you need to short pins out and use usb burnTool can you take closer picture of the nand chip please or post the type bicause original picture does not open large enough

How do we short the nand chip. Will a screw driver do the work?

[JustMe]

kokoui - soem suggestions a pair if very fine tweezer's or some very thin solder or sewing needle or safty pin something that is not going to bridge other pins to short circuit which could fully brick your device.
