Google Pixel 6 series phones bricked after factory reset

Multiple Google Pixel 6-series devices (6, 6a, 6 Pro) are being bricked after factory resets, displaying a missing 'tune2fs' error and entering a recovery loop that cannot be resolved due to OEM lock restrictions; attempts to sideload updates fail mid-process. While some affected users were on the Android 15 beta, the cause is undetermined; Google has acknowledged the issue and is investigating, and users are advised to avoid factory resets and maintain backups. A previous January 2024 update also caused widespread usability issues, highlighting ongoing stability problems.
