iPhone 5 suddenly developed the “Searching…” problem (no cell service, only wifi). After researching, I did a backup on iTunes, then restored all factory settings. Now, phone will not activate! Error message is “Could Not Activate iPhone because activation server is temporarily unavailable. Try connecting to iTunes or try again in a few minutes.” Have tried dozens of times through iTunes and wifi, even bought new SIM card, still SAME ERROR. Any ideas? Shows Wi-Fi is connected, and still Searching…Comm board maybe? Thanks in advance. This site is awesome!
The searching problem is pretty common on the iPhone 6, less so on the 5S. If you dial *#06#, do you see the IEMI number displayed? Not seeing the IEMI is usually a sign that the baseband IC is the issue. Sometimes a reball can be sufficient but it cannot be replaced. Has anything happened to your phone in the last few days/weeks before this problem occurred?
I think you must do a factory reset for you iphone ,try to press the button up and the middle button both in the same time and then wait until the factory reset is done..this could solve your problem!
