Default [Q] Safestrap not booting

I'm on the last knoxraid...and safestrap says it's installed but won't reboot from the app...and rebooting manually normal, or into recovery doesn't work. Actually rebooting recovery goes to stock recovery, and rebooting shows the Samsung screen, then seemingly turns off. I have to hold down the power button to boot it.

Any suggestions? Should I try the whole safestrap install from scratch?
