[Q] Kindle Fire HD 7" Freezes on Fastboot logo

---

In trying to install a custom bootloader on my Kindle Fire HD 7", I bricked it. When trying to start it normally, it shows "kindle fire" for a few seconds, but then the screen goes black and it becomes totally unresponsive. When I tried booting it with a factory cable, it shows "kindle fire" for a few seconds, and then switches to the "fastboot" logo, but again it is unresponsive. In both cases, my kindle is never found by adb or fastboot or any other utility when connected to my computer. I'm fairly certain this not a driver problem, because my kindle was recognized before, which is how I rooted my kindle. Is there anything else I can try to unbrick my kindle? The main problem is that it is never recognized by my computer. Now what?

What custom bootloader did you try to install?

EEK!!!!

Messing with the bootloader on the kfhd is suicide. You may want to think about calling Amazon and see if they will replace it.

Go into fastboot mode and type this in command prompt wherever you have fastboot.exe and adb.exe (To do that just go to that folder, shift+right click anywhere and select open command window here).

Post the output

fastboot -i 0x1949 getvar product

and idk if you know this but...if you get your kindle into fastboot mode... all you see is the logo nothing more, and everything else is done through command prompt in windows, So assuming you already know that, what made you think it is unresponsive?

Yeah he is right. Call them, tell them what happened but not how it happened.

The issue is that my kindle is not "discovered", "recognized", or whatever you want to call it by my computer. It has before, because I was able to root my kindle earlier, so I'm fairly certain that it isn't a driver problem, which is the usual response I've found. None of the fastboot commands work because my kindle can't be found.

Hmmm.. Thats weird what did you exactly do? I would try to reinstall the drivers. When you go into device manager do you see it there when it is plugged in? I had the same problem but my micro usb ports where fried in the Kindle bc I had a faulty fastboot cable.. Let us know if you see it in device manager..

If you tried to install Hashcode's 2nd bootloader, which is the only one that would work, it sounds like you missed a step somewhere. Is that the bootloader you tried to install?

Alright, so it was a driver problem. I ended up removing all drivers and sdk stuff, and then reinstalled and reloaded everything, which enabled fastboot to discover my device when using a factory cable. Problem solved. I found you just have to be careful when setting up sdk, and do every single step as listed on https://developer.amazon.com/sdk/fire/setup.html.
