Can I use any ROMs with the SM-T827? - Samsung Galaxy Tab S3 Questions & Answers

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

Hardware Variations

Alright, I've been reading like mad here. I'm getting basically two sets of stories to the same question.
Q: Is there ANY hardware difference in the US/CAN models?
I'm aware of the INT Version, and the KOR version. But, for CAN/US despite different modem software. I assume the hardware is in fact identical? I know for example that my t-999v has the same FCC number as the us TMO version. If this is in fact the case then any s3 should work on any US or Canadian Carrier with some sort of modem hack?
I'd love to get your takes on this guys. Thanks again.
Canadian version is same as ATT version. Sprint and other CDMA carriers have different radios.

Galaxy SII on small US Carrier (Carolina West)

Hey guys,
I'm most likely switching over to a small regional carrier, Carolina West sometime this week. They offer the SII and I can't find much specifically about their version of the SII. I definitely want to install a custom rom on the phone. What should I look out for to make sure it's compatible with the ROMS on this site. I believe they piggy back on Verizon so the phone may be the same as Verizons.
Thanks!
Check out the bands used. If it uses the 1700 band, you will need to make sure that the custom rom supports this.
Every GSII variant has its own forum. You dont have to worry about not finding rooting instructions and custom roms.

[Q] Help: i717 LTE Universal (without any AT&T App)

Hi All. Just got my hands on AT&T Galaxy Note LTE i717. So far, its Unlocked and rooted through Odin. Going to to CWM 10 soon. Projecting a ParanoidKANGdroid 2.3.3 rom too (or any other rom).
But my main concern would be, with my locality in mind (i'm in singapore):
1) Would I be able to clear all AT&T apps? Meaning is it a must for me to have at&t apps inside to keep the phone working?
2) Would the phone work in singapore after flashing? Currently, it is working fine unflashed and in AT&T stock.
3) would my LTE function work? (It does not have a mini sim card slot but a normal slot)
I've searched through but I might have missed some useful links. Apologies if I do. Do guide me to the right path if possible.
Thank you.
If you're going to CM, why are you even asking about AT&T apps?
As for working in Singapore, you'll have to compare frequencies between your carrier and AT&T's. And the i717 doesn't have a microsim.
You should be fine!
If you install a custom rom it won't have at&t bloat, or apps. You can download them if needed.
Take notice of what modem you're on now. It's in settings - about phone - baseband version. If it's working fine make a note of it. Installing custom roms shouldn't change your modem. I'd find a downloadable zip of it for peace of mind. Updating thru kies can change the modem. So if something goes wrong you can revert back to stock and still have the modem you desire.
Thanks lots guys! appreciate much!

There's a galaxy note released for the Singapore market. It's called the n7005.
Novena is a Rom based on that firmware btw...and since its Singapore Rom, no AT&T apps.
As far as running an aosp Rom, no AT&T apps are needed, and as long as you copy down your apn data before flashing just to be safe, there's no reason you shouldn't get lte,
Singapore uses the same lte bands that American carriers use.

I don't mean to contradict you sir, but are you sure about the LTE? according to this list of LTE networks AT&T uses 4 and 17 and Singapore uses 3 and 7.
http://en.wikipedia.org/wiki/List_of_LTE_networks
Those numbers are bands and frequencies just for the LTE network but the frequencies are the same 900 and 1900 mhz for the 4G network. So, like a lot of at&t users, 4G is the more common network in Singapore.
Gotcha, the post said lte so I figured that's what we were focusing on, not 4g.my bad!

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.

Changing firmware

I currently have a unlocked T-mobile S21 that I am using on a Verizon based MVNO. Is there or would there be any benefits to switching the firmware over to Verizon instead of using T-mobile that's on the phone?

I'd suggest switching to one of the 'open' versions, that has a multi csc capability and should thus have all the necessary ability to use the mvno you prefer. The t-mo rom may work, but it almost certainly won't have the full capabilities, such as all bands used, possibly volte working, vowifi, and there may be other things also.
Thank you. You make a valid point about going to a unlocked version.
I tried to flash the Verizon firmware along with the user_data files with no success.
I still get all of the T-mobile splash screens and all of the their bloatware. The service provider software version still states TMB/XAA,TMB/TMB but my baseband and build number are Verizons. Maybe I am not knowledgeable to this extend.
All I would like to do is get rid of T-mobile and make it a Verizon phone.
