2.0 & 3.0 hobbled on Nexus 7 2013 (flo)

[Kaolinite]

Edit: The problem with seg faults might have been caused by choosing the option to install SuperSU 2.67 from the Kali installer, with SuperSU 2.52b it is working.

Tablet specs:

Product Name - flo
Variant - flo 16G
HW Version - rev_e
Bootloader Version - FLO-04.05
Carrier info - None
Signing - yes
Secure boot - enabled
Lock State - unlocked

Tablet was flashed with 5.1.1 LMY48T from Google, TWRP (a custom build for this hardware version), and SuperSU 2.52.

Both NetHunter 2.0 and 3.0 install without errors. 2.0 doesn't install its kernel, others have reported this problem here and here. 3.0 does install the kernel, but none of the services will run.

#service --status-all

This returns seg faults after every listed service. apt-get update && apt-get upgrade have been run.

2.0 might work if I could find a kernel to install with the right drivers. I have no idea what is wrong with 3.0. Any guidance would be welcome.
