Restore to original ROM with factory cable. How?

I have bricked Kindle fire while trying to install Android Market. To the point that shell doesn't work.
I made myself a factory cable. So I can easily go into fastboot mode. I tried various ways that people post in different threads. None seem to work as expected.
Is there a way to completely flash the original amazon ROM in fastboot?

Update: fastboot gives me < waiting for device > now. I'm still using the same factory cable that I made myself and KF looks like it is in fastboot state - the logo shows up on the screen.
I will recheck factory cable a little later. Maybe it broke or something. Though KF still recognizes it and goes into fastboot mode.
Any ideas?

There seems to be very little help on how to use a factory cable. I am in a similar boat as you. Shell works for me but adb commands do not. I can't push or pull or install. I can navigate, change file names, and move files to some directories. My problem is that I don't know how to put the stock rom on and flash it. I actually have 6.2 on the sdcard but don't know what to do with it.
As for your problem, I experienced the same thing. adb devices didn't list my KF but I could see it in lsusb. I typed the usb description at $ "1949:0006 Lab126" and it called me an idiot or something but then I typed ./adb shell and vioala. I'm sure that didn't do anything and won't ever work again but there you have it.
I have a couple of open questions out there to see if we can get help and if I learn anything I will make sure you hear it next.

You must insert cable, when switch off kindle by pressing button about 20sec and press once again, kindle will be in fastboot.
After kindle will be in fastboot, with Kindle Fire Utility v.6 install TWRP recovery and with recovey install stock or CM7 firmaware.

Admittedly, I am a little green when it comes to this but I never got it to list in fastboot devices either with a cable (and I am not sure I am supposed to), you can check if its connected in fastboot mode by:
fastboot -i 0x1949 getvar product
it should return "kindle"
from there I did:
fastboot -i 0x1949 boot twrp-blaze-2.0.0RC0.img
fastboot oem idme bootmode 4000
fastboot reboot
To get twrp up and running then I flashed the prerooted 6.2.1. Going back to the orginal rom should be similar

Ok. Passing "-i 0x1949" to fastboot helped and now I can communicate with KF in fastboot.
But a new problem has surfaced. I'm trying to install TWRP:
Code:
fastboot -i 0x1949 boot twrp-blaze-2.0.0RC0.img
It writes "downloading 'boot.img'" and gets stuck there. I waited for 15 minutes.
Ideas?

You need to now check to make sure your drivers are now up to date.

So it seems that I can't really do any operations with fastboot. Every command just freezes at the first thing it does. Weird.
I'm on a mac. I never installed any drivers for KF - it just worked. Do I even need a driver for KF on a mac?

There must have been something with the factory cable. I finally managed to load TWRP.
Now I'm trying to install stock ROM renamed to update.zip. I push it into /sdcard. Then in TWRP I tap on Install and select update.zip.
I get:
E:failed to mount /sdcard (Invalid argument)
E:Can't mount /sdcard/update.zip
What does that mean?

Ok guys. I found the solution. "E:failed to mount /sdcard (Invalid argument)" tells you that your sdcard is not formatted correctly. Here is the fix I did.

I already have TWRP installed and also have a factory cable. But I still have a few questions.
1. With a factory cable, is there any way to directly flash the stock firmware or do you always have to install and use TWRP?
2. From reading about TWRP, it seems that after installing it, you can then load the stock firmware onto the sdcard directory and then complete the restore operation. As a safeguard, and to make things easier, I have already put a copy of 'update.zip' on there just in case I need it. My question is - on an unrooted Fire, would it not be a good idea to stick 'update.zip' on the sdcard before rooting? That way if something goes wrong, all you need to do is get TWRP on there and the restore file is already in place. Or am I being overly cautious?

ADB shell not reconizing it.

I rooted it and installed CM7 on it, CM7 was getting a boot loop so I did a factory reset, I read online that I should reinstall CM7 to help get rid o the boot loop, i turned off the kindle, putting it into recovery mod (like a t**t). Stuck in FFF boot loop, windows reconizses its an ADB device but nether the KF utility, nor ADB thinks its plugged in. I can mount it as a mass storage device. Any help is appreciated.

