Note

• Initial PE 13 stable release. Sorry for skipping October’s release and the absence on forums. I was insanely busy with work and other IRL stuff.
• There will also be PE 12 / PE 12 Plus maintenance builds released in a few hours. They contain the latest November security patch that addresses a severe security vulnerability.
• PE recovery is REQUIRED
  • DO NOT use any other recovery
  • Partition scheme has been switched to retrofit dynamic partitioning because polaris is running out of system partition space. No actual re-partition is involved. Instead, the physical system and vendor partition is mapped together to form a logical “super” partition. The size of super partition equals the sum of the physical system and vendor partitions. After that, logical system and vendor partitions are created on top of this super partition. In this way, we are essentially redistributing space between the physical system and vendor partition to accommodate for the increase in size of system libraries and prebuilt apps.
  • The firmware is included with a different keymaster.img from perseus. DO NOT flash your own firmware.
  • To switch to other ROMs, format data in PE recovery first, and then install another recovery. You may need to re-flash the required firmware, if the ROM you are going to flash does not include one.
• You can dirty flash from the previous PE 13 build. You can dirty flash PE 13 Plus on top of the regular PE 13.
• You cannot upgrade from android 12 builds. Formatting data is required.
