Hi.
I've been running NetHunter 1.1 on Nexus 7 (2013) WiFi for a couple of months.
I wondered if it's possible to download NetHunter 2.0 ZIP image and install it over my old installation in recovery mode.
I tried and remembered to wipe Dalvik + Cache, but it stuck in the four circles.

I tried to wipe System + Data + Dalvik + Cache and reinstall NetHunter ZIP image, and it hanged on Google + unlocked locker.

Any hints? Thanks!
