[Xposed General] Thorge01:
I understand - then something else causes the problem. In this specific case it is hard to find the troublemaker. If logcat does not give the results to make out an error caused by any module i would do the following:

uninstall every module, after that Xposed. If that is done reboot into recovery and wipe dalvic cache and cache twice or three times. After that is done reboot normal and wait till system is fully loaded (this may take some time as you know). If system has finally startet reboot again into recovery. I highly recommend to upgrade to latest TWRP v.3.0.0 (choose the right TWRP Version for your device directly from TWRP homepage).

o.k., once in recovery flash xposed-v80-sdk23 (arm64 or x86 - depends on what cpu your device has) again and let it reboot (this may take some time as well). Once fully booted install the XposedInstaller_3.0_alpha4.apk and reboot. If rebooted go into Xposed Installer app / Framework and check if "Xposed framework version 80 is active" is standing on top of the page. If it`s there you`re good to go.
