S9 Bootloader, CSC, VoLTE

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.

A5 2017 imei

Hello, I bought a used a5 2017 phone from ebay and when I received it, my sim not worked, then my brother's sim either. I think the imei is being blacklisted. Is there any way to change it, or how?

Someone know how?? I have never used Odin.
Here is a tutorial on the web for an older version: https://skipsoft.net/flashing-a-single-partition-i-e-system/

If the baseband version/ids/content in *#0011# isn't there, try
restarting the device?
changing firmware, preferably with a newer modem?
wiping data?
For installing firmware, there's odin. Use odin, the stock rom (official firmware), and samsung drivers, Insert the usb cable, switch off the device, hold power+volumedown+home(the button on the middle), grant its permission, select the stock rom in odin, start. New firmware might require odin 3.13.1. The error "failed: device _ binary _" means that the firmware is old, somewhere in the middle of the firmware version code is for example U5 or S5, if U6 or S6 is already on the device it won't install u5/s5.
To check if the device is blacklisted, the code is *#9900# > run cp based log > copy to sdcard. Select nothing else. It is available in the folder /sdcard/log/err/ , sdcard meaning internal storage or device storage or internal memory. Open LitmusLog....txt and scroll down, look for the part that says reject info list, look for Cause:6 (basically this device can't be used); Cause:3 (basically this device can't be used with this sim). It is also available in /sdcard/log/err/ss_log/*/cp_members.txt , but the reject cause is in hexadecimal, and resets after a reboot, compared to the other file that keeps reject causes until it's replaced or cleared in another menu. For more info contact your mobile network operator.

Sadly this not helped, the imei is blacklisted, and modem update not fixed it for me. :/ I contacted the network operator and because I'm not in contact with the person who sold me the phone, they can't tell me anything, because I don't have the rights. So I think the only way is the imei changing method, but I don't know if it's even possible or how.
Sorry if my English is bad, and thank you.

I did a bit of research....
- it is illegal to change imei- if hat means anything to you, lol
- it is against Ebay's policy to sell phones with bad imei
- there is an xposed module to change imei but you would trip knox

I think in my country it's not illegal, but not quite sure.. And i didn't know this, the guy wrote it down in the ebay ad even, so it went through.
Thank you, I will look into it, but I think I will sell the phone as a 'working display part'.. Motherboards are not cheap.

It's perfectly normal except you can't use a sim card? Or is there more things wrong when imei is blocked?

Imei is locked to the device as far as I know. This is why a device can be blocked after being reported as stolen. If it is imei blocked then you should get a refund or make sure Ebay is involved if the seller refuses to.

Baseband not found IMEI unkwon

Hello everyone, I have a Moto Z2 Force XT1789-06. I had updated the firmware and after that the phone is working but the baseband is not found and the IMEI is unknow and of course there is no wi-fi and no carrier signal. I have already tried to flash the original retail firmware and it can be installed accurately but the baseband and IMEI are not identified.
Do you know how can I repair it?
Thank you.

Well I had the problem of baseband not found but I could solve it, I still continue without a mobile network although the IMEI does appear. The only thing I did was update from nougat to Oreo. The phone is the AT & T variant and is unlocked for all networks. Any solution to have mobile network again?

Have you tried installing the latest version of the AT&T OCSX27.109-47-14 firmware? It also happened to me not to have a telephone network and wifi. It is caused by the wrong NON-HLOS.bin file.

Yes, that version is the one that installs first now I am with the OPXS27.109-34-15. I'll try flashing the stock ROM maybe the problem is solved.

I managed to get myself in this situation this weekend... When I start my phone in fastboot mode it shows "baseband <not found>" and when I start it I get no wifi or network.
I've flashed almost every Retail firmware from this repo to no avail: https://mirrors.lolinet.com/firmware/moto/nash/official/RETAIL/
Any particular version I should be installing perhaps? Could I install another version that is not retail? Mine is the -05 variant.

Can't update to Android 9.0

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.

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?

Emergency calls only. HELP!

Hello
I bought a used s9 a few months back. It had dual sim. In "about phone" it said G960F and was on android 9. A few days ago, I wanted to flash android 10 so I downloaded firmware for G960F, booted my phone in download mode and SURPRISE. The whole thing was in Korean and of course it was a G960N model. So I downloaded firmware for G960N this time and flashed it. Everything went perfect but when the phone booted up, It had no sim service.
I've tried everything I've found on the forums so far related to emergency calls only or no sim service.
Any kind of help would be appreciated. I have no sim service for 5 days now.
Things I've tried so far:
Flashing my phone again with android 9 stock firmware, which I can't do anymore as I've updated the bootloader lol.
Flashing custom roms
Changing csc from SKC to KOO
Flashing OXM CSC as I live in Pakistan
Flashing different modems and basebands
Nothing worked

Try flashing back a G960F android 10 firmware.

contact the seller and ask what the hell have you bought (if it was any variant of the S9 at all.. somehow I doubt it).
2nd: write down the IMEI and serial number, and check with Samsung if this configuration ever existed (if not, what I suppose, the IMEI/sn info about the REAL model can give you a hint what have you bought).
Having the above info in hands, find the "service firmware", 5 files ROM for your device and try to flash it.
If it will not work still, I'm afraid you have two options:
1. check IMEI against stolen devices with your carrier.
2. Go to Samsung service asking for help.

Well mostly it isn't a fake mediatek phone as it will not even have a download mode.
Probably he bought a shi**ily refurbished phone with it's internals mixed from multiple versions of the s9, in the best case.(a Frankenstein variant of the S9)

I'm going to solve this mystery for both of you. The phone he bought is indeed an S9. Here in Pakistan, 'software' guys in shops can convert these to dual sim models with some z3x and Chimera f*kery.
As for why his phone isn't working - it is because the phone had a tampered IMEI to bypass local custom charges levied on all imported phones (insane charges, doubles the price of these kinda phones). Once he flashed a new image on his phone, his IMEI status would have become NG instead of OK, which prevents the phone from accessing any networks.
Solution is to visit the same 'software' guys, ask them to 'patch' the phone. It is a 5 minute process, requires root (which these phones already have).
