How to Enable Volte and 5G Without Permanent Root on Xperia 5 III and 1 III

First of all, Thanks to @johndaniel, @htcmage, @gorEisberg @Forbesii @morphvale @arjun_m4 for sharing all the information and files required for this guide. FIRST THING FIRST: Data is priceless. Always backup before you modify your phone...

Unfortunately that doesn't work for me. The way Sony has locked down my device in my region is rather complicated. It's rather annoying.

I have the same problem. I've tried all the guides, the only thing that worked for me was manually editing build.prop, that was an absolute nightmare to do and still haven't quite worked out how I managed to do that.

Only other option was to use magisk which I've reverted back to as the 30 volume steps has been great for me while in bed.

Yeah it's great when you have 30seconds spare and you are in a rush.
Another file worth looking at tho (and is loaded before all the other xml files) is "mcfg_sel_db.xml". I think it's what sets the limits for certain areas.
I have attached the one that is loaded for TW region firmware. Each region firmware has different xml file.
Cheers, Ben.

We might need to wait for TWRP to be fully compatible with A13 so we can manually edit build.prop from TWRP or ADB.
If we don't want to use magisk that is

The build.prop edits are what we're missing on our regional phones for VoLTE & VoWifi. The mbn files can only do so much, if it's not enabled in the build.prop then it's not possible to use

5g works fine with the mbn file though.

As the title states. I have been deep diving into my 1III modem files and have found (what I think) is a file that has something to do with what operators are allowed to use VOLTE and VOWIFI.

How ever try as I might, I can't open this file. It is not Microsoft Database File or if it is it's highly modified from its original form.

Just wondering if anyone out there new how to open it? I have attached the file (as a zip) so that maybe someone smarter than me can maybe work it out.

Cheers, Bentree.

works for sony

Yeah no, it works for some operators but you need to still modify modem files with EFS tools and that all requires root access.
