Recovery mode does not work. Recovery mode on Android

Like any operating system, Android has a special boot mode when the device turns on, but the system itself does not boot. This mode is called Recovery Mode, or recovery mode in Russian. This mode is present in any Android device and allows you to reset parameters, change firmware, restore firmware from a backup, or simply in case of a freeze. It is noteworthy that, unlike root rights, using Recovery Mode is not dangerous, and therefore is not blocked by the developer in any way. This function can be used by absolutely everyone and completely officially. Let's take a closer look at how to enter recovery on any device running Android, and what each menu item is responsible for.

Recovery Mode provides access to the system functions of the device

Ways to enter Recovery mode

On the device itself

Standard method. The principle of entering Recovery Mode is the same for all devices - when you turn it on, you need to hold down several buttons. Most often this is volume up, but the following options may also occur:

• Samsung - power on + volume up + Home.
• LG - power on + volume down.
• Google Nexus, HTC - power on + volume down, then tap Recovery.
• Certain Lenovo, Motorola models - power on + volume up + “Home”.
• Sony - power button, after double vibration, hold down the volume up.

If for some reason you cannot enter Recovery Mode using standard means, try checking the instructions. The listed combinations are valid in almost all cases and will work both to enter the standard recovery menu and the custom one. In addition, you can run it even when the tablet does not boot or the system freezes.

If you have root rights, you will need the Terminal Emulator application installed (https://play.google.com/store/apps/details?id=jackpal.androidterm). After installation, you will need to enable superuser rights and enter two commands: first su and then reboot recovery. The device will reboot.

Via computer

A prerequisite is that USB debugging mode is enabled (Settings - For developers - USB debugging, or select the appropriate item when connecting to a PC). Therefore, if this mode was previously disabled, the tablet will not start and you will not be able to use it.

You will need the ADB Run program (http://cloud-androidp1.in/Android/PC/Project_Site/AdbProgramm/), a cable and a working device.

1. Connect your device to your computer.
2. Launch the ADB Run program.
3. In the program menu, press 4 and then 3 in sequence.

The device will reboot into Recovery Mode. You can perform the procedures you need.

How to use Recovery Mode

As we have already said, there is both a standard recovery and a custom or custom one. Many experienced users claim that the capabilities of the first one are quite scarce, so it is better to install the unofficial one. We'll talk about them a little later, but now let's look at what Recovery Mode menu items you can find on your device.

Install zip from sdcard - installation of an archive with updates saved to a memory card. Through this menu, root rights are obtained and the firmware is installed.

Wipe data/factory reset - wipe data/reset settings to factory settings - completely clear the system partition, reset all settings to their original state. All apps and settings will be removed, but your media files will remain intact. Used for critical errors, system failures, or when new firmware is being updated. A particularly effective remedy in cases where the device does not turn on.

Wipe cache partition - clearing the system cache - the system partition in which temporary files and all program settings are stored. It is recommended to do this when the firmware is changed.

Backup and restore - system backup and restoration from previously created backups.

Mounts and storage - for correct operation, all sections of the system must be correctly mounted and connected. Often, this procedure is performed automatically, but sometimes something has to be corrected manually. You can also clear one of the partitions. We advise you to use this method only if there is a specific need, otherwise the file system will not load and the tablet will not work.

Advanced - additional settings, including rebooting Recovery Mode, clearing the dalvik cache, resetting system application permissions. Most often used by professional programmers.

Management, unless otherwise indicated, is carried out through (moving through the list) and power (selecting a menu item). In some cases, selecting is done with the volume up, and scrolling is done with the volume down. In any case, the system must indicate exactly how to manage menu sections. There are designs with touch control.

Unofficial Recovery

As mentioned above, the standard Recovery Mode very often has somewhat limited capabilities, so it is best to use third-party, unofficial developments. The most popular are two of them - ClockworkMod recovery (abbreviated CWM) and TeamWin Recovery Project (abbreviated TWRP). Both developments have excellent functionality and allow you to very quickly and conveniently modify or change the firmware, obtain root rights, reset settings to factory settings, or restore a backup copy.

CWM looks very similar to the standard one, only with a slightly different arrangement of menu items. Navigation through the menu is carried out using the volume buttons, and selection is made through the power button. There is a version with touch controls. Well, TWRP has an unusual tiled interface and is controlled via a touch screen. You can navigate through the menu by pressing the display, and you need to confirm the action by swiping. Some Android devices have one of these recovery installed either by default or with the standard one. Installing and downloading custom recovery may differ depending on the model, so look for information in the sections about your tablet model on specialized forums.

