Default [Q] BIg Trouble In Need Of Help!!!

Okay so all I wanted to do was to just root my phone and have android 4.1.2 and sense 5 software on my HTC One while having the keyboard of sense 5.5 since I want to keep its emojis.

But I've hit a dead end and somehow along the way now I have no OS system running and I'm stuck on TWRP recovery mode. I honestly don't know what to do.

Somebody please help!! Reply ASAP!!
