Bought a samsung 6 edge plus off Craigslist. Of course it's in retail mode! I already tried the 5444 password, but no luck. It's asking for the store password. I have no idea where it came from. I tried "rollback" for Wal-Mart muy that didn't work...i tried "blue" for best buy...that didn't work. Any other thoughts? I don't really know how to root. Is there more passwords I should try? Ugh what a ripoff
