Hey,
I was using CM13 (september nightly updated), and was not aware that cyanogen had shut down, so recently updated to CM14.1-20161225-NIGHTLY. Phone started going haywire(google and other apps not working). Came through this article and tried flashing CM14 and Gapps. Tried Gapps(super,pico,aroma), but still whenever i reboot i get the following on my screen – com.android.phone stopped working. Google apps not working. I cant even downgrade or upgrade to cm13 or cm14.1 , Any suggestions what should i do to recover my phone??
