TWRP for the HTC One for Verizon

by

End-of-Life, 21 Mar 2017: No further updates are planned for this device.

TeamWin Recovery Project (TWRP) is an open source recovery system for Android devices. Beyond basic features like backup, restore, and the ability to install a new or updated version of Android, TWRP includes numerous additional features:

  • The GUI is XML driven and themeable
  • Partitions can be formatted to a new filesystem type
  • The boot and recovery (yes) partitions can be flashed directly
  • Decryption of AOSP encrypted /data is supported
  • Backups can be encrypted
  • … and quite a bit more

Fork information

Beginning with version 3.0.M0-0, a forked TWRP repository is used to build releases. This has largely been done to remove the headache that is associated with keeping TWRP compatible with so many (old) Android build systems. For example, the cm-14.1 branch is only designed to be built with LineageOS 14.1. There are other minor changes that are described in the README, but it should be noted that the feature set is largely the same as in official TWRP releases.

Guides

Unofficial TWRP Builds

Universal build for m7/m7wls/m7wlv
This universal (unified) build checks the device’s MID (Model ID) during init and applies a device codename based on its findings: PN0720000 → m7wls; PN0731000 → m7wlv; (all other cases) → m7.

Standard builds for m7wlv
