Sony Xperia 1 III doesn't support 5G Standalone (SA) network at hardware level. Airtel uses existing 4G network infra (Non standalone - NSA) to offer 5G speeds. So Jio 5G will never work due to hardware limitations.

[Sony Xperia 5 III] Hendikins:
A quick update for the Telstra users around here: I finally got VoWiFi working. This is in addition to getting VoLTE working (as described earlier in the thread) and 5G (using carrier_policy.xml).

Turns out you need to use EFS Explorer to replace /data/iwlan_s2b_config.xml (and/or /data/iwlan_s2b_config.xml_Subscription01 as applicable) with the version from some variety of Pixel (found on a Whirlpool thread). I've attached the file so you don't have to hunt for it.

Edit for clarity: You must have VoLTE working using the method in my earlier post before doing this. Also, screenshot.
[Sony Xperia 5 III] bentree:
Tried multiple times, even re-flashed modem partition and still unable to get VOWIFI to register. Can you link the whirlpool thread?

Cheers, Ben.
[Sony Xperia 5 III] Hendikins:
The Whirlpool thread isn't particularly useful - it's just where I managed to obtain the MBN file.

I've only verified this works on the XQ-BQ62 under the specific conditions of:

* Flash modem partition back to stock

* Use the PDC tool to install and activate the Telstra MBN from the Sony firmware

* Install Shizuku and Pixel IMS, enable VoLTE

* Reboot

Edit: If activating the Telstra MBN doesn't persist after restart and you don't need the ROW Commercial one, use PDC tool to remove the ROW Commercial MBN and activate the Telstra one. You can reinstall ROW Commercial later if the need arises.

* Overwrite /policyman/carrier_policy.xml and /policyman/carrier_policy.xml_Subscription01

* Reboot, check 5G works

* Overwrite /data/iwlan_s2b_config.xml and /data/iwlan_s2b_config.xml_Subscription01

* Reboot, enable VoWiFi

I've also attached a diff to show the differences between the Sony and Pixel versions of iwlan_s2b_config.xml.

Edit: And a screenshot of the device in flight mode with WiFi enabled making a call to a test number.

Edit: Reboot after enabling VoLTE, not before.
[Sony Xperia 5 III] bentree:
Well I really can't get it to work, using your steps exactly. Only variance I can think of is the MBN file. Can you share your MBN file?

Cheers, Ben.
[Sony Xperia 5 III] Hendikins:
See attached ZIP file for the exact MBN and XML files I used.
[Sony Xperia 5 III] Hendikins:
Turns out I had a step out of order. Enable VoLTE with Pixel IMS first, then reboot. Remove ROW Commercial if it doesn't cooperate.

Edit: mcfg_autoselect_by_uim might also work, but I don't need to go down that route so I haven't tried it.

Have now validated using my XQ-BQ72.
[Sony Xperia 5 III] bentree:
Awesome will try again tonight. Although I have been down this rabbit hole before but maybe luck is with me tonight.
[Sony Xperia 5 III] bentree:
So after following your steps using the provided MBN file and xml files. I still have had no luck getting VOWIFI to work. The phone refuses to register VOWIFI in the services menu. Volte still works fine.
[Sony Xperia 5 III] bentree:
What firmware region do you have on your phone? Is it hongkong, taiwan, or south east asia?
[Sony Xperia 5 III] Hendikins:
US on the XQ-BQ62, TW on the XQ-BQ72. They all come with the same MBNs though.

What step is this failing at? Are the changes to wlan_s2b_config.xml persisting?
[Sony Xperia 5 III] bentree:
Yes wlan_s2b_config.xml is persisting but it doesn't seem to allow VOWIFI to activate. #*#*4636#*#* show ims status as registered and volte registered but nothing else.
[Sony Xperia 5 III] Hendikins:
Out of interest, how did you enable VoWiFi? Through Pixel IMS or Settings?
[Sony Xperia 5 III] bentree:
Via VOenabler originally, it's the root version of Pixel IMS. but then I re-flashed modem from scratch and enable via Pixel IMS. didn't make a difference tho.
[Sony Xperia 5 III] Hendikins:
You may need to disable/enable in the Settings app - the first time you do that it asks you to accept some conditions or something (I didn't read it, I just accepted it).
[Sony Xperia 5 III] bentree:
I have tried via the settings app but I never got anything about a warning.
[Sony Xperia 5 III] Hendikins:
Just toggled it, it's a warning that VoWiFi uses location services.

Which region firmware did you try this with, and was the device flashed back to stock before starting?

