to select the interface language and the design theme you like. Unlock the screen by flicking to the right to allow changes. Continue to use the updated version with a convenient Russified menu for updating the OS, resetting to factory settings or managing memory.

Fig. 13 - first setup of the TWRP custom menu

Any device with Android OS starts in Recovery mode. This is a standard feature. However, with the factory version you can perform too narrow a range of tasks. So, this is resetting the phone to its initial settings, clearing the cache, and also updating the system from the update.zip file. Obviously, users who are expanding their knowledge in the IT field are very dissatisfied 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 replacement for the factory one.

Why do you need CWM Recovery mode?

Clockworkmod Recovery (CWM) is a famous alternative to factory recovery mode developed by Koushik Dutta. You can install it on most Android devices. CWM Recovery helps even in situations that sometimes seem hopeless to the average owner. That is why it is necessary to know about its existence, and also 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, add-ons and OS 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 the device from a previously created backup.

Resets to factory settings (Wipe - data/factory reset), clears cache (wipe cache), clears 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, companies themselves produce separate utilities, for example, Acer Recovery Installer for Acer devices. CWM is implemented into the device memory on these devices also through ADB software, which is suitable for devices manufactured by HTC.

Rom Manager: Rooting and embedding

Rom Manager is a utility created by CWM developers. It is available for download on 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 must root the device, that is, obtain administrator rights.

Obtaining 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.

Download the app from the store and open it. In the drop-down line, give preference to the “Install SuperSU” or “Install SuperUser” item. Click on the drop-down window

Select a method for obtaining Root rights. Follow the advice - restart the device for the changes to take effect.

For the changes to take effect, restart the device

Launch Rom Manager

Now is the time to use the program:

Launch the software and click on the first section of Recovery Setup, and then click on ClockworkMod Recovery. Select Recovery Setup

Find and select the device model from the list of available ones. If the model is not in the list, then this method of flashing Recovery is not suitable and you need to use another one. After confirming the action, the files will begin to download, as indicated by the progress bar. Next, a notification will pop up stating that you need to grant Root rights to the program. Then the CWM installation itself will be carried out. Click on ClockworkMod Recovery to install

Video: how to flash Recovery with Rom Manager

Although the method is easy, it has a drawback: it is not suitable for all devices, as mentioned 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: Complex Method

The CWM installation method 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 installation, 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 you need to have before installing CWM using FastBoot mode:

A computer with Windows OS and a 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 necessary Android SDK Tools and Android SDK Platform tools packages:

Go to the bottom of the official page. There will be three options. In this case, it is the Windows version. Click on tools_version-windows.zip.
Download the Anroid SDK zip archive for Windows from the official website

Extract all contents from the archive to drive C. Open and click on tools. The android file needed to download the packages directly is there. Double click on the file and the manager is open.
Find the android file in the unzipped folder and open

Check the box to the left of Android SDK Platform-tools and click Install 1 package.

Select Android SDK Platform-tools and click Install package

Standard request to accept the license agreement. Check the Accept License box and then click Install. The direct installation of the packages necessary for the firmware, which were mentioned earlier, will begin.
Accept the license agreement

After the installation process is complete, find platform-tools in tools_version-windows. It will contain important fastboot and adb files.
The fastboot and adb files are located in the tools_version-windows folder after installing the Android SDK Platform-tools package

What else needs to be done before starting the firmware itself? Judging by the list above, you need the recovery-clockwork.img file. This is one of the key tools for further work. Downloading it won't be difficult, but it doesn't end there. 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

Get 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.

First, connect the device to be flashed to your computer via USB. At the same time, FastBoot mode is launched (a combination of the power and volume down keys). Although this combination works most often, it is not suitable for everyone. In some cases, this is the Home key and the same volume reduction. When the first option doesn't work out, nothing will happen if you use the second.
Start your device in FastBoot mode

The main procedure is performed on the command line. First you need to open it. In a Windows terminal window (press Win + R keys) write the cmd command.
To open the command prompt, go to Start and type cmd

The command line is immediately ready to use. Type cd / immediately after the last entry and press Enter.
Type cd / and press Enter

Next, you need to go to the platform-tools folder in the terminal itself. The path to the folder may differ among users, so it is extremely important to use your own option so that the operation ends with a certain success. Copying the path from the window line would be the correct solution.

The next line in the black window should look like cd path_to_folder_platform-tools. Press Enter again.
Enter the command with the path to the folder

The next step is the adb devices command. It will help determine whether the PC sees the device. Next type adb reboot bootloader. Wait until the device turns on as a bootloader. Finally, go to the final part of the firmware: enter fastboot flash recovery recovery.img. and press Enter.
The adb devices command will help determine whether the PC sees the device

If successful, a message will appear. The next time you restart the phone in recovery mode, check that the new firmware is installed. If all is well, the device will enter ClockworkMod Recovery mode.

