[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 (

Help me understand CSC codes, Flashing different firmwares and Odin

OK - I started with a unbranded UK A300FU - CSC code BTU on 5.x
I flashed a (supposedly) UK VOdafone 6.0.1 rom using Odin and the ROM n the AP sjlot
It appears this failed - my Modem wasn't updated an WiFi failed - the advice elsewhere is to go into download from a cold phone.
Also, it would appear the firmware wasn't UK, but some germanic version
I restored from a TWRP backup
My phone details now says the "orginal CSC Code" is VD2
If I want get back to showing Original code as BT should I re-flash in Odin the firmware that matched the twrp backup ? If so , should I stil use the AP slot, or should I use the CSC slot?
Many thanks

Use CSC slot.
Also, the reason why your TWRP backup restoration didn't touch the CSC is that it has it's own partition, which one normally does not backup.
You could flash an entirely unbranded marshmallow rom of your choice, and flash the BTU CSC of lollipop, it should still theoretically work.

Upgrading to Nougat using firmware from different region

Hello,
I am planning on installing the latest official UK BTU firmware on my Samsung Galaxy S7 Edge (SM-G935F), my CSC is CRC (Chile). Before proceeding I would like some help please. I know this may have been asked plenty of times before, but each case is different and in addition, I have some specfic questions about the process that I haven't been able to answer from other posts.
First of all, here is my phone info:
Product Code : SM - G93 5FZKLCRC
Original CSC Code :
Firmware 's CSC Code : CRC
Active CSC Code : CRC
Available CSC Codes : CDR , CHL , CPA , CRC , CTI , CTP , CTU , PCT , PET , PGU CSC
Country : COSTA RICA / CR Mobile Operator
Claro / 71203
I already have the official firmware and Odin, and the process seems pretty straightforward, extract the firmware, load it into Odin, put phone in download mode, flash. Oh! and hard reset seems to be the result of doing this which is ok. However, I am unsure about the following:
- The current firmware on my device seems to be Multi-CSC and I want to install a single CSC, what considerations should be taken when doing this? Is there any undesired effect?
- When extracted, the firmware package has 5 files: AP, BL, CP, CSC and HOME_CSC. I know I can ignore HOME_CSC, but, do I load all other 4 files in their respective field in Odin?
Should I ignore one or more of these files?
- Do I need a pit file and repartition or am I ok flashing without repartitioning?
- Can I easily go back and flash my original CRC Mashmallow firmware? Is the process the same but backwards?
Any help will be greatly appreciated. Thanks in advance.

Home CSC for SM-A510F?!

Hi Guys,
I've got a Galaxy A5 2016 (SM-A510F DBT) from a friend. The device seems stuck at the last system update and does not start anymore. Since he did not backup his data, I try to flash the latest firmware via Odin. I read that there is now a 4-part firmware version for Galaxy devices and two CSC files. The Home CSC file supposedly does not reset the data when they flash, but I can only find the regular CSC files. The firmware was loaded with SamFirm.
Someone an idea?
Thanks!

SM-G935F Firmware for United States

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.

Thank you my friend, trying now.

I forgot to tell you that factory reset is required when switching from custom rom to stock rom so make sure you flash the non home CSC file and not the home_csc file.

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.

Hello again Benjamen50, it failed on the first try, do I need to check re-partition? or Nand Erase? What about a Pit file? sorry to keep bothering you but I appreciate your help.

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.
