    Hey guys, I managed to brick my bios. I tried to install new BIOS, but i chose bad version. My tablet has A5C6 and i tried to install a5c8. Any idea on how to unbrick it ?

    I did exactly the same thing, and had to send the tablet back to China so it could be reflashed. (-_-)

    Thanks for reply. How much did the reflash cost ? Do you think I could somehow blaim it on “bad windows update”or something like that 😀 ? Or would i have to cover the costs ?

    You have to buy a CH341a programmer with a clip and reflash the chip manually from a PC. No need to remove BIOS chip from tablet but you have to desolder battery pins.

    There is a post in this forum about BIOS mod where I tell my (successful) experience reprogramming BIOS.

    Did you tried to change bios settings in order to activate OTG Charging and other stuff?

    You have to open physically the tablet and reprogram BIOS flash chip with a flash programmer and a clip. It’s not very expensive. About 20-30 USD/Euro.

    Yes. In fact only unlocking hidden BIOS settings to test from BIOS menu.

    I have a similar situation.

    I’ve received an A5C8 versión from banggood. In BIOS Setup, it said tPad 1.02 version, and in CPU-Z, it said the BIOS was from January 15th 2016.

    So I downloaded that 15GB pack that there is over there, to convert A5C6 into A5C8, extracted  the BIOS update folder, copied to C: drive in the tablet, charged the tablet up to 80% at least, and began to flash it. Procedure was OK, flashing showed PASS in big ascii drawing.

    After that I tried to restart the windows, and the tablet in the turning off process, began to install windows updates… The it switched of, and I cannot power it on again…

    Is there any solution? from then it’s charging till it gets 100% battery.

     

    Saludos.
