It's a Corona V1 16MB
This board has been attempted to do RGH but failed and lost the original nanddump.
Without chip attached, turning on will have start up beep, PSU turns green, fans running, but no dash boot.
So I have tried to follow this guide
https://www.se7ensins.com/forums/th...ing-dumps-erasing-corrupting-the-nand.989323/
to see if it can be saved.
However with the chip soldered on, fake 17526 retail nand Glitch2 ECC written, the debug led will not light up at all.
Wondering what could be the problem?
Have tried two different x360ace v3 boards, factory timing;
Have tried both the bottom POST and the POST on the Postfix adapter;
Have tried both the R4P4 and C5R11 RST pad.
Postfix adapter seems to be fine verified by multimeter, resistance value is about 13K in 200K range.
The chip board gets 5V and GND fine.
No visible damage on the motherboard.
It is obviously the bottom POST has been attempted to solder on but failed, so the previous user installed the postfix adapter to use that post point instead. However when he tried to install the adapter, he also tried to solder the adapter to the pads on the capacitor, which might have damaged the capacitors (Tested with multi-meter and they seem to be fine).
What would you try?
Try remove the postfix adapter? Might time to take out my hot air gun.
