What is TWRP recovery?
Team Win Recovery Project (TWRP) is an open-source software custom recovery image for Android-based devices. It provides a touchscreen-enabled interface that allows users to install third-party firmware and back up the current system, functions often unsupported by stock recovery images. It is, therefore, often installed when rooting Android devices, although it isn’t dependent on a device being rooted to be installed.
