No service, tried replacing cellular antenna but no luck.
This is a very frustrating and akward story! I purchased a faulty iPhone 6, which gets No service or keeps "searching" all the time. I noticed that unplugging the battery, syncing the time and date, and restoring the network settings, works partially (because after turning off, or just turning on airplane mode stucks the phone again in the previous No service problem).
Another thing that I noticed is that removing the pentalobes screws and the two battery holder screws gives me again signal for like two days and then I need to restart the same procedure of "restore".
I tried replacing the entire dock aswell and it seemed to have fixed the problem (and did work with all screws bolted too) but again after two days it drops the signal again and I'm stuck like this.
Any help/ideas? (Phone is factory unlocked and imei is clean aswell.)
Is this a good question?
