As the title states, is it possible to flash another version of velvet firmware onto the T-Mobile variant? I see the guide in unlocking boot loader and rooting. Just trying to see if we can get some other things unlocked that are on other variants like face unlock and screen recorder (with media sounds, all the screen recorders I’ve downloaded can’t seem to record the internal audio of the phone)
I'm afraid not. All other variants of the Velvet in the states are running Snapdragon processors, while the T-Mobile variant uses a MediaTek Demensity processor.

My Uncle got me a verizon galaxy s7 from USA and now I am trying to run a 4G sim in it but it isn't working as VoLTE is not activating ( something called Advanced HD Calling) as verizon wants verification for it and as the device is here we can't do that
I was thinking of flashing an Indian Firmware on it
Will that help me ??
Or is there anything else I can do.
Please Help.
update 1 : I managed to unlock the bootloader
If it's a Verizon S7 it'll be a G930V which uses Snapdragon, you can't flash Indian firmware on it because India uses the G930F model which has Exynos SoC.
Also despite the bootloader unlock option being available and toggleable in developer options, it doesn't actually do anything on USA models. Don't attempt to flash custom recovery, it'll brick.
Your best bet would be to flash the unbranded USA firmware (G930U) which should rid the phone of Verizon, however it's unlikely that'd let you use local carrier VoLTE.
I can run an Indian Sim in this device its just that the Volte doesn't work
I can still make it work with an app from the provider
should i just make do with the app or try the unbranded firmware?
also the other s7 my uncle sent me has FRP locked and the seller can't obviously give me his gmail to unlock it.
Is there anything I can do to bypass it or do I have to send it back to USA? also i have no clue if it has OEM unlocking enabled
I have a T-Mobile OP7 pro that I've had unlocked from the network, and I've been running the international version of OOS for some time. This week I tried changing to Havoc OS (because I've used it on previous phones), and now I'm stuck in a bootloop. I don't even get to the ROM's boot screen. I know I can put factory software back on there, but I'm not ready to give up unless someone here knows whether it's impossible to run AOSP ROMs on a T-Mobile OP7 pro.
You're better off converting the phone into the international variant using the MSM tool. I have a converted unit, and all ROMs work properly after conversion.
Hi all
I am looking to flash a non us variant stock rom with hopes of unlock oem option to show up because appearntly in north american versions it's missing in developer options permanently. I was able to flash another region once via odin,the origin rom was A515W (canadian variant) to A515U1 but could make the jump to A515F after it. I'm wondering it could be due to reason that the second time bootloader version wasn't higher like the first time (or it could be that A515F only works on dual sims ?)
My end goal is to instal custom roms so if there is a shortcut to without going through these hoops I would appreciate it.

Have you found any solution? I am opposite. I have a US variant wanting to unlock oem bootloader option on my us variant A51 but it is not available after setting up developer settings?? Please share any ideas
The US variants have locked bootloaders for a few years now. You can't unlock even by flashing firmware from other countries. The only way is a paid service. You can find it here: https://forum.xda-developers.com/t/...unlock-for-samsung-us-canada-devices.4215101/ or here: https://forum.xda-developers.com/t/sampwnd-usa-model-bl-unlock-info-u-u1-w.4201689/
My Moto Z2F has gone insane & I need to replace it. My boss has an S10e that's google locked, ATT but can go to Android12. It's 2 years newer than my Z2F which is stuck at Android8. Good idea? I'm on T-Mobile, but my understanding is that except for firmware, the hardware is identical. Can/should I try to burn T-Mo firmware? What would I gain/lose? If I should do it, how? I've never messed with any phone's firmware before, other than accepting OTA's.

