Flash SM-G920F (DBT) with the latest BTU firmware - possible?

Hi,
I am getting somewhat unhappy with the lack of official updates for my unlocked SM-G920F (DBT) S6, which I bought from Amazon Germany. Looks like the UK variants have a much more recent BTU firmware dated January 2016, while mine is stuck with October 2015 update.
PhoneInfo shows the following:
Product code: SM-G920FZKADBT
Original CSC: DBT
Firmware's CSC: DBT
Active CSC: DBT
Bootloader: G920FXXU3COI9
PDA: G920FXXU3COI9
CSC: G920FDBT3COI6
Baseband: G920FXXU3COI9
Would it be possible for me to flash the latest official BTU firmware without tripping Knox?
Many thanks for your comments!

Yes.

Many thanks for your response! This is a good news
Do I need to change CSC somehow, or would it be sufficient to just flash the latest BTU firmware with Odin?

Switching is not going to help you as the BTU version is just as old as the DBT version. COI9 is the latest release for both countries.
You will have no benefit by switching to BTU.
It seems that since October, Samsung has only updated the carrier versions of their builds and not the Open/carrier independent versions.
There is one notable exception, which is the NEE version for Denmark/Sweden. This at least has the security updates dated Dec. 1 and is, aside from Marshmallow, the best you can do for the SM-G920F.
What I did was just flash NEE on top of the existing firmware (in my case BTU). That provides a mixed CSC version for the time being but can be healed by flashing BTU again, when Samsung finally comes out with a new firmware.
What I would recommend for you to do is to complain with Samsung. I have emailed them and made it clear that they promised monthly security updates in August 2015. Their promise is what prompted me to purchase the Samsung S6 in September. After the purchase, they delivered exactly one monthly update for it, then 4 months of delivering nothing.
They have not kept their promise and I suggest you (and everyone else who is upset by this) let them know. In my case I have also asked them for a return of the phone.
This is also something I will now attempt to initiate through my dealer.

You are right, the latest BTU is the same G920FXXU3COI9 :|
I already complained to Samsung twice, the last time was yesterday, but they were not forthcoming. I also bought the device hoping for the monthly updates, but didn't get any since October 2015.

And it's only going to get worst for updates as they be very few & far between for the S6 this year once the S7 is launched.

Yeah, this is kinda sad.

Quite honestly the S6 is the best phone I've ever used and I would love to keep it. But the update policy, especially considering the promise Samsung made, is not acceptable. I'll keep you updated on my attempts at returning it.

Thanks! I thought about returning mine, but won't even try: it's easily one of the best phones for the money, the only alternative for me would be an iPhone 6/6s, and I'm not prepared to go that route

hey, of course you can flash btu firmware on german handset. that's what i always do after buying samsung's phone. it's the cleanest one with no bloat.

I just received a response from Samsung basically telling me to f*ck off and contact a local repair shop. Sent them the following:
Hi,
Many thanks for your response! Unfortunately, my location (Cyprus) is not on the list. Moreover, I own a factory unlocked and carrier-independent EU version sourced from Germany (DBT), which does not depend on the local carriers.
As far as I can see, the latest update for Galaxy S6 (DBT), as well as for the UK unlocked and unbranded version of Galaxy S6 (BTU), is G920FXXU3COI9, dated October and September 2015 respectively - I checked Sammobile, XDA forums and other Internet resources to verify this. My understanding is that no further updates have been released to the aforementioned unlocked and unbranded EU versions, either DBT or BTU, thus my question is: where are the November 2015, December 2015 and January 2016 security updates promised by Samsung and "released" on paper?
I bought the device based on the promise that it would get frequent security updates, only to face another letdown by Samsung. I would appreciate an explanation and an estimate of when the above updates will become available to my device.
Thanks!

Im on PB6 too. Samsung should release the next update with april security patch within the next few weeks

Does the location and language settings used for initial setup has anything to do with the delay of the updates? Just curious to know, where do guys get the International version in USA?

global version (930F) is available at swappa dot com, Best Buy, and B&H Photo/Video

Been on APB6 too on my G930F for a while. It's an international version I got from eBay, using it on prepaid. Initial language setup was set as united kingdom but I changed it to united States. I'm a bit jealous hearing other European origin variants got updates

G930FD here. Duos version. Didn't expect the updates to be so quick. Already on April patch. While my Duos G4 isn't getting quick updates as promised by LG. LG only gives priority in updates only for the International(Single SIM) version. But Sammy's case is quite unexpected.

Ditto here, but still on PB4 / Feb patch. (G930F)
I've only had it a few days, but this is the only reason I got this one over the carrier variant. Meanwhile T-Mobile and Verizon have already released updates with the April patch.
Lovely! ....

Have NOT got the June update yet? HELP!

I flashed an unbranded UK April S7 firmware from http://www.sammobile.com/firmwares/, and since haven't received the june update that released about a month ago, any help?
Also is it normal to have apps like samsung pay in the uk firmware?

Have you installed also the csc file? I had that problem of not receiving OTA and it was because i did not put the four files in ODIN.
ps: i used the CSC and not the home_csc version
ps 2: I flashed the Australian version

Change CSC - Korean Note 20 Ultra

Hello,
I just bought a Note 20 Ultra Korean variant with Snapdragon processor.. I am using the phone in India.. it seems to have some KT carrier branded firmware in it.. it also has some carrier specific settings in the menu.. I understood that the CSC of my device is KTC and Korean unbranded model has KOO CSC.. is there a way I can change the CSC to KOO and install stock Samsung firmware on this device? I have no idea how to change the CSC.. tried*#272*IMEI# and it doesnt work.
I am on September security patch.
Please help me.

No one? Someone please help? :-/

I can't find July software for Korean Note 20 Ultra anywhere. I am currently on September patch. Need to downgrade to July patch to use Mysterious-Dev CSC changer app.

Still listing July firmware. https://www.sammobile.com/samsung/g...e/SM-N986N/KTC/download/N986NKSU1ATH1/357960/

AFAIK, the Korean(SM-N986N) model was released with August security patch right out of the box, i.e. there was no firmware build for consumers with July security patch for this model. So searching for a July-patched build might not help.

That's with August security patch, having July-end build.

I own this model and live in South Korea. The firmware came out in July upon launch with August security patch. There has been one security patch update released since then (September 4). So, maybe the OP is SOL about downgrading unless the original firmware will still work for changing CSC. I don't know, as I've stopped messing with that stuff years ago now.

I think my phone came with July security patch.

The only reference I can find to ATGI firmware is testing from Samsung back in July and the pic was in Korean. I pre-ordered mine and it came with ATH1 firmware out of the box in August. You're not going to find that firmware anywhere easily. I can't even get a hit on a Korean search engine. Good luck.

Why don't you flash KOO firmware with sep security and check? You got nothing to loose

Without changing the CSC first and then flashing, it will have no changes whatsoever. I tried. ?
