I know theres people who unlock these for GSM for cheap but I would like to learn how to do It my self cause I buy a lot of sprint locked galaxys with owed bills for dirty 2 bought 2 s7s today for 120 for the pair. So I was looking to unlock these and I will flash them with U1 which that part is ez lol. the running android 7.0 on these and Im pretty sure its simple to do if u know what your doing. the guy who dose it for me it only takes him like 10 mins max and it just flashes something with odin and its good to go. I see where people say u have to root the phone which I could probly do I just don't know what u would do after that to make it GSM unlocked.
