Not getting ota updates

Hello guys
I have my galaxy s7 from germany. A while ago I flashed the btu software which had newer changelist. Now I don't know what csc my phone uses because I'm not getting the original DBT neither the BTU updates via OTA. You can see my phone info screenshots. How can I change my csc to get the ota updates?

Flash 4 files either BTU or DBT with the original CSC file instead of home CSC. It will wipe the phone but that's required so you get the OTA's.
I did that a few days ago for BTU and got a new OTA update today.

Okay thanks. Can you send me a link with all the files needed? Or some kind of guide?

Sure.
I downloaded BTU firmware from here. It's faster to download than sammobile and it's one OTA update behind so you can test the OTA works right away.
http://updato.com/firmware-archive-select-model?record=AF9CED1074D111E69B2DFA163EE8F90B
1. Download firmware above (or DBT). Extract/unzip to your computer.
2. Download latest Odin (3.1.1)
3. Set up a security pin on your phone, apparently it asks for this but it didn't for me, possibly because I didn't use home CSC but better to be safer than sorry.
4. In Odin allocate your extracted files to each check box(AP, CSC etc.). You don't need to change any settings on any other tabs etc. Make sure to use regular CSC not the home one.
5. Plug in phone, wait a while until detected and then you can start the process.
When complete search for OTA update before reinstalling all your apps. Should be a little quicker this way.

I might do something wrong but no change in csc. I set pin code. I set it as start up protection(without it as well), but no luck. Flashed the original csc my phone was wiped but still no ota and still the same screens in phone info as I posted earlier. I also tried BTU HOME csc but no luck with that.

Samsung is kinda late with the OTA updates so it might take some time before they push it to your device but you better of by making a backup of your apps and setting trough the sammy cloud and then flash the newer firmware in Odin.

Being in MM , download and install BTU MM Firmware (UK) using Odin ( it MUST be this one the BTU one), once youre done, check your software update and it will begin to download the nougat update , (around 1,2 GB) no matter where you come from (im from Spain), it will install automatically, then change your Language settings, and THATS IT !!, you have Nougat Official , without tripping Knox, and working flowlessly! ( IS FOR EUROPEAN EXINOS MODEL ONLY) , and requires a little knowledge using Odin and all that stuff!
you can download the last BTU MM Firmware from here: http://updato.com/firmware-archive-select-model?q=G935F&r=BTU&order=date&dir=desc&exact=1

- Back-up any data from your phone that you don't want to lose, Samsung Smart Switch is a great way to do that
- Make sure USB Debugging is enabled on your phone in Developer settings, it doesn't hurt to tick OEM Unlock as well ( this is most likely not needed but I'm unsure, so make sure it's ticked just in case)
- Download the latest official BTU MM software for G935F
- Download Odin 3.12.3 onto your PC
- Download Samsung USB drivers and install those on your PC
- Extract the BTU firmware using Winrar
- Connect your device to your computer
- Reboot your phone into Download mode by using Vol. Down + Home button + Power button when your device is off, then press Vol. Up
- Make sure your device is recognized by Odin
- Select every file that has been extracted from the official BTU firmware and place them in their respective slots (Make sure that you use the regular CSC file instead of the Home_CSC file, this will wipe your data so you make sure you've backed up your files!!)
- Before you start, make sure that Re-partition is un-ticked in Odin, you can check this in the Options tab.
- Click start and let it do it's work.
After that, you can set up your device as you like, or just immediately go to settings and "Check for updates", then it should download the official update to Nougat right away.
Hope this helped!

how do I copy stock image/rom s7(snapdragon)

I am buying a new cricket wireless galaxy s7(snapdragon) and to fix the one I messed up. I want to know how do I copy the stock image/rom from the new s7 and put it on the old s7. Obviously they are both snapdragon models and they are NOT ROOTED. My old s7 just reboots and reboots I can get to recovery mode and the download mode. It only boots up to the samsung galaxy s7 screen before it reboots again and again etc. the reason is because I tried to root it with the tutorial on the unlockr's site the name of the article is "how to root the samsung s7 & s7 edge (all snapdragon versions) (video)" rooting the snapdragon s7 which broke my phone so all it does is reboot. Any help with backing up my new s7(snapdragon) and uploading the stock rom/image to the old s7(snapdragon) would be greatly appreciated.

