[Q] KFU rooting 6.31 - Kindle Fire Q&A, Help & Troubleshooting

Ok, I am attempting to root my Kindle Fire running 6.3.1, I am new to rooting so bear with me. I have downloaded the latest KFU and can't seem to get the ADB status to show as online. So I downloaded SDK and zergRush when I use the SDK platform tools in the windows cmd and use "adb devices" it shows that it is connected, attempt to push zergRush get the hellions with blue flames error. zergRush not working. How can the device be connected when I'm running SDK but the KFU won't recognize that it is connected. I have tried to push fbmode to it and it says access is denied. Is there something I'm missing here? I want to root and install jellybean. Please help.

would recommend to read this first to understand how it works:

in fastboot mode cant flash twrp
ok, now i think i have a problem for real. sorry for being so retarted about this, when i started to reboot into recovery to install FFF i missed part of the command in fastboot -i 0x1949 reboot now it just says waiting for device.....

could you try "fastboot -i 0x1949 getvar product" and "fastboot getvar product" - one should return "kindle" to test if fastboot is working.
i use to put the .img file in the same directory where the fastboot.exe is located.
furthermore i use c:\adb or something like this to avoid long path names and special characters.
do you still have the original bootloader or fff ?

device not connected...
it still says waiting for device, the kindle is at the stock kindle boot screen, but my computer made the device disconnect and reconnect noises so i checked the device manager and now it says unknown device under USB controllers.... i think i messed up.

what do you mean with stock kindle boot screen ?
the orange "kindle fire" or the unlock screen of the system ?
if you have the unlock screen simply plug the kf off and power it down.
reinstall the drivers (install_drivers.bat) and then plug it in again - it should power on by itself.

boot screen
silver and orange kindle fire screen

nevertheless you have a driver issue and have to reinstall the drivers.
the kf seems to be in fastboot mode ...

unknown device
I tried re-installing the drivers manually and it says drivers are up to date for "unknown device" when I use the driver installer that came with KFU it says the drivers are installed properly.

gave you a pm ...

I'm having this same problem. It's apparently stuck in fastboot. I can't even figure out how to type in adb commands or fastboot commands (meaning I could before and now when I tried it says command not found, but I didn't change anything. It won't recognize my device and when I try installing the android-winusb.inf it says it won't let me. I don't know what else to do. Any help would be appreciated. My Kindle is listed as unspecified device.

You are only soft bricked. When I asked what happens when u plugged it in, I mean in device manager not in the kfu. Device manager needs to ee the the kindle as adb composite device. If it does not, then you need to get the right driver.
You are stuck in fastboot. You simply need to issue the right reboot code and you will be fine

he is absolutely right, this happened to me and nothing would work until I got a factory cable
This is a typical problem with KFU.
You need to go to your device manager and uninstall both the adb and android drivers then reinstall them manually. Sometimes it helps to restart your computer and Kindle afterwards. Make sure your device manager says both "Android Phone" and "Android ADB Interface" NOT "Other Device" and "Kindle".
When you are stuck at the boot screen it means you are in fastboot mode. In fastboot mode your device will only recognize fastboot commands. If your device doesn't recognize fastboot commands (KFU uses fastboot commands to change boot modes), 99 times out of 100, it's a driver issue.
A factory programming cable, while nice to have, is not usually necessary. A factory programming cable does two things. It provides power directly to the device instead of the battery AND forces the device into fastboot mode (stuck at boot logo). Since most of you with this problem are ALREADY in fastboot mode, a factory cable would be pointless.
Make sure you are 100% certain that you have the correct drivers installed and configured properly and then use the command prompt to change your bootmode to 4000.
In command prompt, navigate to the folder that contains fastboot.exe and enter the following commands...
fastboot -i 0x1949 oem idme bootmode 4000
fastboot reboot
(or hold power button for 30 seconds)

i have the same problem as you it fills good to not be the only one

Stuck at KindleFire white/orange logo. Unresponsive to ADB commands.

