More Tiramisu - Android 13 - Pixel 3 - 6a

CalyxOS 4.1 - Android 13 is now available for testing for all Google Pixels.

We’ve done some basic testing internally, and are also simultaneously doing more extensive testing. Based on that and the feedback from testers, we’ll bump it to beta and then eventually stable. Factory images will be available at that time.

Fairphone 4 Android 13 port is work in progress, we hope to be able to release it next week.

We will be revisiting OnePlus devices after that.

  1. Make sure your phone is running the latest stable CalyxOS 3.9.0 - Factory images will be available later. If you’re on the previous test Tiramisu build, you can skip this step.
  2. Go through the Known issues list above, and make sure you’re ok with that
  3. Backup your data - you can use SeedVault, the included Backup app.
  4. Enable USB Debugging on your phone.
  5. From your computer: adb shell setprop thirteen
  6. Then, on your phone: Settings -> System -> System update settings -> Check for updates


Warning The Android 13 update for Pixel 6, Pixel 6 Pro, and the Pixel 6a contains a bootloader update that increments the anti-roll back version. After flashing an Android 13 build on these devices you will not be able to install CalyxOS until our Android 13 update is released.

Please keep this in mind if you have a Pixel 6, 6 Pro or 6a. If you update to 13 at all, either on the stock OS or a custom ROM you should stick to it and avoid trying to downgrade. Doing so will brick your device, rendering it non functional.
