TWRP 2.8.4.0 is out now for all currently supported devices.

What’s new in 2.8.4.0:

  • Add flashing of boot and recovery images via the TWRP GUI (Find the Images button on the Install page)
  • Fix some MTP related crashes and bugs
  • Eliminate TWRP toggling USB IDs during boot if MTP is enabled
  • Fix various adb sideload issues
  • Improve threading of actions
  • Eliminate separate thread for screen timeout
  • Update libblkid to 2.25.0
  • Use power button as back button on watch themes for easier navigation
  • Add mutex locking to data manager
  • Improve custom theme handling on encrypted devices
  • Allow the stock theme to be offset by build flags so we can center a lower res theme on a higher res screen especially for watches with round screens
