Deleting files from the system folder only affects the current rom(or as you call it, operating system) and doesn't affect ADB or the TWRP recovery program. You can use TWRP to install a new rom, even the stock Kindle rom.
I can't post links, so search google for "kindle fire software update" and you should find amazon's page to download the latest stock rom for the kindle fire. Rename the file to update.zip and transfer it to the storage on your kindle. You can then use TWRP to select the zip file and re-install the stock kindle rom. This WILL break your root, so use the Kindle Fire utility that's linked in the development forum if you want to re-root your kindle.
If you don't have TWRP installed, try using the Kindle Fire Utility (in the development forum) to install TWRP or recover your kindle fire. I hope this helps!

TWRP is the recovery program that you can boot into before the rom loads. You can use the Kindle Fire Utility to install TWRP. If the kindle fire utility isn't working, you can try installing TWRP manually, but you will also need to install FireFireFire, which is the boot loader that replaces the stock kindle loader and allows you to boot into TWRP.
The most important thing is to have ADB access. If you can plug the kindle fire into your PC and get ADB working, you can fix pretty much anything.

How i can be sure that adb is working?

download the latest kfu from here:
http://forum.xda-developers.com/showthread.php?t=1399889
extract to c:\ and rename "kindle fire utility" to "kfu"
cd to c:\kfu and run "install_drivers.bat"
cd to c:\kfu\tools and type:
"adb devices" - get a response ?
"fastboot devices" - get a respose ?
you should get a response from one of the commands

I have to mention when in b63 post where your in the tools folder it easier to right click inside that folder in an empty space within it, and then press the keyboard's shift key for an option from the right clicked dropdown to open a command prompt window right there. Then type adb devices followed by enter key. Optimum would be a device ##000000000 sorta output in that tiny window , whereas then you could close it and click run in the kindle fire utility from the download. You can see more options to root your device to here with "status info".

Same problem

>>> Hi, I have the same problem here. I accidentally deleted my rooted KF system with no rom saved on my KF (I'm a noob). Now, I did the steps you mentioned above.
This is what I have:
-When I typed ad devices it says "list of devices attached :15FE000600000001"
-Got nothing when typed "fastboot devices.
-On KFU it says" adb statusnline', "boot status:unknown".
-I can't install the Fastboot mode on the KF because it stays on waiting for device.
-My pc recognizes the Kindle as a device on the Device Manager, but I can't explore it because it doesn't show up on My Computer.
-I have already unistalled, deleted, re-install the drivers many times. The one that comes with KFU only makes the adb status go offline. The only driver that makes it show on the computer is the one I get when I connect the KF to the computer and let it download a driver by itself.
Please tell me, what can I do to make it show up so I can paste the rom on the device.

You're getting confused with how adb and fastboot work. I suggest reading this to get a better understanding.

Thanks, I have read it like 3 times, it's just a little confusing for someone dealing with rooting for the first time. What I get is that I need to get the KF come up on Windows so I can paste the rom into the KF and that the KF needs to be in fastboot to install the rom.
Anyway, now the Kindle shows up on KFU as "online" and the bootmode is "4000", but still nothing comes up on the explorer. Twrp is installed and I'm able to load it, but I did not make a Backup. How can I install the system again?

If twrp is installed when you boot into it click on mount, then click mount usb, this is the only way it's going to show up as a mass storage device on your pc so that you can transfer a rom over to it.

Put both zips on your sdcard in zip form, wipe factory/data reset, wipe cache, wipe dalvik, wipe system, flash rom zip, flash gapps zip, reboot then system if prompted.

Thank you so much!!! :laugh:
I have done what you told me and my Kindle is now working. It's already downloading my files from the cloud.

Kindle Fire. Device Manager Sees but Kindle Fire Utility Doesn't

My Kindle was rooted but I decided to try my hand at installing a custom ROM. However, the ROM I tried would not work and the screen stayed black. However, thanks to TWRP I could install Kindle from Amazon again. The installation went thru smoothly, or so I thought. Now, when I boot the Kindle, I see the Kindle Fire Logo and it stays there. The Computer can see the Kindle as an Android device, Android Composite Device. But Kindle Fire Utility cannot see it so I could try and re-install it again. Any suggestions?

