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

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.

After Magisk

Install latest Qualcomm drivers

[Sony Xperia 1 III] mavicanuck:
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?
[Sony Xperia 1 III] jattal:
Make sure Magisk is installed, proper adb drivers installed, debug is enabled.

Once you su, grant it in the phone screen.
[Sony Xperia 1 III] jattal:
I couldn't activate volte, the mbn file wasnt being saved when i loaded it. I activated row commercial and got 5g working.
[Sony Xperia 1 III] daufoo:
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?
[Sony Xperia 1 III] Hazzay88:
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
[Sony Xperia 1 III] treff89:
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
[Sony Xperia 1 III] Hazzay88:
Yes MVNO works.

However with Vodafone it works which I'm fine with. However wifi calling doesn't work
[Sony Xperia 1 III] daufoo:
So which device are you using?
[Sony Xperia 1 III] 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
[Sony Xperia 1 III] 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.
[Sony Xperia 1 III] johndaniel:
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.
[Sony Xperia 1 III] htcmage:
adb shell su -c setprop persist.dbg.volte_avail_ovr 1

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

If you have changed MBN or EFS to your Kuwaiti carrier, please make a VoLTE menu with the above command.
[Sony Xperia 1 III] johndaniel:
I did flash the zip ,to enable the button but still , the volte ims is not Registered or volte doesnt show. I only changed the carrier policy xml file under policy-man folder. Since i never got any other efs files for volte. I do have a mbn file for the carrier but dont know how i can load that.

What all i did is :

1)tried to flash BC62 to BC

72 Sea firmware using newflasher, ended up with sim not able to activate.

2)Flashed only the modem from BC72 on BC62 using new flash still no volte ,but sim works.

3)Imported a carrier xml i edited from MBN file using notepad++ , and placed that in policyman folder got 5g but still no volte.

4) flashed the zip for volte button from your post and still no volte .

Sim has volte enabled , works on Samsung.
[Sony Xperia 1 III] johndaniel:
How can i extract the efs files from a MBN file or ,can i load that MBN in phone ? And which folder i need to load efs file for volte?
[Sony Xperia 1 III] htcmage:
run root explorer

Mobile phone permission (no indication related to approval, please press the magicsk app)

As you watch the video above,

There is an oem.txt text file, the Kuwait MBN entry path is

It's missing, so you need to specify the path

Kuwait carrier files from PDC

can load

youtu be/t-KLgbLxZME

This is a video I uploaded for a guide at the Sony Korea User Association. Please refer (text file path)
[Sony Xperia 1 III] htcmage:
you need to edit the file by putting the path into the OEM_SW text file to load MBN
[Sony Xperia 1 III] htcmage:
The path you want is in the MBN_SW text file.
[Sony Xperia 1 III] johndaniel:
thank you so much, will try this out and report.
[Sony Xperia 1 III] htcmage:
yes after editing the oem text file of the carrier file you are using, load it from the PDC and then activate it. Please repeat the same process twice. Rebooting the phone can solve it. Once active, it is fixed.
[Sony Xperia 1 III] johndaniel:
PDC does not show the device.
[Sony Xperia 1 III] htcmage:

[Sony Xperia 1 III] htcmage:
Do you have teamviewer? I'm worried that there will be a lot of time difference from Korea, but if it's too difficult, please ask
[Sony Xperia 1 III] johndaniel:
Now volte, wifi calling and 5g works on xperia 1 iii and xperia 5 ii . Can confirm it should be working for even countries without MBN in firmware from sony and also can be reverted to non rooted and locked bootloader. Thanks a lot to htcmage, with his help this was done.
[Sony Xperia 1 III] htcmage:
Congratulations :)
[Sony Xperia 1 III] LaceeWearsPrada:
How? How can I do it without root and unlocking? I really need VoLTE. Idk why it isn't there while my carrier supports it. Telenor Hungary (from march it's Yettel HU), XQ-BC52. If it's an easier way, I'd flash the SEA firmware. Will it work with this version of 1 III?
[Sony Xperia 1 III] johndaniel:
I dont know if flashing sea firmware will work , since i had xperia 1 iii bc62 and xperia 5 ii bc52, i flashed both phones with their respective sea firmware and both i lost the sim capabilities literally. I took the long route, as htcmage explained in this post. With the extra steps as trying to find a phone based on the same snapdragon chipset available in the country and extracting the modem from that and with help of htcmage converting the mbn of the country iam at to EFS files.

Rest was just placing them in the corresponding folder using efs explorer.

