[UK] Unlocked S7 Edge - Enable EE features?

Hi folks,
So as in iPhone user, i've been following the latest Galaxy very closely and decided to take the plunge on Sunday!
Suffice to say, sat in front of me at the moment is my first Samsung (I went for the Edge).
I'm on EE, so i'd like to know how I go about enabling Wi-Fi calling (and VoLTE when it launches - although i'm aware it's testing in several areas at the moment) on my device. I bought it unlocked, direct from Samsung - which probably explains why I can't see the settings for it?
I've ready that I may have to flash the firmware with the EE version to get the features - my concern with that though is tripping Knox, as i'd like to use Samsung Pay when it launches.
Is there a method of enabling the features without flashing the firmware?
Any help on this would be greatly appreciated!

i wouldnt if i were you. i tried that with apple pay in australia and it didnt work. its region locked. wait for the official launch.
for me, my ban offers nfc payments through the phone so i can wait abit for samsung pay to arrive in australia and if im lucky, they will give out free stuff like in america.
i never tried volte calling. but you can always use whats app and stuff.

Its safe to do so,
I bought my S7 Edge from the Samsung store, and flashed the EE firmware, it doesn't trip knox, only custom changes will trip knox, So rooting/custom recoveries and such. its safe to flash the EE firmware. and WI-FI calling working for me, (How to enable WiFI calling). as we speak. But I did do a factory reset(delete everything) after flashing to make sure the CSC for EE was installing correctly.

Ah - just what I wanted to hear
Can you tell me if the EE firmware comes with loads of bloat? Also, will OTA updates work, or will I have to manually flash them when released (I'm sure I read that auto-updates don't work if flashing a different firmware - although I could have misconstrued that).
Thanks

Auto-update will work, but you will have to wait for EE to push the updates out. so might be a delay until they release them, Only difference from buying the phone from EE or Samsung is the firmware, So if you flash the whole phone and factory reset in recovery, its pretty much a EE phone. be warned sometimes WiFi calling will not work until you call up EE and ask them to activate it on your handset, (and that can be a funny conversation, since you didn't buy the phone from them but I managed to talk my way around it on my S6 edge+), And on my S7 Edge it seems to already be enabled after I flashed the EE firmware and enabled in the phone settings.

It's a shame that we still have to install carrier specific firmware to access these things. I thought I heard samsung had overcome this?
Some articles suggested that the S7 could install carrier specific software upon detection of SIM accordingly. This doesn't appear to be the case. I have just had to flash H3G firmware. BTW op it didn't trip KNOX

It is a bit rubbish really - it's one good thing Apple has over android imho. I know Google are trying to go down the same route with Carrier Updates - but they're gonna have to grow a pair if they're going to get anywhere with it.
Anyway, thanks kossiewossie - just finished flashing mine. Hoping I haven't tripped Knox (not checked yet, it's restoring my Google Account backup).

To flash the firmware is it just a case of downloading the EE firmware from sammobile and using Odin to flash it? Because I know for the S6 there was an issue where the partitions were different between the EE version and the unlocked version meaning you had to get hold of a PIT file to flash the EE firmware. Is that still the case?

I'm also considering doing the same. I'm on EE but it came through a re-seller so I've got stock Samsung firmware.
Other than the delay in updates being released, is there any other reason why not to do this? Are you able to flash back the BTU version if you grow tired of waiting for carrier updates and don't end up making the use of wifi calling?

The only benefit I see with the EE firmware is Wifi calling, but as I am in a fantastic reception area, I do not need it. Therefore I see no other reason to use the EE firmware and prefer updates as soon as they are released.
Yes, if you grow tired of waiting for carrier updates, you can flash back to BTE/XEU firmware.

I can't speak for EVR firmware. I used Samfirm to download 4 file H3G firmware and I was not asked for a PIT file.
Interesting there are PIT files included in the files if you unpack them so maybe this was used?

