I'm having an issue with the PDC tool. I've got it loaded and can remove carriers, but no new carriers appear when I load a new MBN tile. the file i'm using has worked to enable VoLTE on sim 1 using EFS tools, but when I load it into PDC I don't get any new carriers?
[Sony Xperia 5 III] Hendikins:
You need to use an MBN that's specifically for your device when using the PDC tool - it will not work with random MBNs.

Edit: You should probably also reflash the stock modem.sin file for your device if you've been messing around with EfsTools before using the PDC tool.

The firmware for Xperia 1/5 II, III and IV devices contains MBN files for Telstra, Optus and Vodafone Australia that aren't used by default.

I've attached the MBNs for the Xperia 5 III to one of my earlier posts in the thread. If you're using the 1 III, 1 II, 5 II, 1 IV or 5 IV you can download the latest firmware using XperiFirm and extract the relevant MBNs from it.
[Sony Xperia 5 III] ausben:
I've got a 1 V, but can't find Telstra in the extracted modem sin file. Do I just load the ROW/commercial one?
[Sony Xperia 5 III] Hendikins:
The instructions in this thread apply to the II, III and IV only, not the V or VI.
[Sony Xperia 5 III] 0Bradda:
I got this far, with many errors and hiccups (got them all sorted as I went), everything seemed to work but it still drops to 3G for calls... No idea where to go from here. What checks can I do?

I have an XQ-BQ72, use and Aldi SIM(I've tried the sim in an Xperia 1 VI and VoLTE worked).
[Sony Xperia 5 III] Hendikins:
ALDI has MVNO operations in several countries - which one are you using?
[Sony Xperia 5 III] 0Bradda:
Telstra is the network used here.
[Sony Xperia 5 III] Hendikins:
I'm using an XQ-BQ72 and XQ-BQ62 on Telstra with VoLTE, 5G and VoWiFi enabled.

I would suggest doing the following:

Reflash the stock modem.sin file since you've been doing stuff to the device.

Grab the file I've attached to this post (contains Telstra MBN from the device firmware, along with modified XML files to enable 5G and VoWiFi)

Use the PDC tool from QPST to upload and enable the Telstra MBN

Use EFS Explorer to replace the carrier_policy.xml and iwlan_s2b_config.xml files

Enable VoLTE and VoWiFi using Pixel IMS

You can check the posts from @bentree and myself in this thread for more information and potential hiccups.
[Sony Xperia 5 III] 0Bradda:
Sorry man, I have no expertise in this area and have fried my brain trying to work it out. I can't even work out how to follow you instructions...
[Sony Xperia 5 III] 0Bradda:
I'm trying to start from scratch and stuff isn't working. I have no idea what's wrong. I'd literally pay someone to help fix this.
[Sony Xperia 5 III] bentree:
Then I would recommend that you go buy a different phone and sell your old one. This isn't something that someone can come and do for you.

Sadly that's just how it goes.

Cheers, Bentree
[Sony Xperia 5 III] 0Bradda:
Yeah my 5III's screen is cracked so I just ordered 1VI. One way to solve my problems!
[Sony Xperia 5 III] bentree:
Nice! I just can't afford the cost of one sadly :(
[Sony Xperia 5 III] alrafa37:
Are these steps under the assumption that the phone is rooted?

My bootloader is unlocked but I am wondering if I have to root my phone to follow these steps or should mix the steps with the first post in this thread.
[Sony Xperia 5 III] Hendikins:
That summary assumes the phone is rooted, you have QPST installed and have previously used EfsTools. It's also specifically for Telstra (Australia), although it should work for Optus and Vodafone as well if you flash the respective MBNs and skip overwriting the iwlan_s2b_config.xml files.
[Sony Xperia 5 III] alrafa37:
Thank you very much.

I realised I was a bit silly and thought Bootloader Unlocked allowed -yes was the same as having the bootloader unlocked. I will have to go through all the steps.
[Sony Xperia 5 III] shadowdrake05:
I'm having a heck of a time getting PDC tool to recognize my phone.

I downloaded the qpst tools as linked (so latest version). I installed the driver and manually added it for each of the XQ-BC62 devices in device manager (using Qualcomm HS-USB Diagnostics 9091). I narrowed it down to which COM port has the device show up as LAHAINA in QPST Configuration (in this case, COM3). EFS Explorer works in this case.