Edit: I've also had a look, and the MBN files for PDX214 (5 III) and PDX215 (1 III) aren't identical (sha1sums don't match). I'm not currently in a position to dissect them and see if it matters. I've attached the Aussie MBNs for PDX215.
[Sony Xperia 5 III] bentree:
No warning on my end when I toggle WIFI Calling.

I'm running stock Rom but rooted because I needed to get root to have volte originally. Don't really want the headache of wiping and starting over with a locked bootloader.

Originally I tried your method with the Telstra MBN that I extracted from the stock 1III firmware. That was why I asked for a copy of your MBN just incase something was different.

It appears that there is definitely something different about the 1III compared to the 5III. Maybe I can try loading a hardware setup for the 5III using PDC tool and see if that changes anything.

I know that wifi calling is enabled for my sim as i have tested it on a samsung device.

Cheers, Bentree
[Sony Xperia 5 III] bentree:
So after a complete factory reset of the phone I have gotten closer to getting VOWIFI. If I don't transfer your modified wlan_s2b_config.xml then I don't get VoWIFI but if I transfer the it over then I still don't get VOWIFI to register on #*#*4636*#*# but if I try to make a phone call while connected to WIFI with WIFI Calling enabled. The call will fail to connect. It'll just eventually time out in the dialer app. So it is definitely trying to connect. Obviously there must be something that needs changing in wlan_s2b_config.xml for it to finally connect and register.
[Sony Xperia 5 III] Hendikins:
I take it you've ruled out firewall issues?

Also, called in a favour from someone I know who retired a 1 III recently, so I'll have one to poke at soon (but it won't replace my 5 IIIs for daily driving).
[Sony Xperia 5 III] bentree:
Yeah tried on different WIFI and disabled any form of firewall too. Well fingers crossed you can get something out of the 1iii.
[Sony Xperia 5 III] kakashield:
Thanks, got it working but similar to your screenshot, once VoWiFi is working (after replacing the files using EFS Explorer), IMS status shows that Voice over LTE is unavailable.

VoLTE was supposedly available (showed as available in IMS status) previously after copying MBN files using efstools. Just wanted to see if you had the same issue. Thanks.
[Sony Xperia 5 III] Hendikins:
This is normal - Voice over LTE will be unavailable when connected to Voice over WiFi and vice versa.
[Sony Xperia 5 III] bentree:
Did you have any luck with the 1III yet? I tried everything and still can't get it. Even went and got a brand new SIM just in case that had issues.

Cheers, Bentree
[Sony Xperia 5 III] Hendikins:
Still waiting for the person who has it to clear their data and send it, unfortunately.
[Sony Xperia 5 III] bentree:
Well it looks like you don't need to worry about it now.

I have finally got Wifi calling working.

I had to load a different HW configuration in the PDC tool.

In the modem files, I found the Qualcomm default hardware MBN file. It's located in Lahaina, Standalone, LA, DSDS_CDMAless, DSDS_CDMAless.mbn. Once I loaded that, I then loaded the Telstra.mbn

After that I transferred the 4 files using EFS explorer and enabled WIFI calling.

Instantly I got a text message from Telstra saying that I had connected a "new device" to the network and that Wifi calling would be provisioned.

Which is strange because I have tested my SIM in a Samsung S9 and wifi calling worked on it. So it shouldn't have needed to be provisioned.

My guess is that by loading the default hardware MBN file it allows the phone to request provisioning of WIFI calling?

Anyway the good news is that WIFI calling now works with telstra on a XQ-BC72 device.

Cheers, Bentree
[Sony Xperia 5 III] Hendikins:
Interesting - I didn't have to do that with the 5 III. Glad to hear you've got it working.
[Sony Xperia 5 III] bentree:
Just an update to say that it's still working and that not only is WIFI calling working but so is WIFI sms. Just to be clear on what I mean by that, (I don't mean RCS sms) I mean standard plain old sms but sent via WIFI.

Cheers, Bentree
[Sony Xperia 5 III] Hendikins:
Neat. Not something I've tried because I use RCS on SIM 1 and generally don't use SMS on SIM 2, but good to know.
[Sony Xperia 5 III] bentree:
I have a few friends with Apple phones, so they get the good old SMS only messages. Only found out that it works because the network went down up here and I was getting messages from friends still via sms on WIFI.

