Questions regarding Odin flashing and changing CSC

Hello and thanks for looking at this thread! I am a longtime Android user and have recently switched from Note 4 to S7. The Note 4 was DBT so I had no doubts about flashing and before that I had a Nexus 4 that was a breeze to update via fastboot or TWRP.
I got my phone from a carrier Vip Mobile in Serbia (CSC TOP). Since the latest software update is from August, I would like to switch it to BTU in order to get all the security patches and prepare the phone to get Nougat in a timely fashion.
Here is detailed FW info:
Model SM-G930F
Model name Galaxy S7
Country Serbia (VIP)
Version Android 6.0.1
Changelist 8888212
Build date Tue, 09 Aug 2016 09:46:20 +0000
Security Patch Level 2016-08-01
Product code TOP
PDA G930FXXU1BPH6
CSC G930FTOP1BPH1
I have a couple of questions to experienced users:
1. Is it enough to just flash bl, cp, ap and csc? From what I read, there is no more need for pit files since they are incorporated into CSC. For older models like S6 Edge I had to use a pit file to switch from carrier to DBT fw.
2. If I decide not to use OTA later, am I right in understanding that I can just flash the AP file and keep my CSC and Data? The reason I'm asking is that on the Note 4, there were sometimes radio problems if you flashed the ap without the corresponding bootloader and radio.
3. Were there any feature and stability updates between August and December that you noticed or were they just security patches?
Any input from people that are experienced with Odin or switching regions is higly appreciated. I am sorry for the long post but I would like to give all the pertinent information to best understand the process. Thank you all in advanced and happy holidays!

If you are about to change the CSC you should do it the following way:
Download and flash the new firmware. Put AP, BL, CP and CSC (not home_CSC) in appropriate places in Odin. Do not change the default settings in Odin. The CSC contains the pit file needed to partition the memory right. Always flash all the files, do not flash only one file and you are more unlikely to run into problems. If you in the future want to flash an update with the same csc as already is on the phone, you can then use the home_csc and this way you will be able to keep all data and it will be just like an OTA update.
After the flash boot into recovery (vol+, home, power) and then delete cache partition and after that wipe data/factory reset. Then reboot. This is important as this step will set the csc to the new default csc of the newly flashed firmware. Unfortunately, there is no way to choose csc if it is a multi-csc firmware, it will set the default csc for this multi-csc. I think that the BTU is a single csc firmware so in this case you are good and the phone will pick up updates OTA for the BTU in the future.
I changed the csc of my S7 and before I had made the last steps into recovery my phone did not have a csc at all as I checked with Phone Info. The csc fields were simply empty and I would not have been sent any OTA updates after this. I got this important step from Greenman at the SamMoble forum.

Thank you for the great guide! I guess I will then wait a bit for Nougat to start rolling out. Based on Note experience I would like to do a factory reset at that point anyway because of the major changes.

DBT region receives firmware with OXM multi-CSC, which also includes TPH CSC (Portugal), so there should not be any issues.

Flash
I loaded the .tar files into Odin.
Auto Reboot is checked.
F.Reset Time is checked.
Everything else is unchecked.
After my phone boots into download mode do i have to press anything on it or i just press start on Odin ?
The only phone that i have flashed was my Galaxy S in 2010 and i haven't done anything like this before.

If I do this, will I receive ota updates in the future?

Use HOME_CSC not CSC, however, if there would be any issue during the upgrade, the storage would show only 16GB and you would have to do a factory reset anyway. If you are going to try to do the upgrade, I strongly recommend backing up your data.

Yes, the firmware for any regions included within OXM multi-CSC is the same.

For variant G950FD i neeed to use this same firm, right?
EDIT: i did this method and works fine. But the baseband was not to be CRB7? My phone says baseband G950FXXU1CRAP and the compilation number said R16NW.GF50FXXU1CRB7. Does its good?

Yes, that's right. Samsung did not update modem firmware or CSC package. Only bootloader and AP (system) were updated.

I flashed Oreo CRB7 final build from Germany and everything is great. But notifications for viber doesnt work as supposed. When i snooze them for only 15 minutes they never appear again and even after 2 hours when i open viber app i have new messages for which i didnt get notification neither sound and stays like that. But when i restart phone everything becomes normal untill i snooze some notification again. I did clean install, clear cash twice and factory reset the phone before Oreo.
Followed the instructions from this site step by step (it was flashing with extracting .lz4 extensions). Help?

Rooted G930F update w/o messing up CSC?

