  • Clean flash is recommended
  • 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 android 12 builds
  • 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.
