That would be jtag wiring my friend which I don't see the point if it's on that dash...This xbox will not update to any dash. It is stuck on 13604. Don't know if that has to do with this mod that I recently discovered(see picture) after opening it up due to e74 error. Thank you very much.
The E74 error means the eDRAM on the GPU is faulty and it is almost impossible to replace it (it's also not worth the hassle to even attempt it).Hmm... ok I wonder if that's preventing the update. I'm gonna remove all that sh*t and hopefully it will update once I bake it.
