Lost LTE and VoLTE after flashing a new rom with Odin - Samsung Galaxy S9+ Questions & Answers

Well guys as the title says, yesterday I flashed the April security patch (because i was tired of waiting).
But when my phone rebooted i realized that I had lost my LTE connection, only 4G left. Also no more HD voice calling.
Any thoughts?
If I perform a factory reset will it be back to normal?
Thanks in advance

Anyone?...

If you flash to different country's CSC which is not your country's CSC, VoLTE won't work.
Example: You flash to BTU (UK) firmware, but you're in Germany and using a Germany network operator, your VoLTE won't work.

When checking *#06#, it gives me my correct imei code
But when testing *#0011#, i got IMEI Status: NG
What does NG mean and if it is a problem,how to repair it
Did you flash any firmware? Doesn't usually happen randomly. If it has should send to Samsung.

I recently updated my firmware to 6.0.1 and found out the GSM option is not available and cannot be registered on any available network. I didnt make a backup of the working firmware. I downgraded to 5.1.1. and now see the GSM option but still cannot connect to the gsm network. I checked the IMEI number it is fine but when I type #*0011#, I see IMEI STATUS:NG. I am not sure what NG stands for. Could you help me please as I am sitting with a phone that cannot make calls and receive sms.
Thank you in advance.
I'm into the same situation i upgraded to 6.0.1 no i ain't got network...

I tried so much things, I flashed so much firmwares and same.. the last i did was flashing 4 files + pit but again the same..
The problem appeared when updating from 5.0.2 to 6.0.1 via odin. I dont know how to downgrade and test again bc every time I try with odin gives me a fail, maybe its a block for downgrading

I had the same problem, If you have you EFS partition backup. then you are lucky. just restore EFS partition from recovery (TWRP in my case). :good:
If dont have backup:crying:. but have your original IMEI no, try editing IMEI (search google how to)

The only thing i can suggest is download samsung phone info app from play store. Go to CSC, check what the origional CSC was. Find and download and flash back to the original CSC. Theres not much you can do with lost or corrupted efs. The same happened to me when i flashed my nandroid backup. I had not backed up efs but after flashing origional stock my imei was repaired. Good luck keep me updated
Or one other thing...flash a branded firmware of the network you use with PIT. The PIT might fix the efs partition.

Do you lose OTA updates once you flash this UK ireland firmware for example? Do you need to factory reset/root/install twrp or Odin is enough?

Odin is your friend, no need for root or twrp. OTA will work. I live in the Netherlands and dirty flashed the unbranded UK/Irish version on my son's G925F, which had a Nordic Marshmallow version installed. Worked fine. The Vodafone branded version for the Netherlands did not work, but maybe I should have removed the SIM card first, since this was no Vodafone SIM. You can change the language into any language you prefer.

I bought mine in Denmark, so Nordic version as well I guess, but I never tried using Odin, can you provide some more info? Do I need to factory reset or it keeps all my data, I am also on Marshmallow (G925FXXU5DPL5 baseband), It's Unlocked, any sim works in it.

If you go to the firmware page of sammobile you will find the instructions for installing and using Odin. It's not complicated. I did a dirty flash and that went well. All apps and data were unaffected.

[HOW TO] Install OREO on EXYNOS Note 8 [ Unrooted]

Well I saw the update in France [XEF] yesterday and wanted it right then! So I searched all the forums and finally found a good way and now my unlocked Galaxy Note 8[NON Rooted] is running Oreo with INS CSC.
Made this guide so that people can find this method easily.
Keep in mind that flashing your device is always risky and I DO NOT take any responsibility if you mess up the procedure and damage your device.
Method:
>
Download the latest BRB2 Firmware from here https://updato.com/firmware-archive-select-model?record=67BFD0E620FF11E89F15FA163EE8F90B OR https://www.sammobile.com/firmwares/galaxy-note8/SM-N950F/XEF/
Flash it using Odin[3.12.3] [ MAKE SURE THAT ONLY AUTO REBOOT & F.RESET TIME options are checked in the 'Options' tab of ODIN]
After flashing is complete reboot into system and run through the setup, after that remove your SIM & SDCARD and open the phone app. Dial *#272*YOUR IMEI NUMBER# to open the list of CSCs. [to get your IMEI dial *#06#]
Select the XEF CSC, it will ask to reboot and reset the device, let it do the same.
After the device reboots then check for software updates manually and you'll get OREO.
After installing oreo put your sim and sdcard back in, it will tell you to reset the device, DO IT as its necessary to restore your original CSC.
That's it
Now you have OREO, Non rooted and stock oreo.

change csc from UAE to MXO

Hi all
I have some doubts about changing the csc, I've been looking on the web and here but still have massive doubts
I have a n950F/DS with OXM csc, currently pointing to UAE, cannot make samsung pay work, my cards are mexican.
so far I've understood this about the process
1.- downloaded odin and the bellow firmware from sammobile
Product code MXO
PDA N950FXXS3CRF1
CSC N950FUWB3CRE3
2.- Install MXO firmware by adding all four files, using csc file instead of home_csc
3,- let it boot and set up device, with out sim
4.- flash OXM firmware, all 4 files
5.- let it boot up with sim inserted and set it up.
I think those are the steps to make samsung pay work for my region but still not sure
Please let me know if I'm wrong, I really want to use the full potential of this phone.
Do you think is better to stay with MXO insteam or OXM?
thanks
I've changed mine twice now, once to o2 firmware and then to three firmware both for the UK on a 950f without any bother I flashed all 4 each time and used the home csc and all works well here

thanks for replying,
let me see if I understand, I need to flash the whole 4 files so I can change csc? when to use home csc?
could you help me with the steps?
thanks!
I downloaded the firmware I wanted from updato and used Odin to flash each of the 4 files so I would have a phone as if I'd bought it from 3 network so I could use wifi calling and 4g calling
This is what I have now after changing to it

home_csc file, what does it do? is that the main one to force the csc to change? or do I always have to use csc_ file only?

I have a similar issue but I want to change it to full XEF instead of "XEF/XEF/XSG". Can you guys detail the steps I should do ?

S9+ XSG MODEL (UAE) won't receive pie update

I have had this update right after turning it on for the first time, but since I insert my local sim card, it forces me to factory reset it.
Since then no update.
I contacted Samsung & they say: "you must insert a UAE sim card which is activate and working, then factory reset the device to register it back to it's original
software provider. otherwise - no pie for you.
I am not in the UAE and have no way to get such a sim card.
Just factory reset won't help much.
Any help ?
