[Q] Kindle Fire 2 Boot Loop PC wont recognize - Kindle Fire 2 Q&A, Help and Troubleshooting

I have a KIndle Fire 2 that is in a boot loop with white and orange logo constantly flashing on and off. I rooted it and was trying to load CM on it. I have a fastboot cable but that does nothing. PC does not recognize it anymore. I opened case up looking for reset button like the KF1 has but could not locate one. Is this fixable?
The problem started after the OEM Recovery command was sent:
Step 3: Use fastboot to apply exploit files and reboot into recovery With the device powered off: connect your FASTBOOT USB cable(if needed) to the Kindle which should cause it to power on and enter "FASTBOOT" mode. Issue the following commands into your command/terminal window on your PC 1 at a time. (if you don't need a fastboot cable then power on the device after entering the 1st command below)
fastboot -i 0x1949 flash bootloader otter2-u-boot-prod-10.2.4.bin
fastboot -i 0x1949 flash recovery otter2-twrp-2.6.3.1-recovery.img
fastboot -i 0x1949 flash boot otter2-freedom-boot-10.4.6.img
(if using a fastboot USB cable swap to a normal USB cable before entering the next command)
fastboot -i 0x1949 oem recovery
If all has gone well, then your device should now be in recovery.

Does fastboot find your device ? Use fastboot with getvar command to check if you device is recognized with fastboot.
If ok, try to flash the boot.img

the fast boot cable does not put the device into fastboot and my PC doesn't even recognize it so how would I be able to issue any commands to the device

Where'd you get the cable from? I have heard cases here and there on the forum of people buying a fastboot cable that didn't work because it was just an regular cable being sold as such. I recommend the blackhat adapters myself.

OK so my pc does not have to recognize the KF in device manager for a proper fastboot cable to work?

Yes it does, you plug a fastboot cable in and it should show up as either a otter2,jem, or Tate device depending on the model, if it shows up as a android device bridge or something of that nature then the driver is already installed. Without a driver you can't interact with a device.
Edit: wait if you meant did the kindle need to be showing up already for the cable to work then the answer is no, the cable itself is what puts it in fastboot mode so the computer can detect it.

ok thanks so maybe the ebay "special" fastboot cable I got is bad. I ordered a black hat adapter and will try that

Factory cable questions

Hi, I recently bought a factory cable because my Kindle is bricked. I'm stuck at the kindle fire logo with no adb shell and fastboot says "waiting for device". I got in this situation by doing a wipe from twrp and then flashing the stock recovery (dumb, I know).
Anyway, with a regular cable I can do basic adb commands (adb reboot, etc).
With the factory cable my kindle isn't showing up under adb devices. Windows recognizes it and it shows up in the device manager. I've already re-installed the drivers and everything.
Here's an outline of what happens when I plug in the factory cable. This is starting with the kindle off.
Kindle turns on and goes tot he kindle fire logo and freezes. The power button is green with the factory cable. I noticed that with the normal cable it's orange. I'm not sure if this has any relevance at all.
Anyway, I'm wondering what I can do to get my kindle to show up in adb while using the factory cable.
If you need more info from me let me know and I'll add it.
A factory cable puts the device in fastboot mode, therefore will only accept fastboot commands.

I'm not sure if I'm missing something, but fastboot commands aren't working either. It's not showing up under fastboot devices and fastboot flash recovery hangs at "waiting for device".

The second post is about device drivers and what to look for in the device manager when your device is in fastboot mode.
It's also possible that you aren't including the vendor ID in your fastboot command. That's covered in the third post.

Thank you so much! I was able to flash twrp by using fastboot -i 0x1949. Now I've just got to choose a new rom to flash .

[Q] I've bricked my KF, no custom bootloader, Factory cable didn't work. Need help.

I'm stuck on the Kindle File logo boot screen.
I used this client to attempt to root my Kindle. I am rather inexperienced, and tried to apply a permanent root with superuser before installing a custom bootloader. In the process, i think it tried to install FFF, but would take an unusually long time to download and install it. So naturally, as any frustrated noob would do, i tried to X out of the window and unplug my Kindle. Bad idea. Turned it on, and it was stuck on the boot screen.
I've tried using a MOTO factory cable to start it in fastboot, but it would not work. There is a sticky at the top of this section that has instructions on how to unroot it, but the link to download important files just leads to some internet propaganda thing multiupload is hosting or something; I can not download the files.
SOLUTION:
shift +right click on Kindle Fire Utilities tools folder, select open command window here. power off your device leave it unplugged, type "fastboot -i 0x1949 getvar product" (no quotations). when it says waiting for device, plug it in it will power on in the terminal. if you get a response "product: kindle" type "fastboot -i 0x1949 oem idme bootmode 4000", hit enter then type "fastboot -i 0x1949 reboot" it should then boot normal use a standard cable for this, not your moto factory cable

Sounds like your booting to fastboot mode you need to download the drivers so you can set your bootmode back to system

Your KF is OK and you need to change the boot mode to normal by following the below commands
fastboot -i 0x1949 oem idme bootmode 4000
or
fastboot oem idme bootmode 4000
then fastboot reboot

Okay, I'm assuming i can do this through cmd.exe, but what commands do i need to type in to get to the point where i can type these in?
I've fixed it. Thanks to someone over in the Q&A section.
Turns out i was stuck in fastboot.
For anyone who discovers this thread in the future, here was the solution:
shift +right click on kfu tools folder, select open command window here. power off your device leave it unplugged, type "fastboot -i 0x1949 getvar product" (no quotations). when it says waiting for device, plug it in it will power on in the terminal. if you get a response "product: kindle" type "fastboot -i 0x1949 oem idme bootmode 4000", hit enter then type "fastboot -i 0x1949 reboot" it should then boot normal use a standard cable for this, not your moto factory cable
This worked for me, thank you very much.
I have this same problem, but I cannot get my computer to recognize that the Kindle Fire is plugged in. I have tried installing the KFU driver but that doesn't seemed to have worked.

