asus T100ta tablet pc bios help needed


Hi. I have a problem. My asus t100ta tablet pc bios deleted. It couldn't boot. I must write it again. I found dump. But need spi flasher. I think we can write bios chip with z3x jtag. It's winbond W25Q64 8m chip. i found on board tp points but they are called DO, DI, CS. How can we do it with Z3X jtag? Any opinion?

i think you do not need to use the adapter use the jtag cable directly and if you use the adapter you do no need to supply it with power

If you use EasyJTAG box 1-st generation (old box), you need make 1,8/3.3 power supply adapter (from RJ45 or USB)
