Hi,Am using matrix nand flasher and nandpro 2.0e, both worked fine on another motherboard.10.83A Power supply showing yellow/orange while plugged in, same power supply worked fine on another console.Trying to boot will only give one beep sound, no sign of fan or any other activity. Have tested all the MOS on the motherboard and the voltage drops seem to be normal, I assume all of them are good.Tested the soldering points for nand reading, against the pads on the bottom side for continuity , all seems to be fine. Have re-soldered them anyway. GND Point has been soldered to the AV port. So what can I do with this issue?I assume the motherboard is alive and I would need to unlock the flash chip by shorting?Have already tried to short the pins using a wire taped to the pins, or a screwdriver, neither worked.Maybe I should try to solder wires directly to the pins? 1) Disconnect Power Cable from 360, and disconnect USB cable from PC 2) Leave 360 unplugged for 2 mins 3) short data pins 29-32 being careful not to touch power pins 36&37 (my screwdriver was actually too big and ended up shorting 27-32 which worked fine for me, make sure the screwdriver head sits flat along the pins so it touches all of them without pressing too hard to avoid damaging) 4) Plug in Power 5) WAIT 5 seconds!!! <--- did not see this in other guides and it helped me! 6) Remove short 7) Plug in USB cable Erase entire nand using the command: nandpro usb: -e16 0 400 Some threads say shorting pins 44-47 instead, so which one is correct?
