PixelExperience 12 ALPHA 20211031-0531 Unofficial Polaris Build

  • This is an unofficial alpha build, and things are subject to change:
    • Unofficial because official release has not started
    • ALPHA because the source is still work in progress
  • Formatting data with PE recovery is REQUIRED for clean flash
    • DO NOT use any other recovery
    • The firmware is included with a different keymaster.img from perseus. DO NOT flash your own firmware.
    • Keymaster is bumped to 4.0 for encryption, and cust partition is mounted as /metadata. You WILL NOT be able to use TWRP/OrangeFox on PE12.
  • You can dirty flash from my previous PE 12 ALPHA builds.
