Thank you a lot for your quick revert.. Lemme try and will keep you posted.

Hellow members this is to inform you that I successfuly update my firmware up to June and my phone is running smoothly with new UI 2.1
[Samsung Galaxy S10 Guides, News, & Discussion] newuzer1:
Anyone have a source for G973U DTE8 w/ ATT userdata? Most recent ATT userdata I could find earlier in this thread is CTB3.

I see G973U DTE8 CCT (comcast), CHA (xfinity), SPR (sprint), and VZW (verizon) is published on samfw among others.

To switch from U1 to U ATT, from what I understand, I can download any of those 4 packages and use:

- AP, BL, CP, CSC_OMC_OYN from that download

- ATT userdata (if I can find a source)

If I have this wrong, please let me know. I considered installing the VZW but I'm not sure if carrier specific bloatware is loaded (I want ATT) on U firmware or just U1.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
1. By definition, U1 is bloatware free. So carrier bloatware is never loaded on U1 - only on U

2. I don't have access to the TE8 ATT USERDATA yet but I'll upload it when I do. Remind me in a week if I haven't posted it by then
[Samsung Galaxy S10 Guides, News, & Discussion] newuzer1:
Perhaps I used the wrong language...carrier specific firmware maybe?

anyway, I'm still not certain if U firmware will load carrier specific firmware/software based on SIM inserted.

if it does, I don't understand why there's even different CSC variants of U. or U1 software for that matter. what's the point of installing specific CSC firmware if it'll configure itself to the SIM inserted?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Not every phone will automatically perform the firmware conversion, for U firmware
[Samsung Galaxy S10 Guides, News, & Discussion] newuzer1:
Do you know if VZW will do the conversion for ATT?

I have U1 DTC9 now. Latest U ATT I found to download is CTB3. Not sure if that'll cause problems since its an earlier build even though they're both bootloader version 3 (i believe). Was thinking of installing U VZW DTE8 and putting in an ATT sim hoping it'll do the necessary conversion.

---------- Post added at 07:02 PM ---------- Previous post was at 06:44 PM ----------

UPDATE...

Well I'm currently rolling the dice on installing ATT CTB3...
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Why would you do that? Installing U1 is part of changing carrier firmware anyway. Why not just jump directly to installing AT&T firmware (considering you already have the firmware) and skip the guessing game? What sense does it make to install Verizon and hope that it converts, when you could just install AT&T and not have to worry about whether it will convert...?
[Samsung Galaxy S10 Guides, News, & Discussion] newuzer1:
I was already on U1.

I went ahead and installed ATT CTB3. I was hesitant because I wasn't sure if it'd create problems going from DTC9 down to CTB3 (an earlier build/release). It installed fine and confirmed in settings.

However, when I check for software updates (currently ATT S10 is DTE8), it says it is already up to date. I vaguely recall this can be an issue, that in some instances when changing firmwares OTAs aren't available. Anyway to fix this other than having to manually update? I def don't want to be stuck on CTB3 nor have to find updated downloads and manually install.

....

Anyone have some insight into this? Would greatly appreciate any guidance. From what I read, I should be able to update as long as ATT released this version (which it did). Man, I can't figure this out.

.....

Alright, on a whim I did a factory reset (again, did one before loading CTB3), rechecked for download...and now its downloading some update...not sure which version yet. So for others, try a factory reset if it incorrectly says the software is up to date (no updates available).

Odin Flash

I've had a hard time finding a solid answer... I have a G973U1 Factory Unlocked phone that in Tech Support, Samsung flashed a Sprint ROM over my factory unlocked ROM. (So angry.. and they won't remedy)

Can I Flash a U1 unlocked ROM back on my phone, without unlocking the bootloader using Odin and an XAA ROM? I've read that you suggest that the G973U ROMs can be cross flashed... (The problem I have is that there is no Allow OEM Unlock option in this new ROM)
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
1. The very first paragraph of the OP tells you (not "suggests") straight up that they can be cross flashed.

2. U and U1 models can't be bootloader unlocked. But that's irrelevant because bootloader unlocking has never been required in order to flash official OEM firmware, on any model device
[Samsung Galaxy S10 Guides, News, & Discussion] titanium3164:

Thank you!

