[HELP] G950U confusion - Samsung Galaxy S8 Questions and Answers

I recently bought a used S8 from a friend, it's all great and I am liking it so far but I wanted to root it and install a custom rom on it, or flash the stock One UI rom at least.
So I was looking around and see which carrier phone it is, since I am not in US so it didn't matter to me
I went into Download Mode and the carrier there says TMB but if I search the baseband version (G950USQS5CRF5) on the google, it says its Verizon, so I am confused that which carrier version is my phone exactly.
and can I just flash the stock One UI rom (for TMobile) ignoring the version that I have.
Sorry if I posted in the wrong section.

So can I just download the official Pie rom that is for TMobile and install it?
Or do I have to use this method that you sent before flashing any rom even if its stock?

No put your tmobile sim in and it should auto select its own csc which is for carrier selection and reboot. If not download the latest firmware from sammobile and select the tmobile one and flash.
These devices are awesome at selecting on their own. My wife's rebooted and installed verizons csc all on it's own
Should be a screen says new sim inserted please restart to use

Install T-mobile firmware on internation

Is there anyway that I can install T-mobile firmware on my N9005 Galaxy Note 3? I tried to do it but it fails everytime. is there any way I can change my model number or something so I can install different firmwares from different variants? I ask this because I used to own a HTC One and I was able to change the model number so I could install different firmwares.

The better question is you have an international model so what is your goal? Are you trying to install a specific ROM to enable features (like modem frequencies) which have been disabled? You cannot install another model ROM on your device or you will just go into a boot loop or soft-brick your device and you will need to go through a recovery process. I'm going to assume you want to install a ROM for a specific feature or set of features which can be done but you simply need to ROOT and find a compatible ROM with the features you require.
Hope this helps!

yeah I was going to see if I would get LTE speeds if I'd installed the t-mobile firmware. also I want to be able to use Wifi calling as well. but the main reason I wanted to try out t-mobile firmware was, so I could get LTE speeds.

[Q] Carrier Firmware

I recently re-installed the stock firmware on my Galaxy S4, because I wanted to get the newest version, which I previously couldn't as I was rooted. And I noticed when It booted, it now has a Carrier logo of THREE on the boot screen. Was this added in 4.4.2? I could only find carrier versions of the firmware online, and no others, so I picked my carrier. If there is any online that are not linked to a carrier could I get a link please?
GT-I9505 - Is the model

yeah of course, all you gotta do is download the correct firmware through sammobile.com. just select your country with no carrier

1. Conect it to Kies 3 and verify your CSC like in pic attached below.
2. Knowing your CSC you can go to Sammobile.com and download the correct firmware for ur phone. The firmware will be without carrier logos if your phone is unlocked.
3. Tell me your CSC if u are confused and i will help telling you the correct firmware for ur device

Hello everyone
So i got AT&T note4 SM-N910A on a good deal about 135$ yesterday and its unlocked running on android 5.0.1 lollipop i just want to flash 6.0.1 marshmallow stock via ODIN but i afraid if i flash another stock rom it will get network locked and i know deep down so far this thing is not rootable. so please anyone know exactly is it safe to upgrade from 5.0.1 to 6.0.1 without messing anything up because its running a modified firmware with lot of languages included and all blotware/bootanimation/tethering hotspot unlocked etc from AT&T removed.
Here are some screenshots to help understand the device i got.
TIA
EDIT-I FLASHED STOCK 6.0.1 AND EVERYTHING WORKS FINE
Moderators feel free to delete the thread.

Thanks for replying
Yes indeed odin is harmless but my only concern was sim network lock because i have usa AT&T note 4 and i live outside usa .
previously i had sprint note 4 and i flashed stock via odin and it got network locked it was showing "invalid sim" but this doesn't happens with Tmobile/verizon/AT&T thankfully .
thats y i thought better to ask and take advice in xda.
Have a good day:good:

Now that you mention it, I did get that error on my T-Mobile Note 3 a while ago. I upgraded to the latest version via Odin (I also live outside the US) and the phone is unlocked, but I kept getting invalid T-Mobile SIM inserted and didn't get any data.
Fortunately, my plan wasn't to go back to stock, only to test GPS (Google Maps) on stock. After that, I went immediately to a custom ROM and did not get that error any more.
Hope you don't get it xD
Good day :good:

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
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
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
It's been confirmed that Odin 3.14.1 Patched is needed for flashing S20s - https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
H/T @clabern
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

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.

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?

How?
The 986W version isn't going to be released until Jan 5th so you can download the 986U version from this site and install it with ODIN. Don't do this if you don't understand how to use tools like this, especially if you like your phone...

Did you have to change your CSC? Did you pick HOME for your CSC during the download? I noticed the *#272*IMEI# method to change your CSC doesn't work on the NOTE 20. Regardless, I see my phone still sees 5G. CSC right now is OYN??

Sorry for the late reply. I found the Rogers CSC by googling "Rogers Note 20 ultra Rogers Stock firmware"
I downloaded the whole 6gb file, but only used the Home_CSC from Rogers and used it with ODIN after I got the ATT update.
Have had no issues at all, and One UI 3.0 is a blessing.