If this doesnt work http://forum.xda-developers.com/showthread.php?t=1430038 you will need to aquire a factory cable so you can fastboot flash fff.bin and twrp image in order to then flash a rom because your system software is likely broken factory cable here http://forum.xda-developers.com/showthread.php?t=1392693 its possible you are stuck in fastboot but I doubt it if you get lucky and that is the case shift+ right click on the tools folder in kfu select open command window here power your device off completely leave it unplugged type fastboot -i 0x1949 getvar product when it says waiting for device plug in your powered off kindle it should then power on in fastboot mode if you get the response product: kindle then type fastboot -i 0x1949 oem idme bootmode 4000 it will say okay hopefully the type fastboot -i 0x1949 reboot it should then reboot in normal mode

[ISSUE] Kindlefire bootloop

I was trying to root my kindle today and decided to use the kfu.
I installed the drivers etc and started the kfu
http ://i.imgur.com/qNQgD.png
This is what the screen looked like, so i pressed 1
and then i pressed 2
http ://i.imgur.com/aAHRM.png
and the window said sending something and the kindle rebooted.
but now its stuck at the kindlefire logo screen. and anything you do in the kfu says it cant find the device.
i tried to use the firekit hoping it would fix the issue with the normal_boot script but all it does is hang at "waiting for device"
I know i probably did something really stupid, but if anyone could help me fix this i would be very grateful.

i tried :
Getting out of fastboot mode
To get out of fastboot mode, make sure the bootmode is set to something other than 4002 and reboot the device. The examples below will set the bootmode to normal and reboot the device.
With the stock bootloader...
Code:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
but adb and fastboot don't recognize that a device is plugged in, in device manager it shows as Android Phone, Android ADB Interface
Hardware ids show
USB\VID_1949&PID_0006&REV_0100
USB\VID_1949&PID_0006
i have no firefirefire, or twrp and am on unrooted stock 6.3 if that helps.
Disconnect the KF from the computer
Make sure the KF is off by pressing and holding the power button for around 20 seconds
Issue the first fastboot command and it will indicate that it's <waiting for device>
Connect the KF to the computer and it will turn on automatically
The first fastboot command should get sent to the device as it goes into fastboot mode
Issue the second fastboot command to reboot

The fastboot executable you are using does not recognize the "-i" switch... notice it's not listed under options.
Download KFU and use the fastboot in that distribution.

[Q] "fasboot getvar product" command not working

I have a kindle fire (first version Amazon came out with) which I rooted and installed CM7 on. The other day, I turned it on and it's just rebooting to the yellow triangle (fire logo). I ordered a fastboot cable and plugged it in but when I run 'fastboot getvar product' the boot loop still continues. The only output from fastboot is:
# fastboot getvar product
< waiting for device >
product: kindle
finished. total time: 0.000s
Any idea what's wrong?

Uh...I thought the point of issuing the fastboot command was to get the Kindle out of the infiinte boot loop so I could reflash a recovery image, not to actually get the product ID: "Issuing a fastboot command like...fastboot getvar product to the device during this time will stop the fastboot countdown and enable fastboot mode indefinitely." Am I supposed to just try and flash the recovery image via fastboot while the thing is rebooting every 5 seconds? (eg:
fastboot flash recovery \path\to\recovery.img).

The 'getvar product" command, as you would think, just displays the product name. The point of using it is because, like most other fastboot commands, it waits for a handshake from the device before executing, but doesn't do any actual manipulation. The stock bootloader listens for such commands during the first few seconds of the boot process. As soon as one is detected, fastboot mode is then enabled.
You use fastboot mode to overwrite partitions with a disk image, which is what is needed many times to restore the device.
But your problem seems to be a (near) dead battery. The device has to boot to a certain point before charging is enabled so you'll have to use a different method to get it to charge. When you hold the power button, a countdown begins. During this countdown, one of the things that happens is that it prepares the device to be charged. The best way to do this is hold the power button until the device shuts off, then plug it into a power source and immediately hold the power button to shut it off again. If you can get the device to stay off while plugged in, leave it alone for several hours before starting it up again.
With a good charge, you should be able to restore your device using fastboot to replace the boot, recovery and system partition images (depending on what caused the "brick" in the first place).

I've had it plugged in via USB for a day or so but it just kept rebooting so I just dug out a wall-wart charger and plugged it in. It's not rebooting at least. It came up to the FFF logo and stayed there so I think you've found the problem. I unplugged the wall-wart and plugged in the USB cable and it stayed in fastboot mode :good: I turned it off with the power button and will see if it just powers on normally later today. Thanks!
Hey, just an update. I got side-tracked with some other stuff and didn't get around to fixing my kindle until today. I plugged it in via the wall-wart charger for two days straight. Plugged in the regular usb cable and it booted to the FFF logo (yellow triangle) but wouldn't go any further. At least it wasn't powering off now... I was going to re-install u-boot and TWRP but figured I should at first try re-setting the bootmode as I recall that getting messed up once before. I ran
fastboot -i 0x1949 oem idme bootmode 4000
Click to expand...
Click to collapse
and then
fastboot -i 0x1949 reboot
Click to expand...
Click to collapse
and Cyanogenmod came back up without any further monkeying around! Thanks again for the help!
