I believe since you're flashing official firmware, it won't be tripped. I bought an S6 from Germany and flashed with 3 UK firmware and can confirm my KNOX counter hasn't tripped.

I've skimmed through the tutorial video and it doesn't seem to have tripped Knox.
I'm looking to switch my s6 from TEL (Telstra AU) to XSA (Open AU).
Has anyone else tried to do this?
Cheers

will this work with an att s6

I just did it with the Optus S6. Worked perfectly.

Can't find firmware for US
I'm on a T-Mobile Galaxy S6 right now. I want to follow your tutorial, even if I am in the US should I use the UK firmware model you used in the video? Is there a special international unlocked firmware for the US version (like there is one for Spain, for UK, etc).
Also, if the UK model will work on my T-Mobile phone in the US, will I suffer battery hits because the phone will be looking for UK bands or will it recognize that I'm in the US and will only look for the US bands? Thanks!!

It would look for bands based on the SIM I believe, but whether you can flash another region ROM is questionable. I thought there was something to prevent that, but I'm new to Samsung. I'm also curious if this will work. If it does, I'll just purchase an AT&T version as opposed to an unlocked one and then use this process.

Well the BTU model has always meant internationally unlocked in terms of Samsung devices, so hopefully this will work. I'm trying to flash it on my T-Mobile device and then rooting it. Does anybody have any idea how to change the model number of the phone to BTU as well so I can get OTA updates?

@madscientistdam
Looks like there is another BTU build added to the sammobile site wonder if anyone will receive a ota?
http://www.sammobile.com/firmwares/database/SM-G920F/BTU/

Received an ota this morning guys, and it was the new build I posted above this post.

Just did this to my Vodafone AU S6 and it worked a treat. Also got an OTA update after a couple of reboots. Knox is still intact. Should work for other Aussie telco phones. Fixed my random freeze's and reboots that where happening flat out at one stage.
*Update- still getting random lockups, even after setting up as a new phone (using no backup). Flash went fine though...

Question. Would this be good for an Ireland Three carrier S6?
Cheers!

Debrand an American S6 Edge (Verizon) for use in Germany
Hi!
You write in your video tutorial that you don’t suggest it for American smartphones. I have a Samsung Galaxy S6 Edge from America (Verizon branded, firmware: G925VVRU4BOG9) and want to use it in Germany. So far, I have some annoying limitations (I can’t send text messages and I can’t roam). Do you – or anyone else reading this – have a hint or even a little tutorial for me? I’m so annoyed as neither Samsung nor Verizon or my German SIM card provider FONIC offers me support. The phone was a present from an American friend. So I’m not the original customer. I guess that’s one reason they don’t help. Whatever: I’ll appreciate your help! Thanks…

And a hard brick is exactly what I don’t want to risk…

this I assume only works on the International 920F version of these phone, you can flash most any region on these (hence international is your first clue), this does not however work on the (American Carrier) branded phones like Sprint, ATT, Verizon, US Cellular ect ect , these are I am told firmware specific, I tried flashing T-Mobile firmware on a sprint phone and brick city, I mean even sprint could not get it back up flashing sprint firmware with their jig... so beware. U.S. Based Carriers got you under their thumb.

What happens if I flashed another country firmware??

Suppose in the case I bricked my phone and I don't know the baseband version of it. Now what is the option to recover? Flash stock firmware via Odin but don't know the baseband??? What will happens if I flash another country stock firmware?? Will the phone hard brick?? Or it will work fine?? Thank you
The worst case is that your sim card will not work with that software. This is only if your phone is carrier locked.
If it is unlocked, or neverlocked as others put it, then you can flash any firmware you like, as long as it is for your respective phone model.

You should flash Nepal firmware then. It would give you better (more match) CSC code. The CSC (Consumer Software Customization) code contains the info about software packages specific to a particular region, carrier branding and also APN (Access Point Name) settings for data connection.
In my case, my S4 i9500 was made in Vietnam and when I received it, it had a Thailand firmware on it. It is a network unlocked phone. I live in USA. The first lollipop firmware came out was for Russia. So I flahsed the Russian firmware. My CSC showed that it is a russian phone. I used that phone on AT&T network that available in USA, China and Korea, and I had no problem.
Nothing will happen.
@sway8966
Are you really to suggest him to flash Nepali firmware on UK phone? I'll unlock it (the carrier-lock) first and then flash other countries' firmware if need.

Sorry to bump this up but im having problems with my s6 edge (Maybe because of this).
I recently acquired a phone from a relative from UK. The OS is android 7.0 and the carrier is three.co.uk (H3G), we have reset the phone to its factory settings and accidentally didnt noticed that it do auto update on the OS, then this bootloops starts to occur.
The phone isnt network-locked because the phone can receive signals, messages and phone calls on local sim.
Now upon browsing around SamMobile, There is an available Firmware for this mobile and even the firmware which is available to Philippines but only ver. 6.0.1
Is this possible to use the PH one or still i go to UK(h3g)?
help please
once i take the firmware from other countries and then i install to my phone,
does my phone will going to operate that firmware even if it come from another country
because i tried to find firmware according to my respective country unfortunately i missed it.
so please i need your assistance ..please

Understanding flashing

Hi guys,
Just bought a galaxy s5 from my uncle who worked in Canada, the phone was locked to Telus Canada I unlocked it through unlockBase which was superfast and easy.. I have now really started using this phone and have now realised that the date format is different to what I usually use, I have done some research and found that an update stopped the ability to change it to prevent blackmarket sales or whatever.. I was thinking can I just flash a uk rom on the phone or not? But will it relock the phone? Also will rooting the phone enable me to change it? Although I don't wanna root because my online banking app won't work or WhatsApp?
Thanks in advance guys

This is definitely one of the strangest reasons for rooting...
But since it's a Telus phone its definitely a G900W8. You can cross flash all and only G900w8 firmwares so i.e. you can flash Rogers on bell, wind on telus, sasktel on koodo, etc

Thanks for the reply, yes rooting was the last option as some apps won't work.. so if i was to flash it i would only be able to use telus firmware which is US could I flash a UK firmware on it? And if I was to flash it would it still stay unlocked or will it need reunlocking?
EDIT: done some more research.. will changing the csc code on my phone to one of a uk firmware, then installing a uk firmware work?

