hi
i used to have VoLTE on my unlocked samsung galaxy S9 (SM-G960FD)
i was on stock rom (G960FXXU1ARB3) when i had both VoLTE & VoWiFi , i had to reset my phone for some reason..... i said why not update and restart ? so i updated to G960FXXU2BRGA and i lost both VoLTE & VoWiFi
i tried downgrading to ARB3 but had no luck since the bootloader was updated.... so its not an option.
can anyone help me to get VoLTE back ? i really need it :crying: and i dont want to lose the warranty

Hi, you may download an app ''QuickShortcutMaker" on Playstore. After that open the app and search for "lte call". You may find Enhanced LTE Services under Mobile Networks. Select it and select try, now you may turn VOLTE on. Sorry for my broken english.

May I know your Original Country code(CSC). And, what is your currently active OMC(CSC)? You might use Phoneinfo app for checking the currently active CSC.

Firmware contains multiple CSC. And, if you flash the firmware via odin sometimes the phone boots with Random CSC. Hence, I strongly feel the device applied a default CSC other than Iran(THR).
Once more please confirm it using Phone Info app, you can find it on Play Store. Or else, check whether the good-old secret code *#272*imeino.1# works or not.
If nothing helps, go for a clean flash of the latest Iranian firmware by putting CSC(not Home-CSC) firmware file in CSC tab on Odin.

I just bought samsung s9 SM-G960U but can't it won't update to android 9.0 manually ! it says processing failed
I did some researches I found that it's carrier-related . Some solutions suggests that I use odin to update but I can't choose the right firmware !
In fact :
- when I try to check the csc using *#1234# it show g960usqu2are6 ( I think it's Verizon using google)
- when I log on into samsung website and enter my imei . The product info shows that my carrier type is Sprint
- when I check "about phone/service Provider SW " on my phone the first line contains TMB after G960U and the third line is TGY/TGY/TGY
I'm confused but I want to update my s9 to android 9.0 . Help me

get the firmware here
https://www.sammobile.com/firmwares/galaxy-s9/SM-G960U/VZW/download/G960USQU4CSC7/265795/
get the most recent version of Odin (i didnt source you a link for that)
open Odin on your computer
unzip the package and get your phone into download mode, connecting it to your computer. Allow drivers to install and when Odin recognizes your device by showing a random number in the port field. Then place the files in their corresponding spots in Odin paying attention to which CSC file you use as one factory resets the phone and the other simply applies the update. It is recommended to use the factory reset CSC when changing from different iterations of the Android OS. Press the start button, allow it to full run the firmware push. It will then automagically reboot (yes, automagically), and youre done.

Once a phone is unlocked, it stays that way forever. Firmware has nothing to do with a phone's locked or unlock status.

Depends how it was unlocked, seen a few members flash new firmware and the phone is SIM locked again, these unlock companies must use some modification to the firmware rather than unlocking it properly

Good to know. Wasn't aware that a phone could be unlocked with firmware alone. I guess it's a temporary overlay or something that "fakes" being unlocked?

Yea must be something that emulates the unlock somehow but once reset or flashed it's gone, always seems to be people who have bought the phone second hand unlocked, it has worked fine with their sim until they reset or flash different firmware, then it's locked again
No network on device after firmware update

i havent tried this method, but i did stumble across this
Boot your Samsung Galaxy S9 or Galaxy S9 Plus
Activate then access the USB debugging mode
Sync your Samsung Galaxy S9 or Galaxy S9 Plus to your desktop PC
Download this: EFS Restorer Express
Access the application and then open the EFS-BACK.BAT file
Choose a method in order to recover the EFS via Odin

Hey Guys,
Just wanted to check whether any working methods are around to change the CSC of a Note 10+
Couldn't find any guides apart from the ones which are in Note 9 Sections.
Any support on this is much appreciated!

Im also looking for a solution for this. SamKey's paid service is apparently supporting this but im unsure of the method their software uses and its a paid service. Users in Australia (like me) are having issues with RCS services through Telstra (TEL) because the Open Variant bought direct from Samsung not having the correct CSC. Some users have reported changing the CSC through SamKey successfully.
I have tried flashing with Telstra firmware but no luck.

