I recently got my hands on a kindle fire HD 3rd gen tablet and wanted to root it because the amazon OS is terrible. unfortunately i could not find any guides on how to root this specific tablet (i tried rooting my first kindle fire but TWRP didn't install correctly and it is now bricked.) I want to be careful rooting the tablet this time around so any suggestions on where to get started would be greatly appreciated! right now i cannot seem to get it recognized by my pc, i am not sure if it is a cable problem in not but it shows up as unknown device in my device manager tab. I am a newcomer to rooting so again any suggestions would be great. Thanks!
