Hi, I have a Galaxy S5 that was given to me by a friend. She locked it through Samsung, couldn't remember the password or information to reset the password. Instead of going through a ton of trouble to get it reset, she went to Verizon, paid it out of contract and bought a new Note 5 and opened up a new Samsung account. She gave me the S5. Can anyone tell me how I can get it unlocked by Samsung? Would flashing it work? (Note: she also went with me to Verizon to see if the sales rep there could help get it unlocked - no success). Any input would be greatly appreciated!!
