The OnePlus 8T is encountering issues updating past Android 13, resulting in frustrating update errors for users. Log entries reveal a consistent discrepancy between the expected and calculated SHA256 hash of the boot partition during the update process. This indicates a problem with the update payload itself or potential modifications to the source partition.

The error messages suggest that the delta update might be incompatible with the current system version or that the boot partition has been altered after installation. This can happen due to various factors, such as improperly installed custom ROMs or modifications to the system partition.

The critical consequence for users is that devices without a supported TWRP (Team Win Recovery Project) recovery solution are effectively locked into this older Android version, preventing them from receiving future updates. This lack of update access leaves them vulnerable to security risks and misses out on new features and bug fixes.
