Hey guys, since 2 weeks my phone is searching for service, and it seems it isnt a software problem. Delete the iphone, and doing a recovery gave me a signal in the first try. But i was unable to get any service when i tried it a second time. I did not drop the phone, that problem just occured out of nowhere. Switching Airplane Mode on/off does nothing at all. Do you guys have any ideas where this problem come from? Im still waiting for my tools, so i cannot say if a connection is loose or broke. I think the problem is the dock-connector - i got some problems syncing my phone too. Thanks for your opinion
It could be a dock connector. There’s an antennae located there. If you’ve tried everything software you can think of and you’re having problems syncing. Honestly if you haven’t taken it apart, you may want to be wary of this. Error 53 is on the rise, and if you consistently update to a new iOS. It may be better for you just to take it into Apple Update (10/27/2015) Ok. You can try this iPhone 6 Top Left Antenna iPhone 6 Teardown
Every since the release of iOS 9 Ive been seeing tons of phones with intermittent carrier signals. I would try updating or restoring the phone first.
