Trying to restore after wipe, but ADB is not enabled
I unlocked, and rooted my nexus 7 using the Nexus Root Toolkit.
Everything was good until, after a few days, I tried turning on my device but got stuck on the "X" loading screen. After googling for a bit, I figured a factory reset would do the trick. I tried to factory reset the device in TWRP, but was confused by the two buttons and accidentally wiped everything (in adv wipe with everything checked).
Now the next problem is that I don't have USB debugging enabled (I recall turning it off for some reason). When i run "adb devices", nothing comes up and so i can't push anything to the device (and everything is wiped). Is there a command i can run, or file i can edit while in TWRP recovery mode to enable it? It seems i can't do anything without it enabled.
