Hi, for those who don't know, the Chainfire app FlashFire (available from Play store) can successfully flash zips as one would normally do in a custom recovery. It's not quite as good as having an unlocked bootloader and TWRP, but it can handle stuff like TBO app and custom mod zips and such just fine.
I'm running 4.4.2 because I don't know how to root anything higher, so I can't speak for other versions of Android. But if you're on NC2 you're in luck. I've flashed many things with FlashFire and haven't had any issues yet.
