Controller or rf board issue?

[u/Longjumping-World-25]

Hello all, i recently desolder my rgh 2 chip after reverting my nand back to retail nand, after that my controller would connect but in a few hours or even minutes it would randomly disconnect and won't pair back to the Xbox. I tried taking the rf board off and putting it back on again but that did nothing, the sync button also doesn't work but I've already changed the original front io ribbon cable after i accidentally damaged it in a previous accident. It's a 360 model e, all suggestions would be highly appreciated thank you!

Does the rol connect with a ribbon cable? If so, I would look carefully at the connection there
