[Q] G901F - future non-branded ROMS via OTA possible?

I would have posted this under the S5 'T-Mobile' section, but I think it might be more of a generic discussion.
I am considering in purchasing the S5 Plus (G901F). From what I can see right now, this is only available in Germany, UK and just about now, Netherlands. Problem is that it's exclusive to respective providers and therefore - "branded"
I can find it cheaper from Germany - which is subject to T-Mobile / Telekom (same thing?) branding.
I have asked the shop and they confirmed that the phone is factory unlocked to any provider/country and that there is no "hardware branding" on the phone. Meaning no stickers, no logos or anything else physically on the phone.
However, there is "software branding". Meaning the firmware itself and whatever bloatware the provider has put inside that ROM.
Now, I have read that I can use ODIN and find the least crapware-loaded ROM (from any country) and flash it *without* compromissing the knox bit. So far so good.
What I would like to know is that: What happens when finally Samsung releases a pure, non-branded ROM for the G901F? I can still use ODIN to flash - no problem. But what about future releases. I mean future non-branded firmwares. Would I be able to use OTA from that point on, or would I have to keep an eye and update via ODIN? Can someone please elaborate and explain this?

I get it - that's a 'newbie' type of question, but I would be really grateful towards some help here. All I can do for someone who will spend 2mins for writing a useful/accurate answer is say 'thanks'
Didn't find an exact answer to what I ask here, hence me writing this. Hope it's not a double-post!

Hi jstoner,
I think that while using an unbranded ROM would probably prevent you from receiving OTA's from your provider you would still be left wih the Samsung tool for getting new updates - Kies.
It has the options to check for updates and to flash them.
The geeky option is indeed to keep your eyes out for updates and fire up Odin
Disclaimer: I never used Kies to update my phone so I might be wrong here
Sent from my Android powered Tricorder

I forgot to mention - I live in Greece (but I m thinking of buying the phone from Germany, as it's not available here yet)
Does KIES list all ROMs from ALL regions/providers for a particular phone?

Hello,
It seems there is a firmware for Greece for you

Oh good
Does that mean it's about to be released in Greece soon???

Nobody knows man. But you can always flash the newest updates via odin without triggering knox. After a few month only German Vodafone is building an update. T- mobil stii stuck on h5 firmware. So if there will be an unbranded oce ever ever ever.........you have odin

Wonder if that Greek ROM is unbranded or not
As for hardware branding, it seems that all G901F units sold in Germany under Telekom/T-Mobile have that "LTE+" at the back (also on the retail box). Instead, those EE (UK) units seem to have no hardware branding at all - it just has the "Samsung" logo at the back cover (and nothing on the retail box)

There are a few Providerapps inside. All Roms i tested for 901F has the normal Samsung Bootloaderscreener. No Provider startup. So nothing to worry about . Mine has also the LTE+ logo, but former T-Mobile Devices have also Coverbrands on it...Thanks God these not

G950FD from Iran (THR) with pre-installed Persian/Iranian Calendar

I bought an unlocked G950FD which turns out to be CSC THR (part of OXM) so should mean it's from Iran. I have found it generic enough in almost every way to be used internationally (in English) with two noticeable exceptions that i'm trying to solve.
1) there is pre-installed Persian Calendar in the OS which appears after the Gregorian date on the AOS and lock screen. I also noticed this extra date appearing on the Samsung Calendar app under the western date, but i don't use this app at all so can easily ignore. The AOS and lock screen is seen all the time and would displays: "MON, JUNE 5 (KHOR 15)". I looked through every settings on the phone and many forums online, and there is no software way to turn this off.
I thought a potential solution would be to replace this stock ROM with another region since any of the multi-CSC OXM firmwares should be compatible with the phone. So I tried to flash another region using Odin. I tried Singapore (SIN and STH) and completely reset/wiped the phone two separate times. However, despite flashing a large (almost 6GB) file onto the phone it still remains in THR when i looked in settings. I guess I misunderstood the purpose of different firmware regions, I thought i would be changing my phone's existing firmware to another region and get a different set of default apps and localization behavior. But the Persian date is still there on all the same screens.
Am I flashing the rom incorrectly? Is there some setting that i omitted that would give me the desired result of a Singapore OS? Any other ways to change CSC and get rid of unwanted parts of a regional firmware?
2) Another problem is when i receive calls on my local sim card, the phone number shows up without the country code, but if i store my numbers (on Google contacts) in "+<country code> <phone number>" format then the contact is not linked to the incoming call.
Apparently this is fairly common with international phones being used in another market. There is a workaround where i can edit my numbers on google to not have any numerical country codes but instead use the flag drop-down menu on google to indicate country associated with the number. I'm ok with that solution but is there another way? Would flashing a regional firmware that is my location solve this? The region that i intend to use the phone is not part of the OXM multi-CSC list of countries since they only sell the snapdragon variant here.
I would like to find solutions that would avoid root and custom roms, but if that is the only option here, i am not against going down that route.
Thanks a lot in advance.

