Short-Circuit: Disconnect the battery. Plug in the prepared USB drive. ⚠️ Important:

Use a screwdriver or conductive tool to short-circuit the specified pins on the eMMC. Turn on the PC while holding the short-circuit. Once it boots to the USB, remove the short-circuit tool. Run the BIOS flash utility from the USB. Method 3: CH341A Programmer (Hard Method) If the above methods fail, you must use a CH341A SPI programmer
