[Q] KFU Stuck trying to remove root checker.

I have been trying to reroot my Kindle Fire for some time now but recently when I try to run KFU it gets to the point where it installs TWRP but gets stuck in there trying to remove the root checker. The only way I can go back and actually use the kindle is by flashing the update.zip from the amazon website. Any help?

Were you actually successful in getting TWRP installed? Have you tried to access it?

It boots into TWRP while its rooting the Kindle. The problem is that it stays there and doesn't continue. TWRP is also missing some options and some text. I have to flash the update to gt out of TWRP

Download this and push it to your sdcard

It is a flashable version of TWRP that can be installed in recovery (this is to fix any potential bad installation of TWRP).
Reboot and access TWRP again.
Once in TWRP, enter the following code to remove the root check:
Code:
adb shell mv /system/bin/check_rooted /system/bin/check_rooted.bak
If you get an error message that says:
Code:
mv: can't rename '/system/bin/check_rooted': No such file or directory
You have nothing to worry about. It just means the "check_rooted" file does not exist.
While in TWRP, you can do whatever else you need to do to root your device or just flash a ROM (they're pre-rooted). If you do flash a ROM, be sure to wipe "system" and "factory reset" first. Otherwise you're looking at possibly needing a factory cable (or firekit) to fix the problem.

[Q] Terrible Kindle Fire (2nd gen) issue that can't be resolved

Hi guys I'm new here but not to rooting Android devices and such. I had a XDA account back in the Windows Mobile 6.5 days but I have no clue what happened to it so I just made a totally new account. I have searched for this issue top to bottom and I cannot find a solution.
So for about 3 weeks now I've been having this problem with the Kindle Fire I got for christmas. It's not bricked, but I tried to switch to the AOSP stock JellyBean 4.2.2_r1 ROM from CM10.1/SGT7 version9. When I did this the kindle seemed to booted up fine, and when the setup process was done I had no Navigation Bar or a Status Bar, also causing the installer to malfunction and give an infinite installing screen (forcing me to reboot due to there being no Navigation Bar.). I thought to myself "OK I'll just reinstall CM10 and everything will be normal." Nah. The same problem was experienced when I finished the setup after reinstalling CM10. So I tried flashing an earlier version of CM10. No dice.
When I switched ROMs I made sure I wiped everything from System to Devlik. Still having the same problem. I have twrp 2.3.3.0 atm and I noticed that when I boot into twrp, off deck it says "E:Unknown File System: 'datamedia' " in the log. I also noticed that when ever I format something it says "Using rm -rf on......" So I decided to go and disable this as it might be why I'm having such issues. I went to settings and tried to disable this option but it wont let me disable it (as in it wont let me deselect the "Use rm- rf instead of formating?" option.).
When this happened I decided to look for an update for twrp to fix this issue. When I found the update to 2.4.4.0, it's only apparently able to be installed via fastboot. I as of now do not have a fastboot cable, nor can I make one. I would buy one, but money is a bit short. This also brings me to my next issue that I have searched to no end for.
No matter what drivers I install for my kindle Fire, my computer asks to install new hardware when I plug my kindle in. This is just for USB mounting. I haven't even tried ADB drivers yet. I can't mount USB storage in android or twrp. Twrp says "E:Unable to locate volume information for USB storage mode." When I am able to finally get some good drivers installed and working, only 30 seconds pass before they stop working and I'm not able to do anything. This forces me to transfer all files in ES file explorer over Wifi (which has to be installed manually by downloading the apk and copying it to the system/app folder and rebooting.).
After all this occurred I decided to go back to the stock Amazon OS and unroot to start from dirt. I went to Amazon's website and downloaded the 10.3.1 update for Kindle Fire second gen. It downloaded in .bin format so I just renamed the file update.zip and copied it to the root of the SDcard. After all that I booted into twrp and tried to install the ROM and it gave me this:
Installing '/sdcard/update.zip'
Checking for MD5 file......
Skipping MD5 check: no MD5 file found.
assert failed: is_substring("Otter2", file_getstring("/proc.product_name"))
E:Error in /sdcard/update.zip
(Status 7)
Error flashing zip 'sdcard/update.zip'
Udating partition details...
Once this happened I promptly searched the error on google. There was nothing exactly pertaining to this issue, so I searched the error in general and found that it happens a lot with ICS roms. They were all however errors that dealt with the system name being wrong but that's not exactly my problem is it? I even tried modifying the Update-script but that only gave me an infinite blue kindle logo screen.
If anyone can help me it would be greatly appreciated. This is my first run with any kind of tablet. I would like know how I can restore it back to the stock Amazon OS. If so how, I feel like I have tried everything.

