All Xperia phones dont have profile for my country. I dont have needed xmls to update Qpst.

I managed to run PDC. I tried to load mbn, but it doesnt save. I installed selinux module. Any idea?

Hi @jattal ,
How did you manage to get PDC working? I tried following

https://xdaforums.com/t/guide-windo...re-and-gsi-rom-flashing-without-twrp.4344373/

But couldn't get su command to work. Instead of giving an error that I don't have su access, it just left a blinking cursor. So I haven't been able to run

setprop persist.usb.eng 1

from https://xdaforums.com/t/volte-succe...mobile-withdrawal-area.4144701/#post-83277123

I'm also trying to update modem settings. I was going to try with the pixel 4 mbn.

 

[jattal]

After Magisk
Install latest Qualcomm drivers
Adb reboot ftm
Shell and su
setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb
Pdc should recognize phone

Hi Jattal,
Thanks for the reply.
I'm still stuck at getting su working. I've got questions about that posted in another thread.
I'd really like to hear if you get your volte/vowifi working for a country without a profile.
Which mbd files were you going to try to use?

 

[jattal]

Make sure Magisk is installed, proper adb drivers installed, debug is enabled.
Once you su, grant it in the phone screen.

 

[jattal]

I couldn't activate volte, the mbn file wasnt being saved when i loaded it. I activated row commercial and got 5g working.

I'm tempted to get a Xperia 1 iii or Xperia 5 iii if VoLTE works.
I'm in Australia, does anyone managed to get VoLTE working following this method?

I can't comment on the Xperia 1 Mk3 or Xperia 5 Mk3 but by flashing SEA firmware volte works on Vodafone Australia. I don't know anyone who has had success with the Xperia Mk3.

I would wait for the Xperia 1 IV at this point of time but this means minimum June release. However it will be announced soon

I have it working but with a much simpler method: flashing SEA firmware. Works on an Optus MVNO for me, reported to work well with Telstra as well

Yes MVNO works.

However with Vodafone it works which I'm fine with. However wifi calling doesn't work

So which device are you using?

 

[Hazzay88]

Xperia 1 II.

I don't know anyone having it working on Mk3 phones in Australia

With the Xperia 1 II it was straight forward firmware flash for volte to work

 

[johndaniel]

don't know if this will help anyone much, but i started this route to enable 5g and volte. I have xperia 1 iii and did exactly how it was mentioned in this post till adding efs files , but to no luck i never found the xml or efs files for the country iam at . extracted the modem file got the mbn files, yet couldn't implement into the phone.
even flashed sea firmware and HK firmware , still no volte or 5g. so then bit of digging understood carrier config xml can be added to the policyman folder under efs explorer and most of the MEA region should get 5G.
I was able to get 5g from the 3 carriers in kuwait. fast switching between 5g-4g-3g-2g. so no issues with calls.
So just add this file carrier_policy xml file to policy man folder under efs explorer and restart phone to get 5g in MEA/Africa/Asia region. Till now i never got the VOLTE working in kuwait.

Also FYI my Xperia 1 iii is us variant . so cross flashing with SEA or Asian firmware ended up in no radio/ sim function. The oem files under the firmware are creating this issue. so unless its same model number different region can be flashed.
