Hi guys, had everything working swimmingly after getting a replacement HDX from Amazon (due to screen flicker) and the replacement came with Rootable software! yay!
Anyway, even though I was running on Rom Slot 1 and not the Stock Rom, when I used the Wipe function it wiped everything - stock and slot... I hadn't created a recovery of Stock Rom (yes, I didn't RTFM... but I imagined I could ADB push the amazon update file and go from there... ADB was too intermittent to do this and when the HDX booted again I stupidly accepted the Kindle Fire System Recovery and tried to "recover" when there was nothing there...
So now I have the silver Kindle Fire logo... I do get MTP USB Device showing up on my PC (but can't get ADB to connect etc) and can also boot into Kindle Fire System Recovery (but the device doesn't then get detected on the PC)...
Any thoughts???
Any update on this? I am wondering if you got it working or not.
i did the same thing :crying::crying:

No it won't wipe the stock slot. What you did was wiped the working rom slot & then rebooted into it, where no OS is, because, well, because you had just wiped it. Try Unbuntu for adb access. You *MAY be able to set it to boot to stock, or push the system files to it via adb, but I am not in a position to recreate this issue.

Hello
I got my HDX rolled back today, rooted it using Towelroot, all worked fine
Installed FLASHR and there was an image I had for TWRP, I tried mounting it as recovery but failed, then there was a Kernel option which I did install it with (The same TWRP Image), when the device rebooted it was stuck in Grey Kindle Fire screen,
I read around for methods and found some, the problem is that my device is not seen by ADB and when connected to USB there is no response.
Can this device be unbricked? Do I need the fastboot cable?
I also have taken a backup using FLASHR and it stayed on the device, is this useful?
Thanks for your time
TWRP is not compatible with 3.2.8. Try powering up by holding the on/off and volume-up buttons together. It's possible Amazon's (crippled) recovery is still intact. From there you may be able to reset your device. If successful read through the forums to determine what is possible. Options with 3.2.8 are limited.

Thanks for your reply, I did try power + volume up still got the grey Kindle Fire logo, I did read a lot in this forum but didn't succeed in finding a good solution
I got the factory Cable
The device was recognised as USB, a black screen was showing.
I tried ADB it said device not found
also fastboot -i 0x1949 etc keeps waiting for a device
any hint? is the device dead?

No, this device is bricked for good assuming that your device was on FW xx.3.2.8:
- you writed incompatible twrp image on recovery and also on boot partition, the second flash was deadly
The only option for custom rom for FW xx.3.2.8 is to use safestrap and nexus for safestrap 1.0.1.
Hello fellows!
I'm afraid, I bricked my kindle.
I wanted to check out the permissions for /app using ES-File Explorer. My screen went instantly black and stuck. I didn't change anything, I just clicked on "details". I killed the device (holding down power button) and afterwards it doesn't boot. The kindle logo stays gray and it reboots 1 time. This reboot ends in the Fire System Recovery, where I can reboot the device or do a factory reset.
Factory reset didn't help.
I have one problem fixing the device:
- The device is only recognized as MTP-Device while it tries to boot the first time. And this is not very long. It isn't named Kindle, but Android in "Devices and Printers". Unfortunately I can't uninstall or "update" the driver, while the kindle tries to boot.
---> ADB tells me: "error: device '(null)' not found" .
Do you have any idea how to save my kindle?
What I wanted to do before killing the device:
- Get the kindle to show Wallpapers (Totally worth to brick the device! -.-)
EDIT: I tried a second Factory Reset. Now it is fully stuck at the grey boot logo. But my system detects the kindle now correctly.
Next problem: adb shell command end in: "- exec '/system/bin/sh' failed: Permission denied (13) -"
EDIT EDIT: Getting the kindle into real bootloop is not always possible. It happened once and now I'm stuck in the System Recovery again and can't connect to the device :/
You might have to reroot the tablet. I think you can do it with ADB, or HDX toolkit might work. Or maybe you don't have to root at all, I recommend to reinstall ADB.

You didn't indicate if your device was rooted (assume yes), Safestrap installed, FireOS version, etc. But in the end it really doesn't matter. With a locked bootloader there is nothing you can do to recover from this type of failure. Even if the device is detected you will not have adb access. Nor will fastboot commands work (most are disabled). Native factory reset only clears the data partition; it does NOT fix errors in the system partition. If still under warranty contact Amazon about a replacement.

It was/is rooted.
So even a Fastboot cable won't work?

Fastboot cables are useless on a HDX as 1) device interface does not support alternative pinout; and 2) fastboot environment is crippled.

Oh man! **** Amazons Bootloader!
I called them and they told me, that there are no Tablets to replace mine. They'd give me a kindle 8.9 for 303€ and that's all.
Thank you for answering. I'm going to throw my kindle away

Well, I wouldn't toss it just yet. Stick it on a shelf and move on. Possible (albeit unlikely) a future unbrick method or bootloader exploit will become available.

