The update BIOS tutorial is as follows:

1. First, plug device into the power cord and charge;
2. Right-click the [01_start.bat] file, select [Run as administrator] and click;
3. The device will then update the BIOS (no operations are required during this period, it will automatically shut down after the flashing is completed);
4. After the device is turned off, wait for 10 minutes and then press the power button to turn it on (after the flashing is completed, the first boot time will be long, so players do not need to worry);
5. After entering the Windows interface, flashing is completed!
