TWRP 2.8.3.0 is out now for all currently supported devices.

What’s new in 2.8.3.0:

  • MTP fixes and improvements - you can now copy zips to the root of storage - thanks to _that
  • MTP will now tell the host PC that storage is removed instead of disabling MTP completely
  • MTP will now report the correct max file size based on the file system in use to the host PC (may fix transfer of large files)
  • Update and improve fix permissions and make fixing contexts optional
  • Update SuperSU in TWRP to 2.40 and update install process
  • Make TWRP work properly on AArch64 (Nexus 9 is now built in true 64-bit binaries and libraries)
  • Attempt to set correct permissions and contexts on all files placed in storage so backups will show in Android
  • Fix kernel panic during MTP start on some devices
  • Support unicode fonts on devices with True Type Font support
  • Fix slider value not showing sometimes (vibration settings page)
  • Toggle MTP off during adb sideload to set correct USB IDs
  • Reduce library requirements for 5.0 L decrypt
  • Other minor fixes and improvements
