[Kindle Fire Q&A, Help & Troubleshooting] soupmagnet:
Make no mistake about it...I am sympathetic to every single person who "bricks" their device. However, I find it very hard to be sympathetic to those who fail to take personal responsibility for a problem they created due to not having done the appropriate amount of research before getting involved in something they didn't understand.

First off, your device does not have to be rooted to install FireFireFire. As a matter of fact, it's better that you install FireFireFire

before

trying to root...but your drivers

have to be in working order

from the start. And you have

absolutely NO RIGHT

to push blame on someone else just because you don't have the knowledge necessary to modify your device without tools made by other people. It is your device and your responsibility...so own up to it.

Second, I can say beyond all uncertainty that the information needed to understand and resolve yours and 90% of all other situations in this forum, can be found in those 4 links posted earlier. But since no one seems to want to believe that, I guess I'll just have to prove it to you.

1) Being stuck at the Kindle Fire logo means your device is in one of two states; in fastboot mode, or in normal mode but without a working system to boot to. This is explained in both the Frequently Asked Questions thread and the Fastboot Guide thread linked to within it. FAQ #16, Fastboot Guide

2) Also explained in the threads mentioned previously, is information on determining what state the device is in by paying attention to the behavior of the Kindle Fire logo as the device starts up. If the Kindle Fire is displayed brightly and stays brightly lit indefinitely, the device is in fastboot mode. If the Kindle Fire logo is brightly lit for a few seconds then flashes and/or goes dim, then it is trying to boot normally to a non-working system. With that knowledge, you can easily determine your next course of action...also based on the information found in the links provided. FAQ #16, Fastboot Guide

3) The key to fixing 99% of all Kindle Fire problems is getting access to custom recovery. There are two ways to access custom recovery when your device is malfunctioning, through FireFireFire, or through fastboot. If you don't have FireFireFire installed, the only option you have left is fastboot. If the device is trying to boot normally to a non-working system, then your only option for accessing fastboot is with a factory cable. FAQ #16, 17, 26, 29, 32, 33, Fastboot Guide

4) If your device is already in fastboot mode, and you are unable to change your bootmodes with the command line in Windows, it is because your drivers aren't properly installed.

There is no other possible scenario

. FAQ #14, KFFB - post #3

5) If you are using Windows, and you are unable to fix your drivers despite the wealth of information available to you for getting the drivers to work properly, then you use use Linux. FAQ #15

Your situation is no different. If I were to make an educated guess, I would say device is stuck in fastboot mode because your drivers weren't working properly...and you only have Microsoft to blame for that. As for Linux, it will not communicate your device using ADB or fastboot automatically. You have to either run the commands as the root user, or set up udev rules for your device. If you used the SoupKit to set up your udev rules using a LiveUSB,

you have to have working persistence

. The way it's configured now is to reboot in order for the udev rules to be loaded. If you don't have working persistence, everything you did prior to the reboot will be lost (This is also explained to you in the SoupKit thread).

With that being said,

you have NO RIGHT

to get offended if I would rather post a few links and expect the user to do the appropriate amount of research on their own to fix a problem THEY CREATED, than spend my personal time to tell every single user that comes to this forum with the exact same problems, everything that I have told you just now.

I wish you the best of luck in getting your device fixed, and I have no qualms about providing you support for the things in the aforementioned threads that you don't understand. But I WILL NOT hold your hand and tell you every single little thing that you need to know in order for you to fix your own device.
