1. It's the fact that the rootable S10s don't have CDMA support

2. Yes, same for N10

Can anyone confirm if I just got an AT&T branded G973

U

device and unlocked it and want to use it on Verizon with the Verizon specific apps (bloatware), do I need to reflash the full latest firmware with VZW USERDATA or is that no longer required with the latest update?

I read somewhere after a certain August update supposedly they are all now multi-CSC and if you insert another carrier's SIM card it will restart the device and install the respective apps and enable the features (wifi-calling/HD voice/etc...) for that carrier. Am I understanding that correctly or is that only relevant to the unlocked G973

U1

devices?
[Samsung Galaxy S10 Guides, News, & Discussion] red_dog007:
Just to clarify, I have the Sprint branded S10. I want to go to TMobile. If I flash U1, will this give me access to B71 and VoLTE? Or do I need to flash the specific T-Mobile U firmware?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Whether a given device performs the carrier firmware conversion seems to be hit-or-miss. Even if it doesn't do it automatically, you can do it yourself manually, using the steps in the OP

I don't think anyone has a way of confirming that. It's more of a try-it-and-see type of thing. Also remember that the phone needs to be SIM unlocked before proceeding
[Samsung Galaxy S10 Guides, News, & Discussion] open1your1eyes0:
Ok great! But just to clarify, CSC code changes are no longer required to get the S10 working with the respective carrier's apps is that right? Just flashing the firmware and carrier USERDATA?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
A "CSC code change" has never been required. I'm not even sure what that means because the CSC files are identical for every single Samsung U and U1 model
[Samsung Galaxy S10 Guides, News, & Discussion] open1your1eyes0:
Sorry I think I realized I am actually coming from a Galaxy S8 where we had to manually edit the EFS file with a different CSC code to get other carrier firmwares or USERDATA to flash (referencing this process) - https://xdaforums.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487

Looks like Samsung made all Galaxy S10's multi-CSC so it automatically adjusts based on SIM-card, I think we don't have to worry about that anymore. Surprisingly nice of them but I'll take it. :) :good:
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
That process has never been needed. The firmware conversion steps given in the OP of this thread have always worked on every U model - all the way back to the S8. And I've included the steps in the OP of every single one of my U device firmware threads.
[Samsung Galaxy S10 Guides, News, & Discussion] StoneyJSG:
Only exynos variants of the phone can be rooted. All U.S. models which are snapdragon variants (with the exception of the Sprint 5G version), cannot be rooted.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Well not exactly. There are Qualcomm models that can be bootloader unlocked and rooted, but they're not US models

G973U from Sprint to G973U1

Hello. Can I flash Firmware U1 to a U from Sprint?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Of course.

But be aware that it will still only work with Sprint service, if the device hasn't been SIM unlocked yet
[Samsung Galaxy S10 Guides, News, & Discussion] pedromorey:
Thank you for the quick reply.

Of course, I understand. Once I unlock it and flash the U1 firmware it will become a "Unlocked by Samsung" G973U1.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If it is truly SIM unlocked, then yes. Many users seem to think that the SIM unlock can be performed simply by installing the U1 firmware, which is not correct - just wanted to make sure you were aware of that
[Samsung Galaxy S10 Guides, News, & Discussion] pedromorey:
Exactly! Don't worry I am aware of that. By any chance you perform unlocks? I was thinking using Chimera Tool to read the code, but if you recommend something else... Im all ears.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Sprint phones don't have, or use, unlock codes - they never have and never will. That's why it doesn't ask you for the code when you insert a different SIM. SIM unlocking a Sprint phone is much more complicated and difficult than a simple little code.

I own a business that performs SIM unlocking and other software-related services. So yes, we would be able to do it for you
[Samsung Galaxy S10 Guides, News, & Discussion] pedromorey:
I did not know that. Well I am interested. How can we do it? And how is it gonna cost me?
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
Anyone know if wifi calling still isn't supported for att/cricket on U1? When I had an S9 and switched from the cricket rom to U1 I lost it. Just wondering. Kinda wanna flash to U1 on my cricket S10 but kinda need the wifi calling right now.