Did you try downloading an image of a stock rom from updato.com or samfirmware etc.?
If not, download it, aswell as ODIN 3.12.3 and do a complete reflash (BL,AP,CSC,CP with re-partition checked, it includes a loss of data though).
You could try AP, BL and CP only and don't tag repartition, which won't wipe your device, if you are interested in your data. If you extracted your data, a full install mentioned above is recommended though. Just to get back to a clean image and anything your root might've messed up.
It should revive your old device and you probably don't need to buy a new one. Especially if i read correctly, just for extracting a stock image, which can be found on the internet already.
Given that you might already have triggered Knox, which will probably void any warranty from Samsung, you could try re rooting or leave it stock, which should be running good on Snapdragon still.

For other G930AZ Cricket Users I went through the samething. I used odin to flash the Engboot and then the phone just kept rebooting. To fix it I did the following.
The first step is to get the G930AZ stock image using samsung switch Here.
NOTE: Using the samsung switch Emergency Software Recovery to return to stock did not work for me, but I was able to get the stock firmware from it.
The model number is SM-G930AZ.
To get the serial number (took me forever to figure this out) go to the download mode on your phone (hold the power, volume down, and home buttons) and press the home button. The S/N is the serial number
After getting the firmware flash ONLY the BL, CS, and CSC (leave out AP) using this version of odin
http://www.mediafire.com/file/2t2sjqxtogbkafk/odin_3.12.3.rar
If that successfully flashes then things are looking good. The phone will restart and probably still boot loop but thats ok. Go back into Download mode but this time Flash the BL, AP ,CS ,CSC (Include the AP). IT should flash successfully and everything should be back to normal after that.
I was able to repeat this process twice with my G930AZ cricket phone so hopefully it works.

G9650 (Snapdragon) CSC Change/ Stock firmware change (NON ROOT)

Hi everyone,
Recently I flashed a stock ROM on my SM-G9650 and wandered around quite some time before gathering all the information to flash the firmware. Now I’m here gathering most (if not all) the information anyone might need to flash stock firmware to your device. This method does NOT require root and does NOT trip KNOX
First of all:
-Disclaimer-
I will not be responsible if your device gets bricked. PROCEED AT YOUR OWN RISK. This is a guide, and even though its pretty straight forward, stuff happens.
Now, onto flashing the device:
A few prerequisites prior to flashing the device:
- ODIN (latest): https://odindownload.com/
- USB Drivers for Samsung: https://developer.samsung.com/galaxy/others/android-usb-driver-for-windows
- An ORIGINAL Cable for your device (Preferably the one that came with it).
- WinRAR or 7zip
- A backup of your data (Optional)
- Patience and time
Ok, now onto the flashing:
First things first: this is a guide for the G9650 (Hong Kong) Variant with UNLOCKED bootloader. If your device model is different, find a thread according to your device.
1- Go to: https://www.sammobile.com/forum/threads/40735-Galaxy-S9-G960-multi-CSC-pit-language , and find the correct Multi CSC for your country/Region. (I live in the Caribbean but chose to use ZTO because it has LTE+ and VoLTE, and the only bloatware is Word, Excel, PowerPoint, LinkedIn and One Drive.). Once you find your CSC, head over to https://www.sammobile.com/firmwares/ and download your desired Firmware. Here is a link for CSC code meaning: https://www.androidsage.com/2017/07...specific-product-code-csc-and-country-region/
2- Once downloaded, create a folder on your desktop and move the zip file to it, then extract. (You can choose any folder you want, I recommend desktop because it is easier to find)
3- Install the USB Drivers previously downloaded.
4- Reboot your pc (By actually opening windows and clicking reboot.)
5- Open Odin and search for the folder you placed the Firmware in.
6- Load BL, AP, CP and CSC (NOT HOME_CSC) onto the correct slots.
Now onto the phone part:
1- Unlock your phone and go to Samsung switch.
2- Back up your data. (If you do not have personal data, then skip)
3- Factory reset the phone, through the settings option.
4- Wait for the phone to boot into the welcome screen.
5- Turn off the device
6- While holding down the Bixby button and the volume up, press the power
7- When the Samsung logo shows, let go of the power and Bixby buttons. Keep holding the Volume up button until you boot into recovery.
8- With the navigation keys, factory reset the phone, once completed, wipe cache and data.
9- Turn off the device.
10- Turn on the device while holding down the Bixby button and volume down. Once the Samsung logo shows, let go of the Bixby button. Keep holding the volume down.
11- Once in the download mode (blue screen with an android), let go of the volume down. Press volume up to select download mode.
Back to the PC part:
1- Once the device is in download mode, connect it via cable and wait for ODIN to recognize it. (a blue box indicating COM port is the indicator that ODIN has recognized the device)
2- Since the BL, AP, CP and CSC have been loaded onto the correct slots, and the device is connected and recognized, go into options and make sure that Auto Reboot and F. Reset time are checked.
3- Press start and BE PATIENT AND CAREFULL, Flashing a firmware takes time. If your cable breaks connection with ODIN, YOU MAY brick your device.
4- Once completed, your phone will boot up on its own, reboot it manually.
Congratulations, you have just flashed a stock, almost bloatware free Samsung Firmware.
If you have any question, feel free to ask.
- To Mods and Admins: Forgive me if I break any rules, this is my first thread. Just let me know what went wrong and I will fix it ASAP

