Flash the original Global firmware and relock the bootloader. | | Heating/Battery Drain after Update | Normal post-update background optimization | Wait 2-3 Days : Do not panic. Allow the system to idle on Wi-Fi overnight to finish indexing. | | Rollback Failed | Attempting to downgrade a minor version or missing rollback package | Only official service centers can handle this. Trying to force flash a lower version will cause a security verification error. | | Cannot Enter Recovery Mode | Corrupted boot partition or hardware button failure | Use ADB commands: adb reboot recovery . If that fails, flashing the boot partition via fastboot is required. |
