Hello,
Since 2 days I got really really bad gsm signals (wifi is fine), when I get some I just have maybe 20% max, so I can't make or received calls only sending texting but I can get 4G+ which is working fine.
I didn't dropped or anything special with my phone.
I was using ozcan rom so I put a stock rom 5.0.2, still issues, try updating OTA, still issues.
Before flashing stock rom I wipe data and partition with the official recovery.
I try to put a different sim card still issues, my sim card is working fine on an other device...
Any idea ? maybe something to try with the "modem" should I try to extract it from my country from a stock rom and reflash it with odin ?
You are my last hope
Thanks
Hello.
Go to settings, backup, format system (or wipe).
Then pull out battery, get it back, go to recovery and wipe data, wipe cache.
Turn off, then power and go to download mode.
Download latest fw for your CSC, download odin, download PIT file for your CSC (sammmobile forum - galaxy alpha, first post).
Then open odin, plug your phone in download mode.
In odin select PIT - choose downloaded PIT.
In odin select re-partition.
In odin select AP - choose downloaded fw.
Then click start, it will ends with PASS and you will be OK.
thanks for your reply
But I can't find the pit for my csc :/

Sorry I don't want to bricked my device
Thanks

If you're using N950F with single SIM, it's possible to change your phone to dual sim if your phone is non-rooted.
You cannot do this by yourself, there are enough discussions in terms of this,
I have converted my N950F to dual sim and tested, working well on both SIM cards, VoLTE looks only work on SIM1
I'm looking the sim extension cable, I have already bought dual sim slot from ebay, but you CANNOT use sim 2 and SD at same time,
Otherwise you need DIY your SD card and SIM card, I cannot do this because my second SIM card belongs to another country, I cannot get new card if the old one got damaged.
So I'm looking some SIM extender cable.
There are 2 solutions for this,
1. Copy the IXXI to SIM2, some country will restrict same IXXI on the network, duration: approximately 2 hours, remote control 1 time
2. Using 2 different IXXI, but the original IXXI will be lost, they will give you 2 new IXXI for both SIM cards, duration: approximately 3 working day, remote control 2 times
If you need keep the current CSC, please use oreo AP/BL/CP and your home_csc file from your country rom.
I have tested, all good, VoLTE is working well.
If you need change the csc to another csc, normally change to the different csc but in same country, for my case, I have changed my csc from VAU/VAU/VAU to XSA/XSA/VAU.
I'm on vodafone, the VoLTE is still working after CSC changed, so don't if VoLTE is working on XSA with carrier vodafone.
How to change the CSC in same country:
You can just change to another country, then flash your home country firmware back, I have tested, the default csc will be changed to your home csc, even you take your SIM card out.
The only way with unroot is using the combination rom, see steps below (source)
Prerequisite:
*Battery at least 50%,
*Remove SIM & SD Card.
*Important- BACKUP
*Odin 3.13.1
1- Download the latest Combination file,
Google COMBINATION_FA71_N950FXXU3ARA2_CL12771072_QB16471415_REV00_user_mid_noship.tar or COMBINATION_FA71_N950FXXU3ARA5_CL12991683_QB16751804_REV00_user_mid_noship.tar
2- Flash your home country firmware, if you didn't flash to any other firmware, you can ignore this step.
After flashing the official ROM, Do a Factory Wipe.
3- Flash Combination file you downloaded in AP AND your country HOME_CSC file from official ROM
4- After successful flashing is done, wait for the phone to boot up, it will go in to diagnostic/Factory mode, don't panic.
5- Tap Factory IMEI and enter the code *#243203855# ,it will show you list of available CSCs, choose the one you need and tap install (I remembered there is 2 options, I selected the option with full).
6- Just in case, do one more Factory/Cache Wipe.
7- Power off the phone & enter download mode and Flash it with your country's officlal ROM. Four files (BL+AP+CP+CSC) Use CSC, don't use Home_CSC.
8- Knox Zero. System Status: Official
9- You can check your active CSC in recovery mode or use Phoneinfo app.

