new update, this morning my 6t has Volte symbol and I tested with a call and it stayed on lte while in call.

So in between the 5 days or so since after doing this process with no more changes on my part, Im guessing it was my 6t line being provisioned in the background and finally activated this morning.

I have the same issue on my OP6. I have both installed, but EngineerMode crashes when I try to enable Serial (Full-Port switch is set to On already)

EDIT: Okay, so suddenly PDC worked. I continued with the tutorial until I have to enter the logkit and go to function switch... Which I can't. Dialling *#800# gives me two options, EngineerMode and FactoryMode. Neither of which have a "function switch" option Seems like it was because I downloaded a later version of logkit. Installing an older one gave me function switch.

Followed the rest of the tutorial, aaaand... Didn't work. Phone tells me to turn off airplane mode when trying to call, and when making a call with no signal tells me to connect to service. Even after restart.

I believe this should work on Telus if we can find a way to bring up the wifi calling agreement window, maybe by using the pixel experience ROM? If anyone has an idea to activate the e911 address and accept the agreement for wifi calling on Telus I'm all ears.

I tried with the following link and no luck yet, will restart and go from there. Hope someone can take this and run with it!

[OnePlus 7 Pro Guides, News, & Discussion] archangelz:
So I followed the steps and updated the mbn and it doesn't seem to work for VoWifi even after I activated with the carrier link on my OP7T Pro Mclaran 5G.

I'm getting an "ER05 sim error" though under wifi calling... is my sim maybe really old and needs to be replaced? Or is it the whole I need to wait while this gets activated? I got a text from freedom that says "you have been subscribed to wifi calling" tho. IMS Registation says its "Not Registered" w/ VoLTE and VoWifi Status saying its "Unavailable"

Yes I replaced the efstools file folder with the one from the Pixel 4 downloaded "generic.zip/generic/pixel/NA/freedom/Pixel_VoLTE/mcfg_sw.mbn"

Hello been trying for weeks to get this working on 7pro Android 10 with Koodo.

Which setting did you use in PDC?

I tried all that are NA (Tmo,Sprint, ATT) and Telefonica UK. Never get it to register IMS for VoLTE nor VoWiFi, don't really care about VoWifi

I have tried loading the mbn files for Koodo and Telus from Pix4 through EFS, nada. No errors show up on the PC, and all the mods I enter stick on reboot.

Odd thing is if I put a Bell Sim in my 7pro the VoLTE works within 2 minutes, same if I put my Koodo SIM in a Bell Sams.S8. So I do not believe the SIM card is at fault. Also ripped the Firmware for the S8 for Koodo and Bell, there are no canadian carrier mbn files.

Any suggestions?

Thanks
[OnePlus 7 Pro Guides, News, & Discussion] Sn0wHookr:
For PDC I just followed the OPs instructions, so Commercial-TMO.

Only thing I can suggest is making sure you have VoLTE service on your Koodo account. You can check by logging into self serve, going to "view rate plan", and under Add-ons make sure you have "Koodo VoLTE Access".
[OnePlus 7 Pro Guides, News, & Discussion] pxer:
Thanks for the reply. VoLTE access is active and working, as Koodo SIM VoLTE works in the Bell provisioned Sam S8. I wonder if it has something to do with my OP7pro being rooted and on Beta firmware. Although I doubt it.

I'm having a awful issue.. OP8Pro

I can't get the EfsTools.exe to run.. keeps saying "critical error bad command"

C:\Efs>EfsTools.exe efsInfo
Use serial port 'COM3'
Critical error. Bad command

I also decided to make sure that the program itself is working, and the version flag seems to work fine. None of the other flags work at all though

C:\Efs>EfsTools.exe version
EfsTools 0.11.0.11

writeFile also seems to fail

Tried on a second computer.. Exact same error ( even com3 :D surprising because I use a ton of com devices on this computer ), double checked my command prompt is admistrator, installed the drivers.. I'm Not even sure where to keep going on this.

Any recommendations would be amazing thanks

Did you Turn on Full Port - dialing 801?
[OnePlus 7 Pro Guides, News, & Discussion] TheCookies:
I did, I will try one more time ( reboot and go *#801# again and try ) . The first part where you have to change to commercial-TMO works fine. Its just when trying to install the files with efs.