Having downloaded the EE firmware I'm a little confused with Odin.
I have:
AP...
BL...
CP...
CSC_EVR...
Home_CSC_EVR...
Do I need to select all of these within Odin? If so, which CSC as there seems to be two? Sorry if this is a stupid question....

When I did it last night, within Odin I selected files for AP, BL, CP and for CSC - CSC_EVR. I didn't use the Home_CSC_EVR file.
Knowing my luck, i've probably done it wrong - although my phone does seem to be running fine!!

I'm too cautious about flashing the wrong one lol. I'll wait until we know the difference I think!
Edit: Flashed it with the standard CSC. All seems well.

I flashed the standard csc myself and all seems well for over a day now. Would still like to know what the home csc file is for.
Edit. Just found out that home_csc doesn't contain the pit file so it doesn't wipe the phone. So would have to use the standard CSC when changing firmware.

Have a SM-G930V. Want to flash but have no idea what to do.

Hey there, hope y'all are doing well.
I recently purchased a Samsung Galaxy S7 SM-G930V, Nougat 7.0 (note: I live in europe, and it's an unlocked phone). I want to get rid of Verizon logo while booting and all the unnecessary apps connected with Verizon. Plus, as you know Verizon locks some functions like the device maintenance, turning off the backlight of the capacitive buttons, etc, etc.
So, I'd like to have a clean/untouched samsung firmware without any useless apps.
Is androidfilehost.com trustworthy? what about updato.com? (the latter had slow dl speed, and I stumbled upon the first alternative)
PS. by the way, mine reads G930VVRS4BQI1, so one thing that confused me was while loking up for files to download; should I get the G930VVRS4BQI1 which may be the only compatible file for my phone, or do I already have G930VVRS4BQI1, so downloading it would be useless?
Since I wouldn't like to tinker often with the phone system, what do you suggest, flashing or rooting?
Is there any guide for my case for flashing?
I noticed these two on the front page:

which should I pick?
and since the posts were last edited in may and september, where can I find the latest firmware?
and after doing all this, will everything work well, will I get OTA updates?
I would really appreciate someone helping me out, whenever you're free.
Thanks in advance

You can actually cross flash any Qualcomm s7 firmware between all carrier handsets. With your case being in Europe I would recommend the sm-G930U firmware. Which is the carrier unlocked variant of the S7 stateside that has all bands unlocked that the modem is capable of. You will recieve OTA's. It's Odin files are on Updato and SamMobile. AndroidHost is trustworthy.
In your case of not wanting to tinker or have a "need to have" rooted feature on the new device, I would flash the the 930U firmware and enjoy your new non branded system.

Hey JediDru,
I also just bought the S7 Verizon variant, and am planning on using it on MetroPCS. Would you recommend the 930U firmware for me as well? I wouldn't mind getting rid of the Verizon bloat before I hand it over to my wife...

You very well could. I think there is a thread around here specifically about metropcs setup somewhere between the verizon s7 and tmobile s7 forums. I use my 930v flashed to 930U on tmobile.

hey there, thanks for your advice! I downloaded the latest file from here. sammobile"dot"com/firmwares/galaxy-s7/SM-G930U/VZW/
In a moment I was clueless at the "pick country" since there were more than one USA options. so I went with verizon, since my phone comes from verizon.
In the link I mentioned above it reads this This is for SM-G930U from USA (Verizon) which makes no sense to me, how it can be both "U"-unlocked and verizon at the same time... but, oh well, I flashed it 4 days ago and I've encountered no problem, which is all that matters! Hope I made no mistake at picking that file.

Recently purchased galaxy S7 SMG-930V (Best buy version) from a private owner.
I am on cricket and on APN setup LTE and MMS works without issues. Only issue is that upon dialing USSD code i get 'Connection problem or Invalid MMI code' . I tried all options available mentioned in this forum still doesn't work. Which version of SM-G930U should i flash? Main reason i purchased the phone is for Samusing Pay. Don't want to brick or lose Samusing Pay option after flash.
Inputs are appreciated.