PDC Tools does not. I have tried a bunch of different configurations and can't get anything to show up in PDC Tools.

I'm attempting to enable VoWiFi on a 1 iii with T-Mobile as my carrier... so I'm trying to follow @bentree 's recommendation to flash the generic CDMALess file then the carrier file again using PDC Tools. But can't get PDC Tools to show any devices.

Edit: after a slightly frustrating time I figured it out. But instead of being like the couple others here who simply said they figured it out and never stated what it was, you need to run the following in adb shell (as root):

setprop sys.usb.config diag,serial_cdev,rmnet,adb

This will make the phone disconnect, and reconnect. Reinstall the COM port driver if required. In this mode QPST config will still show the device name but it will also show up correctly in PDC Tools.

Edit 2: Still no luck getting VoWiFi working though. I have no idea where the CDMALess file Bentree got based on his path. I tried flashing one of the common files from my device, then flashed the TMO Commercial MBN again. I copied iwlan_s2b_config.xml over to the device again.

With Shizuku and wifi calling turned on, I can see the wifi calling setting and can turn it on but it does nothing.

Thoughts?
[Sony Xperia 5 III] deltarz:
I cant get 5G to work on vodafone Australia, regardless of if I flash the provided mbn, the m9 mbns, the random pixel mbn off whirlpool or the mbns from the 5 iii a13 firmware, or if i efstools it in. the 5g icon flashes briefly on reboot and then disappears, 4g volte works, vowifi gets the logo but does not work and just hangs up on call, and forcing NR only in 4636 immediately gives an out of range error. I didnt know which xperiafirm to flash tho so i used "global vodafone LC not net locked" if that matters. uploaded the carrier_policy.xml from the one from the OP, and i deleted some disable_5g file in the policyman folder if that changes anything.

Maybe I'll try to buy a $5 telstra or optus card to test if 5g works on those?

Edit: never mind, 5g worked, turns out voice calls just fall back to volte... and forcing nr only doesnt work cos everything is a dual purpose tower.

but i cant go vowifi to work, anyone got it working?
[Sony Xperia 5 III] bentree:
Anyone able to supply S21 MBN files? I can't open the modem.bin files, just get given errors each time.
[Sony Xperia 5 III] Yeme:
I updated this guide, you can extract the S21 MBN files from your firmware using root and Solid Explorer.
[Sony Xperia 5 III] bentree:
Yes I know about extracting from factory Sony Firmware, that is easy. I need to get S21 MBN files as S21 was only device with same chipset that was released in my area with volte and vowifi. Thats why I need S21 mbn files.
[Sony Xperia 5 III] Cristian.cojocariu:
So, I just updated to firmware 61.2.a.0.396, and it definitely doesn't work anymore.

I think the update went and rewrote the mbn and xml files.
[Sony Xperia 5 III] bentree:
Yeah each time an update is installed it rewrites the modem file, I think you'd be better off installing via newflasher as you could just remove the modem.sin from the install.
[Sony Xperia 5 III] Yeme:
Thank you so much Brentree I just updated this guide, removing the modem files from the firmware folder worked!
[Sony Xperia 5 III] Yeme:
I didn't check, but try to install Shizuku and Pixel IMS again, tell us if you were able to recover the Volte Options.
[Sony Xperia 5 III] Cristian.cojocariu:
Shizuku and Pixel IMS got the options to appear in settings and volte provisioning on in Testing/phone information menu, it's just the IMS registration that won't go through.

I had no doubt about Shizuku and Pixel IMS, since i tried them before doing the procedure described here.

I will do the steps again and by the next update try installing via newflaser as bentree suggested
[Sony Xperia 5 III] Cristian.cojocariu:
Ok guys, just done it again, works again!

BTW, the pixel IMS app is updated, and here is the link to the apk
[Sony Xperia 5 III] shoaib130088:
Jio 5G and volte WiFi calling work fine in India
[Sony Xperia 5 III] dima_vy:
I did everything according to the guide, no errors appeard, in the end i see in the menu that volte is provisioned, but when i make a call the network drops to 3G :( Any ideas? VoWifi doesn't work also... I checked my simcard in samsubg, and it works, volte and also vowifi, so it shouldn't be operator issue... Any ideas?
[Sony Xperia 5 III] Yeme:
@dima_vy Try to flash another MBN file, test all the compatibles in your area. Until you find one compatible with your carrier.
[Sony Xperia 5 III] dima_vy:
I know who is my operator, and there is an mbn file for the operator, also it shows the volte is provisioned... Do you still think that it may be the problem of mbn file?