Do you have a fastboot cable? First, I recommend that you get one.
Then, your best bet is to completely restore from stock and start over using the kindle fire restore utility in the development section.

The update.zip isn't going to flash for you because of the asserts set in the updater script. Basically, once you flashed cyanogen your device no longer identified itself the same way.
The problem you have with formatting isn't a bug. You would be screwed if TWRP let you uncheck the box.
The E: thing is normal and not an issue..

Alright so I need a fastboot cable, and to restore to factory settings. I'm guessing TWRP would be gone when I do this right? Also Thank you. I think I'm going to stick to Amazon's OS for a while untill I can figure out the drivers.

Yes. Twrp will be gone.

I think the fact that CM10 changes the device name is the reason why I have so many driver problems. So I'm going to stick to Stock Amazon untill CM10 is on it's final release. Is there any way to change the device name back to the original? The only difference is a space between the names is Amazon Kindle Fire 2 and Amazon Kindle Fire2(on CM10).

The device name change doesn't effect the drivers. That only effects the update script. Once you are stock the device name will revert back
Make sure you have uninstalled all previous drivers for the kf.
Then make sure you used the drivers I suggest at the end of that thread.
99% of all the issues I see for this device are just driver problems.

Are you sure that it doesn't? Because as soon as I installed CM10 all my drivers were suddenly incompatible.

So you are probably using the Google device drivers from another phone or windows update or such. Cm10 drivers seem to work out of the box, but of you want both to work use my method.
The name change isn't what effects the drivers, it's the operating system that effects the drivers needed
When I first set up my system I couldn't access the devices USB Mount on stock but cm was OK. I went back and followed my own instructions... Now adb, fast boot and USB mounting works from both oses

[Q] Unable to install stock ROM on Kindle Fire

Hi.So I used to have Cyanogenmod installed on my rooted Kindle Fire, along with FFF and TWRP recovery. I was not satisfied with the performance of Cyangogenmod, so I wanted to install the Stock Amazon ROM back onto the Fire. First, I booted into TWRP, and erased everything with the 'wipe' option (might not have been a good idea). I have downloaded the Amazon ROM from here: http://kindle-fire-updates.s3.amazonaws.com/update-kindle-6.3_D01E_4019920.bin, and renamed the file 'update.zip'. I mount the Fire, and drag over the update.zip, and then I go to 'install' in TWRP and select the update.zip, but after I start it, the install just fails, seconds after it's started. There are a couple errors, such as "Error executing updater binary in zip '/sdcard/update.zip'". I have ADB installed, and Kindle Fire Utility, which detects the device as 'online', boot status 4000. I have tried install COTR recovery with KFU, but it hangs at 'Activating Fastboot (4002)'. I would really appreciate any help with this, because it would really suck if it turns out that I bricked my Fire. Thanks!

I am trying to go back to stock because I am now having TONS of trouble keeping files running without them crashing. Also, every time I try to read a book now, the Kindle app crashes before it ever really opens. I have tried uninstalling that app, then reinstalling even. No help at all.
Any help in this matter would be HUGELY APPRECIATED!!!!

If a flash does not complete, it has to be a bad download. Get the file again and push it to the sdcard via twrp. But if you are having trouble, why flash factory? If it is some corruption, flash a rom. Kindle store and reader fail because of the app, generally. Notice my device says Nexus 7? That is how to fool the kindle apps on a fully functioning kindle fire.

