I tried to change my modem to an earlier version hoping that I could try to unlock carrier from 4.4.2 but instead I just stopped my phone from working showing no baseband or other important numbers and no service. With this modem download you provided I was able to sideload and run my phone fully working again. I searched for hours for a solution like this and yours was the only one I found.
Thank you thank you thank you
Still wish I could unlock my phone but maybe I'll try something another time. Using a Canadian samsung s3 with rogers.
