You may have to do a 5v mod in order to flash your original nand.

 

[Scrufdog]

search around for the method to erase your nand. there are a couple ways depending on how bad it is.

i have found the 5v mod for xenon motherboard but not for jasper

You can also do the screwdriver method to short the nand into emergency mode

should be able to wire nand-x and just flash it. I flashed a xenon nand to a jasper once. Just wire it up and reflashed an older image.

treid many times it says it cant find nand controller etc

2nd point, that you cant find is GND so i believe you can use any GND point on motherboard, but it would be good that someone more experienced would confirm this.
I might be mistaken.

The other point is just GROUND. Use whatever gnd point you want, fx a metal chassis peg.

Note its much safer to use a 5v mod than messing around with screwdriver trying to short nand. Only do that as a last resort

Check your wire connections

Depends if you cleared the SMC cache between attempts. If you did it without removing the PSU, you'll be fine. If you clear the SMC cache by unplugging the PSU for 20+ secs, the SMC will attempt to be loaded into the southbridge the next time to reconnect PSU and due to it mismatching, the southbridge won't be able to perform any functions.
