Hi All, A guy from work lent me his iphone to borrow for a few weeks whilst my phone is being repaired. I am guessing his phone was jailbroken but I went to settings and reset all data so I could use from scratch. This caused the phone to freeze on the black screen with the white apple logo. I have since tried all methods on the internet I can possibly find which just results in all different types of errors on itunes - which include 16OO, 16O1, 13O5 etc etc. I have tried the restore, DFU mode and everything Please could someone help? Should I just take the old phone into an apple shop and ask for help? I can't face telling my friend that I have broke his phone he kindly lent me. Thanks.
