Getting A Samsung S10+Unlocked have few Questions - Samsung Galaxy S10+ Guides, News, & Discussion

purchasing a New Unlocked Samsung s10 plus SM-G975U1 because i didnt want the bloatware & possibly may switch to different carrier down the road,my carrier is Verizon,just briefly read up on possibly losing some features.
- Wifi Calling
- Real Time Text
- VoLTE ("HD Voice") (Which means data now works while I'm on a phone call)
- Visual Voicemail
Can these all be reinstalled on a unlocked version?Phone comes with Pie 9.Or will i be ok and not lose these.Would updating to Android 10 fix this?

The Android version doesn't matter. As far as I know, you can't get them on the unlocked variant unless you flash a carrier firmware as all that you mentioned above is carrier related. Unless Samsung has put it in the U1 firmware, which I don't think they have.

Is migrating from G975U firmware to G975U1 safe?
Hello friends, how are you?
I have an S10 + / G975U that I got from my father who brought it to me from the USA, originally the device was from the sprint operator, but I paid and unlocked it, everything was removed from the operator and it now works with operators in Brazil, but now I am having an automatic update problem, "The current version of your software is not compatible. Visit a call center" reading this post I thought about migrating to the XAA firmware of the model G975U1, this process will end the problem of updates and had it been clean? can I lose my unlock with this?
I'm sorry if it's not clear, I'm using google translator.
Thanks.

[help] convert s9 G960U to global rom?

I want to covert my phone AT&T G960U to global rom? Help me
I actually don't believe you really can to be honest. The 960U is the US unlocked variant. So even if you wanted the vanilla feel you wouldn't get it. From my experience, each carrier has been using the same variant of the S9 so they would just rebrand it with a OTA update.
Personally I've switched from Cricket (Original Purchase) to Boost (Boost ROM loaded) to Straight Talk (Verizon) with no issues except one. Which has to do with Sprints activation crap. The latest carrier switch has a default boot screen from Samsung.
You may be able to flash a rom using odin that isn't carrier branded. Like I said though, I'm pretty sure if its activated an OTA update fixes you up either way.
I get my firmwares from Sam Mobile.

Carrier firmware

I currently have the US s20Ultra unlocked model on ATT (don't foresee changing carriers). Currently I am missing features like VoLTE and VVM. What other features would I be missing if I stay on the unlocked firmware? Can I flash the ATT firmware to get those missing features? Can I flash back to unlock?
Thank you
What's the CSC on your device?

I am not sure what I am looking for. Its currently on ATT/ATT.
Open your dialer, enter *#1234#, press the Dial Icon. You'll see CSC: G98??, the next 3 letters will be your device's CSC Code. Your Service Provider's CSC is "ATT" which is different than the CSC in your device. Whether or not you can change the CSC depends on your device's CSC. Device firmware is always configured for the specific, original CSC or Multi CSC's.
This post may be the best workaround.

Your device has Multiple CSC's which are included in OYM so you should be able to change your CSC to ATT, which is the CSC for AT&T.
Go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press the Dial Icon, you should see a screen with the list of available CSC codes for your device. Select ATT and tap the Install option.
Be aware your firmware isn't AT&T, it's unbranded so even if you change the CSC, full call functionality may not be available. You can obtain AT&T's firmware at SamMobile.

Varcor, thank you so much for all the directions.
As it stands right now, it is already on ATT. Once I flash over to the ATT firmware, would I be able to flash back to an unbranded one in the future, for whatever reason? Additionally, do I have to stay on the ATT firmware to retain those features? Or could just having my phone communicate with ATT at least once with my "branded" phone and then flash back retain those features?