No, you can't use the moto firmware on the Samsung device. Android firmware is built specifically for the model number that it is installed on. You could flash S10e AT&T firmware on a T-Mobile S10e and vice versa but not a firnware from a completely different device manufacturer, regardless of how similar the hardware is. There are very rare occassions where firmware is interchangeable between to completely different manufacturers but 99% of the time, this leads to a bricked device. Samsung devices can only flash Samsung firmware for the specific model number of the device or from another Samsung device with the exact same hardware, such as AT&T S10e to T-mobile S10e. Samsung uses Snapdragon and Exynos CPUs, an S10e with snapdragon can flash a firmware from another S10e that has snapdragon CPU but not a firmware from a S10e that has Exynos CPU and vice versa.
If you want to use the S10e, you need to bypass the FRP lock(Google lock) then flash the most up to date firmware available for that specific model number of S10e for your specifc region/carrier.

Thanks. I didn't intend to try to use Moto firmware, I meant Samsung TMo firmware on ATT Samsung. But I'm not clear about limitations of ATT firmware with TMo carrier. Will that be a problem? And I don't know which CPU. I've been able to obtain a little info from the S10e via USB, but I don't think I should list it in the open here. Can I PM it to you for info about my exact hardware? And as I said, I'm totally new at trying to flash it. Is this something that can/should be done via a local TMo store? I've been a PC tech for 30+ years, but messing with cell phones is new to me.

AT&T and T-Mobile are interchangeable, you can flash both ways. But, you should be able to flash AT&T firmware and then use a T.-Mobile SIM to use it on T-Mobile network.
Flashing the firmware is fairly simple.
Do a Google search for:
"Return to stock (your model number)"
That should find the tools and instructions.
Thank you. I've seen something about perhaps not being able to use wifi calling on TMo with ATT firmware because ATT left it out. I've seen other stuff that says it works. Somebody else said that TMo's Visual Voicemail won't work without the TMo firmware. Do you know anything about that? I've seen quite a bit of contradictory information & don't know what to believe. It already has ATT firmware, so if I don't NEED to flash TMo to enable those, I may leave well-enough alone. How do I determine which CPU I have? The info I got via USB doesn't tell me.
Hello, I would like to preface this by saying that I don't actually live in the US. I got this used unlocked AT&T Galaxy S21+ a few months back and an issue I noticed after using it for a while was the fact I was not receiving any OTA updates due to the fact I was not using an AT&T SIM card.
Now I want to switch AT&T to carrier-free firmware where I will be able to get regular OTA updates automatically
My current specs:
Model: SM-G996U
chip: Snapdragon 888
Baseband version : G996USQU1ATLF
CSC : G996UOYN1ATLF
AP/CP : G996USQU1ATLF
Is it suitable for installation?
https://www.sammobile.com/samsung/g.../SM-G996U/USC/download/G996USQU5CVDB/1640229/
N.B/: May doing this flash will brick or damage my phone?
On SamMobile, underneath my device model, there list of several firmware labeled with different US carriers. As long as the firmware I flash is under the model number I have (SM-G996U), nothing should break, right?
Please suggest me firmware. I want to get rid of carrier barrier and want to get regular updates automatically safely.
Did you try the rom? I have the same problem
OTA is CSC based. You'd have to use Samkey to unlock the CSC to a unlocked US one.
Flash the u1 xaa firmware. Works on my phone in canada
I have a similar issue!
So I received a refurbished S21+, it is unlocked and all but it has AT&T bloatware and I can't update to oneui 5.0... I live in italy but this phone comes from Germany and apparently has a US AT&T firmware (SM-G996U-OYN-ATT). I was following a tutorial with odin to flash to SM-G996B with ITV, which is the italian version with android 12 and oneui 4.1.1 is it safe to do so and then get the android 13 update the standard way? Could I straight up get android 13 and oneui 5 flashing the most recent rom or is it even worse?
The other solution I thought about is that I could just get the U1 XAA, but i have U for now and I don't quite understand if it's completely risk free or not.

I'm having the same issue with my Samsung S20 Ultra 5G SM-G988U i bought the device yesterday and it accept my local Sim here but the issue is that there is limited features, for example I can't turn On/off my mobile data on and I can't change network mode like selecting from 4G to 5G
