So I downloaded the latest XSA update which came out yesterday on SamMobile, and flashed all four files - only to find that my phone had been wiped, including my /data partition :'(
So my question is - what are the four categories of files to flash in Odin (AP, BL, CSC, HOME)? And which one is responsible for me losing my data?
If you flash CSC will wipe your data. If you flash CSC_HOME will not wipe your data.
AP: is your system partition with recovery and stuff.
BL: your bootloader
CP: your modem
CSC: this is what features you get in some countries or carriers like Wi-Fi Calling.

Thanks for that. So can I flash the CSC file under CSC_HOME?

Yes. In the CSC slot you put the HOME_CSC file

And if the CSC is the same, I can just omit this file?

No, you must always flash the 4 files!
If your CSC is XSA:
AP, BL, CP & HOME_CSC_XSA
Then your data will stay intact!
Note: this can only be done if you stay at the same CSC; if you want to change your CSC for any reason, you need to flash CSC-file of the new country/region (that will reset your device)
Re-partition?
Do I have to enable the "RE-PARTITION" option in ODIN when changing CSC?

Hi mate
It is recommended , changing to a total different CSC may need a change in partition size...

Mix and match?
Just wondering, could it be possible to mix and match?
Example: Flash the AP of T-Mobile and the CP of AT&T? To avoid incompatible band problems

Hi
For what I understand all USA ( Snapdragon) versions are compatible , so that would possible BUT to be sure you should ask in the right forum , this is for the international version Exynos
What is the UMS
What is the UMS part of ODIN?
EVERYONE HAVING PROBLEMS TYPING EXIT
Before typing "setsid su<enter>?, type the following: "alias a='exit'<enter>" and THEN type "setsid su<enter>".
IF you do this, you can exit root shell by just "a<enter>", which is cake easy to do.
i made a mistake
cancel

Read some threads, the instructions are literally everywhere, they are even under the download on sammobile site, which means you have not read anything
Better off using odin.
BL FAILED

Download XEF firmware for your phone, and flash all 4 files (BL, CP, AP and CSC). It should go back to normal state.
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.

My phone CSC was Rom and I flashed HOME_CSC instead of CSC will I still get OTA updates regarding the btu firmware?
Short question:
Can I flash G930T firmware into a G930AZ Galaxy S7? Have someone tried or accomplished this? If so, how?
Explanation:
I have a cricket wireless branded Galaxy S7, since cricket does not seem to have any interest in releasing android 7 nougat anytime soon, I decided to flash another firmware...
I was planing on using the G930U, but since that one is not available either, I resolved to put up with T-mobile's bloatware;
I tried:
To flash all 4 files from T-mobile's firmware on ODIN
Result: I got an error saying the ext4 file was too big, the device got soft bricked and stuck in a bootloop to recovery, I had to factory reset using the G930AZ files on ODIN
Only the AP file
Result: Same as above
I've read in some forums that I should try to enable the reformat option so it wipes all and creates the partitions with the right size and while that makes absolute sense I don't want to end up with a $600 paperweight.
There's the NAND Erase all option, Flash Lock, T Flash, Phone Bootloader Update and Phone EFS Clear.
Also, I was wondering if it was possible to mix and match files, example: flash the AP file from T-Mobile's Nougat while keeping the CSC and CP of Cricket (CSC: Cricket does not support Wi-Fi calling, CP: To avoid problems with unsupported bands)
I have the BL, AP , CP, CSC files of both the cricket's Android 6 and T-mobile's Android 7.
Thanks you in advance for your time and effort in answering
You should consider on using .PIT file along with others.
Therefore you will remap your partitions to match filesystem sizes.
But I must warn you: do not mess with the partitions if YOU DON'T KNOW WHAT YOU'RE DOING.

If I use the latest version of ODIN do I still have to get the PIT file? If so, where do I get the PIT file from?

In theory it's inside one of the .MD5 files you must use in ODIN.
Try to download official trusted firmware package source such as one from sammobile.com or updato.com and follow the instructions to flash it

Any update on this? I'm in the same boat and want to flash T-Mobile rom to G930AZ.
hi
i root my phone XSG(SM-G935F) s7 edge with CF-Auto Root and my phone is dead means its only showing Samsung logo(Boot Loop). not even booting in safe mode and i do the factory reset after that my phone turn on. but now some apps(like s7edge feed) is not working(root failed)
root-checker shows its not rooted
is there any special root file for different country's like.... root file for xsg ROM ?.
i used this one to root - CF-Auto-Root-hero2lte-hero2ltexx-smg935f
Now i want to go again in stock ROM. I downloaded ROM zip from sammobiles and when i unzip it theres 5 files
like :-
AP
BL
CP
CSC
HOME_CSC
SO MY QUESTION IS is that i can flash AP only ? OR
DO i must flash 4 files together ?
currently after flash the root file my phone edge feed is not working
after all everything working fine not including the software update
so what should i do ?

Hi
to your questions:
CF Autoroot as far as i know is not working correctly on Nougat you have to root with TWRP and SuperSu or Magisk zip file
Flashing , as you do not really know what happen during rooting I would flash with all 4 files AP ,CP, BL and CSC or home_csc ( if you want to preserve your data and avoid factory reset use home_csc BUT it has the sama as the one you currently have installed)

You don't have to update via OTA, you can do a Google search for firmware updates for your model number then download any available updates for your specific model number then flash thr update(s) via Odin.
