What does it for? In the past, a phone is more of a device used to make calls or text. However, it's much more than that.
Most Android devices are now defaulted with a fairly simple Recovery mode with features like Reboot System Now, Apply Update from ADB, Apply Update from External Storage, Wipe Data/Factory Reset, Wipe Cache Partition, Apply Update from Cache.
Just like a lot of other things with Android, even the Recovery Mode can be customized to do more things.
1. Lets get started, press and hold power button to turn off your device.
2. When your phone is turned off you have to press and hold both Volume down button and power button at the same time.
3. Wait for LG logo to appear and let go off the buttons.
4. Now there should be a recovery mode menu on your screen.
5. Now you know how to put your phone in Recovery mode, congratulations!
All Android phones come with built-in recovery mode that is separate from the original operating system.
The recovery mode is used to access different features of the phone without accessing the phone’s OS.
The main function of the recovery mode is to fix the phone while staying away from the faulty OS of the phone.
