[Q] kf2 stuck on boot logo - Kindle Fire 2 Q&A, Help and Troubleshooting

ok - so third attempt at asking..........
Aparently, i have a kindle fire 2.
its not been tampered with in terms of operating system etc.
from a restore factory defaults clean up, and then adding a few games from the app store, the kindle stuck on boot
the screen flashes a static logo twice then goes onto an animated logo...... and stays there!
ive got a factory cable - and can get it to go to fast boot screen - just by plugging this cable into the fire [doesnt even need to be plugged into pc end!]
when factory cable is used, it is recognised by pc as "Otter2-prod-04"
Ive tried some of the programs designed for the mk1 but [aparently luckily] have failed to get any kind of communication between pc and kindle
despite trying several drivers - this is as far as ive got - anyone out there willing to lend a hand before i throw it in the bin?
cheers in advance

Well... When it gets stuck on the boot logo, that means that a system file is corrupt, or you tampered with the autoexecute file and put an invalid command in it and it's stuck trying to execute that command. My recommendation is to reflash the system partition and erase the data, cache, and dalvik partitions (basically the same thing as doing a factory reset from Fire OS) if you have a custom recovery, this process would be a lot easier to do, but if you don't, boot your device to fastboot and type in the following commands:
fastboot -i 0x1949 flash system <the system img that you downloaded> *This will take 5-10 minutes to complete*
fastboot -i 0x1949 wipe data
fastboot -i 0x1949 wipe cache
fastboot -i 0x1949 wipe dalvik
fastboot -i 0x1949 reboot *remove the factory cable as soon as you press enter on your keyboard, or else it will just boot to fastboot again. If it does, just plug your factory cable in again and try rebooting again*
You should see the device boot successfully into the "Welcome to Kindle Fire" screen where it asks for your language.
NOTE: If you see a red screen after you reboot (RSOD), then the system img you flashed isn't the latest version. Try to look for an img with the latest version.
Hope this helped,

[How To] Fix Stock Kindle Fire 2 Bootloop

A few months ago I tried to root/ gapps a KF2 for a friend, and after a freak OTA update the horrible thing kept getting stuck in a bootloop.
Basically if you powered it on it would get stuck on the Kindle pulsing logo until it restarted itself from scratch and did it all over again. Then on the few times it would get to the standard lock screen it would freeze up there and restart itself anyway.
Every now and then it would boot in and work fine though.
What I eventually did to get it working:
1.) Get a factory cable (they don't cost too much off ebay).
2.) Using fastboot mode clear the data and cache partition:
Code:
fastboot -i 0x1949 erase cache
fastboot -i 0x1949 erase userdata
20 seconds later the device worked perfectly and hasn't bootlooped since.
It might also be possible to do this by a.) installing TWRP and erasing the cache/ data from there, or b.) booting into the bootloader from a rooted system. I don't want to test this though because at this point I just want to make this awful thing work properly in stock.
I hope this helps someone else in the same situation. I do remember reading a similar problem on XDA a few months ago when it started giving trouble.

You need to use the fastboot application. You can get it either via the Android Development Kit (just google for it) or just use it from any other source (I know the FlashTool for Sony phones has it along with ADB). Once it is on your PC, open a command prompt window to that folder and run it from there.
Just remember you need the Kindle to be in FB Mode (the screen has a picture of a red and green stoplight on it) and you need fastboot drivers installed for the device (this is a bit tricky for Win8, no problem for Windows 7 though).

Please make sure that you have a Kindle Fire 2 (or at least something in the second generation Fire range). It might help if you take a picture of the device in fastboot mode and post it here.
Also did you boot the kindle into fastboot mode using a factory cable, or using a command from Android itself (it would have involved adb shell).

Trying to do any work on a Kindle without a cable is a total pain. If you own the device just pay the few dollars to get one and make your life easier.
If you cannot get into ADB with full root, or a 3rd party recovery that was already installed you will need the cable to fix things.

What is the process to flash back to stock on a KFHD8?