Lacking information, so I'll just fill the voids with assumptions.
I *assume* you didn't wipe cache, dalvik-cache and most important when switching from a ROM to another, Factory Reset - this is the reason said custom ROM wouldn't work, and the reason flashing back update.zip (as you said you installed it, rather than restoring a backup) caused your KF to get stuck in a semi brick.
The most important question here is, do you have FFF installed?
If you do, fixing this is trivial. Just get into TWRP from FFF, wipe cache, dalvik-cache and factory reset and then install whatever ROM you'd like to try or use.
If you don't have FFF installed, then your solutions are to either get a factory cable (recommended) or to crack open the case and do the USB pin short trick. From there you can use fastboot to install FFF and boot into TWRP.
Alternatively, you can try "fastboot getvar product" or "adb shell idme bootmode 5001" to see if you get lucky.

i have similar problem ......please need help
After successfully rooting kf with kfu and making a backup ... I did factory reset and flashed a custom rom ... now kindle is stuck on " kindle fire" logo and just keeps flashing and rebooting . My computer recognizes it as android phone ( android adb ) and kfu does too but only for a couple of seconds . During those few seconds I try recovery ... fast boot ...normal boot... n none seem to work . Kf just reboots n returns to boot loop . Any advice is appreciated .. thanks

What colour is the "kindle fire" logo when you turn on your KF?

Force Kindle into Fastboot
Ok, so I have finally got my Kindle to turn on, using the USB Short Trick. Now my only question is about getting the Kindle to boot into fastboot mode so I can re-format the sdcard partition and finally load a new ROM. I have tried several different commands and they all seem to miss the window of opportunity to start the kindle in fastboot mode. Is there any way, short of a factory cable, that one can make the kindle start in fastboot mode?

Not fastboot get var

fastboot getvar product doesn't seem to do the trick. The kindle seems to be in fastboot mode but the adb shell cannot access the device.

The problem is that you don't have the fastboot drivers installed (also, ADB will not work while fastboot is active) - Windows is painfully slow at detecting a device and installing its drivers, so by the time it even notices anything, the fastboot window is already over.
To solve this, use firekit: http://forum.xda-developers.com/showthread.php?t=1430038
The script that will probably suit your needs the most is usb_install_fff_twrp.

I have TWRP and FFF installed. However, upon booting into TWRP, the sdcard partition cannot be mounted, to the Kindle that is, and as such, I cannot mount the sdcard to the computer. When I researched this some more, I found that I can fix this by using a command via adb shell. The guide instructed using fastboot to achieve this. When would be the best time to use adb shell?

What's the output of partitions.txt? (type the following from TWRP)
adb shell parted /dev/block/mmcblk0 p > partitions.txt

Can't use adb

The problem at hand is using adb. I can never time it exactly right to open adb. I always get an "error: device not found". Windows even recognizes that Android ADB Interface is plugged in.

Okay, things are getting awfully confusing here.
What exactly is it that you can do and that you cannot do?
For example, are FFF and TWRP functional?

GOT IT!
Thank you! I finally figured out that the wrong driver had reinstalled and that was causing my computer to not be able to use adb shell. I fixed that and voila, I am now running CM9. Thanks again!

Kindle Fire stuck in TWRP boot loop, wont mount, not recognized.

I foolishly let someone try to root my Kindle Fire, and now it is stuck in what seems to be the TWRP boot loop (the kindle fire is blue and white). If I leave it alone unplugged it will occasionally continue to the Kindle Fire orange and white screen but will not go any farther. From the Blue/white screen I can hit the power button to enter the boot menu where I get Normal Boot, Recovery, and Reset Boot Mode. I can enter TWRP recovery menus, but otherwise it just keeps rebooting. Once in the TWRP recovery screen I can only navigate for a short time before it locks up and I have to reboot by holding the power button in. The sd card will not mount, and they did not backup anything before they started messing with the os. Ive tried the Kindle Fire utility but it says device not found. The Kindle showed up in my device manager as Other-Kindle before I installed the android drivers mentioned in another thread, and now it is under Android Phone- Android ADB Interface. It doesnt show up in My Computer at all. I've read about the factory cable but cant find on in the US so it would take 2 weeks to get here from China. Any suggestions on how to fix this, or do I now have a $200 paperweight? Thanks in advance.

Maybe go into twrp and do a factory reset. Can you get to that menu? Click wipe and then factory reset.

