So did you managed to change the last CSC ?? if so, can you tell me how did you do it? and what carrier are you using? please
[Samsung Galaxy S8 Guides, News, & Discussion] ImpheOtus:
I'm on Telcel, but that doesn't really matter. All I did was following the guide flashing MXO firmware (to get rid of Telcel branding and apps), changing CSC to Mexico, and that's it.

You can't change the last three digits as they are hardwired onto your phone.

I'm from Mexico and have a S8 (FXXU3CRGH)

I think is imported from the US so I'm not able to use Samsung Pay

I downloaded MXO firmware with U3BL since I don't have a carrier but my S8 is in U3 BL and in your post you mentioned only U2 BL.

I'm confused. Shuld I download an U2BL or I can't can't change my CSC since I'm in U3BL already? Can someone help me
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
Look some posts back I posted a link for combinaton for U3BL. You can change your csc without problem following this guide.
[Samsung Galaxy S8 Guides, News, & Discussion] GuruMitar:
Sorry I've never done this. So I follow this guide using they MXO firmware that previously downloaded and the combination you posted?
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
Exactly. Just be sure to download the right combination for your phone. I provided only for exynos models (G950F and G955F)
[Samsung Galaxy S8 Guides, News, & Discussion] GuruMitar:
I don't get it. What's the combination for? I mean, when will I use it? Do I use it instead of AP, BL, CP or CSC in Odin? I think this is not for me :crying:
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
No, I mean just be sure what combination file you're downloading. If you want, you can PM me. I'm also from Mexico.
[Samsung Galaxy S8 Guides, News, & Discussion] GuruMitar:
Could you explain me this please:

"5.	Odin Flash the downloaded combination file on AP, and the newly created Home CSC tar file on CSC."

Thanks
[Samsung Galaxy S8 Guides, News, & Discussion] AliceVonderlust:
This method does not work on the S9 Plus G965F/DS even with the correct combination ROM. I used G965FXXU2ARG1 and G965FXXU2ARG2, none worked.
[Samsung Galaxy S8 Guides, News, & Discussion] GuruMitar:
In step 5 I switched my device in download mode, then I flash it with Odin by adding combination file and the new created Home SCS but when I do that Odin crashes and nothing happens.
[Samsung Galaxy S8 Guides, News, & Discussion] dfxtv:
Thank you for this guide

A favor, my phone G950F update to U3 bootloader, following your instructions, I try with the last MXO firmware (G950FXXU3CRHA) available in SamMobile with your combination as AL file that you kindly share us :) (G950FXXU3ARG1). Odin starts fine, but stops around 20%~25% of progress, after several minutes (more than 15) I need to cancel the process (no error) and load the plain firmware to recover the phone.

Any idea what is missing or what I'm doing wrong?

Thanks in advance
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
I think you want to say AP, you should load the combination under AP tab in order to flash it correctly.
[Samsung Galaxy S8 Guides, News, & Discussion] dfxtv:
Yes you right, I mean AP (not AL, AL option doesn't exists in Odin :silly:)
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
Haha. I guess your missing something. Did you flash MXO firmware first?
[Samsung Galaxy S8 Guides, News, & Discussion] dfxtv:
Thank you for your quick response

I was having the MXO firmware for a few days before I try, but I loaded with HOME_CSC instead of CSC.

I'm doing this again from scratch following step by step and no luck so far, still lock @ 25% of downloading (Step 5), stuck on system.img

Combination file can be damaged?
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
Can be. Try downloading it again. It should work. And check that you're downloading the right one for your phone.
[Samsung Galaxy S8 Guides, News, & Discussion] dfxtv:
Unfortunately no luck :(

I download again from the onedrive that you post and I try the same file from other site, but both still stuck @ 25%.

I see there is a new combination file version: COMBINATION_FA70_G950FXXU3ARH1 from easy-firmware.com but they charge you and not found on google as free
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
Try with another that has MXO like Peru. I did it with Peru firmware from Sammobile
[Samsung Galaxy S8 Guides, News, & Discussion] dfxtv:
Thank you very much for your help

You won't believe which was the issue: the cable, I was using an usb-c to usb-c cable and was working for regular firmware installs, but for the combination file failed, I switch to original cable and the download goes thru, now I was successfully able to change my CSC code :D

Thanks again :good:

Hola, actualmente tengo un sistema con binario 4 [U4], quiero cambiar de CSC a una de Mexico, mi duda es, ¿El CSC tiene que ser tambien [U4] o puedo poner el sistema "combination files" con cualquier version de CSC?
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
Hola, una vez en U4 ya no puedes bajar a U3 (que es actualmente el más nuevo para México) tendrás que esperar a que salga el U4 para México y el combination v4 también para hacer el cambio.

