well little update... it´s been a long day... i didn´t go to work, today because i have flu. So i spent the whole day with the 360.
This is the story. Yesterday after my 1st boot i got my system freeze at the intro.... no red lights, just freeze.
So i did the overheating, this time i did it corrrectly, took around 4 min to overheat and after that i left it until the psu went orange (4 min).
I guess those 4min wasn´t enough. But also.. i remember i didn´t tighten the screws, because again i was really scared of broken or damaging the cpu/gpu.
Anyways, after tighten the screws a bit, not much just a tad.. and doing the overheating.. i was able to pass the xbox intro, i left the xbox on the dash for around an 1hr and everything works fine.
I went to bed very happy..
Today i got up, i tried a game,to make a real test on the system, i left a demo game for around 15 min.. but after 5 or 10 min into the game, the system froze... i couldn´t pass 10 min without freezing the system.
There was a problem...
i tried to ran the demo a few more times, and same results, the demo froze between 5 to 10 mins.. After my 3rd attempt i got the 3rl again.. (this was the first time after doing the x clamp replacement). Same code, 0102.
At this point i remember someone who said that he did the towel trick after doing the X clamp to help soldering those lose transistors, because the 2/4 min overhating technique wasn´t enough for his system. So i took 2 towels and did the same thing.. i left it for 20 min.. after that, i left the system cool down... and i re open the system and tighten the screws, but this time i did it really tight.. i even put some pressure on those bolts.
then i rebuilt the 360 again and tried.. so far so good.
i left the demo for around 30 min, no freezing (before i couldn´t play it for more than 10 min before).
then i turned the system off for 2 min, and turned back on, again , played the demo for 30 min.. no problem.
After this i turned the system off... and wait a few hs.. then i turned the system on and played virtua tennis3 demo por 20 min.. no freezing either. After this i played condemend for 30 min.. no freeze.
So i end up playing the system for 2hs total... and the system didn´t freeze, no red lights either.
Maybe is luck, but since i wasn´t able to past more than 10 min without freezing.. i guess i may did something right.
I don´t know if the problem was the system still got some loose soldering... or, if the bolts weren´t tight enough, or maybe both... but so far the system is working...
i´m wondering for how long....
btw i added 2 more coolers.. 1 on the sides throwing freesh air to the system and 1 on the back helping the stock fans to take the hot air outside the system. both at .12v
tomorro i´ll do some more testing but if i finnish the day without a problem, then i´ll be able to say my system is working again.
Well I'm glad yours is working, So I have now fixed 3 360s so far, and two outta of 3 have had the same problem one was using RBJTechs method and one was using Lawdawgs. I had a bear of a time getting the one I just fixed recently to work, because every time i would make it "snug" I would get graphical freezes, so I did exactly what you did, overheat and tighten them down
, now not so tight that like the board was about to snap, but that the nuts would not move unless you forced them. This solved the problem, and my friend who performed Lawdawgs tut, started doing the same thing, he tightened them down again tight enough that the bolt would not move unless you really forced it too. I'm happy to say both are working fine now. So I thinking really giving those bolts a good tightening may fix this problem.
