Hey guys, been quite some time since i've been here, how is everyone?

I recently got ahold of an older 360 that was RROD, I believe it to be a xenon board, I had gotten it to work, and it has a pretty old dash on it, 5878 I believe it is, and since i've not done anything with 360's in quite some time i've been researching the jtag bit of it and i'm assuming from what I see, this is a good thing? Well I've dumped the nand and try to load it in degraded (which i'm not really sure I need to) but it will just load everything blank or crash. I'm at a loss with it, I thought it was due to windows 10, but tried on 7, virtual XP, and XP, but just seems it would rather crash than load anything.

Is it due to the version of nand, windows, the dump? Anybody have any ideas whats going on??

Btw, I used a usbjtagnt for the whole bit.

Thanks much! Very Happy

Well upon more searching for why the degraded keeps crashing, i found this on another forum:

Quote:
Degraded instructions
Open it, then go to setting then under 1BL key put

DD88AD0C9ED669E7B56794FB68563EFA

then check the valid box.

At the bottom where it says file system start, put 39 then hit OK. Your NAND should now open in degraded


Which did stop it from crashing, and loaded the nand image i had dumped. Degraded returns this info:



Now by the looks of this, and what I have been reading, this should be exploitable, correct?

Got it all sorted out, turns out I was using the wrong program and forgot to put in the diodes on the MB. Got the nand flashed back to the console and running Xell Reloaded and Dash. Now to learn what its new potential is!
