So I fixed my 360's RRoD a few weeks ago. X-Clamp fix did the trick for a little while. Now I got the dreaded E74 error. At first, I got some strange graphical glitches and just figured the system was overheating. So I turned it off. I came back the next day and it seemed to work fine until I started getting these weird graphics again. This time, they came a lot sooner, so I know the system couldn't simply be overheating. I reset the console and was met with E74 error.
I've been researching the error and think I have a solution, but I would like some input. Some guides suggest doing the X-Clamp fix to solve the E74 error. Since I'd already done that, I tried adjusting the tightness of the screws which only ended up causing the old RRoD to come back. I retightened them back to the way I had them before and the old RRoD disappeared again, but it still leaves me with the E74 error.
Further research suggests putting pressure on the HANA chip. I tried doing this manually by turning on the 360 while pressing down hard with my finger on the chip. No luck. I really put some serious pressure on it, so I'm wondering whether or not the so call "Penny fix" would be worth a try.
