Wifi button greyed out, bluetooth has spinning icon.
All,
I have an iPhone 6 that was suffering from very poor to nearly unusable wifi as well as bluetooth unreliability. I pulled the motherboard to check if the flex antenna was good. When removing the flex antenna 3 of the connections came out fine then the third fell off without me touching it. The connection had not been properly soldered to the board.
I tried to solder it back on, but it was beyond my soldering skill (some solder wicked up into the connector and ruined it). As a result I purchased a new main board. After install of the new mainboard I reset and began a restore from cloud on the phone. Wifi connected without issue, I did not get an opportunity to verify bluetooth. After about 20 minutes of restoring from iCloud a message popped up saying the wifi connection was lost and the restore could not finish. After this the phone was back into the same state (wifi greyed out, bluetooth unable to connect). I tried multiple factory resets etc. with no success and tried pulling the motherboard and inspecting my work, I found nothing wrong.
With all work I was doing I used a magnetic screw organizer and labeled every screw. I’m confident I used the correct screws in the correct places.
What I’m doing moving forwards: While I was careful not to touch any connections and the board came with the flex antenna already attached, I did NOT know the cover on the top left was part of the antenna and it is possible I touched it. I’ve ordered a new cover, flex cable, and screwset. I’m going to replace all of that. I will also be cleaning the connections in that area with denatured alcohol and a cotton swab to remove any oils. After that I’m unsure of what else could have gone wrong, I’m wondering if I got a bad board. It seems very odd that the phone would work fine only to stop.
Can anyone offer advice on what else I should look at?
Thank you!
