[Q] Installing 2nd Bootloader led to Kindle not turning on - 7" Kindle Fire HD Q&A, Help & Troubleshooting

Hello,
I recently asked about how to root the kindle fire hd 7 (2nd generation), which I got to work. I was able to root it and start messing around with it.
I wanted to flash a rom onto my kindle, but after following the steps on this tutorial: http://forum.xda-developers.com/showthread.php?t=2128848
the thread said if everything was followed correctly, then you wouldn't have a problem. I did follow everything as far as I know, but when I waited for the reboot part of installing the bootloader and stuff, it simply stayed black.
I have tried turning it on and charging it and other things, and it just doesn't come on. I figured I could reinstall the partition back to FireOS, but I can't even get to fastboot in the first place unless it's able to turn on.
Any help with this?

You probably hard bricked it, the 2013 models can't have twrp+2nd bootloader on them, the exploit isn't compatible, so if you downgraded the bootloader to one from the previous generation's kindles, then you hard bricked it.

Is there no recoverable form of hard-brick?

I don't think we have the process completed yet, but more or less it involves soldering a sdcard reader to the kindles emmc contact points on the motherboard, i think someone was mapping them out but hasnt mapped them all out yet. The process to map them out involves taking the emmc off the kindle so not too many people are into doing it. But the actual fix is not that complicated, you just have to be decent with a soldering iron, and flash the original bootloader from a linux os like ubuntu. It's been done on the kf2 and hd 8.9" models.

[Q] 7.3.1 auto installed, I lost root, having other issues...help

I was rooted on 7.3.0 from the day I got my replacement kfhd less than a month ago. I forgot to turn off automatic updates and yesterday 7.3.1 installed and immediately I'm having problems. Some apps I had installed are gone, like No Lock and Apex Launcher (I'm almost positive that's which one I was using) for starters. I tried to reinstall No Lock since I have Nova Launcher working and I'm sick of unlocking twice. Downloaded No Lock, went into ES File Explorer to move it, and there is NOTHING in /data/app to move.
I'm almost afraid to see what other problems there are. I downloaded a root checker and it says I'm not rooted anymore. Well that explains a lot. However Google Play has hung around problem free, which you did need root for.
How should I proceed? I fried my fiancee's kfhd a month ago after I rooted it. I was attempting to install TWRP, screwed up, and bricked it. She went out and bought another tablet. I called Amazon and told them it just died for no reason so they sent a replacement which became mine. If I brick another kfhd I don't think Amazon is going to want to replace it again.
I know 7.3.1 was just sent OTA and not to everyone a few days ago (found that info on the forum somewhere) so has anyone re-rooted after getting it? What other things can I safely try?
It might seem kind of obvious but why not simply root again? I don't see any reason why it wouldn't work. I rooted my KFHD running 7.2.3 with Kindle Fire First Aide no problem. I'd imagine that 7.2.1 should be no problem. If you follow the steps in this thread it's pretty easy.
Also I should mention that it's pretty difficult to really brick your KFHD. If you get a factory cable (either make one yourself or order one from SkOrPn on here for pretty cheap) you can almost always fix any software problems. The factory cable essentially puts the KFHD in "factory" mode which lets you flash it in fastboot almost regardless of anything you've manage to damage. I messed up my KFHD pretty bad (stuck at the boot logo and would refuse to be be detected at all via usb) but with a factory cable it was super easy to fix.

Rooting it again would probably work from what I know about rooting phones. I'm kinda hoping someone else has already done it so I know for certain that it's gonna work before I do it.
Maybe I have to be the person who finds out if simply rooting again fixes the issue.
Rooting again should fix the problem. I would try that first.
Worst case scenario it doesn't help and you have to do a factory restore or re-flash in which case you can simply restore a clean copy and then either disable the OTA updates or else, better yet, let it update all the way to 7.2.3 and then root the latest version.
Yeah, I think I'll give rooting it a shot. I PM'ed the guy that made the Kinology 7.3.1 ROM about rooting and then flashing recovery from where I'm at right now since I can't post in the “development" forum until I have 10 posts. He also said it should go fine from where I'm at. I'd love to flash that ROM, I'm just afraid of screwing up since I massively screwed up the first time I flashed a recovery.
I'll give it a shot tonight when I've got time to mess with it.