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. Detailed instructions were given earlier in the section on Rom Manager.

How to work with Rashr

First you need to download the application itself. It is available for free in the Play Market (Rashr - Flash Tool). You can also watch the program on a third-party site, but you need to 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. Then everything is simple:

Select CWM Recovery. Click CWM Recovery

The software will provide available versions of Recovery for the given device being flashed, such as the touch ClockworkMod and the option with key control.
Select Recovery from the list of options available for your device

Select the most suitable version and click Yes to confirm the download.
Click Yes to confirm download

After downloading, a notification will pop up that the new recovery has been successfully downloaded and installed. To go there, click Yes.
To go to Recovery, click Yes

Video: CWM and Rashr

Odin: solution for Samsung

The previous three methods are suitable for different device models. 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:

Download Samsung Odin from the official website.
Download the Odin program on PC

Establish a connection between the PC and the gadget via a USB cable and switch the device to Download Mode. There are two options depending on the device model. If one doesn't work, another will definitely work:

• power/lock button and volume down (on older devices released before mid-2011);
• power/lock button, Home and volume down (all other devices).

Pressing the volume up button confirms entering recovery mode. Next, launch the already downloaded Odin program. A program window will open, where available files for download will be listed. In the case of Recovery firmware, you need to check the box to the left of AP. In other versions of the software, the field may be called PDA.

Click the Start button and wait until the firmware is completed successfully.
Click the Start button and wait for the firmware to finish

How to enable CWM Recovery mode after flashing

Once CWM mode has been installed 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 “Load Recovery mode” section on its initial page;

by pressing the keys simultaneously after turning off the device. Combinations may vary 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 arise. 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 your phone using an 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 card formatting standards. To ensure formatting is performed in accordance with the specification of SD/SDHC/SDXC flash cards, and not just in standard form, it is recommended to use specialized software, for example, SD Formatter.

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

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

When the recovery files are located on the internal memory, and therefore can only be recovered from there, a problem may arise. When you connect the USB cable to the PC and enable USB Debugging, the program reports that the Android device is not detected and you need to enable USB Debugging.

To solve this problem:

Connect the device as a camera, not a storage device. If there are other options available, choose them.

Install universal drivers.

Find a more suitable Recovery program for your device.

Recovery menu doesn't work

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

The problem is solved as follows.

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 you should get into the custom recovery menu anyway.

In it, select Reboot system now and then check Yes. This action will overwrite the stock recovery with the custom one and the "No command" error will be fixed.

Flashing a new Recovery mode means acquiring new functionality. Firmware methods vary in complexity, but ironically, the simplest of them require access to Root, that is, device administrator rights. When choosing a firmware method, you need to be guided by the phone model first. Rom Manager is not suitable for all devices. For HTC, the FastBoot method is more suitable, while for Samsung it would be more correct to choose Odin.

Recovery is also called Recovery Mode for android. It is a special mode through which the Android simultaneously boots and restores the system or updates it.

Recovery starts when a certain key combination is pressed. It is different for every device. For example, for Samsung it is “Home” + “Power” + “Volume Up”, and for Nexus it is “Volume Down” + “Power”. You can find out the exact combination of your android via the Internet.

Types and features of Recovery

Since it is software, it is being written by someone. Depending on the creator, the recovery is divided into two types:

1. Stock Recovery - is created by the manufacturer "native" for the device.
2. – an alternative version that is created by individual programmers. Has more features than the official one.

The “basic” capabilities of this mode are as follows::

1) restart android;

2) install updates on Android;

3) flash the phone, that is, reset the data to factory settings;

4) copy and restore the system;

5) delete the cache from the device;

6) install the archive from the memory card;

7) enable USB-MS mode to transfer data to SD.

Custom Recovery, in addition to the above, has many more functions. For example, you can, but selectively, saving the necessary files.

There is also Photo Data Recovery - a program that we will talk about below.

Navigation and Custom Recovery menu

You can “move” around the Custom mode using the following keys:

“VolDOWN” – down, “VolUP” – up, “POWER” – back, “CAMERA” – select an item.

The main menu items are listed below to make it easier for you to understand the English language:

2) formatting the internal partition - wipe data/factory reset;

3) installing firmware from a memory card - install zip from sdcard;

4) backup and restore;

5) advanced recovery mode - Advanced Restore;

6) formatting the “download” section - format boot;

7) formatting the “systems” section - format system;

8) formatting the “date” section - format data;

9) formatting the “cache” section - format cache;

10) formatting the memory card - format sdcard;

11) formatting the Linux partition - format sd-ext;

12) connection to a computer in the form of a flash drive - mount USB storage;
