kindle fire in boot loop. Howto for restoring with fastboot? - Kindle Fire 2 Q&A, Help and Troubleshooting

I wanted to get 4.2.2 on my fire2, so I went throught the tutorials to root and install twrp recovery which worked great. I downloaded the CM10.1 sgt7 and gapps for the fire 2 in the dev section and proceeded to reboot into recovery. I wiped the system and flashed the rom and gaps, wiped cache/dalvik and hit reboot.
dreaded kindle fire boot loop. The only thing I can think is that the rom DL was corrupted. It really didn't take long to complete the flash in twrp, probably less than 10 seconds. I really should have checked the md5.
OK, so I get a fastboot cable online and it shows up today. I can't seem to locate a tutorial of how to restore with fastboot though... can someone point me to a link?
Thanks,

Can you get into recovery?

Always factory reset when flashing a ROM that is completely different from the one already installed, or you will run into a bootloop.

I was able to get it back. Been running 422 for a few months. I had a bad Roman do from what I can tell. I was not able to get to recovery without restoring with a fastboot cable.

[Q] KF won't boot and is not recognized by KFU or adb

I just got a Kindle today and decided to root it. Here are my exact steps.
Downloaded latest KFU
Ran it, ran input 2 for permanent root
installed TWRP and FireFireFire
made a backup of my current rooted stock ROM
wiped everything
flashed CM9 reloaded ICS ROM
didn't like the ROM, so I went back into recovery
wiped everything
flashed AOKP ROM
reboot
and nothing.. the screen went black
I click the power button and the green light will come on and then everything goes black again
I reinstalled the drivers and got it to boot in recovery. I wiped cache, dalvik, and factory reset. I tried to boot but it won't boot into anything, it just turns off.
I'll try to restore my nandroid and see what that does
Edit: It rebooted into my nandroid of the stock ROM. Was it just a bad AOKP download? Should I run the perm root =, TWRP recovery instal and FireFireFire install on KFU again?

I have no idea why your AOKP install failed, but you should check the MD5 sum on those zip files before you flash any new ROM. You don't need to root stock again if you intend to flash a new ROM, but make sure you have TWRP 2.1.1 and FFF 1.4a installed on your device before you try it again. As long as you have those two piece in place, you can get back to recovery and flash something again if anything else should go wrong.
Download a new update zip and give it a try!! check md5 sum first!!
Alright I have never checked an md5sum. I never really knew it was important! I found out how yo do it and what program to use, so I will definitely do that next time! Thanks

[Q] Possible to flash update.zip from fastboot?

I have a Kindle Fire that I rooted using KFU. FireFireFire and TWRP are both installed. It was working fine for a while, but after I installed the Google Apps and set up the Market account, the Kindle froze. After I turned it off (holding power for ~20 seconds) it would not turn back on for about a half hour. When it finally did turn on, it got through the FireFireFire bootloader screen and went to the regular loading screen, then froze on a black screen (but with the backlight on). I can boot into TWRP, and I have a stock update.zip on the Kindle already, but as soon as I touch Install the recovery freezes (the screen updates to the choose a file menu, but then I cannot select anything or go back).
With all that back story out of the way, I want to try to restore the Kindle Fire to stock and see if the problem persists. Well, I don't want to per se, but it's technically my girlfriend's Kindle Fire and that's what she wants. Since it can get to FireFireFire, I assume I can still use fastboot. I have read up on how to use fastboot to flash a new recovery or do a data wipe, but I was wondering if it is possible to use fastboot to flash the update.zip or update-kindle-6.3.1_D01E_4107720.bin? And if so, what would the command be? The fastboot section of the beginner's guide only mentioned flashing the individual pieces (boot, system, etc..).
It has been asked before if you can fastboot flash a rom to your kindle I dont believe that has been determined very good question so far I have not seen an answer. Im guessing flashing stock would fall under the same category. I would say no because when you fastboot flash its to a specific destination not multiple partitions.
I would boot to TWRP, select Wipe then do Cache, Dalvik Cache, and Factory Reset.
Then if you want the pure stock, then flash this version of Stock 6.3.1(No Bootloader or Recovery).
This will leave FFF and TWRP intact so if you need to get back to them.
If you do want Google play and Super User flash this file.

