Hi, I am using pixel experience 13 with my Xiaomi 11T (Mediatek Dimensity 1200) I live problem with engineer mode. it is not possible to enter it. I tried codes and also applications from play store but I couldn't be successful. I think it is rom related. Cam you help me?
[OnePlus 7 Pro Guides, News, & Discussion] h325190:
13. If u have an issue with VoLTE (may go in default setting after reboot - DC Commercial), then do next after step 8 : Click on “Oversea-Commercial_DS” again and below click on the “Remove” button.

Is it safe to remove the default profile? Can it cause any issues later? Volte disappears after I restart my device.

thank you

Hello everyone

i have oneplus 7 pro OOS 12.1

i want somehow to enable volte switches on the settings without root ... i have access to engineering mode (which i could use PDC,Efs Explorer)

but i dont know how to make it so the switches to stay visible on the settings

i tried also with another sim which shows se volte/vowifi swithces on the settings but when i put back my sim the switches dissapear again

is there a way somehow when i put the sim card wich makes the switches visible to the settings and somehow with pdc or efs explorer to make it somehow the swithces to stay visible in the setting when i put back my other sim

thank you

I'm excited to find this guide and hope that it will help me get my vowifi and volte working.

Just hope if anyone could confirm if this is working even with oxygen 12? I have op7 pro updated to os12. I did previously ran logit n turned on WiFi n volte which shows but doesn't work as I didn't take further steps to do the pdc and efs thing as I wasn't too sure how it works.

Do I need to root my device if I'm too proceed? I read in many threads that this is not working on oxygen 12?

Would appreciate some help as I would like to get it working. I know the mdb file I need to work on my network.

Thanks a million.
[OnePlus 7 Pro Guides, News, & Discussion] newr:
How about on os12? Does root require? Can someone also clarify, I understand the logit.apk doesn't when on Android 12 but the tutorial doesn't say anything about how to turn on volte and vowifi option. I dud turn it on b4 on 11 but now with 12 cannot install the apk or get into the mode with *#8000 or 8001
[OnePlus 7 Pro Guides, News, & Discussion] jimmy123322:
Yes, root is still needed!
[OnePlus 7 Pro Guides, News, & Discussion] newr:
Thanks for the confirmation. Could I then turn on volte / vowifi after its rooted? I don't see any steps about turning on that in the guide for Android 11/12. Lastly, could any one suggest any guide to root this when on oxygen 12, ive found some guides but they were for previous version, not sure if it's same with the newest OS. Haven't rooted one for almost 10 years, so kinda out of practice.

Thx again
[OnePlus 7 Pro Guides, News, & Discussion] jimmy123322:
You can use the same method (A12.1/A13 custom ROM) for OOS 12. It fully working.
[OnePlus 7 Pro Guides, News, & Discussion] newr:
In the guide, there's no step to turn on engineering mode or the volte with logit.apk. Is this not done for the os12 method?
[OnePlus 7 Pro Guides, News, & Discussion] jimmy123322:
Old methods from OOS10/11 won't work on OOS12. U need to use new one.

Hi

I have debloat my stock os and able to use Volte but wifi calling isn't working. Before debloating it was working fine.

This what I get on IMS registration - screenshot.

How can i fix it?

im using OP7 OOS 10.3.8 (A10) - Airtel India (Service Carrier)
[OnePlus 7 Pro Guides, News, & Discussion] newr:
I managed to get it working after rooting and went thru the efstool and pcs method. I have unrooted my phone again but I noticed the square app I use is not letting me do a secure session with the Bluetooth reader. I assume it's related to root or the imei issue. Says device not supported and to use different device or factory reset.

Just wondering, will I lose the volte /vowifu function if I do factory reset? I'm running most current oxygen right now
[OnePlus 7 Pro Guides, News, & Discussion] jimmy123322:
Make sure that you enabled Wi-Fi Calling in settings. Also don't forget to check that VoWIFI feature enabled on carrier-side. Note, that not all operators support VoWIFI calling feature.