Is there a way to change CSC without having to delete everything?
[Samsung Galaxy S8 Guides, News, & Discussion] orlandson:
No.
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
As far as I know, no.
[Samsung Galaxy S8 Guides, News, & Discussion] Overhead11:
Allright, so what combination file exactly do I need as my phone has bootloader v3.

Anyone ?
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
A few pages back I posted a link for the combinations for s8 and s8+. You can use them.
[Samsung Galaxy S8 Guides, News, & Discussion] Overhead11:
Thank you, but at the end i managed to just flash the new firmware and change CSC with odin and thats it, nothing extra more i needed to do :)

Hi,

One step is not clear to me:

.

How can I boot into factory mode?

I deleted the "hidden.img" line from the HOME_CSC_...\meta-data\download-list.txt file. Is this correct? there is no file named "hidden.img"

And for bootloader V4, I assume this is a correct firmware file.

Thanks
[Samsung Galaxy S8 Guides, News, & Discussion] hckrnewb:
Factory Mode

Hello i have a G950F ive been fortunate to not brick my phone but im having trouble i follow the instructions and i cant seem to get my phone into factory mode.

Is there a possibility you can make a video or something. Or can someone give a more detailed step by step process.

By the way im not new modding my android devices GS2 GS3 PacMan rom cyanogen rom Aokp and a few other Htc Evo shift with miui rom GS5 with miui rom slim rom.

I really want my spay and google pay.

Any help would be grestly appreciated
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
Do you have the appropriate combination file? For what I see you're on BL v2 You need a combination v2 also.
[Samsung Galaxy S8 Guides, News, & Discussion] hckrnewb:
I downloaded Firmware from sammobile Uk(BTU) or something like that im away from my computer atm.

Its the june 2018 update that upgrades the bootloader to v2.

I followed the instructions modified the filesbrepacked them as a tar file.

However i dont know what factory mode is. Is that the recovery mode or odin mode(download mode)
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
It's another kind of firmware. It's called combination file. So, you need the firmware from Sammobile and the combination. The combination file is the one that lets you enter to factory mode. You need it in order to follow this guide. The version of the combination must match with the verison of the firmware from Sammobile.
[Samsung Galaxy S8 Guides, News, & Discussion] hckrnewb:
The file in the picture is the one i downloaded

Where can i find the combination file?

I did a google search and i didnt find anything??
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
I have combination file but for BL v3. Usually you have to pay to get them. You can download from Sammobile firmware with v3 and use the combination that I have. But if it's a must to stay on v2, then you should look for that comnbination in forums or pay for it.
[Samsung Galaxy S8 Guides, News, & Discussion] hckrnewb:
Ok is the process still the same for bootloader version 3?

And what changes come with bootloader version 3?
[Samsung Galaxy S8 Guides, News, & Discussion] Battery03:
I actually found a link for the combination v2. If you want it, PM me and I send it to you. And yes, the process is the same for ay version.
[Samsung Galaxy S8 Guides, News, & Discussion] hckrnewb:
Pm sent

[Samsung Galaxy S8 Guides, News, & Discussion] bovoro:
I do not know if it happened to you, but when using the Combination v4 version, the CSC FILE must be corresponding to the version of the month the letter I at ARI , COMBINATION_FA70_G955FXXU4ARI1_CL12792727_QB19841692_REV00_user_mid_noship look at the part ARI1, I need an ARII version or if not, I do not see the CSC list to choose, in my case i use TTT ROM HOME_CSC_OXM_G955FOXM4CRI5_CL14315050_QB19732162_REV00_user_low_ship.tar , and works, if I use CRJ5 doesnt work.

Hello [MENTION=3786196]bovoro[/MENTION],

I am just about to flash a CRJ5 CSC but the only combination file I found is the one you have used, should I try anyway or do you recommend using the CRI5 ? and what do you mean by "I don't see the csc code " ?

Thank you
[Samsung Galaxy S8 Guides, News, & Discussion] bovoro:
I recommend you flash the version according to the combination rom in this case the CRI5, since it is contemporary to the rom combination and then you can install the CRJ5 update, another thing to take into account, you must choose a MULTI CSC rom , in which come the desired CSC, some are not.

