    Great… So there is no way to make the keyboard working on V4.5. V5 bios wont work either? Think not if V4 bios works on V5.

     

    But V3 has same bios tag… I had V3(?) before V4.5. It got bad touchpad and no ssd slot, but ac-wifi and fast emmc.

    @Juha Pirinen, could you upload your bios, i made a collection in this thread: https://techtablets.com/forum/topic/v4-or-v5/ and would like to add the v4.5 as well. BTW mine is a v6 BIOS from 05 Dec 17.

    Got the CH341A programmer at last… Put my original.rom on the chip with the programmer, verify goes ok but still black screen.

     

    And now I have a feeling that I have tampered the wrong chip ALL THE TIME! This 25Q80C chip has 1 meg of memory and all the bios files are 8 meg size. The other chip is GD25LB64CW1G and it has 8 meg memory.

     

    GD25q80C is located near ITE-superio chip and the GD25LB64C is near CPU.
