Notes

• 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.

Device Specific Changes:

• Etude kernel: Op.12 No.1
  • Linux 4.9.294
  • Merged CAF tag LA.UM.10.3.r1-00500-sdm845.0
  • DO NOT use another kernel. Just don’t.
• Raised the minimal CPU frequencies for INTERACTION hint
  • reduce jank when scrolling through lots of images and videos
• Enabled haptic feedback when pulling down notification panel from the status bar
• Dropped unused entries from mixer paths and audio platform info config
• Many other fixes and improvements from my other android 12 builds

Evolution X Updates:

• December security patch
• Various features are added back gradually

Clean flash guide:

• Install the latest TWRP or OrangeFox
• In TWRP/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. Dirty flash may be fine if you are on my previous Evolution X build.