First off, thanks to everyone on here who's posted numerous help guides that have helped me in the past. I've rooted several phones in the past and figuered I'd try to root and install Jelly Bean on a Kindle Fire I won at a work event (woohoo!).
The problem right now is the kindle is stuck in fastboot (no root, twrp installed) it boot into the non-animated white and orange "kindle fire" logo screen and stays there.
What I did to put it there:
On a Windows 7 machine, I used KFU 0.96. After reading instructions, I installed TWRP.
Since then, it is not repsonding to adb commands. It will mount the drive to the computer, and the drivers show it's using the correct one from Google Composite device.
After researching, I found someone who mentioned that after several restarts, and smashing "normal boot" commands thru adb while the kindle was starting up (and before it went unresponsive) he was able to move along. When I did this (with KFU), Kindle went into TWRP. From there I followed instructions on flashing pre-rooted 6.2.2 (as the guide indicated, doing wipes) but the flash always failed.
Assuming something wasn't working with Windows, I've gone home to my macbook running Ubuntu 12.04, and while installing SDK from Google, I can not figure out how to get the google sdk running. I followed this guide http://forum.xda-developers.com/showthread.php?t=1550414 but I can't get to step 5, I cannot get the Android SDK Manager to run!!
I have access to dozens of Windows computers, I'm fine with going back to them, but everything I've read makes me think I've got a better shot with Linux due to driver problems on windows.
Also, when I had TWRP loaded on the Kindle, and connected it to KFU 0.96 it said my boot mode was 0x5003.
fastboot commands will not execute. I'm sending them like this:
(Devices list)
[email protected]:~/Android/KR$ ./adb-linux devices
List of devices attached
???????????? no permissions
fastboot:
[email protected]:~/Android/KR$ fastboot getvar product
fastboot: command not found
Someone had a similar problem here- http://forum.xda-developers.com/showthread.php?t=1765546 but I want to see if I should follow that thread or try something else instead, before I go making more changes.
Thanks for reading! Will gladly send pizza to someone who can help
I'm not an expert at fastboot and adb stuff but I can try to help.
As far as I know, the Kindle needs to be in fastboot mode for you to be able to use fastboot commands. The boot mode has to be 4002.
Are you still able to connect to your Kindle using KFU?

yes. but it also spits out "-exec '/system/bin/sh' failed: No such file or directory (2) -" when I send the command to reboot into fastboot 4002, the kindle then reboots, and has the white and orange "kindle fire" logo.
also: C:\KFU\tools>fastboot devices
returns blank, goes back to prompt. so I try
C:\KFU\tools>fastboot devices
< waiting for devices >

Try uninstalling and reinstalling the drivers. If your in fastboot mode, adb wont work. After reinstalling the drivers, type:
Code:

If the drivers installed correctly, these commands should work and get you out of fastboot(which it seems your stuck in)

"-exec '/system/bin/sh' failed: No such file or directory (2) -" means your system software is broken, so it probably won't boot. In addition, either the "sh" binary doesn't exist there or the KF is not mounting the system partition to let you execute "sh" to run "adb shell" commands. To clarify, you need "/system/bin/sh" to run any "adb shell" commands. Because you don't have access to it, you cannot change the bootmode this way. There is no "command to reboot into fastboot 4002"... you have to set the bootmode to fastboot (4002) and reboot it. Because you cannot run "adb shell" commands, you cannot change the bootmode. Your next reboot just boots into whatever the bootmode happened to be at the time you tried (but failed) to change the bootmode. All of this is spelled out here...
http://forum.xda-developers.com/showthread.php?t=1668159
It's very likely that you'll have to get a factory cable to force the device into fastboot mode... that is unless you want to open the back cover up and tinker with the motherboard.
Also, you have permission problems when you try to run adb. You either have to run adb as root, or use this guide...

for real, I probably would have paid $50-60 too, it should be an easy fix with a factory cable. (which I already have one of after I bricked my kindle once)
Also, as a side note - Amazon will replace it for $100 "not under warranty" because you bricked it through the tinkering process.
Actually, it turned out better than I could have planned. I told the company whom gifted to me t did not work, they sent a bike ,messenger to exchange it for me! Naturally the first thing I did with the new one was fire up kfu .96 and it worked perfectly this time. Stoked on this hashtaag jelly bean ROM. Hate the keyboard tho. And Google cards are fc'ng.

[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:

as a test should get something like
Code:

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.

[Q] Stock 1st gen KF stuck on logo screen

Been through a bunch of threads here and elsewhere trying to figure this out. My daughter brought her 1st gen KF to me last night with it stuck on the logo screen. Here's the things I've tried so far:
Hard reset (with power button): Held down for 20 seconds to a minute. Doesn't work.
Installed adb and fastboot on my Mac OS X system. I can get adb responses, "adb devices" returns <device ID> device. The KF will also reboot with the "adb reboot" command. I followed the suggestion at noelarlante.com/kindle-fire-stuck-at-boot-logo-solved (can't post link, new user), but when I ran the "adb shell /data/local/tmp/fbmode" command, it returned "couldn't write bp1, panic!"
Also tried running "adb shell idme bootmode 4000" and "adb shell idme bootmode 4002", but get permission denied as the response
Fastboot commands don't work, I just get <waiting for device>
On the Windows 7 side, I installed the Amazon drivers and the KF is recognized without any problems.
I then tried the Kindle Unbrick Utility (v1.1). If I run the "Stuck at logo" option, I get error: device not found, even though Device Manager lists the Kindle Fire without any issues (shows up as Android Composite USB Interface). "Recovery Loop" option leaves me at <waiting for device>.
Turning now to the Kindle Fire Utility (v0.9.9), the KF is listed as ADB Status: Online, but Boot Status: Unknown. Using the options on the bootmode menu, the KF will reboot, but I get the "couldn't write bp1, panic!" message and Boot Status stays unknown. If I try to install TWRP, "couldn't write bp1, panic!" comes up again, then <waiting for device>. Nothing more happens.
Any suggestions beyond what I've tried so far? The key step seems to be getting past the "couldn't write bp1, panic!" issue.

