[problem] installing nethunter on NEXUS 10

hi all!
i request your help to find a solution to my nethunter installation failure.

i'm under nexus 10, Android 4.4.2, mantaray - Kot49h, unlocked, rooted.

I go into my recovery (CWM v6.0.4.7), i click on install zip from sdcard.
I select, after, my archive "kali linux nethunter 2.0 mantaray kitkat" from the tablet internal memory.
The installation start...
and after some time installation is aborted with the following log:
