S7 Edge T Mobile Downgrading to MArshmallow

[Android Central Question]

Hi, I am having trouble downgrading my s7 edge to marshmallow 6.0.1 on mac. I have jodin3 installed and when it trys to look for a pit file it restarts the phone and disconnects my connection with jodin3 and does not allow me to restart the process. Does any body know the pit file for the s7 edge on t mobile. I am new to this and can use any help please.