I initially did *#272*IMEI# and was able to switch between CSC. When I switched to XAA, I was stuck and could not able to use the *#272*IMEI# anymore.. So I had XAA/XAA/ATT.. I saw many were stuck.
Found a solution that worked for me is as follows. Try at your own risk.
Downloaded the tool from
https://www.mysterious-dev.com/2020/05/changecsc-all-samsung-free-tool-android.html
and downloaded the ChangeCSC Software tool.. . watched the video couple of times.. The process lets you install custom THEME.. I was getting "Update" "Delete" and "Buy" ..
What did was
install another random theme
then went back to the program and clicked change CSC again
this time when I choose the custom theme pack, I saw the "Try now".. after that I followed the instruction to about phone->legal and clicked on CHANGE Carrier Android 10 and VOILA!!! I got that CSC change page.. I saw XAA was selected and I changed to TMB... after that "Sales& Network Code Change" and clicked ok.. .The phone restarted and saw the T-Mobile logo!!!!
I even tried the *#272*IMEI# and this time it worked and showed me the CSC screen!!!
Hope this helps anyone who is stuck...My phone now says TMB/TMB/ATT!!!

Hello,
Prior to doing the process. I used smartswitch and backed up my phone completely.. I also did factory reset the phone.. *** Since I was going to use a new method/tool, I was not sure so wanted to make sure it does not interfere with any existing account/app on the phone. Once I was able to get to the CSC screen and changed to TMB, I went back again to make sure do a factory wipe and start complete fresh out. Hope this helps. Good luck!

hmm.. don't recall if it wiped.. I already had T-Mobile sim inside.. so when I saw the CSC selection page and as soon I choose TMB it restarted and came with T-Mobile splash Page, at that point I know it worked, so before even finishing up the boot process, I rebooted in recovery and did the factory reset

I had to do the CSC changing today and it simply rebooted and displayed the new CSC logo. It was with AT&T and when I change it to TMB. I get the T-Mobile boot logo.. I was able to get back in to the device without loosing any data.. The CSC showed TMB/TMB/TMB.. But I noticed the ringer/notifications sound still remained the AT&T settings. So to answer your initial question, my phone didn't get wiped out when switching the CSC.
Thx

I have found *some* Samsung models can still change CSC via firmware flash in Odin by following these pre requisites...
- disable find my phone
- sign out of Google and samsung accounts
- developer mode .... enable oem unlock
- flash a single CSC stock firmware in odin (do not use home-csc)
- phone will be completely wjped but after first boot and running setup, CSC will be change to match new firmware
Have any one tried

flash the CSC not the HOME_CSC. The CSC file will factory reset it and remove any remnants of the previous carrier info including bootanimation, splash screen etc etc

I know, and I did, and still shows KTC bloat including logo. I saw other people posting about the problem in other samsung device forums but didn't find an explanation. I wish there was a unified forum for these general samsung issues, so that they'll get the largest amount of attention possible.

Either the firmware being flashed is mislabeled, or it's not truly flashing. I've seen where Odin says it was successful, but not really... That could be a whole different set of reasons why it's not working though.
My suggestion is re-download the firmware, from a trusted source and try again.

often times the phone is being told what carrier youre on by the sim card, then if the phone has that carriers CSC in its internal database (in the case of multi-CSC firmware sets) the phone will recognize the carrier and then install the carrier specific crap. I use the U1 firmware and dont have any of the carrier junk that it originally came with. I got it on a Cricket offer and very quickly got rid of all the Cricket junk by flashing the U1 firmware
I successfully changed CSC to KOO on my G960N after it was SKT to do that i had to
- root the device
- install phone info app
- use the tool to change csc
You will have a choice of 4 CSCs choose KOO and install
PS : backup data as it will be erased

Thanks again for this help bro , i already forgot about the csc code changing , only thing who were annoying to me were the SKC blootware and bootanimation
i succefully uninstalled the blootware after rooting and using root uninstaller pro , then about the bootanimation i couldn't find any way to change (even by changing files into system/media/ ) , so i just left it
but good thing you gave us the steps , maybe it will help one guy who is willing to change his CSC code

i succefully uninstalled the blootware after rooting and using root uninstaller pro , then about the bootanimation i couldn't find any way to change (even by changing files into system/media/ ) , so i just left it
but good thing you gave us the steps , maybe it will help one guy who is willing to change his CSC code

