[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] blopido:
Hello everyone,

So I got bored of my Kindle Fire HD 8.9" 's limitations and decided to root it and install a second bootloader. The rooting went along just fine (used bin4ry's method). Even as I tried installing a second bootloader, everything seemed to go normally.

I used [MENTION=4243514]Hashcode[/MENTION] 's method from this thread: http://xdaforums.com/showthread.php?t=2128175

However, after Step 5 (when I should have got a blue Kindle Fire logo), the device got bricked. No screen, no nothing. I can't even hard reset (tried holding power done for 20 seconds, 30 seconds, 300 seconds) or get it to connect to my computer to fastboot / adb / anything.

The worst part is that I cannot even use a factory cable now, because the 8.9" doesn't support it for resetting. The device was almost fully charged to begin with and I recharged it once more overnight just to be sure.

Did I do anything wrong? Any ideas?

Here's what happened:
