Flash the firmware
– In recovery, select “Apply update from USB” or “System Update”.
– Wait for the process to complete (do not cut power). Go to Settings > System > About Tablet

Difficult Recovery: If the unit bricks (often due to changing factory settings like camera resolution), finding the correct flash files can be extremely difficult because manufacturers rarely provide them directly.

The Process:

Step 1: Install Drivers Disable Windows Driver Signature Enforcement (Shift + Restart > Troubleshoot > Startup Settings). Install the SPD Driver folder. If you skip this, the PC will not see your bricked unit.
