For anyone who's feeling brave, bootloader 3 has been released for the U1 model, available via SamFirm and Frija (build ending in TA3). Be aware that at this time, there's nothing else that you can flash if there are any bugs etc

I have to flash unlocked firmware in T-mobile S10 - in firmware zip file there are 2 csc files "CSC_OMC_OYM_G973U1.." and "HOME_CSC_OMC_OYM_G973U1.." -which one I should select for CSC in ODIN ?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
The first one
[Samsung Galaxy S10 Guides, News, & Discussion] cristirms:
to what help, will the problem be solved on the phones sold by verizon only go for a few minutes with another sim?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
I can't understand what you're saying
[Samsung Galaxy S10 Guides, News, & Discussion] cristirms:
Yes.My SM-G973U is selled and branded Verizon. I use this phone in Europe,work perfectly with another sim for 3-4 min,after what,no signal.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
So the signal simply goes away? You don't get any sort of error message or notification?
[Samsung Galaxy S10 Guides, News, & Discussion] cristirms:
it is normal g973 u. after a few minutes i received a message from verizon that the phone is activated on another network.

now I have written in g973 u1.software now after going a few minutes to ask for NCK code
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
That message means that the phone was never network/SIM unlocked from Verizon. I can give you a recommendation for a 3rd party professional unlocking solution if needed
[Samsung Galaxy S10 Guides, News, & Discussion] ljk1984:
Man, sorry for the dumb questions, but I've never messed with this stuff before...feeling a little overwhelmed.

I bought an unlocked S10 to use on Verizon. (I think it may have been a Sprint phone before...Service provider SW shows VZN/VZN/SPR). It currently has Android 10.

I found out I currently cannot get Visual Voicemail with Verizon right now. Can I flash the Verizon firmware to get all the Verizon options like visual voicemail?

Is there an Android 10 firmware and VZW userdata for download? Thanks.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If they don't have an app in the Play Store for it (like some carriers do), then yes, you can convert it to full Verizon firmware. It should have done that already when you inserted the Verizon SIM though. Do you not have all the Verizon bloatware like a regular Verizon S10?
[Samsung Galaxy S10 Guides, News, & Discussion] ljk1984:
Thanks for the reply. Unfortunately, Verizon is one of the carriers that does not have a Visual Voicemail app in the Play Store. When I put in my Verizon sim, it did download some Verizon apps (call filter, cloud, my verizon, etc.)...but nothing for Visual VM.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Does it now show the Verizon logo at startup?
[Samsung Galaxy S10 Guides, News, & Discussion] ljk1984:
Yes, it does show the Verizon logo. I guess I do have a Verizon VM app, but all it does is tell me I have X # of messages waiting and gives me the option to call my VM (*86). If I had VVM, I believe I would access it thought this same app. I thought maybe I just needed VVM enabled on my account, but Verizon told me their system wouldn't allow them to add it to my device.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
That's what I was afraid of. It's likely a restriction on the IMEI and/or serial number because they know that it's not originally one of their own models
[Samsung Galaxy S10 Guides, News, & Discussion] ljk1984:
So if I understand correctly, I need to flash the U1 firmware, SAU - 1 - 9.0, then flash the U firmware with VZW userdata. Do I want the firmware and userdata files from the SF6 - 2 folder? Will this put me back to Android Pie? Then I would just update to Android 10 after the phone is flashed?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
1. I would really recommend finding several "beginner's guide to Odin flashing"-type posts here on XDA and reading them. Being able to identify the bootloader version of a given build and knowing what versions you can flash based on what version the phone currently has is going to be essential knowledge. You can't flash SAU if your device currently has bootloader 2.