Title says it all. I have the .img backups. Gotta send it in for a warranty replacement.
Thanks in advance for any help.
I've never done this but verygreen's thread http://forum.xda-developers.com/showthread.php?t=2017562 has instruction at the bottom.
Where it says:
Code:
fastboot flash boot /path/to/mmcblk0p10 -i 0x1949
What specifically needs to replace the /path/to portion? It says to remember where I put the .img files (I keep all of that in a specific desktop folder).
The path of the images is C:\Users\My Name\Desktop\Kindle Fire Resources\New Backup Images\stock-recovery (for instance)

Start with the Kindle off.
Open a cmd window like when you did the 2nd-bootloader install. Enter:
cd "C:\Users\Your Name\Desktop\Kindle Fire Resources\New Backup Images\stock-recovery"
fastboot -i 0x1949 flash recovery stock-recovery.img
(here your PC will wait for you to connect your Kindle via USB. Once it powers on, the fastboot command will automatically place the Kindle in fastboot mode and begin to run.)
(once that is done enter the next command)
fastboot -i 0x1949 flash boot stock-boot.img
(and finally)
fastboot -i 0x1949 flash system stock-system.img
(this command will take a long time unlike the first 2 which complete fairly quickly. next up, we need to clear out your user data and cache -- including sdcard. enter: )
fastboot -i 0x1949 format data
(then)
fastboot -i 0x1949 format cache
(and last)
fastboot -i 0x1949 reboot
If all is well this will reboot the Kindle into a brand new Amazon start up screen.
NOTE: I'll have to double check the format commands as I'm typing this from memory.

Ah, I didn't realize it was as simple as changing the directory and running the commands, I thought I'd have to reference the specific location. Thanks so much for your help.
For some reason it's only going into fastboot for about three seconds before turning off. Ever seen that before?
EDIT: It's also doing this when I attempt to boot it up or plug it into the charger. Has a good charge.
EDIT2: Later, plugging it in leaves it sitting on the Kindle Fire screen.
This is after flashing the boot.img failed. Am I stuck?
This is odd behavior. Normally it will sit on the fastboot screen for quite a while.
Do that screen showing "fastboot" actually come up? Or does it show the Yellow logo and then stop?
Not really stuck. All of the commands you're using are for fastboot mode which doesn't require a full Android OS.
Just need fastboot mode to work.
EDIT: What are the sizes on your stock-*.img backup files?

Recovery: 8,192
Boot: 8,192
System: 907,264
Recovery and boot flashed, but then it randomly turned off. I unplugged the Kindle (which had already given the Windows dismount sound when it turned off). I ran the flash system command, plugged the kindle in when instructed, and it turned off after a couple seconds of flashing it. Now it does that every time you put it in fastboot - display for a couple seconds then go away. I've got it plugged in and sitting on that KF screen for now, hoping maybe it just needed some extra juice or something.
FYI - I actually had to do TWO of these. The LCD cracked on one, and Amazon sent this replacement. The cracked LCD device restored just fine. The only exception were those wipe commands. They didn't work, but it booted into stock recovery and asked me to wipe, and it's good to go. Back in the box and ready to be shipped. This device (replacement for the cracked LCD) has a faulty power button, which I suspect may be part of my issue. Replacement number two arrived less than an hour ago.

My Kindle Fire is very bricked

I used Hashcode's method to install a second bootloader and to install recovery and CM10.1. After I flashed CM10.1 like normal, I didn't like it, as the screen resolution was way out of whack. So, I restore using fastboot the stock .img backups that I created prior to rooting.
Well, now my Kindle gets stuck on the Kindle splash screen, and no matter what I do to flash stock back onto it, every time it reboots, it has the same problem. I have tried the KFHD restore tool (none of the commands work), KFFirstAide (the same problem as KFHD restore), I even tried doing the rooting process again, with the same results. I cannot get this cursed device to boot into stock OS, and I have burned out on trying to fix it. I've had this thing for one day.... :crying:

Which splash to you become stuck at? White and orange logo or white and blue? If you get stuck at the white and orange it is a stack installation failure. If you get stuck at the white and blue logo the system is likely broken. Can you access recovery? Get it into fastboot and try
Code:
fastboot -i 0x1949 erase cache
Code:
fastboot -i 0x1949 erase userdata
at the userdata part it could hang just let it sit for ten minutes or so. Then
Code:
fastboot -i 0x1949 reboot
side note this will wipe your sdcard so all backups and rom files will be gone. So best you transfer all you wish to keep to your pc.

