After a lot of try and error i managed to get some success with the driver files and their included documentation. However I’m still facing a few issues:
For RIL 1.1:
The manifest XML provided in the documentation seems to be incomplete as i needed to add some extra bits from here:
Without the extra XML bits i always got this error:

Other than that it looks like its working for the most part except for audio during voice calls.
Is there some extra configuration required to get that working as well or does that have to do with the RIL driver being incompatible with android 13 ?
GPS is working as expected too so thats something.
So far i wasn’t able to test the data connection yet. I’ll check that later.
For RIL 1.6:
It doesn’t even manage to start the rild due to some linker errors due to a missing symbol. No idea where to start debugging that as i suspect that its related the ril library you provided and not anything with the android itself.
