A friend gave me a Galaxy S5. She turned on some sort of 2 step verification through Samsung & FORGOT ALL THE VERIFICATION INFO. It was on contract through Verizon so she paid it out of contract & bought a Note 5 & just created a new Samsung account so the S5 is no longer under a contract. She gave me all info she could remember & her sales receipt & even went with me to Verizon to see if they could help - they said the solution would have to come from Samsung but she called them & was not able to get them to unlock it because she couldn't remember any of the verification info. Someone told me if I got the phone flashed, that'd unlock it. Can anyone tell me if this is true & if so, how to go about flashing it?
