Hello everyone,
My impatient boyfriend wants to flash his New Zealand carrier branded S7 to the british BTU Oreo update.
It has been a long time since i've done any flashing work with odin and i've all but forgotten the method and what is involved besides downloading the btu update from sammobile.
So if someone can give me a Quick refresher, and if this is even doable without tripping knox/breaking secure folder - it would be Greatly appreciated!
Thanks! :good:
Instructions are literally all over the forum if you open a few threads
And amusingly underneath the download on sammobiles site too lol, although you need to add all 4 parts, not just AP

Flashing stock does not trip KNOX, only flashing custom

Hello everyone
I was wondering if it's normal not to get ota updates after flashing other region firmware. I got a Galazy S7 and it came with Spanish ROM - I flashed the Italian one and now to do updates I need to use Odin all the times.
I did not flash any other files other than AP. Should I have replaced the CSC as well? Any other benefit?
Using Odin doesn't bother me, but it would be easier if the phone could do everything itself.
PS: I am actually thinking of flashing the UK version of Android N! Is it good?
Thanks foir your patience
Andrea
you should use all the files ap cp csc bl
Since there is no official Nougat release in the USA yet, I was planning on installing the "BTU" Nougat official firmware intended for the UK. Do I need to do anything with changing the CSC to use in the USA, or just flash everything as-is in the firmware download? I don't understand if the CSC change is REQUIRED to match the country you are using the phone in, or just recommended. The current Marshmallow build is showing a CSC of OJV (middle east)
What are you USA folks out there doing? I am on Straight Talk (AT&T sim).
My current phone is giving me a lot of problems, and I'd really appreciate a response as I need to get switched over to this S7 ASAP. I realize I can just use Marshmallow but am really hoping to get to Nougat so I don't have to reflash and potentially lose data down the road.
Thank you!
If the CSC you want to change to is not included in the CSC already on your phone, you'll need to use CSC of the new ROM (Not HOME_CSC) along with the other 3 sections, and check the "Repartition" option in PIT settings of ODIN
This will wipe your phone back to factory settings
Are you rooted?

He doesn't need to check repartition. Despite the fact that it is designed for downgrading and unbricking (exclusively, in most cases ), it is not required to do that if only CSC change is needed. Only thing he need to do is using CSC section of the ROM (not Home_CSC because it is preserving old settings in the phone, message to The Founder of the topic ).
Generally, when I was switching to BTU I flashed Firmware with CSC different that BTU (for example Sweden rom) and then flashed BTU sofware. CSC has changed flawlessly
And when you have rooted phone, you can change CSC manually. That extremely ease you effort.
i would just flash the firmware and the csc that comes with it because then you will get updates in the future. if the csc doesn't match the firmware you wont ever get updates so just do a samsung cloud backup and flash the nougat But its weird that someone in the usa doesn'ty have nougat because i thought usa was 1 of the first with nougat.
RiTCHiE007 is right. If you want to receive OTA updates, CSC must match with the type of firmware it comes from. That is why you need to change CSC from US to BTU. Here is a thread that will help you out providing explanation of the topic.
Anyone who owns G930F and didn't have VoLTE or WiFi calling enabled on Nougat firmware BUT managed to get it working afterdoing "x" please share how to do it.
I'm tired of waiting for my Network to release the firmware...
Step by step guide would be welcome
My service provider supports both techs.

Of course they do! :good:
Basically just want to know what would happen if I flashed carrier branded csc only with Odin.
E.g. would my phone refuse to boot, would my phone be carrier branded if it succesfully boots, trip Knox, etc...
Any info welcome - tired of googling the answers or searching XDA forum for answers.

Might have some carrier preinstalled crap but it won't trip KNOX nor prevent the phone from booting

That answered some of my questions, thanks.
Please see screenshot for my mutiCSC firmware. I am running Android 7 but haven't changed CSC since I got the phone in December 2016. I got it with Marshmallow on it. Everytime I upgrade firmware with Odin I select Home CSC so my CSC never changes.
Since the solution is in the CSC (afaik), which CSC do you recommend I flash with Odin? I understand how to flash with Odin if CSC not in my multiCSC firmware (tick re-partition, etc...)
My home network is Vodafone (CSC is XVF which is not part of my CSC).

If i got it right you are not root, right? if you are root there are other ways....
Yes you need the right CSC to make it work , in this case Vodafone XFV.
When you change to a different CSC is recommended to check re partition to adjust to the possible change in partitions
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930F/XFV/download/G930FXXU1DQD2/131635/
Download the firmware and extract the correct CSC from it , if you do not want all the vodafone stuff you could download and unbranded firmware and use the BL ,CP , AP from it and the CSC (XFV) from Vodafone and flash it all together
BACK UP FIRST .......

