[Q] Help me with the fastboot mode on my KF2 - Kindle Fire 2 Q&A, Help and Troubleshooting

Hello everyone, I have a Kindle fire 2 with 10.3.1 bootloader, and I want to install a jelly bean rom, but I canĀ“t install a 2nd bootloader or the 1-CLICK METHOD of fmkilo because my bootloader version. I need to downgrade first right? ok but to downgrade I need to get into fastboot... I don't have the cable yet. but I rooted and tried the adb shell comand to get into the fastboot mode. Perfect the tablet get into fastboot ... it says:
Fastboot (red font) and a kind of semaphore with the green light blinking.. but in the pc (windows vista basic) it says it found a new hardware named Otter2-Prod-04 but there is no drivers for that device, not in windows update. the amazon drivers doesnt work, the kfu drivers neither, I don't know what other drivers try... here is where I'm stuck...
To clarify if the kindle is normally turned on the pc recognize it like kindle fire -> andorid composite adb interface but if I use de adb to get into the fastboot mode It changes to the otter2-prod-04 and cant find drivers...
What can I do to fix this? where can I find the proper drivers...??
thanks beforehand for any help.
Update. I got tired trying in windows vista, then I tried on windows 7 and nothing and finally in a windows xp sp3 and on this last one it worked, the drivers reconigzed the kindle in fastboot mode, but when I tried "fastboot devices" it shows nothing. my nightmare continued few more days until I found this thread about kindle fire first aide... good utlitly ... I recommend this ... http://forum.xda-developers.com/showthread.php?t=2096888

[Q] Kindle Fire Really bricked

Please, please, really, help me out. My kindle fire is bricked, I tried Unbrick tool and a lot of other things, like installing again the drivers, the sdk, but nothing works at all!!
Here is the thing: When I was rooting my Kindle, my building got a blackout during the root process, and when the light goes on, my kindle was stucked on "Kindle Fire" logo. When I use adb devices, nothing shows. When I connect to Windows, it shows as a Unknown device, and when I try to install adb composite, it give a message saying that the driver android_winusb is not compatible with the hardware connected to USB. So, I can now really use this brand new Kindle Fire as a brick? I bought it on june 06 2012 !!!!!! Please, help me with this.. please..
Thank you very much
I was in the same place yesterday
Uninstall the unknown usb driver
Unplug kindle from usb
Reboot pc
Install drivers from kindle fire utility using the install_drivers bat
Plug kindle in, should recognize as adb device (if it shows up as a kindle uninstall those and reboot)
You may need to use kfu to get into normal bootmode if stuck in fastbook onc the drivers are set

Stuck in Kindle Fire logo mostly means your your KF is in fast boot mode. Try unplug your KF, get the latest KFU and reinstall drivers, reboot pc and reconnect KF.
Open KFU and select normal boot mode.

Thank you for the answers, but it is still not working. I did everything you told me, but its not working. My Windows 7 set the device as unknown. When I set it to normal boot mode, the program starts to wait for the device that is already pluged in.
kindle fire bricked at all
What else can I do? I have tried on Mac, on Linux and Windows, but its not working in any of these systems.

First figure out where it's getting stuck in the boot process. If the bootlogo appears on the display and stays that way without ever blacking out, then it's in fastboot mode.
http://forum.xda-developers.com/showthread.php?t=1668159
If it does go black before showing the bootlogo again, then it's no longer in fastboot mode and its trying to boot into something. In this case, you'll have to hope that it's getting far enough into the boot process that it can accept adb commands from your computer.
Either way, you'll have to make sure the drivers are working properly.
http://forum.xda-developers.com/showthread.php?t=1552547
The second one covers drivers, but the first 3 posts in general should be helpful to you. If it's not in fastboot mode and you can't get it to execute adb commands, you can either get a factory cable or open up the back cover on the device and use Firekit.

Need help rooting Kindle Fire 6.3.1

I'm using Win 7, I've edited the adb_usb.ini and put 0x1949 in there...I'm running the latest Kindle Fire Utility.
adb status says offline
boot status says unknown
I'm stumped..
dude...you're a badass!
I didnt get it to work on my son's Windows laptop, so I tried it on VirtualBox under XP and its working right now.
I think its because he already has an Android device installed...even though I uninstalled it, it still recognized the Kindle and didnt take my "update drivers" saying the latest drivers are already installed.
only problem now is that when I run KFU, did perm root and now it just stays in fastboot mode...cant do anything else.
nevermind.. with KFU, I got it to boot. whew!
Solved - the stuck 'ADB status: Offline'
At last - after seaching here for many days with zero success trying to get all sorts of drivers to work - the above did the trick for me using XP on an Acer Aspire One notebook.
Huge thanks.