Flash Unlocked S10 to AT&T Firmware

[MENTION=3163377]iBowToAndroid[/MENTION] I would appreciate your assistance if possible, I have not had an Android Device since the HTC10, currently have 2 phones and I would like to switch 1 from iOS back to Android. Purchased an Unlocked S10 from Amazon on Black Friday unaware that things like VOLTE and Visual Voicemail would not work out of the box.

The device is a Samsung Galaxy S10, SM-G973UI, box lists the model as SMG973U1ZKAX.

I would like to load the AT&T retail firmware so that VOLTE and Visual Voicemail will work, aware that I may need to manually have AT&T edit the IMEI to get WiFi Calling working. Hoping that you can help me identify which files I will need to flash the AT&T firmware with ODIN.

Also hoping that you can confirm whether or not I would be able to flash back to the stock unlocked firmware in case I decide to return this device to Amazon if I can't get the features working as intended. If possible which files would be needed for this as well?

I thank you in advance for your assistance, its greatly appreciated!
[Samsung Galaxy S10 Guides, News, & Discussion] brandox0:
I have a G973U, if I live in Colombia would I have to use the G973U1 firmware?

I have a problem, when I try to update from the settings it says "Your current version is not supported. Visit a service center".
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
All of the needed files are already linked in the OP
[Samsung Galaxy S10 Guides, News, & Discussion] samphonefan:
I will say that based on my experience at least, VOLTE, visual voicemail and wi-fi calling worked for me without any ATT intervention whatsoever. After flashing the ATT firmware, the only thing that didn't work is video calling using the native dialer, which is not a big deal for me at least. The link the OP posted does have the files you need, although it is for a firmware version that is slightly older.
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
Are U roms universal? Like say, I'm on att/Cricket, could I flash to the t-mobile U rom and still keep wifi calling and such? I know you lose it on U1, but what about regular U? I just want to move to android 10 and I don't see it coming anytime soon for cricket, despite att releasing it.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Yes, they're universal - that's the great thing about them. You can flash the T-Mo version (sans USERDATA and using HOME CSC) and you should be upgraded perfectly fine without having to wipe.

Only possible drawback is that if AT&T doesn't end up getting that exact same build eventually, you would need to re-flash to one of their official Android 10 releases in order to get further OTA updates
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
Which I know are hard to find specifically which makes me very hesitant to do this. Cricket even harder, as it's own thing and doesn't follow along with att unfortunately. If it did I'd have the update by now since it's already released for att.

---------- Post added at 07:13 AM ---------- Previous post was at 06:34 AM ----------

Also, what's the chances you think that crickets build will be different Numbers? It looks like all the ones released so far are the same.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Huh? No, AT&T hasn't gotten the Android 10 update yet. And yes, Cricket devices always get the exact same builds as their AT&T counterparts, although they may not necessarily be released at exactly the same time
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
Yes it's out. People on reddit have been getting ota and a Google search also shows. So, if it's the same exact build number, then I shouldn't have any problems flashing the T-Mo one and getting future updates, I just would if AT&Ts build number was different?
[Samsung Galaxy S10 Guides, News, & Discussion] samphonefan:
It's definitely released, my spouse's ATT phone received the update yesterday. (Galaxy S10) I however didn't get it, as expected, since for whatever reason, my OTA updater is broken. I've tried moving the date forward too, but I still get the software is up to date notification. Will have to flash the new firmware I guess.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Ohh okay, good to know. I hadn't heard or seen anything about AT&T's update rolling out and when I checked yesterday, AT&T hadn't updated their software update page yet. Now they have updated it, showing that the OTA began yesterday.

And yes, T-Mobile is getting the same Build.
[Samsung Galaxy S10 Guides, News, & Discussion] samphonefan:
Yes they have updated the page. Will you be posting the build files here by any chance? :)
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
I took the plunge and decided to just flash the T-Mobile rom. All is well, except for some reason even though I didn't use home CSC it decided not to wipe my phone. I manually wiped anyway because I was planning on that but yeah, was a little weird. If it wasn't for the notification telling me Android is upgrading, I'm not sure I would have even noticed a difference at first. Anyway, now that I've done this I'm a little worried about receiving updates from AT&T/Cricket in the future. Right now they're on the same build number, but who knows if they will skip forward to something else or not in January. Too bad it's such a PITA to find their files.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
The USERDATAs, yes

