Following the guide after flashing the new bios from U disk my w4s not booting anymore, please help !!! 🙁
Dear friend ,are you sure that your device is powerd？
Later I discovered actually display is not coming after BIOS update (only black and white texture fading and coming), rest are OK. It’s booting into Android or Windows. Might be viewable using HDMI cable on a TV which I don’t have right now. Also I don’t have old BIOS backup. 🙁
Please provide the stock bios with flash tools..
