I'm in the UK and I've acquired three brand new sealed S7's - SM-G930A - which I would like to sell, but they appear to have an AT&T/Sprint specific version of Android - I've booted one and it keeps trying to install DirectTV and other US-centric apps.
Is there a way to put these on a UK or EU ROM that doesn't have all this unnecessary bloat, so that they can be used outside the US WITHOUT breaking KNOX (which would mean I am unlikely to sell them at all?)
Thanks!
The AT&T variant of the S7 is built upon a Snapdragon CPU. All of the European variants are built upon a Exynos CPU. Breaking Knox isn't your biggest issue; you can't install a European version of an S7 ROM at all.
Additionally snapdragons have a locked bootloader, so you can't use a custom ROM as work around either.
Your best bet would be flashing the G930U firmware, it's the unlocked firmware for Snapdragon that has no carrier specific bloat. It can be flashed via Odin without affecting Knox, but you may need the patched Odin for it to not give mismatch errors. https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572

I'm looking at upgrading from my Moto E4 and settled on the Galaxy S7 over the Pixel due to the MicroSD slot. I now have questions as to which version to get.
I understand that it's relatively simple to flash the unlocked firmware on any of the devices. Could I just simply find the cheapest, good shaped S7 and flash the unlocked firmware and be satisfied?
I'm currently on Sprint's 1-year free service promotion until September 2018. So Sprint compatibility is needed for a while. After that, I want the freedom to be able to hop back to AT&T or Verizon (or one of their MVNOs).
Should I just buy a Sprint S7 now, then when my service is up, flash the new firmware then? Or should I buy a T-Mobile version and flash the 930U firmware right away? The universal unlocked model is significantly more expensive, so I just want to make sure I'm covering all my bases.
Depends on your goals. Flashing via Odin is quite simple and easy for the S7, but the US models all have a locked bootloader. That means you can only flash stock firmware files, and nothing custom. No ROM's and no TWRP.
If you're happy with than then you're set, if not you'll need the international Exynos model, as it can be unlocked and flash custom.

no ROMs is OK with me. the exynos version won't work on my current provider, so can't go that direction anyway.
Hello everyone, I have a Samsung Galaxy S7 (G930F - Exynos - International).
I've rooted the phone, but fully unroot it back with a stock rom. So, knox has been tripped because of it. I don't really care about root anymore.
I was wondering if it's possible to flash a g930u firmware on it and be able to use Samsung Pay afterward.
G930U firmware is for the snapdragon US models, you'll brick your phone trying to put it on the G930F exynos. Totally different SoC.
What's your goal exactly? If it's better US carrier support you can try flashing the CSC utility but it needs TWRP https://forum.xda-developers.com/galaxy-s7/development/utility-flashable-csc-selection-30-t3392949

so i can use samsung pay.
currently, samsung pay will not work on S7 international or exynos model.
So according to this https://forum.xda-developers.com/s7-edge/how-to/samsung-pay-knox-warranty-void-t3549449
CSC has to match your country, so you're likely going to need to flash that CSC utility to a US carrier. Since the G930F is the international version there's no stock US firmware for it, so custom zips are likely your only option.

You definitely should NOT try flashing a U firmware, because lots of things will go very badly. It's not even made for the same SoC as the F (international) version.
Tripping Knox has blown an e-fuse on your motherboard, so unless you replace it there is no way to restore it to 0x0.
And as for using Samsung Pay, that is not possible, because of Knox being tripped. Currently there isn't a workaround for that and so using Samsung Pay is not possible.
Hello everyone. I have had a problem quite some time now. I was attempting to root my Galaxy S7 from United Wireless (which is a regional provider) and I ran into an issue in which a firmware file I was attempting to flash over (with Odin) apparently was incomplete or Corrupted. Now I have rooted nearly every device I've ever owned (omitting the Note 8 I currently use for fear of ruining this one too). I have never however run into a problem with incorrect firmware or incomplete firmware. So I went to go look for the stock firmware for the device, and to my dismay, I find that United Wireless uses a firmware that is either; custom to them, difficult to find, or is not a firmware created by Samsung themselves. To this day, about 1 year after bricking, I have yet to find a way to get the S7 working again. Does anyone know of a universal Firmware or something that can be flashed to get it working again? Maybe even enough to get a custom rom on it??
- Thanks in advance,
Evanzire
Assuming you're in the US, you can flash the SM-G930U firmware, as it's the unbranded firmware for US devices and should flash on any US model S7.
If you boot into download mode (Home + Power + Vol Down) what model does your device show as?
US model S7's use snapdragon SoC's with a locked bootloader, so the only working root method is to use an unstable leaked engineering bootloader that allows (some) boot modifications. Custom ROM's are impossible, and root uses non-standard methods.
Hi Everyone,
I bought Samsung Galaxy S7 Duos from Dubai.
The phone becomes so annoying as it has some kind of Adware built-in, which always opens different kinds of websites, pop-up ads and PlayStore links (after every few minutes).
I tried every possible way to get rid of it but nothing useful, even the factory reset or hard rest doesn't work. Because the OS it self is buggy.
According to its Settings, the phone has Model No. SM-G930FD, and Android 7.0
Now I want to install the fresh and updated firmware, so I can free my self from this Adware and can enjoy Android 8.0
I have downloaded Android 8.0 firmware for SM-G930FD
I tried Odin to install this new firmware but encountered a new issue:
According to Phone's Download Mode, the phone model is SM-G930S instead of SM-G930FD
This means someone installed the local ROM on the Korean Phone. (am I right?)
Now when I'm trying to install Android 8.0 firmware for SM-G930FD (of any other region) it shows the error:
"Secure Check Fail: (PIT)"
I am out of ideas on what to try next
Whatever it says in download mode is what the phone actually is, everything else has been faked.
It's a common scam to use modified firmware to make a phone appear to be a different model, as some models sells for more than others.
This is likely what has happened to you, and also the cause of the apparent adware.
Stock G930F or FD firmware will bootloop a G930S, which is probably why Odin is refusing. You would either need to flash stock G930S firmware, or use a custom ROM compatible with G930S

Thank you for the clarification
Now when I'm sure that my phone has G930S model, the option of stock ROM is only one: Android 8.0, Korea (SK Telecom)
1. By Googling a lot about this scam I'm afraid that changing the ROM may covert the phone into Single SIM version!
2. And if I install Korea (SK Telecom) ROM, will it lock the phone to Korean network only?
3. Do you think that "Korea (SK Telecom) ROM" will change everything into Korean?
Can you please clear my doubts
I don't know enough about the Korean stock ROM to answer those unfortunately.
But I do know many custom ROM's are compatible with G930F/FD and S, so I would assume allow dual SIM.
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