You're most welcome. Yes, flashing back to unbranded won't be a problem. I don't think you will be able to retain the features if you go back to the unbranded firmware, it's not configured to allow full call feature functionality. Also, after flashing to the AT&T firmware you may need to contact their CSR for external programing. Good luck!
S20+ AT&T
Hi Varcor,
I'm new in this firmware things. I'm from Singapore and has been using S20 Exynos, but due to the extreme heat, bad battery life,etc. I've decided to import S20+ Snapdragon from AT&T, according to the Service provider SW ver information, it's showing as SAOMC_SM-G986U-OYN_ATT_QQ_0023 (I believe this means the set are unlocked).
With that said, I noticed that the software is outdated and the security patch level is on February 1,2020. when I referring to the AT&T website, It's showing as the latest software is QP1A.190711.020.G986USQU1ATE6 (June update) and mine still on QP1A.190711.020..G986USQU1ATAW (February). My CSC is G986UOYN1ATAW.
My question now is, whenever I tried to hit the software update, it's keep telling me that my software is up to date. Is there's a reason why it's wont detect the update? If it's because I'm in Singapore not US, then there's no choice that I need to flash using the firmware from Sammobile. The problem is which one that I need to download as AT&T carrier is not listed there. There's only T-mobile, Sprint, Unknown, USA. Please help.

I would reach out to SamMobile and inquire why they're not listing the AT&T Firmware Update. You state your CSC is G986UOYN1ATAW. That CSC is also associated with T-Mobile. You're not using an AT&T SIM Card, correct? On a Multi-CSC Device when you insert a different SIM, the device should update to the correct Service Provider. If you're using a SIM from a Service Provider other than AT&T you probably won't receive AT&T Software Updates, which are distributed by Samsung, not AT&T via OTA.

I did try to reach them, but for some reason they are giving me some irrelevant answer. Something like "You probably don't get OTA-updates (otherwise you got them already from AT&T)". We are having a conversation breakdown there, I think they are not an english speaker (or my english is just bad). Really? that CSC is associated with T-Mobile? now I'm getting more confused because the box is stated AT&T and it's sealed.
I'm using Singapore SIM card (Singtel), so you were saying this set I'm using right now is a Multi-CSC device? If i were to flash to the other carrier firmware, will it create any problem?

Flashing Singtel Firmware won't work since it's configured for the Exynos SoC. Multi-SIM Devices have only regional Service Providers available, you don't have Singtel as an option in an AT&T device. Based on your situation I would consider one of two options. The first would be insert an AT&T SIM just for OTA updates. Not sure if you received an AT&T SIM when you purchased the device, if you didn't they're not hard to find. The second and likely best option is sell the device and purchase a Global Variant with a Snapdragon SoC, you'll receive updates regardless of your Service Provider. If it makes you feel any better there's lots of users in the same predicament. They want the Snapdragon device in regions selling mainly Exynos devices. Workarounds are in many situations are challenging,

I have the exact same phone and using the same network as garyHal, unlocked 988U1/OYM/ATT.
I got my bootloader unlocked and decided to apply the ATT firmware (
G988U1UES1BTJ2). My CSC was already ATT so I didn't perform the csc install step.
After setting the phone up as new, it still seems like its running the unlocked mode. I don't see any kind of branding or extra ATT stuff that may have been downloaded. How do I verify that I have the right firmware and CSC set to ATT?
Thank you.

How did you manage to unlock your bootloader since US Snapdragon variants are locked down pretty tight? I don't think the firmware is dedicated to ATT, it's Multi CSC, designed to function with a number of US Carriers. You should be delighted you're not suffering with ATT bloatware! To check the Active CSC go to About Phone, Settings, Software Information, Service Provider SW ver. On the bottom string the first three letters are the Active CSC on your device. You can review this article for additional information on Firmware and CSC's.

If I am reading it correctly, this is what I am seeing:
ATT/ATT/XAA
I am happy that I don't have the ATT bloatware but I also feel that ATT is locking me out of some of their features because I don't have a "branded" phone, such as wifi call or visual voicemail. Am I misunderstanding your post from above, #6, that flashing ATT firmware would give me the carrier features?
Additionally, does the firmware determine what frequency bands I am using and if I am taking full advantage of ATT's offerings?