OP says nothing about fastboot commands.
See fourth bullet point in list above.
Will the fastboot cable override whatever has failed to keep the KF stuck in the boot loop? If the KF is accepting (some) adb commands, does that imply it is in normal bootmode?
Thanks again, got the cable ordered.

Fastboot cable forces Kindle into fastboot mode.

Problem is solved. Here's what I did:
As sd_shadow suggested, I got a fastboot cable. This worked to get the KF into fastboot mode.
Once in fastboot mode, I was able to use Kindle Fire Utility to load FireFireFire and TWRP onto the Kindle.
TWRP from KFU was kind of an old version, so I got the latest version and did a fastboot flash recovery to load up that newer version.
Also downloaded the stock Kindle ROM. For some reason, the sdcard partition wouldn't mount in my Win7 VM, but did mount on my Mac, so copied update.zip from there.
TWRP (2.8.5.0 otter) then wouldn't install the ROM. Tried loading in the 2.8.5.0 blaze version, same deal.
Some Googling on this same problem turned up the fact that TWRP 2.2.2.1 would correctly install the Amazon ROM, which in fact it did. Later builds must have some kind of bug, but if this only affects 1st gen KF's, probably not an urgent one.
Rebooted and back in business. :good:
Fastboot cable is the key ingredient in this situation.
Twrp versions 2.8.X.X have issues for some people, use 2.7.1.0 for custom Roms, 2.2.2.1 for stock.zips

Fire HD 8.9" Stuck at Boot Screen, cannot connect fastboot or ADB

Hello all,
Recently recieved a Fire HD 8.9" (OS 8.5.1) from a family member that upgraded to a newer Fire HDX. I decided to convert the tablet to Pure Android to give it another lease on life, I followed the instructions here https://forum.xda-developers.com/ki...t-install-twrp-android-fire-os-8-5-1-t3278286 and I goofed. I forgot to "apply stack override" when flashing and when rebooting to go into TWRP it froze at the boot animation and will not connect to my PC (you can watch on device manager and it appears for less than 2 seconds before disconnecting). I have been out of the rooting and installing custom ROMs for a few years and I am lost as to what to do next. Fastboot and ADB commands are something I have not used before (I do have the latest Android SDK installed) using the command prompt doesn't scare me and I am used to fixing Windows OS issues using it. I have read a couple of threads saying to flash the factory system image to the device using fastboot but haven't found a step-by-step on exactly how to do so. I also have installed the driver for Kindle Fire HD 8.9" JEM found on XDA if that helps. TWRP is/was installed prior to rebooting, would just like to get back to where I can try again. This community has helped me a lot in the past when it has come to my Android devices.
Thank you,
Coop
I have the exact problem and and have been trying to find the solution for a week but nothing works. If I by chance find something I will come back and post it.

To go to fastboot - Shutdown your device.. and then make sure you have adb and fastboot installed in your pc/windows then type in
HTML:
fastboot devices
and hit enter. This should say <waiting for devices>
Then, connect your kindle hd to PC. It should show... fastboot mode
First make sure you have the correct device.. type the following... it should say ...jem
HTML:
fastboot -i 0x1949 getvar product
If you are able to get to fastboot mode.. if you have the stock image for boot, recovery, and system backups.. do the following
1.
HTML:
fastboot -i 0x1949 flash boot [your boot image file]
2.
HTML:
fastboot -i 0x1949 flash recovery [your recovery file]
3.
HTML:
fastboot -i 0x1949 flash system [your system/os file]
you should be able to restore to factory os.. Also, this worked for me in Mac.. had some issues using PC
I have the same situation and my Fire HD 8.9 is not detected by fastboot or adb.
this is a COPY/PASTE of my own post. the files i specify are the exact names, just search this section of X-DA for them. SEE BELOW.
i had the same problem with the "red screen of death" as well. i found that if i installed the "Minimal ADB and Fastboot" and / OR (i did the minimal first.... ) KFHD_SRTv1.3.5 and RUN THE APP FIRST, then when it says "waiting for device" you then plug in the ALREADY OFF tablet it then WORKS!! says "fastboot mode" on the tablet. and it is listed in device manager also.
i got BOTH apps here at this board in this section.
WARNING: i run windows XP with all updates as of 10-31-2017 (pm me for info, 2 lines of text!! ) . NEWER windows versions have "permission issues". fixes are posted in multiple topics here in the Amazon 7" Kindle Fire HD, 8.9" Kindle Fire HD, Kindle Fire 2 section. READ THEM!!
just make sure you do
fastboot -i 0x1949 getvar product
in the CMD before you boot your device.
I made mistake of booting device then entering command prompt and couldn't get anywhere.
I also tried different usb ports.
also updated drivers on usb ports.
I used iobit driver booster 5 today and scan/installed outdated drivers. Maybe that helped.
plugging usb I noticed windows recognize something with word jem in it when I turned on device.
turned off tablet and retried and I got into fastboot.
again make sure fastboot -i 0x1949 getvar product is active in CMD before turning on tablet