As i was trying to explain adb shell keeps telling me the device isn't found
And before you ask, yes i have installed the drivers and yes i have reinstalled them and yes i have rebooted the device and my computer

Did you try using the command prompt instead of the KFU? I had success doing it manually.

yup, no luck

Remove the KF, uninstall the drivers, restart Windows, and install them manually.
That should work.

no luck, still stuck

Did you edit the "adb_usb" and "android_winusb" files?

HOLY **** after ~ 4 hours of tinkering i got it!!!
Within the KFU i installed the TWRP recovery and while it said waiting for device, I restarted it. I had done this before but it didn't take.
I LOVE THE KFU, IF I HAD ANY MONEY I WOULD GIVE IT TO THEM.
If anyone in the future has this problem and has any questions, PM me and I will try to help you as best as I can.

Unbricking Kindle stuck at Boot Logo/Recovery loop

Before you get all mad at me, I know there is another thread for this. This is a method that has worked for me when all other methods have failed.
I found out about this after looking around the interwebs for a while when my Kindle was stuck in a recovery loop, or stuck at the boot logo.
Your Kindle is stuck at the boot logo? I think I can help! Follow these steps!
This is WINDOWS ONLY for the time being!
1. Download and extract Kindle Fire Utility. You should be able to easily find it on the xda forums.
2. Reboot your PC.
2.5. If you have FIREFIREFIRE, go into the drivers folder in the Kindle Fire Utility and open up adb_usb.ini. Add the following line:
Code:
0x18d1
Do not delete the other lines.
3. After the reboot, connect your Kindle via USB. Go into where you unzipped Kindle Fire Utility, and run install_drivers.bat
4. Once that's done, open up a command prompt and navigate to the "tools" folder of the Kindle Fire Utility.
You do this by using this command:
Code:
cd (File path to tools folder)
Or in my case:
Code:
cd C:\Users\ZombiePiratez\Desktop\KFire Utility\Kindle Fire Utility\tools
5. After that, run the following commands:
If you DO NOT have FIREFIREFIRE, then use these commands:
Code:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
If you DO have FIREFIREFIRE
Code:
fastboot -i 0x18d1 oem idme bootmode 4000
fastboot -i 0x18d1 reboot
If all else fails, try these commands:
Code:
fastboot oem idme bootmode 4000
fastboot reboot
6. Hopefully by this point, your Kindle will be rebooting. THIS WILL NOT WORK FOR EVERYONE. Only people stuck at the bootlogo, or in a recovery loop.
Now, go have fun with your newly awesome and unbricked Kindle Fire!

Unfortunately this will only work if your windows based computer even recognizes the kindle, which mine doesn't. Thanks tho. I've given mine to my tech geek who has access to linux based system, so hopefully he will be able to recover my brick.

My Windows PC wouldn't recognize my KF stuck in recovery mode, either. I think it reported in as an "unknown USB device" or something. I had to shut down the Kindle and then plug the USB in, which for whatever reason got my computer to recognize it. I think it might be similar to the effect of a battery drain?

Did it just immediately recognize it, or did you have to re-install drivers? And i'm not sure about the battery drain thing...

I guess I should make note that by this point I'd uninstalled the driver I used. It was recognized as "kindle" once after I plugged it in while off, so then I went ahead and manually reinstalled the driver (from Jayce Ooi's site), which allowed the fastboot commands to work. Otherwise, the command would hang at <waiting for device>.

Thanks! My kindle fire was stuck at the firefirefire logo. My computer couldn't even recognize my kindle but I uninstalled the Android ADB composite interface and plugged it back in, when the kindle was off. Then I used your commands to get fastboot. I installed TWRP, now I'm stuck in TWRP and can't mount my sd... to flash any rom.

Thanks
Thanks for the info. i thought i'd bricked it and the info worked a treat. that will teach me to keep my mouth shut "of course i can root your kindle"

try fixing permissions under advanced, and then make sure only the sdcard box is marked in mount option.

I'm sorry but I tried all the steps above but KF's still stuck at boot logo. I flashed CM9 stock kernel 3.0 with FFF 1.4a and CWR, wiped everything and factory reset, then install...but it just hangs at the blue skating droid logo... any idea?