I've tried the factory reset but it seems to have no effect on it. How do I do the adb push? I've tried using the command prompt to run some of the commands on other threads but I'm not doing something right. I always get an 'adb' is not recognized as an internal or external command, operable program or batch file error.
I'll apologize now for my stupidity on this one- I have never worked with android software before this.
The kindle fire utility reads:
ADB status: Offline
Boot Status: Unknown
I can get it to boot in normal and recovery mode, but each time I try to boot in Fastboot I get an error message 'Oops... something went wrong. We are unable to locate your Kindle Fire. Make sure it is plugged in and powered on.' The Kindle shows up in Device Manager under Android Phone as Android ADB Interface
When using the twrp, anything that involves writing to or wiping the sd card receives this error E:failed to mount /sdcard (invalid argument)
I'd appreciate any help I can get. I'm at a standstill on this one.

im in the same position you can open it as a USB by selecting mount in TWRP and selecting mount USB Storage

do you have drivers / ADB on your computer ?
I did manage to get my kindle go into a recovery boot loop by doing the root procedure for the original 6.3 original Amazon ROM while my kindle had the 6.2 ROM . After i realized that the root procedure (intended for ver 6.3) didn't work for me, I had to try the procedure for rooting ver. 6.2.
It worked but after a couple of resets, the tablet went into a recovery boot loop.
what i did was to use ADB comands:
enter windows - > start command prompt (start - > run -> cmd)
check if kindle is connected: adb devices
if the device is found then use:
adb shell
su
idme bootmode 4000
exit

Hi all, I'm having a problem with my Kindle Fire. It is automatically booting into TWRP no matter what I do.
I have wiped everything, and installed the stock ROM, and when I reboot it just goes back to TWRP.
There is always a message of *verifying file system and *verifying partition. I can mount it and move files via USB.
In the fire utility it reads
ADB Status: Online
Boot Status: Unknown
If I try to change the bootmode it comes back waiting for device. I then got into the command line.
Doing "adb devices" shows it as being in recovery. I can reboot it from here, but goes right back to twrp.
I tried to do the adb shell--> su--> idme bootmode 4000
but after I do the shell it comes back that "su" isn't valid. I'm assuming I am doing something wrong, but I can't
for the life of me figure it out...any suggestions? Thanks in advance!

At startup hold thepower button untill you see the bootmenu come up and select "normal boot"

On the Kindle itself you mean? There is no bootmenu. I get the Kindle Fire (Orange) text, then goes straight to twrp, and if I do normal reboot from there, just straight back to twrp.

Tried it, no go.

This is what I get in the command line

The "<[6n" is likely the result of pressing the up or down arrow with number lock turned off and it is causing the command to be unrecognized.

Regardless, there's no need to use the "adb shell su -c..." command to get into fastboot. Instead use Pokey9000's bootmode binary "fbmode".

As you can see, the "adb shell" command is successful because of the change in the prompt.
~ # <-indicates the shell is working and active, so the actual /path of adb is irrelavent.

The TWRP.img file that comes with KFU is not TWRP. If I had to guess, it probably uses wget to download the file, for legal reasons? Maybe? Who knows? Replacing it with one downloaded from the TWRP website would probably be the easiest route.

You're going to have to clarify that a bit. Stuck where? The Kindle Fire screen? If so what does it look like?

The situation changes.
I dunno ecxactly i did, but my KF begins to stuck in the KF logo Screen, not anymore on loop triangles and windows begin to see my device.
So I tried the fastboot commands, but choose wrong:
fastboot -i 0x1949 oem idme bootmode 4000
and now my KF stuck in triangles loop again and the windows can't se him anyomre.

Kindle Fire wrote on White and Orange.
But don't stuck there, after the logo disapear the triangles begin to turn in loop.

Try to pay attention. You are in normal bootmode, with a corrupt file system caused by CWM. When the device is "stuck" at the boot logo it is in fastboot. Fastboot mode is needed to install TWRP and a host of other activities. All of this you would understand if you had read the Kindle Fire for Beginners guide stickied at the top of the Kindle Fire General forum. You would have been directed to that page if you had read the sticky at the top of this forum, labeled "Before Asking For Troubleshooting Help...". With the exception of CWM acting up (arguably), these are the most basic of Kindle Fire problems and it is a waste of time for people to have to go over them constantly, and unecessarily.

