Hey guys... Have a falcon (Was RGH1) that I gave to my brother last year for Christmas. A couple weeks ago, I decided I wanted to give him a Kinect for christmas this year, so I wrote a mem stick with the NAND update to current (I think he was on 16202 or something)... Anyway, he never picked up the mem stick, so I suppose that's a moot point to a degree. Anyway, I contacted him to send me the serial number of the machine, and the CPU key (I like tracking down orig firmwares based on CPU rather than serial as ive a few units pass through in the wrong cases)...
Anyway, I know for a fact it worked before thanksgiving... Anyway, a few days later he contacts me saying it turns on but never boots. I suggested he try booting to xell, he let it run for 5 hours, no boot. I asked if he updated it or something.. he swore up and down he didnt...
So, I got ahold of it. The chip flashes green like its attempting to glitch, but I cant get it to do anything at all.. As I dont know if it was really updated or not, I tried creating a RGH2 ecc and rewired the chip for RGH2. (And set the CR JP1 to open)... Now, when trying to glitch, the green pulse flashes VERY quickly (well under half a second long) but still at about a 5 second interval.

I guess question being... Given that I have the CPU Key, and a clean dump of the original nand (I think dash 9199), but cant boot to dash or to xell to update, what is the BEST method to bring the machine to a bootable state? Im not sure that when I built the retail nand in JRunner, it's what I wanted to do to bring it up to date. And without knowing for sure wether the machine was truly updated, I dont know what the LDV should be set to..

Anyway, any suggestions would be great.

as in, did i remove the physical part of the board to stop efuses from tripping (I forget the exact location's name).
The answer is no.
It was one of the very first machines I had ever glitched, and I didnt know any better back then.

You may have a genuine RRoD.

Just write back ANY valid image to the console. The original dump you had will do. If you get an RRoD within 10 secs, it's hardware. A CB/CF/CG mismatch will take at least 3-4 cycles (15-20 seconds) to RRoD 0022. Get the secondary code too.

OK, THIS is interesting (And I can only assume that part of the reason it didnt work the first time was my faulty cables)... BUT, Wrote the original nand to the machine and bam... booted no problem (Chip is in PRG mode)... but, the odd part... When chip is on and ECC is written, the CR only blinks once then nothing and the machine doesnt boot. CR continues doing nothing while the front green LED keeps blinking (No DVD drive in).
I hadnt touched the wires from the original RGH install, just added the RGH2 wiring and removed wire A from coolrunner to try RGH2, then removed RGH 2 wiring when it booted to original stock...
Ive never heard of a coolrunner chip going bad... is it possible?

So it's booting with the 9199 image? First thing to do then is protect the efuses to stop any unnecessary LDV changes.

next, rewire for RGH1 and retry.

Yes, boots to 9199, but when I write the ECC for RGH1 and have it wired for RGH1 and timing files for Falcon RGH1 all the chip does is blinks once, then nothing (still sounds like it's cycling)... but never boots to xell... Weird

Im gonna try pulling out all of my wires and redo the whole thing.

Interesting... It works fine now... Same old Coolrunner that was in it... Must have had a cold solder joint with my old wiring... (Looking at old work, it didnt look like i used much flux, or maybe used a liquid flux... versus using a paste flux like i do now)..

Anyway, Thanks a billion Martin C, dont think I would have fixed it without a few suggestions from you :)