What I mean when I say that I do not see the cSC code, is in the list being in the firmware combination
[Samsung Galaxy S8 Guides, News, & Discussion] AyoubK:
[MENTION=3786196]bovoro[/MENTION],, Thank you very much, now it is more clear. I will redownload the CRI5 firmware and use it.

How can I change CSC to Thailand

I have S8 G950F

CSC = ROM/ROM/ROM

Android Pie non-rooted

CPU: Samsung Exynos 9 Octa (8895)

Knox 3.2.1

Thank you!
[Samsung Galaxy S8 Guides, News, & Discussion] rilley:
1. Should I download the original G950FXXS4DSC2 firmware and flash it and then change the CSC? This should be the steps? Can anyone please point me to the directions to change the region to Thailand (THL) or at least India (INS) ?

I`ve been searching for G950FXXU4DSBA on

https://updato.com/firmware-archive-select-model?q=SM-G950F

and

https://www.sammobile.com/firmwares/galaxy-s8/sm-g950f

And I can not find the G950FXXU4DSBA on India, Thailand, Vietnam neither the G950FXXS4DSC2

2. What I saw there is an older version for India (INS) on https://www.sammobile.com/firmwares/galaxy-s8/sm-g950f/INS/ but with different CSC/PDA than mine ( I have PDA G950FXXS4DSC2 and on the site the PDA is G950FXXS4CRLB ), should I use this version?

3. and if I flash it the older version, I will get the OTA update back to Android Pie?

4. Or are there any chance to brick my phone?

Attached some photos with what I have.

5. Also, after changing the CSC to THL (Thailand), I will be able to use the carrier in my country (RO) as it is now (I mean to make phone calls)?

Engineer bootloader is used for using specific softwares without tripping knox iirc, it is not compatible mostly with devices and is very rare to find and make it work..

But here is the combination rom you wanted, use it for recovery or csc changing purposes as mentioned in the thread. Both files you wanted are the same. This is the bootloader version 4 combination rom for S8+, if you wish to root through using it (thinking it won't trip knox), sorry to say but this trick doesn't simply works according to my knowledge..

[Samsung Galaxy S8 Guides, News, & Discussion] ocujos:
Hello,

Just wondering if anyone has performed a factory reset *after* changing CSC code? Has CSC code gone back to phone's default or it's remained intact?

I'm about to have a battery replacement done at Samsung and they've told me they would perform a factory reset. I'm concerned that CSC would go back to the original (XSA in my case) which obviously I do not want. I'm on INS CSC atm which I want to keep as it allows call recording AND Samsung Pay to work.

Also, I'm on Android 9 pie at the moment and bootloader is on U5. Does Combination firmware exist with U5 Bootloader? Apparently, it's not possible to downgrade Bootloader thus making U4 based Combination firmware useless.
[Samsung Galaxy S8 Guides, News, & Discussion] ocujos:
Just wanted to let people know how I've changed CSC on my S8+ SM-G950F. I was unable to use instructions from OP so I had to find another way. There a number of videos on YouTube showing how it's done (FRP removal).

Using the latest Odin I flashed Combination firmware matching my U4 bootloader (AP - section in Odin). Also, I flashed a CSC from a multi-CSC stock firmware. When phone booted into Combination (aka Engineering) Firmware, I selected IME icon and typed *#243203855# on numerical pad. This brings up a menu where you select CSC that you want to install (I selected INS for India). Wait for phone to reboot. I then flashed *stock standard* S8+ multi-CSC firmware as usual, in Odin. Phone works fine with Australian SIM while retaining INS CSC features, like call recording.

Software Information now shows that Service Provider SW ver. is....INS/INS/XSA (XSA is my original CSC , i.e. Samsung stock , unbranded, Australian firmware).

Feel free to ask questions.

My only concern is that factory reset may change CSC back to original one (XSA) thus causing me to lose features like native Samsung call recording. I haven't been able to find a Combination firmware with U5 (V5) bootloader. Please post a link if it exists.
[Samsung Galaxy S8 Guides, News, & Discussion] ocujos:
To answer my own question about doing a full wipe on S8+ with a changed CSC:

Doing a Factory reset will reset CSC back to phone's factory CSC. In my case, it went from INS (India) to XSA (Australia). Considering that I'm now on U5 (V5) bootloader and Combination firmware not being available, I can't change CSC.

Has anyone got any idea how to change CSC? My last resort is to root the phone which I might reluctantly do as I wouldn't be able to use Samsung Pay. :(
