Noob question really stuck

This is my first time unlocking a phone I have sony ericsson K850I and its locked to Rogers network. I flashed the firmware using 1. K850_R1FA035_MAIN-GENERIC_SO_RED52 AND K850_R1FA035_FS_AMERICA_RED52 ALSO US K850I_1201-0095_R11A_GENERIC_AMERICA. After several attempts it changed the firmware but shows it still locked I am confused. Any help would be appreciated. Thanks

I don't believe a2uploader is capable of unlocking phones, You should look into setool or using a pay service I believe.
I am a bit of a noob as well, but this is my understanding.

you should use omnius to unlock your phone..a2uploader can't do it..
