Flashing unlocked to Tmobile firmware - Samsung Galaxy S10+ Questions & Answers

So I'm currently going crazy.
Have s10+ unlocked.
Baseband version: G975U1UEU2ASGB
SM-G975U1_9_004
I'm wanting to flash tmobile firmware to improve cell signal.
I've done some research and know I need to flash U firmware just not sure which one and if it has to be them same as the current firmware the phone has.
Can someone please provide step by step on what I would need to do as well as what firmware I would need to flash to achieve this.
I don't want to mess it up and then suddenly get stuck on boot.
Thanks in advance.

Head over to sammobile and follow the directions in this link. You will need the modified Odin from here. The sammobile link is the latest t-mobile firmware. If you ever want to go back to the u1 firmware that is located here as well.

Awesome thank you so much. I'll give it a go later today ?

Does anybody have a mirror or can you upload the latest tmobile firmware?
I've been trying to download for 4 days and at 92% the download just stops. Ive tried all sorts of different sites and nothing so far.

my experience is that samfirm works consistently while the others don't. Download the samfirm app then enter the model you want (SM-G975U). The region will be TMB for T-Mobile, and let it download the files and decrypt for you.

Try frija, I was losing my mind looking for it also, initially it didn't work but after installing c++ 8 something something it worked. Downloaded really fast also

I'm not able to find anything for T-Mobile USA in the latest version of this tool. Has anyone else been able to find it?

Need latest Bootloader & Modem 935W8 (canada) Variant (Please and Thank You)

As the titles says, I need the latest BL and Modem (or a link on where to get it) as I am going to install "OnTheEdge" 6.0 Beta 2 to try it out however I can't figure out how to download the BL and Modem for my specific variation and from my understanding due to canada the W8 is not compatible with the F international variation.
*Edit* - I should note I have already looked at "https://www.sammobile.com/firmwares/database/SM-G935W8/RWC/" however that only has for 6.0.1, I need the 7.0.0 correct?
*Edit 2* - Lets say I do just download the latest 6.0.1, its a large file from SamMobile, how do I get the BL and Modem flash from this?
Uploading... give me a moment
APK3 (from 6.0.1. No 7.0 CP/BL available yet for the W8 variant, but no problem with the 6.0.1 ones)
Bootloader https://drive.google.com/open?id=0B7NTwhbole31b0xHMjNOZFJ2MVU
Modem https://drive.google.com/open?id=0B7NTwhbole31MTFBNEh5Zi1LNzg
Thank you very much for the quick reply and for the uploaded files as well!
May I ask what you did to get those files (trying to learn all this stuff as I find the world of a rooted phone an awesome one but there is much to learn!) ?

I extracted the BL/modem from the full Generic APK3 firmware I found here a few weeks ago. I wanted the latest available modem/BL for my W8 S7 edge too, but I didn't want to subscribe to SamMobile just for that. I suggest you to keep that link, it has many up-to-date files and firmwares available for our S7 edge variant.
Having them separately is more convenient than having to download the full firmware (2GB+) though but well...

OTA android 7 update for g935fd not working

Hey guys,
The OTA update for android 7 has come up in my s7 edge duos. I have tried downloading it twice........it gets to 100% and says there an error and that it's the wrong version.
Not sure what to do.........any ideas
Download and flash the rom through odin.
Did you ever flash a different rom? Which brand is respectively CSC has your phone?
Never flashed another rom........bought the phone off amazon.com............it's zn international version, but looks like the supplier got them from UAE.

the supplier may have gotten from UAE but the csc may not be from there.
you can try downloading the Rom from samfirmware and flashing that way.
Thanx for the reply guys, how can I find out the CSC on the phone? Also if I flash with odin, Will that erase all the data on the phone? And will it trip the knox?
Why is it that the update doesn't work? How come the software on my phone doesn't match the update it's downloading? Is it something the supplier/seller has done to the phone? Like modify the software?
Thanx guys
Install Phone INFO ★Samsung★ and you get all necessary information.
If you flash with Odin Know won't be triggered. You can keep your data with the three following requirements:
- The firmware you flash must have the CSC included you use at the moment.
- You need to use HOME_CSC file instead of CSC file.
- You may not tick re-partition.
Keep in mind to only flash firmwares designed for the Exynos variant.
Sellers on Amazon sometimes get phones from a different market and flash then a firmware fitting your market. This is rather a replacement than a modification (since the whole system is still official) and Knox is not triggered. However, one effect is that OTA may not work or gives "phantom" update notices. There's no restriction aside of that and you can just use Odin to remain updated.
You can post screens from all pages of the app I mentioned and we can see what's going on.
Hey Andiling, really appreciate your help pal. Here are some pictures you requested. Thank you

[F8331] Change stock firmware for a better LTE signal

Hi everybody,
I'm new here, I have bought my first sony (used) but I notice that the LTE signal is so poor specially indoor. The seller hasn't saw me that the firmware is an UK fw also I live in italy, infact, after a little research, I noticed that there is a carrier's app called EE and the fw version installed is of EE carrier's. The phone is sim unlock. There isn't root and I haven't unlook the bootloader.
My questions are:
- Can I change the stock uk firmware putting in an Italian stock firmware?
- Can I change it without root and without unlook the bootloader?
- How?
- Is there a guide that I can follow?
- Can I change the CSC for preserve the ota upgrade? How? I'd like to change fw preserving OTA update.
I don't wanna unlock the bootloader and root the phone cause I don't want lose the DRM licenses (widevine specially). I'm not interested to rooting or make any modding.
I'd like to put a stock room without bloat apps and with a strong lte signal.
Here the Info about the phone:

I think it should be possible to just Flash another Regions Firmware via Androxydes Flashtool.
No need for unlock as long as u have any offical fw (XperiFirm comes with Flashtool and downloads offical files)
But I may be wrong tho, this just came to my mind in the first moment

Thanks you LoaderFabi for the suggest, so I will waiting for a confirmation about that.
Meanwhile can y tell me a link to a guide and download the tool?
Anyway, thanks again ?
You can flash any region's firmware without unlocking the bootloader. You need Xperifirm to download the firmware, and Flashtool to flash it.

Ok, and about the OTA's update? Will it be automatically? Or do I have something about? And how?
Can you link me a guide to flash the fw and, eventually, to do something about OTA's update?
Thanks

Since it's an official firmware, you always get updates OTA (i think XZ will no longer get updates but no need to worry). I didn't see any guide to flash, i'll probably today write a guide to flash firmwares.

SamFirm does not load any info for an ATT S8+ / Does not show "USA" Region option. What do I do?

I hate ATT. I hope their stupid company dies soon.
Anyway, I'm trying to flash my ATT S8+ that is running Android 7.0 with Android Pie. I first attempted to use Frija and it said that the ATT "CSC code not supported". I then tried SamFirm and when I input the phone model SM-G955U, it doesn't show the "United States" Region option.
Ideally, I would like to flash my phone with an unbranded Android Pie. What do I do?
UPDATE: I am able to find many different firmware files on SamFrew. However, I still need to know if I can flash an unbranded XAA file from there?
Will it work? And do I need a modded version of Odin to flash? I came across some guy's youtube tutorial that says only to use a modded Odin to flash unbranded firmware on an ATT Samsung phone, but unfortunately his video is from three years ago and so I'm not sure if the modded Odin he's linked to will be compatible and be able to flash the much recent released firmware updates.
UPDATE: Issue resolved. I went ahead and flashed it and it worked.
