Flashing another Region's firmware on Samsung J7 Pro (SM-J730GM)

Hello All,
Please I want to know the consequences of flashing the rom of another region on your Samsung device. Let me explain why I ask this
So recently I upgraded my Samsung j7 Pro (J730GM) to Android 8.1 Oreo and that update changed the binary version of my device to 5 (i.e. J730GMDXU5) so I tried downgrading the phone back to 7.0 but that did not work because Samsung has not released an Android 7.0 Nougat firmware with binary version 5 so downgrading the normal way was quite impossible.
Now I recently found out that Samsung has released an Android 7.0 Nougat firmware with binary version 5 but the region/country it was released for is Mexico while my phone's region is Thailand.
Now my question is, is it possible to downgrade my J7 Pro with the Mexico firmware although my device's region is Thailand because they are both binary version 5? If yes, what are the possible consequences?

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 :
version : G930FXXU3ERL3/G930FOXA3ERKF/G930FXXU3ERKF
SIZE; 470,74MB
security patch level : december 1, 2018
SO which file I should use from firmware.mobi to root my G930F ?
Thank you and sorry for long post!
one last question! how to unlock phone with home button ? I couldnt find it in android 8.0 and no setting --> display --> navigation bar does not exist in S7 !

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

[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? :/

Question Latest Software version

What is the latest software version for this device? I just got a Moto Edge+ 2022 XT2201-3 direct from Motorola and it only upgraded to February 2023, build S3SHS32.12-41-4-4... Is that the latest version?
I thought this device had Android 13 already...