Flashing ATT Dedicated Firmware would give you the best chance for additional call features ASSUMING your Ulocked Device is capable of incorporating those features. It should do the trick since the hardware is identical to an ATT device. I would head to an ATT Store to get a definitive answer. Samsung has made it more and more challenging to mix and match branded and unlocked devices with CSC or Firmware modifications. In many cases you won't know until you try. Users want their smartphones to be smart, to work perfectly in every situation but the major carriers use proprietary tools to hold clients hostage.

Every carrier? What? I know of 3 versions of a11 for the G8; 1) the korean Open 2) The Verizon version 3) The Canadian Open.
Hardly 'every carrier'. Updates are coming, slowly, and there is no guarantee any one individual carrier will update their software. That's an LG issue really, they have contracts with carriers with various stipulations that can affect say US Open version, which supposedly can't be updated unless all the other carriers update theirs first. It's complicated.
Call t-mobile, they can tell you when / if an update will be available. And of course, there's always the issue of what you've done to your phone. If you do something like unlock the bootloader, you won't get an update even if there is one.
cheers

ATT has also released A11 ? I've seen in some forums that it has.
For what it's worth on reddit T-Mobile users are saying they're getting the update. I can't speak for myself because I'm using a custom rom but yeah...it's out there

Actually, that's not the US Open variant, that's the CCA variant. I'm not sure what the difference is, maybe someone can elaborate.
The lg firmware site has it listed as the US Open, but download and compare the hash tags, they don't match. But if you download the CCA version the hash will match.
I've actually never heard of CCA before, it's Competitive Carriers Association, I've heard of BrightPoint, etc, but not cca. Until someone tries it, we're not sure which carriers it's compatible with re volte and vowifi type stuff.

My phone is originally BrightPoint. I flashed the US OPEN listed on the lg firmware site, hoping that it wouldn't throw up an NT ID error, but it does :-(
Additionally VoWiFi worked with the Canadian Open but it's not working with this rom. The default email app is also missing in the US version.
The software version shows as V30c-USA-XX, with a security patch of Dec '21.

Interesting that it's not working vowifi and nt error code, that should absolutely not be the case if it was the USA version, no way. At least not if you're here in the states.
Where are u using it? Canada? That might be at least part of the reason, have you ever used the a10 US Open there? How did that work?

Sorry for not clarifying earlier, I'm using the phone in India
To get volte and vowifi to work, I change the target region & country to ESA and operator to OPEN in cust.prop. And i also edit the carrier_code, telephony and vo_config files to contain details of the networks in India.
VoLTE has worked with many A10 roms, but VoWiFi worked for the first time with the A11 Canadian Open.
PS - Since I need an unrooted phone for Microsoft apps such as Outlook and Teams, I uninstall magisk after making these configuration changes.

Tmobile S20+ with VZW Android 12 ROM??

I'm sure it's been asked already but I can't find any threads on it.
Seems like every carrier is getting Android 12 on the S20 line EXCEPT T-mobile.
I have an s20+ that is still under contract and carrier locked.
Is there any way to use the VZW firmware on it? Co-worker has same phone on VZW and has same FW version base (G986USQS2).
His full version is G986USQS2EVA4 which is android 12. My current firmware is G986USQS2DUJ7 which is obviously android 11.
Can I download and flash the files from VZW from samfw.com? Would I need to change CSC?
Or could I just pop in a VZW Sim (even though it's locked to TMO) and it would just download the FW?
Thanks for any help.. It's REALLY frustrating that even Xfinity and comcast are getting it already but not Tmobile............
There is a REASON I bought a flagship from a major carrier.. Updates... But seems like tmobile is in last place to get it figured out.

