I would like to restore factory settings on my iPhone 5. When I try to do this via iTunes, the computer tells me that I have to change the iCloud settings on my phone: deactivate "Find my iPhone".
Unfortunately both buttons are inactive on my phone, so I am not able to get to the settings menu. I am also not able to reboot it. I have tried pressing both of them for a long time to no avail.
Do you have any ideas how to get around this?
