Installing different firmware version on Galaxy S7 Edge

I currently own an Australian Optus carrier variant of Galaxy S7 Edge (OPS) and want to install an Australian unlocked variant of Galaxy S7 Edge (XSA) since unlocked variant has recieved 2 updates since its launch but carrier variant has received none..
1. So my question is will this trip my KNOX Warranty and will it disable my Samsung Pay app use?
2. Also, if I install another country's Galaxy S7 Edge firmware that has the same model number, will this trip my KNOX Warranty and disable Samsung Pay Use?
3. Which country (code) receives the fastest new updates for the device SM-G935F?
4. Lastly, can I install a Galaxy S7 Edge firmware with a different model number? I want to try South Korean variant firmware..

You can flash any official Samsung firmware, and it won't trip Knox.
Someone else asked this earlier today: http://forum.xda-developers.com/s7-edge/help/to-flash-generic-australian-rom-to-t3364559
Also, Samsung Pay isn't in Australia yet, and won't be for some time.
The Aussie carrier devices should get the latest update soon hopefully.

Thank you for your reply. Just one more question! I heard that if a phone is rooted, Samsung Pay app is not usable on that device afterwards so will it be the same for installing the other firmware? I know that Samsung Pay is not yet available in Australia but I would like to use it when it's launched.

Correct. Samsung Pay won't work on a rooted device.
Also, if you root, you will trip Knox. You can't use Samsung Pay on a Knox tripped device.
Even if you go back and flash stock firmware, this will not reverse Knox. This is permanent.
But if you just flash Samsung unbranded firmware over your Optus firmware, this is ok. Samsung Pay will still work.

Just to clear up something else, does your handset need to be unlocked before you can flash another official samsung firmware?

Samsung Galaxy A5 SM-A520F/DS questions

HI i just bought galaxy a5 2017 duos model.
I expected it to have samsungpay, but it is not preinstalled and i can't seem to download it.
it has nfc chip so i am guessing it should support it.
perhaps it's because of the firmware's country stetting.
I found out that it has pakistan firmware installed.
does anyone have a5 2017 dual sim verion which has samsung pay enabled?
if so, would i be able to get samsung pay to work by flashing different country's firmware?
i checked smamobile and there was austrlaian version firmware available, which is perfect as i am in australia and bought the phone form grey import supplier.
does anyone know it is safe to flash SM-A520F firmware onto A520F ds version? i couldnt find ds spesific firmware on sammobile.
Thank you in advance

Hi neighbours, Indonesian here.
I'm using A5 2017 DS version as well and no Samsung pay installed also.
I guess it's only installed based on region which have Samsung pay services running on those selected country

Yeah it works fine flashing the Australian rom. I'm with Telstra so went with that one and Samsung pay is enabled. You also get VoLTE with Telstra.
My phone had the UAE firmware on it originally. Dual SIM function is still there too, not that I use that though.

INS ROM for SM-G935F?

Does the Indian version of the ROM for International S7 Edge exists? I can't seem to find it anywhere. Read a post that said I can use a INS rom for SM-G935FD. Is it risk free? No bricking and stuff? Does that mean I can use a second Sim Card if I flash a G935FD ROM? I am currently on XSA (Australian) Firmware because of Whitepages and Samsung Pay. Is it worth flashing? Plan to return to USA after a month and wanted to know a better alternative to the XSA firmware that works well with USA carriers.

How to make Samsung Pay work on Galaxy S8 purchased from UAE and living in India

Hi Guys,
I am planning to buy a Galaxy S8 from Dubai and I live in India.
I have a few concerns,
One being the samsung pay and volte not working on india networks, although I read this can be managed by flashing an Indian Firmware and changing CSC or something of that sort.
I don't know the technical aspect of it at all so if someone could please guide and explain me.
Also I wanted to know the risks associated with it and also would it void my UAE warranty?
Also which model am I supposed to buy?
The G950F or the G950FD?
If someone could please walk me through the entire process.
It is cheaper by 300$ if I buy it from UAE than India so is it worth doing so?

I've a Galaxy S8 G950FD imported from UAE. Samsung Pay and 4G/LTE work fine here in India. Also, changing CSC is easy and it probably won't void your UAE warranty. To change to INS CSC, you just need to do *#272#IMEI# and then select INS CSC. If this doesn't work directly, then flash any INS firmware for G950FD using Odin and then do the *#272#IMEI# to change CSC.

How to flash the Indian firmware? Is it safe to do so I'm scared of bricking my phone.
Could you please share the method which you used and was successful for you?

Hey there,
I have SM-G950U (which is for US market) and now I'm living in Europe, can I reinstall firmware to one from my current region even if it is for SM-G950F model?
SM-G950U ---> SM-G950F
Thanks.

I don't think it will work, flashing a European firmware has boot loader included, European boot loader not compatible with US model

lol we can't flash exynos rom to Qualcomm

Yeah... I thought so. I'm asking cuz apparently I cannot obtain and use LTE+ in Europe even though it has the same frequencies. Now it says LTE which is around 11 mbps...

You might be able to flash only the CSC as they dont contain system binaries just config files but I have no idea if it will work or now so be prepared to restore from soft brick id you try

I have a G950F.
Does anybody know if I can just flash the CSC from the G950U (ATT) firmware to my G950F International phone?
I know you can't flash the full firmware as the G950F has the Exynos processor and the G950U is made for the Snapdragon.
But is it safe to just flash the CSC file only as I want to fully use Samsung Pay, wifi calling, VoLTE, etc?
I'm using the Australia firmware (XSA) for my G950F.
