Flashing to Stock FW after mobo replacement - Samsung Galaxy S7 Questions and Answers

Hi guys! I just need some help just to be sure I won't brick my mobo again. Samsung service center replaced the mobo.
I have the SM-G930F. Booloader: G930FXXU1DQJ8 CSC: G930F0JV1DQIL
I just have a few questions which you might be able to answer.
Basically what I want to achieve is get the firmware with least bloat and faster OTA updates.
Currently, my CSC is in KSA and the updates here are really slow.
Questions:
1. I am currently in Qatar, is it safe to flash a different country firmware? If yes, which country should I get base on what I want to achieve? (least bloats and faster OTA)
2. If I flash a new firmware, will I be still able to receive new updates over the air? I have not rooted this device since I got a new mobo.
3. What options should I select to retain all my data when flashing a new firmware? Home or just CSC?
4. What files should I flash? Just the AP?
5. Can I just flash any CSC I want? For example I want the BTU CSC.
Thanks in advance!

Flashing G930F "BTU" (UK) Nougat firmware in the USA - CSC change needed?

Since there is no official Nougat release in the USA yet, I was planning on installing the "BTU" Nougat official firmware intended for the UK. Do I need to do anything with changing the CSC to use in the USA, or just flash everything as-is in the firmware download? I don't understand if the CSC change is REQUIRED to match the country you are using the phone in, or just recommended. The current Marshmallow build is showing a CSC of OJV (middle east)
What are you USA folks out there doing? I am on Straight Talk (AT&T sim).
My current phone is giving me a lot of problems, and I'd really appreciate a response as I need to get switched over to this S7 ASAP. I realize I can just use Marshmallow but am really hoping to get to Nougat so I don't have to reflash and potentially lose data down the road.
Thank you!
If the CSC you want to change to is not included in the CSC already on your phone, you'll need to use CSC of the new ROM (Not HOME_CSC) along with the other 3 sections, and check the "Repartition" option in PIT settings of ODIN
This will wipe your phone back to factory settings
Are you rooted?

He doesn't need to check repartition. Despite the fact that it is designed for downgrading and unbricking (exclusively, in most cases ), it is not required to do that if only CSC change is needed. Only thing he need to do is using CSC section of the ROM (not Home_CSC because it is preserving old settings in the phone, message to The Founder of the topic ).
Generally, when I was switching to BTU I flashed Firmware with CSC different that BTU (for example Sweden rom) and then flashed BTU sofware. CSC has changed flawlessly
And when you have rooted phone, you can change CSC manually. That extremely ease you effort.
i would just flash the firmware and the csc that comes with it because then you will get updates in the future. if the csc doesn't match the firmware you wont ever get updates so just do a samsung cloud backup and flash the nougat But its weird that someone in the usa doesn'ty have nougat because i thought usa was 1 of the first with nougat.
RiTCHiE007 is right. If you want to receive OTA updates, CSC must match with the type of firmware it comes from. That is why you need to change CSC from US to BTU. Here is a thread that will help you out providing explanation of the topic.

J7 Prime Firmware Flashing

Hi guys! I tried posting to a different forums but no luck in replies. So, I tried to go here and find some answers.
So, Im waiting for the official update for my phone (SM-G610Y - here's my latest firmware: PDA - G610YZTU1AQF2, CSC - G610YOLC1AQF1), but Im planning to flash a new firmware. Although, since PH-OpenLine havent rolled-out a firmware nougat update, I want to use Australia's firmware (PDA - G610YZTU1BRC3, CSC - G610YXSA1BRC3).
Questions:
-Will my phone still work if I will do it? And will my device status change from official to custom?
-Should I use all four files (BL, AP, CP, CSC) when flashing the update/firmware?
-Will there be any conflicts/problems?
-If it caused a problem, can factory reset (as others said in other forums) work to revert back to the original and official status of the phone? Or will there be any solutions to rollback?
Thank you!!!
Hi
Install this software .... Phone INFO ★Samsung★
The CSC tab (page 2) will show you the compatible CSC codes for your device. I.e. installing official software from those countries should be ok.
Flashing official software won't change your status, aka trip knox
Flashing your original, official software should restore to factory state.
Good luck!
Thank you for replying and answering some of my questions.
So I decided to use Australia's firmware. I just wanna ask which one is the compatible csc? Is it the available csc from the phone info app? If yes, XSA is not included, what will be the problems when I continue to flash it (if there are any)?
And more importantly, should I flash all 4 files or just AP? And any important matters before I flash?
Thank you!
If XSA is not on the CSC list, you need to take care that the mobile networks in Australia are compatible with those in your home country - both gsm?
Also I would avoid a network specific firmware.
Any specific reason for choosing XSA?
Flash all 4 files.

How about I update using XSA and changing my CSC code after the update is finished? Will it work?
Whats a network specific firmware? Is it the one uploaded in the sammobile (thats where my firmware came from)?
And no, I dont have any specific reason for choosing XSA. I only have 3 options (NZC, VFJ, and XSA).
Sorry for being a newbie and thank you so much

If your home network and Australia use the same radio tech i.e. gsm, no need to change the CSC, just upate

E.g. for Israel (ILO) is generic for rest of Israel. There's also firmware specific for Pelephone in Israel (PCL)[/I]
And no, I dont have any specific reason for choosing XSA. I only have 3 options (NZC, VFJ, and XSA).
I see why now .... Here is a faster source .... you can use a download accelerator 610Y firmware on Updato.com
Download and enjoy!

