Description of problem:Falcon now wont boot to xell,glitch or boot to stock nand ive written back

Was the console working before you started:Yes


hi guys,here goes.ill try to remember the steps taken
started of dumping nand twice,nands were same.had 1 bad block which jrunner remapped
created and wrote ecc to nand
fitted coolrunner rev c
wouldnt glitch to xell,
MartinC said in irc to put switch to slim and use slim blue wire instead of double shielded cpu rst wire
got xell and copied cpu key
now i think this is where things went awry somewhere
nandump showed dash of 16203
i built glitch image using 16537 dash,rgh2
wrote to nand,

i was concerned about wrong version in jrunner
i tried glitching falcon but it wouldnt for the most part.
glitched twice but took an eternity(over 5 mins)
not sure if blue slim wire was culprit as i dont exactly know where and how to route it
i checked soldering,redid some to try and tidy it up
after numerous nand writes and tests it still wouldnt glitch so i decided to just put stock nand back on
loaded nanddump1.bin and wrote to nand
console wouldnt boot to dash
removed nand and coolrunner wires completely,still no boot
the green light on rf board of xbox was green but no dash
i removed all solder from mobo with solder braid and ill include pics of them.
then falcon started red ring on boot up,0022 error code
i read some of martinC's posts regarding ldv's and wrote a retail nand with ldv changed to 14 to falcon.
booted console and it was green light but no boot or red rings
i dont know what the hell ive done but obviously something has gone majorly wrong :facepalm:
any input would be gratefully recieved
please no flaming of my soldering,its not the best but ive seen worse on here lol

If you wrote back the stock nand you dumped from that console, then I would start by Reflowing/reballing the gpu/hanna/cpu. I had a falcon with a demon installed that would not reset the smc, and would give this error, but since there is no demon installed in this console, I would seriously doubt that is your problem.It could also be a problem with the ram chips.

the stock nand was ldv13,when i made image for 16537 glitch i think it changed the ldv to 14.
the console was working perfectly before i started messing with it

From what I can see the ldv in your stock image has not been changed. I am quite sure it is correct. Cant be completly certain unless you can post all of your xell fuses though, But this sounds like a falcon R-Jtag I did for my girlfriends son. Did the same thing. It stopped working the same day I did the install, With a genuine RROD. I was not very happy considering those qsb's are hard to unsolder.

update...
falcon still wont boot any retail dash!
now boots to xell,all bit it in around 6-8 pulses
still no boot to glitch image,rev c sometimes stops glitching altogether and other times glitches for ages but no boot
cut down slim blue cpu rst cable to 40cm,still no joy

To close this thread, I took a look at the board over the weekend. It most definitely is a CPU issue which has occurred during the attempt of the RGH.

The console gets to POST_68 in the boot sequence (both retail and RGH) and halts. XeLL will still boot.

Thanks to sas67 for letting me have a look.
