I repeatedly solder and desolder the chip and try your bin file over 5 times. But it still failed. no POST comes up. Anyone else can help verify the bin or re-patch the bin for me? Thank you very much....Leave a comment:

after writing the patched file to the chip, and solder it back. Unfortunately, it can not be booted. As long as I press the power button, only the "LED activity light" turn in amber color. No matter with battery or not. Do I need to handle the other chip? Any clues?...Leave a comment:

The software I am using is Neoprogrammer 2.2 which can not detect the IC, from the schematic the chip is named GD25B256DYIG. but actually, it is ?XMC QH64H1Q? nonetheless, i cant see support list.Leave a comment:

I did test them pin by pin, all the pins are independent. By the way, why some other user request, only 1 bin file ok, but I need both? Could you explain a bit more? And I did try to load one of clean 5410 firmware to the main chip and the services tag become 7Y9N273-8CF8 in the bios password screen and I could get in read-only bios while I can't even get in bios when I use original firmware and it shows 7Y9N273-0001.
Thanks a lot.Leave a comment:
