So I run the script as suggested on the Wiki/Github, followed all the links to get the NetHunter file(nethunter-grouper-lollipop-3.0.zip) Google Nexus Stock Image(nakasi-jzo54k-factory-25cab35c.zip), the TWRP Image(twrp-3.1.1-0-grouper.img), as well the SuperSU file(BETA-SuperSU-v2.66-20160103015024.zip), place them where it says to in the nethunter-LRT file cloned from Github.
I boot into the Recovery(I already had it rooted before so it has TWRP on it, then I run the twrpFlash.sh file, it runs through fine pushes the .zip to it, reboot into the Bootloader, then it says "Flashing TWRP image < waiting for any device >" http://i.imgur.com/QcqVmBk.png
Doesn't get past there at all. Did I make a wrong step somewhere or?