With a lot of persistence, I finally restored it. I had to use KFFA. It was ver likely that it was a stack failure, as when I was using Hashcode's method to root, I never pushed a new stack (because adb wasn't working).
But all is good now, I fixed it! :victory:
After the fact
I suppose it's not much a help now but using fastboot has helped me a lot with my kindle. I've locked it up several times to the point I thought it was broken. Usually it seems if you can turn it on and you see anything, you still can fix it.

[Q] Kindle Fire Unbrick Help

Hello all! I currently need help unbricking my Kindle Fire 2nd Gen. My kindle is stuck in the "Kindle is Upgrading" screen after rooting it and accidentally messing up the default launcher. I'm trying to factory reset it, but I can't figure out how. Since my Kindle is in this state of upgrading, my computer won't recognize it, even with EVERY driver that you're supposed to install installed (And yes, I've tried uninstalling every driver and reinstalling them all). I bought a fastboot cable, but of course I can't really do anything with it because I can't install a recovery or even get to the android recovery without it being recognized on my computer. When I plug in my Fastboot cable, it just says "Fastboot" and has a red light and a blinking green light. Is there any way to externally reset it? I tried opening it up and finding a little pin sized hole to reset it, but mine didn't have it like their's did. I really need help, my family is poor and I use this for many things and we can't replace it. Please help!
Hello again.
In your last forum thread, you stated that you got the ADB/fastboot drivers to work on your computer. If that is true, download the latest firmware from amazon here: http://www.amazon.com/gp/help/customer/display.html?nodeId=201016370
Move that to your platform-tools folder. Press shift+right-click and click open command window here then boot your kindle to fastboot mode and type fastboot -i 0x1949 flash system <insert update file name here>.bin and press enter. It should now reinstall Fire OS 10.5.1 to your kindle, but you aren't done just yet...Unfortunately, I can't remember the fastboot command to wipe the dalvik cache (someone please reply with the command, you will be thanked!). After you wipe the dalvik cache, type fastboot -i 0x1949 reboot and unplug the fastboot cable right when your kindle's screen goes black. It should now take several minutes to boot to Fire OS, so be patient! If it has been 10 minutes and your kindle hasn't booted, try to flash the OS again but don't wipe the dalvik cache (since we already wiped it). If it still doesn't boot, then something has gone horribly wrong with your kindle, I'm afraid, but reply if this happens, as there is one thing we can still do.
Hope this helped,
Nick

[Q] No fastboot/ADB unauthorized/TWRP loop = Bricked?

