Recovery inAndroid

How to manage menus in Android?

After the successful launch of the recovery window, the user should continue to work with it, choosing the necessary actions.

Please note that there are no auxiliary keys in the window and you cannot navigate between its tabs using normal touches.

The side buttons of the phone and the Home key are used to control the system menu. Move up and down or left and right using the volume keys.

Confirmation of the selection is by pressing the Home button.

To exit the recovery, click on "Power". Remember, never disable the system menu until the process has finished.

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

Start the phone after disconnecting, or use the keys to restart 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 manage system menu.

Explanation of the names of the modes

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

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

In order not to be mistaken with the choice of the desired item and to perform the correct setting of your phone, read the explanation of each option first:

Mounts with Storage Is a tab for memory management. With its help, you can format partitions of disk space or view the degree of use of internal and additional memory;

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

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

Wipe Cache Partition - clearing the device cache. Note that this function works much more efficiently than any third-party program for clearing the 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 files and user programs will be removed. 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 - start the device data backup mode or select a copy to restore user files and settings.

Stock and Custom Recovery. What is the difference?

Wait for your smartphone to be recognized in the installed program and click on the "Other download" tab.

In the field "SDK Tool" tick all the suggested options and save the changes. Wait until all packages are installed and close the program.

Now you can proceed to installing custom Recovery.

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

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

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

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

2 Install and Run Android SDK Utility on PC;

3 On your smartphone, enable Quick Install Mode. To do this, simultaneously press the Volume Down and Power On keys until the icon with the robot 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. The item will appear in the drop-down list. "Open in command window"... Click on it:

• In the command line window that appears, enter the command "FASTBOOT FLASH RECOVERY FIRMWARE_NAME.IMG" and press Enter. Note, FIRMWARE_NAME.IMG is a unique name for 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 running 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 theme you like... Flip to the right to unlock the screen to allow changes. Continue to use the updated with a convenient Russified menu for updating the OS, resetting to factory settings or managing memory.

If you have ever tried to flash either or an Android tablet on your own, then you probably came 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 do a full reset of the operating system, reflash the device, make a backup copy of the entire system or its individual partitions (just like restoring these partitions later) and some other things. At the same time, for this mode to work, the operability of the operating system itself is completely optional. That is why the recovery menu is often accessed when the device no longer works in normal mode. And that is why this mode is called “recovery”.

How to enter Recovery

To boot recovery, the hardware buttons of the device 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 special applications with which you can reboot your smartphone or tablet into recovery mode directly from the operating system itself (for example, the Reboot menu). However, keep in mind that these applications require a.

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 selection.

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 be quite different depending on the device. Particularly distinguished in this sense were the “noname” tablets from China and some B-brands, in the recovery of which there is no list of commands at all.

Every Android mobile device comes with an additional diagnostic software called recovery. The principle of operation and the concept of recovery on Android resembles BIOS in computers - this software is also installed separately from the operating system and performs diagnostic functions. What is recovery in Android - read our article on Treshbox.

Stock recovery Android

Recovery is software in Android devices used to diagnose hardware, restore the system, and create backups. Every smartphone from any manufacturer has such a mode of operation. The recovery pre-installed by the manufacturer is called stock. To enter the recovery mode, you must turn off the device and hold down a certain combination of hardware buttons. This combination is different for all manufacturers. You can also call the recovery using adb utility commands using a computer with an Android device connected to it.

Combinations for calling recovery on popular devices:

• How to enter recovery on Samsung Galaxy: with the gadget turned off, simultaneously hold down the Power, Home and volume up buttons. Clamp before entering the recovery.
• How to enter recovery on LG: with the smartphone turned off, simultaneously hold down the Power and Volume Down buttons. Press until the LG logo appears - then release, and then press these two buttons again at the same time. The menu for entering the recovery will appear.
• How to enter recovery on Google Nexus: with the device turned off, hold down the Volume Up and Volume Down buttons, and then hold down the Power button. “Start” appears and a selection menu appears. Press the volume down button to select recovery and press the power button to boot into this mode.
• How to enter recovery on most Android devices: on many devices of little-known or even large manufacturers, there is a single way to enter recovery - by holding down the Decrease buttons or increase the volume simultaneously with the Power button.

Stock recovery in Android

Even stock recovery allows you to install firmware, OTA updates, or restore the operating system to factory settings. However, in the stock recovery, you cannot install third-party firmware from the community - it is tailored only for updates and firmware from the official developer company.

