If you have non-working VoLTE/VoWiFi on your current custom ROM here is how to solve it.

Requirements: Rooted phone

Qualcomm PDC Tool and Drivers (attached) (QPST)

PC + modem profiles (attached) + adb


I’m not responsible for any bricks/wipes/deaths/missing things etc. !!!
THIS GUIDE WAS TESTED ONLY ON POCO F3, TRY ON YOUR OWN RISK ON OTHER XIAOMI DEVICES


0. BACKUP YOUR EFS AND MODEM FILES AND REMEMBER WHAT WAS DEFAULT IN PDC

1. Find a correct profile for your carrier if you can and make sure your VoLTE/VoWiFi is enabled via dialer codes (*#*#86583#*#* for VoLTE and *#*#869434#*#* for WiFi, there should be a notification ‘VoLTE/VoWiFi carrier check disabled’ but not all ROMs have that)

2. Install QPST, install drivers (you may need to disable secure boot or some sh*t I dunno)

3. Connect your phone via USB with USB debugging enabled

4. Run adb and use these commands:
adb shell
su
setprop sys.usb.config diag,serial_cdev,rmnet,adb
(this last command may reboot your phone on some custom ROMs, in that case switch ROM or ask your dev to fix it or try it on the phone in Termux and then connect USB)

5. Open PDC (search via start)

6. Select your device in the dropdown menu (Qualcomm HS-USB WWAN Adapter 9091)

7. Select load and select a correct profile for your carrier (for example Profiles\EU\Vodafone\VoLTE\CZ\mcfg_sw.bin for Vodafone Czech)

8. Find your profile in the main window of PDC, right click on it a set for Sub 0 and 1

9. Select the profile you previously used for Sub 0 and 1 and select activate

It should look like this:

10. Wait for it to hopefully load signal and work, try to reboot to see if the profile persists

11. Check VoLTE and VoWiFi on your phone, if it works congratulations, if not you may need to try other profiles and see if they persist after reboots

After reflashing ROM/firmware you may need to redo the whole procedure

These profiles were extracted from modem.img from POCO F3 firmware 13.0.7.0 SKHEUXM, not sure how it works with other global/indian/chinese versions, all profiles available are here:

yeah it dont work in W11.

QMI connection not ready please use usb driver version 1.00.32
You could try this method but I have never tested it as it looks more complicated that this one, do it at your own risk

haha yes so complicated. i tried but dont understand a thing. there are few meathods with EFS explore . but complected. and as i remember messing up with modem is not a good idea
 
Thanks for this guide, it worked for me with windows 11. However when I tried to use this guide on my F2 pro it didn.t work, same driver problem as for the rest of people in this thread who is on w 11. Little weird. Did anyone on w 10 try multiple times? Thinking of downgrading to w 10 if thats the case. I like to change roms quite often 😀
 
After many hours of testing both w10, w11, fw, roms I finally got my F2 pro working with volte. It seems that it has nothing to do with windows or drivers but encryption on the phone. Almost all roms on F2 pro are decrypted therefor the hassle. When I tried the latest Spark who has encryption it connected to the modem. After I got volte going I could flash the same fw and and the rom that I wanted which is decrypted and volte was still going.

It sticks after clean flashing another fw too.

    If you have non-working VoLTE/VoWiFi on your current custom ROM here is how to solve it.

    Requirements: Rooted phone

    Qualcomm PDC Tool and Drivers (attached) (QPST)

    PC + modem profiles (attached) + adb


    I’m not responsible for any bricks/wipes/deaths/missing things etc. !!!
    THIS GUIDE WAS TESTED ONLY ON POCO F3, TRY ON YOUR OWN RISK ON OTHER XIAOMI DEVICES


    0. BACKUP YOUR EFS AND MODEM FILES AND REMEMBER WHAT WAS DEFAULT IN PDC

    After many hours of testing both w10, w11, fw, roms I finally got my F2 pro working with volte. It seems that it has nothing to do with windows or drivers but encryption on the phone. Almost all roms on F2 pro are decrypted therefor the hassle. When I tried the latest Spark who has encryption it connected to the modem. After I got volte going I could flash the same fw and and the rom that I wanted which is decrypted and volte was still going.

    It sticks after clean flashing another fw too.