Device: Nexus 9 (Wi-Fi), Bootloader Unlocked
Computer: Windows 10 (Bootcamp on a Retina MacBook Pro)
After and unsuccessful attempt to install CM 12.1 on my Nexus 9 (Wi-Fi) using TWRP, I tried using this method to return to stock:
http://forum.xda-developers.com/nexus-9/general/guide-nexus-9-to-stock-guide-unbrick-t2975668/
I thought it had worked perfectly, but the tablet still would not boot. I went back and looked at the command prompt log and realized I had made a grave error: I had flashed everything except for the system image. I re-entered fastboot in an attempt to fix it by flashing the system, but now the tablet will not connect to my computer at all. I have tried to remove and reinstall the ADB drivers, but it doesn't show up at all in Device Manager. I tried booting into recovery via fastboot, but got an image of the android mascot knocked-out with an exclamation point, presumably since I over-wrote it with the method above.
Any ideas on how to restore the fastboot/adb connection with my computer? If I can accomplish that I can presumably just flash the system image and that would restore the stock ROM.
Any insight at all would be much appreciated.

Hello,
I have reported this thread to be moved to right Q&A section in order to get expertise help.
-Vatsal
Have you ever tried to connect your tablet to another computer?
Turns out I forgot to actually press the button in fastboot that enables the USB connection (I feel even more stupid now). Was able to return to stock, albeit with the "This device is corrupt" message during boot.

I got the same message yesterday after I returned to stock kernel from a custom one. What I did to get rid of that warning message was to flash all img file(boot, cache, recovery, system, vendor) in MMB29K factory image. (Bootloader is optional) [After that I also performed a factory reset but this step might be unnecessary, do it if the message still exist after flashing stock images] If you don't like that warning you can try these procedures.
I think my 4th Gen Kindle Fire is bricked hard. I had rooted a while back and was running fine till one day it stayed stuck on the Fire logo during boot. I can get into recovery but when I try to sideload stock rom with adb I either get a message that says "Rom not compatible" or it transfers 0kb and nothing happens. I tried factory data reset but that doesn't work. I even tried the methods from here - http://forum.xda-developers.com/fire-hd/development/video-linux-iso-unbrick-fire-hd6-hd7-t3474999 using the Archlinux boot CD with AFT2 Tools, but when I issue the ./reader.sh command, it just hangs.
Are there any options for me?

Also wanted to mention that I get Failed to mount /cache in the recovery screen. Is there anyway to fix this?
I have the exact same issue. Any help?
You ever got that issue fixed. I'm facing the same problem
I had such problems, when i had flashed twrp to cm recovery.
The only way to fix this in my case was to use fastboot flash.
And i managed to copy the rom through adb commands (if i remember right)
My HDX 7 64GB is stuck in a boot loop after 4.5.5.3 update (I did not believe amazon would offer another update so i did not block OTA updates). It was fully Stock except for King root.
Now after the first boot loop it boots always the Fire System Recovery.
Is there any possibility to fix this?

Not likely short of placing the device in 'bulk' mode and taking a series of rather technical steps to erase and then rebuild your device. Entering bulk mode may be tricky if it is unstable during boot.
How would I place my HDX 7 into 'bulk' mode?

Ok. I tried to get my HDX 7 into bulk mode, by using a fastboot cable. But it only enters 9008 QDL mode, how do I get from there to the buk mode?
As I tired different things. My HDX 7 is now stuck with the grey kindle fire screen, but I can see the device in adb. The problem is that I can not execute any command, because it is shown as unauthorized. Is there a way to still boot fastboot?

A fastboot (aka 'factory') cable is ineffective on this device. Being stuck at the bootloader logo with no connectivity is generally fatal. Details matter; how did the device and up in this state?
@draxie - thoughts?
I wanted to unlock the bootloader and rooted it via Kingroot, but had no time that day to get further. Some days later I discovered the HDX 7 was booted to the stock recovery.
I tried to reboot it, but it always tries to boot the rom and start over and boots the stock recovery.
Then I called amazon, and they told me that my HDX tried to update to 4.5.5.3 and that they can not help me.
Then I tried the factory reset, but it did not help either.
Through experimentation I noticed that if the tablet booted while connected to my linux notebook, it would sometimes stop at the grey kindle fire logo and offer a adb connection, that I sadly could not use because i don't have the necessary ADB_VENDOR_KEYS.

I am not aware of any method to reliably force a device into 'bulk' mode via button pushes, etc. The member referenced in a previous post has the most experience in this area; see if he responds.
FWIW - accepting a FireOS 4.x OTA update on a rooted HDX device is almost always fatal.
Hopeless...

Condolences, perhaps...
If the bootloader is unlocked, Power+VolDn won't enter fastboot
(although that doesn't hurt trying), and I don't know of any exploits
that would get adb executing commands on an unauthorized device.
(Of course, trying "adb reboot bootloader" won't do any harm, either.)
If adb used to work before, there _could_ be an absolutely minuscule
chance that whatever host was used still has adb keys in the .android
folder of the relevant user account's home directory, but given that factory
reset was performed, the corresponding public key(s) on the device are
probably gone... Still, if there are keys in .android (and, especially, if there
are different versions on different hosts and/or under different user accounts),
then testing them all may be worth a try. Just in case...
The steps involved are
Stop the current instance
Code:
adb kill-server
Copy the keys to try to .android
(on the test host in the test user's home directory)
See if "adb" manages to connect:
Code:
adb shell
(This needs to be run as the "test" user.)
And, the above steps should be repeated for each set of keys....
I would NOT hold my breath, but one might get lucky.
