CPD1 modem on 5.1.1... Need help to go back to 5.1.1 modem

So I got the MM OTA notification the other day and popped on here to see the status, low and behold there is a bootloader unlock and root methods out. Well I once I got the free time I backed up my stuff and started to do the bootloader unlock steps. Well not thinking I did the factory reset from in android. That then (I think) started the update process instead of just factory reset. I pulled the battery real fast and opened up odin and installed the full firmware tar for 5.1.1 but I notice that I now have the cpd1 Baseband version which is MM 6.0.1 modem. Correct? How do I revert back to 5.1.1 modem so my wifi works and I can continue the rooting phase? I tried to just install the 5.1.1 modem through odin and it said success but it didn't change.
