Um can you elaborate if you are requesting the dual sim fix until the new build including init changes is released have you tried what I outlined in a previous comment?
I have had a quick look at other devcies and these properties may or may not help
ro.telephony.ril.config=simactivation
persist.radio.multisim.config=dsds
and maybe this one
persist.radio.dont_use_dsd=true
Adding these to build.prop has fixed the issue for other devices.
I am relying on
@Runner85sx to release zips currently and I'm mainly working on bug fixes.