Really...
I didn't test the new ROM, I'm using ADSL which need download the ROM overnight, and don't want to backup and restore again, that will be 3 hours..
I'm waiting Oreo ROM for my region, then I can get Samsung pay and VoLTE back

The N950F and N950F Duo uses the same firmware
If i flash this via odin, how can i change csc back to original (my csc is THL)?
Downloaded via SamFirm . I'm on TPH (Portugal). Should I flash only AP as per sammobile instructions?
Instructions
Extract (unzip) the firmware file
Download Odin v3.13.1
Extract Odin ZIP file
Open Odin v3.13.1
Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
Connect phone and wait until you get a blue sign in Odin
Add the firmware file to AP / PDA
Make sure re-partition is NOT ticked
Click the start button, sit back and wait few minutes
Thanks in advance.
Hello, one noob question, if I flashed this fw, will I lose all of my data after flashing it? Thanks

You will likely have to wait 7 days for the option to appear, then you can toggle it to unlock the bootloader.
Soooo, flashed with CSC instead of Home CSC to get a full wipe and try to change stuff around, yet i am still at the old CSC, and i mean completely (MID/MID/MID). I fear i wont receive OTA's in the future now, but how the hell did i manage to do that?
At least i got Oreo.

Witch of the 5 firmware files did you flash?
EDIT. Answering to myself and everyone interested. Flashing AP, BL, CP, HOME_CSC works fine and leaves data intact. Done it.

Thanks but it's supposed that the oem unlock option only appears when the csc code match with the local SIM.
I did the factory reset but I still having Arab Emirates csc and I'm from Chile.
Dialing *#1234# I get this one csc: .....oxm.... what does mean?

Did you have oem unlock before you flashed/reset?
OXM is a multi-CSC, and if your home country isn't included in that package then I don't think it would change to Chile.

Chile has like 5 CSC, one of them is "open". So, the question is: can I flash this firmware without problems or I have to wait to get the OEM option? If I do that, the SIM card must be on the phone or not? And, What happen if the OEM doesn't appears?
Sorry if im bothering but I don't want to mess up my phone.
Thanks in advance.
Hi i want to change CSC for my S9+ G965F/DS
My actual CSC is CAC/CAC CAC/PHN
CSC : G965FOXM2BRJ3
I tried to flash combination rom with odin but it failed
download odin 3.13.1., i've attached it below
extract it and run odin.exe as administrator
download the rom you want from sammobile
use HOME_CSC if you want to keep your files, otherwise flash the second CSC file
i think this should work
You will need sim card from country to wich one you wolud like to change CSC. OXM is universal multi CSC,and when you put that sim from that country it will ask you to restart phone and after that just do a factory reset and csc will be changed.Its only way without playing with combination files.Sorry for my english.

This is pretty much the only way to do it now with the OXM multi-CSC.
Tried with UK sim but phone doesn't tell me to reboot or anything, i have the same CSC
Hi, I'm trying to change my CSC to XME (Malaysia). I downloaded the files using Frija. After flashing, my phone's CSC is now XXV (Vietnam) instead.
`XXV/XXV,XXV/EUY".
Note that I am unrooted and I'm trying to change the CSC region by using official firmware so I can still keep my Knox and warranty intact.
Wondering where did I do wrong? Help is greatly appreciated.
Update:
I've managed to change my CSC for Android 12.
When you flash a multi CSC firmware, it seems to be defaulting to a CSC which in my case, is the Vietnam XXV CSC.
I found a free tool that could change the CSC called SamFw FRP Tool 2.5
All I need to do is flash it with Odin again and when the initial setup screen shows up, go into an emergency call and type in *#0*# which will take you into the test mode.
After that, use the tool to change CSC with the tool then complete the rest of the setup on your phone.
P/s: Samsung Pay does not seem to work. When I add a card, it says invalid information when authenticating with the bank.
Hopefully the FRP tool is from a reliable source. The error message could mean the opposite. Normally the CSC from multi region is selected by the SIM cards country. Did you have 2x Malaysia inserted on first boot after flashing? Also there are dialer codes that bring up a menu to select a specific region, I think best chances are with Google phone app. You would need to search for these codes for your device.
Samsung Pay in german, CSC is EUX fix, 5 minutes
Hello This also works with most Samsung phones If anyone is struggling with Samsung pay being in German and has the csc being EUX, I know how to solve the issue and it only takes about 5 minutes. Basically the csc is set to EUX, which is the new European standard, but for some reason, Samsung...
eu.community.samsung.com
Another update, Samsung Pay works after I register with another bank. It was the old bank's fault. Not the phone or CSC region change. The CSC region change worked for Samsung Pay as well from the very begining.
