unlock bootloader,, Root your phone with magisk, download root explorer, navigate to efs/imei/mps_code.dat edit it with text editor, change from skc to KOO and reboot. Then relock bootloader, flash stock firmware koo. I had similar challenge, downloaded like 1000 firmwares, used all manner of softwares including paid samkey but could change till I tried above.

Not need to unlock bootloader and root. You can downgrade to Stock Android 10 and install Google Dial then enter code to change CSC to KOO

If he is on Android 12 bootloader not possible to downgrade bootloader.

Any idea guys?

Ikr, the phone isn't officially available in my country but honestly I don't want to brick my phone, I'll firt do a hard reset and see if there is any update, if not it means the update is probably on its way, maybe I'll try to flash a firmware later as a last solution.
Thank you anyway

You won't brick it if you are careful. No worries in flashing the firmware.
No Need To Flash Other Firmware..If Your Software is for vietnam then i would suggest you to stick with your own software...changing firmware wont fix your problem either you will face issues due to security policy on Android pie...wait for update

SM-N975F/DS Root, TWRP?

Hey, I unintentionally got the dual-SIM model of the Note 10+ (thought it seems that it's the only one available in my country right now). I know that you should avoid Dual-SIM models at all costs if you want to flash custom ROMs etc. But I'm not really interested in custom ROMs anymore. Just root and TWRP (for flashing stuff and backups).
So I was in the middle of doing all that when I realised I had the dual SIM model. It was mentioned NOWHERE, when I was buying the thing. So now I can't find the firmware for this thing anywhere, so I can't really root it. Is rooting this model currently possible? If not, can I restore a non rooted device backup on the device, after I root it? As root will eventually become possible for this device too? If it isn't already.
CSC is: N975FOXM1ASGO
Thanks in advance guys.
Whaaat? No. Yes Of course. You have the perfect version for root. I have the same dual sim version. Dual sim means root most of the time. You're good!

I have the international N975F, also with dual sim.
I have rooted it and TWRP is working, I used SamFirm to download the firmware.
When I put in my region code (DBT - Germany) it automatically chose the correct version. Mine is N975FXXU1ASHE/N975FOXM1ASHE.
You can try it with SamFirm with your CSC values.

I need the link to download required files for rooting SM-N975F/DS
Hi guys, I came here to give you a feedback on the root for that model (N975FOXM1ASG) because I have the exact same one, I'm French.
What @Brava27 and @JayanWarden is correct, I used SamFirm to download the latest firmware for that model using automatic,
with the model sm-n975f and region XEF.
Then I just followed this process:
https://forum.xda-developers.com/galaxy-note-10+/how-to/guide-how-to-root-note-10-t3960031
You have to follow it carefully
The only part that doesn't work for me though is "E.Flashing TWRP", but the phone is rooted.
This is now what I have instead of the default values likes yours:
[IMG ]https://ibb.co/ZK5pGpw[/IMG]
https://ibb.co/ZK5pGpw
Everything works 100%, so you can go ahead and root.
One thing though and it's not mentioned, but in the thread it says that if you don't see the option to unlock your bootloader you'll have to wait and maybe some will never have it...
This is wrong, in fact, you need to do the whole process without a sim card inserted, i know because I tried with and without and the option didn't appear when I had the sim card in the phone.

SM-G986B is Multi CSC device. Since Switzerland and Italy are in the same region both CSC's should be pre-installed on the device.
Try this - Go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press dial, you should see a screen with the list of available CSC codes for your device. Select the CSC that you want and tap the Install option.

The Samkey method would only work if the security patch on your phone hasn't been updated past July 2020. Otherwise you will get an "unsupported BIT" error.

In this case you're stuck (like myself) with whatever csc you currently have unless you root your device. I haven't rooted any of my samsung phones (my primary handsets) since my S3 days as I had no need to. So I'm not familiar with the process for sammy devices.

I see. definitely there is some compability issue from coverting color os to oxygen os. Maybe switch back to coloros for now just switch to english and install google services that way? at least you will still have 5G and google services at some time and benifit from using chinese local services in china like subway card service or chinese map service?

Question Indian firmware with European Z FOLD 4 (SM-F936B)

I just saw online that India Market got the new update (F936BXXU1AVIH) with September security patch.
So my question is, as i have an european model with the same model number (F936B), what is the risk if i flash this firmware ? As i know that it's not gonna change my 4G/5G bands anyway, so i'm guessing maybe an OTA issue after flashing this firmware (like not receiving them as i don't live in India).
Sorry if it's a stupid question :-/
No risk, CSC HOME and all good. I do it.
Ok, thanks for your reply
And what about future OTA updates ? Will it still be working ?
Yes.
Yesterday I installed the Indian version on my European version Fold 4, there is no problem except that it does not pass the Safetypass and I cannot make contactless payments.
No Root, no OEM unloock, just ODIN upgrade (firm from Sammobile).

I confirm that i can no longer make contactless payments as well, but i never used it anyway so not a big deal for me... i hope that there will be no others bad compatibilities like this one.
Will update on a newer European firmware later or just flash the AVIH European firmware when it'll be released

I'm guessing that it's caused by the software itself and not caused by CSC. Maybe in India, Google Pay is not used, i don't know...

It's very strange that the India version does not pass Safetynet's CTS checks. I also used the Home_CSC, I had never had a similar problem. I will wait to try with another region when it comes out.
Same here....Some week ago I bought a Z Fold 4 with EUX CSC and immediately changed CSC to INS using SamFW ver 2.1, Wallet worked like a charm until latest security update installed some days ago...Now, reverting CSC to EUX, does not solve the problem...

So you're saying that you reverted back to the last Eurpoean Firmware and that you can't still use GPay ? Or you just tried to changed the CSC without flashing European firmware ?

Maybe we have to wipe everything to get it working again when reverting
