This property completely stablized the RIL for me. Now, keep in mind that I only have one sim. For dual sim situations you may need to remove this from the build.prop or change it to something like persist.radio.multisim.config=dual . I suspect that it will, by default enable both modems by default by just removing the property...
Also some of the sensors have been fix thanks to surdu_petru@xda. I have not tested them all but the accellerometer/orientation sensor and the proximity sensor are working.
The installation instructions have changed please read them carefully!
