I have a S7 Edge from Rogers Wireless (Canada) and they are painfully slow with updates- I was still on the Apr security patches (APD3). I found the firmware for the July update (APG1) which I downloaded (same CSC code -> RWC.)
Used ODIN, defualt settings, with all 5 files chosen in ODIN - followed the guide on XDA and ended up losing all my data.
Is there a way to install these "updates" without losing everything?
Thanks!
Did you used the normal CSC file?
With the HOME_CSC you shouldn't lose anything.

I used the CSC file that came with the package- (HOME_CSC_OYA_G935W8OYA1APG1_CL8421152_QB10225351_REV00_user_low_ship.tar.md5)
Is it possible to use ODIN and just use the AP file, and ignore the CSC/BL/other files- would that enhance the chances of not losing data?

you only need to flash 4 files, you flash the csc twice the second time was not needed and you erased all your hard work.
the files you need were BL, AP, modem and home csc only not the other csc file.
If you read the instructions carefully it tells you to make a back up so that you can restore your phone in case of problems.

Thanks Cosmic.
Yes the mistake was in using the regular CSC (instead of the home CSC.)
If I now want to change my CSC (Rogers RWC -> Fido FMC), can I flash just a single home_CSC file?
Or,
1. Can I flash the full CSC file (since it's a major change.)
2. Flash the 3 other system files as well, and then home_CSC.
Thanks.

How to flash the firmware (5 files in archive) to your s7edge?
AP, CP & BL I understand, but the 2 CSC-files...?
CSC -> there's a PIT inside and will wipe your device
HOME_CSC -> the data should stay on your device
Today I tried to update with HOME_CSC, everything was OK, but at the end Odin 3.10.7 FROZE at "meta-data" (this folder is in the HOME_CSC file): nothing happened anymore and I had to pull the cable
Smart Switch didn't recognize my S7edge anymore for the "Emergency Firmware Repair"!
Luckely, Odin did recognize my device and could install the firmware with the "normal" CSC-file and afterwards my device was reset...
I hope someone has a solution on this, because I don't want to install everytime again and again...

Well, the flash went just fine. No problems except the device reset at factory settings. As brand new one....
But of course I would like to know how to flash without resetting the device.
I had the same problem yesterday when used Home_CSC... flashed again with normal CSC and went back to normal with a formated user data
We really need a solution to that... What would happen if we skipped the CSC file when flashing thru ODIN?
Flashing with CSC and not home_CSC will also reset your CSC.
Eg: I was on VODAFONE Romania and flashed stock unbranded using CSC. The result was I lost my ROM (from Romania) CSC, and defaulted to XEO from the multi CSC.
In this situation you cannot go back to your original CSC even after flashing using Smart Switch.
Rooting is the only option then and that will trip Knox.

anybody figured this out?
Just had the same problem flashing with HOME_CSC it got stuck in ODIN and had to pull the cable.
Had to turn off phone and boot again in download mode to flash again with a straight CSC.

CSC contains an instruction that allow Odin to wipe the DATA
Code:
--update_package=CACHE:recovery/sec_csc.zip
--carry_out=csc_factory
--wipe_data
HOME_CSC contains instruction only to allow wipe of cache BUT the original HOME_CSC can cause Odin to freeze at the end of the flashing process.
Code:
--update_package=CACHE:recovery/sec_csc.zip
--carry_out=csc_home
--wipe_cache
That's why you need to modify the HOME_CSC using the CYGWIN tool.
Just dont flash the home csc. I never did it. Everything work greats.

HOME_CSC is supported on Odin version 3.11 or later. It's okay to flash it now.
Sorry to revive this thread but when a downgrade is done from Nougat back to Marshmallow a factory reset via recovery must be required if flashing HOME_CSC. Otherwise just use normal CSC on downgrade.
thank you
Samsung S6 Active G890A
Hello,
Where do I find a HOME_CSC file for Samsung S6 Active SM-G890A device?
Hi
As my country haven't gotten the latest update, I decided to download it through SamFirm (official firmware from Samsungs servers, just not capped in download speed like Sammobile).
But the thing is, that after decrypting, it's giving me 5 files and not just one .tar
The first 3 are named AP_xxx, BL_xxx and CP_xxx so it's pretty easy to guess where I should but them. But the last two files are named CSC_AUT and HOME_CSC_AUTO, so which should I use in the CSC slot?
Also, the UMS slot is greyed out, after putting one in the CSC slot and is stating that the firmware is only filling 65mb, even though it fills 1.8gb.
Anyone know what to do?
Thanks in advance
Hi,
Direct quote
"For some reason Samsung are now providing 5 files.
You now have some options:
1. If you want to keep your existing set up and just update, or reinstall existing firmware, you are better using SmartSwitch as described here:
http://www.sammobile.com/forum/showthread.php?t=29918
2. If you want to keep your existing set up, but want to install firmware with Odin, then use
BL - Bootloader
AP
CP
CSC_HOME
3. If you want to install another country firmware, or wipe your phone, then use
BL
AP
CP
CSC
CAUTION: This CSC contains a PIT file that will wipe your existing data and return your phone to 'out of the box' or will install another country/network firmware."

2-What is Difference between the HOME-CSC and CSC?
3-What happened with both of them if i will flash with one of them ?
Guys ill wait for your reply ......hope so you will guide me in this matter
let's say you wanna update your phone without wiping the data u have on it. you use the home csc. If u have custom recovery and custom rom and you wanna go back to stock firmware you flash the csc file.

But what's the difference between CSC and HOME_CSC?