To return back to stock then removed the root from magisk by uninstall and then flashed the original boot img to make double sure and at the end relocking bootloader. Since post android 12 there was no ota , iam not sure that works but i did get xperia apps to update from sony update center. And yes factory reset still did keep the efs files i uploaded to it same.
[Sony Xperia 1 III] mj673687:
Hi,

Am from India and I bought Xperia 5III from au Japan(sim unlocked version modern num SOG05). Am able to get the network(sim detects jio carrier) and enable 4g data(internet service), but not able to call via VoLte. Tried following the steps from the thread but did not succeed. got stuck at step 2 itself..

when I flash the "magisk.img" am getting the below error.

Would be helpful if someone guides me with this...

Thanks in Advance!!!
[Sony Xperia 1 III] johndaniel:

[Sony Xperia 1 III] johndaniel:
did u unlock bootloader
[Sony Xperia 1 III] mj673687:
Not able to unlock bootloader. My bootloader status for un lock is No
[Sony Xperia 1 III] johndaniel:
How to unlock bootloader - Open Devices - Sony Developer World

developer.sony.com

its easy , make sure cable and drivers are installed properly, also if one code doesn't work, press generate from the sony website to generate another unlock code.
[Sony Xperia 1 III] mj673687:
By the steps from website

In your device, open the dialer and enter *#*#7378423#*#* to access the service menu.

Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

my bootLoader status says no. In spite of that tried unlocking with adb, but adb also failed giving error as permission denied
[Sony Xperia 1 III] johndaniel:
enable oem unlock from developer mode in phone, check out the forum for unlocking and rooting xperia 1 iii,follow each step, its a easy process.
[Sony Xperia 1 III] johndaniel:
To enable developer mode tap build version under about phone 3 to 5 times.
[Sony Xperia 1 III] mj673687:
yes i have enabled usb debug and enable oem bootloader unlock, the above error was with these steps enabled
[Sony Xperia 1 III] johndaniel:
try s1 unlock tool, reports from reddit and xda says it works for xperia 5 iii, remember to just unlock bootloader nothing else, make a backup of all files, and S/N, imei etc
[Sony Xperia 1 III] johndaniel:
its paid service, just like back in days for HTC when there was a team who had a paid service to make s-off.
[Sony Xperia 1 III] dima_vy:
Guys, great thread

but i'd like to understand, i have XQ-BQ52 from UK. And i'm in Israel, which according to carrier_policy.xml belongs to MEA1 region. So 5G works, but volte and vowifi doesn't work. If i will flash SEA firmware should it enable volte?

Thank you
[Sony Xperia 1 III] bentree:
I don't suppose you could elaborate on how you converted the MBN files to the required EFS files? I'm in Australia and have found the needed MBN files from a compatible chipset phone. Unfortunately I have no Idea how to convert the files or where to put them exactly. Many thanks in advance.
[Sony Xperia 1 III] johndaniel:
Did you try? I tried and never got my carrier radio to turn on. Seems only the same model number with different regions based on what bands are open for it works.
[Sony Xperia 1 III] johndaniel:
This method if adding efs files , does in turn make volte enable . But relocking bootloader to get ota makes the volte toggle disappear due to the fact we cant edit the build.prop file when non rooted. People with asian region phone models can flash sea firmware but those model from us or europe cant . The whole flash with newflasher to update ota is hassle.

So if anyone has a method to enable volte toggle(edit build.prop) without root on locked bootloader, then its a big win win for all.
[Sony Xperia 1 III] dima_vy:
I'm afraid, that nobody except Sony is not able to do it. If they won't fix it, I think that in a couple of years I won't be able to use this phone. According to Israeli ministry of communication 3Rd generation network will be turned off maximum on December 31, 2025. But I think operators will do it earlier, to free up frequency bands. If till that day there won't be solution, it will be really disappointing, because phone, as a phone will become unusable...
[Sony Xperia 1 III] GeramanX:
Can you give me a hand? I'm in Mexico and just got my Xperia 1 III but can't get 5G working :(
[Sony Xperia 1 III] dima_vy:
Do you need a root to perform these changes?
[Sony Xperia 1 III] GeramanX:
Looks like it can be done without rooting the device.
[Sony Xperia 1 III] dima_vy:
Did you succeed to make the changes?
[Sony Xperia 1 III] GeramanX:

[Sony Xperia 1 III] dima_vy:
In my case I have 5g working out of the box, but volte and vowifi doesn't work. Right now vowifi may be helpful, but in a few years phone without VoLte simply won't work...
[Sony Xperia 1 III] johndaniel:
If only 5g is required , copy carrier confg file to policyman folder under efs explorer , then flash original boot and relock. Hope it helps with 5g. Get your mbn from any phone providing in your region then expand it or use notepad++ open mbn with it ,find the carrier config syntax and copy .you can even try any carrier confg file , usually 5g is easy to get
[Sony Xperia 1 III] johndaniel:
If u have rooted and unlocked phone u can get volte and vowifi. Need to find the right mbn for your carrier from oneplus or any Snapdragon phone.
[Sony Xperia 1 III] johndaniel:
Problem is ota is out of question and if you do flash with newflasher , the modem files/efs files get cleared , so your back to rooting and again copying files to efs explorer. What i do now i wait 2 or 3 months then update , that way it takes me an hour to do the whole process of rooting and copying efs files. Whole problem is to get volte option under mobile network . Without root for certain regions it doesn't show no matter you flash sea or HK firmware.
[Sony Xperia 1 III] johndaniel:
https://johnbel.github.io/

Download the efs tools .

Run cmd and run the below command.

EfsTools.exe extractMbn -i mcfg_sw.mbn -p mcfg

Mcfg_sw.mbn is your mbn file name. Mcfg is the folder it will create in that root folder where files will be extracted.
[Sony Xperia 1 III] GeramanX:
Thank God you're here John! Is it possible that you can help me through teamviewer?

Please help me, I'll be eternally grateful for it.
[Sony Xperia 1 III] dima_vy:
I have unlocked but not rooted phone. I don't want to root it... Mainly prefer to keep camera and other apps to work as original. Is there any way to do it without root rights?
[Sony Xperia 1 III] johndaniel:
I dont have a pc now ,iam traveling as of now. First find the phone that has your carrier mbn, then extract it, follow the sony bootloader unlock first, then root the boot image . use the adb shell command as per htcmage and follow it to the teeth . Get it open on pc in efs file explorer then just copy the carrier config file to the folder named policyman. Flash back your boot image from the newflasher firmware you downloaded , relock bootloader. Now you have your stock rom with 5g and ota updates also Widevine L1. Also you should be thanking htcmage for this, i just followed what he did and did a lot of expirments based on that.
[Sony Xperia 1 III] GeramanX:
Hi John, I was wondering if you have time to help me, I hope you're OK in your trip and having lots of fun.
[Sony Xperia 1 III] GeramanX:
Hi John! Can you give me a hand with my phone? I´m afraid i can damage my phone if I screw up :(
[Sony Xperia 1 III] johndaniel:
You can follow the method done here, ur highly unliky to screw your phone with new flasher or rooting. At all anything happens use sony Campanian app. Go through bootloader unlock, root device , then open efs explorer. Copy files from the mbn from your region. All steps in between u require are said before in this thread.

Just go through each page , and its easy.
[Sony Xperia 1 III] GeramanX:
I´m so scared, I beg you please :(
[Sony Xperia 1 III] johndaniel:
I dont understand, what help from me you require, u haven't even said wat u tried.start somewhere , then see where you get stuck. Usually people start at a point and ask help based on that. Iam confused.
[Sony Xperia 1 III] misquia:
HI, I already have 5G and VoLTE by default with T-Mobile on this phone, but I'm trying to get VoWifi. My phone is already unlocked and rooted. I also have the MBN from a Mi11 Ultra (same chipset) I can use. I have QPST tools installed and managed to connect with EFS explorer. I'm just completely lost on what to do next. I read something about EFS tools to convert a file to use, but I can't make sense of it. Can anyone provide help on what I should do next?
[Sony Xperia 1 III] Ainz_Ooal_Gown:
same boat did you ever get it fixed?
[Sony Xperia 1 III] misquia:
Nope, unfortunately not. I tried looking around other phones' forums too for ways to use EFS explorer to get VoWifi, but they seemed phone specific.
[Sony Xperia 1 III] Ainz_Ooal_Gown:
damn
[Sony Xperia 1 III] johndaniel:
To get vowifi, u need to copy files from another mbn. Some carrier specific mbn contains volte but some doesnt have vowifi, to obtain that,get mbn from another device for your carrier

doesnt matter same chipset, even old chipset can get volte as long as its for your carrier.

For starter's check for old xperia devices sold for the country. Even samsung devices firmware has mbn. Vowifi is inside nv and modem folder . To convert mbn to efs files ,check previous post.
[Sony Xperia 1 III] anmolkakkar:
Hey @johndaniel

Thanks for sharing this for the Indian carriers, and all the intermediate steps that were necessary for getting this enabled. Additionally, kudos to @htcmage for the detailed explanation. A combination of both your work has allowed to enable this.