[Q] Kindle Fire Driver Issues

Hey so a few weeks ago i tried to root my kindle fire, version 6.3.1 (to the best of my memory), on windows 7. I tried Kindle Fire Utility but the drivers wouldn't install so i found a different one and ended up bricking it. I was able to use an unbricking tool i found online which worked initially, but a couple of weeks later i restarted the kindle and now it is stuck in FireFireFire (yellow triangle), which i think is fastboot mode (correct me if i'm wrong). I have TWRP installed and have been able to load into it once, but was unable to fix the problem and now have been unable to load into it since. Kindle is mostly unresponsive now, but can turn on and off with the power button and turns on when plugged in. My computer recognizes the kindle as an unknown device and is unable to update the drivers. I have tried reinstalling the drivers from Kindle Fire Utility v0.9.9 dozens of times, yet still nothing. I went to the the "read before you post" thread concerning drivers and attempted to follow that process a few times, however after i have selected the new drivers and clicked next the computer determines that the best drivers are already installed, and prevents me from installing the new ones manually.
Thanks for reading, would be nice if i could fix this issue.
New user so i cant post links, I will put the link to the site i bricked it on in the comments if needed.
Just to get it out of the way: are you rooted?
If you are, try this:
Code:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
Make sure you have ADB set up before trying this.

No midroot it got stuck in fastboot.
Okay so i went and followed the instructions for installing drivers and was able to get my computer to recognize that it is an android phone when plugged in rather than an unknown device. Unbricking tools still wouldn't work, so i followed the instructions to the point where i need to do go to the "have disk" part. After selecting the proper drivers, the computer said that it couldnt update the drivers "since the device cant start (code 10)".

[SOLVED!] Kindle Fire Bricked on Logo Startup - KFU v0.9.9

I am total noob. Just want to make that clear from the get go.
I hesitate to start a new thread, but I have been working on this forever, and have not made any progress.
I have a Kindle Fire that I would like to run android on - I started the process with the Kindle Fire Utility v 0.9.9. Something went wrong, and it is now stuck on the Kindle Fire start up logo. I also can no longer see it in the device manager, nor is it responsive to anything in the Utility. (ADB status: Offline Boot Status: Unknown). I am at a loss, does anyone have any ideas? Your help is appreciated!
.................FIGURED IT OUT!..............................
Much thanks to the pooch who spent hours helping me troubleshoot.
What we (he) did, as far as I remember, hopefully this can be of some service to someone else out there.
1) Figured out that trying all of this on a Virtual Machine is not a good idea!
2) I somehow broke the bootloader in my first attempt, so none of my computers were recognizing the KF.
3) Created a Pendrive to run Linux (ubuntu). Here Requires a USB drive formatted Fat16/Fat32/NTFS, minimum of 2 gb.
4) Once I got Linux running, installed SoupKit.
5) Went through a few tries of booting, rebooting, into recovery mode until the Kindle flickered back to life!
6) Followed prompts on SoupKit to install TWRP, updated TWRP, install FireFireFire, install Android 4.2.
Good luck, I am happy to answer any questions - though I am no means an expert now.
What I have tried...more info
More Information:
I am running Windows7 in a VirtualBox on an iMac.
I bricked the Kindle a few weeks ago, after messing with it then, I bought a factory fastboot cable. Still no dice.
I have tried all turning on and off computer, on and off Kindle with it disconnected, connected, going through the KFU 4 seconds after starting the Kindle. Letting the Kindle's battery die, recharging.
I have deleted .android folder, reinstalled drivers, re-downloaded KFU.
I have tried on a different computer (Windows XP) The Kindle is also not recognized there.
I have tried booting into Ubuntu (however in the directions there, it said the FireKit is for more "serious" issues than my soft brick.
I am sure there is some small detail I am missing, but I have not been able to find it - and I am not knowledgeable enough to properly diagnose the problem. Again thanks for any help.

Sometimes KFU will show as Unknown even though it's really fine. I had the same issue as you. Try switching boot mode to Normal and see if that fixes it, it worked for me.

Thanks for the reply!
I tried that. When I type "fastboot getvar product" it says waiting for device or something similiar.
The advice applying to Device Manager don't get me anywhere, because my Kindle doesn't show up.
Any other ideas?

