Any 64 bit Rom (VOLTE Enabled) stable for this phone

I am thinking to change my existing rom and move to more stable 64 bit rom. Any help devs?
almost all the roms have working VoLTE, I would suggest you to try pixel experience first.
And make sure while rolling back to stock rom you need to deprecate modem1 and modem2 files. Otherwise you'll lose imei as well VoLTE forever
Actually I'm non US variant and Volte stopped working on most of the latest Roms ( BL, RR, Xtended) but DU works fine. I also recently re-flashed back to stock firmware and Volte is fine....something is off with these latest ROM builds ( atleast for me).

T-Mobile Volte & WiFi Calling on custom ROMs?

Running Phh-treble (Android 9 Pie stock based ROM) on my T-Mobile Moto E5 plus (Hannah) and it's great. But I had T-Mobile WiFi calling and Volte on stock ROM, and they don't work on Phh-treble.
Is there any way to get T-mobile WiFi calling and Volte working on Phh-treble? Or on any other custom ROMs (lineage os, etc.)?
I've searched around and done quite a bit of reading, maybe WiFi calling and Volte can be enabled by pulling some system/priv-app(s) from the stock rom and integrating them into the custom ROM system? Not sure which one(s) would have the carrier configurations though. Anyone have any ideas?
Thanks!
I believe I read in one of the threads there was a magisk module that did it.
But I can't seem to find the thread now.
Check the magisk module " VoEnabler". Although they say it needs work, like nobody has had any success so far.

Modifying mbn files with AOSP rom

Hello,
I was wondering if there is a way to modify mbn file to allow for vowifi with carriers that dont provide it. I followed the following post to allow my mi 9 running miui 12 to work with vowifi https://community.oneplus.com/thread?id=1284987 I am looking to update to an android 12 aosp rom but I am unable to use the same procedure since there is no diag port on aosp rom. Is there a workaround for this ? Another procedure or a way to enable diag port ? this is my last hope before giving up on this since I tried almost everything and I cant find posts on xda that talk about this. Thank you.

Which ROM do you use?
Please try official PixelOS (recommended) or Lineage Beta by SebaUbuntu.
These are the only AOSP ROMs with working VoWifi. (at least in my case)

I tried all the MI9 available roms android 12 and pixel experience for android 11. sadly I cant get vowifi to work with any of them. I get the volte working but not vowifi. It seems like I need to do the method in that link. Are you also using freedom mobile in Canada ?

Unfortunately opening diag port seems impossible on aosp.
I've tried every possible way to do it, as i had the same problem like you.
On MiUi, vowifi works for you?

Yeah it works but only after I write the mbn file using EfsTools. It sucks honestly that I am stuck with miui. I also tried everything but thought I would post here as a last hope maybe someone has a workaround to get it working.
