SM-T837T Tab S4 firmware Switch

Hi Folks
I have the T837T from T-Mobile. My Question is if it is possible to flash a firmware from the T835?
Also it has a Simlock, anyone knows where to unlock the device?
regards

This will sound stupid but do yourself a favor and sell it on ebay while used ones are still fetching good money and then buy an international korean model, no sim lock plus 6gb ram. I almost bought the tmobile one til i found out about the korean version.

Firmware Verizon VZW to unlocked version XAA ?

Hello,
I just bought the note 10+ N750U from verizon under the firmware N975USQU1ASH4 (VZW)
I do not have a Verizon Sim card but Orange (French operator), so I would like to put the phone with an unlock version (XAA?)
Is it possible ?
Or a more suitable firmware for France (even if the processor is an exynos in France and here a snapdragon)
How to do it please?
thank you very much in advance

If you just bought it. You may be in a difficult situation. Verizon does a sim card lock for 60 days. You have to use it under Verizon's network for the 1st 60 days.

No, I haven't received it yet but it's a second-hand model that has more than 60 days so a priori no problem there

It's possible ?

If your phone is already Carrier/Verizon Unlocked, then you can Flash the Unlocked Firmware.
Read about it in this discussion thread:

SM-G9880 Flashing Question

I recently just bought a S20 Ultra that has a unlockable bootloader. A little while back, I had a Galaxy S9 that I could completely convert the entire device to U1. Is that even possible with this device ? To fully convert the CSC and bootloader ect, to a US model ?

That was then. Each model is specific to a region and can not be flash with software from another region. I.E you cannot flash G9880 with firmware from G988U or G988U1 or the other way around.

What exactly changed from the S9 to the S20 that made that impossible ?

Any luck? I just got one in Canada and it only has 3g ad 4g so I was hoping I could flash a csc file.

So I attempted to edit the band config using QPST and QXDM, but I'm very unfamiliar with both programs and how to actually read and write information to the modem using those programs. Definitely not for the average user. Back in the days when devices had ESN numbers, I used to flash software using QPST and QXDM but there is a lot that has changed with those programs, and I wouldn't even know how to do that stuff today. If anyone has any knowledge about those two programs that can help me unlock all the US 5G bands for AT&T and Verizon that would extremely helpful.

Buying N975U (US Cellular) and using in the UK

Hello, I want to get the snapdragon Note 10+, so a friend can get me the US Cellular N975U but I will be using it in the UK. So, if anyone can help to answer my doubts:
1) How do I check if the device is region locked?
2) Will I be able to receive the SW updates with my UK sim here? or am I going to be restricted to flash manually via odin etc?
Thanks in advance

Give this a look & then contact US Cellular with the device IMEI, they'll likely need it to check for unlock status.

As for getting updates with a non-US Cellular SIM Card, I'd definitely ask about that as well.
Hopefully, someone here @ XDA will chime-in with their experience.