It's not hard as long as you follow the instructions... It works flawlessly on mine.
Well I'm happy to say that rooting again after the 7.3.1 update Amazon snuck in on us went perfectly. So when others get that update and aren't sure if they can root again easily I hope they see this thread and know that it is no different than the first time you rooted.

My only concern is messing up the TWRP install. If I actually read the instructions a few times before doing it I shouldn't mess it up this time. I'm gonna look into it some more this week in my spare time and convince myself to do it. The extra encouragement of it working no problem is appreciated.

[Q] Bricked? Kindle logo for 2 secs then red.

Hey guys,
Firstly many thanks for the help!
I rooted my Kindle Fire HD 7" successfully using KFFirstAide, worked fine.
I then selected option 10, to install second boot loader, TWRP. seemed to work fine. But now all that happens is the White and orange kindle logo shows for a second, and then the screen turns all red.
I'm assuming bricked :/.
Now my question. Will the factory cable that I can purchase help?!
Many thanks,
Mattt
Yes it will, from there you just need to reflash the stock bootloader. I don't know if kindle fire first aid has the option to restore the boot loader but if it doesn't theirs instructions mor or less in has codes thread on manually installing the 2nd boot loader. The instructions were designed for downgrading the boot loader, but they also fix a bricked kindle by restoring the file he included. If u can't find anything in the of first aid then use this link.

Look underneath where it says "added 04/02" in red letters towards bottom of first post. Make sure you check the md5sum so u don't hard brick your kindle.

Thank you so much for your reply Stunts. I've just gone ahead and ordered the cable.
I think there is a restore option, but that was for the three partitions. Is that what I need to restore?.
Many thanks again I'm sure i'll have some more questions when the cable arrives!
Cheers,
Matt
I haven't bricked a kindle yet so I am not sure what partitions it backs up, I think it backs up boot, system, and recovery. If that's the case I don t think it will help but I am unsure. I can always download kffa and look through the batch coding to see what it does though if I need to. I'll look through the coding tomorrow to see, I don't have the mouse to my PC with me and its a pain to follow scripting on a tablet IMO.

Matt,
I was in the process of flashing CM10.1 to my Kindle the other day and I encountered the same problem with the red screen. I had forgotten a step. All I had to do was do was exactly what Stunts said, in the step under "added 04/02" (in red letters). You use the fastboot cable and the Kindle in fastboot mode to push that file onto your tablet.
Once I did that, the red screen went away.
You guys are amazing, thanks so much Stunts and calkenneth!
I really appreciate the help!
When the cable arrives I'll flash the boot loader from there, hopefully that will unbrick and I'll carry on from there.
Just one question, is the bootloader, the same as what is effectively stored on the root partition / ie the root backup img.
Thanks again guys!
Um if I am understanding that correctly then no is the answer I think. I am a Linux user so I understand the root partition, not sure where the boot loader itself is stored, outside of the actual block that I think we can backup off it. I don't think its a mountable partition, though if it was I wouldn't mind perusing it in read only mode. I just personally haven't seen it.

HUGE thanks to both you guys!
Cheers so much stunts and calkenneth. I did exactly as you said. The cable arrived, fastbooted the boot loader and all was good!
Managed to install Andriod and Google Store. Now it's working like a charm and I'm loving it.
Thanks again!
Excellent, glad to hear it!

[Q] Possibly Bricked KFHD 7"?

Hi,
I think I might have bricked my Kindle Fire HD 7". I successfully rooted it using B1nary's tool (v17) and went about trying to install TWRP. I used this guide:
gizmodo.co.uk/2013/04/the-simple-guide-to-root-the-kindle-fire-hd-and-flash-a-custom-rom
Sorry for the lack of direct links - it's because I'm newly registered
I started having trouble around Step 2, with the adb shell commands not working. So I tried another method, and came across this one:
liliputing.com/2011/12/how-to-install-twrp-2-0-touch-based-recovery-on-the-kindle-fire-backup-restore-flash-custom-firmware.html
Stupidly, in my haste I neglected to read the fact that this tutorial is for a Kindle Fire, not the Fire HD. I got to the final step, step 11 - switched off my KFHD and now it won't start up again. I have a fastboot cable bought from eBay but I'm not sure if I've totally screwed my device or if it can be fixed. Due to the fairly incompetent nature of my fault, I haven't been able to find a solution via searching XDA or other forums, either.
Any help much appreciated.

