Could Use Some Direction With A Rom and Booting

I have searched and searched for my exact issue and I am not coming up with anything. Took a stock Kindle Fire, Rooted, Recovery and BL no problem.
If I try to flash a rom that is ICS based it has issues booting. It shows fff then goes to boot and gives a black screen. If I go into fff and tell it boot normal then it will show the boot animation (say cm9 robot) and just bootloop.
I have tried to adb commands for 4000 and checked my roms are downloading correctly. I have gone back to stock with no fff or twrp then started over and I always end with this same result. I never lose fff or twrp and always keep adb other than when it's bootlooping.
If I flash a rom like CM7 or stock rooted it boots up with no issues. Is this a kernel bug and if so is there a way around it? Any advice would be great, thank you. It also seems like if the device is plugged in it wont even bootloop. It just stays at the black screen.

This could be the result of bad flashes and/or corrupt data carried over from your multiple flashes.
If so, you didn't mention anything about wiping data (sytem/cache/dalvik) in TWRP before each flash in your process, so that's most likely what's causing the issue.
Try those and also do a "fix permissions" after reboot as added measure.

sounds like your in fastboot?
try fastboot devices and see if it returns anything, if you get a number back then you are stuck in fastboot mode.
turn off kindle with usb cable attached, issue command bellow, when it says waiting for device switch on kindle, if fastboot kicks in it should reset bootmode.
fastboot 0x1949 bootmode 4000
or
fastboot 0x1949 oem idme bootmode 4000

So here is the point im at after following the tips.
I can get the device to boot one time on a custom rom. After the one time, dead. It doesn't show that it's in fastboot mode when it has the black screen.
When I get the 4.0 rom to load, adb or even usb mass storage mode doesn't recognize the device. Something really odd is happening and I have no clue as to what. Anyone else have a problem like this?

From TWRP:
adb shell parted /dev/block/mmcblk0 p > parted_output.txt
Paste parted_output.txt's contents here.

Kindle Fire. Device Manager Sees but Kindle Fire Utility Doesn't

My Kindle was rooted but I decided to try my hand at installing a custom ROM. However, the ROM I tried would not work and the screen stayed black. However, thanks to TWRP I could install Kindle from Amazon again. The installation went thru smoothly, or so I thought. Now, when I boot the Kindle, I see the Kindle Fire Logo and it stays there. The Computer can see the Kindle as an Android device, Android Composite Device. But Kindle Fire Utility cannot see it so I could try and re-install it again. Any suggestions?

Lacking information, so I'll just fill the voids with assumptions.
I *assume* you didn't wipe cache, dalvik-cache and most important when switching from a ROM to another, Factory Reset - this is the reason said custom ROM wouldn't work, and the reason flashing back update.zip (as you said you installed it, rather than restoring a backup) caused your KF to get stuck in a semi brick.
The most important question here is, do you have FFF installed?
If you do, fixing this is trivial. Just get into TWRP from FFF, wipe cache, dalvik-cache and factory reset and then install whatever ROM you'd like to try or use.
If you don't have FFF installed, then your solutions are to either get a factory cable (recommended) or to crack open the case and do the USB pin short trick. From there you can use fastboot to install FFF and boot into TWRP.
Alternatively, you can try "fastboot getvar product" or "adb shell idme bootmode 5001" to see if you get lucky.

During those few seconds I try recovery ... fast boot ...normal boot... n none seem to work . Kf just reboots n returns to boot loop . Any advice is appreciated .. thanks

What colour is the "kindle fire" logo when you turn on your KF?

Force Kindle into Fastboot
Ok, so I have finally got my Kindle to turn on, using the USB Short Trick. Now my only question is about getting the Kindle to boot into fastboot mode so I can re-format the sdcard partition and finally load a new ROM. I have tried several different commands and they all seem to miss the window of opportunity to start the kindle in fastboot mode. Is there any way, short of a factory cable, that one can make the kindle start in fastboot mode?

Not fastboot get var

fastboot getvar product doesn't seem to do the trick. The kindle seems to be in fastboot mode but the adb shell cannot access the device.

The problem is that you don't have the fastboot drivers installed (also, ADB will not work while fastboot is active) - Windows is painfully slow at detecting a device and installing its drivers, so by the time it even notices anything, the fastboot window is already over.
To solve this, use firekit: http://forum.xda-developers.com/showthread.php?t=1430038
The script that will probably suit your needs the most is usb_install_fff_twrp.

I have TWRP and FFF installed. However, upon booting into TWRP, the sdcard partition cannot be mounted, to the Kindle that is, and as such, I cannot mount the sdcard to the computer. When I researched this some more, I found that I can fix this by using a command via adb shell. The guide instructed using fastboot to achieve this. When would be the best time to use adb shell?

