i'm in sorta the same boat.
I'm using this donor trinity nand.
How did you go about rebuilding the original stock nand?
My slim was updated to 13604 before installing CR.
I accidentally overwrote my original nanddump with the nanddump that contains my ECC image. My mistake.
So now i'm trying to continue on with trying to boot into a hacked dash, but keep getting the flashing RROD, and no image from HDMI output.
I'm trying to build an original build so
1) I can flash to slim to see if it boots without CR.
2) Need original nand to build a glitched nand.
I've extracted the KV.bin and SMC_config.bin from my nand w/ecc, and injected into donor nand. Used 360flashtool to insert my cpukey retrieved from XeLL, then took that and ran it thru Multibuilder to build a retail nand.
Then flashed my slim nand thru XeLL (xenon.elf).
Unfortunately i cannot get it to boot in any dashboard. However, Xell I can get into.
I also checked applied my LDV value from Xell into the multibuilder options.ini file.
Any help would be appreciated!
Been working on this for days!
