Hi everyone,
I attempted, and succeeded, at installing a 2nd-Bootloader + TWRP using the complete guide found in these forums. Afterwards, I was able to boot into TWRP but the Kindle itself would not boot, just sat on the blue "fire" logo. I first tried to use the KFHD_SRT_v2.1 to recover, but that resulted in where I am now, just the standard orange Kindle Fire logo (no blue) and nothing beyond that. I then tried the Kindle Fire First Aid tool to perform a "full restore", which appeared to be successful, but again with the same result; it just sits on the standard Kindle Fire logo. I've let it sit, and waited, for upwards of half an hour after each tool, it won't budge.
At this point I can get into Fastboot using the command prompt: fastboot -i 0x1949 getvar product
And the info does show up correctly. So I assume this means my device isn't complete shot?
After a few hours of poking around, I learned how to use various fastboot commands to push stuff into the Kindle, and it seems to respond. However, I can't, for the life of me find the stock Kindle partition files anywhere on the internet. If I understand correctly, I need the bootloader partition (.bin?), boot partition (.img), recovery partition (.img), and system (.img).
Help??
I don't recommend flashing the bootloader partition in this scenario, mainly because in doubt it is damaged and a bad bootloader flash can kill your kindle. What needs to be reflashed is usually recovery, system, and bootimg. Kffa downloads them off the net and stores them in a folder, SRT comes with them.

Thanks for the info stunts. I did try both SRT and KFFA, with the same negative result, but I did not know that kffa stores these images locally.
I went ahead and extracted the boot, recovery, and system images from kffa directories and manually flashed them in fastboot. And it worked!
Which still leaves the question as to why the tool itself didn't fix my issue when it had the resources to do so? strange, anyways thanks! :good:

Hello, I have a rooted Kindle Fire (with bootloader) and tried to return it to original Amazon Stock OS.
I tried the steps specified on this page androidcowboy.com/2013/06/how-to-return-kindle-fire-hd-to-stock/
After this steps:
"Navigate to the folder where you unzipped the Kindle Fire SRT Tool and double-click on “SR Tool” file. Choose option 1 for “Restore-Factory Rooted with Superuser.apk”. Be patient as it’s very important. The file transfer can take up to 5 minute with no progress notification. If you interrupt the process in any way then you will BRICK your device. After the transfer is done then choose option 4 to “Erase cache and userdata”. Once it’s finished then choose option 6 to reboot."
It rebooted and seemed to be stuck at the white and orange Kindle Fire logo screen. I can turn it off and on by holding the power button, but my computer cannot detect it as a portable device or ADB. But I can enter fastboot mode by plugging the USB while it is turned off, so I don't think it's hard bricked.. I hope so.
Any thing wrong that I have done? Sorry I'm a noob when it comes to this. Help please?
Btw, my Kindle Version 8.4.1
Is it boot looping on the animated kindle logo or the static image one? Cause either way I'm guessing something went wrong with the flash, you should probably reflash the boot and system images, try using kindle fire first aid if the SRT doesn't work, I believe it has a stock rooted image flashing option like SRT. BTW don't confuse boot with bootloader, boot is where the kernel is stored. Just pointing this out because if you don't need to flash the boot loader then u shouldn't, if it corrupts you have a hard brick.

I do have KFFA, which option should I choose? And mine is stuck on a static image one.
Weird sounds like it doesn't want to even try to load the os, maybe some things wrong with the kernel, anyways I haven't ever used kffa, but there should be an option somewhere to restore system image. You will first need to get the device into fastboot mode, just open a command prompt and CD into the kffa directory, I should have a fastboot command, and run this: fastboot.exe -i 0x1949 getvar product
Then plug your kindle in with the power off. If for some reason it doesn't work, which it should because you seem to have flashed something from fastboot before, then u will just have to update a driver before it disconnects.
Edit: OK fixed sorry for the thread mix up.

Same problem
I have a KFHD 8.9 with the same problem as the OP. It's stuck on the static (orange) Kindle Fire logo. I have working drivers and I am able to get it into fastboot using "fastboot.exe -i 0x1949 getvar product". The problem is, I don't know any of the history of how it got this way. I have repaired a lot of Generation 1 KF's and I thought I would get started on the Gen 2's so I bought this on eBay this way. I didn't realize how much more risky it was to work on the Gen 2. I also have KFFA working but I can't figure out how to get the stock image onto the KF so I can flash it back to stock. When I go into fastboot mode and use KFFA to reboot to normal more it just stops on the static Kindle Fire logo. Also, I can't get ADB to work at all. Any help would be greatly appreciated.
There's an option in kffa to restore the system partition, should be a fairly obvious choice, if you can't find it try the kfhd system restore tool

Well I tried KFFA Option 7 - Completly Restore the KFHD 8.9 8.1.4 (Fastboot) but it didn't work. There is a problem in RunMe.bat with the wget command when trying to download the .img files from dropbox:
Connecting to dl.dropboxusercontent.com|174.129.21.126|:443... connected.
ERROR: cannot verify dl.dropboxusercontent.com's certificate, issued by `/C=US/O

Unable to locally verify the issuer's authority.
To connect to dl.dropboxusercontent.com insecurely, use `--no-check-certificate'
Unable to establish SSL connection.
So then, I Downloaded the KFHD_SRT tool and managed to restore the system partition but it still would not boot. Then I saw down at the bottom of the instruction page that to downgrade to 8.1.4 you also need to restore the boot and recovery partitions. After I did that -- PRESTO! my KFHD 8.9 booted up and is now working.
THANK YOU SO VERY MUCH FOR THE HELP!!!!! I will be sure to click the "THANKS" button.

