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.