The Unbrick utility won't help in your case. When the device hangs at the boot animation or goes to a blank screen afterwards, the problem is usually one of three things.
* the rom installed is corrupted
* you didn't wipe the necessary data before installing
* you tried flashing a rom that's incompatible with the recovery you are using (I'm betting this is most likely the case)
Try installing a different rom (preferably non-ICS) to see if that fixes the problem. Of so, check to see if you're using the latest version of CWM by Hashcode or install TWRP to run ICS based roms.
Any further questions regarding this matter should be redirected to the Q&A section.
[Edit:] For some reason I thought this was the thread for the Unbrick Utility. Regardless, the solution is still the same.

You are a GENIOUS!!!
Thanks a LOT!!!!!!!!!!

[Q] Yet another bricked KF

Hello all,
I've got a bricked droid, and haven't been able to find a fix that worked in other threads here.
I rooted my droid successfully, and installed GO Launcher EX, along with the android market, and a number of apps from there.
Among those, busybox, metamorph (which i then used to change the wallpaper), titanium backup, etc. I had successfully rebooted after all these installations and after changing the wallpaper.
I was getting on a plane the other day and turned off the KF, and havent been able to get it to boot since.
Originally it was in a boot loop, getting to the kindle fire icon and rebooting every 3 seconds.
I tried using the KFU, but it was unsuccessful at changing the boot mode (drivers were successfully installed).
Failing at that, i tried following the instructions in http://forum.xda-developers.com/showthread.php?t=1414832
After the reboot, it is now just stuck in the kindle fire screen, and i cant run any adb commands, device not found.
Am I straight up screwed now? or anything I might be able to do at this point.
Much appreciated, thanks for any advice.

Do you have fastboot access? Try running the following...
fastboot -i 0x1949 oem idme bootmode 4000

Try this: http://forum.xda-developers.com/showthread.php?t=1422832

Thanks guys, ill try those and post back w the results.

so i tried fastboot -i 0x1949 oem idme bootmode 4000
and it seems to have been successful, in that it is now back to its original boot loop state. however, it is still not booting fully.
it seems that adb commands are now working, i can do adb shell, and navigate root folders (system etc).
zombie, i havent had much luck with that route, i had tried that earlier.

I've seen people mentioning that the cause for their brick had something to do with permissions, so i did ls -l in the adb shell, here are the permissions for some of the relevant folders. if there are any others that might be helpful, let me know.
root -> drwx------
system -> drwxr-xr-x
sdcard -> lrwxrwxrwx
oh and framework-res.apk -> -rw-r--r-- (same as all other files in that directory)
i did modify the framework-res to change the background image. it successfully booted at least once after the modification - i used metamorph, i loaded the file, then rebooted for it to take effect. this was successful, but i believe it was the next reboot which did my kindle in, so possibly related.
i rambled a bit, but maybe if i replaced the current framework-res.apk with the stock framework-res.apk, that might be worth trying? are all stock framework-res.apk files the same at stock? because i don't have a copy of the original that came with my kindle.

i would go back into fastboot and then flash over TWRP... and then reinstall your os from scratch. it would probably be easier than trying to root around fixing it from the inside.

Thanks xrishox, I might do that. Is there a thread detailing how to do that?
When I tried doing fastboot I lost the ability to use adb commands so I'm not sure how to go about flashing twrp.

Download the fbmode binary and TWRP image. Then run the following.
Code:
adb push fbmode /data/local/temp
adb shell /data/local/tmp/fbmode
arbiter reboot
Your device should reboot and be stuck on the Kindle bootscreen. You are currently in fastboot mode. Now run the following...
Code:
fastboot -i 0x1949 poem idme bootmode 4000
fastboot -i 0x1949 boot twrp-blaze-2.0.0RC0.image
Your device will reboot after that last command. It will boot into the TWRP installer. When it completes, tap "Reboot". Then boot into TWRP recovery and install the factory update, or a custom image that won't replace FireFireFire and TWRP.

Howdy!
I recently just dealt with this same issue. My KF was stuck in boot loop and wouldn't be recognized by my computer. I left it in bootloop until it ran out of battery. Once it was completely drained, I connected it to my computer and my computer recognized it, I then reinstalled the drivers. Right after that I used KFU to change bootmode to normal boot and let it fully charge! Good to go! Hope this helps someone.

from the op of kfu:
Known Tricks
•If you end up stuck at the yellow triangle, in KF Utility select Boot Normal, wait for it to say <waiting for device> and then press and hold the power button 20 seconds until the fire turns off, then when its off turn it back on. This sometimes happens, I have yet to find a clean solution
•If you end up stuck with a yellow triangle, do not EVER unplug it. Leave it plugged in. Check the windows drivers to make sure it isnt showing as "kindle" again. Fastboot is different and can cause this.

