[Q] 7" kindle fire HD boot loop

My 5yr old son was playing with a stock kindle fire and brought it to me saying it stopped working. He was correct because now it is stuck in a boot loop at the kindle logo. Is there anything I can do to fix it. Sorry in advanced if this has been a topic before, at work not much time to search. Any help would be appreciated thanks

You need a fastboot cable and the system restore utility. Here's a link to the utility:
http://forum.xda-developers.com/showthread.php?t=1951254
Once u have a fast boot cable just ignore step 2 on that link, its kinda confusing but your fast boot cable basicly does what step 2's commands do, but those commands require the kindle to be fully booted.
Also wanted to check since I have seen a few rogue posts, is this a kindle fire 7", 8.9", or kf2., or somehow a kf1? That link I used is for HD 7" so if its another kindle please tell me or it will brick it further.

[Q] fastboot will not work, no other thread helped yet

wanted to convert my HD7 into full android and got red screen in process. have read dozens of threads so far no help.
have fastboot cable, and I can get my kindle screen to say fastboot kindle fire - but I cannot seem to get the proper driver installed on my Win8 so that I can use fastboot. I've downloaded and installed numerous drivers. So far my kindle will not communicate with my computer, thus I cannot move forward in any way. I have installed ADB and SDK on my computer. I have scoured internet for ideas, helps. I am STUCK. Any help greatly appreciated!

Try the driver on my signature, but take note you are on windows 8, you can't install the driver by default because windows 8 won't allow unsigned drivers, you have to boot windows 8 up with driver signature enforcement disabled. Google disabling that and I think it may be the root of your problems.

Thanks! I think it worked. I still can only see my kindle in device manager, but I ran the SR Tool.bat option to check fastboot and it said it finished. of course my kindle won't reboot or anything because the bootloader is messed up. so now I am on a quest looking for steps to flash something with fastboot so that my kindle will actually reboot and then I can take steps toward a completely new ROM. obviously I'm learning as I go. I'll start reading more threads, feel free to point me in the right direction if you want. thanks again!

Do the part at step after where it says added 04/02, and please make sure you check the md5sum of the file before flashing, if it doesn't match up you will have a hard brick. Just Google "md5sum windows" if you don't know how to calculate a md5sum on windows. There's freeware available to do it.

I've read threads and answers to the point now that I'm going in circles. No one seems to address my problem. I am in fastboot. It appears I can flash things onto my kindle. I got the "kfhd7-u-boot-prod-7.2.3.bin" file on my kindle and got rid of the red screen. but I cannot get a recovery screen on my kindle. it just says kindle fire (fire is in orange). I press the power and volume up button and nothing. I go back to the beginning, read more threads. argh! it doesn't seem to be bricked. I just can't get a new bootloader to run so that I can flash a new rom. argh help!

You can't get into twrp anymore be cause we had to restore the stock boot loader, now u just need to reflash the system image and it should boot up, might need the boot image as well, but I think that kfsrt restores both of those, just put it in fastboot again and start the process.

It was a long haul but finally got out of the loop. thanks for your help! the final step that got me out of the ditch was to download and use the KFHD_SRT_v1.3.5- 7.3.0, then I ran #3 restore-factory recovery. I learned a lot through the process about fastboot and flashing files. For now I'm rooted with factory launcher and some other options too. I still think I want to wipe it and make it totally android.
Thoughts or recommendations? and thanks!!!!!!!!!!!

Well there are a fair amount of ROMs out, I use a tablet ui cm ROM that jester originally made, but when he went straight to cm 10.2 I wasn't ready so I made my own patch for cm 10.1 latest update with tablet ui, if your interested check the link in my signature out, though u need to put twrp back on again.

Bootloop Between Blue and Yellow Kindle

I posted this late last night after spending hours troubleshooting so sorry for the lack of details.
I thought I followed the instructions to a t on this thread. The only step I skipped was backing up my data. http://forum.xda-developers.com/showthread.php?t=2128848
When my Kindle Fire HD booted, it would loop between the regular Kindle Fire logo and the Blue logo. Eventually it would then go to TWRP. Once in TWRP I tried numerous times to use the Boot Option, Restore Option, and Recovery option to no avail. When I selected Bootloader, I would get the fastboot logo and it would stall there. I had to hard reset to get it to start again. Every time I connected my Kindle to the fastboot cable and entered the ADB or fastboot commens, it would say waiting on device. I also tried using the Factory Restore tool below and that did not work.
http://forum.xda-developers.com/showthread.php?t=1951254
When I connected the Kindle Fire HD to the PC, sometimes it would show as Android Device and other times it showed as PVT-8 or something to that effect.
Here is where I am now. The Kindle Fire HD no longer can boot to TWRP. It just looks the normal Kindle Fire logo and it loops indefinitely. My PC can no longer see the Kindle Fire HD at all. Is this a true brick or do I still have a chance?
BTW, I have multiple micro USB cables for all the devices I use. I am pretty sure the one I am using is the factory. How can I confirm this is a fastboot cable?