Yes, no root (for now). Will only root in a year when I get my upgrade on my contract.
Thanks, you basically confirmed what I suspected. Just needed a Jedi to point that out so I have peace of mind. I shall report back... :highfive: :good:

No problem mate.
Let us know how it goes
Hello,
Bought one S7 with a BIG discount at a local carrier and they also provided network unlock. The phone has a "generic" ROM but with custom carrier boot up logos and other minor things i want to revert to stock Samsung. My real question is that a friend also bought the same phone and flashed the BTU UK rom with ODIN and althought the phone flashed ok with stock ROM, KNOX was tripped and now he cant use S Health and other security related stuff.
With *#1234# i have:
AP: G930FXXU1BPH6
CP: G930FXXU1BPIN
CSC: G930FOPT1BPI1
With Phone Info i dont have multi CSC, only the one from the carrier (OPT)
Wich country ROM should i flash with ODIN to get the phone as stock Samsung and without tripping KNOX? My worries are warranty issues if KNOX is tripped…
Thanks a million!
Flashing stock does not trip KNOX, only flashing custom, so either your friend isn't telling you the whole story, or it was already tripped
You can flash any stock ROM with ODIN as many times as you want and it will never trip KNOX
BTU or XEU are both UK unbranded G930F ROMs
BTU has Oreo 8.0
XEU is still on Nougat 7.0 right now
Yeah, i talked to him on the phone 10 minutes ago. His problema was that he downloaded the firmware from SAMMOBILE and when he placed the AP in ODIN it complained about md5 something… he said that he deleted the md5 extension and the flash went forward. Then the result was KNOX tripped.
Can i flash BTU for Portugal? Can i flash directly from android 6 to 8?
Thanks.

Never heard of that happening before, anyway yes you should be able to flash BTU over portugal, as long as you use CSC and not HOME_CSC, flash all 4 parts, AP, BL, CP and CSC
And yes, 8 will flash over 6 as it replaces the whole OS, it's not an upgrade when changing CSCs
You might need to select "Re-partition" in ODIN 3.13.1 if it doesn't work normally
Make sure to use ODIN 3.13.1 for Oreo or the flash will fail
I will flash the latest android 6 with BTU CSC and then i will go further to 7 or 8 via OTA. Fingers crossed!

Why not just flash 8.0 BTU? Save a lot of time and problems that come with upgrades, anyway changing to 6.0 BTU you will still have to factory reset and use CSC so it makes no difference
Is BTU also compatible with S7 Edge?
Hello people, I hope you're okay!
I bought an used S21+ but it was not clear that the model I would receive is Korean (G996N). While I don't have any issues, it also misses the eSIM option (and probably Samsung Pay is not going to work in Europe). The eSIM option would be really good to have (SPay I do not care a lot).
I've been searching for an answer in regards to change the region and the responses are mixed and I am out of Samsung phones and firmware loop for a few years. Some say I can just change the CSC region using SamFW and that's good to go. Some say it will not work because my KOO CSC does not allow this change. Also, OTA firmwares are lost until I switch the CSC back (but, from what I understood, if I also change the firmware it would receive OTA normally).
Question: is it possible, nowadays, to just change Firmware and CSC to another region? My phone has an Exynos processor so it would have to be a firmware from Europe or Latin America.
I also understood it will not brick nor trip knox efuse, right?
Thanks a lot!
@angourakis Ok let me give you a clear response about CSCs. ALL Samsung firmware will let you flash a new CSC (as long as you use Odin). This has worked for me every single time.
You need to update your Android to the latest 13 and download and extract this (remember to use “direct download”, this website is the only one with a good selection of firmware) and use Odin (get 3.14.1 non patched) to flash the HOMECSC file (in the CSC slot).
Hey @traman124 thanks for the response!
Why this firmware in specific? I am running a more recent firmware than the one you mentioned. Also, do I need to have the bootloader unlocked?
Thanks!
It doesn’t need to be that version @angourakis it can be any version… that one will work though And you can use Odin with a locked bootloader (with download mode).
@traman124 thanks again!
Unfortunately, I tripped knox while trying to install a CSC from G996B version (kept BL, AP and CP from G996N and only used CSC from B version).
Now I am trying to look for a trade in program to replace the phone.
Thanks anyway, I really appreciate your help!
@angourakis I’m sorry….. this has never happened to me while flashing CSCs but the few times I have I did it with the same variant phone/tablet…..
