Saturday night my friend calls me up and since he is getting RRoD so I told him to bring it over. Hooked it up and sure enough there it is, 3(1,2,4) blinking red lights as soon as I turned it on. I've heard alot about it and read a the RRoD was the worst game off all time in Game Informer(They called it: Living on Borrowed Time) so I figured I'd tackle it for him since he used to let me share off his internet. Went online and read a few articles about how to fix it and took the majority of advice from xbox-scene to tackle this issue. I wish I took pictures of this cause something was very disturbing after I popped his 360 open and took off the GPU heatsink...there was thermal paste ALL OVER the GPU, not just the core, I literally mean ALL OVER! Tools used: 8 5mm .80 x 10 bolts 16 #10 nylon washers 24 5mm steel washers Kobalt torx driver set..$5 bucks at Lowes 5/16th socket and wrench Small straight head driver Crescent wrench 13/64th drill bit + Drill Here is a quote and awesome info from mlee49: That'll work for about 50% of the 3RRoD occurances, but you'll need to take further measures to permanetly fix this issue. I pulled the heatsinks off the gpu and cpu and cleaned both throughly. After clean up I covered the caps and pretty much everything else with two layers of Glad Press and Seal wrapper and then two layers of Aluminum foil. I used a $25 heatgun that I picked up at Lowes(along with the nylon washers and other mounting hardware) to reflow the solder over the GPU, CPU, NB, H/Anna chip. It took 1 minute on low to warm(250C) up and then 4-5 minutes on high(500C) per each side. Circling the chips and going from each chip after about 20-30 seconds. After reflowing the solder I let it sit for 45 mintues and uncovered the foil/wrapping paper and applied new thermal paste the right way. Attached the new hardware using the bolt-through technique and powered on. No more RROD! Most of the time new thermal paste will work + the bolth through but you may need to reflow the solder on the board to permanently fix the issue. Good luck and enjoy fixing your own hardware. You do not have to remove the cpu heatsink since the issue is with the GPU but I decided since I was in there...why not now! Once I had the board out I used the straight head driver to sit on between the lip and top of the X-clamp and so carefully tilted the driver which will make the clamp lift off of the heatsink mount. Once I did this to 3 of them it came right off. Repeated for the other heatsink(Doesn't matter which one you do first). Once the heatsinks are removed take your crescent and remove the clamp holders on the bottom of the heatsinks because this is where the bolts are going to bolt to. The longest part of the job would be cleaning since they use, I swear, super glue and thermal paste cause with just 90% alcohol it would've taken forever to clean the GPU and CPU..but Goo Gone is some awesome shit! I basically just put a little Goo Gone in the cap, dipped a cotton swab in it and rubbed it on and around the CPU and GPU core(Also had to clean the little transistors, or whatever they are called, cause Thermal Paste was all over them). Once I cleaned(should have a almost mirror finish), did the same with alcohol to make sure all the Goo Gone was cleaned off before resemble. Before resembling I took the drill and 13/64th bit and drill the mount holes on the Chassis a little wider so the bolts could fit right through. Once I did that and debured the holes I then took the bolts through the holes and taped them off(I recommend Painters tape or scotch tape which you will see why later). Once the screws are through now take 2 of the steel washers and place them on the bolts on the inside of the chassis and cover with 1 Nylon washer to protect the board..repeat for all 8 bolts. Now that the chassis is prepared lets put some thermal grease on the CPU and GPU cores. I used AS5 but you can substitute with what you have available and put a little on the GPU core, the little chip next to the GPU core that's on the GPU, and on the CPU core(if you are doing this one as well). Once you have the thermal paste on now put the board into the chassis, gently cause you want to make sure the bolts go through the mount holes(you may have to take a pin and straighten the bolts through the holes as you are laying the board in) Once the board is in and laying nice and flat on your washers take 1 nylon washer and place it on the bolt and then put 1 steal washer on the nylon, again, to protect the board. Once you have your washers replaced grab them heatsinks and get your socket and socket wrench ready so we can put those heatsinks back on. If you have ever had to pull a motherboard to install a heatsink, you'll know its best to tighten in a criss-cross pattern. At first your going to go slow and easy, and have some pressure on those heatsinks to make sure the bolts are going through the holes. You'll get to a point were you will start to feel resistance...GOOD! Now tighten in the criss-cross pattern, NOT TO TIGHT, but to were the heatsinks aren't wiggling around. BEFORE TURNING ON MAKE SURE DVD-ROM DRIVE IS PLUGGED IN Plug the fan and DVD-ROM drive in but I recommend, makes sense, to place the fan assembly over the Rom drive were one fan is cooling the CPU heatsink. Now plug in your AV cables, so your not getting the 4 RRoD, and the power supply and fire that baby up What's this...3 RRoD still. Yes, that's because overtime the BGA's on the GPU may have become undone but what we are going to do is try to get them back in place which is why I stated the way you should have your fan plugged in. Now let them system run for 15-20 min flashing the RRoD. You may notice over the time frame it will start to flash only 2 lights which is a good sign, or just keep on flashing the 3 lights. Once the 15-20min is up turn your 360 off and let it sit for 10-15min. Turn it on You may already have your 360 working again or it might be still doing the 3 RRoD. If you still have the 3 RRoD's don't worry, It took me readjusting the bolts and 3 tries of the turn on 15min, turn off 10min; to get his going again. I will get some pictures up since now he called his friend up and this weekend I'll be working on his but it only took almost 2hrs of my time so no big deal.
