Question Change carrier SM-S908U Or Change Firmware

Hello
This is the first time I write here, I bought a phone from someone on the internet a week ago as it is unlocked but it is locked on Verizon network and I am in another country in the Middle East and I spoke with Verizon and Samsung Care in the US they all told me that it is not stolen but requires data to unlock The first buyer, and I don't know her, is there a solution to change the firmware to another country and open it? How do I bypass it as soon as possible? I tried to install a ROM for Europe, which is SM-S908E, but the installation did not work, it says fail sha256 is invalid, and another version was installed through Odin
SM-S908U but nothing changed, is there a solution?

Flash the U1 firmware, hoping the phone was purchased from Verizon more than 60 days ago. You can't install other regions firmware in USA model, only U1 can be installed.

Question Looking for the SM-S908E/DS firmware on Sammobile and Samsung Firmware Downloader - no success?

Hello everyone!
I was using Samsung Firmware Downloader to try and download the latest firmware for my S22 Ultra; the SM-S908E/DS. When Samsung Firmware Downloader returned this error, I wondered why it wasn't working.I used the same firmware CSC as my phone (XSA) but apparently the SM-S908E/DS doesn't seem to have a match?

For reference, I used SM-S908E with the same CSC and that worked! Which was strange.
Has anyone else experienced the same problem? I have opened up a Github Issue but there has been no response thus far.

Try a manual search for firmware.

I went through the files on some of the sites - specfically samfrew, sfirmware and samfw. None of these sites yielded the firmware for the SM-S908E/DS - Dual SIM version, only having firmware for the SM-S908E.
It seems like Samsung doesn't show these, or the Dual SIM firmware is considered a subset of the Single SIM version. There are other phones where the Dual SIM version is a different model; like the Galaxy S5 Mini:
SM-G800H (Galaxy S5 Mini Dual SIM)
SM-G800F (Galaxy S5 Mini International)
I unfortunately have no idea what will happen if a firmware for the SM-S908E is used in the SM-S908E/DS. Probably best to not attempt it.
However, I do appreciate the help you tried to give me.

Thank you for the offer but this is no longer necessary. I have managed to find a solution for my problem.
Apparently, the firmware downloader does not take the "/DS" and the firmware will work for both the normnal and "/DS" devices.

Question Software change from usa to india

Hello there! Yes and no, you cannot change the model number, but you can change the CSC code to for example one where updates are received faster. I have 2 methods you can try (I have an SM-T290 which is rooted):
Method #1: Root Essentials app​1. Power on your phone if it isn't yet.
2. Open Google Play Store and download this app.
3. Install the app.
4. Open the app.
5. Give all permissions that are needed.
6. At the default 'Tools' section, scroll down until you find something like 'CSC code changer'.
7. Follow the on-screen instructions to change your CSC code.
Method #2: Phone by Google app (WILL ERASE DATA, atleast they say)​THIS METHOD MIGHT NOT WORK.
1. YOUR DATA WILL BE ERASED. So, back up your data.
2. Install Phone by Google (from the Play Store).
3. Open Phone by Google.
4. Dial this code:
*#*#27262826#*#*
5. Choose the CSC of your liking and tap on INSTALL.
6. Wait for your phone to reboot.
7. Enjoy your new CSC and the features that come with it!

That is the firmware for different countries. Every firmware has a specific country code, called CSC. I have for example a firmware from Thailand on my A12, and it's CSC code is THL (from Thailand). This can be changed, and I think it allows you to flash different firmware images (although I am not sure).

I thought of doing it by using odin....i have downloaded indian firmware will try flashing it with odin

Here's a screenshot showing it on Samfw:

Yes, that works. Checked another thread where someone flashed different firmware, and it was working correctly!

Okk thanks for the confirmation

What would be the benefit of this?

There are atleast 2 benefits I know:
1. You can get software updates earlier.
2. You can get some exclusive features, such as the option to record a call (As I can).

Question Not getting OTA updates on my S22 ultra (SM-S908U)

Hello,
Recently I bought an S22 ultra from unofficial source. I haven't got any updates from then. I think it's carrier locked. And it is not possible for me to use that carrier in my country. The phone's model number is SM-S908U/DS . In the software information page the whole model number is shown as SM-S908UZKATT. I want to update my device. How should I do it? I heard odin can be used to manually update my phone. But I don't know how to do it. Also I don't know where will I get official firmwares. Please help me ASAP.
Thanks in Advance. Cheers.

You might want to consider sideloading the latest firmware update.
But before that, you must
1. Find your Model name & CSC Code using Phone INFO ★SAM★ 3.8.5 or just go to about phone
2. Download your firmware using Frija
3. Flash the latest firmware using SamFw Tool

Hello edwaine, thank you so much for the help. I downloaded all the things you've mentioned.
I went to the Software information page in the About Phone settings and found out this...
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After this I thought my CSC will either be GCF or XAA, then I head over to frija and typed my model number SM-S908U and the CSC code which is GCF and then clicked on check update. It showed
then I thought the CSC might be XAA. So I typed XAA and clicked Check Update. It showed
am I doing it the right way? or do I need to search using my whole model number? (which is SM-S908UZKATT.)

Add "1" on the end of your model name. Your CSC is "XAA"

Okay on it now. And are you sure adding 1 at the end of my actual model number will be okay? Because I just went to my about phone settings and found out this
Sorry I am a super noob!

There are 2 Models for the US: The "U" which is carrier locked & the "U1" which is Carrier Unlocked. Your device as per the CSC belongs to the U1 model.

I mean you already tried it with SM-S908U and not SM-S908U1 and did not get any result.

Help! Cannot turn on mobile data while calling and messaging still working!

This is regarding the Snapdragon Note 20 Ultra, USA version.
I got a Note 20 Ultra Verizone edition where I flashed an unlocked U1 firmware. I suppose the required software information can be seen from this screenshot:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The issue now is, as I have put an Indian Operator (Airtel) SIM in the mobile, calling and messaging facilities are working flawlessly, but I cannot turn on mobile data. The WiFi works fine, but no mobile data. The SIM Information looks like this:
Moreover, whenever I try to open the SIM Manager, these four dots keeps loading and the screen just stays there:
I haven't taken a screenshot, but in the next screen the Data Roaming Option cannot be turned on also, I was just looking and turning on/off here and there.....
This is picture of the drop down menu, I suppose it won't be of any help, still posting:
Please let me know if there is any way to solve it....... Also let me know if any other info is required, as I believe I might have missed posting something.....Thanks!

One more thing, I downloaded the firmware from this link:
Download Galaxy Note20 Ultra 5G SM-N986U1 (XAS) N986U1UES4HWD7 in Samfw - Samsung firmware download

Before, I flashed this firmware, my software info was like this:
And, now after flashing the U1 it is like this:
I see the VZW (Verizone, right?) is still showing in the Service Provider Software info..... Have I f it up somewhere during the flashing? Should the VZW still be there after flashing the U1 version?

Yes, it is Verizon and it is not supposed to be there. You should see INS for Indian firmware/ SIM.

The problem is they released the Exynos version in India! I suppose I cannot flash Exynos version on Snapdragon, right? Also, the Indian rom had dual sim while this one is i physical SIM+ E-Sim.

Ok, little update.... I flashed the phone again with a VZW Android 13 firmware, and now the mobile data with my Airtel SIM is working flawlessly, even with 5G!!! But guess, as I'm not with a VZW SIM, the set will not receive any update now!
