[Q] Bricked Kindle. I use fastboot, but always get < waiting for device >

Yesterday, I got the Update 6.3.1 and because I have CMW installed, it blocked the update and I get the yellow triangle. Then I changed the recovery from CMW to TWRP and my kindle update successfully with stock bootloader and recovery back. And I can get in the system.
I want to root it again but on my Mac, I cannot use the KFU, so I use the method here (http://forum.xda-developers.com/showthread.php?p=24129239).
After I issued these commands:
"
adb push fbmode /data/local/fbmode
adb shell chmod 755 /data/local/fbmode
adb shell /data/local/fbmode
adb reboot
fastboot -i 0x1949 flash bootloader <name of firefirefire image here>
fastboot -i 0x1949 flash recovery <name of recovery image here>
"
the terminal returns something like "Could not get PIPE properties" and it stucks here. And later, I typed ctrl+c to stop the command and "fastboot oem idme bootmode 5002
fastboot reboot"
Then the screen is black and blank. I do not know what to do. I have tried fastboot but always get "< waiting for device >". Even I hit the power button for 1 minutes, the light is not on and the screen is still black. But it seems that the battery is stll a little bit hot, which may indicate that it is using the battery. What should I do now?

You could just keep holding the power button down for a long time maybe you will get it to boot but otherwise I believe you need a factory cable. http://forum.xda-developers.com/showthread.php?t=1550999

Thanks for your reply!

Thank you so much! I ordered a factory cable and it is on the way. No matter how long I push the power button, nothing happens, no power light, no backlight....When I charge it, the charger get hot, which may indicate it is being charged. Can a factory cable save it? I guess I may flash the wrong bootloader. I should unzip the u-boot-firefirefire-1.2.zip file and then flash it. But I flash it directly without unzipping. Such a silly mistake!

You don't unzip it just flash it in recovery but look at this post too http://forum.xda-developers.com/showthread.php?t=1392693 there is a new bootloader here http://forum.xda-developers.com/showthread.php?t=1632375 follow the instructions you most likely corrupted the bootloader partition flashing a new one will fix that but you need to get to a state where you can until then your in limbo with a draining battery factory cable is maybe your only rescue. I'm not familiar with Mac so I can't really help ya there http://forum.xda-developers.com/showthread.php?t=1430038 good luck

I use the command "fastboot -i 0x1949 flash bootloader <name of firefirefire image here>". Does the "<name of firefirefire image here>" is like "u-boot-firefirefire-1.2.zip" or "u-boot.bin"? Sorry, but I am quite confused.

When flash with fastboot you need to flash the u-boot.bin file
The zip file is for flashing by TWRP
they are used for two different method.

[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.

Try the iso I made post 7 http://forum.xda-developers.com/showthread.php?t=1413358 or just run your own http://forum.xda-developers.com/showthread.php?t=1850038

Please Explain Red Wipe Screen

I have tried several times to get CM 10.1 installed on my Kindle Fire 8.9 and every time I get the red wipe screen trying to install the 2nd boot loader. After searching through the forums I have not found a definitive explanation (not that its not out there, but i didn't find one) of what causes the red screen, just how to recover from it.
I have tried using HashCode's process
http://forum.xda-developers.com/showthread.php?t=2128175
and also Option (41) in KFFirstAide
Can someone please explain what the red wipe screen indicates on the Kindle Fire 8.9, so I can avoid it and get the 2nd boot loader installed?
My Kindle is currently running Version 8.1.4 installed from the latest KFFirstAide (option 7). I have successfully rooted the device and I have been able to recover after the red screen each time.

I used this tool KFHD_SRTv2.1- 8.1.4 To get into fastboot when I had the solid red screen then used option 7 to completely wipe and restore their is probably another way to just do the boot but it did work for me (did it today even)
Turn the kindle off (hold power down)
Load the KFHD_SRTv2.1- 8.1.4 tool using run as administrator
then use option 1
once your kindle says its in fastboot then close that utility and run the First aid

I know you said you aren't on 8.3, but it sounds like the bootloader issue Hash talks about in step 4.5 of his post. You could try flashing the bootloader he posts in that step to see if that fixes your issue. I had the same problem, until I flashed it.
Just an idea, I am in no way an expert just a tinkerer.

I too have the red screen, I tried to use the SRtool but was unsuccessful in recovering, can u provide anymore information? i'm really freaking out a little because i'm new to this stuff

I think fattire said Amazon enabled fastboot in this state. On KF2 and KFHD7, this is possible with a factory cable. I guess it's also possible that they have enabled the use of the factory cable for the KFHD8.9, but I'm only speculating.
Before the update, flashing unsigned boot and recovery partitions without the 2nd bootloader properly functioning, the device just wouldn't turn on. Now, not only will the device turn on, but some are even fixable in this state. I'm wondering if Amazon realized that wasn't cost effective to send every broken modified device to a specific secure location to get reflashed.

