Must the phone be S-OFF for this to work? I remember on a Sprint HTC One thread someone got it working with an odex ROM on S-ON, and I've done it as well and it worked. Can the same work with the Sprint Max with an odex ROM and S-ON? I'm still S-ON but bootloader unlocked, yet it's not working for me. The SIM Unlock Helper app just sits there without opening the place to tap simlock.
