Hello.

I have purchased Samsung Galaxy S10 unlocked phone directly from Samsung. I am using At&T carrier network on this phone. As this is the first time, i am purchasing unlocked phone, i was not aware that wifi calling, VOLTE and video calling wont work on unlocked phone ( with AT&T carrier)

There is very poor signal near my home. I really need Wiif calling and VolTE option.

is there a way that i can install At&T firmware on my phone ?

I have few questions after i install the firmware

1. After installing At&T firmware, will other sims work on my phone in future ?

2. I personally paid for the device, but sim is on business account. will this have any impact if i install firmware ?

3. after install AT&T firmware, will i be able to do any future updates without any issues ?

4. will installing this firmware, void my phone warranty ?

5. what is the difference between unlocked and locked phone ( apart from i can use with another careers )

Since this is first time, i have these questions

1. After installing AT&T firmware, will other sims work on my phone in future?

Yes. The Device is unlocked. Installing firmware intended for another Carrier will never lock the device.

2. I personally paid for the device, but sim is on business account. Will this have any impact if I install firmware?

No.

3. After install AT&T firmware, will I be able to do any future updates without any issues?

Yes.

4. Will installing this firmware void my phone warranty?

No.

However if you it take into AT&T for support and they do a check on the IMEI, they'll know it wasn't purchased from them. They'll redirect you to Samsung for assistance.

5. What is the difference between unlocked and locked phone (apart from I can use with another careers)?

An unlocked phone allows you to use SIM cards from other carriers in local or foreign countries.

A locked phone is locked to one carrier in one specific country.

Hello,

[MENTION=4786157]A_H_E[/MENTION] thanks for the message.

Below is the version of the phone

Model Number: SM-G973U1

Here is an example, via YouTube, on how and what you should see when upgrading a Samsung Device:

[Samsung Galaxy S10 Questions & Answers] Sakete:
Just so you know, just installing the firmware may not necessarily give you VoLTE or WiFi calling from AT&T. I believe it's also tied to the IMEI of the device, i.e., it needs to be an AT&T branded device. That's why I personally just went for the AT&T version of the S10 as I didn't want that hassle otherwise. And when I do need to use another SIM when traveling abroad, I'll just unlock it through an unlocking service.
[Samsung Galaxy S10 Questions & Answers] rinku2012:
Thanks a lot for your message. i will give a try

in future if i want to go back to stock firmware, how can i do it ?
[Samsung Galaxy S10 Questions & Answers] GuestK00136:
Same steps but you'll use HOME_CSC instead of CSC_OMC.

I forgot to upload that but will shortly.
[Samsung Galaxy S10 Questions & Answers] rinku2012:
Thank you. Please upload the file. in another thread i saw that we can only flash userdata file from carrier firmware without having to fully flash the firmware

do we have the user data file ?
[Samsung Galaxy S10 Questions & Answers] GuestK00136:
Everything you require is included in my instructions.

But I always recommend a full flash.

I understand having to back-up and restore can be time consuming but it will save you less hassle in the long run.
[Samsung Galaxy S10 Questions & Answers] daniel4653:
From what I remember you have to flash the correct CSC to update the carrier code. Could be mistaken as i haven't flashed with Odin in about a year.
[Samsung Galaxy S10 Questions & Answers] rinku2012:
Thank you. Do we have User data file in the files ?

can you upload HOME_CSC file also
[Samsung Galaxy S10 Questions & Answers] GuestK00136:
You don't need USERDATA :)

And yes, like I said before, I will upload HOME_CSC.

.....

It has been uploaded.

'5 - HOME_CSC.7z' is the file name.

Let's just focus on getting you back to stock firmware. AT&T can wait until later.

Did you install the USB driver I recommended?
[Samsung Galaxy S10 Questions & Answers] rinku2012:

Nevermind Odin for now.

Please restart the device.

Hold VOLUME DOWN plus POWER for seven seconds.

