[adi1adit123]

Check their vodafone website if they support volte on ur device. usually regions matter too.

All worked perfectly well, but does this mean i wont get software updates anymore? . it says failed to register device when trying to search for updates.

Volte is supported in my region but not on my device. Confirmed via text message service to verify the same. But does this mean that no Note 8 will have volte working on Vodafone India network!

Please check voda website.. it doesn't list note 8 under compatible devices.. (weird.. even s6 is listed) when they do, it might get volte automatically or you need to flash a newer omc zip taken out of newest ROM. Let's see when they support the device.

Updates generally rely on CSC. Our csc doesn't match with baseband. 955F vs 955U.
You'll need to flash manually.

Not working on S8

Ok so I did all the steps and used patched odin to flash the stock firmware and then sideload SEC file again through ADB. After reboot the phone is giving me a persistent popup which says :The process com.android.phone has stopped". Although I can see volte in background but moment I close thispopup the mobile signal goes awa.

Hello nimms

Thank you for the response. Can you please tell the procedure to extract the omc zip from FW files of Indian variant Note 8. It would be great to know this procedure.

Thanks

So incase there's a new update, we can flash the original rom and sideload the sec_omc again to get it working?

Flash AP CP BL now via odin and then omc zip via adb again
Please read the first post in full.. it's there in possible glitches.

Tried the steps (new instructions, dated July 10th) and it all went well until the very last step, i.e., while sideloading CSC via adb, got the following error:

E: footer is wrong
E: signature verification failed
E:error: 21

Kindly help.

Thanks in advance

That means the file was modified. Either you are using another file or you did something to the file you downloaded(adding or deleting stuff). Samsung signature gets void on modifying..
Or you have a corrupted download. Download again.

I tried both the files you specified in post #1, i.e.,

========
Then during part 2, instead of "Add CSC Systemroot" file, use the modified file with India and XAA-USA CSC
This will flash INS CSC along with XAA CSC. This zip was made by @jrkruse for US carriers... I've just added INS CSC to it and removed other US carriers stuff.

Or.. If you just want Indian CSC Use this file (no XAA) https://drive.google.com/open?id=0B-...FhFR2NtRHc3ajA

=========
And a noob like me cannot modify the file. Is there some other file I should use as CSC ?
My phone is snapdragon S8 on BL4
Does the phone need to be rooted ? I assumed no whilst reading the new instructions (of jul 10)

 

[guestx00150]

I just re-read all the instructions again and sure enough, I did all and didn't miss any step or did it wrong.
By any chance, does the foll. step hold true for USA snapdragon s8 or needs any changes ?

16) Type in echo "INS" > /efs/imei/mps_code.dat (Please make note of the space between " and > and /)
You won't get any confirmation.

Also, I used the stock CSC in foll. step. Is that correct?

17) Now flash the full Stock firmware matching your bootloader via ODIN (BL, AP, CP, CSC files (not home csc)

You followed old instructions first it seems.


Do 20 steps and read possible glitches section if there are any issues.

No, no. I followed only new instructions
And it all worked well until step 19

Only during step 20, I'm stuck and unable to sideload CSC zip

 

[nimms]

The zip to be sideloaded is Sec_omc.zip (specific to your model)
You are trying the wrong zip from old instructions.

True. Thanks a lot. It works now.
Somehow in instructions, I took CSC zip not some as Sec_omc.zip
I guess that's where noobs like me bother seniors like you but you guys extend help always.
So, a big THANKS and sincere gratitude for such a great tutorial.

 

[ssm227]

Guys thanks a lot for these instructions, I got VOLTE on my S8 9350U1.
I observed two issues so far
1) Message force closes, but I installed Google messaging app and no issues
2) Samsung Pay isn't working, I'm able to add Indian cards and activate as well but transactions dont go through, and also inside app it shows offline. I tried to uninstall and reinstall the app but didn't help
3) Some apps still redirect to US sites, eg. I was trying to install FoodPanda and it shows the US version even though my Playstore region is India. I tried to Add Amazon Pay in Swiggy and it takes me to amazon.com for authentication

Any help please?

S9 files please?

NEW Instructions: Dated July 10th 2018
Should work on all Snapdragon USA/Canada models (ATT , verizon, sprint, tmobile tc) Tested on S8+ and S8, should work on Note 8 and S9 if you have right files.

Keep your Jio SIM in the phone all along.
Check your Bootloader version first (Download matching files only)

(Identify your bootloader version > Go to Settings > About phone > Baseband version under software info should show something like G955USQU4CRE9 The fourth number from right is your bootloader version. If you try to flash any lower version (BL 3 to BL 2), ODIN will fail and phone will show Fused 3 binary 2 error. So, choose the file versions matching your bootloader. You can go higher but not lower. Means BL 2 can be flashed with BL 3 or 4 but not with 1 (most of the times).