LMG820UM3 on US Mobile (Verizon) - Need Help

Hello,
I will try to keep this short and sweet.
I am on US Mobile using the black sim (verizon towers) and currently have a LG v30 that no longer can make calls due to Verizon shutting down cdma beginning of 2023.
I have my brothers Lg G8 ThinQ phone purchased from US Cellular. It is now rooted and I followed this guide to add LTE support for other carriers:
[GUIDE] [NO ROOT REQUIRED] [EPIC UPDATE] How to add VoLTE support for other carriers to the G8 (and other Qualcomm powered LG devices too!)
This guide will not work if you are running Android 12 :( I'm gonna keep the intro simple, been a longtime user here on XDA, and recently I found that my T-Mobile LG G8 only supported VoLTE and VoWifi on, you guessed it, T-Mobile! So I did some...
forum.xda-developers.com
I used the mbn files provided from the guide and loaded a few of the US carriers. Upon putting in the sim, and trying to change settings to get it to work, I can only get data to work but texting/calling (in/our) does not work at all. When attempting to make a call, the 4G indicator also disapears. I contacted US Mobile thinking it maybe was a APN issue but they stated on their end that the phone is incompatible.
Not sure what else to try. My only hunch is maybe reloading mbn files from a downloaded KDZ but I have no clue if that will work (also to download 5 gigabytes takes a few days for me).
Any help is greatly appreciated.
attached is both the phone info and a snapshot of PDC of it showing VZN got activated on the phone with the sim in it.
EDIT:
For if anyone else comes across this. My solution was to crossflash (using the guide in the LG G8 fourms) the open market KDZ and I went with G820QM30c_00_NAO_US_OP_0103.kdz as I had android 11 already installed and that it was the A11 version download the most from here: https://lg-firmwares.com/lg-lmg820qm-firmwares/
I did have to correct my FTM partition but that crossflashing guide links to some good solutions.
*Note: Only issues that I have seen with the version i flashed is i cant add an APN. The button is just missing so had to install an app to view it, and when receiving gifs, they turn into pictures only. both things I can live without as not volte works on verizon (us mobile).
So, which rom would normally work with that carrier? I'd guess the us open version would work, why not just flash that on the G8? I've no idea what bands us cellular rom supports, but I'd trust the correct rom (for the current carrier) to work rather than following that thread to 'add bands'.
I used that thread once, didn't accomplish what I wanted. Not to say it doesn't work, I didn't try that long. But have flashed numerous roms re diff carriers, that always does what it should re correct bands.
Frankly, I am not sure if my reply will be helpful, and I know nothing about the US Mobile specifically, but just wanted to comment as an owner of a G8 originally from the US Cellular. Feel free to ignore this if it seems irrelevant...
I bought my phone second-hand with an original US Cellular A11 stock ROM. Later cross-flashed it to the Canadian Open when A12 became available. Rooted with Magisk. I am using the phone on the Rogers network in Canada. On both ROMs I have no issues with data, voice and text - everything works, including concurrent voice calls and data usage.
A (possibly) dumb question - have you tried the original US Cellular ROM as is, before diving into the guide to add LTE support for other carriers? Is there a chance that it would just work?
Regarding the previous reply, I couldn't find a US Open ROM available for the 820UM models (only for QM), but you could try Canadian Open, for example. My point is to try and make it work with one of the ROMs as is, without messing with some extra steps that may or may not work.

Yeah, I guess i understood that as being able to add the functionality. But after more research, flashing a different rom is more likely to be the solution, which confuses me about adding profiles if it doesn't truly work?

So yeah, after more research, looks like flashing either the open market or the verizon specific variant would work. I did try it first without any modifications to the us cellular rom but still not everything worked. I have a Lg v30, but few things that are no longer ideal was the recent CDMA discontinuation from verizon at the start of this year, also had recently dropped it and the screen flashes bright white light in your eyes at random times... so lol, not ideal.
What Im probably going to be trying when I get the time is flashing the open market, and if that dosent work, it seems the verizon specific would.
Thanks both for the inputs!
