Hello guys ,
   I had an iphone 5c but i have upgraded to iphone 5s . Recently i had to use the 5c but it had a password (4 digit) and i couldnt remeber so i factory reset'd it . When i was using the 5c my friend asked me to connect on his apple id and game center to buy him some gems on clash royale cuz he didnt had a cc . Now when i try to setup the 5c it tells me "Activation Lock This iPhone is linked to an Apple ID. Enter the Apple ID and password that were used to set up this iPhone b*****@gmail.com" and when i tried to log in it told me that the apple id got blocked and i have to reset the password, but my friend told me that this email isnt his email but the password that he usually has is his password . I dont know what to do if you have something that you didnt understand please ask them here

I suggest you just go to an Apple store for them to sort it out.
