[Q] KFU Driver Error - Kindle Fire Q&A, Help & Troubleshooting

Tried to use KFU for the first time and ran into the Google Inc USB driver unsigned failure when I ran the driver utility.
What do I do to fix that?
TIA

Did you try uninstalling and reinstalling the drivers?

The drivers never installed so I don't think there was anything to install.
How would I check/do that?

Waiting for device
My Kindle Fire is also having problems. It is rooted and was running ICS for some time. I tried to make some changes, installing another ROM, and now it won't boot into the ROM or recovery. I get the original "Kindle Fire" splash for a few seconds and then nothing. I've tried the KFU but it just says "Waiting for device". It won't connect. I've tried to reinstall the drivers, but that hasn't helped. Any ideas?

I just ended up starting the install for KFU on a different PC and the drivers installed fine.
I didn't end up going any further with the root because I'm catching up on some Arrested Development episodes using Amazon Prime while I have the free month.
I may go ahead and do it since I could presumably unroot to watch the vids but I've heard of that not working for some.

What I had to do to get my computer to recognize my Kindle Fire is install the drivers with the Kindle not plugged into the computer. After the drivers installed I connected it and it worked perfectly. Not sure if this will help but thought I would put it out there.

Didn't work
Thanks for the tip. It didn't help though. Appreciate your help.

Root Issues.

My brother just attempted to root his kindle with the kfu. He rooted his kindle, and he changed his wallpaper with kfu as well. After this, he put root check on his kindle after some issues with mounting as read write using root explorer. It turns out, his kindle was NOT rooted, after changing the wallpaper witht kfu, which NEEDS root access, and even after redoing the process of installing another root on his kindle.
What should he do? My kindle was rooted manually, but since kfu came out, no manual instructions are really available. If we have to root manually, what commands do i need to use and whatnot?
Thank you for your time. Any help is greatly appreciated.

If you want to keep the stock look then you can flash MoDaCo. Otherwise there are plenty of ICS and CM7 roms you can use.

I'm having problems getting my computer to recognize the kindle fire in fastboot mode. i have tried to root my device for around a week.
also i am getting a screen on kfu that says,
Fastboot uses a different device than ADB. You should check device manager for 'Kindle" or "Amazon"
If you see it, rerun the driver installer that came packaged with KFU
Installing FFF
<waiting for device>
Then i go to device manger and i see Kindle. after that i rerun the driver install that came packaged with kfu.
I get this error message
Cannot complete the device driver installation wizard. errors were encountered while installing the software for your devices. See the status column for more details
Sometimes it helps to run this wizard again. If that doesn't work, contact your device vendor

i run the driver installer and it still doesnt work. i've already changed the settings on my computer so it can install unsigned drivers.
I have no idea what to do.

Installing the drivers in XP is really weird. If you have access to a Vista or 7 PC that would be the best.

On your EeePC look under devices and find a device called "Android Phone", "Kindle Fire" or something to that effect that is using the WinUSB drivers. Uninstall it and you will be able to reinstall the drivers from the KFU/Drivers folder.

Have I Bricked My Kindle Fire??

Was attempting to re-root my Fire with KFU, however KFU chose to install TWRP first which I think prevented me from ever achieving root. So as instructed to reinstate my stock Fire out of the box I flashed the update file as I had before to unroot it which worked perfectly. However, now I am stuck at the Kindle Fire boot screen and no TWRP to boot into recovery. Any help would be greatly appreciated.

Reverting to stock, does just that. It reverts your device to the state it was in when it came out of the box, and is completely unnecessary. TRWP does not prevent "root", it simply aids in the "rooting" process, which is unnecessary in itself.
Put your device in fastboot (very likely it already is), reinstall TWRP, install FFF, wipe partitions, and flash a ROM. Problem solved.
IF any of this is foreign to you, you should do a little research before continuing and getting yourself into more trouble.

What I think is that you are in a different bootmode, but your kindle is not showing up as a adb device. Have you tried hard resetting? But remember, unplug the USB cable, then hold the power button for 20 seconds, power back up, and then see if you can see the kindle appearing in KFU
Edit: I agree with soupmagnet. If my suggestion doesn't work then use the links he posted and follow his method

Forget about rooting it for a second. It is unnecessary. Install a custom ROM and be done with it.

[Q] G-Apps on a new JB ROM

First of all, I'd like to thank you all that make this community so valuable to us. I read the forum since I got my KF, around 6 months ago, and all the tutorials are very well detailed.
Today I tried to install a new ROM on my Kindle for the first time. It all went well, and I successfully installed the stock Jelly Bean from Hashcode. But the problem now is: I don't know how to install the GApps on it.
I'm trying to use the ADB and Kindle Fire Utility but it doesn't find the device.
Anyone of you guys could give me a hand with that problem?
Thanks
Are you using twrp? You flash gapps onto it the same way you flash a Rom. Boot into twrp, go to install, locate the directory where you have the gapps.zip file stored and click on it, flash it. Then wipe cache/ and dalvik cache and reboot.