What happens afterwards?
[Samsung Galaxy S10 Questions & Answers] rinku2012:
i am uploading the stock firmware now. ( i forgot to press volume up to download the firmware. once i clicked on that and pressed start its working)

i will update you in few mins how it goes with stock firmware
[Samsung Galaxy S10 Questions & Answers] rinku2012:
i was able to successfully install stock firmware. but i still see that ATT/ATT/XAA' referenced on the third line

does this mean it dint stocked correctly ?
[Samsung Galaxy S10 Questions & Answers] :
Can you post a screenshot or a picture?
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
Or... You can just manually boot to recovery, do the wipe there, and then choose Reboot Bootloader to go to Download Mode. Much faster :)

Incorrect.

You ALWAYS use *non HOME CSC* when switching between U1 and U firmwares
[Samsung Galaxy S10 Questions & Answers] rinku2012:
hello,

i am confused here. how can i get back to stock firmware of my samsung galaxy s10 unlocked phone. which file should i download

after i get back to stock one, then i can look into the at&t one
[Samsung Galaxy S10 Questions & Answers] :
[MENTION=3163377]iBowToAndroid[/MENTION]

I was under the impression if we go from U1 to U, we use CSC_OMC and HOME_CSC if we go back to U1.

Let's focus on one post at a time.

I appreciate everyone's feedback but you and I started this together so let's get it fixed together.

Good?
[Samsung Galaxy S10 Questions & Answers] rinku2012:
Hello A_H_E

yes lets focus on one thing at a time. as per the below thread

https://xdaforums.com/galaxy-s10/how-to/s10e-g973u-g973u1-firmware-links-t3905852

i have downloaded U1 firmware file

U1 firmware: https://www.androidfilehost.com/?w=files&flid=290646

i have stocked it with the firmware. i dont see any changes to the kernel build or software version or anything.

i am testing the below file with AT&T user data file now

U firmware: https://www.androidfilehost.com/?w=files&flid=290645
[Samsung Galaxy S10 Questions & Answers] :
Okay, to confirm, you're using U software with AT&T Userdata?
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
Nope. HOME leaves data and settings intact, and the other one performs a wipe. A wipe is needed when swapping firmwares since the partition table is slightly different, and even if they were the same, you'd have crashes and glitches and errors galore until you wiped.

If you merely want to Odin flash a new version of the same firmware instead of doing it OTA, then you can get away with using HOME CSC
[Samsung Galaxy S10 Questions & Answers] rinku2012:
I Understood the process ( Please correct me if i am wrong)

U1 phone is unlocked ( with this i wont get wifi calling, Volte etc).

i have installed U firmware with At&t user data. i see some at&t apps and i can see video calling, wifi calling etc

Shall i install U1 firmware with At&T user data ( will i get wifi calling, Volte etc) or should i just use U firmware with AT&T user data ?

despite of what i use, will i be getting all the updates form AT&T ?
[Samsung Galaxy S10 Questions & Answers] :
Thanks for clarifying. You provided some insight on a prior thread but this is much more in-depth.

So, in this Users case, was a full flash of U software needed? Or could we have simply flashed the appropriate Userdata and CSC based on his Carrier of choice (AT&T)?

---------- Post added at 12:13 AM ---------- Previous post was at 12:07 AM ----------

1.) U1 is unlocked and no, you won't see VoLTE/WiFi Calling and other Carrier features.

2.) If you have U installed, your Service Provider SW Ver. reads ATT/ATT/XAA, and can get WiFi Calling and VoLTE to work, then stay.
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
1. If you want carrier bloat and/or specific features, then you need U firmware. You can't get any of that with U1

2. The CSC files are the exact same for any firmwares with the same build - no matter what carrier/region they're from. The only difference is the USERDATA file - that's what contains the bloat.

3. You can't use USERDATA files when flashing U1
[Samsung Galaxy S10 Questions & Answers] rinku2012:
when i am trying to install U1 firmware form the link https://www.androidfilehost.com/?w=files&flid=290646

i am getting invalid 256 Hash key and its not going further. what should i do to fix it ?
[Samsung Galaxy S10 Questions & Answers] :
I uploaded this earlier via MEGA:

It's SM-G973U1 software.
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
I have no idea. That's really not very much information.

Where are you getting the error - on the phone, or the PC? If on the PC, in what program or during what step does it appear? What are the exact steps to replicate the issue? Etc.
[Samsung Galaxy S10 Questions & Answers] rinku2012:

i am using Odion v3.13 to add the firmware
[Samsung Galaxy S10 Questions & Answers] rinku2012:
now i am getting same error with these files too

what i understood id, after i install U firmware, i am unable to install U1 firmware

how can i fix this and go back to stock firmware
[Samsung Galaxy S10 Questions & Answers] :
Let's try with a different Odin.

