Question CSC Change with SamFw - Samsung Galaxy Z Fold 4

Hi, guys, I'm a bit new to this, but I would like to change the CSC from THL (Thailand) to ZTO (Brazil) on my Z Fold 4 using SamFw, as it seems simple enough as just clicking a few buttons, but I have a few questions:
1. ZTO is not on the list of CSCs it reads from the device, is it safe to proceed?
2. Will it trip knox? Will i still be able to use google wallet/pay? WIll i receive OTA updates?
3. Am i missing something or is it as simple as that for Samfw? Should I do anything else?
Thank you very much!

Hi Rodrigo, I believe I can answer a couple of your questions with the experience of changing CSC on my Fold 3 with Android 13 and one UI 5.0 from EUX to INU.
2. Will it trip knox? Will i still be able to use google wallet/pay? WIll i receive OTA updates?
No, it wont trip knox. Yes, you can still use Gpay. I am yet to check/receive OTAs. will update once I receive one.
3. Am i missing something or is it as simple as that for Samfw? Should I do anything else?
Its pretty simple and straight forward. Doesn't require any factory reset or wiping cache partition. Just connect the phone to a computer with your phone drivers installed, enable usb debugging in developer options and open the test mode with *#0*# and get to ADB tab -> select CSC Change -> select the desired CSC from the list of displayed CSCs which your phone model supports. Phone just restarts after this and u have ur phone with the new CSC n related content.
Please check my thread with detailed info on this here:

Problem updating T700 to 5.0.2

Ok.... Crazy Situation here.
I can not update from 4.2.2. When I try to update I get 'Registration Failed' message right before the update should start. I did register this tablet with my account @ samsung, but no joy.
Here is the backstory on this: My S 8.4 battery connector broke and I got a used main-board off ebay. I replaced it, did a factory reset, and I got 4.2.2 working. However no lollipop. I checked the codes on this 'new' tab:
Country is: France/FR
Original CSC Code: AUT
Firmware CSC Code: MKT
Active CSC Code: MKT
Current Firmware as reported by Kies: T700XXU0ANE3/T700MKT0ANE3/T700XXU0ANE3/T700XXU0ANE3 (MKT)
Yes, all one line.
I'm in USA and I'm hoping to get to the correct firmware.
I want to use odin to update to 5.0.2, but just want to make sure I can use this rom:
Product code XAR
PDA T700XXU1BOK1
CSC T700XAR1BOK1
Is this my ticket out of this problem?
Thanks

You should be just fine flashing T700XXU1BOK1 with Odin. I've installed other region firmwares before without issue.
EDIT: If you'd prefer the French region though, go here (http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647) and use the software provided to download whichever firmware you need or want. Just enter the PDA and CSC into the appropriate fields.
Thanks noxarcana.
I was hoping that this would do it. BTW: Nice little tool you linked to!
From what I read the CSC codes now come from inside the ROM, so once I go with T700XXU1BOK1, I will get USA region? Just want to make sure.
And this update WILL wipe everything out, right?
Did anybody try IronMan ROM for T700? http://forum.xda-developers.com/galaxy-tab-s/development/stock-tw-rom-galaxy-tab-s-8-4-t2995235
How does this MOD deal with the country codes? Would it be USA?
Thanks
So, I thought I had replied to this but apparently I my mind lied to me. Yes, if you flash BOK1, you will be using the US region (also known as Cellular South...for some reason).
IronRom is one of my top 3 roms for this device! Since it is a custom rom though, you don't have to worry about CSC and PDA codes. Just make sure you get the correct zip file for your device (ie: T700, 5T800, etc.).

S Health & Secure Folder break after official ODIN update ?

Hi,
Wonder to know if someone encounter same issue as me.
When i received my Note7 from Orange (France), I immediately change operator ROM to official Samsung ROM which i grabbed from Sammobile.
After restart and first launch, i download my apps from Google Play and use S Health fine.
But now i can't use S Health and Secure folder ?
When i try to launch S Health, a message appear and said me: " Cannot Open......blabla...., my phone is threatened , you c'ant use this app, cause KNOX wasn't available on threatened phone..."
I did not root my phone, did not install wild APK only APK from Google play.
I can't figure out.
Any suggestions ?
Thanks !
I will try those steps:
1. Install phone info samsung from play store
2. Open and check your csc code ( original vs active vs firnware csc code
3. If you have different csc as I suspect then install with odin a new original software with a separate csc file. Maybe those apps check the status of csc active code.
P.S. did you factory reset your phone after writing new firmware with odin? Or you just booted your new firmware ?

