I thought I'd post on RSOD fix as I have personally been plagued with this problem for a while and with help from Susoft I was able to fix it.
History: I had a CECHG01 on 3.55 firmware that I purchased with RSOD. I used the "RSOD Fix Factory Service Mode tool" from the scene with success.
I upgraded the firmware to 4.31. All was good for 3-4 days. Then RSOD again. With the console on 4.31 my options were limited to a Flasher. I was able to use an e3 flasher to get many perfect dumps. I forwarded the dump to a scene member by the name Susoft who was able to inspect and fix the dump. I am not sure how Susoft found the problem or how he knew where to look but all credit for the fix goes to him.
So here is how I fixed RSOD:
1- Get valid dumps using any flasher.
2- Compare all dumps make sure they are all the same.
3- Send dump to Susoft for repair. (maybe he will make a tutorial on what to look for)
4- Check the returned dump
5- Flash the fixed dump back to the console.
I don't take responsibility for any of this as I am new at flashing and cannot guarentee that your dumps can or will be fixed.
I have attached a pic of my original dump and the fixed dump. It is byte reversed as it was done with an e3. That was the only line that was fixed by Susoft. I flashed it to the console and the console is working fine. I also downgraded it to 3.55 without problems.
