Free Flash Drivers

Hi guz,

I want to downgrade my NOTE 4 from 6.0.1 to 5.1.1. I googled it and did show one of the thread on this forum using ODIN method for that. My problem is to find the correct firmware version for note 4.

My device info is given below
Model Number: SM-N910F
Baseband version: N910FXXU1DPB1
Build Number: MMB29M.N910FXXU1DPE1

Please help me on finding the correct firmware or suggest me on identifying the possible versions.

Thank you.
