Root Proximity sensor issues

I have two different Zmax phones, both running the newest BrokenOS (2/03) and one of them, which originally was a b30 is working totally fine on Broken after flashing the b22 modem.....the other zmax was originally a b33 and no matter what sensors I flash (flamingo or redbull) or modems (b06 or b22) it just refuses to make calls properly. Screen goes black, soft buttons light up dimly, and I cannot be heard on the other end. I am stuck like this until the person I called hangs up.

What am I missing/doing wrong? Any ideas or help or ANYTHING would be super appreciated.
