Your problem seems a lil vague to really help and it depends on if your computer is still detecting your Kindle Fire or if you drivers need installed. Also if you are using the one click program to root and install ur TWRP and rom simple connect your kindle to the computer and click the fast boot option and change it to normal. I did this when my fire was stuck in fastboot mode and would only boot loop. even though it wasn't detected by the one click program it was still changed to normal boot mode and i was then able to get into TWRP.
