Reset Glitch went bad Jasper :::: HOUSTON WE HAVE A PROBLEM

[rroddr]

I have over 5 years experience with xbox 360 repairs, flashing, reflows (hot air and infra-red, Reballing with leaded solder joints, and limited experince with jtaging - about 20 consoles jtagged and 7 reset glitch hacked.

Here is my situation I messed up a customer brought his xbox over to get glitched i forgot about it and didn't test it before I started wiring up the unit I beleive i picked the wrong jasper nand option on the jtag tool. I tried reverting the nand back to the original that I dumped and that was an epic failure I also tried a nand from the other jasper 256 nand that I reset glitched today with no luck.. what can I do would a donor nand help and if so can someone help me out??? also forgot to mention the guy just told me today before he brought it to me it failed an update when he put nhl 12 in the unit...

Use any jasper donor ecc to get ldv of fs 07 from xell. Create fb starting from any jasper corresponding to ur nand size fixing only ldv found in xell.

I can't boot into xell at all just a black screen i used the ecc off of the other jasper that was here to put an original nand on it i got 3 rrod- 0022= usually bad fnand flash
I put xell.ecc file on it black screen.

if it does not work with an ecc donor, which u know worked fine, then there's something else..
