Flashing other variants?

Hey guys, I recently broke my s7e and got a check from Samsung to replace it. I'm looking for try cheapest way to do it and saw a deal on slickdeals with a comment that said:
The Sprint galaxy S7 edge can be flashed to be the 935U version, not sure about the non edge version. All S7 and S7e sold in the US have the same hardware though, so the Sprint version does already have the hardware for the 4x4 MIMO, flashing it to the U version if possible should be enough to put it on parity with the T-Mobile version on most things software wise (including Wi-fi calling I believe) and 100% on par hardware wise.
Yes just root, install custom recovery, download a tmobile rom that has built in aroma installer and you then own a unofficial ALL bands and services for tmobile s7
Is this at all true?

Well you could probably ODIN to different firmwares, but we have a locked bootloader and therefor no custom recovery. Could also try different ROMs on the exynos versions of the phone. But since they're different hardware versions I doubt you would get 100% functional software like wifi calling and VoLTE.

I thought that was the case. It was just really cheap and would be a great way to get another one if all I had to do was Odin the tmo firmware.

Yeah that would be a great idea. I know the phones are identical hardware wise. If I were you I'd do some more research to see if you could flash the sprint phone to tmobile through odin. I think it SHOULD work but having never tried I can't confirm.

I just flashed my Verizon 7 edge to the t mobile firmware and was able to use band 12, WiFi Calling and carrier aggregation. Should be the same for sprint.
Only thing I was told in the Verizon thread was that the firmware for t mobile is baseband 3 and the U firmware is baseband 2 so there is no going back until Verizon or U firmware is undated to baseband 3

Someone told me that Verizon was now in v3 with the latest update, is that not actually the case?

Not sure honestly.

I believe you mean the bootloader v2/v3... not baseband. Baseband is referring to modem.

7.0 for AT&T?

It's been awhile since I have owned a Samsung and I'm about to get a Note 4 so I was wondering what Android 7.0 Roms are out that will work with the AT&T Snapdragon model. I see Roms for all the international models and even the T-Mobile variants but I don't see anything for the AT&T variant. I will have to brush up on my flashing and Rom'ing skills as it's been too long since I have done it but I am familiar with doing all this. Thanks guys.

There is no custom ROMs for at&t model to be honest. At&t lock there devices down completely so at present there is no root, no twrp and no ROMs. Dont think there ever will be

callumbr1 , yeah, I have been doing allot of research and it's very disappointing. But there is always getting a t mobile device unlocked and still being able to enjoy some Nougat love.....

Moving a G930T to Verizon?

Hey! I have an unlocked S7 from T-Mobile. What all would I need to do to get it working with Verizon? Would Flashing Verizon firmware onto it (I actually already did this once for the Nougat Beta) make the CDMA radios work?

Yes you can flash the Verizon firmware or the 930u firmware and it will work on Verizon. There is no 930u Nougat firmware yet though.

International Firmware

Before I start, this is the first android phone I've ever owned so the question may or may not be stupid.
So I live in India and I saw the trade-in deal for the S8. I was in need of an upgrade (iPhone 6) so I went for it as I was heading to the U.S soon. I heard that the international version gets updates sooner than the unlocked U.S version. Can I just change my firmware to international, get earlier updates with no drawback? If yes then why have I not seen a lot on this?

Pretty sure the firmware is locked to the device unless you root. I had an unlocked international S6(920?F) . It updated a lot earlier than the W released in Canada.

If the device you get is G950F (international) then updates will come sooner. If you get any other version they are for specific regions, so if you get G950U (US unlocked) you can't flash international firmware to it. Can only flash firmware for the model you get.

Then what are the benefits of people switching carriers for example? There seem to be a bunch of threads giving a tutorial on how to change firmware to different carries e.g. From a T Mobile to Unlocked.

For stuff like WiFi calling, voLTE, removal of bloat some csc tweaks

Guess that's unfortunate.

Curious about the released firmwares.

I have a note 9 and it appears the firmware are universal. I have flashed ATT, Tmobile, Verizon, Unlocked firmwares on my note 9 with no issues. Is this going to be the same going forward?
My question: Is the galaxy s10, s10e, s10+, s10 5g going to have universal firmwares we can flash from all carriers?

Those are all US carriers, so they are all on the same chipset. So it makes sense that their would be no issues with flashing firmware from different carriers. This is because the carriers generally do not get to modify the hardware, just the software.
The firmware issues are more when you get into the non-US versions. So the non-US SD chipset phones might have minor differences, making their firmware iffy, and the variants using the Exynos chipset will definitely have different firmware which just flashing could cause problems.
