FYI, i'm pretty sure TWRP 2.7 (official from GooManager/TWRP site) doesn't work. if you click on the console button (square with lines in it, top) it'll say "This kernel doesn't support configuring SELinux" or something like that. i tried wiping stuff and it would just do a soft reboot. i may go file a proper report to TeamWin but i have CWM on there now and i don't particularly feel like reflashing a broken recovery.
TL;DR don't use TWRP