Didn't he already answer that question?
Home_CSC: Flash the firmware without wiping the data (if you just want to update the ROM)
CSC: Flash the firmware along with a complete wipe including data (mostly used in cases like bricked phones or Go-Back-To-Stock situations)
I always backup data and do a clean install with CSC ! Its recommended.
When I wanted to swap the firmware from (V) Verizon to (U) Unlocked, I had to use CSC simple, the Home_CSC gave an error. So I assumed the existing data cannot be "saved" when firmware are of different types.
I have asked about this and I wasn't that lucky to get an answer, so I just tried it (trial and error).
However, I think the data wipe is just a side-effect, not the purpose of CSC. Changing the CSC will always wipe data, including any custom software from the previous carrier:
https://productioncommunity.publicm...ung-Phone-Info/m-p/53208/highlight/true#M6228
In my case the original Home_CSC, had only VZW (Verizon) code available. The new unlocked firmware brought in 15 different CSC codes that can be applied when a SIM from one of those providers is introduced in the phone. Phone INFO shows those codes.
@NaJeEb303 He did answer, but he didn't make it clear. Only after knowing the answer I can understand what he meant. So thanks to you for clarifying.

Brother when you are flashing firmware with same csc as your previous firmware then you can use Home_csc and if you are flashing different csc firmware then you have to use file which starts with csc. You will lose data when not using home_csc because it contains different partition information and flashing this will delete you previous partition resulting loss of data but a successful flashing if you are stuck with home_csc. Hope you got your answer.
where do i find the HOME_CSC file?
Hey all,
i just used Odin3-v3.13.1 to upgrade from:
G935FXXU2EREM - GALAXY S7 EDGE SM-G935F DBT GERMANY
to:
G935FXXU2ERG2 - GALAXY S7 EDGE SM-G935F DBT GERMANY
First i selected all AP, BL, CP and HOME_CSC and started flasching. At the very last step (think it was the csc part) it failed.
The Phone said i thould have to use SmartSwitch to get Recovery. So i just opened odin again and just selected AP, BL and CP no csc this time.
That worked. Phone booted, did a bit upgrading and optimizing and now iam on 01.July upgraded. All fine!
But now iam really confused about csc in general.. what is it doing? And is it safe to just leave any csc file empty in odin when doing an upgrade?
No idea? Maybe i should better start a new fred for that
how can i get home_csc for samsung note 3 n900? thanks

I was answered this on Reddit
I started a thread on Reddit about how to get OTA after stock ROM flash, and the guy said that if I used the CSC file in the CSC field in Odin, I should still get OTA, so I guess it just means you would get OTAs on it. I think it depends on other factors such as build number and others too though, so I would research first.

Not 100% sure, but I have a unlocked S8 + and wanted VoLTE from my carrier, so i flashed the CSC file that belongs to the carrier that has VoLTE, and it worked fine It didn't wipe my data. but you have to make sure to flash the CSC file that doesnt have the pit file inside it (this will repartition your phone and delete the data).
for example the stock firmware for my carrier comes with 2 CSC files.
CSC_EVR_G955FEVR1AQD9_CL11146180_QB13177317_REV00_user_low_ship.tar -- This CSC file will repartition my phone
HOME_CSC_EVR_G955FEVR1AQD9_CL11146180_QB13177317_REV00_user_low_ship.tar -- this CSC doesnt include the pit file and will not wipe my data.
So in your case you will have to check the CSC files and flash the correct one. And if your phone gets stuck on the samsung logo screen try flashing the whole stock firmware with the CSC for VoLTE from your carrier.
(make sure to remove userdata.img from the AP.tar file in the stock image, as this will also wipe your data too from my experience use Z-zip to create/Edit a tar file that can be flashed via Odin)
remember this isnt 100%, but has worked for me in 3 different phones.

Hello, I purchase a SM-G935F from a pawnshop today that was flashed with a custom ROM however it does not boot. The phone goes into download mode just fine and want to flash stock firmware but cannot find the USA version. The box came the phone and appears to be a USA version, the UPC code on the box is 8806088275123 and I check the IMEI on a website service and it came back with this model number SM-G935FZKLTTT and says it was sold in the USA. Any help from members would be greatly appreciated, thank you in advance for your help.

Yes, it is in the download. When you download Samsung firmware from Sammobile or Updato website they come in a zipped file. You'll need to extract the zipped folder which will give you multiple files labelled AP, BL, CP, CSC and lastly HOME_CSC.
This is an example of what the files look like when the files are extracted from the downloaded firmware zip file:
http://prntscr.com/k07am0
The non_home csc file is used to tell the phone to wipe the user data on the phone when flashed, the home CSC is used if you don't want to wipe the user data on the phone when flashing firmware.

If you are flashing Oreo firmware which is 8.0 you need to use Odin 3.13 or newer as the older Odin software does not support flashing Oreo firmware.
The only buttons you need to click are BL, AP, CP, CSC then start and nothing else.
The default check boxes under options tab will be auto reboot and f reset time. Others should be left untouched and not checked.
You'll need to reboot download mode again which can be done by holding the download mode keys until you get that blue screen again or that it says that something ran into a problem with the blue screen which allows flashing as well.

Hello again, well I thought it worked because I got a PASS in Odin however, when the phone boots, I get a Black screen saying Samsung Galaxy S7 Edge then it goes to a blue screen with the android logo and it says erasing at the bottom for a few seconds then the screen goes black. The phone still goes into download mode however, it will not go into recover mode. Before flashing this I could get into recovery mode but would see a custom page with loading and rebooting options. Am I missing the stock boot loader? So sorry to keep bothering you about this.