As I said before, that put you in normal bootmode. And, as it is said in the KFFB, you can only issue adb commands in normal mode. Issue the adb command to change the bootmode to fastboot (4002) or recovery (5001).
[Edit:]Use your command line to change the bootmode. If your computer won't detect the device for adb, there is a problem with the device drivers (also covered in the KFFB) and need to be reinstalled.

Yeah, I undestand that. The problem is that I don't know what I exactly donne to KF acept my commands. The only thing i've donne for sure is that I change the USB port, but I tryed again with no sucess.

I am stuck also at the Boot Triangles in loop - I am having the exact same problems as you are Reinaque, so just know your not the only one.
I have tried all of the different tools, but I am still stuck in the CM10 boot logo. Also I am stuck on "Waiting for device". My kindle is recognized by my computer on 4000 boot mode through KFU.... It won't allow me to write any commands through ADB... Stuck with you!
EDIT
It will not for the life of it let me get into fastboot!

Well, I don't know what to do anymore.
I tryed with another PC, installed the correct drivers and try almost every fastboot command with no sucess, the KF still don't aceppt the commands.
I will try something with firekit.
Damm, I really think that I lost my new KF =[

[Q] Bricked KF2 - no OS, fastboot & TWRP available

I've read through hundreds of similar threads and haven't been able to find a solution - I'll gladly give up my firstborn (and/or make a paypal donation) to anyone who is able to help solve my issue!!
From my research, I seem to have no OS installed on the Kindle, and as far as I can tell, I'm booting into fastboot mode (screen hangs on the blue/white Kindle Fire logo, screen does not ever dim). I AM able to access TWRP Recovery, but don't have any backup to load from, am unable to successfully flash the ROM that I have saved to my SD card. My device manager recognizes the Kindle as a Kindle Fire (Android ADB Interface), no yellow triangles. Typing ADB Devices into Command Prompt gets me: [device number ] offline. Typing fastboot devices into Command Prompt gets me nothing (blank line).
Background/How I 'Bricked' It: I have a Kindle Fire 2 and was able to successfully unroot/flash Cyanogenmod 10 onto it. Worked perfectly for about 6 months, when I decided that it would be a good idea to flash back to stock so that I could give it to a relative. I have TWRP 2.3.3.0, so I used a guide on xda to do the following:
I used a guide from xda and followed these instructions
-Download latest KF2 stock software from amazon. Re-name the file to update.zip
-Moved it to the root of the SD card
-Booted in to TWRP
-Factory Wipe/Restore
-Wiped Cache
-Wiped Dalvik Cache
-Wiped System
-Installed the "update.zip"
-Wiped cache/dalvik again
-Rebooted
Unfortunately, wiping the system seems to have wiped the CM10 OS (ROM) that I had installed, and there was a failure in installing the amazon stock:
Installing '/sdcard/download/update.zip...
assert failed: is_substring ("Otter2 , file_getstring("/proc/product_name"))
E: Error in /sdcard/download/update.zip
(Status 7)
Error flashing zip '/sdcard/download/update.zip'
Updating partition details...
Trying to reboot the system from TWRP results in a message that states: "No OS installed! Are you sure you wish to reboot?"
Investigating using ADB: So it looks like I have no OS on the Kindle Fire 2. This seems to be a problem because without an OS, I am unable to use adb (from what I've read, no OS = no way to accept/authenticate the computer RSA fingerprint to whitelist the kindle and allow adb to function). Trying to use KFU, KFFirstAide, or the Kindle UnBrick Utility results in Error: Device offline or Error: Device not found types of messages (I am assuming due to the fact that I can't "turn" adb on by accepting the RSA fingerprint prompt)
What does Device Manager tell me? My computer can 'see' the Kindle Fire in device manager [as I stated earlier: My device manager recognizes the Kindle as a Kindle Fire (Android ADB Interface), no yellow triangles] but going to My Computer and looking under mass storage devices, the computer doesn't seem to recognize the device as a USB storage device, which is a problem because I can't drag/drop or push/pull files to the SD card so I can't try to flash anything *other* than the original file that failed.
Fastboot Mode...? From what I can tell (http://forum.xda-developers.com/showthread.php?t=1668159), my device is in fastboot mode. My Kindle screen hangs on the blue/white Kindle Fire logo screen, which from what I understand is hashcode's bootloader/fastboot screen. However, when I look at the Hardware IDs in the device manager, it tells me that my hardware IDs are:
USB\VID_1949&PID_0006&REV_0216
USB\VID_1949&PID_0006
So...my kindle seems to be stuck on the blue/white fastboot screen, but register on my computer as the stock kindle fastboot? I'm not really sure what's going on there, and couldn't find too many people with the same discrepancy that I have...
I tried plugging in my cord (making sure to use a USB 2.0 port), going into Command Prompt and using some fastboot commands. (ie: fastboot flash bootloader \path\update.zip) but all I get is a <waiting for device> for a LONG time. As in, a few hours. Some basic googling/investigation seems to indicate that I don't have fastboot drivers installed, OR that I wasn't running fastboot in an 'elevated mode' but I haven't been able to find too many details about how to fix those, IF that is the problem.
TWRP 2.3.3.0: I can get into TWRP recovery just fine, although I can't seem to figure out how to get files onto my device. So I've tried re-installing the original update.zip file that failed the first time several times, with no success. trying to 'Mount' the device doesn't seem to do anything (at least, my computer doesn't see the device as USB storage regardless of whether it's mounted or not) I tried using Advanced --> ADB Sideload, but trying to send the file in Command Prompt using the adb sideload <filename> command just gets me an Error: Device not Found message. I thought maybe I could try Advanced --> Terminal Command, but have no idea how to do that or what it does, and most sites are very vague about the step-by-step details, so I didn't really touch it.
Not sure if this is relevant or not, but when my KF2 is plugged into (attached) to my computer with the cord and is in TWRP, device manager shows the device under 'Other Devices' --> Amazon Kindle Fire2, and there is a yellow triangle on it. Not sure why...going back to 'fastboot' mode gets rid of yellow triangles and is recognized as a Kindle Fire again.
At this point - I'm pretty much stumped and have (hopefully) demonstrated that I've done my best to do my own research/read through threads/done due diligence. Is there anyone out there that might have any suggestions? Or do I now have a very large paperweight?
ANY input/suggestions/encouragement is welcome! I absolutely and sincerely appreciate your time in reading through this thread and trying to help noobs like me!