I have redownloaded the flash from Amazon at least five times, all with the same results.
As far as pushing it to the sdcard via twrp, I guess I for one don't know how to do that.
As to why I would want to go back to factory with it, I guess for me, it is what I prefer.
Thank you for answering though. I do appreciate it.

Same here, fixed!

I had the same problem. I ended up reverting back to TWRP 2.2.2.1, which can read the update.zip properly.
I downloaded the older version from techerrata dot com --> twrp2 -->blaze-->openrecovery-twrp-2.2.2.1-blaze.img
I then used my fastboot cable and ran fastboot -i 0x1949 boot openrecovery-twrp-2.2.2.1-blaze.img.
This allowed me to run the older twrp, clear out my /system, and get back to stock.

I just get stuck at < waiting for device > on my command prompt. Where am I supposed to open the cmd?

I just wanted to say, after several hours of searching through Google and messing with my Kindle, this thread finally helped me fix it.
My biggest issue was, I was unable to flash any thing, even the twrp. So what I had to do was this,
I googled the twrp 2.2.2.1 blaze img as mentioned here, then I renamed it to twrp.img and put it in the folder inside KFU -> Recovery
My other issue was with my Kindle being stuck at the Boot Logo saying, "Booting" and I noticed through trial and error, before the kindle goes to try to boot (When you can select Normal, Recovery, Reset Boot) that if I kept pressing the power button to cycle through the options, I could keep the Kindle in a Fastboot mode so I could use the KFU to install the TWRP 2.2.2.1
After that it was simple, booted into twrp, mounted the drive and stuck the Stock Rom from Amazon on there and installed it.
So I really just wanted to say thank you to this thread and hopefully I can contribute a small bit to someone if they have my issue.

Having the exact same issue when using KFU it just hangs there on activating fast boot

[Q] KF issues and what I have tried so far...

Hello.
I have a KF 1st generation. I had rooted it some time back and then un-rooted it (thought I did?) and haven't had an issue. This week it started loading up and freezing on the Kindle Fire orange and white logo. I am able to boot it to Recovery which gives me Cannibal Open Touch screen and options. I did try a few of the options but still the same end result. After coming here and reading around I found a thread and I followed the directions since the original poster and I seemed to have the same issue. There are the steps I followed:
Step 1) Download MoDaCo Rom/Any other ROM BUT NOT ANY KITKAT ROM(COTR can NOT flash KitKat)
Step 2) Transfer your ROM while in recovery
Step 3) Do a preflash wipe
Step 4) Do a factory reset
Step 5) Go to 'Install -> Install from SD Card -> Folder where you put your ROM
Step 6) Click Install without Backup
Step 7) Boot Android
I downloaded [ROM] 14 Jun Gr9 (6.3.1) - MoDaCo Custom ROM for the Kindle Fire and made it to Step 5 using the 'Zip Flashing' option but I can't seem to flash or sideload or any of those options. While the Kindle is plugged into the computer I hear the noise and when I find my Kindle it has a Yellow Triangle with a !. I looked at the Kindle and it tells me I have no drivers and I am not able to drag and drop any files. Also, not sure if it matters but I am no longer using the computer used to root the Kindle.

the rebooting is the new 6.3.3 update trying to install, but because you have custom bootloader/recovery install fails.
may need to install twrp recovery. but my prerooted 6.3.3 zip sbould install fine.

I have been trying to figure this out and searching but I can't seem to figure this out. I am uploading the screen I have on my KF and I don't know how to mount the file. I can't find a thread that will kind of walk me though it so if you know where I should go that would be great. I am uselessly pretty good with figuring things out so maybe I'm making this harder than it looks?

