I just got an iPhone 5 from my friend. It worked well and I decided to restore it to reset it. Yet it is now restarting itself every 3 minutes so I'm trying to do a factory restore. While letting it connected to my computer I pushed the top and menu button and went to iTunes. I get this message ~without any interaction~:
iTunes is downloading the software for this phone and will restore
~It seems to be stuck, but it eventually restarted but~ it keeps restarting itself every 3 minutes.
Between restarts I can start to set the IPhone or even to use it a bit as everybody does if I was fast enough to set it.
I think I achieved to reinstall the OS, but it keeps restarting itself every 3 minutes.