Hey, I got same problem, after I install a bootloader for my KFHD 8.9, the original Kindle OS was unable to boot up, I got 8.4.6 when I recived my KFHD, Is the problem of OS ?
Sorry, but after re-reading my post I realized that I probably gave bad instructions. Mods please delete this post...
So I bought a 8.9 KFHD Demo unit. I gained access to fastboot through command prompt and have all the drivers installed. Stupidly, I used the KFHD System.img Recovery Tool for the 7 inch model on it and subsequently it boots up and says Kindle Fire for a few second, a red screen washes over, and then it says fastboot and stays that way. I then proceeded to erase cache and used the KFHD System.img Recovery Tool for the 8.9 inch version, the one I have. Sadly, it proceeds with the recovery but my kindle is still stuck booting into fastboot mode. Anyone have any ideas? Or did I break it for good.. Thanks for any help
You try "fastboot -i 0x1945 reboot"?

I think you meant 1949, and yah it just reboots it and it boots into fastboot mode, plugged into my PC or not.
Edit: I also saw your other post in a similar thread about restoring stock boot loader but requiring the check of md5sum... was going to try that but wanted to ask if I am checking that the md5sum of the stock bootloader is the same as the one i am downloading?
Well that's one way to look at it because they should be identical if its the same version boot loader, but the md5sum is supposed to match the md5sum listed on the download. Also yes I made a typo in the previous post, thanks for pointing that out. You can also try something like "fastboot -i 0x1949 oem idme bootmode 1". For the record I don't remember which idme number is normal boot on the 2nd gen devices. The original kindle fire's had a different set of numbers for idme, but I believe the 2nd gen kf's use 0-3, so you might have to try a few numbers to get it right. I looked it up somewhere before and I believe found which one was supposed to me normal boot, but I don't believe i can look far enough back in my posts to find it via the xda app I'm using.

Neither 0-3 do anything, on my kindle. Although, each one says finished in the cmd prompt. Should I go ahead and tr flashing the stock loader on? or should I of done that before trying your line of code.
You didn't necessarily need to flash the boot loader beforehand, and did it reboot after issuing the command I mentioned? If not did u try a simple fastboot reboot afterwards like I Initially said to do? You just need to be careful if you are going to flash the boot loader, like I said make sure to check the md5sum and of course make sure its the boot loader for your model.

None of those commands did anything but I did do the reboot command and it rebooted back into fastboot mode. I guess I will try to flash the stock bootloader now...
So after trying different recoveries I have gotten my kindle out of fastboot but now it is stuck on the Kindle Fire System Recovery screen asking me to reboot or reset to factory defaults because it failed to boot(neither option fixes it). I tried the KFHD System.img Recovery Tool to no avail. Not sure what to do now. Do i need to flash the complete stock OS to it?
I used KFHD First Aide to get to this point. After I use it though, on the recovery screen I get a bunch of errors saying it can't mount cache. On the KF First Aide bat file prompt it says it erased cache, then attempted to format it but it's not automatically formatted as the file system type is not supported. I am wonder is these things are related.
Try running kffa one more time, it usually goes to recovery when something is messed up with the system partition, so try another reflash.

Same thing happens. Says it didn't automatically format userdata or cache and then when the kindle boots it goes to recovery and the errors says" E:Can't mount /cache/recovery (Invalid argument)
because kffa downloads the files it flashes do you think those were corrupted? It only downloads them once so when i run it again its flashing same files.
Ah well that could be the case, but this error seems to be an issue with mounting the recovery partition which is weird because recovery seems to work fine, at least I think its trying to mount recovery, though that is in the cache path so I have no idea. Might have to ask soupmagnet about this.

hi I have the same problem you once had I have kindle fire hd 7 I two am in this boot then red screen then stuck in fastboot how did you fix this any help would really help me many thanks
You should try reflashing the bootloader, just make sure you grab the right bootloader for your device and check its md5sum against then one listed on the download. If you don't check the md5sum you are liable to hard brick it. From there it should be as simple as flashing the rest of the partitions from fastboot and hoping it works.