Yes Flashing the G930U firmware removes all carrier bloat.
Samsung pay comes with the U firmware.
The last time I was on the U I had bad standby drain. I read somewhere else it has to do with the U not dozing correctly. They may very well have fixed it now, I'm on the latest tmobile 4BRA firmware and it sleeps like a baby right now.

Flashed the verizon U firmware and it did remove all the bloatware. Still need to check on battery drain with Samsung Pay. All other apps are in "Always Sleeping Apps" for better battery performance.
For future reference make sure before flashing new firmware google accounts and lock screen securities are removed/disabled.
Is there a way to back up apps with user data and home screen and reuse instead of installing all over again when a new firmaware is flashed. Spoiled by the root and titanium full back. That was so easy.

As far as I know, no. It's not so bad. I had gotten into the habit of taking screen shots of my app drawer and redownloading. To think now I can just redownload the configuration of apps I had before is as good as it gets. I still just redownload. I like to re-set everything back up just so I know its done.

I haven't tried this method but to backup and restore all installed apps check this Link.

Actually, if all you want to do is switch carriers (same GMail address), then a firmware swap will work.
I have an ex-Verizon (blacklisted IMEI - previous owner)S7 that I was moving to Tracfone (which uses both VZW and T-Mobile towers) - naturally, VZW was a non-starter; however, the UnCarrier was fine, so I used a T-Mobile nanoSIM (Tracfone triple-punch SIM kit includes SIMs from all except Sprint) and replaced the VZW firmware with T-M firmware (Prince Comsy ODIN does the track rather neatly). As long as your IMEI is not blacklisted from the TARGET, such a swap will always work.

S10+ Appears To Be Incapable of Software Updates After Switching Carriers

Hi all,
I have an S10+ that refuses to acknowledge that its software is out of date.
I bought a US Cellular Galaxy S10+ from the Samsung website when the phones launched in March 2019. In late August 2019, I decided to switch to AT&T (had previously been on my parents' plan, wanted to start my own). I transferred the phone and my number over to AT&T.
Recently, I noticed that I have not received a software update or security update since before I switched. My Android version is still 9, my kernel is dated Aug 7, 2019, and my security patch level is Aug 1, 2019.
No matter what I do, my phone says its software is up to date.
I took the following actions:
Called AT&T to have them update the phone in their servers or whatever it is they do.
Changed the date in the phone, restarted and searched for updates.
Cleared the cache data in the phone's BIOS.
Tried using Smart Switch, it said it was up to date.
Did a factory reset of my phone.
Contacted Samsung, was told to talk to my carrier.
Called AT&T again, was told they could not push the updates because the IMEI number is for a US Cellular phone, not an AT&T phone.
Today, I took it to a Samsung representative at a local Best Buy. He plugged the phone in to whatever PC tool he has, it prompted him to download the latest AT&T firmware. He did so and tried flashing the phone. I looked and saw the blue BIOS screen where the phone said it was downloading the firmware. However, when it finished and he started the phone up again, the phone's software information was unchanged. He tried it a second time, and still no change. He told me he had never seen a phone refuse the firmware like this, and he said there was nothing he else he could think of to try. He said even if I could flash the firmware, it might still refuse to receive updates and I'd have to keep flashing it to get all the updates. His suggestion was to just wait and try to see if I could get a deal on an S20.
This phone is paid off, and still in great condition. I'd really rather not have to replace it less than a year after I got it. I've thought about trying to flash the phone myself with Odin, but I'm not sure whether I need to try it with AT&T firmware or US Cellular firmware. Furthermore, I can't find AT&T firmware for the SM-G975U, only the SM-G975U1, and I'm not even sure if it's up to date. What are your suggestions?

You could try updating using the Frija & Odin method found in News & Discussion board, then see if next month you receive OTA?

