I'm HTCMAGE.

Last year, Xperia 1II.

How to activate VoLTE.

After the guide version,

VOLTE Success, Activation without Firmware Replacement (Sony Mobile withdrawal area)

Hello Xperia users! In the meantime, I finally solved the VOLTE problem! I approached Qualcomm's diagnostic port-active-efsExplorer and solved the problem by inserting a VOLTE profile from my carrier :) Sorry, this is Korea and I am Korean...

forum.xda-developers.com

5II and...

Xperia's 1III/5III products.

Activating VoLTE and...

"Root".

I'll share how to turn it off.



I am not good at English.

I use the translator.

Please understand.

Later, to unlock.



Maejiseukeu manager app.

Patch. magiskFiles img



While connected to your computer with a usb



You can use the instructions below at least adb.

adb reboot bootloader && fastboot flash boot "magisk.img" && fastboot reboot

Then, you can install it.



It's going to rebooted.



This is the restart screen. It's connected to USB.



Always allow debugging when enabled.

Connect to Wi-Fi and do not log in.



Please move on quickly.

Turn off the internet quickly (Mobile data X)

Save the magisk manager app on your computer.



Then go to Xperia and install it.

github.com/topjohnwu/Magisk/releases/tag/v23.0

Please make sure the Internet is turned off.



I'll carry it out. Magisk Manager in the upper right corner.



Cogwheel - Setting page - Middle.

Activate "Hide".

When it's done, we'll start the VoLTE patch.



At least ADB.



Adb shell.



Enter and enter.



su



If you type it in,





In the same window as the picture below,



If you allow it,

The shape of the dollar...

It changes to #.

setprop persist.usb.eng 1

Enter and enter.

It's from My Computer Properties Device Manager.

There are several floating yellow exclamation marks.

Drive manually.

Please hold it.
Among the yellow exclamation points,

We don't know which part is connected.

Please select a few targets and update them manually.

Update Driver - Browse to My Computer

Directly select the list available on your computer.

Port-QUALCOM 9081 choice.

Starting with the ELS Explorer selection LAHA (based on 1 III).

This is something that can go in. If you connect...


Please copy and paste the EBS file.

(Use the mouse to pull it in and put it in twice.)

I'll make a folder that doesn't exist.

Put it in twice.

Policyman folder delete the existing one.

You can put it in and the NV at the top...
Likewise, place it at the top.



Close the window when done.

adb shell su -c setprop persist.dbg.volte_avail_ovr 1


adb shell su -c setprop persist.dbg.vt_avail_ovr 1



And then "adb reboot".



If you type Enter, we'll reboot you.

On the basic Soonjung phone app,


Check IMS status in *#*#4636#*

If it's available, it's good.

Wi-Fi or data on.


Log in various ways. Google, Sony accounts,


Update the Play Store and...

Various basic apps (Netflix)


Update everything.


And information on the bottom of the Play Store,

It should say play protection certification.

If you run the magisk manager app,


If you check out the following,


I reboot on my own.

Reboot and run the manager app again.


Please press "Remove the Magisk".

Completely removed.
Then I'll start deleting and reboot on my own.

Delete completed.

Finished.



It's easy to use.



Netflix is also on PlayStore.

It'll be updated normally.

root
If you maintain the route,

I change my font or record on the phone.

When you do the whole gesture, remove the bottom white stick.

That's one of the advantages.



You can choose Xperia.

The users can choose.

In the old guide version,
My English skills that I'm not good at...
This person translated it.
Please keep in mind.

The EBS file (VoLTE file) is...
It's in Sony firmware.
In the country you're using,
All the mobile carrier files are in here.
You can use that.

It's in the policy man folder.
You must modify the XML file!

In the area that was withdrawn,
I don't have a mobile carrier band code.
Make sure to change it to a notepad.

If you change the XML file,
VoLTE, of course.
5G works normally, too.

My poor English skills...
Someone wise.
Please deliver it.
We wish.

Be happy always.

How can I get the efs file？

 

[htcmage]

/system/vendor/firmware_mnt/image/modem_pr/mcfg/configs/mcfg_sw/generic
It's in the firmware or on the device

 

[Frederick888]

So you can either unlock BL & root to have VoLTE, VoWiFi, etc; or keep everything untouched to have Widewine DRM (Netflix HD etc), full camera filter support, etc?

There is just no middle ground, is there :-/

GOOD JOP

How about WiFi calling?

That's annoying that WiFi calling is disabled.

I hope Sony fix volte issues globally for the upcoming Xperia 1 IV. All other manufacturers such as Xiaomi don't have this issue even if it's a grey import. I don't see why Sony can't fix the problem

I think nothing will change.

I think nothing will change.

I will basically stop buying a Sony phone as simple as that.

Battery consumption is higher with 5G.
What benefits do you get with 5G besides speed?

I am happy with 4G as it is more than enough for my general usage.

What I want Sony to basically fix is volte and WiFi calling as that is a deal breaker considering 3G network will be phased out.

If Sony don't fix volte issue then certain countries will not be able to buy the upcoming Xperia phones as it will no longer be able to make calls.

You can enable VoLTE by flashing SEA firmware without unlocking bootloader.

Yes I have volte working by flashing SEA firmware. Working in Australia on Vodafone only for the Xperia 1 II.

However I haven't heard anyone getting it to work on the current generation Xperia 1 III so that puts further Doubt on the upcoming Xperia 1 IV which would be enough to keep me away and look elsewhere instead. It's not possible to make calls it volte doesn't work and 3G network is shut down

It's working with me.

 

[Hazzay88]

It's working with me.

That's good to hear.

Which country and carrier are you with?
Also did you get it to work after flashing it with SEA firmware to get it to work