Tried again, confirmed that "full port" is on.

Same error.

Also just went in and double check PDC.. it can still load all the info from the phone. Turned off "Full Port" PDC can no longer see the com port, and can no longer pull any info from the phone.

Full port seems to be working.. Not sure what else to try.

Thanks

EDIT: Okay i've been thinking.. Is there a way to set it back to factory defaults? Wipe out everything i've done ( not much just the PDC change ) and start fresh?

EDIT2: I reset my phone to factory.. RCS stopped working had to go in with PDC again and set it back to the default settings that way in order for it to pick RCS up..

Oneplus says they will flash my phone or something and "make sure it works" so lets see if they can do it for me.. :shrug: should be such a simple thing for a manufacture to do why is it so damn complicated for the end user.. And why doesn't the manufacturer just.. Do it if end users can figure it out?

Don't know if this will be any help as I have a 7pro, but a guy on oneplus forum, said he got his 8pro working using a similar method found under XDA Asus, but he used EFS tool 1.1 and not 1.2, as 1.2 gave him errors.

I feel your frustration. I do not have an 8pro so I can't really offer any help. All I can say is that there are differences in outcomes between devices even within the same model. My 7pro has VOLTE with every sim carrier I tried except Koodo, which is my carrier, while others with a 7pro have gotten it to work with Koodo using the same mod methods. Now I am thinking maybe it is firmware version, My plan is to cross over to stable and try again to get VOLTE to show up. Odd thing is HD calls are active (HD icon on caller screen). Call quality is good but data drops to 3g/H+, not true VOLTE.
[OnePlus 7 Pro Guides, News, & Discussion] TheCookies:
That is exactly what happens to me. I get the "HD" call but it drops to 3G.. I use a lot of internet while on the phone for work, so having LTE speeds would be very nice.

OP6T connects only to 3G when switched to Overseas TMO profile

Hi,

Thanks for this post. I have been trying to get Volte enabled on my phone, and am glad to know that finally some one made it work.

QQ. The profile reverts to overseas, after i restart the phone. So, i was planning to remove it after activating TMO.But, i just noticed that when i activate TMO, phone immediately switches to 3G(H+) and is no longer able to connect to 4G network. Is this normal?

If i activate TMO, remove overseas and restart the phone, will it connect to 4G again?
[OnePlus 7 Pro Guides, News, & Discussion] nabbasi:
For koodo you can try this. Activate Telefonica_UK_Commercial profile through PDC then you flash using koodo mbn through efstool. This was used in past on oneplus 5 to get Volte on Koodo.
[OnePlus 7 Pro Guides, News, & Discussion] nabbasi:
I don't understand for some phones its acting weird. Can you try network reset then apply these steps.
[OnePlus 7 Pro Guides, News, & Discussion] pxer:
---

First, I do not have a 6T so I am not sure what happens when you make changes. On the 7pro, I did not touch the sw_default and never deleted the overseas profiles. I never had issues connecting to 4g no matter what profile I activated. What I did notice is sometimes my APN would get confused especially when loading different mbn files thru EFS. But selecting the right APN manually would always reestablish 4g. Based on what I have read, you should not delete the overseas profile, only deactivate. I am rooted, and profile changes always stick after reboot. I have read in the other VOLTE threads, that root is required, yet others say it is not required to make it stick. Don't know what to tell you for the 6T. Have you read the 1+ forums, there is plenty of information on the 6T.

Thanks for the suggestion, trust me I tried that. Tried Koodo mbn from Pixel3 (which is labelled VOLTE), Pixel 4, Mi, S10 and each different profiles (TMO, TeleUK, Sprint, ATT, IndiaVoda, GermVodo, Finland, LabVolte etc etc) each time no VOLTE. I even tried Telus MBNs, nada. I have even reset the MODEM and EFS partitions from my twrp backup so it could be a fresh database, No Joy.

Today I will try to cross over to stable 10.3.4 as others have reported success on that firmware.
[OnePlus 7 Pro Guides, News, & Discussion] archangelz:
So I got my replacement phone and and tried the steps again and I noticed in the PDC Tool after I put the pixel config in it no longer is on "Commericial-TMO", it's switched to "VOLTE_PTCRB" active on "Sub0". Is this right for Freedom?

