SM-G9910 S21 Snapdragon - Samsung Galaxy S21 Questions

It's it possible for me to flash my csc for a different country? It's currently BRI and i need to change it to enable 5g and other functions which seems to be broken, like caller id. I have a Snapdragon version and the csc i need is for a country released in exynos.

Additional question, is it possible to flash SM-G991B firmware into SM-G9910?
If not how can i just change the CSC?

I know nothing :confused:

Hi there, I bought A5 2017 from Qatar and now using it in India and gulf models does not support voLTE feature so I need damn voLTE and some suggest me to flash to Indian firmware because Indian model have voLTE and when I search on sammobile there are plenty number of Indian firmware with different PDA, CSC and also does not know about PDA and CSC. SO can you please tell me which firmware is best for my device. I am totally confused.
Device Name - Samsung Galaxy A5 2017
Model Number - SM-A520F
UAE - TRA ID: 0016333/08
TA: 00000000/00
Baseband version - A520FXXU1AQEA
Build number - MMB29K.A520FXXU1AQF3
Please tell me doing this safe or not, what consequences will be, by doing this does give me voLTE, after flashing to Indian firmware do I get future software.
THANK YOU IN ADVANCE
I don't think different networks bands can be added through software, or maybe I am wrong.

Change CSC

Hi,
I have a Samsung S9+ Unlocked (MXO) Is possible to change the CSC code in order to get updated quickly? It is still on September update.
Check at https://www.sammobile.com/firmwares/galaxy-s9-plus/SM-G9650/MXO/ here you can select the CSC you want and check which CSC got more recent update, but it seems mostly all are on same page/patch...
But changing CSC may result in some extra problems mainly warranty, VOLTE and SPay and all..
Since your seems not snapdragon you may have more options in hand..
But think before changing CSC as if you opted samsung they u have already taken decision to bare slow stream of updates.... and oreo is not yet near so why in hurry...

Flash mxo unbranded, but if your carrier is Telcel you'l lose volte. And I think there isn't way to get back
MXO is the unbranded CSC on México, Im guessing flash some CSC from USA. Will it be OK?

Download either BTU or DBT firmware and you'll be fine.

Flash a different Region

I know the question has been here before, but i dont seem to find a answer on my specific question:
I'm the Owner of a Galaxy S9+ - It's a "NEE" region
I want to flash the German (DBT) region firmware. Will this mess up the phones KNOX? It's official firmware from Sammy
Flashing a different region firmware, will this mess up the "modem" regarding the bands and etc.? I live in Denmark
I wish you all to have a great day out there
You can flash dbt version with no problem! Knox will not be affected and your csc will be nee !!!

TGY and ILO regions frimware compatibility?

Basically, I've bought Galaxy Tab S7 in Israel, but when I booted it up, I've discovered that it uses TGY region firmware. I'd like to know if I'm allowed to change firmware to ILO region and will there be any consequences for doing so?
And is there any usable material to read of what firmware from what regions is compatible to firmware of other regions?
Thanks!
