[Q] [SOS] 7“Kindle Fire HD always reboot system!!! - 7" Kindle Fire HD Q&A, Help & Troubleshooting

2012-12-14 update more infromation:
We now find, if we use the KFTT, such as play game, watch movies, the KFTT wouldn't reboot anymore during the use time.
But, if don't use, it will reboot again and again.
-------------------------------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------------------------------
This is my friend's 7'Kindle Fire HD(KFTT) issue. ----System auto reboot !!!!
Coz, his English isn't well... So, I'm be here send the SOS...
Who can help him???
The situations are:
1.He bought KFTT on September. The first time the system reboot itself was 5 days after he used KFTT. No Root, No Unlock. JUST REBOOT!!!
2. At the beginning, it would reboot 2~3 times every day. Then, increase to 4~5 times per day. After final reboot, it could be used normally. What's more, the KFTT would be shut down when he went to sleep.
3.When the onemeila‘s System Recovery Tool(SRTool) update to V1.2 (http://forum.xda-developers.com/showthread.php?t=1951254) , he try to use this tool to recovery his system. HOWEVER, when he restore 7.2.1 image, KFTT can't log in the system. When he restore 7.1.5 image, KFTT can log in the system, but can't unlock, whatever he swipe. anything. SO, KFTT is brick!!!
4.Finally, we use fastboot to flash the boot.img\recovery.img etc. Then, the KFTT can log in the system and can unlock. BUT, the KFTT becomes REBOOT ALWAYS after 1 minutes.
I doubt whether it is the system issue or the hardware issue!
Does anyone face this issue?
Does anyone can solve it?
SOS!!!!

no one can help me????

It sounds like you got a defective device. If nothing was done to the device and it was rebooting like that, some is really wrong. So I don't think there is anything your gonna be able to do to fix this issue. I would wipe the device and call amazon about replacing it under warranty. Amazon has great customer service.

ok...
maybe it's the only way.
onemeila, thank you!
I like your tools!

I'm not sure really how to help, but if you can describe the last thing you were doing prior that will help people diagnose it. Were you rooted? Or trying to root? Did you try to modify any system files?
I have the same problem. I was rooted. I was trying to copy the vendor apk into system/ app folder. I think I accidently made copy of app folder, it said app copy then froze. I clicked system restore. did nothing.
Are you able to reach the system with adb shell at all? or not? If not, I think you are stuck sending it back to Amazon for repair/replacement. If you can, you should be able to use the same method you used to root to get /system RW again, and try to fix it up.
I don't know how to use ADB. I used the one click root method. My computer isn't recognizing the device when plugged in. Is there a step by step guide on how to fix it or will it be possible in the future?
If its not recognized, then its unlikely that adb will work. If I had a bricked device though...I would start reading and trying to get that working. If you really don't feel confident in messing around and trying to fix it, call Amazon and ask them to send you a new one.

what do you do so that KFTT state in bootloop?
can you take screenshot? or take a picture?
I am having the same problem.
any luck fixing it?
Hi, I am in the same situation. Here in Spain we have the KFHD since 4 days ago.
I rooted it correctly via ADB. I installed google play and installed several app's apparently without difficulties. The issue came after putting the Go luncher HD apk on system\app. After that I rebooted the device and appeared the two luncher options. So everything ok. I was moving around my new luncher and everything was ok, but suddenly the device rebooted and I had the same issue here explained. Bootloop and no factory default possible. Of course just rebooting didn't solve it. I have to say that the last thing I was doing before the sudden reboot was modifying permissions from SU. Maybe it's related, so don't touch anything from there. ADB was not working any more so very few things to try...
Amazon accepted a replacement (I just said what happened but not why) and now I'm waiting a new one.
Hope this can help.
Regards,
If you're willing to do a little work, you can try this recovery method: http://forum.xda-developers.com/showthread.php?t=1951254. Personally, I would just send in the device to be replaced, and not tell them the exact circumstances of how the problem happened. Amazon's generally pretty good about returns and replacements while you're still within warranty.
I shouldn't have restored factory defaults
I am in the same issue
The main mistake I made was selecting "Reset to Factory Defaults"
This automatically turns off the debug mode and with it stopped any communication between my PC and the Kindle Fire HD 7". Even the Factory cable I bought for £3.19 didn't help. The driver shows like it is installed correctly and my Kindle shows Fastboot on the screen when connected, but there is no communication.
I only got it for Christmas and I've goosed it. I am now hoping Amazon will be sympathetic and believe that it just started looping itself without me modding it.
When you reach the fastboot screen unplug factory cable and insert the usb that came with it. Then check your drivers to make sure they are Installed properly. Then use system Img restore tool to restore, follow directions exactly

Hello All! I was messing around with App Quarantine and ended up bricking my KFHD (not sure what I did because I was still messing around with it.) My KFHD is rooted but I didn't install TWRP or any type of recovery program. Is there any way for me to unbrick this or am I stuck with a fancy paper weight?

