I had bricked my 3rd gen HDX but was able to get a new Motherboard/Daughterboard combo off Ebay. Got them successfully installed. When i boot it shows a grey kindle fire logo for a few seconds then shows a white screen with diagnostics on it. Cant do anything but hold the power button to reboot. I do have ADB and can reboot into recovery. My windows machine sees the kindle as an MTP usb device. I dont want to proceed without proper guidance. I just want to get it working and stop messing with it. Any help is greatly appreciated! Thanks!

I was having trouble with ADB on my newly acquired ViewSonic ViewPad E100. I thought rooting it and/or installing a new OS/ROM might help.
I saw this thread:
http://forum.xda-developers.com/showthread.php?t=2021203
Where someone pointed a guy to a universal root tool:
http://forum.xda-developers.com/showthread.php?t=1886460
I got the tool to run, and tried to use the #1 - New Standard Root - it got as far as to reboot the device.
Maybe I wasn't in trouble yet. But I waited for a bit and the device was still on the "ViewSonic" boot animation. I stupidly pulled the usb plug out to check out the device closer. It didn't boot. Then I restarted. I can no longer get farther than the "View Sonic" boot animation.
Okay, I know there's some special boot methods in Android, so I try a bunch of key combinations. Power+volume down doesn't seem to do anything [yet] but when I press Power+volume up, I get the android guy with a red exclamation in his belly:

It's possible I see a flash of a better image, like this one:
http://www.android-hilfe.de/attachm...ery-rotes-warndreieck-2012-09-22-03.41.16.jpg
So no idea what to do. I figured it couldn't get much worse, so put a recovery "update.img" for a gtab on an SD card and then tried to reboot, with holding vol+power, just power, no luck with any combination.
Then I discovered 'nvflash'
http://raywaldo.com/2011/01/nvflash-for-dummies/
I think I'm following the steps right (for a gtab at least), but I can't get into APX mode. I can get *something* when I hold vol-down+power, I actually get my computer (Windows) to show me some internal storage of the device I guess... There's no way for me to install APX drivers, and I don't see the screen "flash" either, just sometimes I get USB storage attached.
Can I recover from this? Are there any more things I should be trying? Does anyone else out there have this device? Where else can I look for help? I just got this device this week and was hoping to use it for development!
Thanks in advance.
Hi everyone. I have a strange problem with my Kindle Fire HDX 8.9. It downloaded the software upgrade, but it won't upgrade. Yesterday the device shut down and rebooted in fastboot, than it was completly died. I can't boot it. If I connect with USB cable I get: QHUSB_BULK. The kindle wasn't rooted. The display is black, there isn't Kindle Logo.
Sorry for my bad english

Press and hold power button for 20+ seconds to see if you get a response. Make sure you have a full charge (any response to the charge cable?). Could be a hardware problem but more likely a botched upgrade. If the device is still under warranty reach out to Amazon. They are pretty good about replacing faulty devices.
I'm in the same boat as the OP.
I have a botched upgrade and Safestrap seemed to got formatted.
Stuck in BULK mode using a Fastboot cable with no ADB access. I can also get to the grey logo screen that prompts for a Factory Reset or Reboot but nothing happens there either.
Am I SOL?
Well I have the same problem in my HDX 7.
I downgraded from 4.5.3 to 3.2.4 because I wanted to root the device.
The installation was successful and my kindle rebooted just fine....I started to download some apps from store....I left the device for 10 minutes closed not turned off and when I came back to open it not to turn on the screen was black and none of the buttons where responding...I tried every combination of buttons but didn't work...My pc recognize it as QHSUSB_BULK...I found the correct drivers and now I can connect it to PC but only in QHSUSB_BULK mode...
It's not rooted,
doesn't have safestrap installed
it doesn't reboot in stock recovery and
It doesn't have warranty cause is outdated
Thanks in advance

Sounds like you bricked it.
If you can get it to show up on your computer (e.g. see Device Manager), you will likely be able to just follow this guide: http://forum.xda-developers.com/kin...-to-unbrick-kindle-fire-hdx-firmware-t3277197

Thank you for the context. Detailed response follows:
So i've had a Kinde Fire HDX for quite some time and recently, annoyed by the Fire OS, i attempted to install TWRP to install Cyanogenmod. However, after receiving errors such as 'FAIL:Locked hw' or something of the sort, i left it and wanted to boot back into the normal OS. When i did this, it left me in a bootloop. To try and fix this i tried to hold the power button and vol up button to reach file system recovery and reset to factory settings. After i did this, it sent me back into a bootloop and was not recognised by my computer. Help please?!

Answered here (posts 284-292).
I was attempting to replace my custom rom, which was Lineage OS, with the kindle fire stock OS. I was using TWRP for this. I flashed the zip file to my kindle. I then wiped everything and rebooted. This is when I was greeted with a black screen.
I think this is where I messed up. I should have flashed two zip files, but I only did one (there's a 4.5.5.5 software update and a 3.2.5 software update. I only did the 3.2.5).
The kindle still connects to my desktop, but it shows up as an unknown device, so Windows won't let me update the driver and use adb or fastboot commands (or at least I haven't figured out a way that I can). Pressing and holding the power button or any combination of buttons doesn't display anything or disconnect the kindle from my desktop, so I dont think I can turn it off or reboot it either.
I'm not sure if I would even be able to fix this, based on what I've just said. Any help would be appreciated.

You soft bricked your device with an invalid bootloader downgrade. Recovery is possible but quite challenging. Best option is to try the 1-click bootloader unlock tool. Good luck.
