Well I am done now.
I added an alternative method for those of you who dont want to use tape to fasten it.
I recommend the easier tape method though because it doesnt isolate the chip at all, the heat is only transfered to the heatsink anyway and the thermal probes in my own 360 pretty much confirm that.

The missing diagram for metal/ spring washers in between mainboard and screw was added as well

And I also added a warning for using too thick tape.

Next update will be for the hybrid of RBJTechs and mine that M2X is testing out but this will still take a while I guess...

USE AS5? WTF? Why not a little glue or something? AS5? No offense, that is the dumbest thign I have ever heard.

[jimbobjim]

Yeah you can buy really strong adhesive/epoxy that can withstand temps of over 200C... that should be just about good enough for a 360

Now that is the dumbest thing ive ever heard... ^

You dont use glue because once it gets hot it melts...

First of all, Chill out!  
Well if you had read this thread you would have figured out that certain people who complained about the tape dont want to remove glue residue in case they have to take it apart ever again, this is why!  
AS5 can also easily be removed and a side effect is that it is easier to apply a thin layer of AS5 than glue....

Same here...
You can basically use whatever you want if you dont care about the residue as long as it is not too thick...

You are thinking a bit extreme mate, this would only happen if there was no washer in between GPU and mainboard.
And you would also have to tighten the screws extremely snug and the mainboard would crack before it bends like that.
I am not denying that there is a slight flexing under the chip, you can never eliminate that completely but because of the even larger surface area the pressure is shared up to the whole chip so less pressure is necessary and it will flex less than every other fix that you can find here.

I have also seen your fix on the pictures, it was actually a nice idea but you forgot that the mainboard was flexing when you put the GPU in plaster.
This is a significant mistake that will lead to even worse flexing because once you take everything under pressure the bottom parts will act similar like an x-clamp(bottom part looks like a hill and the top part like the negative of a hill) and push the center under the chip up.
At the same time the top part on the GPU will be pushed down and take the outer solder balls under pressure.
Since the whole thing is still flexing though and the plaster only keeps it in its old position(in the best case) this wont work reliably...

My fix doesnt have this problem because the creditcard has got the exact height of the GPU die and so the chip is perfectly flat.

To get your fix to work properly you would have to put plaster on a working non flexing mainboard and put this on a broken one in order to fix it by pushing it back in its perfect position without any flexing...

The X-Clamp replacement will fix it if it is GPU related, to make sure it isnt the (H)ANA chip I would recommend that you reflow the solder under GPU, (H)ANA and in between.
First do the bottom, 1 min preheat 4 mins on high -> wait 45 minutes , then isolate the top , preheat for 1 min heatgun for 4 min-> wait another 45 minutes.
Afterwards do the X-Clamp replacement.
Should fix this one forever...

Thanks! Much appreciated!  
I'll do that and post the result for sure just after I find a good and worthy heatgun. Still I'm looking for it.
Hope I could help you the way you are helping us...

First of all I must say $hit 10 times!  
Why?
Cause I'm so screwed...
DAMN MAN!
Here's the story:

As I promised to Wilhelm I was going to test a hybrid of RBJTech's and Wilhelm's method today.
All went good until the part that I wanted to place the card pieces with a thermal paste.
I had just got some phone cars the other day and I cut the 2x2mm pieces soooo easily.
Then I placed them in their places and I applied a thin layer of thermal compound on the die and then I replaced the heatsink with 3 washers. I tightened the screws and then removed them again so I could see if there's good contact with the heatsink or not. I saw that there was no sign of thermal paste on the heatsink. So it was making zero contact with the die.
I then used 2 washers, no go. 1 washers still nothing. No washers and then I just realized that the hight of the card pieces were not good. They are exactly 0.8mm high. So I said WTF? I pressed them tightly with some tools and then redid everything. Still no go.  
I had no idea what to do. I had nothing else to replace with the card pieces and the damn owner needed his box real quick.
So I actually missed the chance to do the hybrid method and I just used RBJTech's method and then ....

Some good/bad things happened with me getting a little screwed...
With some hopes I might have found a possible cause/fix for 0002.
I connected the power supply and turned the thing on.
Right then it showed me the beyond beautiful 0002.
This was the box that had some random 0002.
I loosened the screws on the CPU side a bit and turned it on again...
Then the 0002 error was gone but some 2RRoD just popped after 3RRoD.
I was just like this:        
Then I realized something was happening and it was something that should never be.
I noticed that something like dust was flying in the air... But wait!! DUST??! NO $HIT! It was white smoke coming out from somewhere around the CPU heatsink along with a horrible smell of electronics circuits.
             
