Don't change the packages or you will brick your phone. This packages are not a full flashes, only modems.
This is under your own risk, I'm not responsable if you brick your phone.
This solution is not mine. I just funded.
This is only for downgrade from B13 to B6 and B33 to B22. Not for oder version. Please be carefull
I hope this can help you.
