Hot-Air Gun specs:

 BOSCH PHG 600-2 CE

 2000 Watt

 50-600C

 air flow 300/500 l/min

I think I have a solution to fix error 0102.

My x360 has the 3 blinking lights (error 0102). The Xbox360 was booting up and suddenly it froze, sometimes at X-logo or in dashboard. Sometimes I had also picture errors. (Vertical stripes and many rectangles) like this:

[1] [2] [3] [4]

After 20-40 reboots I got it to work! But why?? You know that the metal expands itself a little bit if it is warmed up.

Then I opened my xbox, turned it on and touched the BGA memory chips. During this the xbox got more pixel errors and if I pressed strong enough, all pixel errors disappeared. :?

I thought that I have found the problem, but when I pressed on the Southbridge the same thing happened again. Sometimes more picture mistakes sometimes less. So this means, that the problem is something there. Maybe cold solder joint??

I remembered, that I still have a Ti4600 GPU with defective BGA RAMs. It makes funny signs and symbols if I touch it.
So I used my Hot-air gun [5] and heated up this BGA chips. Then I waited till the graphic card have a normal temperature. And you will not believe it! All runs OK, no changes when I touch the RAMs. I also played with it and tested it with benchmark, no problem any more. :)

And now I have done the same work with my xbox360. [6] And also here, everything works in the best way no freeze, no pixelerrors or horrible noise and no bootup problems.

I think MS has saved on high-quality tin-solder. If you look at your mainboard you will find some bad soldering points and sometimes soldering splashes. :/

Attention I cannot guarantee that it will also works on your xbox360! If you still want trying this, be carefully and do not move or touch anything when you heat them up.

You must warm up everything steadily. then you must also heat up the Southbridge, GPU and BGA RAM (in circle movements) very important: Do not hold on it all the time and do not touch nothing also the Mainboard.

I can not tell you how long you must heat them up, I do it more with feeling, but not longer then 2min! After that you must wait till the system is cool down, about 20min.

I set the gun to max temp to heat them up. and for gradual lowering used approx. 300C and then 100C
