I bought the Japanese model (the SOV40 from KDDI AU) and it doesn't support VoLTE.
Then I flashed the J8110's Customized UK firmware, ended up still not having VoLTE.

The last thing I did was following this method and it worked!
I now have VoLTE working properly! Could receive/make calls coming to/from my number.

Based on my own testing (on the SOV40 device), this method worked on J8110's Customized UK firmware (based on Android 11) and SOV40's own stock firmware (based on Android 10).

As these "patch files" are copied from the Customized SEA firmware for J9110, it may/may not work for other region (due to maybe the SEA firmware only have VoLTE profile/support for SEA countries). Meaning you might have to find other firmware that have support for VoLTE for that region.
You can still give it a try, if you want. You can download the "patch file" from my reply in here and flash it with newflasher.

I'm using 802SO too. But the NFC work?? (Because I need using NFC for something, but your files ROM base on global version, so the NFC function??)

Sorry, I lost your message...
In the #1 --> "NFC And All Other is working."
Thanks a lot~
I'll try to test the firmware, but I haven't flash ROM code for a long time.
Let me study some information & flash it to test...

I'd flash ROM code, and work fine about all... Thanks!!
But NFC still not work.
I pair with my BT ear phone & smart watch, all can't work.
And then using "NFC Tools" to read NFC tag, still not work (can't read any tag's UID).
Have you any idea??
If not, I'll flash back to 802SO official ROM these days...

 

[Johnyxda]

Everybody don't try it~ (except you don't need NFC)
The NFC function lost forever..........
I'd downgrade to Android 9 & 10, newflasher 802SO official ROM, but NFC still lost~ ...v_v...