I think the problem is with the adp drivers...I can not find my device so I can restart it with TWRP.
Ok but if you have fire fire fire and twrp installed already you should be able to bout into twrp by pushing the power button repeatedly during startup until it shows you voting into recovery mode.
Make sure you have the correct drivers installed,I believe the kf should show up as composite adb interface device on your pc with the right drivers. Someone else might be able to help you more but really the easiest way to flash gapps is to do it through twrp the exact same way you flash the new Rom minus the system wipe and factory reset.
Your device is a first gen kindle I assume?

Yes, it is a first gen Kindle.
I'm trying to boot to TWRP pressing the power button during startup but either I'm doing it wrong or something went bad after I installed the ROM.
I also tried to install the ADB driver in another computer but after I connect the kindle the PC recognizes it only as "Amazon Kindle Fire", and not the ADB interface.
I don't know what to do. But thanks for your help!
Try using the pc that is recognizing it as a kindle fire, uninstall the kindle fire drivers through device manager and then install the Google adb drivers, then hook the kindle back up to it via usb and see if it shows up correctly then?
Is your boot screen showing kindle fire in blue and white or the stock orange or something else?

Ok.......what type of computer are you using.....that info would be helpful for those who have more knowledge
Also, what are you trying to accomplish.
Having the same issue. Tried on three laptops, two with Windows 7 and one with Windows 8. One of the laptops didn't have any ADB drivers installed perviously. Tried the drivers included in KFU, the Amazon drivers in the Android SDK, as well as a modified Google WinUSB. Getting Code 43 upon plugging it in. If I manually pick Kindle Fire from the driver list, I then encounter Code 10. Tried factory resetting the Kindle Fire. The device functions 100% other than this issue so I am very confused what the problem is. It is on the latest version,
Same Prob!
Trying to flash a ROM to my "bricked" kindle using TWRP, but my computer won't recognize my kindle at all, not even in KFU, should I try a different computer?
same issue - just rooted and flashed today, and after installing CM10.1 Jelly Bean 4.2.2, none of my computers (1 Win8, 1 Win7) will recognize it in device manager. i really don't know what to do...
as a workaround, is there another way to transfer a .apk file to the kindle without connecting to a computer? I'm just trying to get Google Play so I can operate it independently of a computer...
to Rocket Nine and further: what TWRP version are you running? what were you running before this happened? what ROM are you currently running?
siudan1977: there is already Google Play on your device, given that you also flashed a Gapps. if you didn't, download one from the place that your ROM came from, but on your kindle. not your computer. then boot into TWRP, and flash the Gapps package you downloaded.

Thanks so much for the response! Downloaded Gapps on my kindle, but can't boot to TWRP now - other videos showed the way to cycle through options with the power button, but that doesn't show up for me - goes straight from the kindle fire logo (no text at bottom) to the CyanogenMod loading screen. any ideas what might be going on?

finds twrp.img, and downloads fff.bin. Then the kindle reboots, KFU says "Installing FFF..." and <waiting for device>.
But then does nothing, even after I swipe the lock and go back into file transfer mode on the kindle.
Anything I try to do reports "couldn't write bp1, panic!" on KFU. I have another kindle that rooted fine, this one just refuses to.
Any ideas?

Yes, I actually had 2 of them that rooted fine. They are all KF HD 7" First Generation. This one just won't. I'm now working with the KF First Aide tool kit, and I now get SU: ACCESS DENIED or something like that. Communication with ADB is fine, there's a permission issue somewhere I can't figure out.

Awww crapola. Nevermind. All I knew was that both of them were on 6.3.3, so I thought that was what they've always been on. Bzzzzt. The one that was working still has the adw launcher installed, but it doesn't have root any more. So THAT'S why KFU doesn't work on this new one.
They are my girlfriend's kids' kindles, and I told her not to ever update them, but I guess this one was pushed out.
So.... how long until theres a root kit for 6.3.3?

Didn't brick it, but didn't work either. The apk installs just fine, but when I click the "make it rain" button that says the device will reboot, nothing happens. The device does not reboot, and is not rooted. I tried rebooting the kindle and trying again with the same result. I guess I now fit the definition of insanity.

And... tried V2 of towelroot this morning. Still no worky-worky.
Somebody get a straitjacket.
Old rooting methods not working yah...
What I have done -
1. fastboot using factory cable
2. install TWRP+FFF with KFU
3.flash modified pre-rooted ROM
If Amazon continues updating 1st gen, not sure there are lots of enthusiasts, who would continue rooting it. Thus decided to switch to alternative ROM. Well, stock is better for battery etc... etc... but as I do also have HDX and most of time use it, having stock ROM on 1st gen is not as crucial for me.
According to this post (and the post above^^), if you have a factory cable (special cable used to power on in bootloader mode), you can revert to a custom recovery and bootloader and then flash a 6.3.2 ROM. Problem then is avoiding another OTA.
