Problem: CM won’t load (infinite startup animation, bootloop) after the upgrade / flashing the XPosed.
Solution: Since the latest November security patch the XPosed does not work, wait for the official XPosed update.
Problem: Something else stopped or not working!
Solution: Try to update your device to the latest CM13 build or downgrade to the previous version. Also try to format “system” partition. Then you need to install Gapps right after CM installation. This way all your settings and applications will remain.
