I bought this phone from the USA about year and a half and I'm using it in Macedonia, Europe the whole time. It is a dual sim, but I'm not sure which country it is exactly from, Taiwan maybe I guess?
The model is SM-G935FD and the Baseband version shows: G935FXXU1APB6.
I tried updating it manually, but always says you're using the latest software version even though android 7 has came out a long time ago.
Can you tell me:
1. How can I update to android 7 ?
2. Why am I not receiving an update automatically, even though this feature was working when I bought the phone. I was getting regular updates automatically ever since I bought the phone up unti a point when the 7 came out.
3. If I update the firmware through an SD card or whatever method you suggest its best, will I continue receiving regular updates automatically after I install the v7.0 ?
4. How can I check what country is this phone from?
Lots of questions, would be glad if someone can clear these things up for me so I can understand better how this works with samsung and different countries models etc.
Thanks up front!
try smart switch on PC to update it... frend of mine had s7 flat and no update via mobile phone, as soon as I connected it to pc and turned on smart switch update came out...

I wanted to mention that, but I've probably forgot. I did try Smart Switch, but it also said, latest update already installed. Any other ideas?

I'm sorry for my noobish questions, but can you please explain to me how to choose the country of my firmware? Do I need to choose a country which I currently reside in? Or do I need to choose a country for which the phone was made? I just want to use English language, even though I use it in Macedonia, Europe.
Please kindly advise. Thanks!
1. How can I update to android 7 ?
i had the exact same problem as you smart switch n ota both said i was on latest software. All you need to do is goto sammmobile download firmware for your s7 edge model if your phone is non carrier or unlocked then you can download any carrier version. after that download Odin n Samsung drivers n view an odin flashing tutorial on YouTube.
3. If I update the firmware through an SD card or whatever method you suggest its best, will I continue receiving regular updates automatically after I install the v7.0 ?
I am getting all the 7.0 updates.
4. How can I check what country is this phone from?
if i remember correctly Its written on the smartphone box although u don't need to worry about the country all you need to know is the model number.
But to tell the truth there is no performance difference only ui change but still if u want to be on the latest version then use Odin. good luck.
I have flashed my s7 edge about a dozen times n haven't faced any flashing problem just be sure to use original cable n try not to use the computer while the flashing is happening. use odin in adminstrator mode n if possible kill extra background processes like chrome etc (not needed but i still do it just to be safe)

Just checked my phone with PHONE INFO app and there seems to be no CSC code?! All these field are empty:
Original CSC Code: blank
Firmware CSC Code: blank
Active CSC Code: blank
Available CSC Codes: blank
CSC Country: blank
I tried dialing *#1234# and it says:
"USSD code running"
but it shows some kind of error right after:
"connection problem or invalid mmi code"
and does not enter the menu with the CSC code. Tried restarting the phone, switching sim cards and what not.. Nothing worked and I have no clue what my CSC code is now.
My original box is gone and can't really see what country it was made for, but as far as I can remember it didn't say anything on the box. The title of the original amazon.com listing says: Internationally Sourced (Middle East/Africa/Asia) Version G935FD which doesn't say much.
I don't know what to do, I'm a bit scared to flash it with just about any country firmware. There's got to be a way to find more about this phoe CSC?

Download cpuz app from play store. From the app you will find what is your phone chipset. If it is exynos download any 935fd nougat firmware and flash it with Odin.basically 935fd is a unlock version. it's support all csc version and you will also get update how much I know.
I have an rooted Android 7 on my S7 Edge DUOS without issues.
I'm looking the rom for Oreo but there is not exist yet, I think...