You might want to consider changing the links you have posted for Odin - The latest version is 3.13.1 - The xda link has Odin 3.10.6 and the first Odin link has 3.12.x
Sammobile.com is one of the more reliable sources for Firmware & They conveniently have a link to Odin 3.13.1 as well..
XDA also has a link to the latest version of Odin here:
https://forum-xda--developers-com.c.../odin-available-3-13-1-oreo-fws-t3755957/page
It's strongly recommended to use Odin 3.13.1 to Flash Oreo Firmware ??

The link i posted has ODIN 3.13.1, when you open it in the browser (request desktop site on mobile), under the first image is the button for it. I used that link and said (Latest) so that when you head there you get the latest odin. Also, the link for the firmware is sammobile . I now see that its not very intuitive so i will add the link for the firmware (just have to type the device model and download the desired firmware. Thanks for the heads up

I have been out of the Android game since the S7 Edge. I just swapped from iPhone 8+ to a S9+ and love it so far. Question I have is which firmware can I use to debloat my S9+? It's on T-Mobile and I dl the stock firmware from the posted link but I don't think this is the debloated firmware. Any help would be appreciated as I don't know what all this CSC stuff is.

I would highly recommend searching the forums for your variant since it is a Snapdragon and probably has locked bootloader. This guide is for G9650, even though the process is basically the same.

I'm familiar with how to flash with Odin but just don't know what debloated stock ROM is compatible.

I don't see a section dedicated to just the T-Mobile version on the S9+.

Make sure the downloaded model matches your device model. For a US variant its pretty hard to find one since most (if not all) put some kind of bloat on them. Search for: Bloat free firmware g965U, and look around.

I bought an unlocked s9+ from ebay and later found out that its country sale came from Panama. My canadian GSM network does work on the device, but certain apps like samsung members show spanish promotions or samsung pay not being available.*
Can the csc code and country be changed in this case so i am able to get the canadian setting and access.

JULY Security update for ZTO (G9650) now available

Just bought a used unlocked AT&T Fold 2, how difficult to flash TMobile Rom?

The phone is working fine, calls, texts, even 5g. But I'm not getting any updates. It's still on Android 10 and One UI 2.5. I went to Samsung Members and wasn't given the opportunity to update, or join the beta, and when I go to Updates, it say my phone is up to date. I also tried to update with smart sync, but it also said my phone was up to date. I did a little research last night in the thread on how to flash, but it seemed kind of confusing. My phone says it's a SM-F916U, but I'm not sure which rom to flash. I'd really just like to get rid of the At&T branded apps, and be able to get OTA updates. Is this possible? I used to flash roms all the time on my S6 and back in the PPC days, but that seemed pretty straight forward. Since this phone is used, I obviously cant return it if I mess something up.