Use fast boot mode to recover to stock: http://forum.xda-developers.com/showthread.php?t=2096888
Or
If you have access to twrp. Use the ADb sideload feature to push CyanogenMod or another ROM over.
One thing though- if you can boot into TWRP you didn't wipe the system partition. Twrp for kf2 requires a file named stack to be there.

...tried those, but maybe am doing them incorrectly?

Trying to use the ADB sideload feature to push CM or another ROM over doesn't seem to be working for me (unless I'm doing it wrong?)
I tried using Advanced --> ADB Sideload, but trying to send the file in Command Prompt using the "adb sideload C:\users\Name\update.zip command just gets me an Error: Device not Found message". Could I be using the command incorrectly?
Trying to use any fastboot command in Windows Command Prompt results in <waiting for device> to hang for hours, with no changes to command prompt and no changes to the kindle (still sits at the blue/white boot logo).

Ah. Sorry. Missed that in the OP.
Sounds like you probably need the drivers installed.

Are there difference drivers for fastboot and adb? I don't get a 'yellow triangle' and my device manager identifies the device as a Kindle Fire [Android ADB Interface], so I thought I was okay.
Should I be looking for fastboot drivers?
And btw, thanks so much for your willingness to help and input!

ME TOO
Just purchased a KF from someone...thay had rooted it...I tried to unroot...got stuck...now mine is doing the same as yours. I hope someone has a fix for you as I too have a large paperweight.

tessa33,
I just sent you a response. Call me at 707-774-5923 when you have a moment.

Solution?
I figured I could post in this thread before staring my own because I am having a very similar issue trying to revert my Kindle Fire 2 back to stock from cyanogen so I can sell it. I downloaded the official software from Amazon but every time I try to flash it through TWRP I get the exact same error you were getting. Did anyone ever figure out how to resolve the issue for you?

Had the same problem, so I chatted with an Amazon associate, told him I turned it on one day and it showed the grey triangle and he sent me a new Kindle Fire 2nd Gen for free. Try that...
