Google Offers Additional Instructions to Pixel 6 Users Who Have Flashed Android 13.
Google has made it impossible for the Pixel 6, 6 Pro, and 6a to reinstall Android 12 with Android 13. This is due to a security problem. Google has provided instructions on how you can avoid bricking your device after fixing the vulnerability.
What’s new in the Android 13 update to Pixel 6?
There is a security flaw in the bootloader used on the Pixel 6 series. Android 13 prevents the reinstallation of the vulnerable version.
An Android 12 build will still be on your phone even after you flash an Android 13 factory picture – which is different from sideloading an OTA image – on the Pixel 6 series. This is because of Android’s A/B system updates which are intended to provide redundancy.
Two sets of partitions are used to update A/B systems. These are called slots. The current slot is used by the system, and the system does not access the partitions in an unused slot during normal operation. This makes updates more reliable by using the unused slot as a backup: In the event of an error during an update or right after, the system can rollback back to the old slot to continue with a functioning system.
