My Samsung Galaxy Note 5 SM-N9208 just FRP locked and won't let me do anything, it's because I forgot to turn on the developer mode after I turn it off accidentally. Please help ASAP. sorry for my bad english.
Thanks before.
You have to, depending on the phone, put in your unlock password or PIN, then your Google account login and password. That's what FRP is - the phone is locked until you put in your Google account login and password. You can't just unlock anyone's phone by doing a factory reset.
