[Q] GS4 for Cricket SIM unlock for international use
I have a galaxy S 4 for Cricket model SCH-R970C. I need to unlock the phone to able to use the SIM slot outside the U.S. I've been able to root the phone and I tried flashing a i9505 ROM thinking that would unlock the use of the SIM with no luck. The baseband modem firmware does not change when I flash a different ROM. There is little to no info out there about the cricket GS4. Is it possible to flash different modem firmware so that the phone can behave as an i9505 model? The hardware is the same... just can't change the modem firmware.
I need this ASAP otherwise I need to find a new phone! I'm not in the US now and calling Cricket is not an option. I tried flashing a different modem firmware using ODIN but it fails. What am I missing?
Any help would be appreciated. I'm willing to "donate" $$ for a solution. Thanks.