Hi,
I've a G930F stock rooted with TWRP and SuperSU. The phone has the DBT (Germany unbranded) CSC. I'm looking for a "least effort" way to update it with Odin w/o having to restore data all the time.
What I tried:
Flash whole stock firmware (AP, BL, CP, CSC (not HOME_CSC))
reboot right back into download mode
flash TWRP
Boot into TWRP
Flash SuperSU
Reboot phone
This works at a first glance, but messes up my CSC. Apparently the DBT CSC is a multi CSC, containing DTM (Germany T-Mobile) as well. My phone has some T-Mobile specific configuration entries and CSC-dependent stuff like entering *#1234# in the phone app to get the CSC no longer work.
What does work:
Flash whole stock firmware (AP, BL, CP, CSC (not HOME_CSC))
Reboot phone
Phone now does a factory reset and encrypts /data
Reboot into download
Flash TWRP
Reboot into TWRP
Format data and restore data backup
Flash SuperSU
Reboot phone
Afterwards the update is complete and the CSC is good. But I'd like to avoid the additional steps.
When searching in the forum I got the impression that flashing the HOME_CSC instead of the CSC might be the solution in my case. Can anyone confirm this?
Where exactly does the G930F store the "active CSC" in case of a mutil-CSC? Apparently my short way to update the phone destroys that information.

@Vardion
I wonder if you got your problem solved?
I happen to have the same firmware as you and also want to manually update - since I got twrp and Magisk, Sammy withholds the security updates for me.
As Roberto W. pointed out to me flashing only the CSC_HOME.... from the downloaded firmware should do the job. The same information actually appears at the SamMobile site which states in Point (2) to the right:
Add each file to it's respective field in Odin v3.13.3. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.​
Do let me know how things worked out.
Cheers!

Method of installing the Official Android 8.0 on your S7 Edge/S7 (SM-G935F/SM-G930F)

To install it, simply download the firmware file from the official Samsung firmware section link that is given below and then use this new version of Odin that you can download from XDA.
Here are the link:
Oreo Firmware for S7 Edge (SM-G935F):*
https://www.sammobile.com/firmwares/...U2ERD5/217550/
Oreo Firmware for S7 (SM-G930F):
https://www.sammobile.com/firmwares/...U2ERD5/217727/
Odin Version 3.13.1:
https://forum.xda-developers.com/gal...o-fws-t3755957
Download the firmware as based on the model number of your device (i.e. SM-G935F / SM-G930F) and download the odin file.
Turn on your device in download mode and then connect to your PC. Run the Odin and select the based on the sections given in it (i.e. BL, AP, CP and HomeCSC).
After selecting these files click on the start button and let it complete. After completion your device will restart several time and you are done with installing the Official Oreo on your device that won't trigger the knox.
Enjoy!

Question help: SM-a125U stuck in Hash of data does not match digest in descriptor

Previous android version: Android 11
Previous base-band version: A125USQU2BUG5
company: wireless cricket
In the context of flashing with the new firmware I used :
- Odin version: 3 v3.14
- Firmware used: Samfw.com_SM-A125U_USC_A125USQU2BUL1_fac_2

The error is related to the vbmeta check. Did you used a sock firmware or you have patched it with magisk? Btw i reccomend to use frija to download the firmware.
If i can suggest I would make this steps:
1) download latest firmware with frija
2) Flash the stock and see if it work
Otherwise if this not help:
1) download latest firmware with frija
2) patch the whole ap and not only boot.img with magisk
3) open odin and flash it using the patched ap on the ap slot
If nothing above works, I think you can try this... not sure it will work. Replace inside the ap the vbmeta.img with the attached one that have the disabled verified boot.

Thanks for the reply.ok
1- The firmware is stock.
2- I didn't patch any of the files I got ( any recommended guide on how to proceed>?)
3- I' so new at this
But anyways, yesterday I kind of sorted out the stuck by adding BL file, and CSC file along the AP file to ODIN, the phone restarted ok but found out it hasn't been unlocked from the carrier yet, so I guess that by judging what u just said, there are few thing I need a guide to
- Flashing the stock
- Patching the AP file
Ps Frija opens up when executed, but it closes in less than 1 second. (Pc 's OS: win 10 enterprise 64 bits)

When you flash with Odin you always need to use all the files provided on the stock firmware ap, bl, csc and cp. If u are upgrading you can use the home_csc instead of the csc file that will let you keep your data.
Are you sure you have installed the framework that Frija need?
For the ap patching, is only meant if you want root your phone, flashing the whole ap instead of the boot.img only will let you fix the vbmeta checks too.
Install the magisk app.
Open it and tap Install, it will ask for a file to patch, chose the ap file of the stock firmware you downloaded.
Final step, flash ap patched and the others (bl,csc,cp).
When you say unlocked by the carrier what do you mean? You have any sort of sim block? Or you only want remove your carrier apps and configs?

Mannn thanks!
I rooted my tab 5Se a long time ago and deleted the firmware files except the AP.
I got stuck on the same screen today when I re-locked my bootloader after a stock AP-only flash
Then I saw your reply here and got the rest of the files flashed and it worked and booted
And for those who are reading if you don't have a SIM on your tablet you don't need a CP that's why you won't find it in your firmware zip file