The above poster is correct, i faced the same issue as i flashed the AP section only (previously this contained the lot) however secure folder failed.
I flashed the latest UAE firmware and placed in the BL / AP / CSC and the other one and all back to normal.
On the UK version my first install showed current CSC but no original or firmware csc, flashing the lot as detailed all but the original appeared and secure folder worked

Problem after changing CSC

Hello,
I have changed the CSC of my Active 2 44mm (not LTE). Everything has been correct, except for two things:
1 - I still get the green letters when I start the clock, on the Samsung Galaxy Watch Active 2 presentation
2 - Now I try to upgrade by OTA (through the phone's app) and when it reboots, it says that the firmware could not be installed.
How do I fix both? Thanks
Put everything back the way it was (Fully Restore to Default) and try to update software.
Are you able to identify Model Name?
I hate this mm nons.nse.
Example:
SM-R820?
I am too lazy to google how long is yours... Firmware.
Colors in Booting is Engineer Bootloader sboot.bin (from Combination firmware) is still on device... this brings FOTA over the air to fail...
Because wrong Bootloader on device... from "chain of trust" selfcheck...
Best Regards
hi, I have a similar issue with the sm-r825f, after I changed csc to Germany... I got a watch from UK (BTU) unfortunately and wasn't able to set up esim. Now after I changed csc and flashed R825FXXU1ASJ3, esim works fine but I am stuck on ONE UI 1.5 and scanning for updates keeps failing.
What's the easiest way to make OTA work again?
Can I simply reflash a certain firmware? Can you recommend or link the files?
Sry if any information is missing!
Thank you all for your help!

How to change the service provider software version? S20 (SM-G980F)

Hello guys!
I have a sim unlocked Galaxy S20 (SM-G980F) from Orange Romania and I want the new update (Android 12 and OneUI 4) and to get rid of the pre-installed apps from Orange. Apparently it is a known fact that some mobile network operators tend to postpone the new firmware updates (which I think it's stupid) because they have to 'test' it and load it with a bunch of useless apps that nobody needs. It wouldn't have been such a problem if this would happen in a timeframe of a few days, but usually it takes months. I contacted Orange and they said the upcoming update is being 'tested' and it will probably be released sometime in March (which again, it's just stupid).
I am looking for a way to change the Software Service Provider from ORO to ROM (or something else, to get the update directly from Samsung and not Orange); Samsung and Vodafone already rolled the update.
So, I have a few questions:
1. Can I change the Service Provider? (SM-G980F on Android 11)
1.1. If yes, how can I do it? Can you guys kindly guide me towards a tutorial?
1.2. Can I do it for free?
2. Should I just install a custom ROM? (I have seen many on this forum, but most of them seem to have problems if the high refresh rate is enabled etc... any reccomendations?)
Thank you guys! Any advice is much appreciated!
PS: I am kind of unfamiliar with these things, i used to flash custom ROMs on my old phones back when Cyanogenmod was a thing and I've used Android since 1.5. I don't know what changed and what's new so any help is welcome! Thank you!
First off, why do you even want Android 12 so badly? Early adopters catch all the bugs. And moreover, if you want to mod your phone, you'll quickly notice that a lot of popular mods aren't yet available for Android 12. As of today:
There still is not an official Magisk release for Android 12 (only Canary/pre-release builds).
Xposed module GravityBox for Android 12 has not been released.
Xposed module Firefds Kit for Android 12 has not been released.
And if you start modding, you're likely to find more things that just don't exist for A12 yet.

It used to be fairly easy. You could open the Preconfig dialog with a dialer code and change your CSC code. Loss of this functionality in recent software is lamented loss of this functionality in recent software is lamented here. There are many discussions about changing CSC code that make mention of the commercial software and service Samkey such as this and this; I have no personal experience with their offering so I can't recommend them. Interestingly it seems from the discussions that there is typically some lag between an Android release and support for that release from Samkey, so the trend I just referenced above is hardly an isolated phenomenon.
It's worth mentioning that the changing of CSC codes has been discussed extensively throughout the forum. One of the downsides of XDA though is that discussion is heavily segregated by device, so you can easily miss what you're looking for if you search only in a sub-forum for your device.
1.2. Can I do it for free?

With root, certainly. Otherwise, it is not so clear based on the above.
You can launch the Preconfig dialog from a root shell:
am start -n com.samsung.android.cidmanager/.preconfig.PreconfigActivity
I've noticed that in some configurations (notably when CSC code is VZW), the Preconfig dialog seems to be somehow disabled. However, with root access you can also simply edit /efs/imei/omcnw_code.dat.
2. Should I just install a custom ROM? (I have seen many on this forum, but most of them seem to have problems if the high refresh rate is enabled etc... any reccomendations?)

That's your choice. Browse the ROM section and see if there is anything available for your device that you like. Custom ROMs vary greatly in user experience as a consequence both the ROM's objectives and the developer's skill.
They all have a few things in common though: they will irrevocably trip the warranty void bit and cause a loss of Knox-related functionality (notably including Samsung Pay). They also will prevent you from receiving official OTA updates.
Another option is that you can simply root your device and start modding away yourself. Basically, that workflow is something like this:
OEM Unlock.
Boot into download mode with vol up + vol down + insert USB cable connected to PC.
Volume up to confirm unlock.
Flash TWRP from ODIN.
Flash Multi-disabler from TWRP.
Wipe /data from TWRP.
Install Magisk from TWRP.
Once you have root, you can not only change your CSC code as desired, but edit the read-only filesystems on your device, notably including the filesystems containing the CSC. It's even possible to blow away the CSC content completely and integrate the CSC content from the ROM of another region.
Of course, it goes without saying that you need to back up anything important on your phone before you start any experiments. Of particular importance, be sure to back up efs and sec_efs with TWRP and make sure the backups are stored somewhere safe (e.g., on a PC) before you start attempting any changes to efs partitions. A damaged efs partition is one of the easiest ways to render your phone useless. Note also that custom ROM installation almost always involves wiping /data somewhere along the way.
So, the bloatware you talk about is located in /product , /hidden or /odm depending on how your phone is configured. I can help you out contact me on telegram @cha0scl0wn. Regards.
Thank you guys so much for your replies!
I managed to launch the Preconfig dialog (dialing *#272*62826# in the stock phone app - other codes did not work, also tried the google phone app - nothing) but the only options to change the CSC are those in the picture (AMO - Orange Spain, FTM - Orange France etc). Basically I can select another Orange CSC which does not help. I want to change it to unbranded, to get the firmware updates directly from Samsung.
Now, if I root the phone, will I be able to change ORO to unbranded? But I'm a bit confused because rooting cancels OTAs, right? So I need to root, change CSC to unbranded (if possible) and then install the update myself? But then I will have to manually install every update?
If I root, change CSC to unbranded, install the update, unroot will I get the OTAs?
Rooting also kills Knox and Samsung Pay?
Thanks again guys for responding! I appreciate it! Cheers!

Wow--you got lucky: I wasn't expecting the dialer code to work based both on my own experience and reports here on the forum. The Preconfig dialog is really just a testing tool: it allows you to select other CSC codes that already exist within the firmware and see the effects of those setting changes. I don't know if there is an effective unbranded configuration included on the OXM package (i.e., similar to XAA in the OYN package).
I don't have a lot of experience with the OTA updates (all my devices are unlocked).
Now, if I root the phone, will I be able to change ORO to unbranded? But I'm a bit confused because rooting cancels OTAs, right? So I need to root, change CSC to unbranded (if possible) and then install the update myself? But then I will have to manually install every update?

You'll still be able to select any CSC. I suppose in theory you could create your own CSC configuration for an imaginary carrier, but the route that I took was different. I stripped out all the unwanted junk out of the optics and prism images (along with de-bloating I did in a lot of other places in the ROM). I also edited all the XML configuration files that ship with the CSC to my liking (think: call recording on, shutter sound menu on, etc). After installing the resulting ROM, there was pretty much no carrier-specific software running on the device; splash screens, sounds, and other markings were also gone. I actually ended up adding a handful of carrier-specific content back to my ROM to get Wi-Fi calling working since it appears that the carrier I use (VZW) has a slightly nonstandard implementation of the feature.
But yes, once you head down this path, you'll be updating your phone by yourself, and it likely won't be the most enjoyable activity. I also don't feel the need for every single update, and I especially have no interest of moving to A12 in the foreseeable future.
Keep in mind that you should be able to pm disable bloatware packages that are really bothering you even without rooting/unlocking your bootloader.

Question How to update to Android 13 today?

Hi, I have some spare time now and need to reinstall my Fold3 anyway.
So I would like to test Android 13 and am looking for the safest way, of course without triggering knox.
Can I download and flash via Odin Indian firmware from here: https://samfw.com/firmware/SM-F926B/bit/all/av/T(Android 13) ?
Or should I register as a beta tester?
My csc code is OXM via *#1234# and EUX via "samsung phone info" app.
Which way to go, please? Or point me please in the right direction.
Thank you.
Good question, im also interested in going odin way, so i could also need a secured way
I downloaded the INU rom and to keep data flash HOME_CSC, it keeps the csc that you have now
So did I. I flashed INU on my EUY F926B. When you flash Home-CSC you will keep your data.
Is that absolutely secure that ill keep my apps and setting? Got 2 Authenticator Apps for work on it

Been there, done that, if you have critical work apps, then wait for the official update if you are not 100% sure what you are doing.
ODIN says succeeded, so im crossing fingers. Have worked with it on an older Galaxy before, but never with Firmware from another country. In CSC ive taken the HOME_CSC_OXM_F926BOXM2DVK3_MQB58858275_REV00_user_low_ship_MULTI_CERT.tar.md5.
That should be right

I can report success, Authenticators are working, CSC is like before
Problem solved, I received official update today
Anyone in the US using VZW get the update?