Hello everyone,
I have a large issue here that I have spent the last 2 days trying to fix.
I have a SM-G935T that I had unlocked by T-Mobile to use with my current Verizon service. Once the device was unlocked, I see that the only way to use the phone with verizon is to flash the SM-G935U firmware to the device. Before the unlock, I allowed the phone (phone wasnt used for over a year) to download and install several updates to the most current 8.0 software for t-mobile. Apparently the SM-G935U firmware I had was an older version and the phone is now in a boot loop and the only thing I can do is get to download mode.
Whenever I try to get the latest SM-G935U firmware from Sammobile, it fails to download due to network error. I have a paid Sammobile account and decently fast internet. Not sure what I should do from here as the device needs the firmware that I cannot seem to download. The version I am after was the G935UUES8CSA1_G935UOYM8CSA1_VZW.zip
If anyone has any ideas of what I can do to get this device going again on Verizon, I would appreciate the advice!
Thank you in advance :highfive:

Hi all, (I previously asked this here.)
I have a carrier unlocked SM-G950U that was previously on T Mobile that I now have on Verizon, (long story, see below.) However, my device isn't updating, as seems to be the case for a lot of migrated SM-G950U(s). Of course, I want Android 9, and I also wouldn't mind getting rid of some of Verizon's bloatware. I was also fortunate enough to have received a research grant for some work in Italy, and I'd like to bring my phone along, (I'm a student.) So really, 3 reasons:
I want Android 9.
I don't want Verizon's bloatware.
I want to be able to switch carriers without the painful process of a carrier unlocked phone. (Ie., with the unlocked firmware my understanding is that I only need to restart my phone, as opposed to resetting my device, to switch carriers/SIMs in the carrier unlocked (ie., non-U1) device, (I think.))
I want to flash an SM-G950U1 ROM, but I'm not sure if this is still possible, (though according to here and here it was possible about 2 years ago, on different firmware/bootloaders.)
My plan is to do this:
Download this G950U1UEU5DSC1_XAA from updato. (I believe XAA is the unlocked region code. My device is already carrier unlocked.)
Flash with ODIN (3.12.3, as far as I know only making sure repartitioning is UNchecked.)
I have a Snapdragon device.
Will this brick my phone?
Alternatively, here says I can download any carrier version of G950USQU5DSC1 (except Verizon and Sprint,) flash it, and it will work. I think this only accomplishes my getting Android 9, however, as it is still a carrier branded ROM. (So I'd still have to deal with bloatware and (possibly) resetting my device to switch networks.)

Baseband Version: G950USQU5CRG3
Build Number: R16NW.G950USQU5CRG3
Long story of how I got a carrier unlocked (SM-G950U) and not unlocked (SM-G950U1) device:
I purchased my "new" device on Amazon through a third party about 3 months ago. I checked the model number and found SM-G950U, but a couple places online said that this was indeed a regular, unlocked S8. However, my device wouldn't update, and I could see that I was stuck on a mid July/August build of Android 8, (CRG3.) Now that the summer's getting closer, I need(ed) to make sure my device is going to work while in Italy, so I called Samsung to update it/make sure it would work. They told me my device was previously activated on T Mobile, unlocked, apparently refurbished and sold to me. I rechecked the Amazon listing and it was in fact listed as new. (It was alongside Amazon's own listing for the S8.) Unfortunately, after spending the second half of my day on support calls, I won't be able to return my device because it's been just over 3 months. Looks like my next best option is to update/maintain it myself.

Lss yes you can. I don't know the exact. But it is nearly impossible to truly brick a u model. But everything you show looks good. I think you need the modded odin for unbranded but you can Google carrier switching s8 and it should lead you right back to xda

Thanks for the quick reply!
I'll try later today with the G950U1 firmware. I've finished downloading the T Mobile firmware recommended by the second thread, (G950USQU5DSC1,) in case anything goes wrong, (in which case it looks like this firmware will positively work.)

See here: https://forum.xda-developers.com/galaxy-s8/how-to/rd-carrier-switch-root-snapdragon-t3597473
Just download the G950U1 firmware from Updato (or using SamFirm or Frija) and use that instead of the firmware referenced in the linked instructions.