My eventual solution and what i've learned.
So as i described above, i tried to flash many different versions of G950FD or G950F firware with multi-CSC OXM, but never saw my CSC change from THR. Nothing changed on my phone despite installing large files through odin which was always confusing to me. For the record, i tried BTU (UK), STH (Singapore), and SIN (Singapore) which are all part of the OXM.
I learned from another forum that the sim-card installed matters, so i was just trying different non-middle-east regions by picking UK or Singapore but my actual home region does not support this model/cpu variant. I don't have a sim-card from any OXM regions, only Hong Kong and US ones.
Then i found an old Australian (Optus) sim card from a trip and found a G950F firmware version with CSC OPS on Updato. Not part of CSC OXM but same PDA/Phone version and was told it's safe to flash. When i flashed that firmware with the AU sim card installed, i got the AU OS and all the old regional apps were gone. I got some Australian ones but nothing i can't uninstall. My caller ID problem also seem to be fixed. So i consider the problem fixed.
In all of this, the PDA version numbers were always the same (AQDG), so i'm still a bit unclear as to what the CSC file is specifying and doing.
Am i correct to assume that multi-CSC OXM firmware contained regional apps/settings for all the various regions but without a sim card installed to tell it which one to pick, it kept selecting the factory region of THR? And when i flashed the Optus firmware, did i really need the sim-card installed? Would it have changed the firmware to OPS because it's outside the multi-CSC OXM group?

You live in Hong Kong, right ?
I do too, and have a UAE S8, and Samsung Pay doesn't work.
Does your working around things allow you to use Pay, or you get stuck on the splash screen as well ?

Yes i live in HK, so with the AU Optus Firmware I got a AU version of Samsung Pay with all AU ads and suggested businesses. I can get past the splash and login using my normal Samsung Account, which shouldn't have a region. BUT so far i haven't had any success adding any of my HK credit cards, i assume it's a version compatibility issue. There is no way to pick which regional version of Samsung Pay on the Play Store, so i guess it looks at your phone's origin to determine that part of the app.
I am not that keen to use Samsung Pay, but of course interested to know if it is possible. It says to call the banks to get my credit cards added, so maybe there is still a chance and i will post if i do succeed.
Do you think Samsung Pay is particularly good for HK? Would using Android Pay be comparable here? I'm not that experienced with mobile payment apps in the past. Seems like the membership card storage function will still work on my Samsung Pay so at least i have that and can slim down the wallet a bit.

Hey there buddy,
Finally found a thread that represents my problem also, in my case i have a s8 G950FD that shows the same thing on my lockscreen, by me it shows (KHOR18)!
Is there any way around it, i mean a fix?? I would greatly appreciate any help

Yes that's the Iranian calendar date so the day will increment everyday. Khor is abbrev for the current month.
Yes I have a solution (read my second post in thread) but involves flashing with a sim card and 950f or 950fd firmware of the same region as the sim card. You will need to reset and erase phone data.
If you need help flashing stock firmware there is a long thread on this forum and where I found the answer about how the sim card installed might make difference.
What region/sim are you currently trying to use your s8?

Hey there again,
Thank you very much for the time. I am in SE Europe, to be more precise Republic of Kosovo. My SIM is from Kosovo ( we are considered i believe to be in Europe carrier wise)
I do need help flashing the phone as i have no experience whatsoever i just recently switched from Iphone to Samsung, this being said i must also mention the fact that i would definitely need help. I dont want to mess up the phone i just got it like 2 days ago

Things to consider:
- You can flash both 950F and 950FD firmware on your 950FD.
- You need to find your desired firmware. And that region needs to match your sim card, use Updato or SamMobile but the firmware package is a >3GB file and takes a while to download. Make sure you only look for versions for model 950F or FD.
- You will need to download Odin and Samsung usb drivers to flash the firmware onto your phone. Follow the thread "OFFICIAL STOCK Firmware-update (Odin) thread Samsung GALAXY S8 SM-G950F" for the guide.

If you decided to go the "SIM card CSC" method then follow this step by step:

Yes, if you are changing country/code of CSC, then the system needs to recalculate the partitions.
And don't forget no short cuts! Every step should be done.
Good luck.

ooo man this things is killing me now the problem i have after i have rooted the phone is that the computer wont recognize my phone in download mode ??????????

Hey Peeps,
Small update on how things are for the time being. I have been following all steps as described with odin. Last night i had issues with my laptop not recognizing my phone in download mode, got rid of this issue by changing laptops. Once the procedure was finished i ended up with the same thing on my phone???
I have flashed a european software ( from france) but still no go on removing or changing the region!!!
To be honest dont really know what to do again help is appreciated since that date thing is really annoying

Still on B124. Huawei is slow to roll out updates it seems. Not even available as an 'early update' through the HiCare app.

I am still on B121 and no notification of updates even though I check every day.

Guessing it depends on your country region .Anyway there is not much diff notice before and after update .

Ppl, does anybody had problems with this phone, now it's a little bit better, something I'm not doing anymore probably, but when I changed predefined apps on my phone I had to restart 2x a day the phone, huge lag and locking.
Had to shut everything to keep it simple...

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.

S10+ Appears To Be Incapable of Software Updates After Switching Carriers

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?

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.

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:

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
