@twigg37531 "this secondary error code is caused by the GPU reset communication. If this test is not completed successfully on boot up, you will get this 0020 error code on the Xbox 360 console. This can be caused by TONS of components as there are multiple areas that manage this info, and could be bad." Check for more about that [link|https://www.tinker-mods.com/xbox-360-red-ring-of-death-guide/three-rings/0020-xbox-360-secondary-error-code.php|on here] as well as [link|https://www.youtube.com/watch?v=-c0z11KRI7w|on here] Most common issue will be the GPU. A reflow might fix this. Going to be a tricky one but for $20 you got nothing to lose. Go ahead, give it a try and let us know how it worked out.
