Error installing Xposed Framework
Based on the screenshot, there's an error saying cp: write error: no space left on device. It seems there's no space in /system partition of the device.



Flashing Xposed Framework would make use of the device's /system partition.

In case there are apps or anything bloating up the /system partition, try removing them and freeing some space from unused apps, and then re-flash it again with a recovery program like TWRP or ClockworkMod.

Before reflashing, do wipe the cache/Dalvik cache first. Whenever the errors appear after flashing, wipe the cache/Dalvik to be sure it's clean before flashing again.
