Chosen Solution
After changing logic board and Touch ID into another rear housing and display, the wifi icon is grey in control center and settings toggle is grey. Bluetooth can be toggled through control center but doesn’t enable in settings it just keeps spinning. I put it back in the original housing and problem still persists. Help is much appreciated.
The internal traces were damaged when the nut was torn off, dead.
@promaster123 check the back and top of your faulty logic board. The grey chip there is the Wi-Fi chip. Coming out of it are lines for the Wi-Fi signal going to the antenna. Is anything missing, broken off, damaged on that line? Otherwise you could have flexed and/or damaged the Wi-Fi chip itself. You can post high-res picture of the board in that area if you’d like a second opinion. EDIT: looking at those pictures, it seems you have long screw damage to one of the screw holes which can typically cause this loss of Wi-Fi.
What’s this at the bottom of this picture? Isn’t the screw nut missing?
Before you inspect any physical damage:
- check you date and time! If date is back in 1970 ( usually is) set it right to current date.
- try to change region ( just something else than the a proper one), try wifi… and after that set it up back in the proper region
- set date/time on Auto try wifi if it is not working - set it back to manual
if this is not working, try hard reset (Home button and Power button together till you see Apple logo and then release bot at the same time)
So I dont know if youve solved it yet or not, but in the first picture it appears that the wifi antenna was not connected to the back of the board before installation. The wifi is the squiggly wire in pic #1, not the one that runs down the side of the board