I don't quite remember what I did, but I was able to fix the "red wipe" screen on my Kindle 8.9.
I think I got this when I first tried installing 8.9StariROM when it was first posted on the forum. I did not know that the red screen could appear if TWRP was not installed already, and I think that's why I got the red screen error.
I didn't really know what it was all about, but somehow I was able to make my kindle go into the fastboot using this command (fastboot -i 0x1949 getvar product) and basically followed the instruction here: http://forum.xda-developers.com/showthread.php?t=2128175
I kept getting device not found error on ADB commands, so I skipped to STEP 4.5 and ran below commands in order: (of course, I downloaded all those files as well)
fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin
fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.3.0.img
fastboot -i 0x1949 flash recovery kfhd8-twrp-2.4.4.0-recovery.img
then I think I ran fastboot -i 0x1949 flash system starirom-system.img to load the system image and I was able to have a working kindle 8.9 again.
I hope this helps.

Here is what I did to get myself out of trouble after screwing around with my KFHD 8.9 and getting a red screen (NOTE: I am assuming you have already installed the proper drivers so your PC can recognize the Kindle Fire HD):
1) Downloaded the above-mentioned KFHD SRT tool from here: https://docs.google.com/open?id=0B4lZEJI5lYeMR1YteUt2MGxZTGM) and the boot.img and recovery.img from here: https://drive.google.com/folderview?id=0B4lZEJI5lYeMNGdXMHI3T3pKM2c&usp=sharing
2) Unzipped the SRT tool into a folder on my Windows 7 boot drive (C:\KFHD_SRT_v2.1), and copied over the two .img files to the /images sub-folder.
3) Ran SR Tool.bat in Admin mode (right-click, Run As Administrator, click Yes to accept)
4) Turned off my Kindle by holding the power button 10 seconds until the screen was off
5) Chose option 1. Enable Fastboot, chose "n" when the tool asks if the device is turned on, then pressed the power button once on the Kindle to turn the screen on. Voilà, I was in Fastboot mode.
6) From a command line prompt (started in Admin mode as always), went to the /images sub-folder of the KFHD SRT tool and typed in the following commands, one at a time (just press Enter at the end of each, and wait until done):
fastboot -i 0x1949 flash boot boot.img
fastboot -i 0x1949 flash recovery recovery.img
fastboot -i 0x1949 flash system system.img (note: this may take a few minutes, depending on the speed of your USB port)
7) Still from the same command prompt, rebooted the tablet using the following command (type it in and press Enter):
fastboot -i 0x1949 reboot
I was back in business from there.

Can we get this as a sticky in the Dev Section? it took me 2 weeks to get my system back from a red screen that the below was able to do.

[Q] TWRP flash failed but firefirefire installed, now I can't get to fastboot mode

I've been trying to root my Kindle Fire running 6.3.3. I bought a fastboot cable and got it to boot into fastboot mode to flash TWRP and firefirefire. I ran the commands and TWRP failed but firefirefire installed. Now when the kindle boots I get the firefirefire bootloader but it cant boot into the recovery because the TWRP never installed. Also, I can't get it to fastboot anymore, not even with the cable. Can anyone please help me get TWRP installed? I've read many forums and tried about everything I found.

FFF bootloader supports fastboot commands, but the flash command is now
fastboot flash recovery file name
ie drop the -i 0x1949
Code:
fastboot flash recovery openrecovery-twrp-2.6.3.1-otter.img
because the fastboot mode window is short
with kindle connected to pc, power off kindle, enter commands, then power on kindle

I've been trying this for about 30 minutes or so with no luck...I even downloaded a different version of the twrp image. Do I have to wait for the fastboot screen to start the command or do I start the process before powering on the device? I'm not really sure what I'm doing wrong here.

Should be able to do it either way but I press enter, before the power button
This will not work if drivers are not correct
could try
Code:
fastboot devices
as a test should get something like
Code:
123456789 bootloader
back in command prompt

I finally got it to work and I can't thank you enough. You were right. I knew my computer recognized the device with adb in normal boot but my computer wouldn't recognize the device in fastboot mode until i reinstalled the android driver while it was in fastboot mode. Now I have a custom ROM running Google Play apps! Again, thank you!

Hey, I don't know if this will help others, but I had a hell of a time trying to get my kindle to recognize while in the bootloader/fastboot mode... It frustrated me so much that I had to write about it.
I recently switched to Windows 10, so it seems like my computer is relearning drivers and stuff...
My kindle was fine when on, and I could issue adb commands from the main screen, but when in fastboot mode, I couldn't get it detected. I knew the drivers were an issue, but I couldn't figure out how to do it. I looked at Amazon's support pages, went through the SDK route, tinkered with the adb.ini and so forth... to no avail.
Post after post said that the easiest way to install the drivers was through the Kindle Fire Utility, but for some reason, the drivers in the .bat file kept failing and would not load. It took a good few hours to figure out the solution.
When I asked the Web why the drivers kept failing, I came across a post that said Windows was actually blocking unknown drivers from loading onto my system. I really wish Windows had told me that instead of just saying "Fail"...
I had to hold down the shift button and click restart on the start menu, and when the computer restarted, I when through: troubleshoot -> advanced options -> startup settings and clicked on Restart. It eventually gave me the option to disable that signature verification [F7]
My explanation is crude, because I want you to look it up properly. Just search for "disable driver signature enforcement" and you should be fine.
Hope this helps others out. I may have to revisit my own post just to see how to do this again.
