Which files to flash to update to latest firmware and keep provider compatibility - Samsung Galaxy S7 Questions and Answers

I have a g930f which originally had the TTT (Trinidad/Tobago) firmware. I am in the USA on AT&T. When I download the latest TTT firmware from Sammobile, which files in the .TAR should I flash, and which should I avoid? One of them at least would overwrite my AT&T compatibility I believe, but I'm not sure which one. Thanks for a reminder so I can update, anyone who can help!

Lost OTA updates after flashing other region firmware

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

Not receiving OTA updates

I have got an unlocked Galaxy S7 (G930F) and have flashed the android nougat update (BTU - UK - 7.0). It is working fine.
Since I have updated to nougat, there are some updates released (bug fixes, I can confirm this on sammobile site) but are not available when I check for the updates in settings.
Any idea on what this issue might be.
If you have either root or custom recovery you can't receive OTAs but you can update using SmartSwitch on your PC

hi mate
Updates ( if you are not rooted) are CSC carrier dependent , if your carrier or CSC do not issue any updates ...you will not have them.
When you checked in sammobile you checked if your carrier / CSC had updates?
No updates on Smart switch

I do not have root or custom recovery. I have downloaded the firmware from sammobile and checked that the knox warranty is not tripped over and the device status is still official.

The BTU firmwares in the UK are not network dependent as far as I know and they come installed in unlocked devices with no network bloatware.
I do remember flashing the CSC (G930FOXA1DPLT - that's the current one) which came with the BTU firmware. The new CSC has updates (G930FOXA1DQB1).
Am I missing something or is the device still dependent on a network to approve this.
Do you get any error?

No, it says "the latest updates have already been installed "
I even had this issue on Android 6 so I downloaded the Android 7 and flashed it via odin. Now there are updates but I would like to get the OTA to update it.

Are these bug fixes for the country AND the carrier you are using

Yes the bug fixes are for this country (UK).
I am not sure if they are carrier dependent as it is an unlocked software (I am on O2 and there is a different firmware for O2 locked devices).
Are they still carrier dependent is the phone is unlocked?

Okay, in this case I think I will have to wait for O2 to approve them.
I thought the idea of having an unlocked phone from samsung is to use any sim and get updates directly from Samsung when they release it.

Hi
You get updates either by the carrier or by the CSC , in your case you have an unbranded firmware , BTU, so no carrier updates...you will get an update only when an update for BTU unbranded firmware is release it , independently if there are other firmwares newer than yours around....only way to keep updated to the latests is flashing it yourself any new release , check this thread if you deciede to go that way
Try to get your CSC code by installing Phone Info from the market : I too have flashed the first official Nougat BTU UK 7.0 firmware with Odin, with a complete reset of the phone, but in my case I still have CSC = ITV and not BTU.
This seems to prevent us from getting the new OTA update : somewhere I've read that after the Odin procedure I should have entered recovery and factory reset the phone from there to get the CSV changed to BTU as the installed firmware is a "multi-csc" variant.
We still can download today's new firmware from SamMobile and use home_csc to avoid resetting again the phone.
Hope someone more expert than me can confirm/correct my statements

I was wondering the same and SergioA is right. I still have the DBT CSC although I was flashing the BTU Firmware. Thanks for clarification

So my S7(Sprint) running on G930U firmware will go back to Sprint Nougat firmware full of bloatware?

The BTU has a firmware update available on sammobile but not it's not OTA update on my phone.
What if I download the new update and flash it via odin with HOME_CSC file added. Will it start the updates by carrrier?

My S7 DUOS FD and my wife's S7 F both recieved the Nougat OTA update DQB1 today, mine was originally CSC XSG (UAE) and mi wife's was CSC TTT (Trinidad And Tobago), and both were updated to CSC BTU Nougat Final release, changing the CSC to BTU (this will wipe out your memory in the process but for a newer OS version it is recommended). I had doubts about getting any OTA updates since my S7 is the FD version which does not exists as a BTU phone originally, but in the end I got the update.
Long story short, if you want to recieve OTA updates after sideloading firmware with ODIN with a different CSC, you should fully convert to that new CSC, otherwise you won't get the OTA's.

