I've got a got water damaged iPhone and the screen no longer allows me to see anything at all. It turns on fine and I think in some parts the touch sensors work as well. I could use Siri yesterday but now I try to use Siri, it keeps saying unavailable and connect to the internet.
I need to turn off Find My iPhone so I can restore it to its factory settings but when I go into iCloud from another device it says its offline. I've tried checking to see if calls can come in but no luck and I've tried swiping up and tapping where airplane mode would be but still no use.
Any ideas on what I can do to so I can get my phone back online again so I can at least use it to call and attempt to disable Find My iPhone? It can be seen by iTunes if that's any help?
iPhone 5, iOS 7.1.2
