Now the issue is fixed. Cause of it is due to old baseband with newer RILD incompatible.

MeizuE3 baseband ver: MPSS.AT.2.3.c8-00068-660_GEN_PACK-1.147274.0.158539.1

and the based rom is by S.AT.3.1-00815-SDM660_GEN_PACK-1,S.AT.3.1-00815-SDM660_GEN_PACK-1

the core problem is rild vs qcrild choice, where rild is the old passthrough API and the qcrild for newer VNDK binderized API. there are still some problem related to old FW and newer QCRILD blob

A more elegant solution need to address out.
