    Can you enter the UEFI/BIOS or it won't boot OS?

    Did you try the procedure outlined here?
    ASUS T100TA BIOS Recovery

    It seems that I've found a way to launch UEFI BIOS Recovery process on the T100TA. Here is what you need to do:

    1. Download the latest BIOS version (313)
    2. Format a USB stick as FAT32
    3. Copy T100TAAS.313 to the root of the USB disk and rename it to T100TA.bin (T100TA has to be uppercase, the extension needs to be lowercase - this is very important)
    4. Connect the keyboard, insert the USB stick into the dock USB port
    5. Make sure the tablet is plugged in (otherwise the flash tool will show an error)
    6. PRESS THE HARDWARE START BUTTON on the left side of the tablet and without releasing the button power on the tablet by holding the Power button for ~2 seconds
    7. When the camera indicator lights up, release the start button and wait
    8. After several seconds you will see the blue screen of the flash utility

    I have just tried it on my working T100TA, and I was able to reflash 313 with no issues. Reflashing this way resets NVRAM as well.
    My Manual calls it the Windows Button, which is just below the Volume button.

    Google surface mount resistors code

    well i have just found the boardview for this motherboard, have found most of the "resisters" around the flash chip are in fact just soldered on jumpers and they are used by the looks of it to select which flash chip to use (wson chip is on there but it can take a BGA chip insted, could come in handy if you wanted to have 2 UEFI and have a switch to select which one you wanted), so just need to solder in place some wire and all should be good
