I have an iphone 5 locked on icloud ios 7 that one friend gave me (sold me for 200 bucks). He said that he gave me the iphone because it was locked and didn't know the icloud password. And i was wondering if i can restore it to lower version somehow. I already know the icloud bypass but it doesn't work because i don't really know what to do next to unlock it. After i bypass the icloud thing can i erase the account from the settings so it never asks me again? An as i mentioned earlier can i restore it to older version(s) like ios 5,6 in DFU or recovery mode?
