Note
- 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 boot TWRP/OrangeFox on PE12.
- If you need to switch to another ROM, format data with PE recovery first, and then install TWRP/OrangeFox in fastboot.
- You can dirty flash from my previous PE 12 builds.
- You cannot upgrade from android 11 directly. Formatting data is required.