Hi all,
I apologize in advance, but I was unsure if there was another thread my issue would best be posted. I have a kindle hd 8.9 32gb that is now stuck in a boot loop at the twrp (2.8.3.0) splash screen (after installing the new Candy5 5.1.1 rom). The rom installed fine and ran perfectly the 1st time, but upon the next device restart it entered the recovery loop and never gets past the splash screen. The kindle itself is recognized by my pc while the screen is looping, but adb shows the device as "unauthorized" and of course with the looping issue I am never prompted to enable. With the 8.9 and no ADB, I also am also unable to enter fastboot mode. Any thoughts or suggestions, or am I bricked with the only possibility being a direct e-MMC restoral? *my soldering kung-fu is extremely weak*
Thanks in advance for any answers!
I have the same problem as you. I updated CM to 12.1, perform a factory reset and I got stuck on twrp screen which is blinking...
Possible Solution
I did something similar but with latest CM nightly rom and got stuck in the twrp recovery mode as a continuos loop, but mine was detected with the status "recovery" via adb;
Check if your adb /fastboot drivers are correctly installed and your not pluggin your kindle to a usb 3 port, then try this:
adb reboot bootloader
It will order the kindle to reboot in fastboot, after that you can just reflash the kindle to its original state with the fastboot commands from your backup.
Dont forget to erase the userdata, cache and all that stuff, you can do it with kindle firstaide
After that just redo all the process of rooting and install a Custom Rom.
Note: I got stucked on a loop of the kindle fire logo, cuz i didnt erase the userdata, but I was able to enter fastboot after the restore, thats why i suggest you delete the cache and other stuff
EDIT: Nevermind. Managed to resolve the issue by booting into fastboot mode, erasing cache and userdata using SR Tool from the KFHD_SRTv1.3.5 and then sideloading the ROM and GAPPS. I lost everything but it means i do not have to buy another KFHD.
Really grown attached to it, especially when the guys at Cyanogenmod keep on releasing updated OS's every year or so, making my tablet feel new every time.
Good work fellers.
I have a Kindle Fire HD with the CM12.1 ROM installed. After installing a nightly i did a factory reset from within the OS and it is stuck in a bootloop occasionally flashing on the teamwin splash screen.
Have i bricked my system or is there a solution.
I posted here because it appears that the op and myself have the same issue.
I tried ADB method but when i use the command "adb device" it shows as unauthorized so it will not allow me to run the adb shell or reboot command.
Any solutions will be much appreciated.
Hi to all
I have the same problem with twrp blinking after a factory reset on cm 12.1 ... I tried adb or fastboot commands (with KFHD_SRT_v2.1 or latest android sdk tools) but I cannot see my device. Consider that I installed adb drivers on a win 8.1 pc with 2.0 and 3.0 usb ports and I am using the standard cable included in the kindle fire hd 8.9 package.
Where I am wrong? A fastboot cable can solve the problem? Sorry for this question but I read many threads and there are different opinions about that...
Thanks in advance for any help.

When it's in the TWRP bootloop, the device should be in adb mode, so you can flash recovery, erase cache, etc..
I'd start off with a "adb erase cache", and that should get you past the TWRP bootloop.

I'm in this same situation... BUT, I finally got into TWRP and was starting to restore the ROM, but then my battery died... while i was in TWRP recovery.
Now my device won't power on (won't get to the Kindle Fire boot logo). I can't adb or fastboot, since the device won't power on, even when I plug it into the computer. I've tried charging it overnight, hoping that would help.
Nothing.
Do any of you Android gods (@Hashcode) have anything else I can try? Anything in the Android SDK that might help and at least allow the device to accept a charge?
Thanks!
Same problem
I'm in the same situation as the OP. Unfortunately, my device is unauthorized in ADB and since I'm stuck in the TWRP loop, there's not much else I can do. I wondered if it was perhaps the drivers causing the issue, so I fuddled around uninstalling and reinstalling to no avail. One thing to note is I'm using Windows 10, not sure if that could be causing any issues.

when in fastboot mode, hook the kindle up to a PC with a terminal/command prompt (also make sure the kindle drivers are installed if you're running Windows) and enter fastboot -i 0x1949 oem idme bootmode 4000. you should see successful text on both the kindle and your terminal after running that command. if that's true, just do fastboot -I 0x1949 reboot afterwards to reboot the kindle.

No, that's a separate issue. What I would suggest right now is for you to download the bootloader, freedom-boot, and TWRP 2.8.7.0 from Hashcode's thread, reboot to the bootloader from CM recovery, and flash the files as directed to in step 5. However, don't power off the kindle - it's already in fastboot mode, so there's no need to turn it off and tell it to reboot into the bootloader. Also, ignore the post warning about flashing the freedom-boot image - we're only using it temporarily.
Once you have the files flashed, reboot into recovery. If you're in TWRP, go ahead and flash CM or another ROM. Just avoid booting into system until you do so.