Do a backup with twrp when you change csc it will erase data and you will loose magisk all you have to do is go back to recovery and restore the backup ( backup only data )
Twrpcan always be installed with odin with or without magisk
Alright bro , thx again for the help !
Hello everyone. So I have a S20 Ultra SM-G988N. Its a Korean variant with a Snapdragon Chipset. It has the option OEM unlock and all so the device is rooted. I also was able to change my CSC without doing a data wipe...
What I did was go into the root of the phone into /ets/imei/mps_code.dat. I opened that file with text editor. For me it came up empty so I added the text "KOO" with a different text editor because the one provided by my Root Explorer wasn't letting me edit it. Once I added that in I restarted my phone. My phone started up, had the regular Samsung Logo. But if course some of the blostware is there.
My big issue is the phone connects to Korean things as in some apps will say my Region is Korean. For example my Weather widget (Samsung App) would only let me pick location by state, or country. I can't choose the town I live in nor does the app knows my correct location. It would say I'm in Bethpage Korea.
So my question is because the SM-G988N has a Snapdragon Chipset, would I be able to Flash an U1 Variant Home CSC Using Odin? This way I have multiple CSCs which I can then use to debloat and get the phone to be like US Version.

I have a Korean G960N device that has a lot of KT carrier bloatware, so I decided to flash a KOO unbranded Korean firmware, however even after flashing is successful the device still shows KT logo, bloatware, and several KT-related options in the 'Settings' app, as well as KTC in the "about device" option. how do I get rid of this ****.

I successfully changed CSC to KOO on my G960N after it was SKT to do that i had to
- root the device
- install phone info app
- use the tool to change csc
You will have a choice of 4 CSCs choose KOO and install
PS : backup data as it will be erased

Thank you for your share. I did the same process as you, but in the phone info app, when i select "Change CSC" it deliver this message: Try opening secret code... then nothing shows up. I'm glad if you could help
THanks

yes it works, I did the same on an S20FE Korean version, Root + unlock BL needed though.

if i want to flash in KOO Flash pack, is it necessary to unlock bootloader and root? Is there any way to be able to root without losing Samsung Knox?
Need some help guys. I am based in Australia and swapped an iPhone for the Z Fold 3. Went through the usual connection process with my sim and esim whilst connected to wifi. All was well as it allowed calls and received calls when I was home. As soon as I stepped outside my home where it was trying to use the network, it does not work. It keeps saying not registered on network. Tried to manually select network via settings, checked all APN settings from the network and all is ok. Even tried 3 different carrier sims (Vodafone, Optus and Telstra) yet still no matter what this phone will never connect to any carrier network without wifi. From there I tried 3 different firmwares from Sam mobile just in case it had corrupt firmware. Both android 11 and 12 will not work. Need help guys please. Any suggestions?
Two options
1. Get into recovery and do a factory reset
2. Flash the latest firmware ( F926BXXS1BVB3 ) , firmwares are now Multiregion so no problem with that

If that doesn't work , maybe you lost your EFS partition ( it contains your IMEI info ) and that is a big problem
You will have to read a lot here @ xda to try to recover it ( if it'spossible somehow )
Thank you kindly for the information and reply as it is really appreciated.
I can see both imei numbers on the device if this is what you mean? Ironically when the phone is on WiFi with WiFi calling enabled and the simcard plugged in, it allows me to make calls with my number sending to the recipient, it just won't do the same when the WiFi is disabled, I can not communicate out by data nor voice and it keeps saying "not registered on network." I have checked and the phone is not network locked and is clear for use. I will try the firmware link you have sent however if this does not work, may I ask what you think may be next?
To add I have tried various firmware which did not work either.
Can anyone help with this as the above unfortunately did not work.

When you flashed stock firmware , did you use CSC or HOME_CSC ?
You have to use CSC , to get a fresh install
If possible , once flashed get into recovery to perform a Factory reset from there , maybe this can get back the EFS partition that seems to be corrupted
again ... DON'T use HOME_CSC

Thank you for your reply. I did use csc and followed all your instructions. Unfortunately still the same. I am so lost as to what to do as I love the phone but can not seem to fix it.
