Just got my Active back from Samsung Warranty Repair for a non working back button. I was AWS and SIM unlocked so I could work on T-Mobile. They removed my AWS unlock and flashed it to 4.3.
I am unable to downgrade it to MF1 to AWS unlock it I get Secure Check Fail in ODIN (Never did before, same computer, same files). All known other methods to AWS unlock end up in error in QPST.
What do I do?? The only firmware that now flashes to the phone is 4.3 ML2, nothing else will flash to it without secure fail. Without AWS unlock the phone is a paperweight.
I just use the unlock code. No need to enable any aws bands. It works out of the box for me on ML2. Using tmobile. 4g lte

Nope, it's not AWS unlocked. TMobile works on some bands that ATT uses depending on your area. Unless you hack the modem, it's not AWS unlocked and you won't get LTE in all areas.
Is anyone on the OTA 4.4.2 and still can use AWS on Tmo? I'm still on MF3 and hesitant on changing because I did the AWS Modem Unlock in order to get LTE to work on Tmo and don't want to lose that. Insight would be greatly appreciated!!

I don't know if it works on 4.4.2, but there is a version that works on 4.3 so try asking in that thread.

agree with you
me too want unlock LTE
Download any MTK Engineer Mode app from Play, under Bandmode select any band you want. However after reboot, you lose these bands so you have to manually turn them on again

The only band available via Engineer mode is 12, the remaining are disabled in the radio. This has been documented in several posts.

I'm not familiar with the MTK Engineer Mode app, but doesn't it just execute AT commands? If so, all we might need is the AT command to enable band 12 and add that to an autostart script (assuming the phone is rooted).
Do you have this one? http://forum.xda-developers.com/showthread.php?p=69158594
