TeamWin Recovery Project (TWRP) is one among the most popular custom recoveries for Android devices. ClockworkMod (CWM) recovery and TeamWin Recovery Project (TWRP) recovery are so extensive that a regular Android user can’t deny the temptation to replace their boring stock recovery (the default recovery that comes with the device) with either CWM or TWRP. Though CWM is relatively a bit more popular, TWRP has over the time become quite a good contender to the latter.