What does it show for you over there?
Your phone is probably still on the US Cellular CSC.
I'd recommend flashing the G975U1 ATT firmware if you want ATT features, or the XAA firmware, to convert your device to a completely unbranded variant with no carrier apps.
You can use SamFirm or Frija to get the firmwares.
Use 'SM-G975U1' as the model and for the CSC, use 'ATT' if you want the AT&T firmware, or 'XAA' if you want the unbranded firmware.
Flash it with patched Odin here:
https://androidfilehost.com/?fid=6006931924117912211
You will have to wipe/reset the entire phone with this process, so make sure to use Smart Switch to backup your data.

Hey, thanks for the advice.
My service provider software information version is:
SAOMC_SM-G975U_OYN_ATT_PP_0039
R58M20FYAKW
ATT/ATT/USC
I've looked at both Frija and SamFirm/Updato. Frija doesn't seem to recognize ATT or OYN as a CSC for me when I try using it in the auto search for either SM-G975U or SM-G975U1. Updato has an AT&T firmware, but it's from Nov 2019 and is still Android 9. SamMobile claims to have more up to date firmware, but their download links always send me to the registration page, even after I already registered (I'm guessing they're not as free as they claim to be).

Ah, it seems like your device has switched to the ATT CSC but remained on a US cellular build, resulting in there being no available update file on the ATT server.
Download the XAA unbranded G975U1 firmware with Frija.
I completely forgot that ATT doesn't host their firmware files on Samsung servers, instead it uses its own servers for updates.
Updato and SamMobile are both greedy and want you to pay for uncapped download speeds so I wouldn't recommend using them.

With patched Odin can change the csc? I have G977B and cannot change the csc.

Only applies to US variants when switching from G975U to G975U1.
It's 'patched' as it bypasses the model number check.

Thank you.

It took me forever to find someone with this problem / solution.
I switched from Verizon to Xfinity Mobile and had not received a security patch since Oct '21 and was still on Android 11.
You'd think that this problem occurs often enough that support would know the solution.
Xfinity Mobile told me Samsung was responsible.
Samsung (Best Buy Geek Squad who is certified Samsung Service Center) said Xfinity Mobile is responsible but gave me the idea that the phone might be 'stuck' on Verizon so it can't pull the updates from Xfinity Mobile.
The build was from Verizon.
I installed the latest build from Xfinity Mobile (CHA) for this model phone (SM-G973U) so it now has Android 12 with Dec '22 security patch.
I'm guessing that the updates will work now but I won't find out for 3 months since the S10 is now on quarterly releases.
Thanks 2x.

G988U and G988U1 Firmware Links and Flashing Discussion Here

For those who aren't already aware, G988U is the model number of all of the US carrier versions of the S20 Ultra. The G988U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit SamFirm/Frija, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model - so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit SamFirm/Frija.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware, I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!
U firmware: https://www.androidfilehost.com/?w=files&flid=305574
U1 firmware: https://www.androidfilehost.com/?w=files&flid=305575
Notes:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have lots of threads just like this one for other Samsung flagships, if it interests you. For those who have already made use of my previous threads for a different device and are upgrading to an S20, welcome back
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- My naming method for folders on AFH is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data
- Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
- For identifying USERDATAS, and to know what region/CSC to use in SamFirm/Frija:
ATT = AT&T (not available via SamFirm/Frija)
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
USC = US Cellular
VZW = Verizon (available via SamFirm/Frija, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want

Pre-release notes:
1. I do not have one of these and do not plan to acquire one, so I have no idea if anything can actually be flashed at this moment - I'm just providing the firmware. Like all other models, I'm assuming patched Odin is needed for this, but it wouldn't surprise me if a new version is needed for this specific device. There's only one way to know though, so as soon as someone gets their hands on one and can try this, please let us know.
2. I don't know if using the HOME CSC will actually save data. I don't get access to that file straight from the source - I have to decompile the regular CSC, remove the parts that initiate the factory reset, and then re-compile it. Based on the S10 and Note 10, I've done what I think will avoid a factory reset. But the S20 has some new partitions, so we won't know for sure until someone tests it. So if you're willing to be that guinea pig, you're responsible for taking proper steps to avoid an FRP lock, make sure your data is backed up, etc

I will be the first to try. I ordered the unlocked. I will flash the TMO firmware. I have it downloaded already

Thanks for posting these! I ordered the Verizon model but am planning on flashing the unlocked firmware once I get it in hand.

at this point can we only flash the Userdata for the carrier without the actual firmware?