And if i'd like to test anothe file, should i perform the whole procedure again?
[Sony Xperia 5 III] Yeme:
Don't relock your bootloader until you get volte and vowifi, if you did, perform the whole process again, and test other mbn files.
[Sony Xperia 5 III] dima_vy:
Yep, i already locked it... Vowifi should also work once mbn file updated?

Thank you
[Sony Xperia 5 III] dima_vy:
Tried several mbn files, and now, in first step where volte should work, i don't get it working :( May be it was same way when i tried first time... My carier is 012 mobile in Israel, it's running on Partner's network (one of the biggest local carriers)... Any ideas will be much appriciated
[Sony Xperia 5 III] Yeme:
Have you restarted everytime you flashed a new MBN file?
[Sony Xperia 5 III] dima_vy:
yes, i did
[Sony Xperia 5 III] dima_vy:
Anybody, any thoughts?

Thank you guys
[Sony Xperia 5 III] Cristian.cojocariu:
So guys, not so happy days...

Yesterday I was prompted for an update to 61.2.a.0.410, so I decided to do an install via newflasher.

I deleted all .ta files, i deleted all user data .sin so data wouldn't be wiped, and I also went and deleted all three modem related .sin files. Flashing went on ok, but..

Unfortunately the IMS registration won't go through even after multiple attempts with Shizuku and PixelIMS.

Any ideas for future updates?
[Sony Xperia 5 III] shoaib130088:
61.2.A.0.410 update successfully and volte wifi calling and

5G work fine Thanks @Yeme
[Sony Xperia 5 III] bentree:
Hmm, that's not the way to do it. All you needed was to remove just modem.sin and choose option (when prompted) on newflasher to keep user data.

Can't 100% say for sure that what you did broke IMS and VOLTE but I'm 99% positive it is what caused it. I honestly can't offer any other steps, other than to start at the beginning and go through the bootloader unlock all again.
[Sony Xperia 5 III] Cristian.cojocariu:
Okay, I will do so, and I will keep in mind what you said here by the time the next update comes by.
[Sony Xperia 5 III] myarnav:
@shoaib130088 please share which mbn file you used from above folder call mbn rar
[Sony Xperia 5 III] Cristian.cojocariu:
Tons of thanks to @bentree , i did the newflaser right this time, and it works!
[Sony Xperia 5 III] ralf_waldo:
@Yeme I'm not able to get past below step. those 3 xperia drivers are not showing up. please check image below and can you help to fix it.
[Sony Xperia 5 III] Yeme:
Which device? Have you downloaded Xperia Drivers from the Sony website?
[Sony Xperia 5 III] ralf_waldo:
Device is XQ-CT54 - Sony Xperia 1 IV. I have downloaded the drivers from sony website but dont know to install it on windows 11. Can I post message you @Yeme for further help!
[Sony Xperia 5 III] Yeme:
I can't help you man, this guide is only for Xperia III's devices
[Sony Xperia 5 III] ralf_waldo:
Okay. Just let me know if these drivers are installed correctly.
[Sony Xperia 5 III] Yeme:
Yep, they are installed correctly, you nailed it!. Congrats.
[Sony Xperia 5 III] ralf_waldo:
Thank you @Yeme .

Now, I checked in QPST but LAHAINA not showing up in active phones. any idea what could be the reason.
[Sony Xperia 5 III] Yeme:
I think LAHAINA is only for Xperia III's, check with EFS Explorer the device HW_DSDS_LA and see if the folders policyman and modem appear. If they appear, continue with the guide as normal.
[Sony Xperia 5 III] ralf_waldo:
Hi @Yeme I check HW_DSDS_LA and found some files as below in screenshot. Was able to find policyman. Should I go ahead and continue to add mbn profile?.