That's super odd. Don't think I've seen or heard of a device not being wiped when the regular CSC is used. Updates should work perfectly fine, as long as you stay on a build that AT&T has actually rolled out
[Samsung Galaxy S10 Guides, News, & Discussion] StoneyJSG:
Is there a way to get the user data off the build I am on now?
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
Yeah , at first I thought something went wrong because it actually just went to recovery and displayed some message that I didn't quite understand and so , confused, I just rebooted and carried on. I got it from Frija so not like it was some shady deal or anything lol. But yeah, I checked, and AT&Ts build number is the same as everyone else's right now for this update, so that means I'm good to go and will still continue getting the proper updates from att/cricket?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You should, yes
[Samsung Galaxy S10 Guides, News, & Discussion] samphonefan:
Thanks, looking forward to the USERDATA file. I'm waiting till the weekend to flash, need to gather all the files first.
[Samsung Galaxy S10 Guides, News, & Discussion] samphonefan:
Has anyone had success with finding the firmware files for ATT, specifically the HOME CSC files? I checked the usual firmware hosting sites, they all have G975USQU2CSKP but not sure which one is for ATT. I was looking for the USERDATA file as well, but in my case, i.e. upgrading to Android 10 without wiping data, I don't believe I need the USERDATA file.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
There is no such thing as "AT&T firmware files". The only thing that changes from carrier to carrier is the USERDATA - nothing else. If you're already running AT&T bloat etc, then just flash SKP with HOME CSC and sans USERDATA.
[Samsung Galaxy S10 Guides, News, & Discussion] samphonefan:
Thank you for the clarification! This is what I figured out as well later, after making this post a few days ago. Just wasn't sure that this would lead to a data wipe, but it doesn't look like it will, based on your post. Thanks again!
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
Then why do some people act like you might lose updates because att might push a different version than the rest? Unless you just meant what you said in the context as in att doesn't make them available.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If you flash a version that AT&T hasn't/doesn't push out as an official update, then no, you won't get OTAs because the phone will think you're running "unapproved software". So you would just have to flash their official version once it's released, in order to be put back on track for OTAs.

But in this case, AT&T *is* getting SKP, so you don't need to worry about it

Changing from U firmware to U1

Hello. Please I'm on U firmware at&t stock and I would like to flash it. Dont know which is better, flashing it to a U1 firmware which is at&t or just still using the U for another carrier because I can't find at&t U firmware. Which is just a better option and safer. My phone is Sim card unlocked though not locked to the at&t network
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
Is there user data available for cricket yet?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Can't find it? It's linked right in the OP

Yep. Linked right in the OP
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
All I see is Verizon userdata
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You're not looking hard enough. There are no less than 5 Cricket USERDATAs
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
Ahh, sorry. I do see them now. I never actually use them anyway. What are they for exactly? I usually just leave it blank. I mean it sounds sorta self explanatory but it probably isnt.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
USERDATA contains all the carrier bloat. They're used for converting from U1 back to U firmware (or from one carrier's U firmware to another one's)
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
AT&T and Cricket USERDATAs added for build SKP (Android 10)
[Samsung Galaxy S10 Guides, News, & Discussion] carnivalrejectq:
I see. Not using userdata is why my phone was not properly resetting after flashing U other times. Weird. I've never seen anybody mention this issue before.

And all the confirmation that you need is right here in the thread. Lots of people have already done this to their device
[Samsung Galaxy S10 Guides, News, & Discussion] tombepa:
So on the Sam Mobile site I see they posted the firmware for the U1 as these for Android 10. Can I flash these to the Verizon G973U? I am assuming I would just use the PDA and CSC slots in Odin correct? Been a while since I used Odin, like years.

PDA G973U1UES2CSL1

CSC	G973U1OYM2CSL1
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
There's a lot more involved than just PDA and CSC. If it's been that long since you've used it, I would highly recommend reading several of the "Basic Odin flashing"-type threads that have been posted here on XDA in the past 2-3 years

Happy to report that my XAA S10+ on which I flashed ATT firmware couple of months ago successfully updated yesterday via OTA. No complications so far that I've seen, just hugely relieved that my unlocked phone is finally almost behaving like a model purchased from ATT. Big thanks to all the experts here on the forum who helped me learn, in particular [MENTION=3163377]iBowToAndroid[/MENTION] . Now I don't have to haunt these forums anymore in search of new ATT firmware files lol.....
[Samsung Galaxy S10 Guides, News, & Discussion] esetleges:
Hey there,

Read severeal pages of this (and other) topic(s) although still did not get some basics what I need. May someone help me with these questions below:

1) Main question: Given an unlocked AT&T S10 (which sold as Factory Unlocked by Amazon). Phone will be used out of US, and I wish to have stock -U1 firmware with- OTA(!) updates. Is it possible to flash U1 then go only with OTAs?

