This is to confirm VoLTE and VoWiFi is working fine with STC Saudi using India-Volte-Vodafone very fine. I've even tried to make a call while in airplane mode and it worked fine.

I for the life of me can't get anything to show in PDC after following this.
After entering the setprop cmd, I go to PDC and there isn't any device in the drop down.
Any ideas?

Hi kesn
I managed to enter PDC using this method and change my carrier profile.
However, it still doesn't work for me.
It keeps the "Oversea-Commercial_DS" profile even after I activate a different profile.
Do you know how to solve it?

Hello, I am not an expert on the subject, but when I did all the steps as called, there was no problem. I can recommend running Pdc as administrator, canceling the oversea profile correctly, selecting the profile suitable for your operator and activating it after the "pendign" text.

I have managed to make volte and wifi calling working with Freedom Mobile (Canada) on Oxygen OS 11.0.2.2 OP8PRO (Android 11). Both sim cards are in use, lte switches from data sim to freedom sim during the volte call which is pretty cool.

I am also on Freedom in Toronto. How did you get volte and wifi calling working. I have volte and wifi calling enabled, but it's not working.

 

[dearshakya]

the above mentioned method does not work for me. My set is OP7T currently running on OOS 11 stable version. I tried but at PDC side, it says (QMI connection not ready, please use USB driver version 1.00.32 or later and fix the connection before using PDC tool). Previously it was working fine on OOS 10. Help.

Hi, could you please confirm if volte and wifi calling on Freedom mobile are still working for you on your OP8Pro with the latest software? I am looking for a new phone and will probably go with a OP8Pro if i can confirm that it will work well with Freedom.

 

[bcmike11]

So I got the OP8 Pro and I'm on 11.0.5.5.IN11AA (no root) with Shaw/Freedom (Canada).

I got PDC working but there is no profile for Freedom. Other guides say I need to load the profile from a Pixel 4 with EfsTools.
I spent a long time trying to get 'EfsTools-0.10-modded-1.2' to work but kept getting 'critical error Bad command' messages. Then I tried 'EfsTools-0.10-modded-1.1' which worked for me. Even though everything seemed to go smooth I still haven't been able to get VoLTE or VoWifi to work at all. Did I do these steps correctly?

• in PDC I changed to the 'Commercial-TMO' profile and confirmed that it stuck after reboot.
• I copied the 'mcfg_sw.mbn' file from 'Pixel 4 android 11 mbn\Pixel 4 android 11 mbn\mcfg_sw\generic\Pixel\NA\Freedom\pixel_VoLTE' into the EfsTools folder prior to running the commands in the Efstools guide, which seemed to run without error.

I also confirmed that the same SIM in a motorola E5 play works with both VoLTE and VoWifi.

Hello guys,
Now that we're getting Android 12 update it seems the same issue is happening , No VOLTE & even 5G has disappeared on my OnePlus 8 pro has anyone got any idea how to fix this ?

I managed to fix 5G issue temporarily using Samsung band selector but it resets after restart & doesn't show in settings anymore.
My network is Bell in Canada.

Owner of op8pro here... I tried to follow android 11 instructions to enable volte and was not able to get to factory mode (adb reboot ftm). But I managed to unlock engineering mode to turn full port switch in order to interact with pdc etc...

The biggest challenge for me being in freedom mobile is volte is not even an option in sim settings , I used to enable it by side loading logkit app but this method does not work in android 12 probably because system APK signatures have changed.

Besides that very happy with 12 in general, it appears bugs related to dual sim were finally resolved.

Happy to share more details with what I was able to accomplish but looking for advice on enabling volte via logkit or other method , except root.

Cheers.

Hey Asher,

How did you manage to connect to PDC ?

If you can share i can try to edit the profiles & see if any of those work with our networks?

Cheers

Hi Gk0001,

I followed this guide: https://forum.xda-developers.com/t/secrecy-unlock.4365059/

Most importantly to make it work I had to patch Sec5.exe. offset 32BF90h: 00 -> 01 to make it work. After that I was able to get to engineering mode by typing *#649010# and to unlock any option You need to enter Confirm code which is 6776 .

Once I enable full port switch I was able to run PDC, see profiles and change to UK_Telefonica in order to get Freedom Mobile VOLTE to work, but again, VOLTE is still down for me because of the global option for VOLTE for this sim is not available in the menu.

If you need details or patched sec5.exe PM me or I can post it here.

Andriy.

Thank you !

I am having issues with the unlocker it doesn't seem to show the numbers for me to get to the next step, I think I'm missing the steps you were mentioning, how can I patch from 00 to 01 on sec5.exe ?

 

[ansher]

Gtk0001, you need to patch the executable called sec5.exe using hex editor at the offset 32BF90 where current value is 00 and you need to replace it with 01 to make it work with oneplus.

In case you are not familiar with the hex editing, I have uploaded patched package below. Let me know if it works for you.

Couple of things to consider:

1. The guide tells to connect to ADB using wifi, forget it - just connect using USB (USB debugging ON) , so much easier.
2. When you open sec5.exe , screen is divided by left and right. When you click "unlock" button, on the left part you should see you phone serial number appear, this means connection is established, wait until you see OK flashing on the right side of the screen then press "Stop Unlocking".

Thank you very much for the file.

I tried using it & hit unlock but nothing seems to be happening I don't see my phone's serial number or anything else on there just blank not sure what step i'm missing?

I'm connected with a USB cable with USB debugging on from developer mode.

Folks, I know it is a bit late in the game to share the guide but I will do it anyway.
This worked for me on Android 11 stock OnePlus 8 Pro with Shaw/Freedom. This is not my guide but a reasult of the research and connecting several guides together, so all credit goes to community !
I have no responsibility for bricked phones or any loss as a result of following this guide.

2. Guide:

1 Enter these commands on the CMD screen.

Code:

13 Upload MBN file to the phone

EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -v

If you are using SIM Card Slot 2 run this (I never managed SIM2 working with Freedom VOLTE):
EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim -s 1
EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -s 1
