Brief information and benefits of TWRP recovery

The TWRP (Team Win Recovery Project) is an open source community development project. With the flashing TWRP your device can install any firmware, start your smartphone, change zip files for settings, Xposed modules for settings, root and unroot processes in one click. You can also make a full backup of Nandroid and restore it later, flash the image file with a single click, remove bloatware, overclock and underclock. The TWRP allows you to easily erase, cache and delete data after flashing an image file to display changes and correct minor errors caused by caching.

To install TWRP, your Samsung Galaxy A21s SM-A217F/M/N phone must have an unlocked startup charger. This means that you first need to unlock the bootloader to install the root of the device, as well as to perform any configuration.
