    Hi!!

     

    I have a Onda V919 Air 3G dual 64Gb with the windows broken and touching the bios setting i disabled the USB.

    Now, i can boot Android, ADB and DNX but i cant put a keyboard or mouse or USB Pendrive to repair windows.

     

    I have seen the posibility to repair/reflash bios from DNX in the teclast one, but i want to know how to reflash BIOS or to create a Load Default settings to enter again in BIOS with USB support.

    Thanks

    <span style=”text-decoration: line-through;”>I have disbled USB support in bios , and now i can repair windows o go to bios to boot.

    I have ANDROID , adb and dnx but not support to USB…..my win install its broken and i dont know how to set the bios to default values….

    I see the teclast can be flashed via a utility , i have fastboot tools installed but i dont know how to do…</span>

    If you have disabled bios acces to usb , the solution to unbrick the bios an load default values its locate the winbond bios and with a cable atached to ground , pin to pin2(DATA) of the chip 5 seconds after tablet boots, 3 times .

    After this a MMC no bootable media its seen on screen and bios loads default values , you can atach a keyboard an save the changes.

     

    I see this solution in this forum called unbrick nuts or similar…it works for ONDA too!!
