PixelExperience 12.1 / Plus July Update Beryllium



  • Rom Side Changes:

    • July security patch
    • The system updater app will free up its storage after OTA
    • Fixed the issue of Google’s SystemUpdate constantly retrying in the background, draining battery and building heat.
    • Updated lots of APNs
  • Etude kernel: Op.12 No.4:

    • Linux 4.9.322
    • massive backport of the kernel random number generator stack from upstream common kernel
    • fixed several conflicts caused by the random stack backport
    • disabled qcom’s early random initializer because it is no longer needed
    • use ascii-armor canary to prevent buffer overflow from overwriting canary in fork
    • Wireguard 1.0.20220627 to go with the new random stack
    • fixed several section mismatches in qcom’s regulator drivers
    • fixed an incorrect asoc bound check that potentially causes echo in speaker-mode phone calls
    • DO NOT use another kernel. Just don’t.
  • Device Side Changes:

    • Moved the fingerprint HAL process out of system-background task group for cpuset
      • this should significantly reduce the fingerprint unlock latency in some cases
    • Corrected the audio HAL service name in power HAL’s restart script


  • Force Encryption is Enabled by Default.
  • You can dirty flash from my previous PE 12 / 12.1 builds. You can dirty flash the Plus edition on top of PE 12 / 12.1 regular builds.
  • You cannot upgrade from android 11 directly. Formatting data is required.
  • Clean Flash is MANDATORY if flashing for first time!
  • Any Recovery present will be overridden by PE recovery in order to make OTA updates work as other recoveries currently doesn’t supports Decryption!
  • Encrypted users are RECOMMENDED not to use Custom Recoveries! Or else OTA won’t work and have to update manually through adb sideload or external storage.
  • If you are a decrypted user flash Latest TWRP again and follow the steps to update ROM manually.
  • OTA doesn’t work for Decrypted Users
  • Flash Latest TWRP first before proceeding for installation!
