I have fixed several 360's with x-clamp fix and reflow. The very first one I fixed just required a x-clamp fix and it has been working since early 2009. Now, abruptly it started up again. I was playing Ghostbusters, decided to watch a movie so I shut it off and watched a movie on my dvd player. I attempted to turn it back on and there is the RROD. I really don't want to open it up again, so I did a little bit more research and I found something where somebody said let the RROD run for 30-90 minutes then turn the 360 back on right afterwards.
So, I did just that for 90 minutes and the 360 turned on to the loading screen only to freeze. I turned it off and back on to reveal the same RROD error again. So, I did it again for 30 minutes, but let it cool instead of turning it back on immediately after but it kept the RROD. So I did it again for 30 minutes and it loaded the loading screen and froze again. I decided to keep the loading screen on for about 10 minutes to turn it off and turn it back on. It kept the loading screen but it only froze again.
I haven't seen or heard about this yet. I'm not quite sure if it is the GPU overheating because it doesn't quite explain why it turns on for a brief moment.
0110 is usually a ram error. If you want to fix it, you're going to have to open it back up. There's a member on here "w00ly". In his sig, he has a video that I think would help you out.
Basically, what you were doing with leaving the console on was overheating it for 30 minutes. That's usually a one week fix if you're lucky. The console doesn't get hot enough to melt the cold solder joints that are causing the RROD. With w00ly's method of fixing RROD's, you'll get the solder hot enough to reflow back into place.
yea the more you keep turning it on and leaving it over and over is only going to make it worse and less of a chance to fix it again. what you are doing is essentially the towel trick without the towels
