Nexus 7 (2012), Net hunter 2.0 kitkat, keeps on freezing/unresponsive

Hi guys,

Installed nethunter 2.0 Kitkat on my nexus 7 (2012). Works perfectly, no errors or anything :)

Its just one thing. My nexus keeps on being temporarily bricked every 3-4 hours or so.
It doesn't respond to any of the buttons - does not turn on nor make any sound.
But it doesn't seem to be OFF either - because the power button doesn't turn it on straight away. I have to press and hold the power button for about
10 - 15 seconds to make it 'reboot'. It works normally then. Until it bricks again after about 4 hours of not doing anything.

I'm waiting for it to go in that state again so I can try and see if i can connect to its ssh while in that state. I'll post the result when I do.

Are there anyone with the same issues? I cant seem to find any similar case in the forum. Apologies if there were any.

Any good sirs who can help me with this?

Thanks
