How to downgrade from MM to LP? - T-Mobile Samsung Galaxy S6

Hello!
I want to downgrade from stock 6.0.1 MM ROM to stock 5.1.1 LP ROM.
I have G920T with G920TUVU5EPK5 stock rooted ROM. Also I flashed 3.0.2.1 TWRP recovery.
I little bit don't understand how to proceed following these instructions:: https://forum.xda-developers.com/showpost.php?p=66460264&postcount=2137
What should I do next?
1. Download a correct 5.1.1 custom ROM, for example OZOP v14 for LP, yeah? https://forum.xda-developers.com/tm.../rom-ozop-v1-fly-theming-mod-options-t3162489
2. Flash the bootloader, but when I try to flash DOJC in Odin I see error:

Please help!

you won't be able to downgrade anymore because of bootloader binary 5, you can only flash firmwares with bootloader 5, so stop before brick your phone. Lollipop has as far as I know bootloader binary 3.

Check to see if you get FRP lock message on your screen when you flash, also before flash any other rom go to developer settings, then turn on OEM unlock first.
If you don't know how to unlock developer options in setting then please do a search on xda and you will find it for sure. Hope it helps.

Still have stock recovery after flashing twrp on eqe2 firmware (latest)

Coming out of an old build of Maximum Overdrive from last year, I felt the need to update. Wiped, found base/build epj2, flashed and rooted that. I guess that wasnt the latest build, it think it was released in oct 2016. Had major issues with this firmware, So i rewiped, reflashed epj2, and just let tmobile ota's take over. Now Im on baseband/ build N910T3UVS3EQE2, which is the latest firmware to date.
My problem, flashing twrp does nothing. Im getting no errors in odin, (see text below) when I reboot into recovery after flashing, I still have stock recovery. First time Ive encountered this. If its relevant, Ive tried odin 3.12.3 and 3.12.7, and twrp 3.0.2 and 3.1.1. Im out of ideas at this point, and my searches have turned up nothing related to specifically root issues related to eqe2 firmware.
Any tips would be appreciated Thanks!

TWRP Recovery might be Released within a few months for this base, now if you can downgrade to epj2 then do it and redo the twrp if you cant then try to downgrade to 5.1.1 and then upgrade to epj2
I'm on the same build but I'm able to install TWRP and it works. I can even install different versions of TWRP. The problem I have after is no matter what ROM I try to flash after I get either error 7, error 6, or errors about the zip file. When I try to Odin it just crashes. I wonder if this build is more secure than others?

Here's the problem. It's impossible to downgrade to firmware with lower bootloader version. However, it is possible if you unlock your bootloader, flash custom recovery and then flash your Oreo through TWRP/OrangeFox.