I guess you could flash USERDATA by itself. There's really no point to doing that though

No the firmware is there. Its a separate file zipped up

Canadian firmware has been able to be flashed to US Samsung flagship phones ever since the S7. So yes, I would assume that that trend will continue with the S20

Samfirm and Frija have TBN firmware available...I assume based on the naming that it's newer than the ones you have uploaded? I also saw on Sammobile that Verizon has already released a newer firmware which is odd considering they haven't even shipped them yet...lol

1. SamFirm and Frija will always only give you whatever the newest/latest version is. So if it's not the same version that I have uploaded, then yes, it's a newer one.
2. Not odd at all. Most devices get an OTA before release to fix bugs, add features, etc. There was an OTA that came out shortly after I got access to the files, so TBN would be the 3rd release now for this model
3. Looks like firmware has now hit SamFirm and Frija for all S20 models, for anyone who wants to download it themselves

Tried flashing multiple times ATT FW with Odin 3.14.1. Odin reports no errors but it's definitely not taking. SW info still reports XAA and I have no "carrier bloat".

Its not as simple as that. There is a trick when going from unlocked to carrier fw. Look on s10 forums, the procedure is there I believe

Ive been there done that. Timing is everything. Gotta reset dorectly after boot and flash and when i see carrier update prompt-you know its right. Trial and error.

TY. Tried again this morning and got it. I assumed I did not need to flash U1 first since my phone was already unlocked. Doing that made all the difference. New to all of this but glad it's finally done!

My other threads are chock full of discussions of this exact thing. Bottom line is, we don't know until someone tries it

I'm trying to download the Tmobile from the SamFirm tool for my S20 ultra SM-G988U1
I put in the model number above and TMB in the region.
But I also noticed that if I enter any other region, it's the same filename and size as well. Just want to make sure about downloading the right file.
I re-read the OP, and saw some youtube videos. It's my assumption now that I need to put SM-G988U in the MODEL and keep TMB as the region to download the correct firmware. Am I correct in assuming this is the correct way to go?
The reason I want to do this is because I want to have Tmobiles advance messaging feature back

G986U and G986U1 Firmware Links and Flashing Discussion Here

For those who aren't already aware, G986U is the model number of all of the US carrier versions of the S20+. The G986U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit SamFirm/Frija, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model - so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit SamFirm/Frija.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!
U firmware: https://www.androidfilehost.com/?w=files&flid=305579
U1 firmware: https://www.androidfilehost.com/?w=files&flid=305580
Notes:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have lots of threads just like this one for other Samsung flagships, if it interests you. For those who have already made use of my previous threads for a different device and are upgrading to an S20, welcome back
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- My naming method for folders on AFH is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data.
- Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
- For identifying USERDATAS, and to know what region/CSC to use in SamFirm/Frija:
AIO = Cricket (not available via SamFirm/Frija)
ATT = AT&T (not available via SamFirm/Frija)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon (available via SamFirm/Frija, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it

Yes, if by "stock" you mean "factory unlocked" aka U1.

It has been a while since i looked into flashing. I want to do the same (have an s20+ verizon) I want factory unlocked software . On sam mobile , everything looks like it has a carrier attached even looking up U1 model. Which did you pick?

The one from Sammobile is more current, there was an update soon after launch. You can compare the build number to that of the software on your phone.

If you didn't follow the steps in the OP correctly, then yes, you can very possibly end up with the same bloat as before

Ok. So I guess the one place I'm struggling, from a not implemented, but understanding standpoint is that the instructions show how to go to carrier branded versions, but if I just want the U1 firmware, do I need to follow through with the other portion, the second flashing that happens, or can I just run the unbranded one?

Just flash U1 - nothing else

Thank you for this. I was able to flash from Tmobile to the U1 firmware with a virtual machine.