I've attached a newer patched version of Odin.

(Courtesy of this thread: https://xdaforums.com/android/software/patched-odin-3-13-1-t3762572)
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
It's not newer. It's just been patched, to remove the incompatibilities that would normally appear. This is the correct version of Odin to use - it can flash pretty much anything, for any model
[Samsung Galaxy S10 Questions & Answers] rinku2012:
do i need to have USERDATA files installed after installing S10 G973U firmware. I see that almost most of the AT&T apps were installed with S10 G973U firmware
[Samsung Galaxy S10 Questions & Answers] waternut13134:
I was lead to belive that ATT whitliested the IMEI numbers so only ATT branded phones could get the wifi calling and VOLTE even if you flashed the carrier firmware. Is that not true?
[Samsung Galaxy S10 Questions & Answers] rinku2012:
Hello,

i am not sure about what was happening before. but after i installed the below firmware, i was able to get into AT&T stuff. i am able to get video calling, wifi calling, volte settings. i am happy now

U firmware: https://www.androidfilehost.com/?w=files&flid=290645
[Samsung Galaxy S10 Questions & Answers] rwc95:
That is how it works normally on att. I made that mistake with my unlocked s8 tried everything out there to get volte to work and never could because of the imei deal. I just bought an att s10 had them sim unlock it and now I can have both if I want unlocked phone its just a flash away, If I want att stuff to work I have that too.

---------- Post added at 04:40 PM ---------- Previous post was at 04:38 PM ----------

You say you can see the settings now but do those features actually work. Hopefully they do for you but normally att features only work with att firmware and att imei
[Samsung Galaxy S10 Questions & Answers] rinku2012:
i can see that VolTe, Wifi calling, Video calling are working on my phone now. even signal quality is much better now as Volte is working
[Samsung Galaxy S10 Questions & Answers] rwc95:
I'm glad it works for you never could get it to work on my unlocked s8, I bought an att s10 and just had it unlocked to be safe.

Right now i am using AT&T firmware and using Wifi calling, AT&T Video calling, Volte and other at&t features on my unlocked phone

will in future when at&t releases any security updates or software updates, will i be able to get it on my phone ( AT&T firmware ) ?

[Samsung Galaxy S10 Questions & Answers] rwc95:
Your unlocked s10 should get wifi calling and volte on tmobile with the firmware it comes with. You will get better signal with the tmobile firmware though. Att is the only carrier that makes it a pain to make stuff work. When I was on tmobile with my unlocked s8 I got all features with either firmware.
[Samsung Galaxy S10 Questions & Answers] AHE_XDA:
Absolutely. My pleasure. I'm happy to see everything worked out.
[Samsung Galaxy S10 Questions & Answers] winb83:
You can't have both VoLTE and WiFi Calling on a non-AT&T phone on AT&T unless it's an iPhone. I was in your position. I activated AT&T on my iPhone and had both then moved it to my Note9 and it was one or the other. Sorry to break it to you.

I did flash AT&T firmware to my phone and it still doesn't work. The WiFi calling will pop up an error message.
[Samsung Galaxy S10 Questions & Answers] hans8705:
[MENTION=2691759]winb83[/MENTION]

i had this same issue, and after speaking with several people from at&t tech support, i finally spoke with someone who knew a work around. they assigned a not-yet-in-use imei number to my account, an at&t branded device imei number, not my unlocked imei number, and now wifi calling and volte work great. they related there may be an issue in the future, but for now, its a quick fix. they also told me to request an update from samsung, but wouldnt provide any more details on what they were referring to.
[Samsung Galaxy S10 Questions & Answers] Tel864:
I wouldn't be surprised if a future update from Samsung breaks it sgain.
[Samsung Galaxy S10 Questions & Answers] winb83:
This isn't reliable because it's not something anyone can consistently get done. For the normal user what you did isn't possible. Not every CSR is basically gonna hack your account and provision it for an IMEI for a phone you don't actually have and make it work.