Cheers, Bentree
[Sony Xperia 5 III] tlc_at_home:
Hi Folks

I need a bit of help here with this. I have followed this guide and was successful with enabling VoLTE on my Xperia 5 III. The IMS status is that everything is fine with VoLTE. However, I haven't yet re-lock bootloader and unrooted the phone. I thought I would test it before locking to save unlocking if it didn't work.

I am on VodaFone Australia and I tried to make calls with no success. Do I need to lock it for this to work? It shouldn't matter.
[Sony Xperia 5 III] bentree:
How do you know it didn't work? What have you tried? Just saying it it didn't work doesn't give us much to work with tho.

Cheers, Bentree
[Sony Xperia 5 III] Hendikins:
I never had any luck with VoLTE using the EfsTools method of loading MBNs on my 5 IIIs. Since you're on an Australian carrier and the device firmware ships with the required MBN file, I recommend using the PDC Tool instead. Even though I use Telstra, none of the instructions in the linked post are specific to Telstra.
[Sony Xperia 5 III] tlc_at_home:
Thanks for reaching to help.

I tried to make and receive calls and nothing happens.

I have been reviewing the process I did following the guide and appears that I didn't patch the boot.img file. There were no instructions for this step. Would this have any implications on VoLTE not working now. Do I have to revoke superuser and lock the OS again?
[Sony Xperia 5 III] tlc_at_home:
May I ask you to explain this step as it's not quite clear to me:

Remember the original boot.img we have before patching copy that file into platform tools and replace it with the patched boot_magisk.img

It appears that you want to copy a file into a directory and then overwrite it.
[Sony Xperia 5 III] bentree:
Hang on, if you never patched the boot.img then you never had root? If you never had root, then there is no way you could have followed the rest of the instructions.

Please start over. Also I am fairly certain that the 1III had VOLTE enabled with Vodaphone out of the box?

Cheers, Bentree
[Sony Xperia 5 III] bentree:
This is for the re-locking of the phone. Only need to do this once you have confirmed that you have VOLTE working. This is the original boot.img that you extracted from the original firmware. You have to flash it to remove root from phone.

Cheers, Bentree
[Sony Xperia 5 III] tlc_at_home:
If I don't have root how can I do this:

C:\Users\Tony\Downloads\platform-tools_r35.0.0-windows\platform-tools>adb shell

XQ-BQ72:/ $ su

XQ-BQ72:/ #

XQ-BQ72:/ #

XQ-BQ72:/ # setprop sys.usb.config diag,serial_cdev,rmnet,adb

C:\Users\Tony\Downloads\platform-tools_r35.0.0-windows\platform-tools>
[Sony Xperia 5 III] bentree:
Then you do have root, the part you was confused with was un-rooting then. Looks you are going to try the PDC method?

Cheers, Bentree
[Sony Xperia 5 III] Hendikins:
Unfortunately not the case for any Australian carrier with the 5 III. I used to use Optus and also tested it with Vodafone.
[Sony Xperia 5 III] tlc_at_home:
I think I got it working. I have made calls and received calls. Even the VoWifi seems to work.

Now I have to unroot and lock it. After that I will test again.
[Sony Xperia 5 III] bentree:
Sorry my mistake, I was thinking of the 1IV which has VOLTE on Vodafone and Optus but not Telstra.

Cheers, Bentree.

Edit: Also the 1V has VOLTE on Optus and Vodafone just not Telstra.
[Sony Xperia 5 III] bentree:
Awesome!! Keep us updated. Any problems feel free to ask :)

Cheers, Bentree
[Sony Xperia 5 III] tlc_at_home:
All systems are "GO". To quote, The Thunderbirds. haha

Everything is working now. My Sony Xperia 5 III is able to make calls on VodaFone.

Now I just have to restore my 148 apps to working order.

Thanks so much for all your help with this.

Hello, attempting this from australia- model 5 iii,(xq-bq72) with Lebara(vodafone). I suck at computers/all this hacking stuff. ill be needing a lot of help.

currently trying to "Prepare the device for Rooting" i have completed all steps prior to this.

I am stuck on the "fastboot oem unlock 0xYOURKEY"

I input the code generated by sony, and it shows the info in the image.

Any help is greatly appreciated
[Sony Xperia 5 III] tlc_at_home:
From what you say my advice would be to find a friend that's a computer nerd. You don't seem confident to succeed with this as you are about undertake major system updates. I got to the same point with the same error and I figured out what to do to get past it. Took me 3 days working through all the issues that arose by following this guide.