Nope because anything outside of Canada uses a completely different phone model and flashing between different models will likely lead to a bricked phone (phone is damaged unrecoverable)

Buying a carrier-branded S8 from another European country

Hello all,
So I'm tempted to buy a Tim-branded S8 on Amazon.it because it's crazy cheap currently. I'm not in Italy but from what I've gathered online (and confirmed by a review on the product's page on Amazon), branding in Italy doesn't mean sim-locking so it should be usable with my local carrier. I'm in Europe anyway.
The only major difference with an unlocked phone (since it doesn't seem to have any hardware trace of the carrier) will be the software : potential TIM-related bloatware, delays for updates, etc.
My question would be : could it be possible to flash an official "clean" image, without affecting the phone and its warranty ? If so, which reference should I use ?
Thank you very much !
Yes, was going to ask if it was also sim locked.?
What county are you in and what sim do you use?
Out the box, if sim unlocked, it will work anyway.
Unless you want any advanced features.
Fw wise it's not a problem. I went the other way though, flashing EE ( UK) firmware into an unbranded unlocked BTU version to get VoLTE to work. It caused no issues.
Belgium but I guess European models pretty much have all bands available across Europe...
Thanks for the feedback !
I have the tim s8 here in the UK, flashed the h3g firmware and have WiFi calling and volte functioning without issue.

hi
Im also interested in buying a tim branded phone (https://www.amazon.it/gp/product/B071RSVYSH/ref=ox_sc_act_title_1?smid=A11IL2PNWYJU7H&psc=1) and was hoping if someone who has one could answer me couple of questions.
1) Does the phone have universal warranty? I mean if something was wrong with it and it needed any repair, could I just take it to a local Samsung store?
2) The model number on amazon site is G950, is that different from G950F? i couldn't find any reliable info on this..
Thanks in advance!
If the phone is designed for the European market then warranty applies regardless where you are (within Europe).
All European models are F-models.
You can flash an unbranded ROM through Odin to get rid of any branding which does not trigger Knox.

Samsung Pay Australia

Hello fellow S8 users,
I've recently purchased a Samsung S8 SM-G950FD from eBay as I wanted the Dual SIM capability. Version image attached, I'm not entirely sure where it's from.
Unfortunately the Samsung Pay version on the phone is in Chinese as are the promotion, images attached.
Can someone tell me if it's possible to get the Australian version on Samsung Pay on this phone?
Can I just update the ROM to an Australian version? If so, would I end up losing the Dual SIM capability?
Any help on this would be much appreciated.
Thank you.
Any suggestions?

Your Australia cards should work as Australia already have support for Samsung Pay. I have setup few of my Indian cards with Australian version phone. I guess you need to bear with the Chinese though. Updating XSA room will definitely disable the Dual sim option and I am not sure 950FD support 950F.

Yeh the Samsung Pay Application doesn't like my American Express Card....
It states that Amex is not supported in my country, but in fact it's working on my Samsung S6, and my Gear 3.
So you think changing the firmware to AU I would lose the Dual SIM capabilities?
It might just be easier to try and get the Samsung Pay and Samsung Pay Framework from AU ROM and extract it to mine maybe?
If it's anything like the S7, you should be fine putting the Australian firmware on it. I got an S7 edge from the UAE and had to flash German firmware and the T-Mobile CSC to it for spay to finally work. It'll be trail and error, but the multi sim function never went away for me.
Since almost all the international S8/S8+s are on the multi CSC ROM, all you need to do is reset your phone (preferably from the recovery menu) and put in the Oz SIM and reboot. All the regional features are activated, and you get Oz SPAY.
Using that method, I am currently using the India SPAY on an Afghanistan S8+ (Dual sim) and Taiwanese S8 and both work with all cards.

I've actually tried to restore to factory setting 6+ times with an assortment of sim cards from Vodafone, Optus, Telstra, Macquarie (Telstra variant), samsung pay keeps loading up as Taiwanese version (Chinese)...
I've recently asked a friend to extract his Samsung Pay & Framework.apk, it still loads Taiwan Samsung pay.
I think it's region locked?
I'm going to try and restore to XSA Firmware, apparently this worked for the S7 guys, whilst retaining Dual Sim functions.

Did you try to factory reset from recovery? Vol up + Bixby + power, wait for few seconds it goes into recovery. Put the regional SIM in, then reboot. It will reboot twice and activate SIM specific features (prominently tells you that it's doing so).
Also please post a screenshot of the Settings->Software information screen (Service provide SW ver. is 2nd last row) both before and after you complete the process.
Someone recommended me this solution after I had a similar problem with my UAE S8 and flashing other country firmware no longer works without supporting SIM card. Download Samsung Pay version 2.7.03 and try that.

Means that it doesn't matter which firmware you flash if you don't have the country's sim card because s8 will default back to factory CSC. Only way to change CSC without root is to flash with the supporting sim card installed.

Has anyone here got the Australian Samsung Pay app onto the Taiwanese dual-sim model? I purchased an S8+ at $799 (compared to the RRP of $1349) but I don't want to factory reset if I don't have to.
Anyone got spay working? Pkease share what firmware version are you using.

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.
