iPhone 5 won't restore - error 2001
Hi,
As the title says, I've been having a little trouble with my iPhone 5, running the latest iOS. A few days ago it started to be tricky to come out of the locked screen (with the screen staying black unless I tapped the lock button, then the home button again). Then, it switched of altogether. On connecting to a mains power source using the original apple lead, it went into the loop of the apple appearing, then disappearing. On connecting to iTunes via my mac, it was not recognised. I forced it into DFU mode (which only happens when connected to the power source - is this normal?) upon which it was recognised, albeit offering only a full restore. On selecting this option and ensuring I have the latest version of iTunes, it goes through the motions of retrieving software, preparing to restore iPhone, then brings up the error 2001 message. I have used different ports, restarted my mac and used a different cable, all to no avail and still with the same message coming up.
I think I've covered it all! Does anyone have any suggestions on what else I may try? The phone has been mine since new (at launch roughly) and is not jailbroken etc nor has it ever been.
Thanks in anticipation!
