Default [Q] No OS Installed, Can't Mount /data [Solved]

Okayyyy.... So, I was a bit foolish and when trying to install CM11, I wiped my internal storage. So now I don't have OS on my phone. Also, I cannot mount /data in TWRP 2.6.3.0. What to do next as there is no RUU available for Mini? ADB Sideload doesn't work either due to me not being able to mount /data. What do do now? :I