If you do a factory reset, nothing will happen with modem.img which contains data about your SIM carrier. But on OOS 12 you may need to activate VoLTE and VoWIFI again in system, not through PDC or EFS. On many custom ROMs VoLTE/VoWIFI support enabled by default, even after factory reset (example - crDroid).
[OnePlus 7 Pro Guides, News, & Discussion] varunpilankar:
My carrier supports Vowifi, I was using it before on my OP7. But after I debloat OP7 (removed OPlogkit and engineering mode) and it stopped working.

I tried reinstalling both the apps but still not luck. Is there another method to fix it?
[OnePlus 7 Pro Guides, News, & Discussion] jimmy123322:
Just re-enable or re-install this apps through adb.
[OnePlus 7 Pro Guides, News, & Discussion] varunpilankar:
Already tried that.. Still no effect
[OnePlus 7 Pro Guides, News, & Discussion] newr:
I'm on oxygen 11 now, so factory reset won't cause it to lose the volte / vowifi then.

Has anyone managed to get VoWifi working on Verizon?
[OnePlus 7 Pro Guides, News, & Discussion] eXalife:
Thank you for the guide but many people have been experiencing driver problems for a long time and I think I understand what is causing it. It appears to be caused by the USB Gadget Tool modes. Without those modes the device can be selected from PDC.

@Alexxxx1 thank you for the video but I wish the PDC screen could be more readable. Nevertheless, I finally managed to work VoLTE on a13/Linageos 20/7 Pro without the driver issue. In your video you didn't set modes from the USB Gadget Tool and the culprit to driver issue is these modes. When I set these flags the phone doesn't show in PDC and in device manager listed as multiple unknown devices like this:

I experimented with the modes and I think especially diag.diag.mdm, gsi.rmnet and qdss.qdss.mdm ones are the problematic ones. I couldn't try much because changing these modes while connecting to USB causes a freeze on a black screen and requires a volume up+power boot to recover. Without setting any modes the device can be selected from PDC.

Also my PDC list differentiates from the OP's tutorial. I'm uncertain what is causing these differences.

There was no Oversea-Commercial_DS for me instead Common-Commercial and Free-VoLTE had Sub0 and Sub1 so I disabled these two:

Also, I couldn't find India_Volte_Vodafone. Someone on the 4pda forum called IN_VDF as Vodafone India. So I activated that one for Sub0-1. I am not sure it is related to India or Indonesia but for my Turkish Turk Telekom operator IN_VDF works.

I couldn't understand the purpose of these gadget tool mods. They were completely unnecessary for my LineageOS custom ROM. Considering that the OP couldn't relate to the driver issue all this time, it seems that they don't have a clear understanding either. I hope the guide can be updated to indicate that this step can be optional.

Hello everyone.

I activated the volte and the vowifi on my oneplus 8 pro, on my two SIMs, with the manipulations * # 800 # / * # 801 # ....

And the operations with the PDC software by deleting the oversea commercial profile, etc.

Everything works perfectly fine ... Except for each update of Oos.

Indeed, after the update, the Sub1 profile is deactivated and the commercial oversea profile reappears. I therefore lose the volte and vowifi on my sim 1.

I have to redo the manipulation with the PDC software and a computer after each update. Which is painful.

My question is, is it possible to make a backup without Root, of the parameters of the onepluslogkit software for example, to avoid losing the volte and vowifi on certain SIMs, following an update?

To avoid using a PC and PDC software?

Thank you in advance for your replies

I ran through the steps in OP and used the Telefonica_UK_Commercial profile.

what I did next was from the freedom volte thread

Next step:

7. Open CMD as Administrator on the PC, navigate to the folder where you extract the files (eg. cd c:/Efs)

Now execute the following commands:

after running EfsTools.exe efsInfo you should get a similar message to this:

If you get the above, proceed, otherwise you need to ensure you are set to serial or full-port switch in engineer/factory mode.

The CMD will process the file. Restart. My VoLTE came on immediately afterwards.

[OnePlus 7 Pro Guides, News, & Discussion] Guido83:
just plug your phone to a computer where you open a terminal and type:

adb devices

make sure your device is being listed

adb shell

su

grant super user rights for ADB if not already done.

setprop sys.usb.config diag,serial_cdev,rmnet,adb

check in device manager whether your phone is listet in com ports as debug device. otherwise use proper drivers

then you can use PDC