Hi
if you have a DPLT firmware you should get it soon.....unless your system by some reason is not set as original ( even if knox is tripped but your system is set as original you will get it) anyhow is faster if you download it yourself and flash it , use home_csc so you will not factory reset your phone , NOTE: has to be the same home_csc that you have in your phone right now , not any home_csc for example:
Lets say you want to flash the latest firmware and it happens to be from France and you do not want to loose any of your apps , config or data
1 find out what CSC is installed in your phone ( phoneinfo app is great for that) in your case BTU
2 download the latest possible firmware for your CSC and extract from it the home_csc file , save it , discard the rest
3 download the latest firmware available , in our example France , extract from it download the MAIN-file and extract AP BL & CP save it , discard the other 2 files ( home_csc and CSC from France firmware
4 now take AP BL & CP from the latest firmware ( in our example France) and take the home_csc from a BTU firmware ( why , because is the CSC installed in your phone) and flash the together
In that way you can always have the latest in your phone without waiting for it , phone will not be knox tripped , will be 100%official as is all official firmware
If your using the btu version for UK phones, then how did you manage not to brick your phone? The UK phones do not have snapdragon, they have the Samsung chips.

Thank you, you are a hero :good:. I did update via odin and installed it without losing any data.
As I have said I have previously (about a week ago) used the CSC file rather than HOME_CSC.
I have the Phone Info app, The Orignal CSC code is blank(is it normal?), Does this look normal as I have not checked the CSC before updating to android nougat. I have added a screenshot of it.

A750F compared to A750FN ?

I'm wishing to flash Pie A750FN firmware into a A750F/DS phone via Odin.
Can these different model numbers take the same firmware?
I'm not familiar with this model (it's for a friend) and I am wondering if the firmwares are compatible.
The original CSC is XSG (UEA) and I wish to change firmware to either BTU or XEU (UK)
Would Odin accept this?
There will be no root involved, just stock firmware.
Any comments?
Thanks

I need help to identify the correct firmware for my S7 (SM-G930F)

I bought a new S7 (G930F) at ebay. When it arrived i wanted to update to the newest firmware, but i got an error notification.
I contacted Samsung and they told me to send it in.
They checked it and told me, that they are not willing to help because the phone is flashed with a wrong firmware. I bought it as a new device. This is unpleasant.
The seller doesn't answer my messages, so i thought maybe i can flash a new firmware by myself. The actual firmware is working but it is outdated. (1. August 2018)
But how can i find out which firmware is correct for this phone? How to say if it is exynos or snapdragon?
The phone information
Modellnummer: SM-930F
Seriennummer: 5AF94C0C
Buildnummer: R16NW.G930FFXXU7CRH2
Kernel: 3.18.71-14274519 [email protected] #1
Basisband: G930FFXXU7CRH2
Android 8.0.0
Samsung Experience: 9.0
I would like to flash the latest firmware and i want to use the phone in germany. Can somebody identify the correct firmware?
Thanks a lot
What does the phone say in download mode? The ROM can be modified to lie about the model and firmware, but download mode will tell you the truth.
If download mode says it's a G930F then it's Exynos, if it says G930U/V/T/A then it's Snapdragon.
If it is a G930F then good news is you can just flash whatever G930F firmware you want over top what's on it. If it's Snapdragon then you're a bit stuffed, you can't flash Exynos firmware onto Snapdragon.
For updating it if it is G930F my recommendation would be to find out the region code for your device, e.g. from here https://updato.com/firmware-archive...act=1&r=DBT,XEG,DCO,DDE,VIA,DTM,VD2&v=&rpp=15 then download the firmware using that region code with SamFirm tool https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Download Mode says SM-G930V
I'm doomed
Yep that's a common scam. If you can't return to seller the next best thing would be to flash the G930U firmware, which is the generic unlocked firmware for Snapdragon.
It won't give you the equivalent experience, but it will remove any bloat and give you a carrier unlocked phone experience.
You can use the same methods I mentioned to get your hands on the latest G930U firmware and update the device, but you may need this specific Odin version to flash G930U over G930V https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Thanks. Does TMK, TFN, TMB,... make a difference when the phone is used in germany?
Should i flash all 5 files:?:
AP
BL
CP
CSC
Home
I tried and my result is: Flashing only AP was not enough. Flashing all 5 worked fine for me. I chose TMK and even LTE is working. Thanks a lot.
Glad its working, for reference CSC and Home_CSC are both CSC files and you usually pick just one. Home_CSC doesn't do a data wipe, CSC does.
But when changing from G930V to G930U it's always safest to do the CSC wipe.
