Hi guys,
Im wondering if anybody could help. Ive got an iphone 4 and im trying to do a full factory reset but it wont let me as i cant turn find my iphone off as i dont know the password? I have to trade the phone in with samsung and it has to be fully wiped as part of the conditions. Im wondering is theyre a way around this? like software or something? thanks

Just sign in to your Apple ID on a browser and enter your Apple user. (Email address) and try and reset password.

If you can not unlock it from the iCloud (find my iPhone) then the phone is useless and can only be sold for spares!

There’s no way around it save for changing the memory board!