Download an app called Frija, along with the patched version of ODIN from here.
You can either flash unlocked firmware, or T-Mobiles firmware.
If you decide to flash unlocked:
In Frija choose manual, enter the device model as SM-F916U1
CSC : XAA
PDA : F916U1UEU1DUCI
CSC : F916U1OYM1DUCI
Phone : F916U1UEU1DUCI
Then click check update, then download.
If you want TMobile firmware:
In Frija choose either auto or manual. Enter the device model as SM-F916U and click Check Update, then download.
If you choose auto make sure the CSC says OYM in it somewhere, because if not it will download the Thom Brown edition frimwarr.
If you chose manual enter these:
CSC : TMB
PDA : F916U1UEU1DUCI
CSC : F916U1OYM1DUCI
Phone : F916U1UEU1DUCI
Then click download.
Open ODIN and put in the files in the respective places (BL, AP, CP, CSC, USERDATA if you downloaded TMOBILE firmware), turn off your phone, hold the volume up and volume down button and plug your phone into the computer.
after that it will boot into a blue screen, then you click up volume up to continue.
In odin make sure something shows up under ID : COM and when it does click Start.
Don't mess with the phone when it starts because it could be bad if it unplugs or anything similar happens.
After several minutes ODIN will say PASS in the top left, and from there on you can unplug your phone.
It will reboot, and take 5-10 minutes to boot.
Should be all done after that though so let me know if you have any questions.

Oh man, thank you so much for such a detailed response! I actually went to a Samsung experience store and they updated me to a stock AT&T android 11 build. The phone is working great, but I obviously don't want to have to go there every time there's a new update. So in other words, I'm still very interested in instructions on how to do this, so thank you again for that.. You've been a tremendous help, but before I start, could you possibly answer 2 more questions?
1. Is there any advantage either way of going with t-mobile or unlocked?
2. Does Odin back anything up in case I mess up somehow, can I get back to where I am now? Back in the PPC and early android flashing days, I remember it was essential to back up with recovery and or twrp.

Download an app called Frija, along with the patched version of ODIN from here.
You can either flash unlocked firmware, or T-Mobiles firmware.
If you decide to flash unlocked:
In Frija choose manual, enter the device model as SM-F916U1
CSC : XAA
PDA : F916U1UEU1DUCI
CSC : F916U1OYM1DUCI
Phone : F916U1UEU1DUCI
Then click check update, then download.
If you want TMobile firmware:
In Frija choose either auto or manual. Enter the device model as SM-F916U and click Check Update, then download.
If you choose auto make sure the CSC says OYM in it somewhere, because if not it will download the Thom Brown edition frimwarr.
If you chose manual enter these:
CSC : TMB
PDA : F916U1UEU1DUCI
CSC : F916U1OYM1DUCI
Phone : F916U1UEU1DUCI
Then click download.
Open ODIN and put in the files in the respective places (BL, AP, CP, CSC, USERDATA if you downloaded TMOBILE firmware), turn off your phone, hold the volume up and volume down button and plug your phone into the computer.
after that it will boot into a blue screen, then you click up volume up to continue.
In odin make sure something shows up under ID : COM and when it does click Start.
Don't mess with the phone when it starts because it could be bad if it unplugs or anything similar happens.
After several minutes ODIN will say PASS in the top left, and from there on you can unplug your phone.
It will reboot, and take 5-10 minutes to boot.
Should be all done after that though so let me know if you have any questions.

I've never seen a thorough response to a post in a long time. I haven't been to XDA in a while, so it's nice to see that it hasn't changed.
@zimgir124 Thank you for such an awesome post. Like op, I also have an unlocked AT&T branded Z Fold2, so after reading this post, I'm soooo tempted to flash the unlocked firmware. haha

I tried downloading the T-Mobile manual but I dont get the download button enabled when I enter all the info you mentioned above. When I try auto for TMB I dont get the OYM CSC. I tried flashing the unlocked firmware but now I am not getting 5g on tmobile SIM.

Fixed. Got it working. Thanks