2. The above is kind of moot anyways, because I'm assuming that even if you do the conversion to U1 and back to U with full Verizon bloat, the phone is going to end up looking the exact same way that it does now, and I'm also assuming that the same problem will still exist. That's why I commented that it's likely an IMEI/serial number issue, instead of a firmware issue
[Samsung Galaxy S10 Guides, News, & Discussion] ljk1984:
Thanks for the advice. Maybe I'll just try finding a Verizon S10 to trade.
[Samsung Galaxy S10 Guides, News, & Discussion] prince_72:
I am looking for the latest (Feb) AT&T userdata? Have you seen it somewhere
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Are you referring to TA2? That's the latest as of right now, according to AT&T's website
[Samsung Galaxy S10 Guides, News, & Discussion] prince_72:
Yes the TA2. The ATT userdata that I could find is the SKP. Since I am not getting the updates automatically I flash my phone. Also OTA would be ok if I can find the OTA from SKP to TA2 (2/3 incremental updates).
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If you're just looking to update, then you don't need the USERDATA file. What you really need is just the 4 base Odin files. USERDATA doesn't need to be flashed if you're sticking with the same firmware but just updating
[Samsung Galaxy S10 Guides, News, & Discussion] prince_72:
I guess I can use the 4 files as you said plus the HOME_CSC (I want to keep my settings/file). The latest userdata I have is the USERDATA_ATT_G973USQU2CSKP. Since this has a bootloader 2 then I can be using it in all version (if I want to flash from factory reset) as long as the bootloader version is 2. Is this right?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
I wouldn't recommend using it with any Android 9 versions. As long as you're flashing Android 10, then it should be okay to use
[Samsung Galaxy S10 Guides, News, & Discussion] prince_72:
I have a Canadian model (973W) and I have flashed with with ATT firmware (U model) including the userdata just because I want to have the wifi calling. My IMEI probably is not at ATT servers so I can get the updates so I would have to do it manually. Now if I update the firmware and I flash the 4 files plus the home_csc in theory I should not loose the wifi calling?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If you mean the 3 files (AP, BL, CP) plus HOME CSC, then yes, in theory. But if wifi calling works right now, modifying anything might make it stop working
[Samsung Galaxy S10 Guides, News, & Discussion] prince_72:
It took me quite some time to understand how wifi calling works. At the end I added another IMEI (from an ATT phone) from my account where it says add new device imei and sim card number and only then it worked. It seems that imei is related to the ims server for customization. I know if I call ATT, the agent has a generic IMEI to add it (instead of me) which will allow the wifi calling registration.

I might wait a bit until I find an android 10 userdata.

Do we know what does the userdata contains? It is customization for ATT but what exactly. It is almost 1Gb file
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
1. You already have an Android 10 USERDATA - SKP is Android 10,

2. USERDATA is all of the carrier bloatware - apps, logos, etc
[Samsung Galaxy S10 Guides, News, & Discussion] prince_72:
Can I flash the userdata (Android 10) on top of any other android 10 version or I need everything the specific version of userdata?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
There's no need to flash USERDATA unless you're coming from U1 firmware
[Samsung Galaxy S10 Guides, News, & Discussion] xdanilva:
I examined the userdata file and I found that it only contains a script of what to delete and references to every carrier bloatware. All the bloatware is located on a separate partition
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Then how do you explain that all USERDATAs are almost a gig in size...?
[Samsung Galaxy S10 Guides, News, & Discussion] xdanilva:
Oh I forgot to add that theres two zip files containing optional Samsung apps for dex and for Samsung. All the rest of the files are dex and vdex files mostly.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
That doesn't make any sense. U1 firmware also has the same Dex capability, yet does not have a USERDATA file
[Samsung Galaxy S10 Guides, News, & Discussion] xdanilva:
Well for the U userdata I mean
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Still doesn't make any sense.

If the only purpose of the USERDATA file is for Dex capabilities, then how can the U1 firmware have all of the same Dex capabilities as U firmware, when the U1 firmware has no USERDATA file?
[Samsung Galaxy S10 Guides, News, & Discussion] xdanilva:
Oh oops dex in this case means those .odex or .vdex files you see in app folders. There are two zip files one for the apps themselves and one for the .odex and .vdex cache files. It's weird how they're seperated
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Ohhhhh. You said "apps for dex" so I thought you meant Samsung Dex
[Samsung Galaxy S10 Guides, News, & Discussion] xdanilva:
I thought that's what it was at first lol
[Samsung Galaxy S10 Guides, News, & Discussion] yonith:
I just purchased an SM-G9730 that boots with the TMobile spash screen. I flashed everything for the ATT version since I'm on ATT but the TMobile splash screen remains on startup/shutdown. What am I missing here?

UPDATE: USERDATA_ATT_G973USQU2ASF6_CL16154136_QB24242882_REV00_user_low_ship_MULTI_CERT.tar.zip and G973U_SF6_2.zip
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You're missing the steps given in the OP
[Samsung Galaxy S10 Guides, News, & Discussion] yonith:
Missed the part about installing U1 first. My phone was already on the newer BL, so I downloaded and flashed the U1 (G973U1UEU2CSKP_G973U1OYM2CSKP_ATT) from SamMobile. I thought it was weird that the file had ATT attached to it being it's the unlocked U1 version...

Anyway, since the ATT firmware download for the U version of SKP are not on SamMobile, what are my options? I'm thinking it's either stay on U1 or just flash TMO U?

