While attempting to switch to CM11 I tried upgrading TWRP from 2.4.4 to the newest 2.6+ and it messed up my recovery. Then, while trying to re-flash an older TWRP, I accidentally installed SuperSU over an existing install, and lost root. Tried re-rooting the device using motochopper and it gets to the last part, "rooting device" and it says "failed". Device the reboots, I try to open SuperSU and it says "no SU binary installed". All I'm trying to do is put back TWRP 4.2.2 so I can restore my device. Please help

EDIT: Tried using fastboot to install image, everything looks good, then my tablet freezes up. I do a power cycle, it reboots, and the recovery didn't flash.

UPDATE: Recovery flashed and wiped EVERYTHING. I am back on recovery 4.2.2.0 but nothing is mounted and I can't mount anything, I can't make backups or restore images, and ADB Sideload does not work. Any help would be really, really awesome. I have SDK Manager, and I can currently use ADB on my computer, I just don't know what commands, blobs, or images to use.

Can you use fastboot to reflash the stock ROM?