Conclusion

Once again, let's talk about the Recovery menu, since almost always instructions for flashing and upgrading Android involve performing certain actions specifically from the Recovery menu.

What is Recovery?

Recovery (recovery) or translated from English – Recovery Mode is a special boot mode for the device, with which you can restore the system or install updates. This is an emergency mode necessary to restore the working state of the mobile device in the event of program failures, which result in the device turning off and making it impossible to boot in normal mode.

Using Recovery mode you can:

1. Restart your tablet or smartphone.
2. Reset settings.
3. Install updates.
4. Configure and install firmware.
5. Get Root rights.
6. Delete your personal data located in the system.
7. Restore the operating system and much more.

Remember that incorrect actions can harm the system. If your tablet contains important information, it is better to save it on another device in advance.

Before using recovery mode, please read the instructions carefully. Each tablet has a service menu that is different from others, so the question of how to access the Recovery menu on a tablet requires an individual approach.

How to log into Recovery?

The Recovery mode in each mobile device is visually different, but the login process is almost always carried out according to the same principle. In order to enter the Recovery system, you need to do a number of actions:

1. Turn off the tablet. At the same time, make sure that the battery is fully charged or connect the tablet to the network.

2. Go to Recovery mode by pressing a combination of some buttons. Since different tablet manufacturers offer different hotkey combinations, we will provide several of the most common key combinations for entering the recovery menu.

Basic key combinations for entering Recovery:

• Simultaneously hold down both the “volume” keys and the “power” key;
• simultaneously pressing one of the “volume” keys and the “power” key;
• simultaneously hold down one of the volume buttons, the Home button and the device power button.

The buttons are held until the recovery mode appears on the display.

Some Chinese devices do not have a Recovery mode. In this case, you will have to reflash the tablet.

How to navigate through the Recovery menu?

Most devices allow you to navigate through menu items using the volume control buttons. The power button serves to select the desired menu item. Some devices may use other keys.

If the control is touch, then we move through the items and select the desired item by pressing with a finger.

How to enter Recovery if there are no volume keys on the tablet?

If your tablet doesn't have volume keys, try these tips:

1. You can try to enter the desired mode by holding down the Power and Home buttons at the same time. Another option is to hold down the Home key, press the Power button and release the Home key. After the splash screen appears, press the “Home” button again.

2. You can navigate through the menu by connecting a USB keyboard via an OTG cable or using the sensor.

If you have ever tried to flash an Android tablet yourself, you have probably come across the concept of “Recovery”. Today we will talk in detail about what this thing is, why it is needed at all, and of course, how to enter it.

What is Recovery

Recovery mode is a special boot mode for Android devices that allows you to completely reset the operating system settings, reflash the device, make a backup copy of the entire system or its individual partitions (as well as restore these partitions later) and some other things. At the same time, for this mode to work, the functionality of the operating system itself is completely optional. This is why the recovery menu is often accessed when the device no longer works in normal mode. And this is precisely why this mode is called “recovery” (from English “recovery”).

How to log into Recovery

To boot recovery, the device's hardware buttons are usually used. The most common combinations are:

However, some manufacturers may come up with “something like that,” so you have to search and experiment.

If everything is done correctly, a lying robot will appear on the device screen, on top of which there will be a menu with commands.

Another way to download recovery is through special applications that can be used to reboot your smartphone or tablet into recovery mode directly from the operating system itself (for example, Reboot menu). However, it is worth keeping in mind that these applications require .

Navigation in recovery mode is carried out mainly using the volume buttons, and selection using the power button. There are also devices in which only the volume down button is used for navigation, and the volume up button is used to confirm the choice.

To all of the above, it is necessary to add one important detail. The functionality of the recovery mode itself is by no means universal, and can differ quite significantly depending on the device. Particularly distinguished in this sense are “noname” tablets from China and some B-brands, whose recovery does not have any list of commands at all.

The Recovery menu is a special service mode of the Android mobile system. Available on all smartphones and tablets. Used to launch if the user wants to quickly clear all information on the device, restore factory settings, change the firmware, and also in some other situations.

If the Recovery on the device has never been changed, it is called STOCK. If this menu has been stitched, then it is already called CUSTOM.