Are you ready for that?

we can use modem files in others rom to get 5G and volte for almost japanese model, but....no with docomo model, maybe...maybe you can try with modem file from sea rom, if phone still boot up and just no sim signal, try flash 2 oem_other files from stock docomo's rom...well, just maybe, i don't try it on docomo yet, but with au and softbank we can get dual sim, 5G and volte.
[Sony Xperia 5 III] maheshfuture:
Hi. Can you please explain how to flash OEM & Modem only files? What needs to be in the newflasher folder?

I have got a 5 iii SOG05 with me.
[Sony Xperia 5 III] ctfish21:
Any update? I am looking for an answer to the same. Will it make any difference to the mobile other than adding volte, vowifi and 5g access to the mobile..

will the advanced computational photography algorithms by sony and other pre-loaded content be inaccessible after this?
[Sony Xperia 5 III] Lavievn:
it's depends on which your device you have and what rom you're using, each has 2,3 or more OEM/Modem files. As your device is SOG05, it's maybe harder

Some devices like the 1iii and 5iii Au models have different procedures. I once had some problems with the 1iii Au model. We just need to flash the rom of the BC-72 model directly, then flash the oem files without the X-flash word from the rom of the original SOG03 model, after this step the device will still recognize 2 sims but no signal, now flash the modem files of the bc-72 rom (sea), then restart the device and may need to restart a few times, the device will recognize 2 sims and full volte, however still no NFC function and still some Japanese applications of the original version. This is what I use for most devices but sometimes some devices still don't have good results, you may have to try again with flashing using the bc-42 rom first then the oem files of the original rom and the modem of the bc-72 rom. Basically we need a rom that our device can boot into android and that rom supports 2 sims (bc-72, BC-42) but will lose signal, the oem files will install some Japanese software but will help the device regain signal, the modem of the SEA, RU version... will help the device recognize all features like volte... Sometimes there will be unforeseen errors, recently I tried on the 1V Au model and lost all sound after flashing 3 modem files of the SEA model, then removed 1 file and it was back to normal, so you may have to try many times to be successful.

So, as your question, it's all oem/modem files in once flash, but if it's fail, try take out 1 or more files and try again, oem files make your sim working, but we don't know wich oem file is content japanese app and wich file make both sim work, and modem files make the signal goes global.
[Sony Xperia 5 III] chaitu_vemuri:

[Sony Xperia 5 III] SystemOver:
Unfortunately I can get only 5G on Sony Xperia Pro-I with Telstra network, and I don't know how to get IMS register working
[Sony Xperia 5 III] Hendikins:
What steps did you perform on your device? With the 5 III on Telstra I only had success using the PDC tool and the Telstra MBN hiding in the Sony firmware. Using EFSTools and flashing MBNs from other devices got me nowhere.
[Sony Xperia 5 III] sla73:
Hey any update on this, I am at the same point.. thnx
[Sony Xperia 5 III] sla73:
Hey @Hendikins

I have attempted to get VoLTE working on my XQ-BC72 but without success.

I have a rooted phone (Magiks installed), with 61.2.A.0.472A SEA Firmware.

I have managed to copy the MBN and Xml files that you shared using efstools

5G works

Oh and Pixel IMS, shows VoLTE Supported and Shinzu is working.

But IMS is not registered.. Scratching my head, hope you can advise pls..

P.S haven't applied the xperia-band-unlock

Cheers sla73
[Sony Xperia 5 III] Hendikins:
I have not had success using efstools on my XQ-BQ62 and XQ-BQ72 to enable Telstra VoLTE. The abridged version of what worked for me on Telstra:

Download latest firmware for your device and extract MBNs from it

Obtain QPST

Use the PDC Tool to upload and activate the Telstra MBN

Per @bentree you may also need to upload and activate DSDS_CDMAless.mbn (hardware MBN)

Use EFS Explorer to replace the following files (Subscription01 files are for SIM2, iwlan_s2b_config.xml is specifically for Telstra VoWiFi):

/policyman/carrier_policy.xml

/policyman/carrier_policy.xml_Subscription01

/data/iwlan_s2b_config.xml

/data/iwlan_s2b_config.xml_Subscription01

Enable VoLTE/VoWiFi using Pixel IMS

Note: These instructions are specifically for

Australian

carriers, because the firmware for the Xperia 1/5 Mk III ships with MBNs for Telstra/Optus/Vodafone that are unused.
[Sony Xperia 5 III] bentree:
Just some info you may like to know also @Hendikins. The 1VI has volte on all 3 carriers in Aus. So I extracted the MBN file from it and it uses the one MBN file for multiple carriers.

