2. Why Perform a Full Update?

A full update (also called a "format all + download" or "factory firmware restore") is not the same as an OTA patch. It is required in the following scenarios:

Boot Loop: The unit hangs on the Android logo or car manufacturer's boot animation.
System UI crashing: Constant "Unfortunately, Launcher has stopped" errors.
Touch misalignment: The digitizer registers touches 2cm away from the actual press.
Lost IMEI/Bluetooth MAC: Can’t connect to OBD2 dongles or hands-free calling fails.
Corrupted MCU settings: No sound, no steering wheel controls, or reverse camera static.
Upgrading from Android 9 to 10 (rare but possible) – requires a full flash, not a zip update.
