You can't downgrade bootloader, so you can only flash U6 or higher. So unfortunately you won't be able to downgrade

Because from 4xxxx firmware bootloader is locked so you can't downgrade further

Should I root my phone based on baseband version or build number ?

Hello ,
I have a galaxy S7 G930F
I used to run android 7.0 and rooted with CF ROOT, after a stupid mistake OF OEM UNLOCK I got the RFP lock & i didnt know how to fix it without loosing data , So I flashed it but to Android 8.0 OREO , and I did an update from Samsung official to the latest version of security patch
Nevertheless, I want to root my phone ! but I'm confused as I mentioned in the title which file I should download from firmware.mobi ?
PHONE : GALAXY S7 G930F
SAMSUNG EXPERIENCE : 9.0
BASEBAND VERSION : G930FXXU3ERKF
BUILD NUMBER: R16NW.G930FXXU3ERL3
in software update this is what is written :

SO which file I should use from firmware.mobi to root my G930F ?
Thank you and sorry for long post!

[HELP] Samsung S8 won't downgrade security patch level from January 1, 2019

I just downgraded my Samsung Galaxy S8 from its latest android patch, Android 9 (pie) to an older version that was released on September 2018. But I notice that the security patch level of my android won't downgrade from January 1, 2019. Is there any solutions.
Additional info:
I downgraded my device using Odin
why would you want to downgrade the security patch level? :/

Samsung J8 touch screen unresponsive/not working after Oreo 8.0.0/8.1.0 to 9.0 Pie.

I don't know if this is related, off-topic or not. But my brother had this problem after he updated to 9.0 pie update on a samsung j8 phone.
Here is my build number and baseband.
Baseband: J810YDXU2BSD2. Build Number: J810YDXU2BSD3
Country: Philippines, XTC.
I would like to know what firmware should I download to downgrade using flash odin.
:crying:
Hi , I think it will not be easy to downgrade from Android 9 to 8 but you can try with this one :
