Team Win Recovery Project (TWRP), pronounced "twerp",[3] is an open-so[4]urce software custom recovery image for Android-based devices.[5][6] It provides a touchscreen-enabled interface that allows users to install third-party firmware and back up the current system which are functions often unsupported by stock recovery images.[6][7][8][9] It is, therefore, often installed when flashing, installing, or [1] Android devices,[10] although it isn't dependent on a device being rooted prior to installation.