Everything worked out perfectly, once I did a factory reset on the phone prior to the flash.
[Samsung Galaxy S10 Guides, News, & Discussion] chrisswistak92:
Hello, I have an unlocked AT&T S10 running Android 9. I would like to update the phone so that carrier firmware switches when changing the sim card. Will these firmware files accomplish this, or do I need an Android 10 firmware. Right now, when I put a Tmobile sim card in, it does not switch firmware, where other devices have rebooted and updated.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
I forget when the feature was added, exactly. But assuming that you're still on bootloader 1, then yes, that feature should become available as soon as you update to bootloader 2 or later
[Samsung Galaxy S10 Guides, News, & Discussion] chrisswistak92:
Thank you. Sorry for the noob question, but how do I update to bootloader 2? Is that accomplished by updating the firmware using the OPs link?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
I don't think I have anything higher linked in the OP, the reason for which is explained in the OP. The OP and thread already detail where to find newer firmware if desired

G973U1 help

Hello,

I have a Sim unlocked Sprint Galaxy S10 that I am trying to flash the unlocked firmware onto. I have ODIN 3.14 as well as the firmware downloaded from SamMobile for the August Security update G973U1UES4DTG1_G973U1OYM4DTG1_XAA for the Firmware. I tried to flash it onto the phone but was given SHA256 is invalid. I tried to factory reset the phone then try to flash it onto the phone. I am not sure what else to try to flash the firmware onto the phone. Any help or advice would be greatly appreciated this is my first flash on a phone so kind of a noob to this. Thank you again.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
SHA256 error means you're not using Patched Odin

Trying to upgrade to One UI 2.5

I'm currently on U1 firmware and the software update for U1 is stuck at TH3 while for U the firmware is at TH7 (One UI 2.5). I would like to know which firmware should I install from SamMobile in order to not be carrier locked and still be able to switch between my T-mobile and Verizon sim cards. I would really appreciate the help if you could help me with this problem.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
It's already been very clearly stated that U and U1 firmware is 100% interchangeable. You can flash any version that you want at any time. U1 is not "stuck" on TH3. It has the exact same features that U firmware does

AT&T USERDATA for bootloader level 4 has (finally) been added!
[Samsung Galaxy S10 Guides, News, & Discussion] tsoychik:
Hello,

Does anyone have a firmware and USERDATA for Cricket for a level 4 bootloader?

Trying to convert my G973U1 to Cricket version, but Odin fails with "fused 4 binary 3"

Thank you.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You didn't see the post literally right before yours...?
[Samsung Galaxy S10 Guides, News, & Discussion] tsoychik:
I have tried using files in TB3 as well as the USERDATA in TF6, but getting "fused 4 binary 3" error. I thought that it was due to the newer bootloader that I have on my phone.

Do you know if I am doing anything wrong and how to pass that error message?

Thank you.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Yes, it is due to the newer bootloader. You have bootloader 4 but TB3 is bootloader 3
[Samsung Galaxy S10 Guides, News, & Discussion] tsoychik:
I contacted Samsung support. They told that they are rolling out Android 11 to S10 soon. This has resolved WiFi Calling issue with my unlocked S20+. So hopefully I can get that functionality after an upgrade to Android 11 like with S20+.

Hi flashed my S10e to android 10 from android 9 , its XAA CSC model G97OU1 I believe, but i used home csc and now says your current software version isnt supported visit a service centre. So I gather ill need to flash it when 11 comes out with one ui 3.0..... I'm using Frija to download the software, any idea when 11 comes out and should i not use the home CSC so i can get OTA updates thanks .
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
It doesn't matter which CSC you use. Neither one is going to prevent you from getting OTA updates.

I have no idea when Android 11 will be released for the S10 series
[Samsung Galaxy S10 Guides, News, & Discussion] QueenLizzy:
Thanks do you know why i got that message in OTA updates? your current software version isnt supported visit a service centre. Far as i can tell phone working fine...except that Patch Jan 2021
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You would have to post pictures or screenshots of all of the info found under Software Information, in order for me to know

