So here's what happened:
I got my root from rootkindlefire.com and followed the necessary steps (i'm running on 6.3.1)
It got halfway through and froze and I stupidly unplugged my kindle
Then it was stuck on this screen with a yellow triangle with a flame in it and at the bottom is said press power button for recovery, but when I pressed it nothing happened
So I went messing around online, in my drivers, etc. I ended up deleting my kindle drivers (like the original ones) and now my kindle is freaking out.
I watched this other tutorial on rootkindlefire.com and tried to follow the steps on how to unbrick it but when I managed to get into the recovery (i can't remember what it's called? blue screen with options like install, mount, reboot, etc.) and put the zip drive he said to, in there... i couldn't see it.
I then downloaded KFU and managed to get my kindle to reboot, but it is now stuck on the "Kindle Fire" screen. I can turn it off, get into recovery, etc. I cannot get it to move past the start up screen however.
I do not believe I am in fastboot, but one of the sites I was on could have misled me. Anyway... HELP! please... I'm sad:/
