Progress so far:

• Installed TWRP, LineageOS, Magisk successfully
• Attempted to install imsservice.apk from this repo, got error adb: failed to install imsservice.apk: Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE: Reconciliation failed...: Reconcile failed: Package com.sec.imsservice has no signatures that match those in shared user android.uid.system; ignoring!]
• Decompiled imsservice.apk with apktool
• removed android:sharedUserId="android.uid.system" from AndroidManifest.xml
• Recompiled with apktool
• Signed with signapk using AOSP Stock keys
• Tried installing, got error adb: failed to install imsservice_signed.apk: Failure [INSTALL_FAILED_MISSING_SHARED_LIBRARY: Reconciliation failed...: Reconcile failed: Package com.sec.imsservice requires unavailable shared library imsmanager; failing!]
• Removed <uses-library android:name="imsmanager"/> from AndroidManifest.xml
• Recompiled, signed and installed OK, but VoLTE still not working

I figure I need to:

• Locate correct imsservice.apk from the stock ROM for my device, and try again with that
• Maybe try older LineageOS/Android version

I downloaded my stock ROM with Frija, converted with simg2img and was able to mount the img and access the stock imsservice.apk and decompile it

Unfortunately the smali file/folder structure is different, there is no cmcnsd folder or NsdNetwork.smali so I can't apply the patch