Hi Monster 1612! Thank you very much for helping me out. Please bare with me b/c I am a newbee. Should I download File no.2 & 3 from Step 2 or more. Can you explain a little more about "reboot to the bootloader from CM recovery" . If I do that it takes my device to fastboot mode. What is flash the files as directed to in step 5. How to flash the files in flashboot mode". Is there a link about this? Are you talking about codes in the box in Hashcode's thread? I really appreciate your help.
The files and instructions should be located in this thread.
As for booting into fastboot mode on the kindle, this should be easy - in its current state, it just boots into Cyanogen Recovery, right? Anyway, you just need to choose option 5 in that recovery menu to enter fastboot mode.

I downloaded the bootloader, freedom-boot, and TWRP 2.8.7.0 from Hashcode's thread, reboot to the bootloader from CM recovery, and flashed the files as directed to in step 5 from Hashcode link.. Didn't power off the kindleas at it was already in fastboot mode as you said. Once I had the files flashed, rebooted into recovery. Wow, it rebooted into TRWP recovery mode. with 8 buttons (reboot,advance,mount,setting,restore backup,isnstall, wipe). I was so happy because of your help. Then I did the stupid thing. I rebooted probably into the system. Now My device is stuck in Kindle fire Yellow/white logo. Now ADB command works but adb devices dont bring anything ( waiting for devices). The driver is installed but my PC does not see it device manager. I lost fastboot mode too. I was so close sir because your help. I remember you telling me to flash into a ROM and not boot into system.
That makes me a real noob. Now please help me if you can. What is next? Is thre still a hope?

The bootloader should still be responsive regardless of what's been flashed onto the kindle. Go ahead and completely turn off the kindle (hold the power button down for 10 seconds till the screen turns off), and then open a terminal on your PC. Type in fastboot -i 0x1949 getvar product , and plug in the kindle when you see <waiting for device>. After a few seconds, the kindle should be in fastboot, and the prompt should have outputted something like "jem-pvt-prod-04". Now repeat that flashing process again, and type fastboot -i 0x1949 reboot when done. Press and hold the recovery key (the one closest to the camera) until you're in TWRP, then flash CM or another chosen ROM from TWRP.
Happy to help!

My friend , you are becoming a saviour. Have you got any donate button for support? I would like to contribute. This time I am not going to rush. Want to make sure I undestand everything. What is [/I] before / after fastboot -i 0x1949 reboot and fastboot -i 0x1949 getvar . I hope its not any part of command. BTW, I dont see any key near the camera ( recovery Key?). I have kindle fire HD 8.9. This has power key and up and down volume key.

So far, I don't have a donate button - I'm worried about its legality, cause I'm not 18 for at least another year.
Anyway, the button we're talking about is volume up. It's the one closest to the camera, and the boot partition's programmed to boot into recovery when this button is pressed and held during initial boot (I.e.: when the Kindle Fire logo appears and changes from orange to blue). The fastboot flashing process I described above goes like this:
1) Power the kindle off completely, type fastboot -i 0x1949 getvar product, plug in kindle when prompted.
2) Kindle should boot into fastboot, and "jem-pvt-prod-04" or similar text will appear.
3) Flash TWRP, freedom-boot, and the 8.1.4 bootloader as you did before.
4) Type fastboot -i 0x1949 reboot when you're done flashing, then immediately press and hold volume up as soon as you see the kindle fire logo. Keep holding until you're in TWRP.
5) Flash a ROM, as well as gapps if desired.
6) Profit
Hopefully, this clears up any confusion.

Hi Moster 1612!
I followed step by step evrything went by the book in fastboot mode ( see below). You are great. However, I cant understand for some reason, it did not boot into TWRP recovery and went back to Kindle fire logo. I did press the volume up key As soson as KF yellow logo came in but it stayed yellow. . I can turn it off by pressing for 10 secs. Now what my young friend?
