Hi thank u for answering that question my problem is that every thing I try I can't get the nand to come up I know that non of my wires are touching I've re solder them like 6 times and I've done this before with no problems here's how all of this started about 2 weeks ago I GOT this xbox worked fine took it apart to jtag it its a xenon so as I was taking it apart I NOTICED the xclamp screws where really tight so i TOOK off the xclamps and the CPU and gpu solder all the wires read the nand with with problem then i wrote xell with jtag tool no problems then i GOT ready to get CPU key put heat sinks back on to get so i could turn it on I NOTICED there was dry flux there both chips so it must have been reflown before so i turn on xbox 3 red light think it was 0110 can't remember so i try like 3 times just to let it over heat see if that would fix the code nope so after that the next day I plug in the console to see if maybe hoping it would turn on it wouldn't even turn on think code was 0001 so i keep hitting power button it would try to turn on then shut off so finally after I keep hitting power button I GOT to get it to turn on i didn't fix anything it decide to turn on still 0110 so after all of this i know this isn't the right way to fix it but when out and got a heatgun so i heat gun it I I DID it once got same error so i DID it again takes like 20 sec then the 0022 comes up so i looked up the code and it says one of the reason for this could is xell so it says to flash your nand back to stock so that's what I'm trying to do but it won't let me I do notice when I hit read nand in jtag tool my power supply seems to like something is drawing power when i am trying to read nand I am using falcon ps on xenon but this is where I'm at there is a scratch on back of board will post pic but its not deep and I know the nand is getting some sort of power cause I could short it out but that didn't help either could this be a pb issue or mosfet or those 4 black chip things on back they had supper glue all over them I GOT most of it off thank u for your help if u HAVE ANY ideas.

If your errors have popped up 0022 and 0110. Its def your gpu. The fact its spitting out a 0001 and those msgs say its your power brick try another one it u have it. Also where u scraped of the glue look for missing capacitors. Usually itll be on the gpu itself to give your tht problem. Also try losening your bolts again. I recomend one type macine screws M5-.8mm from home depot you cant over tighten them. My thought is its a capacitor. But then again your nand should always read so it can be the power brick. Hope it was some what helpful
