Hello, I purchased 30 credits to unlock my LG K500um and i selected both K500um and K500um (spr) on the tool and after failing twice the 3rd time it finally unlocked it but I was not able to change my APN settings when using my AT&t sim card. I activated the phone on boost (on my girlfriends account) to see if this reset something so I could add an APN (to use with my AT&t service) but it now relocked the phone back to boost so now it says "invalid" sim when i put my AT&t card in.
What is proper solution for complete unlock so I can change my APN after? Im out 30 creidts and still locked device...
