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

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.

Flashing stock rom with odin / sw rev. fail

Hi, I recently tried to get my phone unlocked. I watched the guy do it, he flashed an older modem and then flashed a UAE firmware.
My original is O2 UK, and I'd like to revert to this firmware as the About Device section shows up with Unted Arab Emirates and the mobile networks section shows LTE rather than 4G.
I have tried flashing the latest revision of the O2 stock rom and odin fails attempting to write sboot.bin with the error message SW Rev. fail (I don't recall the exact numbers after this) appearing on the phone.
I am guessing this is the secure boot loader, which I am aware you can't downgrade, but is there any way of flashing this stock rom since I know it is compatible with the phone?

Try to flash G920FXXU5DQA7 (CSC code:BTU)

You could possibly use smartswitch if you have the serial number of the phone which would download the default firmware that the phone came with if odin fails again

Yes i agree, smartswitch could be your best option.

Thanks for the suggestions. Tried Smart Switch, same error. It appears on the phone as sw rev. check fail.
What exactly is the problem here? Is it that the installed firmware has a newer bootloader than the most recent O2 firmware? In which case is there any way around it?

Yeah looks like this is a bootloader issue, it won't let you install a firmware which contains an older bootloader, only thing I can is to download the latest non branded UK firmware and see if that flashes.

I'm getting this error too with Device 4 Binary 3 but i didn't find the right firmware yet
I hope in Nougat release

Samsung updated their bootloaders to 4XX in September/October so you cant flash back an older one or downgrade,so the only solution you have is to flash the new one which is 5XX released this year.

Change Galaxy S7 CSC

Hello, i'm trying to change my DBT(germany) CSC with UK one but even if i flash with odin last uk firmware with repartition, every time phone restarted main language and CSC doesn't change. How can i align product code, CSC and firmware?
Thanks

I had the same problem. After 8 unsuccessful attempts I was able to change CSC. But I had to flash ETL ROM and after that I was able to flash BTU. DBT and VDC/VD2 are nasty multi CSC.

This means you have to root the phone right? Can it be done without rooting?

I did not root me phone. CSC can be changed, but it's challange for VDF/DBT firmwares.
As I said, after 8-9 attempt I achieve to change CSC (also had custom status v DN mode).

Hi XDA community,
I have a stock S7 Edge, which now has the XSG CSC (UAE). I want the XFA CSC (unbranded South Africa).
Problem is XSG and XFA are part of a multi CSC (OJV). Everything I've read says this can't be done unless I root my phone which I'm unwilling to do for now.
I'm sure there's a smart someone out there that has figured out how to do this!

You CAN flash the VOD-firmware, but your CSC will change to the "default"-CSC of the "Multi-CSC OVF" -> VD2
You must use the AP-BL-CP & CSC_OVF of the VOD-package -> it will reset your device (which is necessary)!

Use the patched version of Odin. Just search Google for "patched Odin" & you'll find it. However, if you use the G955W version of the firmware, you'll lose several features of your phone. For example, the G955W firmware disables the FM Radio. Good luck.

Thank you so much friend, i will sure try it and let you know.
You know i don't really use radio and the main reason to switch is because i don't get OTA updates, anti malware in device Maintenance's won't activate, and i couldn't install certain samsung apps like samsung members and samsung+
Thanks again
