T867U - Any way to flash T865 or T860 Firmware? - Samsung Galaxy Tab S6 Questions & Answers

Good evening everyone!
I have a Tab S6, SM-T867U, the T-Mobile LTE variant. Unfortunately, as with all carriers, T-Mobile is terrible at releasing updates. I was wondering, does anyone know if there is any firmware that I can flash to get it up to Android 12?
To be honest, I don't even care about cellular on it because I can pair it to my S21 and get 5G data speeds instead of LTE, so if there was a possibility of flashing the T860, I'd be open to that.
Just looking for guidance.
TIA!

[Q] If I have a GSM device that supports either T-Mobile or AT&T can I....?

So, I have an NVIDIA Shield, and am very interested in the LTE version of the upcoming NVIDIA Shield Tablet, but I need to know something. I intend on buying the LTE variant for data. I have no reason to have voice, but I want to use data. I am under the impression it is a GSM device, and is for T-Mobile or AT&T, I want to use my Verizon LTE data. The question breaks down to whether I can pop my Verizon SIM in and use it on the LTE-only bands? I know the Nexus 7 had a LTE radio, but I am under the impression it was somewhat carrier specific. Anyways, if somebody has the answer, that'd be great.
Thanks in advance.

SM-G925F on T-Mobile performance?

Just really want that Emerald Green color and don't mind the extra cost. Anyone have a SM-G925F that they use on T-Mobile and can describe their experience, and if LTE is working properly? Thank you.
shouldn't be a problem. seems all he bands line up so it would work with lte and everything. just not wifi calling... unless you flash a tmobile based custom rom
Hey @kaydash did you end up getting the g925f? how's the internet speed with T-mobile? I'm considering getting the same but I read that it wasn't compatible with the AT&T LTE frequency bands so I was wondering whether there would be a problem with T-mobile too...thanks in advance!

Verizon - SMG925VZWE - Is it possible to use the GSM radio?

Greetings XDA S6 Edge!
I am the happy owner of a used VZ branded, S6 Edge. Can anyone comment on the possibility of enabling the GSM radio in this device? I'm a Tracfone user but it would be lovely if there was a way to test out MVNO providers that are not using CDMA.
I tried to search the forum but couldn't find an answer to this specific question.
Thank you very must for any replies!
I haven't tried it but, you may be able to flash the CP file from a newer build of a US Unbranded S6 Edge.
The VZW S7 Edge [G935V] accepted the G935U firmware as long as you were flashing a newer build than what was currently installed.
And the G935U radio firmware actually supports all bands in the US, GSM & CDMA.
I would play around with it. If you get it to flash and boot up, worst case scenario for your phone service would prolly be that you would only get Voice or Data service. Not both.
But you never know. If you can get it to flash, there IS potential there.

Can I use any ROMs with the SM-T827?

I purchased a Tab S3 thinking it would be a WiFi model. Turns out it is a SM-T827 (US Cellular) version. I never plan on using a mobile plan with it. Are there any problems if I use ROMs for the 820 or 825 models?
It will not work, they use different roms as they have different internals and also has an imei being a celluar version.
That is too bad. I hate Samsung's UI and slow version of Android.
This isn't an answer to your question, but...
I'm curious how much bloatware they put on the US Cellular variant. I've seen where people flash Verizon firmware successfully onto the US Cellular version, but haven't discussed doing that in the other direction and am tempted to try it.
The Verizon version of Pie has a ton of junk on it.
Thanks

T865 on T-Mobile

I was wondering if anybody is using the international T865 on T-Mobile, and if so, how is the LTE signal? I know this model doesn't have all of the T-Mobile LTE bands, but I believe it has a couple of the important ones? I ran an international Tab S2 on T-Mobile, and it worked pretty much just fine in Los Angeles. I was kind of curious how this might work now, if the network has changed since then or whatnot, and then how the merger with Sprint might affect it in the near future. Any info is appreciated!

I attempted to flash the international T865 on my unlocked T-Mobile S6 LTE with Odin and a Patched Odin but in each case it failed.

Yeah I don't think that works. Have you tried putting a smartphone sim in your T-Mobile S6? I'm sure the system will recognize it as a tablet and not a phone. That's why I want to order an 865 international model. But then again I guess I might look into how much it costs just to add some tablet data to my plan.

I have a smartphone sim (no difference than an normal sim) and get mobile data which allows me to use the phone when WiFi is not available (I don't want to use my phone as a hotspot). The T-Mobile LTE tablet cannot make phone calls or text but can use the text and call on other devices option on Samsung phones which allows you to use the Tablet using your phone number.
On other samsung devices the US models use the Snapdragon chip while the international model uses the exynos chip which can easily unlock the bootloader and root the phone or tablet. I understand that the S6 LTE tablet is using only the Snapdragon chip worldwide so rooting may be much more difficult. However the international version should have the OEM unlock available so the bootloader can be unlocked. Normally I only get the international versions and root, but if is getting more difficult each year to root the Samsung devices. I bought a used S6 LTE and am happy with my tablet.

So you have a smartphone sim in your T-Mobile Tab S6 LTE, and can get unlimited data? Is it a T-Mobile SIM or another carrier? I tried that some years ago with a different tablet and it didn't work because the system recognized it as a tablet and not a smartphone. That would be cool if it works though, I don't care that much about calling and texting, but unlimited data would be cool.
I like the international models too because they can be used like huge phones lol, but they don't have all of the T-Mobile LTE bands, but I think they have enough that it works okay.