1.Back up your data using Samsung smart switch or any other means (save whatsapp chats to google in settings)
2.Flash matching stock firmware (On unzipping stock FW, you'll get AP, CP,BL and CSC files. Use Odin to flash them) (Don't flash User data file if it's there in extracted files)
Recommended Odin https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572

S8+ models
CRE2 for BL version 1, 2,3 or CRE9 for BL 4
S8 models
CRE2 for BL 1,2,3 or CRE9 for BL4
Note 8 models
BL 1,2,3 or CRE1 for BL4

3. Download sec_omc.zip specific to your model
INS OMC for s8+ or For Note 8 or For S8

4. Download and unzip combination rom (You'll get a file ending in tar.md5) (Matching file only)
For s8+ models or Mirror

For s8 Models

Note 8 combination files or Mirror or BL 4 version

5. Open Odin (princecomsy version) and click on AP, choose the file you extracted in step 4
6. Put your phone in download mode (hold the Power button, Volume Down button, and the Bixby button until Download mode screen is seen. Press Vol up to confirm).
7.Connect your phone to PC. You should see "Added" in log of Odin and see a com port appearing on top left.
8) Click on start tab. If everything goes well, you'll see "PASS" on top left. Let it boot to Factory binary once.
9) Boot your phone to recovery mode (hold the Power button, Volume up button, and the Bixby button until samsung screen is seen).
10) Install "minimal ADB fastboot" program on PC, Copy the sec_omc.zip to your minimal ADB folder on computer (under program files on C drive).
Double click cmd-here.exe in that folder.
11) Connect your phone to your computer with your USB cable and in phone select Apply update via ADB in recovery screen (Navigate with vol bottons and select with Power btn).
12) On ADB window on PC type "adb devices" without quotes. Next line should show a device attached
If seen, type "adb sideload sec_omc.zip" without qoutes. It'll start transferring the file.. check mobile screen it'll install itself. (you might see some errors)
13) Once your phone reboots, you will see an "IME" button on the bottom). Tap on it and type *#243203855#
14) On resulting window, if you see INS in the list, click over it and click install and select full customisation.
15 Your phone will reboot to the 'factory binary homescreen', go to ADB on your computer and type in "adb shell".
16) Type in echo "INS" > /efs/imei/mps_code.dat (Please make note of the space between " and > and /)
You won't get any confirmation.
17) Now flash the full Stock firmware matching your bootloader via ODIN (BL, AP, CP, CSC files (not home csc)
18) After the flashing, phone will reboot. Don't setup any accounts yet. Boot to recovery and select "apply update via ADB" (Like step 7)
19) Sideload the CSC zip (similar to step 8) and let it reboot.
20) On reboot, you should see INS/INS/xxx under software info (xxx is your factory csc version) and VoLTE icon should appear.

Possible glitches
1. Phone app force closing
Reflash AP BL CP only excluding CSC
Install OMC zip via adb

2. Sprint OMADM app needs to be removed to avoid annoying notification or change notifications to low priority
To remove via ADB, turn on usb debugging
type in adb shell
you should see a dollar sign.
next type in pm uninstall -k --user 0 com.sec.omadmspr
it should say success.





IGNORE the following
Old instructions with old files

This is specifically for indian carrier, JIO 4G.
Now that root is available, We can install S8 india CSC and get VoLTE on USA-Snapdragon sim unlocked phones.
First root with the help of this thread till Part 1

Then during part 2, instead of "Add CSC Systemroot" file, use the modified file with India and XAA-USA CSC
This will flash INS CSC along with XAA CSC. This zip was made by @jrkruse for US carriers... I've just added INS CSC to it and removed other US carriers stuff.

Or.. If you just want Indian CSC Use this file (no XAA) https://drive.google.com/open?id=0B-Kp4aJsfti2NFhFR2NtRHc3ajA

Download only one of the 2 files please..

Order in flashfire should be Wipe > System.img.ext4 > QG2_ADD_INS_CSC_SYSTEMROOT.zip

It might take a few seconds to acquire signal. if not, try toggling aeroplane mode off and on, then see.
VoLTE is working for me. (I have a sprint version of s8+)
If still fails, make sure you have Jio Sim in the phone while you are doing this procedure.

Credit goes to respective thread owners to whom i linked (Root team and jrkruse).

Thanks to @jrkruse for the idea of flashing CSC zip from exynos to snapdragon
@Mike15678 for carrier switch thread
@chetan180 for trying carrier switch to INS
@anarasgarli for combination files links

I'd be really grateful if you could provide the files for Galaxy S9 too. I have one lying around and I'm unable to use it due to the lack of VoLTE
Please help
