edit:
I just realized the 2 times which I heatgunned, I never heatgunned the bottom of the motherboard, only the top for like 4 minutes, could that be why its RROD so quickly?

Heatgunning the bottom reduces the risk that it comes back, always do the bottom first and then the top , the top is more important..
Concentrate on the GPU->(H)ANA chip area as 0022 is a bridged solder joint under the GPU(like 0020) + a fucked up ANA chip connection(like E74 aka 1022)
Make sure you do it for 4 minutes then you can be sure it reflowed properly...
I have fixed a couple of these already and the only way to get rid of it permanently is heatgunning it properly.

One of my mates got it a while ago and I had to fix it 3 times, the last time I fixed it with a heatgun and applied the X Clamp(before just X Clamp replacement + overheating etc) replacement and it has been working well for 5 months now...

So when gunning the bottom you want the mobo  to stay right side up but heat from underneath (so the chips dont fall out?) I'm on break from work (drove home, about 2 minutes). Before I left a few hours ago I heated the top for a few minutes, just did it again right now. When I get home tonight in like 3 hours I'll attempt to do the bottom then the top again.

Well you just turn it around so that the bottom is the top(sounds a bit weird but I am about to go to bed so...)
make sure it is in a good position and doesnt have any space to move.
The chips wont fall off because they wont get hot enough, the main function of heatgunning the bottom is to reflow the bottom RAM and the capacitors and resistors under the main chips...
Heatgunning the top actually reflows the GPU top RAM etc..
Doing the bottom first is smarter just by thinking of it since you soften the solder of the GPU and CPU but dont reflow it and since gravity is pulling them down they might become slightly looser.
If you first reflow the bottom and then the top you wont have this problem...
It will most likely not be a big deal but it sounds logical and in the low percentage of the cases in which this might be the problem you will be on the safe side if you do it this way

[Squeakk]

well I did wait a few hours before heat gunning the bottom (about 3 - 4 hours)

Mine just alternates between 0021 and 0020 and sometimes just boots up and plays fine for hours.  I'n going to do the x-clamp today but my hopes are not high.

Sounds like some cracked solder joints under the GPU which are shorting out...
0020 is a short under GPU/RAM/CPU traces which lead to the GPU
And 0021 is also a short but Southbridge related, can be a bridged joint under the GPU that leads to the Sotuhbridge or a bridged joint under the Southbridge itself,...
It can also be a problem with the power of the components like a loose capacitor, missing capacitor etc so check for that as well.
Try to heatgun the CPU->GPU->RAM->Southbridge area if the X Clamp replacement doesnt help...

[fallte]

I will. It's very hard to determine the exact spot though. And I do seem to have a damaged trace on the underside of the board that I have probably scratched while trying to remove the clamps. However id did give me an error even before I had opened the box so that seem unlikely. The problem is that lazy as I am I gave it to a repair shop that claimed they would fix it and which later turned out just heatgun it without even removing the clamps. I hope they haven't burned anything.

Ye there are a lot of retards like that on Ebay...
Could you take a picture of the broken trace?
0020 can be caused by a cut trace, so you might have to repair it...
Are you sure that the error you got before was 0020?

[fallte]

No. 9 out of 10 times it would throw out 0021 and just occasionally 0020. I figured it was a broken solder joint that sometimes wouldn't contact at all and sometimes would short out and that's the reason for the different error codes. Anyway I really need to do the x-clamp thing first - I couldn't get the parts today since I live in the back end of nowhere. So maybe tomorrow I'll see if it gets fixed that way. I'll take the picture of the trace but it's so small I really don't think my camera is good enough to display that. And you can only see it if the light is the right way. Even if it turns out to be damaged I really don't have the skills or the tools to repair it.

0020 and 0021 are both bridged solder joints/ power issues, only the location of the issues differs(GPU/CPU/RAM and GPU/Southbridge)
0021 might also be overriding 0020 or vice-versa so you cant know for sure
where exactly is the scratch?

[DarkSabre_X]

is a heat gun w/ lower temps or more adjustable better than a dual temp one w/ only 750f and 1000f? found one at a local ace hardware and for 35 bucks it gives temps frm 250f to 1350 f.  i know the question sounds silly cause more variable temps prob gives me more to play w/ but if i can save the $10 that is the diff i be so happy. (although even 35 is better than 279 for another 360)

I got a heatgun with 2 steps
1st step 250°C(482°F) and 2nd step 500°C(932°C)
You cant really preheat with this one is the problem thats already like a 400°C.
What you would have to do is use a hairdryer or something but the easiest solution would be to spend 10 bucks on the other...
You Americans get the 360s quite cheap though, I pay 279€ for a new one... Thats a 446.40$

[DarkSabre_X]

well the 279 is for the arcade considering i already have a hdd. but ok i'm going to get the multi temp one.  i'll post the results once i get the heat gun. thanks

[fallte]

I did the x-clamp and it worked. And that trace really looked cut. Go figure. Only time will tell.

[moreniu]

Error 0020, was 0110 before replacing the x clamp... Did not put much pressure at all but it just won't change out of 0020.

Removed the heatsincs, cleaned the thermal paste, did try heatgun it for a while all over the hana chip > gpu > cpu > ram, 1 min @300 c~ then around 2-3min at around, and still gives me error 0020... What did i break?? ><

Thanks!
