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.

PixelExperience 13 BETA: Official Polaris Build 20220914-1603

- Note: I just realized that the official build is missing a script that bootstraps the dynamic partition. For now, please sideload this [unofficial build](https://drive.google.com/file/d/1gW6g3-l_oQMWTLVf16-vahelSg-Zyj3F/view?usp=sharing) first, and then sideload the official one. This will ensure the dynamic partition metadata is created correctly.

Initial android 13 release. Counting from android Oreo, this marks the 6th major android version polaris has been through. Let's see how long I can keep it alive :)

- 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 cannot upgrade from android 12 builds. Formatting data is required.

PE recovery flash guide
- Download PE recovery from the official PE website
- Boot your phone into fastboot mode. You can either
* hold power + volume down button
* or adb reboot bootloader
* or use the Reboot to bootloader option in TWRP/OrangeFox
- Connect your phone to a computer
- Run fastboot flash recovery pe_recovery_file_name.img in your cmd/powershell/terminal
- Hold power + volume up to boot into recovery

PE 13 flash guide
- Boot into PE recovery
- Select Factory reset" --> "Format data/factory reset. You phone should say that /data, /cache, and /metadata have been formatted.
- Go back to main menu and select "Apply update" --> "Apply from ADB"
- Connect your phone to a computer
- Run adb sideload pe_rom_file_name.zip in your cmd/powershell/terminal and wait until it finishes. It is normal if you see "Failed to find payload_properties.txt" error. Ignore it.
- Reboot to system

Device Specific Changes:
- Etude kernel: Op.13 No.1
* dropped system and vendor fstab entries from dts because they are moved to ramdisk fstab for dynamic partitioning.
* Linux 4.9.327
* DO NOT use another kernel. Just don't.
- Switched to retrofit dynamic partitioning
- Mount /metadata during first stage init
- Pre-optimized SystemUI for speed
- Adapted to the new AOSP BT stack and added several fixes
- Properly enabled thermal pid feature 1.0 for Pixel thermal HAL
- Upstreamed Pixel power HAL to the latest android 13 tag
- Updated DPM, IMS, RIL, and WFD system blobs from LA.QSSI.13.0.r1-05300-qssi.0
- Added a shim to fix an ABI change in libpiex for camera blobs
- Switched rounded corner overlay to vector drawable because Google broke the plain radius-based overlay
- Other misc fixes for android 13

ROM Update Highlights:
- Initial BETA release for Pixel Experience 13. There may be minor issues, and we are working hard fixing them.

Known Issues
- Qualcomm's WiFi Display (WFD) works fine. However, if you have a saved WFD connection, you may see the screen cast logo appear in statusbar after a reboot. Just press disconnect from the screen cast QS tile if that happens. I suspect it is a glitch in the early version of QSSI 13 WFD blobs that we are using.

PixelExperience 13 / 13 Plus: Official Polaris Build 20221122-0804

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.

PE recovery flash guide
- Download PE recovery from the official PE website
- Boot your phone into fastboot mode. You can either
* hold power + volume down button
* or adb reboot bootloader
* or use the Reboot to bootloader option in TWRP/OrangeFox
- Connect your phone to a computer

- Select Factory reset" --> "Format data/factory reset. You phone should say that /data, /cache, and /metadata have been formatted.
- Go back to main menu and select "Apply update" --> "Apply from ADB"
- Connect your phone to a computer
- Run adb sideload pe_rom_file_name.zip in your cmd/powershell/terminal and wait until it finishes.
* It is normal if you see "Failed to find payload_properties.txt" error. The issue has been fixed in this month's release. You will not see it in the next update.
- Reboot to system

Device Specific Changes:
- Etude kernel: Op.13 No.2
* Linux 4.9.333
* built with the latest LLVM Clang 15.0.2 and full LLVM binutils, including the LLVM integrated assembler
* added time slice duty cycle in wifi_interface_info to address the log spam in android 13's WiFi HAL
* added a backport of EROFS from 5.10. Currently nothing is using this filesystem, but we might use it in the future.
* updated to the latest mainline exFAT driver
* fixed a mismatched bound in qcacld
* backported and enabled DWARF5 debug symbol for the kernel build
* fixed crypto assembly for LLVM IAS
* DO NOT use another kernel. Just don't.
- Enabled zygote critical window
- More fixes for the new AOSP BT stack
- Some updates to the USB props and default USB device name
- Disabled advance network scan because our device is a legacy target
- Enabled and configured main and telephoto cameras for the Aperture app

ROM Update Highlights:
- November security patch
- Face Unlock is back
- Translation updates
- The Plus edition is back. Perhaps not all customization options are here yet. They will be added in future releases.

Known Issues
- Qualcomm's WiFi Display (WFD) works fine. However, if you have a saved WFD connection, you may see the screen cast logo appear in statusbar after a reboot. Just press disconnect from the screen cast QS tile if that happens.
- If you enable bubble for the built-in Message app, the translucent background may flicker when the bubble is activated.
- Carrier video call may be broken for some carriers. Please disable this feature on your SIM card settings page if your carrier is affected.

- Override Pixel thermal HAL service initialization to fix boot issues after android 13 QPR1 merge

Evolution X Update
- The ROM has been rebased on top of android 13 QPR1 with December security patch. QPR1 is a relative big change. Features are still being worked on, and not all things are fully stable yet.
- EvoX switched to a source built launcher because Pixel launcher has been having random stutters and battery drains since the launch of Pixel 7 series.
- Other fixes and improvements.

Known Issues
- Qualcomm's WiFi Display (WFD) works fine. However, if you have a saved WFD connection, you may see the screen cast QS tile getting stuck at enabled or disabled state. Forgetting this WFD connection and re-connect should help fix the issue.
- If you enable bubble for some apps, the translucent background may flicker when the bubble is activated. The flicker seems to be slightly better after QPR1, but it definitely still happens.