So as a surprise to no one, this worked successfully.
Thanks for all the help!
Ultimately, I did have to deviate from the guide here, (the same one you linked and that I had above.) I needed to download a new patched version of ODIN, which I got here.
The process was:
Download PatcheD Odin
Launch PatcheD Odin
Put phone in Download Mode
Connect Phone to PC
Extract the G950U1UEU5DSC1_XAA firmware from updato. (The same link/URL as I have above.)
Browse to/find files in Odin and put them in the right places.
Start...
Wait a reasonable amount of time for the files to be downloaded to the device, and forever for it to actually update.
Profit, (and finish setting up the device, wondering how you're going to signin without your 2FA codes...)
So again, thank you everyone. If anyone comes across this thread in the future you have my steps.
UPDATE:
I need an urgent help however.. I changed my csc to SPRINT from ATnT, using *#272*IMEI number# method. I kept changing to T mobile, and all, until I got stuck with SPRINT.
Now I tried the *#272*IMEI number# method and it won't let me do it with SPRINT CSC.
HELP please ( I just want to go back to ATnT or T mobile again..
Hi guys,
I just gave me iphone xs max to my wife since her iphone 7 is already too buggy and slow. Now that I moved to s10+, I love it and but the customization option is overwhelming me. Happy though that its customizable.
Then I realize 1 critical thing. I bought a snapdragon USA version of AT&T from local importer. I am located in Asia. When I looked at the software version, its only at "G975USQU1ASD3" with security patch, March 2019. I tried for 2 days now to get the OTA update and it just wont come. Saying that I already got the latest update.
Naturally I checked google and found so many updates, and one of them, night mode in camera, I really want. Now I am a newbie in all of these. My question is.. how do I get the non OTA update? I don't have a PC, but I might be able to use my work PC. I do have an micro SD card.
In summary:
1. Where to find the update files? the non OTA version
2. Is it doable without PC?
3. Can I just jump to the latest firmware update, or do I have to do it manually one by one?
4. Will it wipe my phone, because I spent hours customizing it before checking the problem.
Thank you very much if there's anyone willing to help me figuring things out.
regards,

1.You can download firmwares on sammobile.com for your model
2.You can use work PC but need get small software named Odin and samsung drivers for correct work
3.You not need install one by one you can flash directly to latest one but must use HOME_CSC and make backup with samsung app named smart switch which is already on phone if not you can get it on Google Play Store

To try and force a change of the csc power down your phone, remove the SIM card and boot up your phone without any SIM inserted. After the phone has completely booted up insert your SIM and you should get a message that the network settings are being updated.
I purchased an unlocked AT&T S10+ as well to use on T-Mobile. Since you don't actually have AT&T service I would very strongly recommend that you flash the U1 (unlocked) firmware. There are instructions for doing this in another XDA thread.
AT&T firmware is modded specifically for their messaging, network and WiFi services. Since I'm not an AT&T customer I got no OTA updates until I flashed the U1 firmware. Immediately after flashing the U1 firmware and booting up OTA updates were available to download and I receive OTA updates when they are available so there's no further need to manually flash updates using a computer.
The current U1 firmware has night mode for the camera and was just updated this week to the August security patch (which is good for Samsung).

Hi thank you very much for your help. I appreaciate it. However, as you can see from my opening post, I kinda did a mistake and locked myself out of AT&T now.. I am stuck with Sprint after changing CSC 3x feeling safe.. then Spint removed my ability to change CSC via *#272*IMEI#
:crying::crying::crying:
You shouldn't need to change the CSC using the dial code. If you cold start your phone without a SIM card then insert the sim after your phone has fully booted up you should get a message about your network settings updating.
I would also still recommend flashing the U1 unlocked firmware.

