0002 Xbox 360 secondary error code | Three red rings guide
Let's talk about what's wrong
Getting a 0002 secondary error code on your Xbox 360 console means you have an issue with power. If the console can get power to critical parts but still have areas that aren't functioning, the 0002 error code can appear. This could be a simple problem or a major pain. So let's talk about each area of concern.
Did you try to repair it?
If you tried a repair on your Xbox 360 console using a reflow machine there is a good chance your blower pushed parts off the motherboard while attempting the repair. Usually this would be the outer rail area of the CPU or GPU chips but could also be on the motherboard itself. You may need a picture of a second mobo for reference to locate missing parts. If none of this is the case you may have bought the console from someone who caused the damage. You could have a much more serious issue with parts such as mosfets on the main board. If you are skilled enough that is next step.
A faulty power supply
This could be a simple problem. A bad power supply/brick could also be the cause. The 0002 secondary error code can be caused by a power supply that isn't functioning. Try replacing it and see if this is your issue. If the RROD and 0002 code goes away, then the power supply needs to be fixed or thrown out. There is also a chance you are using the incorrect power brick for your Xbox 360. Luckily you can check out this guide on which power supply your Xbox 360 needs to see if that's your problem.
