So, a few days ago I managed to root my kindle fire 1st generation. I've been playing around with it, and noticed that it was rather slow. I thought about trying a different ROM for it to see if it would run any faster. Not entirely thinking, I didn't make a recovery with TWRP before I did a wipe. And now I have a kindle with no OS, and it can't flash anything because it doesn't have a root anymore.

I've been hunting down information on what to do for six-ish hours so far, but I haven't had any luck with anything. Can anyone help me?
