custom ROMs.[5]
ClockworkMod Recovery
ClockworkMod Recovery is an Android custom
recovery image. Once installed, this recovery image replaces the Android device's stock recovery image. Using this recovery image, various system-level operations can be performed. For example, one can create and restore partition backups,
root, install, and upgrade
custom ROMs.[6][7]
ClockworkMod Recovery is free and open-source software, released under the terms of the Apache License 2.0 software license.[3]CyanogenMod Recovery is a fork of ClockworkMod Recovery.[a]

Like the stock recovery, CWM can receive over-the-air updates for ROMs designed for their respective recoveries.