2) Which firmware(s) should be downloaded for? There is one big file at U1 (from last March) and there are many others in U versions -seems they are non combo/cumulative-. And do I need something else then those things?

At this moment phone has this: G973UZBAATT | built PPR1.180610.011.G973USQS1ASD9 that is somewhere april/2019

3) May anyone has exprience with jOdin3? Got at this moment only a Mac around :()

Thanks for your respondings in advance:)
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
1. Yep

2. Since the device still has bootloader 1, you can literally flash any U1 version that you want. You just can never go back to any bootloader 1 version if/once you decide to flash a bootloader 2 version

3. No, no experience with that
[Samsung Galaxy S10 Guides, News, & Discussion] esetleges:
Thanks for responding!

1) Cool

2) Ok, guess here I miss that basic knowledge (still stuck up at "how to do iOS 1.1.3 jailbreak" ~;D)

QUESTION:

A) Your uploaded U1 firmware is bootloader v1 so that is fine over mine v1 (ie I can go over v1 with v1 or any higher ones - just never step back with bootloaders)

OR

B) I should find and flash a U1 firmware with bootloader v2 over mine v1 (And get always higher numbers of bootloaders, means there are total 5 shots)

3) As I see right now there is significant possibility to get unexpeted errors, even I could complied the lastest Heimdall for supporting jOdin3. Have to find some Windows (or go with Bootcamp)

And again thanks for responding about basics.

Cheers!

Is it possible to flash my Galaxy S10, without enabling "OEM unlock"? Because it looks like, that it is removed
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
It's not present on U or U1 models. So yes, it's possible
[Samsung Galaxy S10 Guides, News, & Discussion] LolestKeker:
So, I do it just without enabling it? With regular method? Wouldn't it brick it?

Yes, regular method

No, it won't brick

(Sorry if I am too annoying, first time flashing a phone)

---------- Post added at 07:28 PM ---------- Previous post was at 07:21 PM ----------

And very last question

"Regular method"

1. Enabling USB debugging

2. Going into download mode

3. Open Odin on pc

4. Set files for U1(I want to get rid of att, bcs I am out of country and cant get updates)

5. Start flashing it

6. Finished

Right?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Debugging isn't needed. Otherwise, yes.
[Samsung Galaxy S10 Guides, News, & Discussion] LolestKeker:
I didn't touch anything else in dev options except the USB debugging. And I didn't do anything to phone either. So without doing literally nothing, I just go to download mode, and set flashing via Odin. K thnx! I hope I will not brick it. If what I saved my firmwares name, and I hope it will help if I soft brick it. Thnx for your work!

anyone can please share firmware download link for G973U1 - I have to flash unlocked version firmware on my T-Mobile galaxy S10.
[Samsung Galaxy S10 Guides, News, & Discussion] StoneyJSG:
The link to U1 firmware is in the OP.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
I only upload versions that I get early access to. Since the latest version can be obtained by anyone at any time directly via SamFirm or Frija, that usually means that for each of my threads, I only upload the very first initial release version. After release, it's rare for me to get access to a U1 version before it hits SamFirm/Frija.

So the one that's linked in the OP is a very old version, and even if you wanted to use it, can only be flashed on a bootloader 1 device
[Samsung Galaxy S10 Guides, News, & Discussion] nj2079:

hi i have a samsung g973u sold by verizon.that goes perfectly with another sim from another country but only for a few minutes after which i ask for nck code.

if I give the phone a restart the story is repeated. I understood that it is coded with the software.

I spent a lot of money trying to unlock this phone in service. All the codes generated by the servers did not work. The phone goes perfectly a few minutes after I ask for network lock code.

if he is a good friend who can help us with some clean software or another solution?????

I understood that-The (VZW) phone is network unlocked by default. The type of lock that they use is a software lock that comes preloaded on their firmwares.

i need a clean firmware for this phone or...another solution
