I have just got a pre-owned Tab S2 T817W which is a Canadian version from Bell Canada.
It has been unlocked and I can put in another carrier's SIM card and use it.
However, it is in stock 5.1.1 stock ROM and I want to upgrade to the latest Marshmallow.
My questions are:
1) If I flash the latest ROM from Bell for this T817W, will the ROM lock it back to Bell only?
2) Can I flash other carrier's ROM, eg T817A (for ATT) T817V (for Verizon) etc?
3) Do I need to root it before upgrading if i want to have root in Marshmallow?
(EDITed: I found the answers to the questions myself. I was able to download a Marshmallow firmware for Canada instead for Carrier specific from Sammobile. Everything works as I have wished for, it is still unlocked, fingerprint detection works better and the tab even runs faster.)

I've just purchased a new S6 with the same model number as the T-Mobile version but it's unlocked and unbranded. Does anyone else have this phone and when do you think it may get marshmallow?

You will get the update anyday now. It would be awsome if you could get a system dump for that firmware youre running. we could reallydo some development witg that and be able to get marshmallow along with you.
I have the same phone, also purchased unlocked though Best Buy. Will we be getting a separate software update from T-Mobile? Once released, how can I get that system dump? I can see how it would be usefull for development. Haven't rooted because I don't want to trip knox and loose warranty. Impatiently waiting on the update. Didn't know if I had to wait for the T-Mobile update to roll out first.
To my knowledge our phone is just a different CSC under the G920T variant... For G920F, which is the international version, mostly European, different CSCs mean different regions and/or carriers. Likewise, for G920T, there are two CSCs: TMO (which is T-Mobile) and XAR (which is our bloatware-free version). That said, if the TMO firmware comes out first, we'll be able to flash it manually with Odin but we'll not receive OTA. The downside is that we'll have to bear with the bloatware until we flash back to the XAR Marshmallow after it's released. As for Knox, as long as we're flashing official stock firmwares from Samsung Knox won't be tripped.
Hi all,
I bought the Galaxy S6 from AT&T when it came out, but switched over to T-Mobile from AT&T last year. Because of this, I have been unable to get any updates and have been stuck on Android 6.0 when the current release is android 7.0, so I've been thinking of flashing my phone. I was curious as to whether I'm able to flash my G920A with Tmobile's G920T rom? Would it work? And if so, after I flash it, would I be able to receive updates normally from T-mobile's servers, as I'm currently using a T-mobile sim, or would I have to flash every subsequent update?
Thanks
Doubtful, since AT&T has a locked bootloader. If the bootloader was unlocked you might be able to try.

You cannot flash a G920T firmware on a G920A. First off, Odin won't let you because the G920T firmware is only signed to be flashed on the G920T.
And even if you somehow rooted and used FlashFire to force the firmware onto your device, the firmware would brick the device, and without a USB jig or SD card port, the brick would be permanent.

I too am seeking answers on this as I have an SM-920A I brought over to t-mobile. Unlocked the phone, installed the t-mobile SIM and the phone works fine, except, it still has all the old ATT apps I no longer need or desire to be there AND without the T-Mobile apps installed, I cannot use their LTE Signal Booster. Is there any way I can install these t-mobile apps that would have come with the SM-920T load?

Just do this and remove the AT&T apps you don't want completely.

So, what can be done -- if anything--to solve this issue?

Hello,
I have some noob questions to ask before trying this out on my G920T (Baseband version: G920TUVS6FRC1 - which is running Android 7.0). Here's a little bit of background about my situation, I was with Tmobile Prepaid up until the end of December 2019. I ended up getting my phone unlocked by Tmobile and transferred my number to an AT&T Prepaid account.
I was looking to try and get HD Voice/wifi calling working on my unlocked G920T. My question is, when flashing different carrier firmwares, does it matter what the storage capacity of the phone is? Would I be able to flash G920A firmware (no matter if it came from a 32GB Samsung S6, or 128GB (not sure if AT&T ever had a 128GB version of this phone)?
Also I read that it is better to use the princecomsy (my apologies if I messed up on the name) version of Odin rather than the non-cracked versions. Is that correct?
Would I be able to flash different carrier firmwares regardless if my bootloader is locked?
Thank you to anyone that can help.
I'm currently living in Japan, but will be moving back to the US in a couple months, so I recently bought a refurbished Galaxy S20 FE 5g that claimed to be unlocked from the US and had it shipped to Japan.
It works fine with my Japanese sim, but came with AT&T bloatware installed and the model number is still SM-G781U. To my understanding, an unlocked phone should have a '1' after this, signifying that it's unlocked. Because of this, I don't get OTA updated and am still stick on Android 10 and One UI 2.5. So I figured I'd learn how to flash it and do that. It says the CSC is G781UOYN1ATIG, but then when I go to Service Provider it says ATT/ATT/ATT.
Could I just flash the firmware for the SM-G781U1, CSC: XAA onto it and be able to have a fully unlocked and updated phone? Sorry I'm a bit new to this and don't want to brick my phone. Thanks!
I did the opposite (from SM-G781U1 to SM-G781U) and worked with no problems. I needed ATT Wi-Fi calling that worked only with the ATT firmware when I was on Android 10. I suggest to do a factory reset when switching between branded and unbranded but (in theory) you should keep your phone data if you flash the HOME_CSC file.
Hi all, I just got a SM-G973U1 (unlocked snapdragon) to replace my old S7 international version that doesn't have working VoLTE. AT&T is shutting down 3G in February, so I need to set up this new phone so that it works in LTE only mode.
I'd like to use TWRP recovery and Magisk root, but I doubt any ported ROMs will work because of Samsung's proprietary drivers for VoLTE/HD voice. What's the best stock-based ROM available for this device? Alternatively, where can I find detailed instructions for installing these items myself and removing Knox and other safeguards from the existing stock firmware (possibly using adb shell)?
If necessary, I'm willing to use the ATT CSC code on this phone. This is not the current CSC on this device.
I'm returning the phone because I haven't found a way to unlock the bootloader.
