This tutorial will help uk samsung galaxy s6 owners to debrand the S6 if locked to a network it will also get rid of all the network carrier bloatware and the good thing about this it will then allow you to get OTA Updates Quicker because u wont need to wait for your carrier to test the firmare before rolling it out Enjoy https://www.youtube.com/watch?v=-ey2Qn_n0t4
Wouldn't this trip the flash counter which would also mean losing your 2 year warranty?

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.

I currently own the Galaxy S7 edge UK (unlocked) unbranded handset, however my network is with Three. Supposedly you need to have bought the handset from them to have 4G Super-Voice (VoLTE/HD-Voice) enabled, so I'm wondering if anyone can help me source the firmware. I'm sure this will be useful to anyone else on the Three network with an unbranded handset.

Do you know what csc code they use?
Might it be this one?
Please note that this is just pure guessing. But it was the only one I could find that had anything to do with "three"

I'm trying to do the same thing. Have you managed to get it workking. I found the following three firmware: H3G-G925FXXU3QOLD-20160111115713.zip
Latest BTU firmware has it as default (3 sim on unbranded S7 Edge).
Use the Samfirm tool (http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647).
1. Set "Model" as SM-G935F and "Region" as BTU.
2. Check "decrypt automatically".
3. Extract the decrypted file with WinRar or similar, then use odin to flash.

No need to lock will stay default unless it auto changes by itself but for me its okay and 4G voice works fine as default like on all devices
There is no need to flash H3G firmware any more. I have returned back to stock unbranded volTE works.
Just use smartswitch to revert back to stock firmware!
Sorry for the bump but does anyone know what settings were changed on the S7 root directory to allow unbranded devices to connect? I looking at modifying the files myself for the 6P as Three don't seem to be taking the rollout seriously for unbranded devices - so far the only thing I've found that relates to H3G is the mcfg_sw.mbn that states "No VoLTE" within, though the Swedish H3G configuration allows VoLTE, so I'm going to try modifying that unless anyone around has any ideas?
I've got a three s7edge couldn't get volte to work ended up flashing btu firmware and there is it listed in Network and it's working when there is no coverage as I get a volte displayed along with the empty signal bars

My stock firmware on a UK model has VoLTE enabled for Three UK. It's just not prioritised and only kicks in when low 3G signal.
As far as I understand it it will only work when u have no or very little signal
It's worked for me a few times such as deep inside a building

I want to know whether 935w8 supports VOLTE service or not? And if it does supports, then ehat is the procedure to so.
Please help me out guys. I want volte on my device.
VoLTE will work only if jio networks provides configurations for W8 variants. Better go to Jio office and put on a request. They can only solve your problem.

The G935W8 probably does support VoLTE in Canada, but it won't in other countries due to the lack of an Indian CSC for the W8 variant.

It'd be impossible to get one, because Samsung would never allow it.
You could try exchanging your phone for a G935F/FD and flash the Indian firmware on that to get VoLTE.
Although you'd lose some money, you'd get VoLTE and the ability to get Indian software updates.

Are there any custom ROMs (and CSC files) that allow the S8 to successfully have WiFi Calling and VoLTE on the AT&T network??
I am running RENOVATE ICE 3.0 but you need the Notorious Kernel 1.9 for Volte to work on T. Some kernels do not support Volte, but Notorious does. You also need to flash ATT from the Flashable CSC Selection V1.0.0, and create/edit the /efs/imei/mps_code.dat and put ATT in there. You can also delete the /system/omc/ATT/res directory to get rid of the annoying T jingle and boot screen. You then need to call ATT and ask the friendly customer service person to update your IMEI. But when you give them your current IMEI, they will not be able to find it since it is not a ATT phone. So they will use the IMEI of a similar phone. That will get Volte to work. But WiFi will not as I think the IMEI must match exactly in their system for WiFi to work.
Hello. I'm also trying to figure out the same. How can I unlock the G955U? is that even possible?
Ideally I'd like to get the CSC Patch installed so I can get WiFi Calling on ATT, as I do not have any reception in my area. Any Help here would be appreciated.
Can anyone help here? Thanks.

