Evolution X 6.6 07190900 Official Polaris Build

Linux 4.9.323, massive backports of kernel random generator stack, faster fingerprint unlock, July security patch, battery drain and heat build-up fix, and many new features.


  • Formatting data and clean flash are required if you come from android 11. Please do not update through OTA if you are on android 11.
  • Encryption is disabled for various reasons. You can keep using the latest TWRP or OrangeFox, but please follow the clean flash guide carefully.
  • Dirty flash is fine from previous EvoX builds based on android 12 or 12.1
  • When switching to other ROMs, you may need to re-flash the required firmware, if the ROM you are going to flash does not include one.

Device Specific Changes:

  • Etude kernel: Op.12 No.4
    • Linux 4.9.323
    • 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.
  • 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

Evolution X Updates:

  • July security patch
  • Fixed the issue of Google’s SystemUpdate constantly retrying in the background, draining battery and building heat.
  • Added some new fonts, including NothingDot
  • Toggle to enable adb root
  • Brought back alarm & wakelock blocker
  • Brought back sensor block package list
  • More themed icons
  • Several more QS tiles, including Locale tile and Music tile
  • Misc fixes

Clean flash guide:

  • Install the latest TWRP or OrangeFox
  • If you have the latest OrangeFox R11.1_1, you can simply wipe the cust partition from GUI. With TWRP or older versions of OrangeFox, open Terminal (Advanced/Terminal in TWRP, Menu/More/Terminal in OrangeFox), and run command
    mke2fs -t ext4 -b 4096 /dev/block/bootdevice/by-name/cust
    then enter “y” to confirm.
  • Install ROM in recovery
  • Format data (the one you type “yes” to confirm)
  • Reboot

Gapps, vendor and firmware are included.