[Sony Xperia 5 III] ralf_waldo:
hi @anmolkakkar I'm using Sony 1 IV - XQ-CT54 version. Its supports Jio Volte and Wifi calling on android 13. Phone has one physical sim and one e-sim unlike HK/TW versions having both physical sims. Airtel is supporting only volte out of the box without any bootloader unlock changes. I searched the root folder using root explorer. was able to find only Reliance MBN. Airtel MBN is not present and is shown as ROW_Commercial in service engg mode.

I'm attaching jio MBN for everyones use. Please see if it works.

I'm unable to get Jio 5G working by replacing the carrier_policy.xml. QPST tool is not allowing me to replace the XML file. Not sure whats causing the issue. can you help here. please check screenshot below.
[Sony Xperia 5 III] ralf_waldo:
I'm using XML file provided by @Yeme in Mark III Thread.

Hi @Yeme can you help to resolve the drag/drop issue of carrier_policy.xml in QPST tool. I'm getting red mark while attempting to replace the xml.
[Sony Xperia 5 III] bentree:
Glad to be of assistance.
[Sony Xperia 5 III] anmolkakkar:
Thanks for the MBN zip. I need to make the 5G work. Jio 4G VoLTE and VoWifi is working fine for now.

Can you point to the thread where the carrier_policy.xml is exactly shared?

[Sony Xperia 5 III] anmolkakkar:
all in all, to make Jio 5G work, we need to load the Reliance mbn file (as shared by @ralf_waldo) above through that highlighted process and then copy this

carrier policy file into the policyman folder. And reboot.

This should make the 5G work, correct? @shoaib130088 @ralf_waldo?
[Sony Xperia 5 III] shoaib130088:
Yes
[Sony Xperia 5 III] anmolkakkar:
Just sharing an update that this didn't work for me in Xperia 5 III

Jio 5G still didn't work with this combination.

[Sony Xperia 5 III] jay.guy2006:
thanks bro
[Sony Xperia 5 III] anmolkakkar:
Will wait for your input @jay.guy2006. If this works, do share the Jio mbn file also that worked for you. Fingers-crossed.
[Sony Xperia 5 III] ralf_waldo:
It didnt work for me either on Xperia 1 IV to enable 5G. the carrier policy resets itself somehow after reboot and when sim is pulled while the device is ON.
[Sony Xperia 5 III] anmolkakkar:
Then most likely the steps mentioned in the OP should work for you as well. Just find the appropriate MBN file for your carrier and hopefully it should work.
[Sony Xperia 5 III] anmolkakkar:
ahh bummer!!
[Sony Xperia 5 III] Yeme:
Don't remove the sim and insert another carrier SIM, this will remove your IMS registration and you will need to perform the whole process again.
[Sony Xperia 5 III] mhys33:
So that's where I had a doubt. Where do you locate these MBN files that are appropriate for this? I have a oneplus nord that has vowifi and volte working, so source it from oneplus firmware? And will this guide work for 5 ii?
[Sony Xperia 5 III] anmolkakkar:
If you are on A13 on 5 II, the procedure should most likely work. Only you can verify if the steps mentioned in this guide actually work for you. :)

On the part about obtaining the MBN, there are many links to MBN zip files within this thread that can give you the carrier's MBN you are looking for. e.g. if you are looking for Reliance Jio to work, download the mbn zip from within this thread and search for "Reliance" after extracting the multiple files/zips from within that. Load that .mbn file as guided in the steps and most likely it should work for you. You don't need to use any other phone to extract it's MBN file, the files are already attached in previous posts.

Hope this helps.
[Sony Xperia 5 III] mhys33:
Quick update: I got volte working simply by flashing modem and OEM from SEA (AS72) firmware. Vowifi is still non- functional though, I'm on vodafone India. Maybe I'll look for a specific MBN to get this up and running.
[Sony Xperia 5 III] anmolkakkar:
Did you try the Shizutsu method in stock? Maybe that makes it work.
[Sony Xperia 5 III] mhys33:
Shizuku didn't really make any difference, I'm on vodafone India and they do offer Vowifi AFAIK. So maybe MBN is what I have to use. I was also thinking I'll try with an airtel SIM as those have both vowifi and volte working on other phones in the house.
[Sony Xperia 5 III] mhys33:
Another thing I wanted to ask is, does flashing the stock ROM restore the original MBN that came along with the device? Just wanted to know if in case I wanted to revert any changes.
[Sony Xperia 5 III] anmolkakkar:
Yes it should as it flashes all the partitions (that includes the modem bin files too).
[Sony Xperia 5 III] sammyljk:
I had to use this command to get it to switch modes correctly, but I'm on a crdroid rom.