What's the output of partitions.txt? (type the following from TWRP)
adb shell parted /dev/block/mmcblk0 p > partitions.txt

Can't use adb

The problem at hand is using adb. I can never time it exactly right to open adb. I always get an "error: device not found". Windows even recognizes that Android ADB Interface is plugged in.

Okay, things are getting awfully confusing here.
What exactly is it that you can do and that you cannot do?
For example, are FFF and TWRP functional?

GOT IT!
Thank you! I finally figured out that the wrong driver had reinstalled and that was causing my computer to not be able to use adb shell. I fixed that and voila, I am now running CM9. Thanks again!

Please Explain Red Wipe Screen

I have tried several times to get CM 10.1 installed on my Kindle Fire 8.9 and every time I get the red wipe screen trying to install the 2nd boot loader.

I used this tool KFHD_SRTv2.1- 8.1.4 To get into fastboot when I had the solid red screen then used option 7 to completely wipe and restore their is probably another way to just do the boot but it did work for me (did it today even)
Turn the kindle off (hold power down)
Load the KFHD_SRTv2.1- 8.1.4 tool using run as administrator
then use option 1
once your kindle says its in fastboot then close that utility and run the First aid

I know you said you aren't on 8.3, but it sounds like the bootloader issue Hash talks about in step 4.5 of his post. You could try flashing the bootloader he posts in that step to see if that fixes your issue. I had the same problem, until I flashed it.
Just an idea, I am in no way an expert just a tinkerer.

I too have the red screen, I tried to use the SRtool but was unsuccessful in recovering, can u provide anymore information? i'm really freaking out a little because i'm new to this stuff

I think fattire said Amazon enabled fastboot in this state. On KF2 and KFHD7, this is possible with a factory cable. I guess it's also possible that they have enabled the use of the factory cable for the KFHD8.9, but I'm only speculating.
Before the update, flashing unsigned boot and recovery partitions without the 2nd bootloader properly functioning, the device just wouldn't turn on. Now, not only will the device turn on, but some are even fixable in this state. I'm wondering if Amazon realized that wasn't cost effective to send every broken modified device to a specific secure location to get reflashed.

I don't quite remember what I did, but I was able to fix the "red wipe" screen on my Kindle 8.9.
I think I got this when I first tried installing 8.9StariROM when it was first posted on the forum. I did not know that the red screen could appear if TWRP was not installed already, and I think that's why I got the red screen error.
I didn't really know what it was all about, but somehow I was able to make my kindle go into the fastboot using this command (fastboot -i 0x1949 getvar product) and basically followed the instruction here: http://forum.xda-developers.com/showthread.php?t=2128175
I kept getting device not found error on ADB commands, so I skipped to STEP 4.5 and ran below commands in order: (of course, I downloaded all those files as well)
fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin
fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.3.0.img
fastboot -i 0x1949 flash recovery kfhd8-twrp-2.4.4.0-recovery.img
then I think I ran fastboot -i 0x1949 flash system starirom-system.img to load the system image and I was able to have a working kindle 8.9 again.
I hope this helps.

Here is what I did to get myself out of trouble after screwing around with my KFHD 8.9 and getting a red screen (NOTE: I am assuming you have already installed the proper drivers so your PC can recognize the Kindle Fire HD):
1) Downloaded the above-mentioned KFHD SRT tool from here: https://docs.google.com/open?id=0B4lZEJI5lYeMR1YteUt2MGxZTGM) and the boot.img and recovery.img from here: https://drive.google.com/folderview?id=0B4lZEJI5lYeMNGdXMHI3T3pKM2c&usp=sharing
2) Unzipped the SRT tool into a folder on my Windows 7 boot drive (C:\KFHD_SRT_v2.1), and copied over the two .img files to the /images sub-folder.
3) Ran SR Tool.bat in Admin mode (right-click, Run As Administrator, click Yes to accept)
4) Turned off my Kindle by holding the power button 10 seconds until the screen was off
5) Chose option 1. Enable Fastboot, chose "n" when the tool asks if the device is turned on, then pressed the power button once on the Kindle to turn the screen on. Voilà, I was in Fastboot mode.
6) From a command line prompt (started in Admin mode as always), went to the /images sub-folder of the KFHD SRT tool and typed in the following commands, one at a time (just press Enter at the end of each, and wait until done):
fastboot -i 0x1949 flash boot boot.img
fastboot -i 0x1949 flash recovery recovery.img
fastboot -i 0x1949 flash system system.img (note: this may take a few minutes, depending on the speed of your USB port)
7) Still from the same command prompt, rebooted the tablet using the following command (type it in and press Enter):
fastboot -i 0x1949 reboot
I was back in business from there.

Can we get this as a sticky in the Dev Section? it took me 2 weeks to get my system back from a red screen that the below was able to do.