You can flash csc seletcion after the rom.
That package contains the csc of att and the US generic. That generic is the one that I use and it works volte, wifi calling in tmobile ...
Hi Eddie, would you happen to know how to Root the G955U? its the Unlocked version of the phone. I've followed every step for CF-Auto-Root through Odin, but it fails every time. It seems like the Bootloader is locked? Any help would be appreciated here.

If you mean network unlock, then follow the ToS on AT&T mobile and eventually you will be allowed to unlock your phone. And for you to switch from the firmware of SM-G955U to SM-G955U1, you gotta go to this forum: https://forum.xda-developers.com/galaxy-s8/how-to/rd-carrier-switch-root-snapdragon-t3597473

Well i don't know from experience with at&t firmware but at&t should have wifi calling by default. If not and if wifi calling is an important feature towards you, then the last resort answer you have is to flash unlock firmware onto your device since that's the firmware everyone can use while it supports wifi calling and VoLTE (Voice Over LTE)

Once again, per other threads and myself, simply flashing the att firmware will only give you VOLte. You can toggle the wifi calling but it will say your account doesn't have this feature after about 5 seconds. If u call them and give them an imei number that is to a device that is an att device with the feature it will work. This is different then tmobile which will allow u both without doing anything except flashing their firmware.

Hello all ..... ( and @Tkkg1994 )
I'm still trying to get a definitive answer --- Has anyone personally been able to get an unbranded S8 or S8+ to activate WiFi Calling on the AT&T network (not TMo or others) ??
I'm trying to facilitate an issue with using S8 Ports on my unbranded S7 Edge where we can get VoLTE to work nicely but WiFi Calling will not activate (on the S8 port based ROMs).
I am aware (and have been for quite a while) that you must have an AT&T branded IMEI to get this to work on AT&T. I am also aware that this step is not needed on TMobile or really any other network.
I have tried the branded S7 IMEI that works great on my S7 to activate WiFi Calling while using many (most) S7 based ROMs. I have even tried branded IMEI's from ATT branded S8's and S8+'s .... but I can't get WiFi calling to activate while on any of the S8 port based ROMS (I get VoLTE nicely with many ROMS esp the latest BatMan S8 port ROM)
So to troubleshoot I am trying to confirm that even with the S8 or S8+ that WIFi Calling is or is not a possibilty ??
Thanks

I am no developer, but I believe there are two possible causes in the case of T WiFi failure on Exynos:
Perhaps T requires the IMEI to exactly match as a security measure, and since they cannot use an International model IMEI it will never work.
Or there is something specifically compiled for the Snapdragon process and so when it is extract it will not run on the Exynos.
Either way, it won't work. I posted a LOGCAT when enabling it failed, but it is beyond my capability to debug and no one seemed to be able to figure it out.
Hey guys! I brought my unlocked T-Mobile USA S7 Edge to Germany and it works fine with either Vodafone or Telekom, but no Wi-Fi Calling works. They suggested me to get one of their phones but since I had to fully pay for this device to get it unlocked I don't want to throw 800 bucks away like that.
Is there a way to get this to work? Is it possible to flash a different CP / Modem / Radio / Firmware that could potentially get this working? I know the bootloader is locked but I'm not sure if there are any workarounds as I've seen people successfully getting G935U firmware to work on their unlocked T Mobile S7E.
Any advice? Thanks in advance!
Anyone? ?
You can easily flash "T" model with "U" firmware - been there, works well.
What do you mean by wifi calling? Ggl duo/hangouts, whatsapp, all that kind of apps work fine on whichever firmware.
PS. Flashing T/U versions works even if your bootloader is locked (mine is).
Hey!
Thank you for your reply. I managed to Flash the U Firmware but WiFi Calling or VOLTE still won't work. I can over whatsapp and it's cool I guess but would be good especially when calling some people overseas who don't UE whatsapp as wifi calling means no international roaming charges.
That or also the ability to just flash about any custom Roms would be cool too.
