If Android does not boot into Recovery mode. Recovery mode doesn't work

Every mobile device running on the Android operating system has a Recovery mode installed, which is a special system startup mode with a certain set of functionality. Today we will tell you about how to enter recovery on LG smartphones and why it is needed for a common user.

First of all, Recovery Mode is used to install official firmware, create and restore a complete copy of the operating system along with all information and settings of the smartphone, clear the cache, and sometimes to reset it to factory state. When you receive a firmware update over the air, it is installed from the recovery mode, without starting the OS itself.

In its stock (factory) state, Recovery mode has the following set of functions:

Apply update from ADB – installing the update via ADB commands

Apply update from external storage – installing an update from external storage

Wipe data/factory reset – deleting data and resetting to factory settings

Wipe cache partition - delete cache

Apply update from cache – apply update from cache

It is worth noting that using Recovery Mode does not void the warranty service, and the procedure itself does not foreshadow anything dangerous for the performance of the mobile device.

How to enter recovery on LG

Entering recovery mode is quite simple and does not require any special skills. First, turn off your smartphone. When turned off, press and hold the “Power” button and the “Volume Down” key until the “LG” logo appears, and then release them and press again. Ultimately, a menu should appear on the device screen on a black background, as in the main picture at the very top. That's actually the whole process of this operation. The desired action is selected using the volume rocker, and the “Power” button confirms the choice made. If you entered recovery mode for review and want to exit it, then simply select “reboot system now”.

For more advanced users, there are custom recoveries that offer more options, such as installing any firmware, including custom ROMs, as well as selectively clearing phone data and deleting unnecessary pre-installed applications. The most popular of them are called Team Win Recovery Project (TWRP), Philz Touch and ClockworldMod Recovery (CWM). The first two are controlled using a sensor, while the latter uses only physical buttons, as is the case with the factory Recovery Mode.

The device will go into Recovery.

With the device turned on, press the on/off button for a few seconds.

Step 2- Open the application, where you will see 4 possible actions: Recovery, Bootloader, Restart and Shutdown.

Step 3— Click on Recovery, after which the phone will reboot and automatically enter Recovery Mode.

It's simple, right? This is the easiest way, unless of course you know the correct combination of buttons to enter Recovery Mode specifically for your device.

Method 2: How to enter Recovery Mode using ADB

Another way to get into recovery mode. Use this method if you do not know the special key combination or you do not have Root access, which is required for the first method.

Step 1— Make sure that Fastboot is installed and correctly configured on your computer. (how to configure them is the topic of a separate article)

Step 2— Connect your Android device to your computer using a USB cable and install ADB drivers if necessary.

Step 3- Go to the folder android-sdk-windows\platform-tools and open Command Prompt (Shift + right click anywhere in the folder -> Open Command Prompt)

Step 4— Enter the command “adb reboot recovery” (without quotes) and press Enter.

Step 5— Your device will turn off and then boot into Recovery Mode. Moving up and down is done using the volume buttons.

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.
