I'm trying to install Nethunter on a Samsung Nexus 10. I've gone through all the steps on the NRT to unlock and root. I've installed TWRP Manager and Busy Box with permissions granted, but I get an error when trying to flash and verify recovery in TWRP. I'm trying to install version twrp-3.0.2-0.manta.img. I've tried to push the nethunter.zip through the NRT and it looks like it's supposed to on the videos/forums but once everything is checked and installed it reboots to the google home screen. What am I doing wrong?
