[HELP!] ROOT Fail on latest firmware update. Software Version G900PVPU3BOF6

PLEASE HELP!!!
Problem: Unable to ROOT device from the moderator ~~~~~ SOLVED
Solution: ???
Backstory
I was rooted on the previous stock build (G900PVPU1BOA6). Then thought it would be a good idea to update firmware before flashing the Mother of All Roms (MOAR) . Little did I know that it was only for G900PVPU1BOA6. Since I couldn't update directly through phone I updated through Samsung Kies. ( Removing ROOT and Twrp). Then I wanted to start fresh. ( Everything back to default factory settings). Then I tried rooting again (CF auto ROOT) and installing a custom recovery (Twrp) but then Odin v3.07 failed a quarter of the way through. (Failed authentication).
If anyone has a solution please feel free to message me​[/FONT]

I have SM-N910C with triped knox. I flash poland android MM with odin. After reboot i have error - device does not have DRK please install drk first and android cant load.
Then i flash twrp 3.0 with odin and all is ok, no errors and android load and work.
How can i repair that error? I want to use stock android 6.0 with stock recovery.
I Just wonder weather you have installed CM13 on you mobile before, and faced some problems before reverting back to touchewiz - If that is the case, then I would think they are many people will face this same problem whenever attemting to upgrade to Marshmallow !!

Extract tar file with 7zip then delete sboot.bin and cm.bin and re compress all remaining files in .tar with same 7 zip and flash with this method you can even go back to marshmallow or any firmware.
I did it. But when I'm flashing by your method Baseband shows unknown and both IMEI gone (invisible)...

install 4 files will start installation which will be interrupted after the first reboot because the phone will start in recovery now restart the phone and quickly press three buttons to enter the download mode then install the file:
CF-PBH6-Auto-Root-hero2lte-hero2ltexx-smg935f
the phone will stop at the samsung logo do not worry about it just wait after about 2 minutes there will be restart and after the reboot the normal installation will start. works 100%
I'm sorry for my english..
I have the same problem, manage to solve it?

Galaxy A3 2016 (sm-a310f) downgrade fail with twrp.

I want to downgrade my phone from android 7.0 to 6.01. The performance of the new OS is so bad that the phone is almost unusable!
Odin will not let me downgrade because the bootloader/modem etc is an older version.
I installed TWRP with the instructions from this thread https://forum.xda-developers.com/samsung-a-series/general/twrp-3-0-0-galaxy-a3-2016-sm-a310-t3316176
However when I try to install the 6.0.1 rom I downloaded from sammobile I get an "no md5 file found" error from twrp.
I thought that twrp is so versatile that it allows any rom to be installed.
Any ideas? Am I doing something wrong?
If you downloaded a ROM from sammobile or samfirmware they can only be flashed via Odin.