How did you get back to an orange only boot loop, it was easy to fix when it was blue... If it only is orange you are probably going to need a fastboot cable. Oh and to satisfy you with an answer as to why it boot looped, its because the newer amazon os detects the older boot loader or twrp, and refuses to boot, so you have to have a ROM ready to flash on the sdcard ahead of time.

Thanks. Anyway to confirm that the cable I have is a fastboot cable? Also, how would I go about performing a repair if it is.

If its a fastboot cable you would know it because you bought it for such occasions and because as soon as you plug it into the kindle it says fastboot in big letters. Once you have it in fastboot use kindle fire first aid and try a system reflash, I'm sure it would boot up without a doubt if you used an older version of the Amazon os, like I think 7.4.2 or older, but I don't know what version kffa uses, so if it still doesn't boot after doing that, try using the kindle fire system restore tool.

Thank you. Much appreciated. I ordered one from Amazon but will see about making one myself.

Are you trying to boot into Stock Amazon OS? That's your issue. Download a ROM and proper Google Apps package and either put them on your SD Card by mounting USB Storage in TWRP, or sideload flash a ROM, then you'll boot without issue. Don't forget to factory reset and wipe /system beforehand! I had this same issue my first time.

He somehow got rid of second boot loader, so he can't get into twrp...

If you are going to make one yourself find a Samsung branded cable they have the necessary solder points the rest of them don't seem to

I have the fastboot cable now. It will go in to fastboot as soon as I connect it. I tried using the KFHD Recovery Tool but I am still stuck in a Kindle Fire loop. Any ideas what to do next? I chose option1 and 3 already from the tool.

Why option 1? That is a different version of the tablet. You want to run KFFA and select 'completely restore the KFHD 7 7.2.3' This should be #3 of KFFA.
So once you have the tablet in fastboot, just run KFFA and go from there. Some files will download and then KFFA will push them onto your tablet. After that, your tablet will be stock and you can root and remove OTA updates from there. Keep an eye on your computer screen as the script will tell you what's going on.

I have never bricked anything as bad as I bricked theis Kindle Fire HD 7in

Okay so I bricked it bad. We're talking BAAAAD. No boot, to any screen at all. you press the button and nothing happens. Nothing happens when you plug it into the charger either.
I was following a tutorial on youtube (its the first link you hit when you youtube "flash kindle fire hd android", by zedomax) and I got as far as this code:
fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.4.3.img
fastboot -i 0x1949 flash recovery kfhd8-twrp-2.6.0.0-recovery.img
fastboot -i 0x1949 reboot

and the moment I hit enter (after the reboot part), bam, It went black, and has not lit up since.
SO, gentlemen, how did I do this? how do I not do this again? And, anyone have any ideas on how to unbrick it?
Thanks

Do you have a Fire HD or Fire HDX?

You flashed a Jem to a Tate (KFHD 8.9 to a KFHD 7) Sorry to say that is a hard brick. Someday there may be a way to install the drivers but right now it's done. Sorry.

I figured. For future reference, is there a way to flash it to droid? How would I go about this next time?

I would use fireflash and check the box to downgrade the boot loader. There's a tutorial by seokhun in the kindle fire 7" android development forums that's stickied. Still kinda confused how those commands hard bricked it, you only flashed the kernel partition and the recovery partition, I figured the boot loader would at least show up and stay in a bootloop since those partitions aren't signed and they are the wrong versions. If you can return it for a new one I'd do that, just tell them it won't turn on and they should replace it if its under the warranty from time purchased still.

He flashed fhd8-freedom-boot-8.4.3.img to a KFHD 7. Wouldn't this cause some problems or no? I know it's just the image but it can't do pushing it the same.

Kindle Fire (1st Gen)

Hello,
I have a Kindle Fire (2nd Gen) running on firmware 7.4.6, is there a tutorial on how I can root and run another OS
instead of the Kindle OS?

Use this to root it. http://forum.xda-developers.com/showthread.php?t=1886460
Use this to get 2nd boot loader + twrp installed: http://forum.xda-developers.com/showthread.php?t=2271909
Two important things you should note, one is put the ROM and its corresponding gapps on the kindle's sdcard ahead of time or you may suffer a boot loop and have to push the film manually into twrp. Second is when you open fireflash, make sure to check the first check box, it should have red warning text under it. If you don't check this box you will reboot to a red screen and it will require a fastboot cable to fix. BTW you might wanna fix the thread title since this is a kfhd not a first gen kf1. Only reason I can tell is because of the os version. Kf1's have a completely different method to root and flash since they don't have a high security processor that checks the boot loaders signature.
