any idea?

This is with the almost (at least I think so) whole ril stack from the vendor which doesn't produce any other errors.

I followed the idea of the mt7l09 dev who impleted a RIL class which is used in the P8 lite version as well. It seems that these three devices share the same modem (viacbp82d).