More on the network specific firmware - for Phillipines XTC would be generic (Open Line). XLA Smart and GLB Globe would be network specific.
Okay, I'll try it later. Thank you so much!

Note 20 ultra d/S firmware

I don't find note 20 ultra Dual sim firmware. Does the N986b/ds use same firmware as the N986b without loosing dual sim function? Reason I'm thinking on flashing is cause I have a xfa version and network reception is really bad and thinking on flashing btu. Do u guys think that a new firmware might help? (all other devices I get 3 bar at home and with note 20 ultra sometimes I have no network)
Check here for your required FW.
N986B is the Global Exynos model (it is Dual-SIM = DS); in case if any regions are single-SIM for this particular model (I'm not aware as such), the N986B FW will still be the same as for DS.

It's possible I think.
But..... only try other Exynos region FW (cannot flash FW for SnapDragon variants on N986B without running into problems).
Check on Note 20 threads regarding properly changing CSC.
Also, there are some .xml modification solutions that enable you to activate extra 4g/5g bands - worth a search & try.
(Sorry I don't have the links to hand, but recall seeing these discussions before on N20 XDA forums).
I'm with Three UK does this help

When you un-compress the firmware download you will get five files. Each go into a specific part of ODIN - can't mistake it - but if you want to keep data intact you will need to flash Home_CSC. This will NOT change your regional CSC however.
You also need the "hacked" version of ODIN found on this forum easily.

If I flash that 5 files will I still be able to get Ota?
When I flash should I use CSC or HOME CSC. So that I keep getting updates? I think that if I flash UK international firmware, will sort alot of my issues. It feels in my country software is never very stable.
Flashing CSC will delete your Data but flashing HOME_CSC will not delete your Data.

Will both ways I still get Ota even if I install btu firmware? (is there any benefit on me flashing the csc and not Home_CSC?)
Once bootloader unlocked I don't think you can get OTA - You'll need to flash FW updates manually.
Flash CSC for clean install.
Flash HOME_CSC if just updating FW & need to preserve user data.

So if I flash a different rom I won't be able to do Ota anymore?
No

Not unless you re-lock BL.
Hopefully they'll come with a solution. I would like to flash a different rom (different country) and still get Ota updates as normal. I don't wanna be flashing every month
These are stock roms, why do you need to unlock your bootloader?

I end up selling my note 20 ultra. Signal was bad. I'm using my p30 pro for now until I get something else. But I doubt will be a Samsung.
Thanks for help guys

Question XSG csc

Hi guys i bought a galaxy s22 ultra (S908E/DS) and i saw it now the the csc is for Arab country. i live in Bosnia (Europe) is there any way to change the csc to eux? thansk for infos
I guess you bought device is snapdragon and you needs a CSC which available on;y on exynos. If there is no issue with network then better keep as it is.
Alternatively try flashing HOME_CSC file from stock firmware of EUX, most likely it may get block by odin. In this case only way is to root device and force install EUX CSC, again I don't recommend it if their is no valid reason to change.

yes its a snapdragon model. i have no problems with network yet shoudl i try over odin to flash the whole firmware or just the home csc file? is there any chance to brick the phone because its a snapdragon variant? i ask because of OTA updates?

If you are looking for OTA, you never get Exynos OTA on Snapdragon.
You can not flash full firmware, I'd suggest to flash standalone CSC file in case you have network issue. If you have everything working related to network, I strogly suggest to NOT to mess up. Still you will get OTA when you have new update for arab country.
why i cant flash the full firmware? is it because its a snapdragon or something else? can i mess up my phone when trying to flash the csc via odin and download mode?

Question Change region from Korea to Global (or Nordic) on S21+

Hello people, I hope you're okay!
I bought an used S21+ but it was not clear that the model I would receive is Korean (G996N). While I don't have any issues, it also misses the eSIM option (and probably Samsung Pay is not going to work in Europe). The eSIM option would be really good to have (SPay I do not care a lot).
I've been searching for an answer in regards to change the region and the responses are mixed and I am out of Samsung phones and firmware loop for a few years. Some say I can just change the CSC region using SamFW and that's good to go. Some say it will not work because my KOO CSC does not allow this change. Also, OTA firmwares are lost until I switch the CSC back (but, from what I understood, if I also change the firmware it would receive OTA normally).
Question: is it possible, nowadays, to just change Firmware and CSC to another region? My phone has an Exynos processor so it would have to be a firmware from Europe or Latin America.
I also understood it will not brick nor trip knox efuse, right?
Thanks a lot!
@angourakis Ok let me give you a clear response about CSCs. ALL Samsung firmware will let you flash a new CSC (as long as you use Odin). This has worked for me every single time.
You need to update your Android to the latest 13 and download and extract this (remember to use “direct download”, this website is the only one with a good selection of firmware) and use Odin (get 3.14.1 non patched) to flash the HOMECSC file (in the CSC slot).
Hey @traman124 thanks for the response!
Why this firmware in specific? I am running a more recent firmware than the one you mentioned. Also, do I need to have the bootloader unlocked?
Thanks!
It doesn’t need to be that version @angourakis it can be any version… that one will work though And you can use Odin with a locked bootloader (with download mode).
@traman124 thanks again!
Unfortunately, I tripped knox while trying to install a CSC from G996B version (kept BL, AP and CP from G996N and only used CSC from B version).
Now I am trying to look for a trade in program to replace the phone.
Thanks anyway, I really appreciate your help!
@angourakis I’m sorry….. this has never happened to me while flashing CSCs but the few times I have I did it with the same variant phone/tablet…..
