change firmware of S21 5G - Samsung Galaxy S21 Questions

hello everyone,
am french
I currently have a S21 5G SM-G991U but it appears it not work for french SIM,
so I don't know a lot about phone but I think the best solution is to change my firmware from SM-G991U to SM-G991B
aniway, i download that one https://samfw.com/firmware/SM-G991B/XEF/G991BXXS6EWBB but it don't work when i flash it with odin
I either have "SHA256 error" or with a patch version i have "<ID:0/004> Re-Partition operation failed."
Is there a solution to this problem or a better way to solve my initial problem.
Thanks a lot !

Hello!
Did you manage to flash the phone with this firmware? I have the same issue with my sim card.
Or maybe there is another way to remove the simlock?

Hi MrZ3T4. It's possible to change on S21 5G the firmware from G991N (Korea) to G991B (spain) with patched Odin whitout brick it? Chipset is Exynos 2100 for both..

Need help debranding LG Uplus(LUC) to (KOO)

Hi, I just got Galaxy S9+ and it is bloated with LG Uplus menu and apps. Model version is SM-G965N and when i look for firmware in Sammobile only few firmwares are shown. (KOO, LUC, SKC, KTC)
Can I download KOO firmware and flash with Odin to get rid of carrier bloats and return to stock?
I heard that S9 and S9+ have some problems changing CSC. But if i flash like this, would it be considered changing CSC. Would it work to flash with odin like this?
Is there anyone who knows answer to this?
I also want to do the same thing on my s9 plus. can anyone help please ... thanks

just so i have this straight, youre using a Samsung S9+ on a LG cellular service? thats awesome!! the 965N has the Exynos processor, to the best of my recollection, and you can verify this by installing CPU-Z. If it is, you should be able to flash the G965F firmware on it. I have a S9 that i got from Cricket and installed the G960U firmware on it, debranding it and im satisfied with the result. You will likely need the patched version of Odin in order to flash any firmware on it to debrand it. Verify the processor via CPU-Z and we can go from there

G965N with LGU + firmware too And I want to unbrand it too.
i did it already, and went back to stock.
the service guy installed twrp, then installed custom rom- based on 965F/DS- everything was fine. except no 5.8ghz wifi connection, no OTA update menu.

[Help] Please help me identify firmware for this unknown version of galaxy s9+?

Hi all,
I bought this snapdragon version of s9+ in canada and it says sm-g9650. It came with Chinese version of samsung apps. I researched on XDA and found out that this might be hongkong version, so I followed this guide at https://forum.xda-developers.com/galaxy-s9-plus/how-to/g9650-snapdragon-csc-change-stock-t3815136 and i tried to flash G9650ZHU2ARE6 version(ZTO)
But I get secure check fail pit error.
Again , I researched on Internet to find out that this error occours because of mismatch of pit file.
Now I am confused about which firmware to flash.
I just want to get
1. All apps in english
2. VoLTE working.
Please find attached images of my device:

Looks like South American version, maybe?

Hi mate
For what i know you can only change the CSC to those CSC's available in the current ROM installed in your phone , An U variant is the snapdragon version for USA (?) it will not have a european CSC available .. and you cant flash an european rom either ( exynos).
So no , no luck to change to a european CSC with the U variant , sorry

Question S23 Ultra Change CSC

Hi there,
I have newly bought a S23 Ultra SM-918N model from South Korea. I live in Turkey and want to change to SM-918B model firmware because there is no Turkish option during setup. Changing on andorid settings will remain some English apps. Is that possible without unlocking the phone via Odin?
When I try to flash SM-918B stock rom via Odin, with Re-partition option is unselected, it gives PIT error and FAIL to flash. Is there a way to change the firmware from SM-918N to SM-918B any European one CSC?
Thank you.

You can't flash firmware specific to one device on another.

I thought that they are theoretically same hardware so that it should work. So you say that even I change the pit file on Odin or any other program, I cannot flash SM-918B firmware to my SM-918N device

Chances are if you mess with the PIT you'll brick your phone & it will be a JTAG job. How badly do you want to brick your new toy ? ;-)
You tried to flash, it failed. Yes, that's exactly what I'm saying.
its the same when i had a s22 ultra from china it looks like the phones from china or korea are software locked or something nothing would work to change the os from another region couldnt even use some of the secret menu codes to change the bands

Question Flashing europe firmware on a usa model

Hello,
I have a S23 Ultra ( SM-S918U) - USA model with at&t boot logo and I'm using it in Romania, Europe. So far so good except a few settings specific (maybe) to usa firmware: the missing data icon on notification list, missing network mode ( I can't manually switch from 5g to 4g).
1. Can I flash an europe firmware from sammobile via odin (SM-S918B - I think) over the usa firmware ?
2. Will I lose e-sim doing the above ?
3. What are the disadvantages of doing the above ? I read somewhere about high battery consumption
Also, on Sammobile there is no RO firmware. What firmware should i pick ? This one ?

Absolutely not. If you try to flash the BL and CP files from a different device variant, you risk a permanent brick.

Since the phone would be bricked, yes

Again, you could brick your phone.
The best thing to do is use multi-CSC U1 firmware, such as OXM. This probably won't be necessary though as the US firmwares typically overlap with many other CSCs.
Flash S918U1 XAA CSC using patched odin. You can't flash S918B firmware on it, odin will fail right before it flashes anything. Use HOME_CSC to preserve data and eSIM.
Patched Odin 3.13.1
For those looking for a modified, modded, or patched odin that is a newer build than all the fake and renamed prince comsy 3.12.3 versions floating around. I patch recent Odin versions to offer similar functionality to the princecomsy; in that...