Hello,

I am using US Cellular and I have an unlocked Galaxy S10 G973U1. I wanted to use Wifi calling, but can't because of it being unlocked. So I downloaded USC CSC G973U1OYM5GUD1 and used HOME_CSC_*** with odin. When I restarted the phone, everything was the same, but it did have that firmware on it. What am I missing? Any help would be appreciated.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
What is "HOME_CSC_***" ??
[Samsung Galaxy S10 Guides, News, & Discussion] arthurwv:
Sorry, in Odin in the CSC section, I used HOME_CSC_OMC_OYM_G973U1OYM5GUD1 instead of CSC_OMC_OYM_G973U1OYM5GUD1
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If you want wifi calling, you either need to convert to full U firmware, or flash the U CSC along with the rest of the U1 files
[Samsung Galaxy S10 Guides, News, & Discussion] arthurwv:
Oh, so I need to download the U firmware and just use the U CSC. I can use the U CSC with U1 files? I didn't think that would work. And I use the HOME_CSC... to keep my data? Thanks for helping this noob. I tried figuring this out searching before posting, but I was just confusing myself more lol.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If you do the full U conversion, then you need to wipe data
[Samsung Galaxy S10 Guides, News, & Discussion] arthurwv:
I don't want to do the full U conversion if I don't have to. If I can get Wifi calling just using the U CSC and not losing the data, that would be preferable. So I should use the U CSC with the other U1 files I had already downloaded?
[Samsung Galaxy S10 Guides, News, & Discussion] zorzgeo:
Hmmm. Strange situation.

I have buy G973U in Europe (Single SIM) with XAA/XAA/ATT (Android 10, ui 2.x) out of the box and no one update for a couple of a days till i change CSC to USC and have a couple updates and restarts to June 2021 sec. patch and Android 11/UI 3.1. After that i have turned csc to XAA via SamKey and i am waiting for July update to see what will happen. To be updated or not...

What is Your suggestion to me to stay on what CSC and have a regularry updates to my G973U model?

TNX
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Stay on whatever CSC gives you updates. But if the model number is G973U, CSC XAA probably will not give you updates because XAA only exists for model G973U1
[Samsung Galaxy S10 Guides, News, & Discussion] zorzgeo:
What unbranded CSC to use it (if existss) for 973U model or it must be the specific network code?

Tnx
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
None. Unbranded is only G973U1
[Samsung Galaxy S10 Guides, News, & Discussion] zorzgeo:
Ok, i understand, but wondering what's happening. OOB (vacuum box with the Samsung warranty seal) was (Settings-About phone) SM-G973U and XAA/XAA/ATT :(

Any suggestion which CSC to choose as the least invasive about network bloatware?

TNX
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Least invasive means no bloatware.

The firmware with no bloatware is G973U1
[Samsung Galaxy S10 Guides, News, & Discussion] zorzgeo:
Ok.

TNX

That's mean i'm stucked :(

P.S. 1 stupid question. Is there a way to and how to change model mark from U to U1 or that's how is?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
How are you stuck? Changing from U to U1 is the entire subject and purpose of this thread
[Samsung Galaxy S10 Guides, News, & Discussion] zorzgeo:
Ok.

Now, my phone CSC is XAA/XAA/ATT.

What i must do next is to download U1 XAA firmware and flash it via Odin and turn my U phone into U1 or what (sorry, been little confused because i think i have a little knowledge :( but i haven't).

TNX
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Yes

Thank You so much for Your patience. I will post a results after f/w flashing.

I have downloaded 'SM-G973U1_2_20210531141437_zuv5zpibid_fac' f/w with Frija and successfully d/l it in Odin but sucks :(

Tried different cables but always the same.

Any suggestion?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Setup Connection is a USB error. If you are using a desktop, make sure to use a USB port on the rear, not on the front. Use high quality OEM cable and high speed 3.0 or 3.1 USB port. If still fails, use different PC

Is there a way to get both of these to work by changing the firmware?

Hi all, I've bought a refurbished Galaxy S10 off Amazon to use here in New Zealand. the model number is SM-G973U1. Everything appears to work fine including with my carrier but everytime I start my phone it tries to activate itself with the carrier (but fails) - once I exit that screen everything works fine. I also get OMADM messages... Does anyone know what this means and can I get rid of it? Would I be able to flash another ROM on it that would resolve it?

Any help appreciated.