Lord NO! Any Kindle with the letters HD after Fire have nothing in common. Anything run to access the system or modify it will guarantee a permanent brick with NO WAY OUT.

Technically, the factory cable will still work, even if there are ways to know that you shouldn't do some things (like number 4 in the thread in my signature).

It was sort of a failed attempt, so what the heck.

[Q] If you can fix this brick. . .

Alright from the get go. I am running 10.3.1. I rooted using a tutorial from this site, it was rather easy. It only took me like 25 minutes and then to add the Play store, another 25. I had it running perfectly fine with GO launcher and it was the way i liked it till I saw NEXT launcher and I wanted that instead. I had GO still running and being a noob I thought if I installed NEXT launcher that it would be able to be set by default when I was asked and that would be it. From what I can tell they were fighting for the kindle's affection and it was at a constant refresh directly after the install. I then soft reset it and I'm stuck at a kindle fire screen. The animation is very fast, with no delay between ending and beginning again. I tried today using the KFU to no avail. I also tried to reinstall the drivers, nada. my computer in device manager does read it, "other devices" Kindle" Uppercase "K". I've uninstalled and reinstalled. I cannot get the SDK to work on my computer. Even with the correct environment setup, nothing. I've viewed plenty of other fixes, none help my situation, not because I don't think they do, but because I've tried. When I KFU I get a Waiting for Device, nothing further happens (40 minute waiting period). I tried to Recovery boot and I tried to push TWRP, nothing. I'm at a loss. To be clear idk what fastboot is and I don't know how to "code" anything so anything help in detail, would be awesome, you guy are a great community and I wouldn't dream going any where else for expertise. Thanks for any help. Btw AMA and I'll try and best accommodate so I can fix this

http://forum.xda-developers.com/forumdisplay.php?f=2097. You said your device runs 10.3.1. The 7" KFHD runs 7.3.1 and the 8.9" runs 8.3.1, only the KF2 runs 10.3.1.

[Q] Can´t solve bootloop after read various threads

Hello,
I ´m waiting an answer to my problem posted here http://forum.xda-developers.com/showthread.php?p=42053547#post42053547, but I have another question to post here.
How can I fix the bootloop if I have the ADB disable (and I think the third party is disable to)? My KFHD is version 7.4.1.
I will thanks if somebody could give me some helpful idea!
Gustavo.
Hey Elgari, just saw your problem and actually answered you in two different places Basically you can't use adb. You can only use adb when you're in recovery or when booted. You'll have to go with fast boot. Can you get into fastboot or do you have a factory cable? If you can get to fast boot then you can use the kindle SRT tool from the development thread.

Thank you very much Droidlt! I´ve read your answers and is clear: need a factory cable to go with fastboot. As device manager recognizes the KFHD as adb android composite ADB interface, I had hopes of not requiring the factoy cable. Had also read some posts suggesting that it was not necessary, but now I understand I need one!! Thanks again. I don´t have a factory cable but will try to buy or make one.
I supose the SRT is the threat post by Onemeila, isn´t?
I love my KFHD and would like to understand why! This setback makes me love her even more. Would know If it was something I made wrong or if it was and accident.
Finally I must apologize for writing my problem in more than one place, but I was really frustrated!!
Thanks once again.
No prob Yep just a factory cable. Just make sure your kindle is off, plug the factory cable into the computer and then your kindle. It will automatically boot up your kindle into fastboot mode. Then swap out the factory cable for a regular usb cable and run onmeila's SRTool, doesn't really matter which version you download, you can root them all. Flash whatever version you downloaded and you have a new kindle again :thumbup:

Hello Droidlt!
Well, I made a factory cable and put the kindle in Fastboot. I run option 1 of SRT and seems do the work: it begin with "sending systems, then Okay, after "writing systems, then okay and after it said finished, Welcome Back. But nothing changes!
I tried with option 3 to, and I tried changid the SRT folder to Plattform tools as I read on Onmelia´s threats. But same results.
My device manager recongnize my KIndle as Android ADB interface. I used the code adb shell su -c "reboot bootloader" and give me the results: device not found.
I make something wrong but I don´t figure what is it!!??
Thanks from now for any suggestion!
Hey Elgari, so did it boot up or no. What exactly did you see on the screen after you ran the SRTool?
Edit: Ahhh, I see what you did. You only need to use that command if the fast boot cable didn't work. Your fast boot cable did get you into fastboot though. Just unplug your kindle and reboot it. I think you're good.

The screen of the kindle never changes: always remains on Fastboot (in orange) with kindle fire bellow with small letters. In the PC I saw the menu first and then the others steps I´ve mentioned. Nothing else. Let me know if you need more information to try to help me.
It's late here but I'll be a few more minutes.

OK, go ahead and turn your kindle off by holding down the power button for 20 seconds, hit the power button again like you would normally then. It should boot up.

I am exactly having the same issue, currently on Fastboot Screen and turned the kindle off by holding down the power button as per your instruction. After reboot it goes back to kindle Fire HD logo screen.
Pls advise.

Thank you Droidlt! I did that and it returns to normal boot but it continues locked in boot screen: normal Kindle Fire Logo no matter how long I leave it turned on. I left all night charging plugged into the wall. I tried last night another thing. I run step 3 of Kindle Fire First Aide. Same things, it run all ok but no fix the problem.
Other comment is that when running step 5 of SRT my kindle screen changes to normal boot and in the pc the screen back to SRT menu doing nothing more.
I will ty now tu run again step 1 of SRT and I will keep you advised
EDIT 1
I run SRT (step 3 instead 1 because I think is better). Same results: stays in the initial screen with the logo of kindle fire with a kind of light passing through. I run step 5 to chek fastboot status and same results: the kindle changes from fastboot to normal but still stay in the initial sreen as described. I run step 6 and in the PC the screen said waiting for devices while kindle is in the screen described. I left 10 minutes and nothing changes. Now I turn off the kindle holding down power button for 20 seconds, wait 5 seconds and hit the power button again: same results initial screen with kindle fire logo, etc.
In my desperation being the kindle in this initial screen I just ran Kindle Fire First Aide to check ADB status. The results was I have ADB comunication !!! Its says "device attached D025A0A024421317" "It looks like ADB is enabled". But kindle is in the same screen . . .
EDIT 2
FIXED!!!!!!!!! Or I think its starting to be fixed!! Y run various steps of KFFA and finallly with option 25 (Restore from Kindle backup folder) and disabling OTA its seems to be fixed. I said its seems because its a backup from my previous status which was who has the problem of turn off by itself.
What do you think? I leave it like that and see what happens or I do anything extra?
Thank you again!!!

So you're booting now? I was thinking back on what I suggested earlier, and I actually should have suggested the 7.2.1 SRT version. I remembered that there are no options in the 7.2.1 version, it's older but it's all automatic, and therefore easier. All is good now though?

In my last post I was editing and adding what was done to you had the whole "history"!
Now the kindle works fine but I have still plugged with usb to the pc. The problem I had before and was he origin of all the subsequent problems was that when unplugged and surfing internet she power off. Now I left it in version 7.3.1 and not going to upgrade to 7.4.0 in case that was the problem. In a little while I will unplug and see if it goes well.
I used SRT version 1.3.5.
We will see what happend. Thanks again!!

Yes, thank you!! I don´t know now if I´ ve root. I have super user but no have root checker. All previous times I root with KFFA . You suggest try something else if I need to re-root?
I have all my old apps backuped with Titanium, gradually I will recovering them. The others are in Amazon Cloud.
My fear is that one of those applications might be causing the original problem (if that can happen). Because I keep wondering if installing PPP Widget and plug my 3G modem could be the cause of the disaster!!

I saw you mention PPP before, I had not heard of that so I just looked it up on the play store and now I get it. That could possibly be your problem, not certain but possible. Amazon modified stock android to such an extent that what may work on almost all other android devices may not work on the kindle. I would suggest to do everything else first: get your kindle exactly how you want it and then do a nandroid backup, and then if you still want PPP, then try it. Communications always seem to be kind of a sensitive issue with any smart device, so you just need to be really careful when you want to make modifications to the stock abilities of that device. So, like I said, I would just get your kindle where you want it, I'm assuming rooted, custom rom, etc., back it up and then maybe try PPP.
---------- Post added at 11:24 AM ---------- Previous post was at 11:16 AM ----------
Oh and I would just suggest that you check to see if you have root first before running any tools. That would be the place to start. I always use this app https://play.google.com/store/apps/...tcheck&feature=nav_result#?t=W251bGwsMSwyLDNd It quickly and painlessly checks for root. As far as tools go, I would just say to use whatever is comfortable and familiar to you. If that tool worked good for you before then just keep using it. If you could just run the app I linked you to and then let me know if you have root or not, then we can go form there. Glad your kindle's alive again
Edit: just read your post again, if you have superuser, then you have root
Edit 2: I'm writing alot here, but oh well Do you have second bootloader + TWRP installed? That would actually be your next step. You can do that by following the instructions here http://forum.xda-developers.com/showthread.php?t=2128848 Once that's done then you can download any rom you want and go into recovery and flash. If you have an amazon prime account or like the amazon reading app that came with the kindle, I would suggest Kinology. If you don't really care about either of those things, then you can go with CM or one of the variants, they're all really pretty good. Anything else, just let me know