UPDATE: Scratch that! Read some more and it looks like I just need to download any U version of SKP and then I can just use the ATT USERDATA file from the OP. I just wanted to be sure I didn’t miss out on any features like HD Calling or Visual Voicemail. :)
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Correct. I usually won't post a full build if other carriers get it in addition to AT&T, since those builds are freely available anywhere
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
AT&T and Cricket USERDATAs for bootloader 3 (build TB3) have been added to the OP, as well as the rest of the Odin files for that build, because it appears that only AT&T will be getting that specific version
[Samsung Galaxy S10 Guides, News, & Discussion] :
I haven't logged into this site in almost four years. I had to dust off my account just to thank you for this. Thanks.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
All USERDATAs are in the same folder as the firmware
[Samsung Galaxy S10 Guides, News, & Discussion] djrecon:
Oh, Ok. Great!

And i saw you originally wrote that the U models are the carrier models and the U1 is the Samsung Version.

So if I have a U1 device, but want the ATT firmware, should I download the U or U1 firmware package?

I downloaded the U1 but didn't see anything that said AT&T in the folder. Are all the carrier firmwares in the same file and I'll be able to choose which one i want within Odin?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You've answered your own question. If the U model is the carrier model, and if you want carrier firmware, then you need to flash U firmware
[Samsung Galaxy S10 Guides, News, & Discussion] djrecon:
Ok great. Thanks.

So then if I want AT&T, I should download G973U_SAT_1.zip & USERDATA_ATT_G973USQU1ASAT_CL15296297_QB21819657_REV00_user_low_ship_MULTI_CERT.zip, correct?

Do I need anything from the SBA Folder?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If you want SBA, download SBA files. If you want SAT, download SAT files
[Samsung Galaxy S10 Guides, News, & Discussion] djrecon:
I'm sorry. This is new to me and I don't know what the difference is between SBA or SAT. If I just want a stock ATT Phone, which files should I download?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Either one. They're just two different versions. You'd need to look up Samsung's changelogs if you want to know the specific differences
[Samsung Galaxy S10 Guides, News, & Discussion] djrecon:
And then when I'm in Odin, do I flash both the AP and USERDATA at the same time, or should I flash AP first, then flash USERDATA second?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
All files at the same time
[Samsung Galaxy S10 Guides, News, & Discussion] djrecon:
And just double checking that there is only an AP file in that firmware download, right. That's all I need (along with USERDATA)?

I don't need the BL, CP or CSC files to flash?

---------- Post added at 11:04 PM ---------- Previous post was at 10:54 PM ----------

I'm confused because in your original post it says "The large files will be your 4 part firmware".

I only see one part in the extracted firmware, the AP. Is that right or am I missing files?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Yes you need all 4 files (5 once you count USERDATA). I have no idea how you only got 1 file out of the firmware zip - there are 5 files in each zip. I would recommend consulting some "beginner's flashing tips" threads and doing quite a bit of reading and research before proceeding, if this is your very first time ever using Odin
[Samsung Galaxy S10 Guides, News, & Discussion] djrecon:
Ah. Got it now. tried extracting again and they all came through.

Flashed the phone with the SAT version and it's up and running the ATT firmware, Thanks! But, the Wifi calling option is still missing from the new settings menu. I'd like to try the SBA version, but there's no AT&T USERDATA in the SBA folder. Does that mean I can't use the SBA with AT&T?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Hmm not sure how I missed ATT and Cricket for SBA, but I'll upload those now.

But, USERDATA isn't required if you're sticking with the same carrier firmware and just updating. You can just flash the other 4 and be perfectly fine
[Samsung Galaxy S10 Guides, News, & Discussion] djrecon:
I think that's it! Seems like everything is there! Thank you so much!

Can I donate to you at all for your time? I really appreciate it.
[Samsung Galaxy S10 Guides, News, & Discussion] spidey44:
Quick question - I'm on the U1 firmware on TMO and trying to figure out if I should move to the U version for better signal and speed. In reading I am seeing mixed options on this. I know that U will add carrier bloat but does it also provide optimization for signal and speed (ie Carrier Aggregation) ? Any insights would be appreciated.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Just clicking the Thanks button on a few posts is good enough :)

Each carrier's firmware is configured for optimal performance on their network, using their bands and frequencies. So in theory, performance would be better. But the only way to know for sure is to try it

S10 Unlocked no signal/only emergency calls

Hello guys, anyone can help me?

I bought a s10 factory unlocked to use in brazil, the first 2 days it was all fine, and then i can't get signal, or when is registered in network, doesnt make or receive calls and the internet doesnt work.

I already reseted the cellphone, tried another sim card, flash the firmware too, and nothing works. I downloaded a program called network mode to change the type of signal i wanted, and it get registered in network but no calls.

Tried set the network manually in the config, but no results. Samsung and carrier support didn't help either.

What can i do in this case? ( I already wipe the cache)

Is it true that i cannot use the ZTO firmware from the sm-g973f?

I am worried, because if nothing works, the s10 will become a brick haha.:crying:

Maybe it's because this model have the snapdragon and the brazil have the qualcomm?

My Model is the sm-g973U1 128gb.

