My iPhone 5 could not connect to my carrier. My iPad did however when I put the iPhone SIM into it. The iPhone did not warn about "No SIMM"
That is why I decided to restore the iPhone. Now I get Error 12 most times when I try to restore the firmware. Sometimes it is Error 3.
My MacBook Pro with OS X Yosemite 10.10.2 (14C1510) and iTunes 12.1.0.50 was able to update my iPad to IOS 8.2 after the first iPhone restore failed. So I suspect that there is no problem with my computer reaching the Apple update servers. I gave up trying to restore using my Windows 8.1 PC after it responded with Error 3014. I know that that computer has Firewall issues.
Unfortunately, after the failed restore, my iPhone will not even give me access to email, iMessage or FaceTime.
This iPhone is in perfect condition but it is out of warranty. Apple would charge me £25 before providing any online support and the nearest Apple Store is over 100 miles away. Would it be worth getting it repaired or should I just scrap it and buy a replacement phone.
