AT&T Branded S8 moving from AT&T service to Verizon - AT&T Samsung Galaxy S8 Questions & Answers

Hi,
I have read through a bunch of threads but have not seen my exact situation but I think I know what I have to do but want to get some advice from the experts here.
I purchased an AT&T branded phone an activated on AT&T a year ago. We needed to switch to Verizon so I got the unlock code from AT&T and switched no problem. As part of the switch Samsung has a BYOD feature that changes some of the software and menus from AT&T to Verizon. It was actually pretty cool because it removed the ATT apps loaded some VZW instead. Below is a link that describes the feature if you are not familiar:
Enjoy the Freedom of BYOD
So all is mostly good except I believe the menu change to update the firmware OTA is pointing to VZW and not ATT. When I run the update check it just says no updated needed. Looking at VZW they have updated their latest OTA version on August 1st here G950USQU5CRH1 so I know it is not trying to update to that.
ATT just released their version today August 30th here G950USQS5CRH1 but that is not updating either.
I will try this again over the next couple days to see if the updater is smart enough to find the ATT version but I am guessing I am probably in no man's land and will need to update manually using SamMobile or Updato or something else.
Any thoughts are very much appreciated.
Thank you.

I have tried a number of things like all the Verizon tools, Smart Switch, etc. and nothing will trigger a download.
I am downloading the only file from SamMobile that looks like the same version on the AT&T site but is says it is Verizon hopefully that will not matter. I will try to flash it with Odin and see what happens.

As an alternate I chatted with Samsung and they gave me the address of the a Best Buy in my area that will update the firmware for me. I guess some of the BB have Samsung techs in them. Kind of a pain but at least there is a back up.

Not sure if anyone is following this but I thought I would close this out. All options have failed.
Not even Samsung at Best Buy can flash the firmware since in their tool my phone shows up as VZW/VZW/ATT. So what I thought was a cool feature of the BYOD changing carriers only cripples the phone from an Update perspective, what a bad design. I would change carrier firmware as in some of the guides here but the problem is that I do not have G950U1 or G950U2. I have G950US which the older guides do not address.
I am either going to buy a prepaid ATT card but I hate to give those horrible people another dime or I will sell this phone and maybe just get Samsung branded like others in my family and they get updates from Samsung or go get an iPhone. I dislike iPhones a lot but at least Apple does not let the carriers screw around with their firmware.

Solved! Not sure why this site never showed up in my previous searches here or on the web.
https://samsung.firmware.science
Found the latest 2 OTA updates and applied them perfectly.

Well I can't say I've ran into this problem, but I to use ATT and am looking to eventually move to VZW, so I really appreciate your time and effort in making this thread as this isnt something I would have thought of myself. Also, that website is kick a**! thanks for sharing that

I was an ATT customer for 14 years on my wireless. The migration on the family 2 iPhones, 1 Samsung unlocked S8+ and my ATT S8 went perfect. I am the only one that had the firmware update problem because the other devices get updates directly from Apple of course and Samsung for the S8+.
My experience so far with VZW is excellent! For our family plan it was a little cheaper but our main reason fro moving was the network quality. Verizon in my area is so far ahead of ATT it is really shocking. Great call quality and data and coverage is fantastic. We had so many problems with ATT not sure why I stayed so long. They gave me a piece of junk Microcell to try and fix the issues at my house but even when we go to the ATT store that is 1 mile away, they do not even get wireless service in the store. They all have to use WiFi calling.
I have to really be impressed to recommend a company but VZW technology is well worth it for me. We will see how the rest to the customer services is.

What happened with the firmware you flashed with Odin? You can go to Updato.com and Download G950U or U1 firmware which is MUCH faster than the hours Sammobile takes. With newer firmware you can flash any carriers firmware (Go to Updato and download VZW firmware for example) because your phone installs the necessary files depending on the sim card you're running. Been that way for quite a while now.
Be careful with Firmware science as some of those builds aren't what is released so when a newer update does drop from VZW you wont get it again because you have a conflicting build number. Then you'll be back here asking why. Also, every time there's an updated firmware on FW Science you'll have to reinstall everything as flashing that update.zip wipes the phone post install. It gets really old.

