The BIOS update tutorial is as follows:
1. First, plug the device into the power cord and charge;
2. Right-click the [01-start.bat] file to run as administrator;
3. The device will update the BIOS (no operation is required during this period, it will automatically shut down after the flashing is completed);
4. Wait for more than 3 minutes after shutting down the device, and then press the power button to turn it on (after the flashing is completed, the first startup time will be longer, players do not need to worry);
5. After entering the Windows interface, the flashing is complete!
