Fastboot Help

Ran "adb reboot bootloader and my kindle2 rebooted into fastboot mode, with the green and red light "stop light" on the screen. The Green light is blinking. The problem I am having is that my device comes up on my computer as Otter2-Prod-04 and I have no idea how to install fastboot drivers.

Use KFAID and install the adb drivers that come with it.

If your device is showing up as stated... Fast boot drivers are installed.
What is your goal?

Windows 8, but i've been thinking of creating an ubuntu partition because it seems people have a lot less problems with adb and the sort with linux.
I've tried the kindle fire drivers from the sdk, and the kindle fire hd drivers that some people used to root their kindle 2. had no problem getting my kindle fire to show up with adb. I've tried editing a driver to add the hardware id's that come up with the driver.

Very strange as the adb driver and fast boot driver are one and the same..
I assume you turned off driver signing and installed them manually (if not, do so)

What's the issue?
You're in fastboot.
That's what you want, you're done.
If you THINK there is an error with your PC connecting to the KF2 in fastboot, then try stuff with ADB. You say you want fastboot but you already have fastboot enabled. There is nothing more you can do to.....get more....fastboot?
Now, if ADB is having issues, then you should post what kind of errors or issues you're having, and then hopefully we can help more. As of now though, it seems like you're already at where you want to be.

I've got the driver installed after turning off the signature checking thing.
I just thought I would be able to issue fastboot commands, whenever i try and do that I just end up with waiting for devices. Not a big deal , my device is working just fine so it's not like im stuck or anything. Just trying to further advance my android knowledge.

Hey man, can you help me? How did you install ADB driver? could you be more specific on this turn off signature checking? I'm using windows 7 and even I manually install driver and did everything that you did I still have the yellow triangle in device manager and cant be detected in adb that's why I can't sideload files.

you've probably already have them installed. in device manager, right click on the yellow triangle and click "update driver" when it asks you if you want to automatically search, choose "browse my computer for drivers", then click "choose from a list of installed drivers" scroll down the list till you see "kindle" click on kindle and the driver you want should be called "android composite adb interface" that's how i got mine to work

Kindle only shows red screen

Ok im posting in hopes to help someone else and myself.
DEVICE: 1st Gen Kindle Fire (D01400)
PROBLEM: Kindle quickly flashes stock logo then displays red screen.
I created this problem by using the wrong root tool (Qemuroot) [This tool is made for a Kindle Fire HD]
I bought a fastboot cable i hopes to use KFU/KUU to unbrick the device.
However Windows 8 only shows the device driver listed as Otter2-Prod-04 (Unknown Device) I proceeded to install the ADB drivers, even manualy assigned the device driver, and disabled driving signing and reinstalled drivers. (Drivers appear to install correctly however won't show up in connected adb devices.)
At this point im going to use SoupKit. I will post the outcome.
If you have had a similar problem or know of a fix which I have yet to research please let me know.
Thanks

Tested with Ubuntu linux using soupkit & firekit.
Both resulted in <Waiting for Android device> same in windows as well.
So I tried another computer also running windows 8, installed fresh SDK/Java/Drivers.
Once again had to force the driver to replace the unknown device "Otter2-Prod-04" now the device says its working in device manager yet nothing in ADB or fastboot.
I will add when I plug the device in using the fastboot cable it shows a red fastboot text and a stoplight green is flashing.
At this point im stuck and have reached the end of google. Yup thats right the very last page.

More hours put into this. I can issue fastboot commands. So this now turns into a question.
Is it possible to restore my kindle using fastboot?

You should be able to if you can push fff and recovery over and flash them via fastboot
Should enable you to have recovery back and work from there

Well I killed my kindle.
Pushed the FFF via fast boot and now the device no longer powers on, no lights, no sign of life.
fastboot -i 0x1949 flash bootloader <name of firefirefire image here> which was u-boot
guess its time to cash in on my my rapid exchange at Best Buy

New battery ? Can you explain never heard of this before. I was under the impression that I killed the bootloader.

I was just thinking that the battery may have died

Not detected in boot loader.

So I'm trying to flash the L preview. I plug my n7 in and do adb devices and it shows up, I adb reboot bootloader and it boots into the boot loader, but while in it if I do adb devices nothing comes up and if I do the flash-all.bat it just stays stuck on waiting on device. And yes I have USB debugging, and just updated drivers and installed SDK fresh. This just seems odd.

When you are in bootloader mode, the correct command to list devices is: fastboot devices
Let me know if that command gives you a device id.
If it does not, then you must get your drivers situated.

Well not working while using the flash-all.bat would still indicate it's not recognized in boot loader mode. Which is weird when it is while its on.

I already suggested what needs to be done, you need to get your drivers working correctly. There are different drivers for the different modes.
Here is what I did to get my N7 2013 recognized in every possible mode: http://forum.xda-developers.com/showthread.php?p=50253887#post50253887

Do you have a syncing program for your handset/tab installed?
If so I'd uninstall it as they tend to take over the USB when you plug your device in, changes the USB port com ID and only meant for an up and running system and not in bootloader/recovery/etc
As for an actual response as in an ID/model/etc using adb or fastboot I've never seen it shown when I've tried it even with official and unofficial drivers others have had responses with!! ..but not had any problems flashing except with a sync program on pc
(personally never use sync progs since then )

device descriptor request failed

Hi I did a search but couldnt find any info on this.
I followed the steps in trying to install the drivers for first gen kindle fire on win 8.1.
Drivers installed fine but when I plug in the kindle fire I get device descriptor request failed in device manager. I've tried reinstalling the drivers. Different usb cable and different usb ports and same issue exists.
Has anyone had this problem and know a solution?
Thanks!

I first tried using the drivers from your thread [How To][Root] Kindle Fire 1 update 6.3.3 and Flashing FFF/TWRP [2014].
Did the advanced driver install from 8.1 and I got the device descriptor request failed error.
I then tried using the drivers from [HOW-TO] Amazon Kindle Fire Signed Driver for WinXP/Vista/7/8/8.1 thread. Drivers installed fine but I get the exact same problem.
Kindle is on version 6.3.3. Only thing i havent tried with a factory reset.

Kindle doesnt show up. It shows up as Unknown usb device (Device descriptor Failed)
I have tried to uninstall the unknown usb device but to no avail. I just tired a factory reset and that didnt work either. Im at a loss.
I've also tried installing manually by pointing it to the folder and it tell me the best driver has already been installed.

Have access to a Windows 7 pc?

Unfortunately i don't. Do you believe it's a windows 8.1 problem? I've been searching for some answers and it appears that might be it.
I was tempted to VM win10 and see if it worked in there.

KF2 Fastboot Drivers?

I recently soft-bricked my KF2 while trying to install 2nd-bootloader on it (solid red screen). I just plugged it into my computer via a fastboot cable and it got to the fastboot screen perfectly fine. From here, I cannot access the device to recover it.
Any fastboot command gives me "Waiting for Device"
fastboot devices returns a blank line
It's listed in Device Manager as otter2-prod-4 and I can't seem to get any drivers working for it.
Does anyone know if there's anything I can do about this?

Make sure you're using the -i 0x1949 parameter in your fastboot commands. If that isn't helping, we can continue with driver installation. Do let me know if you're using Windows 8+/10, as the driver installation process will require an extra step for those Windows versions.

If you're using Windows 10, you need to disable driver signature enforcement in order to install the Kindle drivers. Here's a tutorial to do just that. After the reboot, install the drivers like normal and then reboot. After that, your kindle should be recognized.
