Correct Version: Always ensure the flash file exactly matches your device model and hardware version. Flashing the wrong version can cause permanent hardware failure.
Avoid "Format All": Using the "Format All + Download" option in the flash tool can erase your phone’s unique IMEI and serial numbers. Use "Download Only" whenever possible.