Hi thanks for your input, I have 1 question to you, as I understand from your post you are talking about if mobile is already on VRZ firmware but have issue with OTA update? am I right? if not could you be so kind to tell me I'm on AT&T firmware G892AUCS3BRG1 (AT&T OREO Firmware) can I somehow switch to VRW or some other carrier? in addition, I have no Verizon sim and no AT&T sim as well I'm in Georgia and in our area, there are no such operators.
from my perspective it is good to have TMB firmware this would be the best option for me if it is possible
thank you in advance for your cooperation

If you install a different sim card it will basically switch to that carriers firmware

Not getting S8 software updates and getting errors (urgent) help plss

I bought my s8 today. I am on security patch of April. Whenever i tap on software update it says latest software already installed. My brother's s8 on the other hand is on October security patch. When i try to use Bixby voice it says update software to latest to use it. Pics below.

same boat
What kind of s8? Is it through a carrier? I have the same problem with AT&T branded. I called AT&T and after they tried to push the update to my phone after getting my IMEI and SIM info verified, nothing happened. They referred me to Samsung. Samsung said I could drive to a Best Buy an hour a way and they could load the latest software in the store. In other words, no one really is accepting responsibility for it. I am basically at the point now where I've decided to flash the updates myself.

I have identified the issue. My S8 is on UK firmware whereas my brother's is on Indian cuz he got dual sim. Is there any way to update to a global firmware or a firmware that gets updates everytime?

I'm by no means an expert, but as I understand it, all carrier branded updates go from Samsung to the carriers and from the carriers to your phone. Only unlocked comes from Samsung to you. (anyone feel free to correct me if I'm wrong).
If your carrier isn't pushing the update to you it could be because the carrier is not sending you the update because of the SIM issue if there's a mismatch in their system. There may be other reasons too, but that seems to be a common one.
Otherwise if you want to update firmware and it's not being sent to your phone, I believe the only alternative is doing it yourself. Check this forum for more advice.

That firmware AQDG is old, from like April this year. You can download a different firmware or an updated UK firmware from updato.com and update with Odin. Knox will not be tripped.

SM-T827R (US Cellular) flashed with T827V (Verizon Oreo) - Working no issues

I purchased a US Cellular branded Tab S3 to use on AT&T when I found out they sell them unlocked. I also recently wanted Oreo on it and after some digging found US Cellular still hasn't released an update but there was one from Turkey and one from VzW. I tried to find a concrete yes/no if I can flash other variants of the T827 models firmware without luck so figured I'd roll the dice on it myself. This weekend I tracked down the VzW Oreo firmware and used Odin to install it on my US Cell Tab. The first round I had a couple of errors and for a second thought I had a new paper weight, but kept calm and ran through the process again and it worked!
Just a note:
At first boot it will say the SIM is invalid and to put in a VzW SIM, but you can click ok and keep going. Once done setting up on wifi you can then go into settings and add the AT&T APN and connect over cell.
Could you post where you got the VZW image? I'd like to try this. I can't believe USC hasn't updated their tabs yet. I'm tired of asking when the update will arrive!

Not sure that was a good idea. If indeed you did manage to flash the VZW bootloader then the tablet is now likely bootloader locked with no way of returning to its original state.

Was this verified to be the case? Also would the verizon combination file work on the uscelluar tablet? I picked up a cheap SM-T827R4 that is FRP locked. I am waiting to hear back from the original owner if they would be willing to bypass the verification for me.

I was able to flash the combo file for the SM-T827V (Verizon version of the Tab S3) to bypass the FRP lock. I used the one on gsm-firmware.com After which I was able to reflash the uscelluar firmware from sammobile. I don't know if this is exactly the same as the OP's method, but hope it helps someone else out in the future.

Sorry for the late reply on this. I downloaded the image files from sammobile and installed them with odin. I've been up and running on Oreo (VzW branded) since my post and have had no issues or reasons to flash to anything else. I have tried to run an update but it says it can't register, which i assume is because it's hitting the VzW servers w an ATT SIM from a USC device!

You just need to put a Verizon SIM in it once (and so far only once) to check for updates. The SIM doesn’t even need to be provisioned. Then you can check for updates with your normal SIM.
I’ve had a VZW Tab S3 for over a year that I have been using with AT&T. I updated to Oreo without any issues with my AT&T SIM installed.
Wanted to first say thanks for the tip -- and echo that The T827R4 does in accept the Verizon Oreo firmware via the latest version of Odin, though with a build just a few releases behind it threw an error and would not flash.
I guess if we can't have root we may as well have Oreo.
Samemobile has the January security update Oreo

You're right about Verizon firmware running really smooth. Much better than the US Cellular firmware. After flashed VZ firmware, the model changed to SM-T827V.
in case anyone has the us cellular model, you really don't need to flash the verizon firmware because the us cellular model has a more updated firmware than the verizon model.
the model is actually SM-T827R4, oreo with apr 2019 security and OTA update works too.
though no pie update yet (same as verizon)
So these can't be flashed to the stock 820 pie rom?

Obtaining ATT Specific Functions On An Unlocked Phone

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
R38M205LY2B

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.

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.

