U1 has not yet caught up to bootloader V2, so I would recommend first flashing a V1 U1, then a slightly older V1 TMO firmware also. This will allow you to make sure the phone works properly, but without being stuck on V2 firmware in the event it does not.

Grab the latest U1 and TMO firmware I have in Post #2. Sorry it's a bit outdated, but that's a good thing in this case. Once you convert to U1 and it works, then flash the TMO firmware and be sure the use the non-Home CSC to wipe the phone. If all still goes well after, you can either take OTAs to get up to the newest release, or flash a newer firmware through Odin.

Awesome! Thanks so much for the help. I'm having to send my S10+ back in for a replacement with the seller because the boot-loop issue is not going away, but I'll keep this in mind when I receive the new one.

Is there a disadvantage to using Bootloader V2? Or is it simply because it just came out so I would be very restricted in terms of the firmwares I can use?
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Bootloaders can't be downgraded, so once on V2, you can only flash V2 firmware, which is not out for U1 yet.

sm-g975f/ds firmware

New to flashing so please forgive me. I bought an unlocked sm-g975f from ebay. How do I flash north American tmobile firmware to get band 71 access and other features I wouldn't get otherwise? Thanks so much for your help
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
You cannot. The F models are Exynos chipsets and do not support US firmware.
[Samsung Galaxy S10+ Guides, News, & Discussion] Pokernoob:

[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
I can't say for certain myself, but other phones like the OnePlus 7 Pro on International firmware support TMO WiFi Calling.

[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Follow the steps at the bottom of the quoted post to convert from one carrier to another. You need the regular CSC file or else it won't wipe, which is required for converting.

[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
You don't. You can't flash Qualcomm firmware to a Exynos device.

But according to the spec sheet, that model doesn't have band 71 anyways. And that's a hardware issue - not a software one
[Samsung Galaxy S10+ Guides, News, & Discussion] todd3835:
Only if your still on a v1 bootloader. Part of the process is flashing to U1. There's no V2 bootloader for U1 yet.

If your still on V1 I'd do it right away before you get an Ota to V2 and are stuck until the next U1 is out.
[Samsung Galaxy S10+ Guides, News, & Discussion] Exaxoid:

[Samsung Galaxy S10+ Guides, News, & Discussion] Pokernoob:
Band 71

So I ended up buying an unlocked by Samsung sm-g975uzwaxaa on prime day sale. Will I need to flash TMO firmware to get band 71 to work? I see it has the band built in but not sure if it will light up when I just insert my TMO sim. Thanks for the help
[Samsung Galaxy S10+ Guides, News, & Discussion] AestenD:
I don't think the Sprint version of this firmware round is out yet, just Tmo and Verizon. Couple of the other small carriers.

Possibility, but I kinda doubt it. Usually it's things like Wifi calling or volte type stuff that needs the carrier specific.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Yes. You can always flash any U or U1 version. But remember that there is no Bootloader 2 firmware for U1, so if you flash SF6, you have to wait for the next U1 version if you want to go back

Depends on which firmware comes loaded, and whether it automatically converts to T-Mo bloat when you insert your SIM. If you don't get it right out of the box and it doesn't do the conversion, then yes, you'll probably need to flash. I don't think any other carriers use 71, so their firmware might not support it. Or you could do U1 - I think all bands are enabled then.
[Samsung Galaxy S10+ Guides, News, & Discussion] jhs39:
That's the US unlocked version so you shouldn't have any problems with band 71, WiFi Calling or Volte on the T-Mobile network out of the box. But since it's not going to have T-Mobile specific firmware you might need to manually download any T-Mobile apps you use like their visual voicemail app.

You will also probably receive OTAs from Samsung rather than T-Mobile unless you choose to flash the T-Mobile branded firmware.
[Samsung Galaxy S10+ Guides, News, & Discussion] Pokernoob:
That's good news thanks for the info. I only care about the wifi calling, volte and band 71 so should be a good shape. Do you happen to know if this phone would also work on Verizon if I popped a Verizon sim in it?
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Yep. All US Snapdragon models are identical from a hardware perspective. You just need to have matching firmware for some features, depending on the carrier, and be SIM unlocked. You're good on the last part since it was purchased without a carrier.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
The model number was listed as U, not U1. So unless the 1 was accidentally left out, no, it's not the US unlocked version
[Samsung Galaxy S10+ Guides, News, & Discussion] jhs39:
You are talking about the firmware. The AISN number is what is listed on Amazon. That's the AISN number for the US unlocked version.

