I have a SM-G9300, which is a Chinese dual SIM model of S7, with a Snapdragon chipset. It's in excellent condition, with the box and charger, so I'm selling it.
I'm just wondering if there's stock firmware for it that will make it more sellable in the UK, that doesn't have a bunch of bundled apps intended for the Chinese market on it.
Is it the same board that's in American or other English speaking Snapdragon models?
If so, will both SIM slots still be recognised if I were to flash American firmware?
Or is there a dual SIM, Snapdragon S7 that was made for an English speaking market, that I could use the firmware from?

Back in 2017, a guy posted asking about the same, he found multiple answers that I find helpful.

Check his post.

Since there's an official TWRP available for Snapdragon devices, I believe there's hope for you, even though not a lot of custom ROMs exist for your variant.

There are ideas you could try, present in the post, but don't forget the warning of flashing other model's firmware, and what could happen to your phone.

Thanks. I hadn't even noticed this thing didn't have the play store on it! The thing is, it does have google play services and google play services updater on it? is that normal?

No, and yes.

Chinese variants don't implement Google Services, just like the modern Huawei devices wasn't allowed to.

Maybe someone tried to install the Google Services packages, similar to what is done on modern Huawei phones, I can't tell you further.

But there's an Oreo Galaxy S9 ROM available for your device, of which will make your device look like an international S7.

Thanks. The firmware that's on it is 100% official, downloaded via frija and flashed with odin. I had a look at the changelog for the official firmware, and it actually does mention that some new Google features had been added to it.
So there's Google services, Google Play Services updater, and a Google section in the settings menu, but no Play store and no Google apps in any of the menus. Google drive PDF viewer does show up in the list of installed apps in the settings menu though. Makes me wonder that there might actually be a way to install the Play Store without custom recovery, that maybe wasn't possible on previous versions of the official firmware.
For now, I have unlocked the bootloader and installed TWRP. I was hoping not have to root it, but it still wouldn't boot after flashing the DM-verity package, so I flashed Magisk and it booted.
I will check out the Oreo ROM for it, thanks. Do you have a link?

I just found out that all I needed to do to get the Google Play store on it was to install the APK file!
As of more recent firmware updates, Samsung have been releasing the firmware for Chinese models with all the underlying Google Services architecture in there already, just without the Play store. Literally just needs the Play store APK.
Been messing around all day trying to flash the Hong Kong CSC file on this thing, cos I really wanted it unrooted for selling it. Stumbled across the Google installer for Chinese smartphones. Tried that, and it was failing on installing Serviced Framework. Turned out that it was failing because a more up to date version of Services Framework was already installed, and all I needed was the Play Store APK from APKmirror.
