Iphone 5c

Hi guys, Ive got my mates iphone 5c, which has been damaged to a point where I cant get a screen to work on it. He tried to fix it himself, but I think hes fooked the plugs on the mobo. Ive even bought a full assembled screen and that dont work.

I need to wipe this phone of all its data, but itunes wont let me because "find my iphone" is turned on. I know the pass code, but cant enter it with no screen.

Is there a way of connecting the phone to my pc and doing it vis the pc?

Cheers.

Go to www.icloud.com, sign in with his AppleID, Find my iPhone, make sure he is looking at the right phone and do a remote wipe :)

Of course, didn't think of that! Cheers.

Try itune on desktop it will backup all the things.