Looking forward for an answer, tks

What would the manual entries be for U1, and VZW?

it's not blacklisted :/
[Samsung Galaxy S10 Guides, News, & Discussion] Chris!:
If anyone could help please do. I bought a unlocked s10 which means it had U1......i decided to use Odin and go to U with Tmobile. (i get video chat, read receipts, typing indications, etc) So everything went smooth. I download the 4 files, downloaded the tmobile userdata as well and the phone was running good. But now i can not connect to the network. It seems like i'm running on 2G Network or something. The phone usually says i am not on a mobile network and then as time passes by it says im on the 4glte network at the top and then it goes away again and says im not on a mobile network. I was trying to go back to U1 but couldnt figure out how to do that either. i was using 3.v3.13 and got the SHA256 error so i downloaded another verision of Odin (Odin Prince Comsy) and but then i got a different error. any ideas?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
I appreciate that!
[Samsung Galaxy S10 Guides, News, & Discussion] toby12188:
So, i have an AT&T-locked S10 running G973USQS2BSIW. I can use odin to flash the files in G973U_TB3_3.zip along with the TB3 ATT USERDATA and that will still be 100% stock ATT firmware that is fully functional?
[Samsung Galaxy S10 Guides, News, & Discussion] Replicatorz:
Wish there was step by step instructions on how to apply this.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Yep.

Odin flashing is really pretty easy.

1. Download firmware zip and extract

2. Boot phone into Download

3. Load files into Odin

4. Plug in phone and click Start

There are plenty of detailed step-by-step guides out there, if you need more than that
[Samsung Galaxy S10 Guides, News, & Discussion] Replicatorz:
Is there a benefit of this over using something like this?

https://samfrew.com/download/Galaxy__S10__/cuy8/CCT/G973USQU3DTD1/G973UOYN3DTD1/

^I would rather not download this one, size is bigger and takes forever.
[Samsung Galaxy S10 Guides, News, & Discussion] toby12188:
Thank you, I did the flash with Home CSC and everything worked great. I've even received a couple OTA's since flashing.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
I don't know anything about that website. You download and flash at your own risk
[Samsung Galaxy S10 Guides, News, & Discussion] Replicatorz:
I will probably use yours as atleast i can download it in a reasonable amount of time, just the one i linked is newer and bigger size and just wanted to know if there were benefits, i imagine less bloatware but this is not a rom but firmware so i am wondering if this is a edited firmware or if my phone is new if there is no sense using this if it gets updated through the phone itself.

Edit: I see what you are doing now, sorry for taking up your time, i really wish this variant was worked on more as far as rooting and twrp.

Hi, i have a t-mobile G973U unlocked (but not the officiel way bought it locked) i flashed the G973U1 firmware on it with patched odin everything went smooth and the phone booted without t-mobile bloatware but i can't make phone calls may sim can't register on the network and in software info csc code is TMB/TMB/TMB i used G973U1UEU3DTC9 firmware with USC code

Where did i messed up ?

PS : the phone isn't blacklisted
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Yes, the firmware in the original post is more than a year old, and that's because the original post is more than a year old. I only upload certain new versions - I don't do every single one. That has been fully explained in the OP and several times throughout the thread

You can flash any version that you want

Make sure your IMEI is still intact
[Samsung Galaxy S10 Guides, News, & Discussion] numpea:
Yes, My IMEI is still intact and the phone detects sim and local carriers but can't register on the sim carrier
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Make sure you're using T-Mobile's own IMEI checker, for checking if a device is blacklisted or not - 3rd party IMEI check sites always give bad information.

[Samsung Galaxy S10 Guides, News, & Discussion] Airgio:
Are you sure? I don't want to have problems with my SIM
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
As long as the phone has been SIM unlocked, as long as it's not blacklisted, not defective, and doesn't have any other problems, and as long as it is compatible with the carrier that you're trying to use, then there is no possible way that flashing a software update can give you any sort of SIM problems.

Hello thank you for the worthwhile post, am real new here and this thread made me to open an account here so that I can get my concern solved. And direct to my concern, I own S10e with model SM-G970U unlocked US with service provider SW ver. XAA/XAA/USC and current BL/Bootloader is G970USQS3CTA3 with Security Patch as at Feb 2020 and UI 2.0, my region is East Africa (Tanzania). Always am trying to update software but I get notification that my software is up to date while I know there is new version of UI which 2.1 already out to many region also security patch level is almost up to May/June depending on some regions.

My worry is may be I cant get OTA timely or I cant get it at all as I owned Unlocked version of USA and I live another region. Therefore members I need your help as if flashing my firmware to U1 will solve this problem or there is another alternative? and if U1 will solve my concern which firmware should I go with which will be relevant with my device info as described above. Thanks and Regards.
