First off do not heatgun your 360 board.

Depending on what you're actually looking at it may be normal. If you can REALLY see the BGA joints then you're not fixing that for sure. What you're probably seeing is something that looks like this...




...which is perfectly normal, this is the CPU but the GPU is the same way. If it looks different than this and you can see much more under the chip then you're not gonna fix that at all, since it's most likely ripped up traces and pads to get any higher off the board and you couldn't manage that by just removing the heatsink unless you used a hammer or pried on it with a pretty big screwdriver.

Isn't his problem exactly what the "heat gun trick" is for? You can try an X-Clamp replacement and heat gun trick all in one. Or if you can successfully heat the chip and reconnect the broken solder points, you can try putting epoxy on the sides of the chip to hold it in place, provided you test it extensively and it works for you. The epoxy *might* work, at least for a while, apparently MS had tried doing this before.

No, the "heat gun trick" is for people that have no clue what they're doing and like taking the chance they may ruin a board that may still have some life in it. If you want them reflowed properly then take it somewhere that has that capability.

If the thing is off the board that far you have 1 of 2 issues, possibly both.

1. The pads and or traces have been lifted with the BGA joint and that's not easily or cheaply fixed at all and sure as crap isn't going to be "magically" repaired by a heat gun.

2. The actual chip is most likely seriously bent in places it never should have been and could be damaged as well.


You can try the X-clamp replacement on it, but I wouldn't hold my breath on it ever booting again. What did you do to get it in that shape anyway? Just removing the heatsink (correctly) will not cause that kind of damage.

[brandogg]

It could have simply been caused by the board flexing due to the excess heat - then it cooled down and un-flexed, but since some of the solder points were broken, it made the chip bend slightly. I'm not recommending that he uses the heat gun, and I've never done it myself, but I've read many many posts on this forum where people fixed their problem by doing so. You can also try simply doing the X-Clamp replacement, as has been suggested, and I'd suggest trying to find some of the pads that they used to put on AMD processors, which could possibly even the tension on the chip itself. If you do it, try with a variety of washers and amounts of tightness for the screws. Using one nylon washer under the heat sink, with a nylon and a metal washer under the board, fixed my error 0020 system, although my GPU was not noticeably raised off of the board, but it was 100% a GPU problem on my system.

If it's off the board as far as he's stating then he can heat gun it until the end of time, it's still not going to repair a lifted/broken trace or pad.

well i got this from someone who wanted me to fix it as i have done many successful x-clamps replacements.  i did the x-clamp at first and of course was a no go.  so when i looked closer at the gpu you can tell its not the way it should be.  they had messed around on the inside before i got it so not sure if they broke it or if it just got that hot where they broke away.  i compared it to another box i have and it is definately messed up, lol.  so i guess im gonna have to give him the bad news.

Ace, can you describe the shim that you made that fixed the 0020?  Wsa it something you put between the heatsink and GPU that forced the heatsink to provide pressure to the GPU edges when screwed on tight with the X-clamp mod?  I have an 0020 problem too, and I can physically see that my GPU is slightly warped upwards on one edge.

RBJtech mentions shims on his site/thread, it's basically a 0.5mm or 1mm thick piece of aluminum or copper taken off an old heatsink. I found that 2cm x 1cm that RBJtech states is too small though and it was more like 2.5cm x 1.5cm iirc.

Here's a picture http://rbjtech.bulld...../xbox 002.jpg

hey man Iam interested in this shim you speak of.
 I went to the link that you put up on here but the link was dead.!

I also have a xbox 360 with the 0020 & im not sure what to do to it thats why i was interested in this shim.

[sidhu123]

Also interested in this "shim". Been getting a 0020 error from a few days back, and nothing seems to have worked so far. Tried the X-Clamp fix as well as the penny trick just for kicks...but neither seem to do anything.  

[mxrider56]

I am also having this error 0200.

If anyone has found a way to fix it, or any ideas, would be much appreciated

Well, I´ve fixed a few Xbox, and tried different methods, x-clamp replacement being the most easy, harmless and effective. A couple of days ago my cousin´s launch console finally rroded, code 0020, after years of good service, unbelieveable it has worked for so long under heavy use. Anyway, no method seemed to revive it, until I remebered someone telling to heatgun the bottom only, so I did it and it´s alive again. Haven´t tested much but it seems to be working fine, enough to justify some cooling mods to see if we can squeeze some more gaming out of it.
The board was perfectly straight, I was expecting some warping but no, at least to the naked eye. Hope this helps someone.
I´m also using credit card pieces under the Gpu/ Cpu heatsink to even the pressure against the chip.

Isolated the issue to the back chip by pressing on it and booting, so I took a dime and put a piece of electrical tape over one side, then put it tape side down between the sink and chip and replaced the modified clamp. works great now. hopefully this will help other people fix the 0020 via what I now call the dime fix  

[MadMaxGR]

Could u post some pics of your fix?

[drewis]

The 'back chip' you refer to is NOT the ANA, its the 2 ram chips covered by the GPU heatsink right? If it is, ive tried that too, no dice.