I got a KFHD 2G (2013) from a friend and the problem was simple: when the lock screen came up, he couldn't enter in his passcode because the keyboard wouldn't show up. There was no way to get into ADB since I couldn't get in. I tried to do a factory reset via recovery, but there is no recovery. I built a fastboot cable and tried "fastboot -w" but the partitions could not be formatted. This device seems completely screwed, I trued grabbing the factory update from amazon, but it's in BIN format and won't flash in Fastboot. Inside the BIN file, it seems to just be a recovery-flashable zip, however, it will not boot into recovery so i can't install it. Fastboot reports that two .txt files are missing. I tried extracting recovery.img from the zip and booting it as a ramdisk, however, this just causes it to boot normally. I ended up flashing userdata with boot.img as a way of formatting it, which got the keyboard back, but puts it on a screen saying "Enter password to decrypt Kindle." The password, "LOVE" is not accepted and entering 4 incorrect codes does not prompt a format. I'm at a loss here, it seems like it's just nt possibe for this thing to be screwed completely, but im out of options. what should i do?
HELP!!!
Also, I just realized this thread should be in "7" Kindle Fire HD Q&A, Help & Troubleshooting"
Um so now it's to the point where it's asking to format it because the password is wrong so wouldn't that be the same as formatting it as you had intended on doing earlier? BTW fastboot commands on a kindle fire have to be prefixed with "fastboot -i 0x1949", also I don't know off hand if that command you were going to run is a user data wipe or a complete wipe and a complete wipe would been bad. So at this point if the lock screen asks you to format it and you don't have adb enabled then you probably will have to format it, I thought the new gen had adb access from early on in the boot process but I could be wrong, I suggest looking in the hdx section.

sadly, no adb, its not an HDX because it's only dualcore. i now need a system.img and userdata.img.. i flashed the img from the ADK for this device and now all i get is fastboot.. i need ripped imgs from an actual device. the command i was running was a userdata/cache wipe, and i did prefix it but fastboot couldnt format the partitions because the filesystem wasnt compatible. The lock screen flat out wouldnt ask me to format, and the back button never showed up, which leades me to believe the system image was corrupt too. if anyone can give me system.img and userdata.img i would be eternally grateful! thank you for replying
Ah I knew it wasn't an hdx but they some things on that device that are similar to the hdx, like I think they disabled some fastboot commands from working and such. Hopefully someone more familiar with 2nd gen hd's can help you out more.

so i borrowed a friends kindle and backed up his /system. i then sparsed it and it installed fine. when i booted up, i got a red flash and it threw me into fastboot. i then flashed the u-boot from the update file and now im bricked beyond all reair.. i run lsusb and get no mention of the device with my factory cable, and i cant get back in fastboot. the 2nd gen hd's suck so much..
Ouch, was his kindle a second gen HD?

Bricked KFHD 8.9in
Can get device into fastboot if I type "fastboot -i 0x1949 getvar product" but only if I enter the command immediately when connecting the device.
I tried doing the process manually by getting it into fastboot and then immediately entering "fastboot flash recovery /Users/USER/Downloads/KFHD_SRT_v2.1/images/system2.img" but it says <waiting for device> as if it weren't connected.
Any ideas?
Well that is the wrong command... In that command you tried to flash the system image to the recovery partition... Replace "recovery" with "system". Also every command has to have the ”-i 0x1949” or it won't work.

Hello,
Without beating myself up, here is what I did:
1. used steps from another site to root my Kindle Fire HD 8.9 and attempt to load Android 4.4.2 on it. First major mistake.
2. during that process, the steps to make a backup didn't work and I continued. I realize that was my second major mistake, one from which I cannot recover.
3. attempted to use a Factory Image found on this site. I followed the steps, and when I perform the "fastboot -i 0x1949" reboot command, I get the "kindle fire" orange logo, and it sits there. I'm guessing it's bricked.
4. without giving up, I attempted to follow the commands found on this site here (http://forum.xda-developers.com/showthread.php?t=2128175), but I've been unsuccessful.
So, I'm stuck looking at the "kindle fire" orange logo. My thoughts were to get an image on the device and boot into it to at least get all the necessary files for flashing the image. Nope. I would appreciate any assistance. I will also state that I am a very fresh NooB when it comes to these things. I thought I was prepared, but I guess not enough.
TIA!

if you never installed the fastboot drivers that would explain the issue. when the kindle first turns on after you plug it in while off, it should briefly be detected as a jem device in the device manager. if it already has the drivers installed it will briefly show up as a adb device. if you don't have the drivers installed then grab the ones from mg SIG and extract them somewhere and point the update driver box to it in the few seconds it is detected. once it is installed power the kindle off! run the "fastboot -I 0x1949 getvar product" and when it says waiting for device, plug in the kindle while it is off, it should go into fastboot.

OK. I followed your instructions and installed the driver. I then attempted to install a base image following the instructions here:http://forum.xda-developers.com/showthread.php?t=2011126
I chose the following prompts: 1. enable fastboot, then 2. Restore-su/supersu.apk only, then 4. Erase cache and userdata, and finally Reboot normally. No luck.

All I have are whatever people have shared. As mentioned in my initial post, I do not have a backup of what I had before I started. Perhaps my biggest mistake. My understanding is that I need to get the Kindle software back on it in order to install the Android bits. Perhaps I am in error on that thinking. Please let me know if that is an unneeded step.
Use either kindle fire first aid or system restore tool and stay away from kindle fire utility unless you want a paperweight.
