Dear Friends,
I am owner of 910U device on L , rooted and with TWRP.
To update MM, I was going to flash Offical firmware of MM 6.0.1 , to have latest modem bootloader.
But we do not have root or CF auto root, for MM yet. So I cannot root and re flash TWRP (as I think)
However, I have seen some people on forum that have MM on 910U device, with root.
So I was wondering, Is it possible to keep root and twrp while flashing orginal firmware?

As far as I know, there is not root method for marshmallow yet. I flashed the original firmware which reverted root.
I'm on MM, but 910H model. I took a chance and flashed 5.1.1 cf auto root from chainfire, for the 910H and it worked. Just rooted, no custom rom. No problem whatsoever. Smooth as butter.
Thank you all. I did. thanks to @djmax
1- I Flashed, modem and sboot of 6.0.1, over L firmware. System was working.
2- I flashed erobot firmware of 6.0.1
3- flashed SUSE MAX kernel of djmax work for 910U
4- rebooted, : had no signal, no superuser, noise crash for calls..
5-Flashed modem, sboot again for 910U
6-flashed super sU zip 2.71 from chainfire
7- flashed noise fix for 910 U
8- flashed SMSfix from erobot..
ALL working now.

Kindly guide me someone i want to downgrade to marshmallow on SM G935A .. i have tried the apk1 rom but failed to flash please help...
You'll get used to Oreo, it's pretty good so far.
Assuming it's still on bootloader 4, you can downgrade to any firmware build using BL4. I don't recall off the top of my head if there was ever a MM build that used BL4, but that's the restriction. Anything else will either not flash or brick your device. You will need a modded version of ODIN to do the downgrade.
why do you want to downgrade?
I want to downgrade firmware from 337 to 334. Can't do video calling in 337. Please help.
Ps: no twrp and locked bootloader.
Not possible without twrp...wait for next update..it might fix the reason you are downgrading for
I have a G930V running G930VVRU4BRC2. Is it possible to update to the latest firmware, G930VVRUACSF2, via Odin without updating the bootloader too? If not, do i have to stick with the latest in the v4 bootloader, G930VVRS4CRI1? Is there a reason I should not update my bootloader too? Like the ability to downgrade?
Thanks.
Trust me you don't want to update and to awnser your question I'm not sure but I am sure that the firmware itself has the bootloader number so by flashing from RS4 witch is bootloader 4 to RUA witch is bootloader 10 it would be impossible to downgrade just upgrade to a bootloader 7 and lower you should be fine
