oh FFS stop!
Now I have the history of it, it makes sense.
It was JTAG'd using standard wiring. Therefore you re-wire it as a JTAG to make it work. Flash back the original NAND and it should boot up.
If not, Random E79's were caused by the wiring method, so keep this in mind whether you need standard or AUD_CLAMP wiring.
You do NOT need to RGH this.