Flashing unlocked U1 Firmware on Verizon SM-G975U

Hello! I've been out of the Android scene for a few years so I have a question that I can't seem to find the answer to by searches.
Can I flash the unlocked U1 firmware to a Verizon S10+ and use it on AT&T? I know I'll lose VoLTE and WiFi calling, but I don't really care about those. Mainly, I'm just trying to see if I can use a Verizon S10+ on AT&T. Ideally, I'd like to flash the AT&T firmware on the device but from what I've gathered, that firmware isn't available yet.
I had a Galaxy S8+ when it came out and I used Odin to flash between U1 and AT&T firmware so the process isn't entirely new to me.
A bit of background:
I'm looking to jump off of the dead iPhone train and hop back into Android with the S10+. I'm currently trying to sell/trade my iPhone XS Max in order to make the switch.
I have someone who is willing to trade me their Black S10+ for my iPhone as an even trade but their S10+ is from Verizon. It's unlocked but it's still running the stock Verizon firmware.
I just want to know what I have to do with this trade in order for it to work for me. I want to make sure I get a phone I can use. Any advice or input would be greatly appreciated!
Thanks for any help!
I'm not entirely sure if this will work on the S10+, I haven't tried it yet, but when I had the S8+(it was from Verizon as well), I'd take it internationally with a different sim card, it would just prompt me to reboot the phone and it would automatically apply the appropriate CSC settings. I was on stock VZW firmware as well and VoLTE worked (wifi calling didnt).
You should be fine either way though, people have successfully flashed the U1 firmware on their VZW devices for the S10+, so you shouldn't have any issues getting your AT&T sim card to work on it.

I wish Samsung included the BYOD update in the S10+, that would make it so much easier. I think I'm just gonna make the trade.
I've read through that thread and that's what I think I'm going to do. I'd much rather flash the AT&T version, but seeing as how it's not available, the U1 will do fine until it's released. I'll just need to switch to a different voicemail service in the meantime. lol
I got a Verizon S10+ and it is running build PPR1.180610.011.G975USQS2ASGB, I have confirmed that putting an AT&T SIM gives me network ability to call and what not. I want to flash the stock U1 branded firmware, is it okay if I flash G975U1UEU1ASD8 with Odin?

HEY I know have the same problem... Does it work.., I have installed the firmware and all so should I go for it.., waiting for your reply
I have Verizon unlocked phone and I'm able to use internationally where there is no Verizon, but I'm not getting updates so I have downloaded latest firmware should I flash it, also now I don't need any Verizon sim after flashing right ?
Yes you can flash U1 firmware to a U device and vica versa. The U means Universal, so you can flash AT&T, Verizon, T-mobile, or unlocked firmware to it. You gotta use the patched version of Odin though.

Can I flash the unlocked U1 firmware to a Verizon S10+ and use it on AT&T? I know I'll lose VoLTE and WiFi calling, but I don't really care about those. Mainly, I'm just trying to see if I can use a Verizon S10+ on AT&T. Ideally, I'd like to flash the AT&T firmware on the device but from what I've gathered, that firmware isn't available yet.
I had a Galaxy S8+ when it came out and I used Odin to flash between U1 and AT&T firmware so the process isn't entirely new to me.
A bit of background:
I'm looking to jump off of the dead iPhone train and hop back into Android with the S10+. I'm currently trying to sell/trade my iPhone XS Max in order to make the switch.
I have someone who is willing to trade me their Black S10+ for my iPhone as an even trade but their S10+ is from Verizon. It's unlocked but it's still running the stock Verizon firmware.
I just want to know what I have to do with this trade in order for it to work for me. I want to make sure I get a phone I can use. Any advice or input would be greatly appreciated!
Thanks for any help!

As Just changing csc without installing the system is more than enough. Even the company logo changes. Just look for the samkey program and you will see

NEW V35 [7/2020] Stuck on OREO?

Just bought this phone about a week ago, it is an Unlocked AT&T Model. It tells me basically that it does not need a OS Update - that it has the Latest 8.0. I am giving up on LG Support already!
Using their APK to update via USB told me that it cannot even check the Version of the OS, so definitely NO Update for this SUCKER!
Can anyone here PLEASE help me find a way to UPDATE this nice Smart Phone?
THANKS!

This is what LG's response is to me about getting my AT&T Unlocked V35 Updated fm A. 8.0:
Hi Michael, we appreciate your time in getting back to us. I will be happy to assist you today.
In response to your inquiry, for carrier unlocked phones, the only way to get it updated is, you need to have a service again with the original service provider for them to send or push the Software update to your phone. While LG has no control with the software updates for carrier unlock phones, compared to manufacture unlock phones it automatically receives the software updates that was released OTA (Over the Air).
I hope I have provided all the information and wish it has been helpful in addressing your query. It has been a pleasure to help you out to the best of my knowledge and my skills.
Should you have any other questions, please feel free and don't hesitate to contact us again via Email, Live Chat, or Phone by calling 1-800-793-8896. As this email is used for outgoing mail only, you may send file attachments, replies, any information and further inquiries over to the email section of support https://www.lg.com/us/support/email-appointment and we will do our best to assist you without you having to repeat the details of your previous message.
Thank you for choosing LG Electronics!
Sincerely,
Johannes
I have to leave T-Mobile [cheaper/better] and go to AT&T - RATS!