[SOLVED] BIG PROBLEM with TWRP please help!

I have previously installed TWRP which has run without any problem, helping me to install the rooted version of KF 6.2.1 firmware posted here in xda a month or so earlier. It has been running fine until yesterday.
For some reason, when I ran Market, it asked for secure login with a "Retry" button which did not work. When I checked it was still registered with my GMail account for Google. Then the wifi started to go on and off for no reason.
I realized something went wrong so I decided to re-install the rooted 6.2.1 using TWRP.
The installation process completed successfully. I pressed "Reboot" button then choose "Power off". However when I restarted the KF by pressing the on/off button, it booted into TWRP by itself (meaning when the yellow triangle came up, I DID NOT press and hold the on/off button to boot into TWRP; the light went orange by itself and booted into TWRP). I switched on and off several times, but it booted into TWRP by itself all the times.
I decided to wipe everything before re-installing the firmware. I got back into TWRP and wiped cache, Dalvik, System, Factory reset and SDcard. When I press "Install" button, the copy of firmware is no longer on the KF because of complete wiping. I press "Mount" -> "Mount USB storage" and hook up the KF to my PC, so that I can transfer the copy of the firmware to the KF.
I repeated the process (firmware installation was again successful), but I still got the automatic booting into TWRP instead of normal boot.
Then I tried using KF Utility 0.9.2 to update TWRP (I originally installed TWRP using the TWRP Installer). However, I could not get it into fastboot mode (the Utility says "fastboot mode: no"). The instruction from the Utility said if installation did not work, try reinstalling the drivers - I ran "install-drivers.bat" and reinstalled the drivers, but did not get into fastboot mode to do anything.
Then I tried to install CM7 instead of the original firmware. I copied CM7 onto KF and used TWRP to install the zip. Again I wiped everything before installation. Unfortunately this time, the installation process did not complete. I rebooted the KF and again it auto-boot into TWRP (probably because there is no OS on the KF now).
I can still boot into TWRP without problem. The nightmare now is that:
When I try to mount USB device so as to connect to the PC to transfer files, my PC does not detect it as a drive.
Before the screw-up, it shows in Windows Explorer as "Kindle" (or "Amazon Kindle device"). Now when I go to device manager and click "Disk Drives", only the HD of the PC shows.
The "Android Phone" ("Android ADB interface") still shows in Device manager when I hook up the KF, therefore I guess I can still use ADB.
So these are my two questions:
(1) How do I get out of the "reboot loop" and stop the automatic reboot into TWRP so that I can boot normally into Android (this is presuming I install the firmware successfully)
(2) What can I do now that "USB Mount" in TWRP does not work? Can I fix it or can I reinstall TWRP?
Thanks.
Desperately yours

If in Device Manager it shows up as "Android Phone" that means you have the ADB drivers installed and it will not mount as a drive. Simply delete the device from Device Manager and replug the kindle to your computer, or just use a different computer.

ALL PROBLEMS SOLVED
Thanks. I uninstalled ADB then reconnect KF, and it reinstalled ADB. When I press "Mount USB storage", my PC detects KF as a drive ("Kindle") again.
Actually I also solved the problem of TWRP bootloop:
http://forum.xda-developers.com/showthread.php?t=1390773
I used ADB to issue "idme bootmode 4000". This took my KF out of the TWRP bootloop back to normal boot. I am surprised to see that CM7 installation is successful, despite it seemed that in TWRP this was cut off in the middle, without the usual "installation successful" message that came after original firmware installation.

Can you see it in adb by doing an "adb devices"?

just for the future - the commands to set bootmode to normal depending on the current bootmode and version of fff:
with adb:
adb shell su -c "idme bootmode 4000"
adb reboot
with fastboot:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
or
fastboot -i 0x18d1 oem idme bootmode 4000
fastboot -i 0x18d1 reboot
or
fastboot oem idme bootmode 4000
fastboot reboot