Yea, flashing anything meant for another device is almost a certain hard brick. when you plug your device into a USB port with a fastboot cable, does it enter fastboot? If it does, you can try a a system restore. If it does nothing, that's it for the device.

It does nothing. Diddly squat. Oh well, I guess I'll just chalk it up to incompetence experience....and go buy a Nexus 7 or Galaxy Tab 3 :-|

[Q] [Help!] kindle fire HD won't boot past first words saying Kindle Fire

I've been living (mostly) happily with my Kindle Fire HD 7" running BAM rom (the best rom ever) for a couple months now. I decided to upgrade to android 4.4. I went into TWRP to install the new rom, but it wouldn't install, so I decided to flash one of my recoveries I had made in october and it flashed it fine, but when it boots up now it won't even get to the blue Kindle Fire anymore, it's just a boot loop BEFORE it.
When I first did this I had basically no clue what I was doing so I didn't make sure that fastboot was working and it doesn't seem to be working now.
Please HELP!!!!

I had this happen to me recently. It's easy to fix, with the right tools. You need a Fastboot/factory cable (whatever you want to call it) that has a short from pin 1 to 4, and Kindle Fire First Aide (In the KFHD 7" General forum).

You don't necissarily have to buy one--I built one myself (with a little help from my dad). All you need is a spare Micro-USB cable, a soldering iron, a small strand of wire, and a bit of battery power left on your Kindle. If you want to make the job a little bit easier, you can also get a Micro-USB breakout board from SparkFun.com. They're so much easier to solder to than a plain Micro-USB end.
Tutorial I used: http://chimerasaur.us/2012/01/making-a-kindle-fire-factory-cable/
For the breakout board: https://www.sparkfun.com/products/10031
hey, was able to use a single wire to temporarily turn my normal usb to a fastboot usb:cyclops:, but now what do I do?
Don't know what's happening!!
I flashed a new system, boot, and recovery, but it still will boot up into boot loop. WHAT DO I DO (I do know how to do fastboot using -i 0x1949 so I know that's not my problem I'm thinking bootloader, but am not sure)
tried flashing bootloader...
Didn't work!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I'm a little irritated. downloading a program(forgot it's name) that's supposed to be able to flash the proper files to recover a fully bricked device, so I'm hopeful:fingers-crossed:

No such tool exists for the KFHD. What ever you're about to use is gonna hard brick your tablet. Use the system restore tool for Kindle Fire 7 and run the bat tool or push the images. Read the tutorial to get some background knowledge on this.

So what was the name of the program you used?
What was suggested earlier
After posting some of my previous posts, I realized I somehow had kffirstaid and used the restore option (but I personally like to manually do the fastboot commands, so I used it mainly to download the files and do it the first time) then redid the steps in this forum to get it to reinstall twrp and then flashed cm11.

Help KFHD7 Won't turn on

If anyone could help, i'd really appreciate it. I was successfully able to root my kindle, but after rooting i tried installing TWRP via adb it never came back after it's final reboot. I have a fastboot cable and even with it, the kindle won't turn on, doesn't show up in devices on either linux or windows. Does anyone have any ideas how to recover it? I'm thinking that the bootloader is somehow missing or corrupt in a way that even fastboot doesn't work.
Also, if it is not recoverable in it's current state, is there somewhere that i can get a replacement system board to get it back up and running. I'm very technically savvy and am completely comfortable changing system boards, i'm just not familiar with android bootloaders enough to know how to fix this.
If it hard bricked, which it probably did, you can either replace the board or wait for kurohyou to map out the emmc contacts on the motherboard like he did the kfhd8.9 and kf2, and you can do some soldering and reflash the boot loader from Linux. Otherwise replace the board.
