Anti-rollback mode: after upgrading the official version of Android 13, Google Pixel 6 + 6 Pro / 6A no longer supports flushing back to the old Android 12 operating system.

CTOnews.com August 16 news, starting today, Google launched the official version of Android 13 for Pixel phones. This Android update further enhances the Material You theme introduced in Android 12, improves existing privacy controls, and introduces the ability to copy and paste on supported Android devices. "the official version of Google Android 13 has been released, starting to push to Pixel mobile devices (with updated content)"

It is important to note that Google Pixel phones (using custom Tensor chips)-Pixel 6, Pixel 6 Pro or Pixel 6A-will not be able to flash back to Android 12 after upgrading to the official version of Android 13. Google developer website notice shows that this is caused by the boot loader update.

"warning: the Android 13 update for Pixel 6, Pixel 6 Pro, and Pixel 6a contains a boot loader update that adds anti-rollback versions. After you flash the Android 13 version on these devices, you will not be able to flash the older Android 12 version."

In addition, if the user has participated in the Android 13 Beta test and wants to exit the quick update cycle without erasing the device, now is the time. After updating your phone to the latest version of Android, simply visit the Google Beta website and unregister. On the other hand, if you stay in Beta, you will be able to get a test version of the new features of Android 13 in advance.