I heard from LG Support and they said that since it is an AT&T Unlocked Phone and not unlocked by them - I have to sign up with AT&T and noot my T-Mobile too get Updated....RATS....I just left
AT&T for better and cheaper service from T-Mobile and now I have to go back....guess I will and if/when they upgrade this NICE phone I will leave dem again!:laugh:
Or as I suggested, you simply cross flash to North American Open Market (NAO) firmware via Dev Patched LGUP.
You can also try temporarily putting in an AT&T SIM card (not even activated) and that can trigger AT&T update, if left for a few hours.
But people in other countries just cross flash to NAO as they don't need AT&T firmware whatsoever.

Yes, people report AT&T SIM card will do the trick. Either prepaid or postpaid, they are both the same. Supposedly they don't have to be activated -- as long as you have AT&T firmware on your phone.
Some say a Red Pocket (AT&T MVNO) SIM card will, also. While Cricket (owned by AT&T) SIM card will not.

Called Best Buy to see IF I could pay someone there to Flash my V35, like you recommend, but they are not allowed to do things like that. Turning to Craig's List now.
Hey buddy, it's easy to do yourself. Just follow this comment and the linked guide. Process is the same. Super simple and straightforward. Let me know if you have any questions.
https://www.reddit.com/r/LgV35/comments/f2yag4/just_got_one_should_i_modify_it/fhg34cy
Latest firmware for the V35 now (AT&T does have an early version of the Android 10 update, but kdz not released. We have to wait for a ULM kdz to be released to flash the 10 and update. Until then we're on Android 9 still) is the 04/2020 update. Sort by date on lg-firmwares.com, for device choose LMV350ULM, you want the ULM as its the unlocked carrier free version of the V35, and crossflashing the AT&T version is completely safe (I'm using an AT&T V35 in Canada on Koodo with the ULM software). In the software list choose GFI or USA (I'd recommend the USA version, unless you're on google fi).

Buy one of these AT&T SIM cards. Less than $3 with free shipping.
Leave it in overnight, see if the OTA update shows up.
Keep your T-Mobile. This is just to trigger the update.

THANKS for Great Suggestion, I looked over the LINKS etc. and bookmarked but at my age etc., I am alot more TECH SAVY than probably most 81 yr olds BUT I just don't feel confident enough trying to follow all of those instructions, wish I did....know it appears SIMPLE, but I just paid for this NICE Phone and would HATE to BRICK it!
BTW...just abit ago I got notice you sent me a PM but when I tried to open it [SORRY] I guess my Blocker blocked it and sent it into
CyberSpace or something....can't seem to find it now. I just followed ChazzMatt's TIP - and ordered a $2.99 ATT Sim Card to put into my LG V35 to hopefully trigger aN UPDATE. Laters, Michael
Just follow this video for upgrading your V35 to latest firmware
so, (directed toward Chazzmatt) I'm just needing a recommendation on which one to do (or wait for). Ive got the ATT unlocked model on MetrobyTMobile. (LM-V350AWM) I first updated it via modified LGUP to V350ULM20d (V350ULM20d_00_NAO_US_OP_0612), then to V350ULM20f (V350ULM20f_00_NAO_US_OP_0218). ((it still shows as V350AWM in the sys info, but all bloatware is gone))
Now, a while back I went into an ATT store and got them to sell me an un-activated sim card, and tried to update that way and failed (not knowing you had to wait a couple hours or overnight). My question is, would the simcard ota update work for me, and if so, would it be the full blown bloated att version of 10.
Or, should I just keep patiently waiting for the NAO KDZ (V350ULM30?) like you've been screaming for us to do since the very beginning! lol
(apologies for the gratuitous use of parentheses)
*Update - They're now saying we will be getting LG's new Velvet UI, should I wait even longer for that to be released???

The AT&T SIM card trick only works if you still have AT&T firmware installed.
If you cross flashed to another V35 firmware you need to wait for that KDZ to be released. It's coming. LG is just slow. Same deal last year with Pie.

ah, thanks for clearing that up! I'm guessing we might have to wait even longer now that they've announced we'll be getting Velvet UI and need time to add that to the KDZ, or is the UI update something that will come later on?