For my Oneplus 7T Pro 5G I only have one sim slot, but my sim is showing up on sub1 and not sub0, but only sub0 is activated in PDC. I had followed the steps to switch to "Commercial-TMO" before using the efstool.

I still have no IMS Registration and "UT Interface" shows up as unavailable, but then again I've only waited for half a day.
[OnePlus 7 Pro Guides, News, & Discussion] pxer:
Activation will be withing 15 minutes at most for VOLTE, but UT interface needs to be available.

So I have a few questions:

You are using a 7T pro?

In PDC - by device WWAN adapter show #2, do you have some other device plugged in to the PC

- your description lists service providers (i.e. Rogers) that don't show on my list for 7pro. did you change something on your NV?

Best of my knowledge, you need Commerical TMO or Telefonica UK
[OnePlus 7 Pro Guides, News, & Discussion] archangelz:
I'm on a 7T Pro 5G HD1925 Mclaren... I switched to "Commercial-TMO" using PDA tools and rebooted a few hours ago and am still not registered. I have not changed anything in my NV outside of stock. Still getting a sim error for wifi calling despite having registered for it.
[OnePlus 7 Pro Guides, News, & Discussion] pxer:
Well step one complete, showing UT availalable

Does VOLTE work?

Did you load the MBN for Freedom through EFS from pixel 4

Since you already registered online, I have heard it may take some time to get setup, I assume you did not get the text (sms) when you ticked WiFi calling

Did you, with WiFi on (exempt) try toggling airplane mode to kill voice connection

I don't have VoWiFi, Koodo does not offer, but I have read about others doing the above to trigger the hand off.

I am having a heck of time getting VOLTE working, curious to know how you got Rogers to show up in the PDC list

BTW nice phone
[OnePlus 7 Pro Guides, News, & Discussion] archangelz:
Thanks, I probably should have just got the standard 7T Pro. The 7T Pro 5G is carrier updated w/ no global option but I didn't think that far ahead when I bought it. I got the VoWifi registration text message a month ago when I registered right after I bought the phone but it hadn't shipped yet.

VoLTE and VoWifi don't work as far as I can tell because of the lack of IMS registration . I downloaded the Pixel 4 MBN (generic.zip) from the second post of this thread. https://xdaforums.com/pixel-4/help/mbn-files-pixel-4-request-t4050247

Oxygen OS 11 release - unable to enter Full Port Switch

Hello everyone, first of all thanks to this community - I am confirming that the method works on OP 8Pro Oxygen OS 10 (Android 10). Both Volte and wifi calling works great (used EfsTools 1.1 to copy mbn files from pixel 4).

Today I have upgraded to Oxygen OS 11 (Release, not beta) because I needed to activate a second SIM card slot.

After upgrade I immediately lost VoLTE and WiFi Calling capabilities, IMS is no longer registered and phone stopped connecting to Freedom Band 13.

I assume upgrade "resets" radio and VoLTE / mbns (forgive me for being technically illiterate) ...

So far nothing worked to flash mbn back nor use PDC tool. Here is what I tried.

1. *801# --> Full-port switch. Launch PDC tool. Result: any selection from the drop down, no COM port appears in device manager.

2. *801# --> Rndis, diag switch --> COM port appears but EfsTools 1.1 or EfsTools 1.2 return "Critical error. Bad command".

Also wired behaviour, USB tethering turns on when I turn on "Rndis, diag switch" , that did not happen on Oxygen OS 10.

Also andrew2401, please explain what is "select radial", I did not see that in the menu when going to *#801# .

Has anyone been able to make it work on Android 11 ?

Thanks in advance.

That is inspiring to hear you got it working and thank you for the link for the VoWifi,.

If I may ask, did you follow the OP with Tmob in PDC and Pix4 Koodo mbn with EFS tools?

If so, for EFS did you use EFS tools 1.1 or 1,2 and on the phone Port Switch or Rdnis?

I still can't get my 7pro to IMS register, when I activate Tmob profile in PDS, EFS manger sees the phone with a Tmob profile, when I flash the Koodo mbn, it shows as Koodo,. So my amateur assessment is that one process overrides the other. I have even tried the Koodo Volte labelled Pix4a mbn (be it for android 11) and still nada.