[Q] TWRP flash failed but firefirefire installed, now I can't get to fastboot mode

I've been trying to root my Kindle Fire running 6.3.3. I bought a fastboot cable and got it to boot into fastboot mode to flash TWRP and firefirefire. I ran the commands and TWRP failed but firefirefire installed. Now when the kindle boots I get the firefirefire bootloader but it cant boot into the recovery because the TWRP never installed. Also, I can't get it to fastboot anymore, not even with the cable. Can anyone please help me get TWRP installed? I've read many forums and tried about everything I found.

FFF bootloader supports fastboot commands, but the flash command is now
fastboot flash recovery file name
ie drop the -i 0x1949
Code:
fastboot flash recovery openrecovery-twrp-2.6.3.1-otter.img
because the fastboot mode window is short
with kindle connected to pc, power off kindle, enter commands, then power on kindle

I've been trying this for about 30 minutes or so with no luck...I even downloaded a different version of the twrp image. Do I have to wait for the fastboot screen to start the command or do I start the process before powering on the device? I'm not really sure what I'm doing wrong here.

Should be able to do it either way but I press enter, before the power button
This will not work if drivers are not correct
could try
Code:
fastboot devices
as a test should get something like
Code:
123456789 bootloader
back in command prompt

I finally got it to work and I can't thank you enough. You were right. I knew my computer recognized the device with adb in normal boot but my computer wouldn't recognize the device in fastboot mode until i reinstalled the android driver while it was in fastboot mode. Now I have a custom ROM running Google Play apps! Again, thank you!

Hey, I don't know if this will help others, but I had a hell of a time trying to get my kindle to recognize while in the bootloader/fastboot mode... It frustrated me so much that I had to write about it.
I recently switched to Windows 10, so it seems like my computer is relearning drivers and stuff...
My kindle was fine when on, and I could issue adb commands from the main screen, but when in fastboot mode, I couldn't get it detected. I knew the drivers were an issue, but I couldn't figure out how to do it. I looked at Amazon's support pages, went through the SDK route, tinkered with the adb.ini and so forth... to no avail.
Post after post said that the easiest way to install the drivers was through the Kindle Fire Utility, but for some reason, the drivers in the .bat file kept failing and would not load. It took a good few hours to figure out the solution.
When I asked the Web why the drivers kept failing, I came across a post that said Windows was actually blocking unknown drivers from loading onto my system. I really wish Windows had told me that instead of just saying "Fail"...
I had to hold down the shift button and click restart on the start menu, and when the computer restarted, I when through: troubleshoot -> advanced options -> startup settings and clicked on Restart. It eventually gave me the option to disable that signature verification [F7]
My explanation is crude, because I want you to look it up properly. Just search for "disable driver signature enforcement" and you should be fine.
Hope this helps others out. I may have to revisit my own post just to see how to do this again.

[Q] My fire won't exit fastboot

Hi, I was running CM11 on a rooted Kindle Fire HD 8.9 happily but decided to take the CM12 nightly and it's not gone well.
It installed but wasn't running correctly, here's where I made my mistake. Instead of waiting until I had a PC to hand, I did a factory reset on the kindle itself (i'm an idiot!).
Now, the kindle will start up into fastboot mode and take some commands but that's it. No recovery, no adb.
I have the android SDK installed along with google usb drivers and the amazon kindle usb drivers. The device appears on the PC (no yellow triangle, I'm running windows 8.1 and the driver is signed).
With fastboot, I can flash a boot and recovery image but I can't then restart the device in recovery mode or standard boot.
a fastboot reboot stays in fastboot mode. any volume and power button combinations won't take it into recovery.
i tried fastboot oem unlock but that doesn't get a response from the device.
I have the kindle SR tool utility (v 1.3.5). It can flash the images to the device but any attempt to reboot will always take it back into fastboot.
I've read countless articles but I'm now stuck. Have I killed my fire?
Thanks, Mike

"fastboot -i 0x1949 oem recovery" should reboot your kfhd into recovery. From there you can wipe system, recovery and data and re-install recovery, cm11 and gapps assuming the zip files are still on your device. Or you can erase and re-flash everything using fastboot commands. If all else fails you can first return it to stock KFHD OS using the system recovery tool. All you need is to get it into fastboot mode which it sounds like you can.

In my situation (Kindle fire HD 8.9 amazon OS 8.1.5) after install TWRP 2.6.0.0, the device is not loaded (always orange logo kindlefire at all) me helped Wipe> format data, after I then sent image cm-11 for devices, `adb push cm-11.zip /sdcard/`, and wipe cache and install cm-11 are successful.
Installing TWRP only for fastboot mode, in the fastboot mode `adb` command dont work, only `fastboot...........` command.
I hope something helped.
