Gen2 Kindle stock restore - stuck in a boot loop - following overlode's doc

Overlode - Huge thank you for the simple list for us NOOBS of how to get a stock Kindle stuck in a boot loop back up and running. I am having some problems though and was hoping for some help.

I am running Win7 on my PC. I've installed Android SDK, I have a factory cable and my gen 2 Kindle has the pretty "Fastboot" logo with the flashing green light and a non-flashing red light. When I go into my devices manager and see the "Otter2-***.***" it does have the yellow triangle. This is where I deviate from your instructions (in your .doc file). When I right click I do not see the simple "update driver software". I have to go through several windows to finally reach that option. No big deal. But... I clicked the option to "browse my computer for driver software" then "Let me pick from a list of device drivers on my computer". I do not have the option to select "Kindle". I went to have it list ALL DRIVERS and it is not in that list either.

I'm stuck. I don't know how to get the drivers up and working so I can continue with your instruction sheet. I REALLY appreciate all your efforts (with the drop box and everything). I've been fighting this boot loop for a month now and I'm scared to make a bigger mistake. I can build a pc from scratch- no problem... programming and mobile devices just make my brain hurt. Be kind. Everyone seems to throw around abbreviations like Halloween candy and this just makes me want to run for the hills. I'm learning but please don't just assume I know what you're talking about. Thanks in Advance!!

EDIT: (a day or so later) Hey.. Nevermind. I was able to finally figure things out and downloaded KindleFireFirstAid and was able to wipe it out back to stock using my factory cable. The boot loop was limiting my options. Thanks Anyway.

Fastboot

What would be stopping Fastboot from recognizing my device? I have a fastboot cable for my kindle fire 2, I plug it into my computer then into the kf2, the kf2 boots up into fastboot mode my computer see the kindle and it has the proper drivers installed, but fastboot can't see it for some reason.
I had this problem before when I installed CM10 onto my kf2 but that was a year ago and for the life of me I don't remember how I got fastboot to see my kf2.
All i want to do is downgrade my kf2 back to stock and sell it on ebay. PLEASE HELP! I'm dying here

Any other options?

Overlode-My wife;s KF2 was stuck in boot loop so I tried your stock restore method with a factory cable. Everything seemed to work fine. The drivers were installed, fastboot commands worked on the device, etc. When I did the last reboot step, the device never turned back on. Now the device will not power up with the factory cable or USB cable. Is there anything I can do to fix this KF2 or is it permanently screwed? Thanks.

Kindle Fire 2 - Bricked

Today I tried the procedure in post http://forum.xda-developers.com/kindle-fire-hd/fire-2-development/kindle-fire-2-7-stock-restore-t2840987 but as I use Linux and have the SDK installed I entered the commands from console.

A couple of days ago I flashed Cyanogenmod using very similar steps.

Here is my log for the attempt to restore the stock ROM:

What is worse, after the failure I rebooted in order to restart with the procedure that worked a couple of days ago and leave Cyanogenmod in the Kindle...
but...
No reboot, no lights, no USB detected....
It seems that the tablet is hard bricked.

Is there anything that can be done except using it as a paperweight?
Thanks in advance

KF2 - hardbricked and restored.......almost!!!

Hi,

I have a KF2, which I had previously rooted and installed CM10 custom ROM. Had no problems with it, but decided to try a few more custom ROMS. Forgot about NOT using the KFU program as it was for KF1 devices, and for some stupid reason went ahead and flashed the wrong bootloader.

Result is fairly predictable - HARD BRICKED KF2!!

Thought that was it - searched the forums and everyone was saying the same - no way back from that! Then I came across Kurohyou's post and brilliant guide about hacking a card reader and attaching direct to motherboard. Followed his guide and voila - managed to boot up into recovery (TWRP). However after pushing the ROM files etc to try and install CM ROM again just kept getting "error flashing ROM" . I left the thing after trying various methods and different PC's etc to push the files across and gave up. When I went back to it this morning I couldn't get it to boot into recovery - which I thought was a bit strange. However FASTBOOT mode is ok - I have made a fastboot cable myself which works fine. Kindle was booting up with orange logo, quick flash, orange kindle logo again and repeat. It would not boot into recovery even though I had flashed the correct files via fastboot.

Again almost giving up when I came across Overlode's instructions. Followed them to the letter, and what I am left with now is the standard Kindle Fire logo (orange) which blinks after about 5 seconds and just stays there - left it for about an hour just in case....
I can post screenshots of me flashing the files as per Overlode's instructions if it helps. I get a few errors when using the wipe command, response is "erase successful, but not automatically formatting. File system type not supported" everything else is ok.
I still have the hacked card reader attached which through Ubuntu can see the EMMC directly so don't know if might be worth copying the files directly instead of flashing via fastboot?
Any suggestions gratefully received...... I'm at my wits end with this thing - I know I should have left well alone!!! but I feel like I have run a marathon with this thing only to have fallen flat on my face 5 metres from the finish line!!

Thanks in advance for any help.

Hi - see my last post - I too have a hard bricked kindle. if you're handy with a soldering iron you can try it - I can confirm it does work.
details here -
http://forum.xda-developers.com/showthread.php?t=2415870
I managed to get my kindle from nothing (not even charging light) to back up and running with TWRP installed. I couldn't get a custom ROM installed, kept getting errors - but I think my board has other issues. While I was putting it back together I managed to stick my screwdriver through the battery (don't ask!!!) Since then I think I have caused other damage and it was never the same again I think I may have damaged the memory or the EMMC..... on the hunt for new motherboard at present!
Good luck!
