I had big problems at the weekend after running the new ios7.0.4 upgrade. My whole phone went black. A friend took my phone and eventually managed to get it back up again for me but now my itunes account cannot find my iphone and my Facebook application has corrupted (or it looks like it). What do I need to do? Thanks
iPhone 4S, iOS 7.0.4
If you can get the phone to backup cleanly, or have a backup from the upgrade, you should probably go for a DFU update -

Pop the phone into DFU mode and get iTunes to reflash it from scratch.
I've worked in mobile software for 14 years, and it's my opinion that updating mobile devices over the air with partial updates is a bad idea. I always update and migrate iPhones using iTunes and a cable. It's the best way to be safe, from the start.
When your iPhone tells you to update, do it with iTunes. Pure and simple. If you're not near your PC or mac, wait until you are.
I have tried this and I have again lost my phone. It remains black and the drivers install again then it goes to preparing phone for restore - the apple logo appears with the bar and then itunes just says waiting for iphone for ages and then it comes up with the iphone logo and connector sign. It then says
"iphone could not be restored an unknown error occured 4013"
And now nothing on my iphone again!
Please help!!!
Also ive noticed that no serial number is coming up in itunes it is just saying serial number n/a which Im sure it has never said before!!!!
There's another couple of answers on that iTunes error -

Otherwise take a look through some more via google -

The consensus on fixing seems to revolve around the PC running iTunes rather than the iPhone in what I see here. You may need to uninstall iTunes and reinstall it, or try using someone else's iTunes to do the software restore.
Good luck and check the solutions in the links above.