Victory!
First off TY for the time you took to get me to the finish line. :victory:
I will admit trying to mount was a nightmare. I couldn't figure out how to do it so after hours of playing around and trying to find anything to try I finally succeed by installing the Kindle Fire Unbrick Utility (again) and running KindleUnbrick.bat file and installing the TWRP that way. Once that worked (and believe me I didn't think it would work since I tried this a few times) and I yelled WOOT, I followed the rest of your directions from "In TWRP (Team Win Recovery Project) select Mount check sd card and tap mount USB Storage" and installed your prerooted 6.3.3 zip and finished off your directions and have myself my dear reading buddy back. I APPRECIATE deeply the time you took to get me back. :highfive:
I want to add for anyone who is looking though threads looking for help with the same issue. If you are trying to get the TWRP file on your Kindle download the Kindle Fire Unbrick Utility and then running the RUN file and follow the directions.

great, Glad I could help.
I have tried to use the Kindle Fire Unbrick Utility a few times, with little success.
I would only suggest it, if nothing else is working, but does work in some situations.

[Q] A real brick? Can not mount system

Hello all -
I have been toying with this gen 1 (maybe 2... not sure) off and on for about half a year now.
The device used to work great and was running stock OS. One day it just gave up the ghost. My daughter was using it and it would not start up into the OS. When starting the device, it would load the yellow Kindle Fire screen and just hang indefinitely.
Using a factory USB cable, I was able to use KFU and get TWRP loaded.
Within TWRP I can see the SD card (contains ".android" and "TWRP" folders) and even load files from the PC to the SD card.
When I go up levels, I can see what I think to be the OS directories, but none of them seem to contain any files.
One of the folders is named 'system' so I have a good feeling this is the OS.
However, I am not able to mount the system nor the data partitions within TWRP.
On my PC I can explore the device and I can see the SDcard perfectly fine, but no system or data.
What I would like to do is just reload the stock OS back on.
I have loaded the latest Amazon update to the SD card and tried to install it.
Near instantly, the TWRP screen says that it can't find directories and it fails/stops.
I have tried every button in TWRP for fixing permissions, wiped system, cache, etc. (everything cleared), resetting everything etc etc.
To no avail, I still can't get the system to mount.
I do encounter an error when fixing permissions as it fails every time. It says it can't fix permissions and wants me to try again after booting a ROM. (whatever that means?).
.
I have also tried using adb shell to force the device to reboot into fastload and then load the OS update.
I was able to get the latest TWRP loaded this way, but could not get the OS to go.... again, it can't find the directories.
Currently, when I start up the device I get a blue logo screen and can get into TWRP. If I go to boot normally, it continues to the stock yellow logo, dims, and freezes.

Also I dont think mounting system and data to pc from recovery actually works. Just drop a Rom on to your sdcard do a full wipe and flash it. Before you reboot select mount you dont have to be connected to pc make sure there are no checks in the boxes of system and data if so uncheck them then select reboot system.

I give this a try. I wasn't able to do the first part with resetting the partition tables so wend to where it gets set it into recovery mode and moved on.
Everything worked from adb shell.
I went back to the KF, mounted the SD card.
Downloaded a new update for the KF from Amazon and renamed it from bin to zip.
Copied it to the KF SDcard. Verified the KF was in bootmode 5000 and tried to install.
No dice - errors.
I tried downloading the update through KFU. Pushing that update through ADB to the SDcard. TWRP factory reset and tried install.
No dice - errors.
Skips MD5 check.and then rattles this out:
assert failed: getprop("ro.product.device") == "blaze" | |
E:unknown command [err_string]
getprop("ro.product.device") == "blaze" | |
E: unknown command [err_string]
E:Error executing updated binary in zip '/sdcard/update.zip'

If it's a kindle fire 2, it maybe bricked.
How is it listed in device manager?

if it is a kindle Fire 1, TRWP 2.2.2.1 or lower is needed to install a stock update.zip

just try my [2014][Pre-Rooted][Stock]System Version 6.3.3-Original Kindle Fire Only
with the twrp you have.
download update-kindle-prerooted.6.3.3.v1.zip
mount>sd card>check sd card>mount usb
copy update-kindle-prerooted.6.3.3.v1.zip to sd card
unmount sdcard
select install> select update-kindle-prerooted.6.3.3.v1.zip >swipe to confirm

I give this a try. I wasn't able to do the first part with resetting the partition tables so wend to where it gets set it into recovery mode and moved on.
Everything worked from adb shell.
I went back to the KF, mounted the SD card.
Downloaded a new update for the KF from Amazon and renamed it from bin to zip.
Copied it to the KF SDcard. Verified the KF was in bootmode 5000 and tried to install.

