It has a newer bootloader because you very recently did a software update to it, which updated it to 7 from 6.

You can find out when bootloader 7 is released for U1 firmware by checking Frija or SamFW.com
[Samsung Galaxy S10+ Guides, News, & Discussion] schwinn8:
You can also see the BL version in the CSC code for the download. For example, for 973U1, XAA you can see G973U1OYM6IVH1 for the 7/21/22 download file.

The 5th-from-last digit is "6"... which means it's a BL v6. If your phone is 7, you can't put this on the phone. I noticed that 973U versions do have BL7 here, so that's probably what you're stuck with. You'll just have to watch the downloads and see when a 7-version appears. Generally, updates happen monthly or quarterly for security updates... based on the history it looks like we're quarterly now (May and August were the last two... 3 months apart). So you may see one soon, and you can only hope it's BL7...

Update: The correct rom for my device was finnaly posted, and it flashed perfectly with the correct version of the bootloader. My S10 is network bloatware free and the failure to activate message is gone. Thanks again to those that offered help. Never would have gotten there without you!
[Samsung Galaxy S10+ Guides, News, & Discussion] bakerjw:
Good day, all. I came across this forum when I attempted to take my SM-G975U phone from Verizon to another provider that uses the AT&T network. I am suspecting that I need to update the FW on my phone which I can learn about online easily enough.

So the model number is SM-G975U.

One UI is 3.1 and Android 11.

Baseband version is G975USQS6GUI1 <- From what I ready, I think that the 6 is the boot loader version

Kernel version is 4.14.190-abG975USQs6GUI1

Build number is RP1A.200720.012.G975USQs6GUI1

Knox version 3.7

Knox API level 33

TIMA 4.1.0

DualDAR 1.3.0

Below are 2 firmwares that I found. If the boot loader is version 6 and cannot be upgraded to 7, then I believe that I would need to use the bottom FW. These are both SM-G975U1 XAA FW.

PDA G975U1UES7IVJ2

CSC G975U1OYM7IVJ2

PDA G975U1UEU6IVH1

CSC G975U1OYM6IVH1

I am just looking for a sanity check to make sure that I get the right FW.

Any guidance is greatly appreciated.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Yes, firmware can always be UPgraded. DOWNgrading is what is blocked. For example, you cannot go from 7 back to 6
[Samsung Galaxy S10+ Guides, News, & Discussion] bakerjw:
Well I got a good Odin download with a patch from this site. Great product and well worth supporting with a donation.

Updated my phone with the Android 12 FW listed above and am in the process of de-Googling the phone.

Only issue is that the Network Mode option is missing. Asking about that on another thread as all I have is LTE ATM..
[Samsung Galaxy S10+ Guides, News, & Discussion] bakerjw:
As always, it pays to research. I am new to the inner workings of cell phones FWs.

Apparently, ATT phones need their bloatware to enable a lot of features.

downloading a new ATT build from samfw.com

SM-G975U1 - ATT - G975U1UES7IVJ2
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
But U1 firmware doesn't have any bloatware...
[Samsung Galaxy S10+ Guides, News, & Discussion] bakerjw:
You are correct. I mistyped what I was thinking

From what I've been reading, ATT doesn't support non ATT IMEI phones regardless of SIM cards or FW versions.

I might just park my number and do without a phone.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Sure they do. Depends on model, original network, and software version though
[Samsung Galaxy S10+ Guides, News, & Discussion] bakerjw:
I GREATLY appreciate any replies, but am frustrated with this whole mess.

I have a G975U that was unlocked and worked fine on Verizon. I updated to G975U1UES7IVJ2 and have been struggling ever since. My MVNO has been zero help other than canned lines of setting up canned APN settings.

In theory, ATT sees a valid SIM card, a proper FW and says "Hey. Let's enable our settings" like enabling 4g. Or at least that is my understanding.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Pretty standard for MVNOs, unfortunately. You get what you pay for 🤷🏻‍♂️
[Samsung Galaxy S10+ Guides, News, & Discussion] Maestro232:
Greetings. I picked up an unlocked G975U[1] (not sure if it was U1...sorry!). It had an ATT splash screen. I have US Mobile, which is an MVNO on Verizon's Warp 5G network. Calls were fine, but I had no data. That's when I began researching and noticed the US Mobile APN settings were not there. I couldn't add them either. So I decided to go the flashing route. I got the latest U1 ROM using CSC VZW from Frija and flashed to Odin without incident. Splash screen is gone and data works, but APN is locked to VZWINTERNET, which I think is problematic. US Mobile has their own MMS servlet and APN.

Now that I am researching further, I am wondering if I should have (and should now just) flash the U1 with XAA instead of VZW. I'm guessing that would unlock the APN section and I can put anything in there? Will I really be losing anything? Is there a downside?

Help appreciated.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Might fix it, might not. You'll just have to try it and see.

No downside
[Samsung Galaxy S10+ Guides, News, & Discussion] Maestro232:
>> Is there a way to do a limited flash at this point that won't blow away my setup? Not a big deal, It just takes a couple hours to download software and set things up to my liking.

>> What is the actual difference between the U1 ROM w/ XAA vs VZW?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Smart Switch doesn't take hours.

But, if by "blow away my setup" you're referring to a factory reset, the phone won't wipe if you flash the exact same version and use HOME CSC. However I can't guarantee that your issue will be fixed unless you wipe
[Samsung Galaxy S10+ Guides, News, & Discussion] Maestro232:
I guess I'm wondering if I can just flash the CSC file via ODIN and not reflash the other files.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
You can flash just HOME CSC if you want but I doubt it'll fix anything
[Samsung Galaxy S10+ Guides, News, & Discussion] Maestro232:
I'll give that a shot. I wish I understood what the best thing to do is re:CSC given I'm on an MVNO with no CSC code.

Yes, there are many "beginner's guide to flashing" type of threads on XDA. No it doesn't void the warranty. And no, it doesn't need to be SIM unlocked
[Samsung Galaxy S10+ Guides, News, & Discussion] :
Thank you. And if you don't mind, can you link a tutorial that lines up with your resources here? I've been trying to get AT&T to unlock my phone, but they keep denying the request because of errors in their system and I'm tired of dealing with their lackluster customer service
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Well then it's lucky that you found the thread! You can PM me for a solution on the SIM unlock if you want.

And I don't have links to any tutorials at hand, but there should be one in pretty much every "guides" section of almost every Samsung phone. Can probably find tons of info just by doing a Google search for it too
[Samsung Galaxy S10+ Guides, News, & Discussion] TechSilver13:

To fix this u need IMEI of a recent ATT branded phone. I used the IMEI from my ATT U s8+ to get all the features working on my unlocked s9+ u1 phone i bought from samsung. I called and said my (insert features here) arent working. They asked if it was an ATT phone, i said yes it was an ATT branded phone (fib) i bought from Samsung. I said it had an ATT logo on the back and ATT boot animation. I told the agent i read in some forums that this is a common issue, that ATT was working on a fix. That in the mean time the forums said the fix is to use the IMEI of your previous ATT branded phone to "provision or something" your new phone. They did it for me 3 or 4 times since i kept switching back and forth between builds. It didn't bother my s8+. I broke my s9 and went back to the 8 without issues. Called them again when my insurance replacement s9 got here.

ATT variant sm-g975u build number ending in SAT, trying to flash over to CHA (spectrum mobile firmware) with spectrum sim card. Ive appropriately placed the bl, ap, cp, and non home csc, and the CHA userdata using odin V3.13 3b patch.

I'm also trying to flash my ATT variant over to tmobile. I flashed to U1, but when I try to flash to T-Mobile it boots with the att logo and asks for an unlock code. Anyone have a quick rundown? I'm new to this and do appreciate any help
[Samsung Galaxy S10+ Guides, News, & Discussion] Jomino:
So if what vcdx said is true, do we actually need the AT&T userdata file if all we want to do is update to SAB without doing a factory reset and losing carrier bloat? Thanks in advance!
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Well first of all, an ATT phone is not going to work on a different carrier without being SIM unlocked. So that needs to be done first. Then you can convert firmware - and the steps for doing so were given earlier in the thread

No, you don't need to flash USERDATA if you're doing an Odin update instead of an OTA

Just FYI I have been using this fine for a while now on my Verizon S10+ but when traveling overseas it wouldnt let me use another sim card during my travels. It kept asking for a SIM unlock code and to call Verizon to get it. They had no idea why as it should of been unlocked. I used ODIN to flash the Verizon official firmware and the overseas SIM worked fine after that

is this will unlocked network on device ?? i have samsung s10 plus sprint try to unlocked it
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
No, simply flashing firmware will not unlock it. It's much more complicated and difficult than that. You need to find a business that offers the unlocking service
[Samsung Galaxy S10+ Guides, News, & Discussion] nugzo:
i found a new update while looking through Samsung firmware science. Anyone familiar with this ?

Information about your update

This firmware will update your S10+

from version G975USQU1ASBA

to version G975USQU1ASD3.

The file size is approximately 536.1 MB and the firmware was found on April 3, 2019.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
The D in the build number means that the firmware was created/compiled in April. It takes them about a month to decide on what the official next build will be, to fully test it, to approve it, and to begin rolling it out. Firmwares (for all sorts of models) ending in SCx are just now beginning to roll out, and the C means that it was created/compiled in March. So we won't see any SDx updates actually rolling out until the end of this month or the beginning of May
[Samsung Galaxy S10+ Guides, News, & Discussion] nugzo:
Thanks for the info. It made a huge difference with the fingerprint sensor for me. Sooo much better. I deleted all the originals and re registered. Used very little pressure and it read almost every touch. unlocked 10 out of 10 after re registering. Seems the ultrasonic window got larger too. i moved around a little and it never told me i wasnt covering the sensor like before. I register both thumbs twice.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
So you're saying that you were actually able to download and install the update?
[Samsung Galaxy S10+ Guides, News, & Discussion] SkandaH:
Looks like so.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Nice! The one thing that I was going to say earlier was that maybe we'll get this one rolled out sooner since it's for whatever carriers still are on SBA, and who didn't get an SCx update
[Samsung Galaxy S10+ Guides, News, & Discussion] iKenta:
hi all

so im confused on what to download SBA or SAT.. i know that i have to flash 4 files into the 4slots inside odin using download mode..

I was U1( s10+ 1tb version straight from samsung.com unlocked version)

i already odin flashed it to ATT ( i put att sim in it before flashing )

now id like to switch to verizon

so put in the sim card first ( verizon )

factory reset phone, and get past hello/welcome/setup screen

turn phone off, put into download mode

now as far as odin goes.

just to be safe and ready , i downloaded SBA_1 G975U_SBA , and hte SAT 1. but i also downloaded the userdata for VZW under sat folder and SBA folder..

im just confused on what to unzip and what not to unzip and what is the difference? im sorry if this been answered before i just dont want to brick my device .

---------- Post added at 04:53 AM ---------- Previous post was at 04:52 AM ----------

also is one of them the one where in future i just pop in a sim card of whatever carrier and the phone just auto program/restarts into that carrier/boot logo with all features and stuff or thats not til way later? lol
[Samsung Galaxy S10+ Guides, News, & Discussion] SkandaH:
Indeed! Looks like the unlocked US version will entirely skip ASCx builds.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
If you already flashed to AT&T firmware, then you already know how to do it. You just need to choose which of the 2 builds you want to be on. And if you want to have carrier bloat and features, then you need to be on U firmware
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Not necessarily. The U1 model could still get an SCx update later this month
[Samsung Galaxy S10+ Guides, News, & Discussion] iKenta:
SO , well first thanks for replying so fast!

so dont mess with SAT? download the SBA 3.5gb file. and the VZW sba userdata. and flash those 5 files ? ( minus the HOME CSC) ?

---------- Post added at 05:03 AM ---------- Previous post was at 05:02 AM ----------

just the sat and sba .. i dont understand the difference.. i dont mind the bloatware.. i actually would like to be with bloatware/official so i can receive verizon updates later as well.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
If you want SAT, flash SAT. If you want SBA, flash SBA. Lol.

Idk what the specific differences are. But I'm sure Samsung has the changelog posted somewhere

EVERYTHING went smooth. and pass pass. i did sba.. but for some reason, the bootlogo(carrier) still AT&T for some reason.. and inside is still ATT lol

i downloaded the 3gb+ file SBA

and the user data for VZW .. flashed all 5 files. the phone still AT&T . any ideas?

---------- Post added at 05:32 AM ---------- Previous post was at 05:30 AM ----------

i guess try the SAT now? i want my phone to be fully verizon.. no traces of ATT stuff. as if i bought the phone from VZW lol . my phone was originally U1 btw.

I flashed the U SBA build on my G975U1 with TMB Userdata. My CSC is still XAA/XAA/XAA I guess because I'm using a Telcel SIM card in Mexico. My build did change to U, instead of U1, and I was able to update to the new U SDA build update. I guess I'll keep it this way as there is no firmware difference to me and I can update to the carrier U updates that are available sooner than the unlocked.

For anyone that may want to know, VoLTE and WiFi Calling can be enabled by Telcel if you have a monthly subscription plan, not for prepaid lines. The Spam Protection (Smart Call) is not enabled either on the U1 or U firmwares.

Oh, and, SD3 is up on SamFirm for T-Mobile and Metro. Anyone can flash it, but you won't get OTAs after that if your carrier doesn't get the SD3 update, so you'd have to either manually flash the next update, or flash back to a build from your carrier in order to get OTAs

Haven't flash for a while.

I'm on sprint G975U ( ASC8) so if I wanted to flash a VZ firmware w/ bloatware what would be those steps be again? The only reason I'm doing this is because this is my 3rd s10+ replacement since I'm having the connectivity lte issue known on sprint.
