My phone is on G928VVRU2BPD4. It's a Verizon carrier unlocked phone I currently use it with AT&T I'm on marshmallow 6.0.1. Since I use it on AT&T I cannot get any Ota updates I have to use odin. My question is can I switch it to AT&T firmware? Also is the AT&T version root able if I am able to switch it?
Unfortunately no.If y had an....lets say g928f carrier locked then yes switching is easy but since you have an g928v (the v at the end stands for verizon) you cannot change to another firmware since its a verizon model and there are no other firmwares for it.
I recently activated my SM-N910A on my new T-Mobile account. The phone was out of contract, so I asked AT&T to unlock it, and they did. The phone is working properly with my T-Mobile SIM card, albeit on the AT&T firmware.
Is it possible to replace the AT&T firmware with a stock Samsung Firmware, or, at the very least, with the T-Mobile branded firmware (for SM-N910T)? I understand that the bootloader is locked on these AT&T devices. Is it possible to unlock the bootloader and load a different firmware onto the device?
AT&T firmware has SO much bloatware, and I've not had any luck finding a way to root the phone on this firmware, so I'm stuck with all that bloat. What are my options here? Thanks!
EDIT: The phone was updated OTA to Marshmallow (6.0.1) when it was on the AT&T network. Build number is MMB29M.N910AUCS2EPH7
So I got an ATT S8 the G950U version. I unlocked it via ATT with their unlock code.
since then using it on Indian carrier Airtel. I am not been able to get any software updates. Whenever I check for the updates it says its up to date. But its stuck at build number G950USQU1AQC9 and security patch of 1 march 2017.
How do I update this? Do I need to flash ATT software via ODIN? but I need to retain the unlocked status.
You wont get OTA unless you have an ATT sim in it i Think. Just flash G950U1 firmware which is the unlocked version sold by samsung.
I bought a sprint s8 and flashed G950U1 firmware and using on Airtel. Moreover you wont have any carrier bloatware.
It seems Smart Switch also updates when applying initialize. Not connecting your phone before starting up SS gives you the option to input model - and serial #.
And to my knowledge, once unlocked (free to use any SIM) stays unlocked.

Did you flash it with Odin? AFAIK its the only way for snapdragon models. Been away from android tinkering for a long while. Can you point me to relevant threads?
P.S. Are you able to get OTA now?
I have a similar issue but in the UK. Can't see OTA updates and it says up to date in Smart Switch. Is flashing the stock firmware risky or break knox? What are my options?
Search Updato.com for the latest G950U1 firmware. (XAA version is the best region to use in your case). Use THIS version of Odin to flash: http://dl.psouza4.com/android/Odin3_v3.12_PrinceComsy.zip
You will not get updates normally if you don't. Your phone is trying to contact AT&T servers but you don't have their sim card so it's not going to let you download it.

Be careful, the latest u1 firmware is a rev2 bootloader. It will probably be rootable like the n8 one is but no one has confirmed yet. There are also no ready to flash rooted ROMs with it
Root is worthless anyway.
Hey Everybody,
So I've come to realize that my unlocked US S10+ on AT&T didn't have VOLTE or Wifi calling as options in the communication/call settings menus. this is pretty disappointing as it seems that using the unlocked phone with Verizon you get these features, and they make a decent impact on my use of the phone.
My understanding is if I flash the ATT firmware to the phone I would get the functions, so being an amateur I followed some simple guides to SamFirm AND ODIN, and downloaded the ATT CSC firmware for my model number. However after going through the Odin process and resetting my phone it is still showing the same Software information as prior to my installation, and I do not have the features.
I saw a thread on the board stating that the ATT firmware isn't available yet, so I'm not sure if what I downloaded was actually any different than what is on my phone,and my phones "Service Provider Software Version" did already have ATT in the description, which is a bit confusing to me.
Am I correct in understanding the only way to get the features would be through a firmware flash? And would anyone know if I had flashed the right firmware, and what the original firmware CSC would be for my model if I needed to revert?
My information is:
Model Number:
SM-G975U1 (S10+ ceramic white 512GB - Unlocked US)
Service Provider SW ver.:
SOAMC_SM-G975U1_OYM_ATT_PP_0018

If it's anything like the S9 was, you can't just ODIN the firmware/CSC. You'll just get the bloat with none of the features you want.

I've heard this as well. If you want those features on a Samsung phone, it has to be at&t branded. I ordered an at&t phone from Samsung since I make good use of wifi calling. It works fine on my unlocked P3XL but no dice on the Samsungs.
I have the same phone and service and when I went to update my imei they told me it could not find the phone. So I was without lte/4g for a day until I gave them a imei to a s8 active. Now I have data at least

So I have the same service provider software, on my unlocked s10+, however when I went into an ATT store and looked at a branded S10+
I noticed the service provider software version to be : SOAMC_SM-G975U1_OYM_ATT_PP_0033( thirty three at end),
so anyway to update the service provider version? does that come from the SIM ??
I have an unlocked S10 plus and I flashed the AT&T Firmware. I now have VoLTE and WiFi calling unlocked on my phone using AT&T. You need to make sure you flash the U version of the firmware, not the U1 one. Unlocked S10 is using the U1 firmware already so flashing that one again changes nothing.

Where did you get the att firmware?

I kinda doubt it but did any of you with unlocked phones that flashed the AT&T firmware get any better service? I've been considering it to get VOLTE but just wondered

I followed this thread https://forum.xda-developers.com/galaxy-s10/how-to/att-ota-ota-updates-t3909697
At first like you I downloaded the wrong version and nothing changed. I finally flashed G975USQU1ASBA and now have VOLTE/WIFI Calling and of course all of the bloat. But at least those two functions are working. Make sure that you complete a clean flash when I did a dirty flash I had problems sticking on the loading screen.
I believe you just need to call in ATT to take care those carrier specific features .
Which firmware can I flash with Odin to my S10+ Xfinity Mobile unlocked to get AT&T OTA updates? Currently have ASF7 flashed from the latest unknown firmware uploaded to Sammobile. I flashed w/o USERDATA. I just want to be able to get future OTA updates as I just switched my carrier from Metro by T-Mobile to AT&T. I was using U1 US unlocked firmwares on my Note9 & S10+ but want to use carrier perks now with AT&T.
What's with AT&T being the only ones to not release update files? You would think they all would be required to release them. More AT&T customers need kick up a fuss about it.
I have two carriers, ATT & Verizon,
I have tried the Verizon chip in my unlocked ATT S10+ (SM-G975U) and only time it ever work some what is when I was at the Verizon Store.
Because of that issue I tried to flash it with "ODIN" with the latest firmware that supposed to be for the Unlocked version, after flashing I still see that ATT LOGO & apps on the phone.
One thing I noticed; while it was restoring it choose "HOME_CSC" instead of CSC that I have choose.
ODIN was on Default settings.
Do you have a guide I can follow to flash the S10+?
Are there pre-rooted custom firmware for the S10+?
Thanks