I just wanted to say THANK YOU for posting this! I was able to take an AT&T G975U, flash it to U1, then over to Verizon yesterday, and now I have FULL functionality with Verizon! Wi-Fi Calling works, Visual Voicemail works, Video Calling works, and almost all of their bloatware was able to be uninstalled entirely without having to disable the apps! Again, THANK YOU!
[Samsung Galaxy S10+ Guides, News, & Discussion] iKenta:
so i downloaded the U1 files for (unlocked) because my phone was originally unlocked, and i switched from that to verizon/tmobile etc etc.. but for some odd reason, i put in a 'simple mobile' sim card and the phone magically changed it to self to MetroPCs (boot starter image etc) you know.. how the Note9/8 and S8/9 does when you insert any carrier sim card and it auto change to that carrier..

so i tried inserting verizon sim hoping it'll change back to verizon but nothing.. its stuck there and i tried uploading the BL/AP/CP/CSC files for it to go back to its original form of "unlocked version" how i got it from samsung.. but i keep getting this error below, i even tried regular CSC and the HOME as well but no dice... anyone got any insight on that?

thanks in advance.

If you flashed U firmware over U1, and the U firmware is bootloader V2, you will be stuck on it until U1 is updated to V2.

I have a question I recently left at&t for verizon and unlocked my galaxy s10+ and I plan on flashing the the unlocked firmware. Is there a difference between the unlocked firmware and verizon specific firmware. One last thing, since this phone is now sim unlocked can it be rooted?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
If you mean that OTA updates aren't working properly, then you could also download the OTA zip to the phone and install via Recovery

1. Yes, there are many differences between U firmware and U1.

2. Whether a device is SIM unlocked has no bearing on its ability to be rooted
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
You will need VZW U firmware for full functionality. Only the Exynos variants of the current Galaxy models can be rooted. No carrier or unlocked phone sold in the US by Samsung or carriers can be rooted.
[Samsung Galaxy S10+ Guides, News, & Discussion] bigvic5bn:
Thank you, I used an unlock code and it unlocked with my Verizon sim card. So now just flash the verizon firmware? I just don't want to miss anything if I go the non verizon route. Right now I'm not getting my messaging and I could be wrong but is it because the messages app was an at&t feature or advanced messaging or whatever its called. I downloaded verizon messages and half of them still don't come through. I'm leaning towards unlocked firmware but again I don't want to miss anything.

[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Messaging issues are frequent when mixing firmware. If you flash U1 firmware, you will get all your messages, but miss out on RCS features with other VZW users (larger pictures, videos, typing indicators). If you live in an area with decent VZW coverage, you won't need WiFi Calling, which is one of the main reasons to have U firmware. U1 will also give you access to Samsung Cloud, which VZW removes in order to push their own cloud storage.
[Samsung Galaxy S10+ Guides, News, & Discussion] bigvic5bn:
Thanks for that. Ive become to dependent on Samsung cloud to not do away with it now. That answers that thanks again
[Samsung Galaxy S10+ Guides, News, & Discussion] jhs39:
You might not be able to flash the unlocked firmware if your AT&T firmware was up to date because the carrier firmware is on bootloader V2 and the unlocked firmware is still on bootloader V1.

If you can't flash the unlocked firmware (until it gets V2) you are better off flashing the Verizon firmware than leaving AT&T. I bought an unlocked AT&T S10+ and had problems with my T-Mobile service until I switched to the U1 firmware--there's stuff with the network, WiFi and messaging settings in the AT&T firmware that's customized for AT&T services.
[Samsung Galaxy S10+ Guides, News, & Discussion] bigvic5bn:
Your timing was perfect Odin just failed and then I realized why it wasn't working. I cant find a link to Verizon's V2 firmware that I can download. That's why I'm looking for at the moment with no luck. Suggestion?
[Samsung Galaxy S10+ Guides, News, & Discussion] hleo114312:
Not good explaining hope you get to understand. One ex. On the PDA info like on sammobile there will have a version G970FXXU3ASG8 like that one, the numer 3 is the 5th before last digit. That tells the bootloader version. And the s10+ U1 still is in V1 while the U model is already on V2 so you can only flash same bootloader versions on your phone until Samsung releases the v2 for the unlocked version.

[Samsung Galaxy S10+ Guides, News, & Discussion] jhs39:
Not sure where you can find the Verizon V2 firmware. Sorry. If it's not in the XDA thread with the other firmware downloads maybe an Odin flash able version hasn't been released.
[Samsung Galaxy S10+ Guides, News, & Discussion] jwarrior319:
Use the sammobile website and enter your model number(SM-G975U for + model or SM-G970U for regular model) and grab the newest VZW one.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
SamMobile is slower than dirt, unless you're paying for a premium subscription.