The problem is AT&T's provisioning. When I had my account provisioned for the iPhone I could get WiFi calling to work on the Note but not VoLTE. When I got my account provisioned for the Note9 WiFi calling stopped working but VoLTE started working.

AT&T basically told me tough luck that's not our device so I canceled my service after 3 days.

It's not a Samsung issue in that sense. It's AT&T provisioning. Apple forces all carriers to support all those features on any phone. Samsung doesn't. This is why you can use an unlocked iPhone on AT&T and all those features natively work but on an unlocked Samsung phone they don't.
[Samsung Galaxy S10 Questions & Answers] Tel864:
Didn't say it was, I only meant that a forced and a fix like that isn't going to stick. If I was the employee that did that little IMEI trick, I'd probably start worrying about my job because I guarantee that it broke every company rule in the book.

[Samsung Galaxy S10 Questions & Answers] beethoven1854:
I done the same with my Unlock S10 plus; Converted it from U1 to AT&T U firmware. Are you guys still on ASBA? Anyway to update to ASD3? There is also a new biometrics patch that just came out yesterday via the Galaxy Store. It is supposed to improve fingerprint sensor. I am having trouble installing that update. I can see the update poped up but it is from Galaxy store inside my secure folder. It just says "Couldn't update" when I try to do it.
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
Any user can manually install any version via Odin, regardless of which carrier firmware you're on - as long as you're not trying to downgrade bootloaders
[Samsung Galaxy S10 Questions & Answers] beethoven1854:
I found ASD3 for T-mobile on SamFirm. I plan to upgrade using this firmware via Odin. Can I pick HOME_CSC to avoid data wipe for this one? What about USERDATA file? I assume I can just not use a USERDATA file for this as well.
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
Yes, use HOME. And yes, skip USERDATA

[Samsung Galaxy S10 Questions & Answers] JohnnyXCG:
Thank you.

I got my visual voicemail working now, just keep trying setup.

One more question, after flashed by Odin, the system OTA update always telling me I'm on the lastest firmware, but actually it's not.

I flashed to SAT version released on Feb, and the latest one is SD3 version I guess? And they system said I'm the latest one.

How do you update in the future?
[Samsung Galaxy S10 Questions & Answers] rinku2012:
yes even i am seeing the patch level is on Feb 1 2019. even for me it says software update is up to date

how did you installed the latest patch ?
[Samsung Galaxy S10 Questions & Answers] JohnnyXCG:
I installed the latest SD3 by downloading the file into my MicroSD card and install in recovery.

You can find the files on firmware.science website.

But you need to wipe the data before the install.

I'm still trying to find a way to update without wiping data.
[Samsung Galaxy S10 Questions & Answers] rinku2012:
did AT&T really push the update ?. i am seeing that at&t latest update is for path level that was on Feb 1st 2019
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
Just flash Odin files and use HOME CSC

I've been having the hardest time trying to figure out just how to get this OTA. Nothing works. I've even had a Samsung and AT&T rep on a conf call. This shouldn't be that difficult.

is this right one ?
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
I'm not 100% sure what the correct one should be, or if it even matters when it comes to OTAs. Are you able to get OTA updates, with the phone in its current condition?
[Samsung Galaxy S10 Questions & Answers] rinku2012:
i have only February 1st Patch. when i press of software update, it shows as software up to date
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
Then no, you're not getting OTAs either. Is AT&T your carrier?
[Samsung Galaxy S10 Questions & Answers] rinku2012:
yes, AT&T is my carrier. i have orginally bought Samsung unlocked S10 phone. i have installed the U firmware from the below link

U firmware: https://www.androidfilehost.com/?w=files&flid=290645

I havent installed AT&T User data

will this be any problem for my OTA updates ?
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
That might be why you're not getting them, but I don't know for sure
[Samsung Galaxy S10 Questions & Answers] rinku2012:
can i install AT&T user data without loosing my data ?
[Samsung Galaxy S10 Questions & Answers] iBowToAndroid:
I have no idea. But there are plenty of ways to back up data these days, so doing a factory reset should never be a problem for any user. Everything can very easily be restored afterwards
[Samsung Galaxy S10 Questions & Answers] Lavman72:
In case anyone is interested. Another thread in the S10 forum with Odin files. I went ahead and updated. No problem. Battery life seems better, fingerprint scanner seems more responsive.
