Hello! i flashed with full wipe the SM-S908U DSH unknown firmware over my ATT branded S22 Ultra, thinking that it was the unbranded version. I still have all the ATT branding everywhere and also the ATT software update option in settings.
My question is: will i still be able to get OTA updates with this firmware?
Unbranded firmware is U1 firmware. DSH is Dish network/Boost Mobile

The weird thing is that even though I flash dtbe full firmware, when I booted up, I still had the ATT customizations, but in settings it shows the firmware is updated to the DSH that I flashed? Very weird.
The reason is that DSH firmware is still U firmware with a CSC that adapts the firmware to the SIM installed, therefore it reverted back to AT&T. As previously stated, you need U1 firmware, unlocked defaults to XAA in the US.
So what will happen if I dirty flash with the Home CSC the new DSH U over my SM-S908U1 that has been already flashed from U1 to carrier U Xfinity Mobile hard sim and a T-Mobile eSim ?
Will I still keep my same Xfinity Mobile T-Mobile carrier data ?

I have a smg930v convertet into smg930f due sim support how can i update it to nougat to support all sims
930V and 930F are completely different chipsets, you can't just convert from one to another. What model does it say it is in download mode?
If it's a 930V then you can try flashing the 930U Nougat firmware from sammobile or updato, as it's the unlocked firmware. But if the phone is carrier locked to a SIM, you will need to get it carrier unlocked which can't be done with a firmware flash.
If it's a 930F you can flash the default UK firmware it ships with if you buy it carrier unlocked, also from sammobile or updato
I have a samsung s7, I had some problems with it so I had to reinstall it via Odin. I downloaded a firmware called SM-G930f Three sweden. and since then the phone was locked to three sweden. is it even possible?? How and why? I downloaded other software but the problem persists. Is there even a solution? I could use any sim card before i installed the Wrong firmware
I don't think it's possible for carriers to retroactively lock and unlocked device, each country and carrier has their own firmware which can affect your network compatibility if you're using the wrong one.
Try finding a non-carrier specific firmware from updato.com or sammobile.com and flashing that, you can also try flashing the UK BTU firmware since it's the stock unbranded firmware.
Start with just flashing home_csc and nothing else if you don't want to lose any data, but if you want to do a full flash them all 4 files using normal CSC.
Sorry in advance if I missed the answer somewhere on here already...but I see a lot of posts about flashing carrier versions and switching carrier versions.
My question is, if I have the UNLOCKED US version (SM-N986U1) on my T-Mobile account, is there any benefit to using the TMB firmware vs. the XAA firmware...or is there any benefit to using he XAA instead of the TMB?
It came with XAA and I switched to TMB prior to joining the One UI 3.0 Beta. At some point I was having text message issues using Google Messages, but I can't remember which variant I was on when that happened. So, I basically want to use the firmware that will give me the best experience without a bunch of carrier crap.
Thanks in advance for the help!
I'm not sure what you mean by "came with XAA and I switched to TMB". Isn't the N986U1 XAA firmware identical to the N986U1 TMB firmware? But the N986U firmware is different from the N986U1 firmware, and differs for each carrier. You can flash either the N986U or the N986U1 firmware on your N986U1 phone.
Not sure...I may just not know what I'm talking about...lol. Under Software information and Service Provider Software Version, it ended with XAA/XAA/XAA when I first got it, but then I flashed the T-Mobile firmware and it has been TMB/TMB/XAA ever since.

Well, you should have access to early updates as carriers usually get updates before unlocked versions and since ur already on Tmobile, you might get additional apps that work with Tmobile?
Go with the Unlocked (XAA). I converted my Verizon model to the Unlocked firmware and there are a lot fewer preloaded apps and other junk. T-Mobile services are apparently fully functional on the Unlocked model as well.

Thank you!! I also got the US unlocked XAA and converted to TMB firmware... I have flashed multiple times XAA to TMB and TMB to XAA.. For unknown reason when I use speedtest, I see faster download speeds on the TMB variant... For example, with TMB I was getting 120 mb while on XAA I was getting 76.. I did this couple of time in a span of a week.. it was coming with similar differences..
Like you, I've been using TMB on my US unlocked as well.

if you just want to move from XAA/XAA/XAA to TMB/TMB/XAA, you don't need to flash firmware, u can change CSC from XAA to TMB to achieve the same results.
Flashing firmware from XAA to TMB means u are moving from firmware of SM-N986U1 to firmware of SM-N986U (carrier branded).
Hello, I have an unlocked Galaxy Note 20 Ultra from Verizon. I am wondering if it is possible to fully convert this device to work fully with TMobile I was specifically wondering if it's possible to use TMobiles 5G Network on this device. I have flashed the U1 Firmware to the device but it never showed me an Option to choose my carrier or anything like that, and even though the Signal shows 5G whenever I turn a speed test or view the cell info it pops up as LTE
You need to change your device CSC to TMB and flash TMB U firmware, not U1.
You device currently shows VZW/VZW/VZW in your screenshot.
It should read TMB/TMB/TMB, or at least VZW/VZW/TMB.
The SIM card itself will determine what network you have access to.
Be careful though as you have now flashed newer firmware with the new version 2 bootloader.
So you can only use firmware with that bootloader version. No going back.

If you change ur CSC from VZW to TMB, then it will read TMB/TMB/VZW in your screenshot.
You can only change to TMB/TMB/TMB if you root your phone .

Please note, some codes in original post don't work for some, with latest 10.1 Update.
Using Sammobile, I've seen U1 firmware with a T-Mobile CSC. That way you won't have all the T-Mobile apps or boot screen.
Hello, which firmware has Samsung Smart call enabled. I have N986U1 and it is disabled. I don't want to try every firmware to know does it work or not? Please USA only.

U1 (XAA) device has it. This is my 986U ATT converted to a U1 XAA device.
So looks like it doesn't work with non-USA or different SIM card.

Unfortunately it's the CSC code that determines what features are available.
I did a CSC change on mine back when dialer code/IMEI still worked.
My phone was a stock 986U ATT device. I changed CSC to XAA and loaded U1 firmware.
My phone didn't retain the XAA CSC, after a 3rd reboot, but all the stock features remained.
Call and text on other devices works (normally blocked by AT&T), and Smart Call works as well.
Still can't get eSIM working, but that is only available for T-Mobile CSC.

I have converted from ATT to XAA. About phone it shows XAA/XAA/ATT and updates comes XAA. Or I haven't changed CSC?

It's changed... All AT&T U devices will retain ATT in the 3rd set (???/???/ATT) as that is the original sales code for the device.
Having XAA/XAA/ATT with U1 firmware should let you have access to some XAA features.
