My 360 was in pretty bad shape, fried nand flash, and everything looking like a mess inside.
I sent it to uN0pEn and all was taken care of! It did take a couple days longer than expected, but when I got it, hooked it up, it worked perfectly.
All things ordered:
Nand flash (had to desolder my nand and onto another board)
3.5" Hard Drive SATA & Power Cable MOD
btw, uN0pEn did a VERY good solder job, I got in there a week or so to add an extra fan, and I was tugging on some of his solder points pretty hard and they didn't even budge.
Now I got my 360 with a 1TB 3.5 inch connected Thanks!