I dismantled the MBN and flashed it via EFS Tools and it gives you VOLTE. Even has the correct iwlan_s2b_config.xml included. One file has to be removed for WIFI calling to work tho.

The file is called "override config" and it's located under the folder called "efsprofiles".

It's there to deliberately block the ability to use WIFI Calling. Not sure why tho.

Anyway enjoy your Wednesday.

Cheers, Bentree
[Sony Xperia 5 III] Hendikins:
That is interesting!

I believe this relates to 000 - something about not wanting you to use VoWiFi for emergency calls if a mobile network is available because they can't get location data.

Edit: It should be locking the calling preference to prefer mobile network and only use VoWiFi if it's unavailable, rather than disabling VoWiFi entirely.
[Sony Xperia 5 III] sla73:
Hey @bentree, Thanks, are you saying that I can extract the mbn file from the 1 VI (XQ-EC72) 69.0.A.2.26 (HK) firmware and use it on my 1 III (XQ-BC72)?
[Sony Xperia 5 III] sla73:
Thank you @Hendikins.
[Sony Xperia 5 III] bentree:
Yes that is correct, you need to flash it via EFStools tho. It's located in the "ROW" folder in the 1VI modem files.

Cheers, Bentree
[Sony Xperia 5 III] sla73:
Thanks,

So do you have a copy of that file, how would I get it from the FW if I don't have a 1 VI (XQ-EC72) device?
[Sony Xperia 5 III] bentree:
No, as I'm currently travelling for the rest of the week and don't have access to my computer.

Just use the Sony firmware downloader to download the firmware and extract the modem files.
[Sony Xperia 5 III] sla73:
Thank you, I did some quick research and found UnSin, just need to figure out which *nbm file to use..
[Sony Xperia 5 III] sla73:
Found the ROW nbm file in 1 VI (XQ-EC72) 69.0.A.2.26 (HK) and..... that didn't work :(
[Sony Xperia 5 III] bentree:
Strange try the one in CommercialJ4 folder instead? But really strange because I just flashed the commercial one and it worked....

Cheers, Bentree
[Sony Xperia 5 III] sla73:
Have a feeling I might need to wipe and start again.. or am I missing something? I tried to make a 5G call with just NV/LTE no go..
[Sony Xperia 5 III] sla73:
one last question, should Magisk, Shizuku and Pixel IMS (bluehouse) be turned off when flashing?
[Sony Xperia 5 III] bentree:
It shouldn't matter as when you flash, you are modifying a partition that is seperate to what they do.
[Sony Xperia 5 III] Hendikins:
Tried this on my XQ-BQ62 with LineageOS 21. Doesn't work with either MBN.
[Sony Xperia 5 III] bentree:
Well colour me confused then.

I have no idea what i've done then...
[Sony Xperia 5 III] sla73:
I wonder if it has anything to do with initial image the phone is flashed with?
[Sony Xperia 5 III] sla73:
P.S. I managed to figure out how to use PDC, no cigar either.. I did see the Telstra profile there too..
[Sony Xperia 5 III] hansmoleman:
Where's everyone getting the QPST tool from?
[Sony Xperia 5 III] sla73:
QPST Tool v2.7.496 for Windows

Download the official QPST Tool v2.7.496, which enables you to flash the stock firmware on your Qualcomm smartphones and tablets.

qpsttool.com
[Sony Xperia 5 III] hansmoleman:
Thanks, would you happen to know why the files are hosted on a website littered with ads and fake download links? Are qualcomm no longer maintaining the software themselves?
[Sony Xperia 5 III] Hendikins:
I don't believe the tool was ever intended to be available to the public.
[Sony Xperia 5 III] hansmoleman:
Gotcha. Thanks for the reply
[Sony Xperia 5 III] ausben:
How do we update the modem files for the second sim for dual sim devices. efstools 1.4 worked for sim 1, but I see you need the modded version of efttools 1.2 to get the sim switch, but efstools 1.2 won't connect. Anyone had any luck getting the second sim modem done?
[Sony Xperia 5 III] Hendikins:
The solution for Xperia 1/5 III devices on Telstra/Optus/Vodafone is to use the PDC tool from QPST instead, along with the MBNs from the latest firmware for the device. VoLTE just works on both SIMs when you do it that way.
[Sony Xperia 5 III] ausben:
Thanks, is there any guides for using the PDC tool with the MBN?

Edit: found this https://xdaforums.com/t/guide-no-ro...ther-qualcomm-powered-lg-devices-too.4343655/ which gives enough info on how to use PDC
