Note 5 on TotalWireless won't update past PD4?

I bought a refurbished Galaxy Note 5 and have used it on TotalWireless for a few days before I noticed the Note 5 should be on BPF4. When I received the phone it was already on BPD4, my wife's phone upgraded from a 5.1.1 firmware and went through the full chain to BPF4 previously. Will an ODIN flash back to a 5.1.1 firmware allow my phone to pass where it is stuck currently?

Thanks