SamFirm is all you ever need for downloading firmware - unless you need AT&T or Cricket. Manual entry is required in order to find Verizon firmware however - the Auto option simply doesn't work for some reason

I have an SM-G975U1 and on ASDB. I found ASD8 for U1, and tried to install in recovery mode. But, it wouldn't install. Do I have to install using Odin?
[Samsung Galaxy S10+ Guides, News, & Discussion] jwarrior319:
ASD8 is the Build before ASDB
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Correct - Samsung abides by computerized alphabetical rules, which dictate that in an alphabetical list, numbers will come before letters. For example, if you have a bunch of folders on your computer and each is named either 1 number or 1 letter, the numbered ones will show first, if you tell the computer to alphabetize the list.

You can use SamMobile as a reference for which order the builds were released in - just look at the dates. But also keep in mind that the updated version will probably only install via Recovery if that version was actually released for the carrier/region firmware that you're on. Not all carriers/regions get all versions. For example, SPR region got SD5 instead of SD3 like the other carriers. So if you're already on SPR, and try to install a zip in Recovery to upgrade to SD3, it'll probably fail.

Odin, on the other hand, can be used to install any version on any phone, no matter what version or region it's currently on - assuming that you're not trying to downgrade bootloaders
[Samsung Galaxy S10+ Guides, News, & Discussion] wooderson73:

I apologize if I am wrong, but I didn't, and still don't see anything about flashing the userdata with the rest of the files

If you are trying to convert from one carrier to another, you MUST flash in the order shown below

Flash U1 Unbranded firmware

Factory reset in recovery

Allow phone to fully boot to Android

Go through the setup menu, but you do not need to sign in or restore any data

Flash other carrier firmware in Odin - be sure to use regular CSC file

Factory reset in recovery

You should now see the splash screen that matches your SIM

I recently switched to US Cellular to trial them in my area. I went to U1 unlocked, put in the sim, and flashed to at&t like is suggested since they said at&t was the most compatible, but I got forced into the v2 bootloader with the ASF6 update, since samsung forces it down your throat after three postpones. Today, I got ASG8. Is US Cellular pushing their own updates? I don't see AT&T having ASG8 yet, even though I started with their firmware.

In any event, I'm probably going back to Wing with an AT&T, I only hope reflashing a v2 bootloader firmware from AT&T works to remove the branding and let me set up the voicemail app again, since I can't go back to U1 until samsung gets off its ass and releases and update past the stale ASD8.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
1. I'm not sure why you would use AT&T firmware, if your provider is US Cellular. The most compatible firmware is either going to be that of the provider that you're using, or U1.

2. US Cellular is getting SG8, yes. So that's probably where your updates are coming from

3. Not sure what branding you're trying to remove, but the only way to remove carrier branding is by flashing U1
[Samsung Galaxy S10+ Guides, News, & Discussion] MadCabbit:
I used at&t when switching from U1 because as far as I know, there aren't any full odin files for us cellular that I can find, and us cellular said they were most compatible with at&t when it came to byod phones. The other reason is that the AT&T firmware files/userdata here actually have the US Cellular apps in them. I saw them when I was still using wing.

Even if I have to have the branding, I'd like to get the voicemail app working again. In the very least, like I said, I won't be able to flash U1 until Samsung stops being lazy and give me an update I can actually use.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
1. USC firmware can be gotten everywhere lol. SamFirm is the easiest and fastest way to get the latest version. You'd need to use SamMobile or something similar if you wanted an older version

2. Whichever USC employee told you that they're most compatible with AT&T phones is a moron. All Samsung flagships for the past 3 years are all universal models - they all have the exact same bands/frequencies etc. And even if they weren't, T-Mobile is also GSM so their phones would be equally compatible.

3. I promise you that no carrier's firmware has any other carrier's apps in them. If you go to an AT&T store, you're not going to find any USC apps on any of their display models. You also wouldn't find any T-Mobile apps on a Verizon phone, or any "X" carrier apps on any "Y" carrier's phone.
[Samsung Galaxy S10+ Guides, News, & Discussion] jwarrior319:
Sammobile does provide USC ( US Cellular) firmware. In my experience when using U1 firmware the ATT version doesn't play well with USC SIM's. Don't Know why, just my experience. I always used VZW firmware because its usually released faster. Its also worked perfectly with any SIM i installed. The only thing USC firmware will give you is their Bloatware file. When using VZW firmware even with their own Bloatware file, using another carrier removes that bloat and doesn't add theirs.