I immediately turned the box off and removed the power cable and etc.
Then I quickly removed the heatsinks (and I realized that the bolt in the upper right corner of the CPU was boiling hot!
Then I examined the other side of the board.
As Wilhelm already told me, I knew that 0002 was a short somewhere near CPU.
I couldn't find the place at first but then I carefully smelled the board I and finally found the spot with some horrible smell  
It is shown in the picture below (as number 1) and as you can see there are some sign of short/bridged connection in there:



Now since I couldn't find the place that they are connected to (since the PCB is a 7 layer PCB if I'm not wrong) I became suspicious about the legs of those capacitors (shown as number 2) as they were longer than normal (comparing with other boxes that I previously fixed).
So then I thought I could use some electrical tape to isolate the spot and other capacitors legs as shown in the picture below:



After the isolation, I redid the fix (x-clamp replacement) and tampered with the nuts on the GPU side and finally I saw some green lights.  

So I think the 0002 is caused by the bridged connection in the points in the pictures above.
IE if they are bridged the system will never power on and goes straight to 0002.
BUT if they get somehow bridged then the system won't probably realize and this could cause a major catastrophe perhaps.
But I might be wrong with all these. Me and other people should do some more research on this matter.
If isolating the points in the pictures could actually solve 0002 then it would be a possible fix.
Any ideas?

PS:Thanks for reading the long full of crap story!!!  

Now one other thing. There is another 0102 box here waiting to be repaired. The thing is I have something like 3 days and the owner is not in a hurry in no way. Perhaps if I get lucky I could test the hybrid method on this one.
Now the problem is I can't find the right thing to put on the chip.
What should I do? Any suggestions?  
I really really would like to do this hybrid method and see the results.
Any help would be appreciated in advance...

Quoting didnt work somehow so I just copied it...

1) Well try to use the thin tape I used the next time, I havent tested the thermal compound method, it was this jasonel dude who told me it worked for him...
Also make sure it got the same height as the die, just hold the card beside it it should be exactly as high as the die.
I dont know what a caliper is and I dont think I have got one I would know otherwise so I could only measure it by comparing it with a metal washer.
I bet on the thermal compound though...

2) Well this confirms pretty much what I thought.
What I found out about this one so far is that it can be caused by a lifted up CPU, so a cold or bridged solder joint.
And it can also be power related, probably when the CPU isnt getting clean power because a cap is missing or bridged like you showed here.
The fact that 0102 is a cold solder joint under the GPU give me more reason to believe that 0002 is a cold and not a bridged solder joint though

The very last thing that makes me sure that it is rather a cold than a bridged is though what I experienced with the tampered 360 I got from Ebay.
This 360 used to have 0102 I fixed it by heatgunning.
Afterwards I figured out the RAMs were flat and the error code changed to 0020(some retard obviously tried to fix it with a heatgun   )...
However I used this one for tests instead of selling it on Ebay for parts.
What I did was cutting the temperature traces of the CPU because some guy was having weird overheating problems.
After that the system didnt show the 2 red lights for CPU overheating anymore.
Like you might guess the thing became literally burning hot.
I noticed though that the thing did a click after approximately 30 seconds which I found weird.
After having some fun cooking my CPU a few more time and hearing this click noise I decided to check the error code after this clicking noise.
Right after this click the error code always changed from 0020 to 0002.
Because of the high temperature some of the solder joints probably lost contact and became cold.
After turning it off and back on the error code was 0020 again...

As I said before already I also got someone to reball his CPU to fix this error and I hope he will be able to solve this little quest definitely...

It is like 99% sure that this error is a CPU related cold solder joint or if what M2X said is true it can also be a problem with the way the CPU is powered.
Since the CPU usually throws the error code(if I remember right, correct me if I am wrong) it might just be an error code that is caused when the CPU doesnt know whats wrong like with 0001 it is not powered then, so might be the same with 0002...

3) Have you got MSN maybe?
If so add me communication is much easier then...
As recommended before already try the tape method...
The fact that it overheated might also be somehow related to the cold solder joint under the CPU probably it shortened the temp sensor or so...