I wanted to ask how can I add both Airtel and Reliance .mbn files to my phone because when I try to extract the files from both these respective .mbn files, the EfsTool creates multiple files (in respective different folders) with same suffix at end of file names (e.g. carrier_policy.xml__E1FF_F) which tend to replace/overwrite the existing files of phone. I tried putting Reliance's files first (that had the same suffix), it worked but Airtel didn't coz I hadn't copied those over because of this. But when I tried to put Airtel's files, it not only didn't work but Reliance also stopped working then. I am trying to make both these carrier's VoLTE work. Both the sims work just fine in literally any other phone.

Also, do I need to copy ALL the files that this tool extracts (it's a long cumbersome process) or do I need to copy some specific files only. Please help clarify this and the steps I need to take for making both these work in my 5 III (XQ-BQ72 Taiwan variant).
[Sony Xperia 1 III] johndaniel:
U need to rename , those files and remove the _E1FF_F. then copy all files as per the folder.

yes you need to copy all files. For second sim , u need to edit and replace the 'subscription 1' file, under /data. And finally yes its long process, but it is worth the effort, since volte, wifi calling and 5g(depending on region and coverage) can be activated via this method, be used for what the price we pay for this phone.
[Sony Xperia 1 III] anmolkakkar:
Thanks for clarifying.

Quick questions:

"For second sim , u need to edit and replace the 'subscription 1' file, under /data", do I need to rename that file on laptop with this name i found in the phone and then upload it there after deleting it in phone? Sorry, I didn't fully understand what I need to do for this. Could you please elaborate a bit more?

Additionally, when I rename the files and remove the suffix on laptop before uploading, won't the files in the 2 respective mcfg folders have same names for quite a few of the files and keep overriding each other when I indeed upload? Will this still make it work for both the SIMs?

UPDATE:

1. Had to reflash the whole firmware and repeat this whole process as the networks weren't getting registered for some reason. Renamed the files and uploaded just Reliance and VoLTE only is working (no VoWifi).

2. For Airtel to work (haven't added these files to the phone yet as I am not sure how to add given the same filenames and it being getting replace by one another), what exactly do I need to do so that Reliance also keeps working? @johndaniel)
[Sony Xperia 1 III] anmolkakkar:
Also @johndaniel Once I have renamed and removed the suffix from the different extracted files for these 2 different MBNs (Airtel and Reliance carriers), there are still many files that have the same name in many of their folders. Which one should I upload first to avoid having those replaced by one another. I really need help uploading both uniquely so that VoLTE and VoWifi (hopefully) starts working for both these SIMs parallely.

Could you please provide that clarity and help me with it? That would be greatly appreciated.

How I enable 5g in Sony xperia 5 ii
[Sony Xperia 1 III] kevinmcmurtrie:
Does anyone know a trick to get the Qualcomm driver working in a virtual machine? I can dedicate the USB bus to a Windows VM in VirtualBox but only MTP is seen. I already tried disabling USB 3.0 since that's unstable on my phone.

A Windows VM image is trivial to get (Microsoft offers them for free). Real Windows is a bit harder but maybe I can convert the VM image to a bootable image. I'd also need to unplug all the storage on my motherboard (not easy) so it's not destroyed by malware when downloading from the typical web sites claiming to host Android tools. The last Windows VM I used seems pretty wrecked at the moment. (https://band.radio/diag seems safest, but I still don't trust anything)
[Sony Xperia 1 III] Xperia_xz3:
Main problem how to root xperia 5 ii Docomo then follow your step
[Sony Xperia 1 III] johndaniel:
Follow the steps to root , then enable the Qualcomm ports, u can use the mbn push method from the other post in this forum, to push mbn . Remember airtel have started to whitelist phones, which means even if u push mbn for airtel , it wont work unless they enable volte from the carrier side. Jio and other carriers works for volte and wifi calling.

5g for india is a no go. They have whitelisted phone models , sony is not in it. So no matter how much u edit carrier config it wont work. 5g we have to wait till they enable from carrier side.
[Sony Xperia 1 III] ralf_waldo:
Hi @johndaniel , can you please elaborate in technical terms what does whitelisting mean from carriers like Airtel & Jio. I have been trying to explain them but not to any success.

I have Sony Xperia 1 IV which supports volte for Airtel out of box. 5G for Airtel can be enabled by a little tweak in disabling the dsds and enabling it again. This works for e-sim versions phone.

5G for jio is not yet supported even after above tweak.
