I have to sync an iPhone 4 bought used at a particular iTunes (v10.1) offered me an updated firmware (from memory, to go from to v4.1.0) followed by restoration. Since then, attempts to restore continuously, even in DFU mode, even uninstalling and reinstalling iTunes, even attempting the restoration on another PC, the sequence is as follows:
the device is detected by iTunes, which shows:
iTunes has detected an iPhone in recovery mode. You must restore it to use it with iTunes -> OK.
-> Restore button
-> Restore button and update.
Checking catering preparing iPhone for restore, The iPhone "iPhone" could not be restored. An unknown error occurred. IPhone 4 and Apple Component Cables do not work. Please help.
