Since I was able to circumvent this problem on my iPad by using a different computer, I switched from my MacBook Pro to our iMac upstairs and voíla, it worked. I have no idea what’s going on, but my MacBook Pro appears to be the culprit… Hmmmm. Not sure what to make of that.
2. iPhone can’t boot normally.
It turn on and turn of again.
I’m not sure is it’s hardware problem?
Then wait about 10 minutes to update, and of coarse you should’ve backed up your data, then VOLLA! Your iPhone has been fixed and updated. If the fixing your iPhone method didn’t work, I’m sorry, but your iPhone is totaled. You will need a new one, or you could go back to a Nokia (NOT) XD . If the update didn’t work, take my advice, and do NOT, I repeat, DO NOT go to Verision, AT&T, or whatever you use. The most they would probably just give you a new iPhone. Go to the nearest Apple Store and explain that no matter what, your iPhone just can’t update. They will attempt to update it, and if THEY could not update it, it is just about certainly a system error, so get a new iPhone. I hope this helped you, and PEACE!
