What is a Stock Recovery?

Each and every Android device model do come with its own stock recovery mode along with the stock firmware (preinstalled). Now, talking about the Android Stock Recovery, it’s a bootable partition of your Android device that is installed in the recovery mode which can be accessed by using a combination of power+volume buttons. The combination buttons can vary depending on the model or brand.

So, the stock recovery mode on your device offers a few useful features like factory reset, reboot to bootloader, software update, etc. To recall, the stock recovery also boots up every time whenever you power on or restart your device system. Now, you may ask why do I suppose to keep or use a stock recovery.

Importance of a Stock Recovery

As the name suggests, the stock recovery mode works to recover an operating system running device when it fails to boot into the system or stuck at bootloop issue or the phone freezes during boot logo, etc. Therefore, you basically need an official stock recovery partition of your device model in order to recover the phone back into the working status.

Though a stock recovery mode on an Android device comes with very few options to play with it like system reboot, apply update from external storage, factory reset, wipe cache partition to clear junk files, and more. You can also take backups on some devices using the stock recovery. Most importantly, plenty of Android users perform flashing a custom firmware or rooting and end up with a bricked device or bootloop issue. Therefore, flashing a stock firmware with stock recovery can do the fix quite easily.