When using the stock bootloader (plain "kindle fire" boot logo), the fastboot command must always specify the custom vendor ID used by the Kindle Fire. For example, the commands above must be slightly altered to...
Code:
fastboot -i 0x1949 getvar product
fastboot -i 0x1949 devices
and likewise, all of the following commands will need the "-i 0x1949" switch when using the stock bootloader. The FFF bootloader's vendor ID has been changed to one that is normally recognized by fastboot, so the "-i 0x1949" switch can be omitted.
Now onto some more useful fastboot commands...
Code:
fastboot oem idme bootmode 4000
fastboot oem idme bootmode 4002
fastboot oem idme bootmode 5001
Using one of these commands will change the bootmode to normal (4000), fastboot (4002) or recovery (5001). Then issuing...
Code:
fastboot reboot
will reboot the device into the respective bootmode.
I've tried that as well...
Just so I am totally clear, this is what I did in relation to those instructions:
Opened Command Prompt - set the directory to C:/kfu/tools
Typed "fastboot -i 0x1949 getvar product" (with out the quotations, obviously)
<waiting for devices>
I plugged Kindle in, it powers on and the frozen logo pops up.
I also tried "fastboot -i 0x1949 oem idme bootmode 4000" and "fastboot -i 0x1949 oem idme bootmode 4002"
According to the guide it often takes multiple tries, I have done it over and over again.
I have also tried different orders of code, plugging in Kindle, and powering on and off.
Am I doing something wrong? Is there a specific code for my Kindle? (Not -i 0x1949)
Thanks!

Reinstall the driver then use kfu to reset the boot mode to normal.

By reinstall drivers do you mean clicking on "install_drivers" in the KFU folder? I have tried that.
Is there another method of uninstalling and installing drivers? Sorry if that is a dumb question!
If the devices is in fastboot which I believe it is it would show up as android adb interface, if it was attempting to boot to the system it would show up as android composite adb interface. If you are on xp or windows 8 this can be a bit of a tricky task. Android adb interface and android composite interface are two facets of the same driver. So yes I suggest rerunning the driver installation bat that is packaged with KFU. If perhaps you are on windows 8 you must disable driver signature verification and reinstall the driver. 3.0 usb ports have an issue with fastboot and can leave the device undetected.
Still not working

Thanks for the quick reply.
So I am on a Win7 and/or a Windows XP. Currently on both systems, when I plug it into the computer, with the Device Manager open, nothing happens other than the Kindle turning itself on.
Before it froze up, I saw it in device manager as Android ADB interface, and before doing anything at all, saw it as the default Kindle Fire.
On the Win7 system, I have rerun the driver installation bat over and over and over again, with absolutely no results.
On the WinXP, I have tried it, and for the life of me can't get it to install (it says install failed (Unsigned)). I never connected the Kindle up to this computer before it froze up, so I wonder if that is somehow causing the problem (it is trying to update drivers that don't exist?)
Am I doing something wrong with this? Can I uninstall or delete drivers, and totally start over?
If you are using a WinXP you must install driver manually.

How do I do that, when the Kindle does not show up as being connected? All the guides I have found start off with accessing from the Device Manager. My Kindle does not show up in the Device Manager...
okay well then you`re running xp use another computer getting the driver installed is hard even for the very skilled particularlly when the device is stuck in fastboot. Friend or relatives computer running windows 7 would be perfect. Otherwise it`s linux on a live usb booted on your xp machine.

Yeah so I have a Windows7. I have reinstalled the drivers (by clicking on the install_drivers.bat file in the KFU) over and over again, and I still do not get any recognition on the computer, or in the Device Manager when I plug in the Kindle.
Try different usb port, make sure they are usb 2.0. Is the logo static or animated? It possible that you broke the bootloader. At some point I would be willing to look at some things for you via teamviewer. If it is not driver related I fear your next move is here http://forum.xda-developers.com/showthread.php?t=1430038. Keep it on charger or off till it can be dealt with.

Thanks! I would be willing to give it a shot (teamview I mean) if you are willing.
I tried the Firekit before I began this thread, but I kept getting stuck trying to run the tool after booting into ubuntu. Perhaps that is a different thread topic, but I am more than willing to put more work into figuring that out, if it could be the key to unlocking this stupid thing.
I am having this exact same problem. Using Win XP i was able to get the ADB drivers loaded initially and used KFU to try to install TWRP. When it rebooted during that process it got stuck at the Kindle Fire logo. Since then I cannot get my computer to recognize the kindle. Like you, I feel like i've tried everything.

Trouble with flashboot drivers

Ok my ADB drivers are working perfectly fine and show up on the list of ADB devices but now there is a bigger problem. When I put in my flashboot cable on my CMD it still says waiting for devices and Windows is trying to install some drivers that fail. Otter2-prod-4 is what it says in device manager I know that is my kindle fire but until that works my first time to attempt to flash my kindle is dead. My kindle fire is rooted and is on version 10.4.6 if that is helpful but the quicker it is the better I'm hoping to try to flash slim cat 6 Rom on here by Sunday
