Interesting, thanks. will learn it and report if I succeed (or if I brick my phone...)
 
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.
However, I will write down the method in English.

Unlike previous 1&5, Qualcomm's diagnostic port cannot be opened.
opening command
I don't even know. I don't think so.
So it's a little different from before.
I tried to force it open.

debugging connection
Open the Command Proposal window.
adb shell input
su input
Do you want to allow shell on your phone?
prompt acceptance of permission
Then the $ shape changes to #.
Now
setprop persist.usb.eng 1
Copy paste entry. Please enter
And you're gonna be out there during tethering.

In My Computer Item
View Device Manager.
Please turn debugging back on.

Of course, no access.
If you turn on debugging again,
I've already set it up, so it looks like that.
Among them, there is a product model named XQ-AT52.
There are four yellow exclamation points in total.

Manually update driver Press [port] to list the manufacturers
It's called Qualcomm hs-usb-diagh and 9091. with this
I need a manual update. gogo

Now run the EFS Express.
Press 0 on the ROW and OK.
(ROW or SF_Default)

Oh, it takes a long time. I thought it stopped.
It opens if you stay still. LOL
It's open. How nice to see you here!
I am the Korean telecommunication company EFS file extracted from xperia1.
I used it. If you need VOLTE,
XPERIA1 (Modem).Extract from SIN file
I will use the Korean communication file.
Just drag it and put it in a folder.
v check and Yes
There'll be folders that don't exist while you're pulling them in.
Then make it and put the file in.
In the folder where you can view this red file,
Drag and drop the file twice.

The reason is that once you do it, you just go in.
The red file is not updated.

That's how the numbers at the back change when you renew.
So make sure to put it in twice.


Files beginning with NV do not have folders.
Put it on top.

It's over now!

It was such a hard time for me!
I was sad because I couldn't get help.
With 5G mobile phones in 2020,
It was terrible to be on the 3G phone.
If there's someone like me,
This information will help you a lot.

Does this method requires rooting?

Sony Xperia 1 II
Guys can we add extra 5G bands on Xperia?

Because same CPU on OnePlus 8 Pro have more bands which is not listed on Xperia. Can we copy the mbn file from OnePlus to Xperia and make it work?

    how to

    Even with the great contributors' information, I think there are a few areas where I struggle.

    For additional information, I will post my success stories.
    I'm posting them in machine translation. Please forgive me if it's hard to read.

    STEP 1: Implement the Tools You Need
    Please install the following tools.
    QPST(QPST_2.7.460)
    Qualcomm-hs-usb-diagnostics-9091-952454(DIAG driver)
    Flashtool (and XperiaFirm)
    newflasher(INSTALL is unnecessary, but please get it.)
    *All of the above were available on the internet as of 8/15.

    STEP2: Get a "modem" that supports VoLTE.
     As a prerequisite (regardless of the DualSim/SinglSim model)
      For countries that want to use VoLTE, SONY is offering
      Official firmware is required.
      In my example.
      Purchased model: XQ-AT52 (for Hong Kong)
      The country where you want to use it: Japan -> SO-51A is available.
      (The difference in the number of slots in the SIM doesn't affect it. )
      This is the case.
      If the firmware to run VoLTE does not exist in the country where you want to use it
      This method does not work.

      The annotations are long, but here are the steps.
      Use XperiFirm, provided by SONY in the country where you want to use VoLTE.
       Download the firmware.
      
    STEP3: Use the newflasher to write the firmware from STEP2 to your Xperia 1 ii.
       In this case, if you want to burn into a model with a different number of SIM slots
       Example: Writing SO-51A firmware to XQ-AT52
       →The SIM will not be recognized, but it is temporary.

    STEP4: Use EFS Explorer to get the necessary files.
      Follow the steps of the great htcmage and have your Xperia 1 ii recognized by EFS Explorer.
      4-1: Install the QPST.
    4-2:Install Magisk on your Xperia 1 ii.
        Therefore, it is mandatory to unlock the bootloader.
      4-3:Execute the commands at the command prompt as follows.
        adb shell
    su
    setprop persist.usb.eng 1
    Magisk's permission is now required to get SuperUser privileges in su.
         Note: From the Magisk menu, go to "# SuperUser" and click on
         You can allow.
    4-4: The debug mode is disconnected, so you need to re-enable it.
    4-5: If you have installed the qualcomm-hs-usb-diagnostics-9091-952454 (DIAG driver), you can use
        It is recognized by EFS Explorer.
    4-6: On the Phone Selectio screen, Banner selects the ROW port.
    STEP 5: Back up the files required for VoLTE activation.
    Before following the steps below, you must have the SIM of the line/carrier you want to enable VoLTE on.
        Please plug in.

       I have backed up the following folders.
       There may be some things you don't need, but at least it works.
       Data_Profiles
    efsprofiles
    Ims.
    nv/item_files/datamodem
    nv/item_files/ims
    nv/item_files/mcfg
    nv/item_files/modem

    STEP6: Write the firmware you want to use, and copy the file from STEP5 to
       Override.

    Follow steps 3 to 4 of STEP 3 to 4 to get the firmware you want to use.
       Write & make EFS Explorer recognize it. (Don't remove the SIM.)
       Then, overwrite it with the files backed up in STEP 5.

    You should probably now have VoLTE available.

    Thanks to the person who walked me through the Magisk installation process, and to the great htcmage.
    Also, I pray that others wandering in the same sea of information will be saved.

    Hello, you are so cool:) Thank you so much for organizing the guide. I hope it helps many xperia 1 II users ah! I opened the volte-related menu without changing the firmware using the magical module. The reason is that the buildprop cannot be modified for this xperia1 II:eek:

    Hi! We have the same model, where did you sim unlocked your device?
    I used a software called S1 Unlock Tool. You need to buy a credit from this website: https://networkunlocking.com/shop/sony-xperia-cable-unlock-0-counter-supported/. There is also a link to download the software. Along with unlocking your phone it will also grant you access to unlock your bootloader if you wish to do so. I did this and tried to root my phone but I wasn't successful, it just soft bricked my phone and was stuck in a boot loop. I had to use Xperia Companion to restore my phone. Maybe you can't root the Japanese variants, I'm not sure. I saw on here on another forum that you can root the Xperia 1 II.