Hi thanks again for replying to me. I tried many times doing this but as soon as my SIM card got in, SPRINT OMADM took over.. I can't even get rid of the notification.. sigh..
This might help:
https://forum.xda-developers.com/sp...-to-remove-sprint-omadm-notification-t3636264
That's apparently something annoying that's specific to Sprint.
To get rid of any US carrier stuff on your phone I would still suggest using the modified Odin (which can be found in the XDA firmware flashing threads for the S10+) and flash the U1 firmware version which is carrier free.
Hi all,
I have an S10+ that refuses to acknowledge that its software is out of date.
I bought a US Cellular Galaxy S10+ from the Samsung website when the phones launched in March 2019. In late August 2019, I decided to switch to AT&T (had previously been on my parents' plan, wanted to start my own). I transferred the phone and my number over to AT&T.
Recently, I noticed that I have not received a software update or security update since before I switched. My Android version is still 9, my kernel is dated Aug 7, 2019, and my security patch level is Aug 1, 2019.
No matter what I do, my phone says its software is up to date.
I took the following actions:
Called AT&T to have them update the phone in their servers or whatever it is they do.
Changed the date in the phone, restarted and searched for updates.
Cleared the cache data in the phone's BIOS.
Tried using Smart Switch, it said it was up to date.
Did a factory reset of my phone.
Contacted Samsung, was told to talk to my carrier.
Called AT&T again, was told they could not push the updates because the IMEI number is for a US Cellular phone, not an AT&T phone.
Today, I took it to a Samsung representative at a local Best Buy. He plugged the phone in to whatever PC tool he has, it prompted him to download the latest AT&T firmware. He did so and tried flashing the phone. I looked and saw the blue BIOS screen where the phone said it was downloading the firmware. However, when it finished and he started the phone up again, the phone's software information was unchanged. He tried it a second time, and still no change. He told me he had never seen a phone refuse the firmware like this, and he said there was nothing he else he could think of to try. He said even if I could flash the firmware, it might still refuse to receive updates and I'd have to keep flashing it to get all the updates. His suggestion was to just wait and try to see if I could get a deal on an S20.
This phone is paid off, and still in great condition. I'd really rather not have to replace it less than a year after I got it. I've thought about trying to flash the phone myself with Odin, but I'm not sure whether I need to try it with AT&T firmware or US Cellular firmware. Furthermore, I can't find AT&T firmware for the SM-G975U, only the SM-G975U1, and I'm not even sure if it's up to date. What are your suggestions?
You could try updating using the Frija & Odin method found in News & Discussion board, then see if next month you receive OTA?

What does it show for you over there?
Your phone is probably still on the US Cellular CSC.
I'd recommend flashing the G975U1 ATT firmware if you want ATT features, or the XAA firmware, to convert your device to a completely unbranded variant with no carrier apps.
You can use SamFirm or Frija to get the firmwares.
Use 'SM-G975U1' as the model and for the CSC, use 'ATT' if you want the AT&T firmware, or 'XAA' if you want the unbranded firmware.
Flash it with patched Odin here:
https://androidfilehost.com/?fid=6006931924117912211
You will have to wipe/reset the entire phone with this process, so make sure to use Smart Switch to backup your data.

You will have to wipe/reset the entire phone with this process, so make sure to use Smart Switch to backup your data.

Hey, thanks for the advice.
My service provider software information version is:
SAOMC_SM-G975U_OYN_ATT_PP_0039
R58M20FYAKW
ATT/ATT/USC
I've looked at both Frija and SamFirm/Updato. Frija doesn't seem to recognize ATT or OYN as a CSC for me when I try using it in the auto search for either SM-G975U or SM-G975U1. Updato has an AT&T firmware, but it's from Nov 2019 and is still Android 9. SamMobile claims to have more up to date firmware, but their download links always send me to the registration page, even after I already registered (I'm guessing they're not as free as they claim to be).

Ah, it seems like your device has switched to the ATT CSC but remained on a US cellular build, resulting in there being no available update file on the ATT server.
Download the XAA unbranded G975U1 firmware with Frija.
I completely forgot that ATT doesn't host their firmware files on Samsung servers, instead it uses its own servers for updates.
Updato and SamMobile are both greedy and want you to pay for uncapped download speeds so I wouldn't recommend using them.
With patched Odin can change the csc? I have G977B and cannot change the csc.

Only applies to US variants when switching from G975U to G975U1.
It's 'patched' as it bypasses the model number check.

Thank you.
It took me forever to find someone with this problem / solution.
I switched from Verizon to Xfinity Mobile and had not received a security patch since Oct '21 and was still on Android 11.
You'd think that this problem occurs often enough that support would know the solution.
Xfinity Mobile told me Samsung was responsible.
Samsung (Best Buy Geek Squad who is certified Samsung Service Center) said Xfinity Mobile is responsible but gave me the idea that the phone might be 'stuck' on Verizon so it can't pull the updates from Xfinity Mobile.
The build was from Verizon.
I installed the latest build from Xfinity Mobile (CHA) for this model phone (SM-G973U) so it now has Android 12 with Dec '22 security patch.
I'm guessing that the updates will work now but I won't find out for 3 months since the S10 is now on quarterly releases.
Thanks 2x.
Scott
