Can't get any computer or OS to recognize my kindle fire HD 7 even with the factory cable. Help!!!

I was in fastboot mode and did a reboot and when it booted back up it stuck on the start screen and won't let me do anything anymore. The fastboot cable I bought doesn't put it into fastboot mode and it is not recognized by any of my computers or OS. Tried everything but my mac so far. That includes XP, 7, 8 and Ubuntu.


I'll try a hard reset again. I've done that several times hoping that one time it would get recognized by the computer.

Re: [Q] Kindle fire HD 7 hard bricked????
Before you panic too much, you need give more information. What were you doing to "brick it"?

Have you tried a hard reset btw? (Hold the power button down for 30 seconds) then let go and turn on?

Worked for me before when I thought messed up

You were doing something in fastboot mode, What was it? did you try to install the 2nd bootloader by hashcode or just restoring your device?

I did something similar and have what i though 'bricked' the kindle. Have another good read through hashcode 2nd bootloader thread, others have has similar, and there are some instructions on how to resolve fastboot cable not recognised, and kndle is bricked. if not, go down the firstaide thread, that also deals with bricked kindles.

good luck

I just had same problem. Factory cable no use. I intalled Kinology but thought to restore to a Kindle version. When the bootloader was being flashed, a black brick ... Anyone knows how to deal with this? I even opened the case and unplug battery.

You all have a paperweight on your hands. The factory cable was the very last resort. If you're in warranty, send it in for a replacement.

A while back, I brought this question up to Pokey9000, the developer of FireFireFire and Firekit for the Original Kindle Fire. His exact response to me was...
Quote:

When the OMAP USB boots, it first waits a bit to handshake with a host. If the handshake is successful, the host sends a small loader to the OMAP that then does some hardware init and handshakes again with the host to get a payload to shove into RAM. This loader is similar to x-loader in that it has to be small to fit in the SRAM of the OMAP, and does low level initialization like mux, clock, and memory setup. However it differs in that it replaces the MMC and FAT handling in x-loader with USB loading as there's not enough room for a generic x-loader that does MMC and USB.

On HS (fused) OMAPs this initial USB loader payload must be signed just like x-loader has to be for eMMC boot. If the payload doesn't have a signature that checks out, the OMAP halts until it's reset. This is enforced by hardware, so short of finding a sploit in the OMAP ROM code or a copy of Amazon's USB boot tools used in factory it's not going to work.

TL;DR not likely.

Considering his knowledge of bootloaders and low level hardware stuffs far exceeds mine, and the fact that he's been looking at this issue ever since the B&N Nook devices (maybe even longer), I have to assume he knows what he's talking about.

The information on the page at Mascote seems to contradict what Pokey9000 says because usbboot uses an a-boot(x-loader) instead of this not-so-typical USB loader mentioned previously. And the answer to whether or not the author was actually successful in reviving the KFHD using this method has been left a little ambiguous.

But, as much as it would suck for me to have been the d*ck that told everyone that it couldn't be done, I would LOVE to be proven wrong.


I'd say, if you have a hard-bricked KFHD, then I guess there's not much else you can lose by testing it out.