[Sony Xperia 5 III] faseeh_55:
In order to make 5G work on your Xperia device with the Jio SIM, pls follow the guide listed in the OP. When you have set everything up after the phone restarts, go to Settings→Network and Internet→SIMs→Access Point Names→Click on 'Reliance Jio'→Go to the very end of the list to 'Bearer' and put a check on 'Unspecified'.

This will allow you to use 5G internet.

I'm successfully using full capability of Jio True5G on my Xperia 5 iv (XQ-CQ72) by following this guide, thanks to the OP.

Hope this helps.
[Sony Xperia 5 III] Cristian.cojocariu:
Ok, so new fw updateand unfortunately new problems.

I did the same things as before, it all worked, but the camera wouldn't stop clicking, and it threw up an error.

Tried clearing cahche, data, rebooting to safe mode and finally factory reset, and nothing worked.

Then I flashed the entire fw again using the modem files too, and it all works fine.

I was so worried that it would grow to be a hardware issue, but it isn't!

Since now I have a fresh install again I will try this:

and then report back.
[Sony Xperia 5 III] shoaib130088:
Yes I am same problem
[Sony Xperia 5 III] Cristian.cojocariu:
Yep, the options appear after PixelIMS, but for my Romanian carrier no success with IMS Registration

[Sony Xperia 5 III] Dallan Invictus:
I had the same camera problem after trying to flash the July update without the modem files, unfortunately.

edit: but after flashing the whole stock update and then redoing the whole process in the OP it was fine
[Sony Xperia 5 III] SS_X1:
Hello, I have a Xperia 1 mark ii Japanese au variant (SOG01). I want to enable volte and vowifi on my Airtel sim as well as 5G if possible.

So far I have tried a different method where I have used xperiferm to download stock rom for SOG01, and replaced boot, modem, and OEM files with the SEA XQ-AT52 firmware.

This resulted in volte working and removal of au bloat, but vowifi (wifi calling) doesn't work.

I'd like to know if the method shown here would also work for this phone (SOG01).

I'm reluctant to try out this method because I've heard that unlocking the bootloader and patching the boot.img with magisk and flashing then could result in the TA partition being erased from your phone resulting in the loss of the DRM keys.

Has anyone tried this method in 1 mark ii? If so I'd like to hear if you got it to boot and got volte and vowifi working.
[Sony Xperia 5 III] sumitplall:
Hi folks, I am stuck in the very basic step itself. Can someone help me?

Download QPST from https://qpsttool.com/ and install, also, you can find the Qualcomm Drivers inside the zip, install them.

After that, it should show up 3 Xperia on the device manager and install one by one manually using Qualcomm driver just youtube this part. Use Qualcomm USB diagnostic 9091 or 9081.

I see 3 Xperia devices but not able to install drivers for it and don't see the COM & LPT ports in the device manager as well. Which drivers do I have to install after this step?
[Sony Xperia 5 III] Mikuso27:
after following this guide I got

DCNR Restricted : True

NR Available : True

NR State : RESTRICTED

Any Idea?

*before following this guide I already flash modem global and working VoLTE but not 5G without root.

*after following this guide I got that true state but NR State : RESTRICTED.
[Sony Xperia 5 III] bentree:
Most likely your provider isn't allowing your phone to connect to 5g services.
[Sony Xperia 5 III] Mikuso27:
Ok, good to know then I try ask my ISP.
[Sony Xperia 5 III] SS_X1:
I have the same phone, 1 ii au kddi (SOG01)

How did you get the bootloader unlock status to change from no to yes?

Are your DRM keys fine after unlocking and doing the magisk flashing process?

Can you tell me how you did this?
[Sony Xperia 5 III] Mikuso27:
need paid tool to change to Yes. ofc I lost DRM, if you need DRM back just unroot and lock the bootloader back. for flashing magisk i following this guide. working fine using latest magisk version.
[Sony Xperia 5 III] SS_X1:
Oh I see, after unlocking the bootloader once can you relock it back again?
[Sony Xperia 5 III] Mikuso27:
Yes
[Sony Xperia 5 III] SS_X1:
Thanks for the reply!