Your error is due to the fact that your trying to flash blaze with an otter recovery it's totally normal new recoveries don't like old updater scripts.
The updater script in sd_shadow 's zip is modified to avoid that error. When flashing stock use cannibal open touch recovery it will not give you this error just make sure you wipe cache, dalvik, data and system prior to flashing update.zip. It's not a good idea anyway wipes your recovery and bootloader anyway, I would choose to keep those intact.

So I've tried this 3 times now with no luck.
The first time I tried, I got through the TWRP text saying it was doing some stuff, doing more stuff, thanks to 2 people.
Then it went to the Teamwin screen and every few seconds that screen would blink. Eventually the screen went to sleep and pressed the power button once and the teamwin screen was still there.... so I left it alone for about 5 minutes.
After waiting, I held down the power button and restarted the KF.
Round 2.
Wiped everything and sent over a new copy of the ROM.
This time it got to the teamwin screen and after about 30 seconds of blinking, it went black - completely off. Seconds later the blinking teamwin screen came back in all of it's glory. After more blinking, the screen turned black, not off because pixels were still lit up, but black. Power button was blinking red very slowly. Waited... waited... held down the power button and restarted. Still operated with no OS booting up.
Round 3 - exactly like round 1.
Round 4 - Everything the same, but this time I noticed the lit black screen turned off and came back on. Then it just stays lit.... no power button color either.

OK back to how is it listed in device manager?
What version of twrp?

Device Manger has it listed as 'Android Phone' > 'Android Composite ADB Interface'
TWRP is 2.7.1.0 as your install instructions ask for (was 2.6.something-something before)

Are you verifying md5 checksums after downloading files?

When you enter recovery go to setting disable screen timeout that will save you some hassle.

Thanks - I had the slider adjusted, but totally overlooked the button for disable.
I downloaded COT
Cannibal Open Touch Recovery 2.1.3
for 600 X 1024.
I found the recovery and boot img files it needs from an unpacked update.
Does it really need CWM installed? Or will TWRP get the job done?

I'm pretty sure that is not the COTR you want.

If your gonna flash update.zip make sure it's not update.zip.zip cotr will flash it wipe everything except your sdcard first. If your gonna flash sd_shadow zip the twrp you are using will work.
This http://forum.xda-developers.com/showthread.php?t=2025793 Use kfu to download it fast boot to install or just select reboot bootloader and use kfu to send it.

download cotr.img for kindle fire 1 http://d-h.st/XWy

in command prompt
fastboot flash recovery cotr.img

Thanks! Got it on there. I tried it from KFU, but it didn't take. The img you provided worked!
That link for COT wasn't COTR and I got absolutely nowhere with it. Waste of time.

I believe that the link KFU used is dead.

Well...
windows no longer allows me to look at the SD card after changing over to COTR.
Same goes with KFU and ADB devices.
I verified the driver and SDK files are still edited correctly.
Device manager still sees when the KF is attached and I get the sound of connect and disconnecting from Windows.
In storage management I have tried everything.
So, I can't send over another 'update.zip' of Amazon image.
I still have the prerooted 6.3.3.zip on the SD - so I tried to install it.
COTR has a status bar fr the installation.
When it gets about 1/4 of the way, it errors saying it can't find some signatures. I get the option to continue anyway so I go ahead.
does stuff.
does more stuff.
- takes a long nap
Thanks 2 people.
- status bar goes to about 3/4 of the way and.... stops doing anything.
Round 2!
Same thing, but this time it made it. Install complete!
Only thing different is that I unplugged from the PC while it was taking it's nap after doing more stuff.
KF is now looking for a WiFi network.
THANK YOU BOTH FOR THE HELP!!!! :good::good::good:
