running latest bootloader/modem question

Hi guys
searched the forums but cannot find the answer.
I have a 935f and its running the latest bootloader and modem from november. i just got this phone and have rooted and installed TWRP, when i am looking at custom roms like superman and renovate, it tells me to "update" my bootloader and modem to octobers version for superman or septembers version for renovate.
obviously i a running a later version than both of these, am i ok to flash the rom without doing anything or do i need to downgrade my bootloader then flash?
if i downgrade will i have to root and install TERP again plase?
thanks in advance for the help

Q about updating firmware on unlocked bootloader and rooted phone

Hey guys, I recently bought an Zenfone 3 but with the first ever firmware. I was also successful in unlocking the bootloader and rooting it. Now, nougat is released and i cant receive ota. since i wanna update to nougat, do i have to flash the updates in order or is it okay to skip to the latest firmware then update to nougat? and also how do i flash it? do i need to wipe and stuff like that? I've already uninstalled xposed btw. Thank you for any help

Install stock recovery back, then flash stock nougat zip.
no wipes needed.
you can download the ota from asus support site.

Planning to buy G935W8, had a few questions

Looking to buy this phone soon but I was just wondering about a few things. Im buying the canadian variant G935W8.
1. Can this device be rooted on nougat as well or only marshmallow? Im buying it brand new so I think it will probably be running the latest firmware.
2. Is there any issues with unlocking the bootloader? Is it neccesary to do so if you want root and custom roms?
the bootloader is not locked on the w8 as its the exynos variant and yes nougat can be rooted its the same as 935f

Thanks. Also another question I had. If the phone comes with marshmallow and I root it will I be able to install nougat roms directly or will I have to update the bootloader and modem? In that case would it be better to update it to nougat first and then root?
Updating your phone would cause you to lose root anyways as the file structure on nougat is completely different then marshmellow.
Rooting also prevents OTA updates, so you would end up having to install nougat manually.
I suggest you upgrade your software then root it. You can use systemless root from magisk. Using TWRP just flash the latest magisk file and you are rooted. The file will automatically root your phone as part of the installation process.

If you get it with MM (highly unlikely) just don't do anything and you should get an OTA notification otherwise you can download Odin, google it as I don't have a link and nougat from here https://www.androidfilehost.com/?fid=457095661767144483 and you can flash it yourself now rooting is a little different then it used to be do a search on the s7 edge for the info on that
the reason is yes you will need to download the BL not sure about modem but you might as well do it too
I just rooted my G935W8 running 7.0 by following the instructions in the first half of this video.

Possible to root on latest firmware?

Hi guys, I'm wondering if its possible to root if I'm on the latest stock firmware?
Unlocking the bootloader is already giving me headaches with Huawei not giving codes out anymore.
Thanks

update firmware but not bootloader?

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
