Not sure about the kindle HD, but an Original Kindle Fire 1st gen, will boot direct to fastboot mode, when connected to a Fastboot cable
Both require Hardware cable and device to be working correctly.
According to the description on the amazon site that I bought this cable from it shows the cable as being able to support Kindle Fire HD, that is why I am thinking that this cable is faulty, since it is not working on my droid nor is it working on my Kindle Fire.
I am thinking on buying a different one and returning my current one but i'm hesitant to do so. I have my doubts that this will allow my Droid 4 to boot up and/or be recognized by my computer. Since I get no response with the Vol-, Vol+, Power button combinations i'm thinking this is hard bricked because of the wrong files I flashed to it.
Before I made this mistake the phone was at least responsive showing the android/exclamation point screen. Then my dumbass ran the wrong flashing utility and that was all she wrote.
Do you think there is hope for my my phone even though the power button yields no response? If the fastboot cable will at least allow my phone to be recognized by my computer then I think i could save it, but that is where i have my doubts, but would love to try.
