[Q] Kindle Fire Boot loop

Okay, I have a kindle fire and ive tried all the utilitys to fix this but none of them work.
The kindle boots up, and says the following processes stopped unexpectedly
com.android.providers.calender
and android.process.acore and then the device shuts off and loops over again
Its on the stock rom and i have no idea how to fix it
thanks in advanced

Do you have root, bootloader, and recovery? It seems your calendar or contacts are corrupted and require deleting some files, but unless you stop the reboot you won't be able to do that. I would recommend using recovery to wipe the cache and factory reset.
BTW, does the stock ROM include Google Calendar?

Its completely stock, I can't get the Kindle fire utility to flash the boot loader because it reboots itself and it keeps saying "waiting for the device". I've installed the drivers and nothing is working. No root.

Unfortunately to fix this problem you'll need access to fastboot to install custom recovery. You'll be able to revert back to stock afterwards but you'll lose some data in the process.
The easiest way to do this is with the Kindle Fire Utility but you run the risk of running into some trouble (but not much). It's unnecessary and potentially dangerous to install a bootloader if you plan to revert back to stock so don't even try it.
You absolutely have to make sure your drivers are in order to get past the "waiting for device" problem. Make sure you've read and understand the following tutorial on device drivers:
http://forum.xda-developers.com/showpost.php?p=23747671&postcount=2
Once you have recovery installed you'll be able to reinstall the stock 6.3.1 update which will fix your original problem and revert your device to a pure stock state (no root, no recovery, etc.)

Okay, I've double checked the drivers for the device, can you post a thread with exactly how I use fast boot and install a custom recovery? And I plan to revert to stock and then use install a custom recovery image and then cyanogenmod 7 over that. Does the device have to be powered off or on to access fast boot and install a custom recovery image? The issue I have is the device powers on and stays on for only about 15 seconds, and then it dies on my again. Also, thanks for the quick response

If your drivers are in order you can use KFU to install custom recovery as it does everything for you.
If you want to do it manually you need to read the following posts:

Just remember to skip the bootloader.
[Edit:] The manual method also requires working drivers.

Thanks for this suggestion. :good::good: My kindle went into a boot loop after I hid the SU account with Voodoo OTA Rootkeeper. It took several tries to get it to go into recovery, but managed to get in. Wiping the main cache fixed the boot loop for me.

Flashed cm10.1, stuck on boot screen

I flashed cm10.1 and latest gapps after rooting with kfu and going to twrp to flash zips. After rebooting the kindle stays on the rotating CM splash screen. Is there anything I can do to revive my kindle. I can't get my PC to recognize it and I can't get to recovery. I have the correct drivers installed bc i used the kfu only a few hours ago. Any help would be greatly appreciated

When you plug in the usb to the computer do you get any change in windows device manager? like an unrecognized kindle fire (yellow triangle) under usb or similar?

Looks like you might need to reflash. Don't forget to do a wipe/factory reset...

That's a strange problem. Have you tried to reinstall the drivers or use a different PC? If it can get into the boot animation, you should theoretically be able to get into recovery/TWRP... Sounds like a bad flash may have happened so try a newer/older build. I hope it goes ok...

Use this to replace the the one in kfu driver folder http://db.tt/vXXeuL10 and rerun the driver bat, that will get adb going again. Try reboot recovery to enter recovery or use kfu to set your bootmode to recovery. Bootloader? fff will take you to recovery as well.

I replaced the file and still shows ADB status as offline and boot status as unknown. The computer makes the noise that a device is connected once the kindle reaches the CM screen but the that is it, ADB is still offline. Also, the kindle fire logo at start up is no longer blue, it has reverted to the stock orange color.

I have the same problem with CM 10.1 with the splash screen. It loads through FFF 1.4 and gets to the spinning splash screen which appears to be half off the screen and just sticks there. I used the 0102 version of the JB 4.2.1 CM10.1 SGT7 rom by twapriv. When I flashed it using TWRP 2.2.2.1 it said "successful". I try to install the 121212 Gapps zip and it wouldn't work, saying unable to unzip. However, after a reboot the splash screen does what I just mentioned.
It appears we aren't the only ones though (http://forum.xda-developers.com/showthread.php?t=2051331&page=24) according to stewtang's post. I guess I'll retry to flash an older version and see if that works. Anyone have this problem and found a fix for it?

I have always been able to get into recovery. However, I did find that my /system/bin/sh file and all other system files are completely missing. I have yet to fix this, as this could be some of my problems. I don't know I'm still a noob at this. I have reflashed TWRP 2.2.2.1 while in fastboot mode using a factory cable. I just bought one for $6 on ebay from a US seller. Using this cable I find that the KFU works more like it should. It actually tells what boot mode status is currently instead of just saying unknown.
I know I did something wrong or out of order when I tried to root my KF because it is very difficult to do an ADB PUSH command successfully. It takes a few reboots and then a trial and error until it works right. As for the latest 0102 update for CM10.1 and SGT7, I haven't been able to get passed the cyanogen splash screen.
I would like to know if that update includes all the files necessary to run JB 4.2.1 or is it a completely different OS altogether? Again, uber noob here.

So a question for both of you. Did you do a clean install (wipe everything but SD card)? Also does it hang on the CM screen or does it endlessly reboot? Did either of you have previous ROMs installed?
When I installed CM10.1 on my friend's kf, at first that happened. I don't know what happened, but it took me a couple tries before it worked. Try redownloading the ROM and Gapps, and remember to wipe everything beforehand, and wiping cache before flashing Gapps.

Yes. I performed a clean install and unfortunately I am unable to re-flash anything. When the kindle boots it endlessly stays on the cm splash screen and I can't enter recovery or use the kfu.

So for you, when you turn on from off, possibly from a hard force-restart, what do you see? The original orange kf logo? And it goes straight to the swirling cm logo?

Yes that is what I see, but before I flashed it the kindle fire logo was blue.

I had the same thing happen to me when I flashed my kindle fire demo unit with CM10.1, it turned out to be some sort of an issue with the twrp recovery when I reflashed it with the cotr recovery that the kindle fire utility program also has as a alternate this worked just fine. I did notice that when I tried to use twrp to wipe my unit it didn't seem to fully wipe the unit. doing the same thing under cotr took longer.
The reason I think it was twrp is that no matter what version of CM10.1 I used be it a nightly or the M3 experimental build, it would still just show the distorted logo and never finish booting. this happened even after I wiped the /system and cleared cache and dalvik cache.
After I flashed cotr recovery I did the same thing again using the exact same zip files for CM10.1 and gapps and it worked this time.

I have a similar problem with you guys. My Kindle is showing the orange logo and then continues to the CyanogenMod animation where it loops infinitely. The logo is also off center, half of it is off the screen. I cannot enter the recovery mode in any way. KFU shows it as online but unknown boot status. ADB shows it as offline.
Any suggestions on how to fix it? Will I need a factory cable?

I'm in the same boat, tried soupkit in linux and no dice, windows recognize a device while the CM logo is looping but the kindle drivers or adb drivers do nothing.

In both of your cases, if you don't have FireFireFire installed which will allow you to access recovery with the power button, you need a factory cable. And remember to factory reset next time.

I did, I was going to sell it with CM10, I rebooted, did a factory reset, reinstalled cm.zip and gapps.zip and rebooted....lost firefirefire and stuck on CM logo. If I buy or make the factory cable, will it be easy to "revive"?

[Q] KFHD 8.9 Static Boot + No Access to TWRP

Hi all! I'm hoping I can get some help. I have a Kindle Fire HD 8.9 "Jem". I successfully rooted it the other day, and after switching laptops, finally was able to access fastboot on the computer and get the successful output. I followed the directions from this link:http://forum.xda-developers.com/showthread.php?t=2277105. I got all the way through it successfully to the end of step 3 to reboot into TWRP. However, once I rebooted, I get a constant bootloop on the static Kindle Fire logo. No twrp (I put 2.7.0.0 on there, and checked to revert to 8.1.4, but based on what I have read, I MAY have forgot to check the box to load stack).
I found SRT tool from this link: http://forum.xda-developers.com/showthread.php?t=2011126 and used it to successfully get the Kindle to show fastboot on the screen. However, now I'm at a loss as how to continue. I made backups per the 2ndBL+Twrp thread but I have no idea how to proceed. Any assistance on how to proceed would be greatly appreciated. I'm not very proficient in using the commands, but can follow the directions pretty well (or so I thought lol).
Thanks again for any guidance.

Ok I got it back. I figured out I needed to open up a new command prompt in order to enter the fastboot flash commands and flash my backups on to it that I made following http://forum.xda-developers.com/showthread.php?t=2128175. Now going to try this again and hope to get TWRP and CM working on it this time around.

UPDATE:
Okay, I'm now further than I have ever gotten before. I have successfully installed TWRP version 2.7.0.0, able to access it no problem. I installed CM11; I have tried both CM11 20140702-NIGHTLY-jem and CM11 20140504-SNAPSHOT-M6-jem. Before installing each one, I wiped system, cache and dalvik cache.
However, with each one, this is the problem I'm having. I am stuck at the cynogenmod boot screen (blue alien/android with the arrow circling). I have not been able to get past this. Is there any guidance that you all can offer me to get past this? When I saw that cynogenmod bootscreen pop up, I was so excited and relieved that I got past the blue kindlefire logo this time around, but am again deflated. I know I can boot back to rooted stock from my recovery files so it's not a total loss. I just so want to see it load up as android!!!
Thanks in advance...hope someone sees this. I didn't want to add another topic to the board, so the title doesn't reflect my current issue. So I hope that it'll get some answers. If I should make a new topic, please let me know. As my post count reflects, I am a newbie here. Thanks so much for all the hard work that you all do to help us!

Success!
Just wanted to update!
After wiping cache/dalvik cache/system and then wiping factory reset, and then reinstalling CM11 M6, it finally worked! SO now my kindle hd is now a beautiful full fledged android! I just want to thank all of the people here with all of their knowledge and guides, answers to questions in the threads...I finally figured it out and feel accomplished! LOL.

Maybe you can give me a hand as you've recently gone through this:
tried the 2nd bootloader instructions and the '8.9 Flasher' zip found on these forums, but right now I'm just stuck at the kindle fire logo (not moving). I can get into fast boot, but don't know what to put in there to get me either back to stock, or into CM11.
I (like a fool) didn't make a backup (i used the flasher zip first, and neglected the backup option), so are there stock images out there I can use?

When you restart your tablet do you see the blue KF splash screen? If you can you should be able to sideload a ROM onto TWRP.
If you can't get into TWRP then see this restore tool http://forum.xda-developers.com/showthread.php?t=2011126 you can flash the images manual from the tool if you'd rather not run the bat. Choose option 3 if you do as that includes the recovery as well.

im still in the process of fixing everything, but I was able to move past where I was (stuck on static kindle fire logo) by using fastboot to push the stock boot.img, recovery.img from hashcodes post, and then using the system.img from onemeila's rescue post (also wiping the cache)
im still in the process because my KF did an OTA update (!>@#) while I was pushing other files to it, so I had to start over again.

[Q] Bricked after accidentally flashing older stock firmware

Ok so to start this was my first time roots and putting a custom os on an android device. It's a first gen kindle fire the firmware originally on it was 6.3.3. I rooted it using safe root with success. I then proceeded to install TWRP and that worked with out an issue. I basically followed lthis tutorial. I then booted into TWRP and cleared the cache then did a factory reset. I then install the newest version of CM 11 without issue then proceeded to install gaaps for it but it failed I figured it wouldn't matter (dumb thing to think). Then i rebooted it got stuck at the boot logo so i figured i messed up a step so I figured I'd just start from scratch just to be safe. I went back into TWRP and cleared all the caches and did a factory reset and installed the os from amazons website which i thought was the same firmware as before (6.3.3) but I later found out it was 6.2.1 and rebooted and got stuck at the boot logo again but this time there was no TWRP to boot into which is where I am stuck now. Windows picks it up as kindle in the device manager adb can pick it up too. I figured I'd try rooting it again all the commands it does fails because /system/bin/sh doesn't exist. Then it reboots and says something has deleted su looking for backup copy then says the back up is gone too and it can't recover. I then tried putting it into fastboot mode again with the commands and no luck it says /system/bin/sh doesn't exist so I can't do that. Im stumped now couldn't find anything through googling and searching the forums. Is my kindle bricked?

[Q] Please help. Bricked/boot loop

HELP: I have CWM 6.0.5.1.4a and installed the latest rooted rom. Now I have a bricked device in boot loop. I am able to get into CWM with the ALT+i+prt scrn method.
I have tried installing varoius roms but my device does the same every time. It is just stuck in the color Fire TV logo.
Since I don’t have SU from CWM I cannot get ADB to upgrade to kernel boot menu or downgrade to stock firmware.
What should I do? Any help greatly appreciated!
I also tried the factory reset from CWM but with no result…

Seems you followed part of the guide but did you take all precautions? You need boot menu and unlocked bootloader for that fw. If you have these and confirmed they work, plus you checked mdsums...I can't imagine why it's in bootloop.

What is that method exactly?

Alright, got a question, tried to find an answer everywhere.
Went to update to the newest version through CWM (51.1.5.0_515030720). Forgot to re-install Boot Menu, am now in a brick/bootloop. Despite what I've read, no amount of wiping the data/cache/dalvik cache gives me back the option to simply "reboot." In addition, all the guides tell me that I need to downgrade by installing 51.1.4.0_514006420. That's all well and good, but I have no way to get 51.1.4.0_514006420 onto my Fire TV to install it. Sideloading doesn't work, as ADB isn't functioning properly through CWM. Fastboot doesn't let me install roms or push files on.
Can someone please help me figure out what to do next? I can get to recovery, I have a keyboard, and I don't know how to get this older rom onto the Fire TV.