Custom Android recovery

Custom recovery for Android has been created by the huge community of the operating system from Google. The custom recovery firmware depends on the device and the recovery itself, but after the firmware it will replace the stock analog. The recovery firmware is identical in meaning to installing a new firmware (from stock to CyanogenMod), but only here you switch from stock recovery mode to TWRP or Clockwork Mod.

TWRP recovery interface and functions

The possibilities of popular custom recovery are much wider than that of stock ones. For instance, TWRP (Team Win Recovery Project) allows you to create full backups of the operating system (NanDroid). Thus, it is possible to kill the system and return it to a working state, even if it does not boot. You can also install third-party firmware, reset the firmware to factory settings, mount partitions, use the terminal, and even change themes. The TWRP recovery has it. It provides access to all recovery functions (installation, backups, recovery) without having to reboot into the mode itself. The main feature of TWRP is a user-friendly touch interface with support for themes.

Clockwork Mod recovery interface

Another popular custom recovery for Android is Clockwork mod... It can be installed using the app, but only if you already have it on your device. CWM can create and restore backups, install firmware and hard reset the system. The main feature of Clockwork Mod recovery is additional functions for installing custom firmware. Unlike TWRP, the CWM interface is not so convenient and beautiful.

How to install custom Clockwork Mod recovery on Android - soon on Treshbox

The beauty of TWRP and CWM is also that they are open to the community. Anyone can take the code for these recoveries to port them to officially unsupported devices.

Installing custom recovery on Android

Soon there will be separate articles on Treshbox on how to install two popular custom recovery on Android - TWRP and CWM. However, it should be noted that such operations require an unlocked bootloader. Such instructions will also appear on our website - please wait.

Want to install custom firmware on Android or, in other words, a third-party OS version like CyanogenMod? You will most likely need to install custom recovery as well.

All Android devices have a recovery tool preinstalled. This recovery software can be used to restore the device to factory settings, update the operating system, or perform other tasks.

Stock recovery

Android devices come with Google's recovery tool, often referred to as "stock recovery". You can boot the recovery system by pressing certain keys on your smartphone or tablet, or using the adb command, which will boot your device into recovery mode.

The recovery menu provides functions to help you recover your device, for example, from here you can restore to factory settings. Recovery mode can also be used to update OTA files. If you want to install a new firmware on your device or restore the factory firmware, then you will first need to enter the recovery mode.

With stock recovery, the system is limited. It can be used, for example, only to update OTA files and firmware from the manufacturer.

Custom recovery. The basics

Custom Recovery is a third-party recovery environment. This is similar to installing custom firmware like CyanogenMod, but instead of replacing the operating system, it replaces the recovery environment.

The custom recovery environment will do the same as the stock one. However, it will also have additional functions. Custom recovery can often create and restore device backups. Custom recovery allows you to install custom firmware. ClockworkMod even provides a "ROM Manager" app that lets you access many features from a running Android system - this app requires custom recovery.

Popular custom recovery

ClockworkMod Recovery (CWM) can create and restore NANDroid backups - backups of the entire file system of an Android device. ClockworkMod provides a ROM manager with a file browser that allows you to view and install custom firmware via ClockworkMod Recovery and manage and restore backups. It also has other additional features that will be helpful when installing and working with custom ROMs.

Team Win Recovery Project (TWRP) is a click-through recovery environment. Unlike other recovery environments, including stock, where the volume keys are used for navigation, and the power key is used to select the power key, here an interface is used that can be used by pressing the screen. TWRP even supports themes. Just like CWM, TWRP provides the ability to install custom firmware and create and restore system backups, which is not in stock recovery.

CWM and TWRP are two of the most popular custom recovery tools, but other custom recovery tools may only be available for certain devices.

When and why to install Custom Recovery

Custom recovery environments come in handy if you will be installing custom firmware because they provide the ability to make a backup copy of data, as well as its restoration, which will undoubtedly come in handy. You will need to unlock the bootloader on your device in order to install custom recovery.

Although this feature is hidden and requires the use of adb commands. You don't have to unlock the bootloader, install custom firmware, or even root to create or restore a full backup.

Install custom recovery if you want to install custom firmware or get a powerful backup tool. This step is often seen as a preparatory step before installing custom firmware, but it is not always necessary. For example, the CyanogenMod installer will also install ClockworkMod Recovery (CWM).

In general, custom recovery is only needed if you plan on installing a custom ROM. Most Android users won't even notice the difference between custom and custom recovery.
