I tried to update my Hi8’s bios to the dual boot one and the application shut down the tablet right after it finished clearing the bios boot section. Now it doesn’t power on or light the leds when connected to the charger.
I have already received a CH341a usb programmer, SOIC8 clip and 2-channel bi-directional logic level converter but I just don’t know how to hookup the LLC, some people were successful in flashing a 1.8v chip with a 3.3v programmer but since I have the converter I don’t want to take risks.
