What to do after flashing Android 13 on Pixel 6

With Android 13, Google has done its job so that the Pixel 6, 6 Pro, and 6a are Cannot reinstall Android 12 In order to address a security issue. When this vulnerability is addressed, another issue may appear, and Google has issued instructions on how to avoid hacking your device if you have flashed Android 13.

What’s different about Android 13 update for Pixel 6

There is a vulnerability in the previous bootloader in the Pixel 6 series, and Android 13 is making it so that the vulnerable version associated with Android 12 cannot be reinstalled.

However, even after flashing the Android 13 factory image – which is different from OTA image sideloading – On Pixel 6 series and updated successfully, Android 12 version is still on your phone. This is due to Android A/B system updates (seamless)which aims to provide redundancy:

A/B system updates use two sets of partitions referred to as slots (usually slot A and slot B). The system operates from the current slot while the partitions in the unused slot are not accessed by the operating system during normal operation. This approach makes updates error-resistant by keeping the unused slot as a fallback option: if an error occurs during or just after an update, the system can roll back to the old slot and continue to run with the operating system.

As such, “the inactive slot contains an older bootloader whose anti-rollback version has not been increased.” Mismatches can cause problems if you flash your device and something fails to install. By design, Android will attempt to boot from the inactive slot, but this goes against the vulnerability protection. Since it’s Android 12 (and older bootloader), your phone won’t boot.