Thanks for the reply, however as mentioned I cannot do anything in Recovery. If I touch Wipe the same thing happens as with install, it freezes after I complete the first menu change.
I would re-install TWRP then and go from there.

twrp wont boot

ok i have a 2nd gen kindle and managed to root and install bootloader but when i select recovery it just hangs on booting? i reflashed an older version of twrp still same thing? (solved)
Wait how did you fix it? I'm having the same problem!
I rooted it using this guide, http://forum.xda-developers.com/show....php?t=2075959, and then I used this guide, http://forum.xda-developers.com/show...light=recovery, to add twrp so I can flash CM. Everything seemed to go well except that I am unable to enter recovery mode. When booting normally it works fine and loads into the kindle OS but obviously, I want to replace that. I have tried searching the forums and trying a few different things but so far nothing has worked.

TWRP will not flash roms.

I have been going crazy for about a month trying to flash cm 10.1.3 on my kindle fire 2. First i rooted the kindle then i followed the steps here to get twrp. http://forum.xda-developers.com/showthread.php?t=2100963 Since then i was not able to flash any roms or even go back to stock. I have tried KFfirstaid, http://n2aos.com/ recovery but I just get kindle error message. I reflash twrp and back to where i am now. I have twrp 2.6.3.1. If anyone could help that would be great.

That error basically means that rom is incompatible with your device. I recommend grabbing a copy of cm11 not cm 10.1 and flashing it, it has way more bug fixes and improvements than the old cm 10.1 builds.
I tried slim rom and cm11 same issue flashing both. I was able to get back to stock think im going to wait a bit before i root and flash again.
You sure you are on a kindle fire 2 then? You can always go into fastboot and query "fastboot -i 0x1949 getvar product" and it will tell you the model's codename. Or just look for it in the build.prop on the system partition.

[Q] Stuck in TWRP recovery

Ok, so I have a question that either does not exist on Google or that I just don't know how to explain.
My Kindle Fire 2 was flashed a while back with a stock version of Android Jellybean 4.2.2, until today. I made a complete backup of everything inside TWRP and transferred all of those backup files to my laptop. I then flashed a newer version of TWRP, version 2.6.3.1. After that, i flashed the newest version of Cyanogenmod 11, Android 4.4.4.
Anyways, I got to adjusting the settings and told it to allow me to pick between rebooting into recovery or normal mode when i pressed the reboot button on the power menu.
Here is my problem though. At one point, I told Cyanogenmod to reboot me into recovery, and ever since, my Kindle will only let me boot into the TWRP recovery area, regardless of what I tell it to load in the bootloader.
How can I just get it to boot to the normal OS? I've tried reflashing the recovery and reflashing Cyanogenmod onto it. I just don't know what to do because I don't know exactly why this is happening.
I've tried wiping the /data partition too, but to no use. I still am able to wipe internal data partition, however I don't know how it will respond to that. I mean... Isn't that where TWRP is stored? I don't want to lose my recovery partition where I have no way to get back.
If it comes to it, could I replace my recovery partition with Cyanogenmod?
I am still able to use ADB and I'm able to push files. (So far)
Possible solution

I assuming you have a TWRP bootloop problem? Like everytime you reboot it, it shows you the kindel fire logo (organge/white), then to the blue/white logo, and then instead of the normal android ui, it boots into TWRP? If this is the case, have you tried selecting the 'bootmode' option during the kindle fire blue/white logo screen? That was my solution when I had the recovery bootloop problem recently.

I tried telling it to boot normal during that screen. Still goes to TWRP.
