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.

Thank you. Do u think if I flash a different country firmware, might help with poor signal?

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

If I download BTU firmware and just flash it with Odin won't it just install firmware and radio software? Sorry I been away from Samsung for some years now. In past was just easy to flash a d all would work.

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.

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

Hey guys,
Been a while since i've done any flashing of ROMs and memory has gone to mush entirely on the subject so have a couple of questions... I'm looking to flash the UK 7.0 BTU rom on my New Zealand carrier branded handset because carriers here suck and take For Ever to push updates.
Basically I'm wanting to know if i'll have any issues like my csc getting messed with, or knox tripping and voiding my warranty and upsetting apps, and do I need to worry about the Modem?
Thanks
I did it the day it came out and no issues. I flashed the BTU rom with the standard CSC and everything works fine. I did not flash the HOME_CSC.
Knox not tripped and working fine for me.

Hi
Well , if you use CSC you will factory reset you phone and you will set it to the default csc in the flashed rom..... you could use the home_csc from the latest available stock rom from your carrier in your country ( or whichever cscs your phone has) that way you will not factory reset your phone...BUT as you are using a home_csc from a 6.0.1 into a 7.01 rom there may be some issues ...some carrier specific options may be lost..

That answered some of my questions, thanks.
Please see screenshot for my mutiCSC firmware. I am running Android 7 but haven't changed CSC since I got the phone in December 2016. I got it with Marshmallow on it. Everytime I upgrade firmware with Odin I select Home CSC so my CSC never changes.
Since the solution is in the CSC (afaik), which CSC do you recommend I flash with Odin? I understand how to flash with Odin if CSC not in my multiCSC firmware (tick re-partition, etc...)
My home network is Vodafone (CSC is XVF which is not part of my CSC).

If i got it right you are not root, right? if you are root there are other ways....
Yes you need the right CSC to make it work , in this case Vodafone XFV.
When you change to a different CSC is recommended to check re partition to adjust to the possible change in partitions
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930F/XFV/download/G930FXXU1DQD2/131635/
Download the firmware and extract the correct CSC from it , if you do not want all the vodafone stuff you could download and unbranded firmware and use the BL ,CP , AP from it and the CSC (XFV) from Vodafone and flash it all together
BACK UP FIRST .......

Let us know how it goes
Hello,
I have a Samsung Galaxy S7 SM-G930V and I cannot receive and send MMS.
I am in France
I made several adjustments in the apn, but in vain.
So I want to flash the phone to see if it solves MMS problems.
Problem, I can't find the right files for the file.
I installed this one
https://www.sammobile.com/samsung/galaxy-s7/firmware/SM-G930V/VZW/download/G930VVRSBCTC1/329889/
And that installed a VERIZON overlay and that wasn’t what I wanted at all and it didn’t solve my problems.
Can you tell me the right files without operator overlay?
thank you in advance
Hello
can you tell me that original firmware version to this phone?
thank you
Nobody knows ?
Your best bet would be flashing the G930U firmware, it's the generic non-carrier specific firmware intended for carrier unlocked phones. It would have the best chance working in Europe.

https://www.sammobile.com/samsung/galaxy-s7/firmware/SM-G930U/XAA/download/G930UUESACSF1/282459/
Make sure you flash all 4 files (AP, BL, CP, CSC), make sure you use CSC and not Home_CSC, this will wipe data but it will be necessary to fix your issues

It looks like you have an g930A (which is AT&T) as your PDA version, where it should be g930V or g930U. Make sure you download and flash all 4 files (BL, AP, CSC, CP). You can get the unbranded firmware from the same place you got the other at samobile. That is the G930U firmware.
Hello,
I come back to this subject late.

Apparently it's an SM-G930V

You cannot flash because the bootloader version is B11. Most threads don't mention the bootloader issue, either because the thread is old, or not enough people updated their firmware to experience the issue.

Is it the mismatch between CSC codes?
Firmware and active CSC codes are different.
Well, you have a phone from Malaysia; while the ROM is French.
You can change both.
To change ROM CSC that's simple. Grab the relevant CSC rom from Sammobile or any other firmware site and install via ODIN. (Most phones have a relevant section/guide in their XDA sub-forum.)
To change device CSC, you need tools and it may not be supported at all. I used "SamKey", you need to buy keys from the company, but it worked. On my Note 10+ it worked, on my Note 9 it worked, on my S10e it worked. On my Note 9 512GB it failed. Basically the tool has to support your specific device variant AND if you are on latest firmware you must wait because they need time to make the tool compatible.

With one CSC firmware i should flash?any suggestion??
Well, I suppose you want to match the device's CSC, so I'd grab the XME one from Sammobile. And you need ODIN to flash. The whole ordeal should not affect your e-fuse/warranty/KNOX status. At least I never managed to trip mine by doing these.
But, I also used mismatch CSC firmware for months if not years at times and it didn't do a thing. Like I didn't notice any difference. I wanted to enable call recording, but I realized it only works if I change device CSC and then also flash the relevant ROM.

SamKey is a paid, third-party software.
- You have to buy credits for it to work. So you need to pay.
- It may or may NOT support your device (they do refund if it's not supported).
- You don't need to be a Hollywood hacker to use it, but if you are really unfamiliar with everything in general - I would recommend not using it.

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?
