[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] drowsyhaze:
Hey folks! First, thanks for all of your hard work on this! I'm surprised at how active these forums are even with developers moving on to newer tablets - it's really impressive to have such an active community!

My problem:

Kindle won't boot; not recognized by ADB or FastBoot on multiple computers/OS's. Likely bad bootloader but can't push stock bootloader without ADB/FastBoot.

How I got there:

Alright, so, I recently received a Kindle HD 8.9" from a friend and tried to unroot it in Windows. I didn't get very far with multiple attempts and, eventually, got to a place where the adb labeled the device as "offline." After updating the SDK and adb, uninstalling and reinstalling drivers and so on, the Kindle was still listed as "offline." Tried different USB ports and so on, still offline, so I followed the "try a different computer" advice. Fed up and remembering how easy it was to unroot and mod my old Evo 4G in OS X, I decided to boot into OS X.

I quickly came across BreakDroid (KindleWater), which one thread or another suggested would work with the Kindle Fire HD 8.9". I started it up and got further than I had ever gotten before but with errors - the flash at the end of the "Step 1" script worked, but there were permissions error prior.

Stuck in fastboot, I turned off my Kindle and then decided to log-in as root and restart the process, thinking this would resolve any permissions issues, but my Kindle never turned back on. Now my Kindle will not turn on at all (even while holding down volume buttons) and is not recognized by 2 different macs and a windows pc. When issuing "sudo fastboot -i 0x1949 getvar product" I get "ERROR: Unable to create a plug-in (e00002be)" after some time. ADB shows nothing and no device drivers load in Windows.

So, a few questions:

First, Is there anyway to get my Kindle to boot? Looking into it a little, it appears (although is unclear) that BreakDroid is only for the 7". You can see the code attached below - is my phone bricked? I'm going to boot back into Windows and try KFFirstAide and "KFHD System.img Recovery Tool" and, if those don't work, try Ubuntu and SoupKit. I do have a system backup that was made with KFFirstAide. Any thoughts on how to get it up and running again? Although I'm not that fluent in the Windows environment I'm pretty savvy with Linux and OS X.

Second, if it is bricked and I have to send it back to Amazon what risks do I face? Is it likely they'll just send it back fixed and all will be well, or will they keep it and/or sue me for messing with the boot loader? Would I be better off sending it to someone who unbricks and roots Kindles to avoid additional frustration from a gift?

Any thoughts and help are greatly appreciated! Thanks!

P.S. Here is the code BreakDroid ran. I recall "file already exists" and "unable to copy" due to permissions errors but, unfortunately, I killed the terminal before copying the output thinking I could just log-in as root and redo the process (which I did not attempt). The flash at the end of the code, however, was successful (confirmed on Kindle's display).