He makes good quality and easy to understand guides and it goes through rooting, google play, flashing and more.
I would highly recommend this guide. Also, try flashing Hashcode's cm10 JB rom it 100% working. The link is in the guide.
Happy Flashing

There's a couple ways to skin this, you could either do like CVanB said or you can also go with Hashcode's method here http://forum.xda-developers.com/showthread.php?t=2128848 I used the Hashcode thread and it worked for me and CVanB used seokun's and it worked for him. I would say you could go either route really. If you go the Hashcode route, after you get that done then you just install a rom and they have gapps included, no need to install seperately :good:

[Q] KFHD (2012) rooted?

Hi Everyone:
I am attempting to root and install cm11 on my son's KFHD. I am a bit of a noob, but I have successfully rooted my nook color in the past and read MANY threads on how to root, but I'm kind of at a loss.
The problem is that I followed the thread on how to root and I had a bunch of trouble. I finally was able to get through the steps, but the command box closed before the KFHD rebooted successfully. In an attempt to "fix" it, I restored the device to factory settings. It seems to be working just fine with stock os, but there is a superuser app which has requested access to apps.
I downloaded an app from Mobile1 to check that there is root access and the app indicates that I do indeed have root access. Should I go ahead and try to install a rom?
I would like to root it because my son is using it for school and is having a hard time adjusting to the stock os. (Which I hate, too).
Thank you so much!!!!
-NDH
1. Super User is the app that lets apps have access to root. (easy way of understanding it)
2. You need to Install Twrp and 2nd bootlander before installing the rom.

thank you
Thank you for the advice. I appreciate it.
I've run into a new problem today, however. The device powered itself off and won't reboot at all. (It had a full charge). So I am off to do some research on how to fix this problem. UGH.

I didn't flash anything - just tried to root. After several hours of trying lots of fixes and googling like crazy, I was able to get the device to turn on. My WIN7 laptop was not recognizing the KFHD. I tried a different usb port on my laptop and it installed all of teh drivers and recognized the device.
I did go ahead and order a fastboot cable - and I'm glad I did. The day after I got the KFHD working again, it turned itself off again and would not reboot.
I spent several hours today trying to understand fastboot and how to use the cable and a few minutes ago, I was able to restore a system image and get it back to stock. I am waiting for it to charge up a bit and then I'll set it up again. I think it worked because there are no apps or anything installed as of now.
All I really want to do is have access to the Play Store and install an alternate launcher, so it looks and feels comfortable for my kid. He's had the kindle for almost a year, but doesn't feel very comfortable using it and its something he needs to use at school (where I can't help him). Once its charged up, I will re-root - following directions very closely!!!!!
Thanks for your help!

I would recommend you to install a custom ROM like CyanogenMod. Trust me,you'll love it. AOSP is much better than Amazon OS.

Kindle Fire HD 7 4th Gen - Can't access main screen or other profiles

My wife made the mistake of buying a Kindle Fire HD 7 4th Gen off of Ebay for my daughter for Xmas. I made the mistake of not checking it before Xmas was actually here. When I start up the Kindle, it comes on and immediately goes to the Settings page. There is no way to get to the home screen, download/install new apps, or change profiles. It appears someone tried to root this device and jacked it up. There is a notification for SuperSU Installer saying 'Tap to install SuperSU and root your device'. When I click it, it says 'SuperSU's su binary is not present, this is a fatal error'.
I dont need this device rooted, right now it is just a paper weight. Does anyone know how to completely wipe it back to factory? I tried the restore to factory settings, but that didn't do anything. I tried the First Aide utility, but the tablet didn't appear to recognize it.
Any help would be greatly appreciated.
Check for any updates to the device. If there are any, install them - this will hopefully reset /system, and then SuperSU shouldn't error out.

Thanks for the reply. There is an update, but it won't let me run it, it immediately fails. Our local Radio Shack says they may be able to fix it, otherwise it may end up as parts haha.

Are you able to plug the kindle into a PC and access its internal storage?
