    Anyone can help me fix this issue?, I cannot restore or update my iphone 5 thru itunes.

    Known issues:
    - Cant turn on iphone, it only shows “connect to itunes” icon when usb cable is attached. (The possible restoring method would be on itunes only)
    - Cant restore or update iphone, after all the process of restoring and extracting iphone, a notification window pops up saying “an unknown error occured.(-1)”

    Anyone can give me some non technical possible solutions?(fixing without opening the iphone physically with the use of tools) Please help me fix and save my iphone, thanks in advance!

    *ps: I’ve searched the internet about the error code (-1), some says it is due to chip being corrupted.

    Some things to try.

    1. Use a computer that is capable of running the latest version of iTunes. Please note, I do not mean the latest version your computer can run, I mean the latest version released. If you don't have a computer capable of running the latest version you'll need to find one.

    2. Try different ports and different cables.

    3. May be worth trying DFU Mode. You'll know you are in DFU Mode if your screen is blank.

    Take the phone to Apple.

    It's most likely a hardware issue and nothing except repair or replacement can fix that.