Among custom recovery, CWM and TWRP are considered the most popular due to their functionality.

To enter the recovery menu on a switched off device, use a special combination of pressing HOME, POWER, VOLUME+ and VOLUME-. In this case, you need to use different of these buttons on different devices.

Below in the article you can find a method for your device. By the way, there are special programs for launching this menu. We will look at one of the most convenient ones called Quick Boot here.

A universal way to enter recovery on Android

Today, the same key combination is suitable for many models from different manufacturers. Therefore, it makes sense to consider this method first. Perhaps it can be called a universal method.

The procedure is as follows:

1. Turn off your Android smartphone or tablet.
2. Press the power button and then briefly press the volume up control.
3. The device will go into Recovery.

1. With the device turned on, press the on/off button for a few seconds.
2. A menu with some parameters will appear on the screen, where there may be a button “Go to recovery” or something like that.

If on your Android these key combinations do not lead to the desired result, then see below all the possible combinations specifically for each popular line of devices. For all other devices, one of the universal options described above is suitable.

Recovery on Samsung

If you have a device from the popular Galaxy line from Samsung Electronics, then one of the following methods will suit you. Keep in mind that all key combinations apply when the smartphone or tablet is turned off.

Methods:

Recovery on Sony Xperia

If you are the owner of a Sony Xperia line device, then turn off the device, and then turn it on and When the indicator lights up or the SONY logo appears on the screen, hold down the volume down or up key. On some models, clicking on the logo works.

This option is also possible: turn off the device, hold down the power button and wait for a few vibrations, then release the ON/OFF button and quickly press “Volume +”.

Recovery on HTC

First of all, the user needs to switch to Bootloader mode. In most cases, this requires removing and installing the battery again:

Recovery on Nexus

With the device turned off, hold down the following key combination: volume down and on/off (power).

Now find the Recovery option and go to it by pressing the Power button.

Enter recovery using the Quick Boot application

There are also special programs that help you switch to Recovery with one touch of your finger. The procedure in this case is not at all complicated. Just open the Play Store, search for the application and install it. I decided to introduce you to one of the most convenient ones called Quick Boot.

After installation and launch, select Recovery from the program menu.

The device will successfully reboot into Recovery mode, and you will be able to continue working with those partitions that you need, depending on the task at hand. For example, if you need to restore all factory settings on your device, you will work with the Wipe data (Factory reset) section, to update the firmware use the Apply update from section, etc.

How to work in the recovery menu

Navigation here is done by pressing the side volume up and down keys. To confirm the selected option, briefly press the on/off button.

Advice: if you are not sure of your actions, it is better not to experiment in this menu, as the consequences will be irreversible. Android mobile devices, unlike PCs, will not issue warnings about possible problems.

What's in the Recovery menu

This menu contains the following sections:

1. Reboot system. When you click on this item, Android will reboot in normal mode. In case you just went into Recovery out of curiosity, use this command to exit.
2. Apply update from . This section is used to update installed firmware from an existing distribution, install patches, etc. In this section, you can select the type of update from the following list:
   1) Internal storage - from an existing option, including from system memory, file storage, memory card;
   2) External storage - from some external device;
   3) Cache - from the internal system cache.
3. Backup/Restore. Each device stores a backup image of the system. When you click on this item, recovery from this image will be started. That is, the system will be completely updated to the state it was in after purchase.
4. Wipe cache partition. The contents of the system cache will be completely deleted.
5. Wipe data|Factory reset . Selecting this item will allow you to reset all settings made by the user over the entire period of operation. The device will completely return to its factory preset settings. Please note that during the reset process, all information entered and saved by the user will be lost. Including all files, folders, music, videos, etc. However, the performance of the tablet usually increases by an order of magnitude after resetting the settings.

Let's take another look at the tablet. We will need this menu whenever there is a need to reflash the device or upgrade Android, for example, to increase functionality.

What exactly is the Recovery menu of the tablet?

Main functionality of the Recovery menu:
- Restoring a previously saved state of the operating system;
- Deleting personal data stored in the system;
- ;
- ;
- Installing updates;

It must be borne in mind that incorrect actions in the Engineering menu can lead to disastrous consequences for the system. It is recommended that before any manipulations in Recover, you save the data from the device in a safe place.
The service menu of each tablet is individual, so before changing anything in it, we strongly recommend that you read the instructions carefully.