Thanks

You would need to post screenshots or pictures, in order for us to better understand
[Samsung Galaxy S10 Guides, News, & Discussion] amdaman:
Hi, sorry I couldn't get a picture but I found out it was the Sprint activation on start up. I search a lot and had to use adb to remove OMDAM apk:

pm uninstall -k --user 0 com.sec.omadmspr

It seems OK now but I don't know why I had this anyway because I downloaded the latest SM-G973U1 XAA rom which should not have any carrier specific software on it?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Your device was already set to Sprint customization before flashing it. Or maybe you flashed G973U1 SPR, not XAA
[Samsung Galaxy S10 Guides, News, & Discussion] amdaman:
I used Frija to download XAA but it looks like it has downloaded OYM ... do you know where I can get the XAA or unlocked firmware? Could I download an 'unknown' firmware from sam mobile?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If you entered "G973U1" and "XAA" into Frija, then you got exactly what you were supposed to
[Samsung Galaxy S10 Guides, News, & Discussion] amdaman:
When I go into the service provider software version though it is saying the following:

SAOMC_SMG-G973U1_OYM_SPR_RR_0009

SPR/SPR/TMB

I take it the Sprint software is still there and there is nothing I can flash to get rid of that? Sorry for all these questions.. it was much easier when I had the S9
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You would need to insert a different American SIM in order for it to change to a different configuration
[Samsung Galaxy S10 Guides, News, & Discussion] magnumpi1:
Well, I think I am going to try changing my firmware from AT&T to U1 with XAA. Since my IMEI is working with wifi-calling, I am hopeful that it will remain working after the firmware update. I have read that by changing to the U1/XAA firmware, the call and text from other devices feature works.

I have some reservations that hopefully someone can clear up. I have read other threads, which say you can no longer change from a carrier firmware to unlocked or vice versa and that if you have you needed to change back before the next OTA update. These post were back in 2018, so I doubt that is still valid???

I downloaded the firmware with Frijia and will use the non home CSC (which will wipe phone). I removed my gmail account on the phone as was suggested in another thread.

In that same thread it was suggested that I need to use the Prince Comsy version of Odin, but then I read about there being fake version of this version. Can someone point me to a legit download for the odin version I need?

Lastly, in that same thread, it talked about having to use Google Platform-Tools (ADB) and Canadian HOME_CSC (either Bootloader v1 or Bootloader v2), which I do not see suggested any place else. The thread I am referring to is:

https://xdaforums.com/t/snap-guide-...r-switching-and-flashing-unlocked-fw.3625817/

I know that is for the S8 and I have an S10, so maybe that's the difference here.

I just want to make sure I have the right files and program before I start.

Thanks a million to anyone who is able to offer some small guidance.
[Samsung Galaxy S10 Guides, News, & Discussion] magnumpi1:
I think I found the legit patched Odin:

Patched Odin 3.13.1

For those looking for a modified, modded, or patched odin that is a newer build than all the fake and renamed prince comsy 3.12.3 versions floating around. I patch recent Odin versions to offer similar functionality to the princecomsy; in that...

xdaforums.com
[Samsung Galaxy S10 Guides, News, & Discussion] magnumpi1:
I decided to go ahead and try it.

Didn't apparently need Google Platform-Tools (ADB) and Canadian HOME_CSC (either Bootloader v1 or Bootloader v2)

However, even though wifi calling still works, the call and text on other device feature does not. Before at least it would pass on text, but not phone calls over wifi, now it will do neither and only passed on calls and text while connected to the watch via bluetooth.

I want to go back to ATT firmware, but I am having trouble finding U firmware with ATT CSC I downloaded the latest Userdata file from the OP link, but it is only one file. How do I get the other 5 I need for the ATT carrier version? This is not clear to me.

Thank you
[Samsung Galaxy S10 Guides, News, & Discussion] magnumpi1:
I think I figured it out.

As I mentioned in the previous post, I downloaded the ATT userdata file from the OP link on page 1. I then used Frijia to download the other files, using my model number and the USC CSC. The reason I used that CSC is because I determined that it had the same version/date firmware as the ATT userdata file. My plan was to replace the userdata file that came with the frijia download with the ATT user data file.

Before flashing back to ATT, I tried turning on call and text on other devices this morning. It actually turned on this time and pretty much works, so I am going to leave it for now.

If I do decide to flash back to ATT CSC, is my plan above correct and would I also have to do what post 172 states first wipe/flash U1 firmware, etc......

Post 172:

Here's the procedure to convert carrier firmware on a U model:

1. Wipe in recovery -->reboot bootloader-->flash U1 firmware

2. Upon boot, watch for the popup that says "your device will restart to apply new carrier settings", and do it. Make sure your desired SIM is inserted for this step.

3. After that finishes, power off, boot to download, and flash desired U firmware with non HOME CSC and desired U USERDATA. That should give you all the desired carrier settings - and bloatware.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
No. That's for converting from one carrier's bloatware to another carrier's bloatware
