0020 will need a reflow or reballing. a heat gun will work to reflow it.
0022 is a cold solder joint on the CPU, not GPU. you can try doing the heating method on llamas guide for the GPU, but do it on the CPU. but it would be much much better to reflow it
0022 is damn sure NOT the CPU it is GPU related and is closely connected to the E74(1022)
I could fix it temporarily by doing the X-Clamps fix+ overheating. Later it returned sometimes as E74 or 0022.
After reflowing the area between the GPU and the ana-chip I got rid of the problem completely.
I tested it with a second xbox and used the heatgun straight away without doing the X-CLamp fix first and this fixed it immediately.
No disrespect but it is definitely NOT the CPU and I think it is time to edit the FAQ before more people waste their time and money on reflowing/reballing the CPU.
0020 can be fixed by reflowing.
However you should also check the surface of the GPU and CPU for any missing capacitors.
And it may also be caused by a broken solder joint of one of the big capacitors , here is a picture
