Can’t Install CopperheadOS from Android 13 to Android 12.
by Diljot | Oct 20, 2022 | News
Warning: The Android 13 update for Pixel 6, Pixel 6 Pro, and the Pixel 6a contains a boot-loader update that increments the anti-roll back version for the boot-loader. This prevents the device from rolling back to previous vulnerable versions of the boot-loader. After flashing an Android 13 build on these devices you will not be able to flash and boot older Android 12 builds. For developers who need to develop and test against an Android 12 environment, a special Developer Support Build that contains the boot-loader update should be used.
