[Q] Changing Galaxy S4 CSC (i9505)

Hi everyone,
this maybe a very noob question but how do you change the CSC on the S4?
I recently flashed an unbranded UK firmware onto my Australian S4, back with my old phone, I was able to change the CSC with *#272*IMEI# though that doesn't seem to work now. So any ideas? Any help would be greatly appreciated. I want to change the CSC to a UK CSC so I'll be able to receive updates OTA or through kies.

1.Download the appropriate firmware for your region from sammobile.
2.Extract Hidden.img and cache.img
3.Now compress these two files together into a .Tar file.
4.Flash this in PDA section of Odin
5.You now have correct CSC

Is anyone having trouble changing their CSC?
I've flashed the pre-rooted UK Firmware, and used CSC Changer to set the CSC to BTU.
It automatically re-boots, but the CSC hasn't changed.
I boot into recovery and perform a F.Reset, and the CSC still doesn't change to BTU.
As far as I can tell, I'm following all instructions correctly from here.
http://forum.xda-developers.com/showthread.php?t=2250824
"If someone want to change CSC, please use this app: Samsung Galaxy S2/S3 CSC
After using this app you MUST reboot into RECOVERY for the changes to take place.
Don't worry if you see some errors in recovery, it's NORMAL as "hidden.img" is excluded..
WORKS perfectly! TESTED!! "
I don't know what I'm doing wrong, and I'm getting increasingly frustrated!

Tried that without success. Got a failure in Odin.
There's no hidden.img nor cache.img but hidden.img.ext4 and cache.img.ext4. Are these the correct files?

I downloaded latest btu UK firmware
Loaded with odin
Did a factory reset
Switched if and then went into recovery mode
Rebooted and btu was activated
I was not rooted

they are just ext4 formats so u could mount it on linux or something else..
use mkuserimg.sh command to convert

I'm also interested in this. I also changed from Australian firmware to UK. Since changing I've noticed HD voice (wb amr) is off (check by typing *#0011# into dialer then menu key>back>menu key>key input >enter '1' then wait till menu appears >WB AMR Status.)
Prior to changing roms both WB AMR Setting and UTMS WB was On. Now they're both off. I did some searching and apparently its tied to the CSC.

so.....how do we change csc to s4? i have installed unbranded rom, wiped but csc remained the same. how de we change this?

I9505 stuck with wrong CSC

I am also stuck after trying several suggestions of fixes..
The Sammobile firmware for NEE (Nordic) gives a CSC of BTU, i previously had H3G
Looks like we will have to wait till DEV's get time to build a work-around.
Doing web searches there are several dodgy sites that claim older changers work on the S4 & also giving instructions to install via the old way with the 3 files, instead of just the PDA.

i just reboted in stock android recovery (hold vol up + home button+ power),and it said "applied multi csc....and it changed the csc to the my curent firmware¨s csc

I am trying to set my csc to BTU. Im using csc changer app.
However everytime I run it, I dont get a screen allowing me to choose the csc as they show in guides.
I know the app works, since its changed my csc from EVR to DBT (since my rom is german based).
What am I doing wrong?

After playing around with several stock firmwares and Odin, I accidentally stumbled upon a method to change the CSC of my S4 I9505 without the need to root the device. I successfully changed from the original TGY (Hong Kong) to SIN (Singapore) and then to DBT (Germany). This is what I did (in summary)
Make sure you take a backup via Kies if you need personal files
Download the respective stock ROMS from sammobile.com or samsung-updates.com or see thread on Stock Roms on XDA
Extract zip to get tar.md5
Put device into download mode (Vol down+ Home + Power) and Flash using Odin (PDA option)
Wait till device reboots back into Android after completing the flash and recovery
Once device reboots, do a Factory Reset via Settings > Accounts
Once device reboots after Factory Reset/recovery, enter the google account info and restore settings and then turn off the device
Boot device back into download mode (Vol down+ Home + Power)
Re-flash the same downloaded firmware for a second time via Odin
Once the device reboots after the 2nd flash, your CSC should have changed to the CSC of the ROM you downloaded, and Kies also should show that CSC has changed and it should allow future updates via Kies or OTA

It's unnecessary to do steps 7-10. You may check your new CSC in recovery mode after restoring the device.

I was thinking so too but that's exactly what helped me to change CSC on my i9295 (very common with i9505). After the first wipe I still had the old CSC (I checked in Kies though). After the full procedure I have proper CSC in Kies. Probably there is a easier way but this one works also.

You had to restart Kies, it would show the new CSC then.

Of course I restarted Kies. I think what I have not done is entering Recovery once the Odin flash is done. Entering Recovery gives the following: Applying Multi-CSC... Applied the CSC-code: XXX (my new CSC here). And I think here's where all the magic happens.

At least for me, my device goes in to "Recover Booting" after each Odin flash as well as a factory reset. I actually tried a a manual recovery boot via Vol Up + Home + Power after the factory reset in step 6, but it did not change my CSC, hence doing all steps is what worked for me all the time. I once skipped the Google login part after the factory reset and it didn't work that time either and had to do another factory reset, google login and another re-flash.
I wish there is an easier way, the reason I have been experimenting with different firmwares is to see if I can get LTE working natively, since phone does not show the LTE option under Mobile Networks. We have 2 operators offering LTE here in Sri Lanka but Samsung only sells the I9500 officially here which does not have LTE, so got down my I9505 from HK. So far I have had to use Viaero 4G Toggle app from the play store to enable LTE, while it works, enabling LTE this way is a huge battery drainer!

but is there a way to extract CSC from a particular firmware and flash only this?
I used to do it on my S3 by using the hidden.img and the cache.img but if I try in Odin on the S4 it fails (

Firmware - HOME_CSC - Odin 3.10.7

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?

CSC-HOME and CSC simple????

Hi Guys
i have a question i want to flash my galaxy s7 edge with Odin i want to ask that there is some confusion between HOME-CSC and CSC simple
1-Can you please guide me which one i need to select to flash my phone?
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.

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.

Thanks for replying mate. I wasn't able to enter "Recovery Mode" but I could get into the "Download Mode" and I flashed the Firmware again.
Turned out the problem was that I only flashed the AP file and not the BL, CP, and CSC files. Earlier we only needed to flash one file (that's why I got confused) but in newer models since S6 we have to flash all these files as well.

CSC cointains the pit file so it will auto repartition, and wipe your data.. (and internal memory) so if you just need to reflash the system but remain the data, don't include csc and will work, but only if the firmware is the same as the one you already have.. (for example for unroot) and remain your data... remember if CSC is attached to odin.. your phone will be fully wiped

I was changing Firmware on my device to another country's, so had to flash the CSC.

Failed official firmware install (SM-T580)

My device got FRP locked and so I used Odin to flash the official firmware from Sammobile and now I have T mobile menus like personal hotspot in my settings apps even though my device is the Wi-Fi only tab A 2016.
Here's how I got here:
I flashed the correct firmware, and in Odin I flashed the ap file, that's all. It succeeded but when installing updates, it said no command and went to the stock recovery. I factory wiped and rebooted.
How do I get rid of the T mobile menu's?
Any help would be appreciated
