[Q] i am stuck in a dark place with my kindle fire

i watched the video when i signed up so i really dont want to spam or anything like that but i am not too sure what exactly my problem is and if there are posts on it so i am going to ask for help.
i rooted my kindle fire and all was going well when i installed CM7 energy and my brother (i am not sure of what eexactly he did) he turned it off or something and then my android wouldnt boot, so i sorted this problem out and got it back to the factory default settings. then i put CM7 energy back onto my KF and now it comes up with the kindle fire logo, then goes into the CM7 energy launching icon and thats as far as it will go. i cannot connect it up to kindle fire utility, it cant see it. i tried giving it the fastboot commands and went through various methords for that. my computer doesnt even see it untill it starts trying to launch CM7 energy. could someone please help me?

Can you get into TWRP Recovery and clear the dalvik cache?

sadly i cant, it seems to have dissapeared when i tried to flash the new Rom

When you turn your Kindle on, what does the boot logo look like?

Should make a list of the ten most common mistakes 1. Should be using a recovery without the understanding of how to access it again.

OK I have an update to this issue. I reinstalled the drivers on my pc manually and now I can see the kindle on the Kf utility. But it can't seem to find any directory when I try any of the options. So if I try and install something it just says cannot find directory
And I never got any warrenty with it because I bought it on my holiday to America

It comes up with the kindle fire logo for a split second and then goes to the Cm7 launch screen with all the multi colour panel looking things turning

is your kindle fire logo come up first white kindle and blue fire? If so push your power button a few times to get a boot menu select recovery this will take you into twrp where you can factory/ data reset wipe cache wipe dalvik wipe system and select the rom you tryed to install swipe to install. might be best to locate this first before doing the wipes just a suggestion. after you flash rom flash gingerbread gapps select reboot then select system boot animation takes a bit be patient should boot to an adroid screen where you can sign into google.
Also if you made a backup you might want to wipe and restore that before moving on instead of reflashing
No white kindle or blue fire you can always try sending fff you must be connected to the internet to do so.

There should be some dialogue about fetching files if not kfu is probably useless to you at this point your drivers in devices manager should say andoid composite adb interface as well.

Yes my drivers are correct so that kf utility can see it, may I ask what for you mean by sending fff? And sadly it is the normal red kindle fire logo

So the KF Utility see your device, then run it to change your bootmode to recovery(5001) then install the newest version of FFF 1.4A.
From there do a factory reset then wipe Dalvik and system cache just as Thepooch stated. Then try re-installing your rom and stuff.

Use KFU to change your bootmode to recovery (5001) and reboot.
Once you're in recovery, use the mount function to mount your sdcard as USB storage and transfer FFF 1.4a to the device. Then use TWRP to install it. With FFF1.4, you can use the power button to easily access recovery and flash a new rom.
It sounds like your brother hit factory reset in TWRP and wiped out the system leaving the device nothing to boot to, hence the black (backlit) screen.
You could use KFU to install FFF, but it is ill advised. A small mistake in flashing a bootloader seriously brick your device to a state that would require pulling the back cover off.

You bought it on your holiday to America? Ok, so I guess that means your British? Sorry if I'm wrong. And you said on your holiday? And when you say holiday, you mean like a vacation. Sorry if I'm wrong, but I looked it up and that's what I found. So you bought it in America? So then I guess you can't return it. BTW Amazon provides a 1 year warranty that you don't have to buy. I'm not really sure what you can do, so I'll leave it to the other guys on this thread to help you out. Sorry.

right i tried to go into the recovery and it told me it couldnt find the directory but the kindle did restart, but never turned on thanks to low battery which im having a little problem with at the moment. i am going to charge it for half an house and turn it back on and try again.

right i have charged it and tried to put it back into recovery, it tells me that it cannot find the drive specified and when it restarts nothing changes its in normal boot

check your drivers again it needs to say android adb composite interface

Your helpers are suggesting you use KFU to switch the bootmode on the Kindle Fire to recovery (5001). If you can do that, the KF will (hopefully) reboot into TWRP the next time you restart the device. If you really want to figure out what's going on with your device, you should try using adb (and fastboot) directly instead of going to KFU to do it. Then you'd have a better chance of seeing what's actually happening.
This seems to be a very common problem where the system software has not booted far enough to accept adb commands and the KF cannot be put into fastboot mode. Your KF just might be in this very situation.
I suggest you take some time to read...
http://forum.xda-developers.com/showthread.php?t=1552547
so you have a better idea of what the posters in this thread are saying.
If you cannot get the device to boot TWRP or enable fastboot mode, you'll want to get a factory cable.

big update to this issue, i couldnt get it to go into recovery. so i just had a quick ponder and tried to flash the origonal rom using kindle fire unbricker, it then sayed a load of stuff whic is typical but then it said changing offset to 0x something and then the kindle screen changed to the kindle fire logo and stayed there. so i then plugged into into kindle fire utility and i was able to put it into recovery. now i have it in recovery i am going to do everything you all have said and really hoping its going to work.
Thank you everyone who has helped! and it seems to be coming to a happy ending

get yourself a bootloader first and be careful what you just did could wipe out your recovery and your newly installed bootloader thats what flashing stock will do. http://forum.xda-developers.com/showthread.php?t=1632375 bootloader here.
But heck if it does boot into stock hopefully a working form of it.

problem solved
right after lots of redoing things, updating things testing roms. i can now say that if any body is stuck with the issue i have (e.g. stuck at the logo) they can open kindle unbricker and start the flash update. it should change there kindle to stay in a kindle fire logo screeen when they turn it off and on. from there they should connect it to there PC and open KF utility and install TWR and the kindle should go into that screen. then once there, factory reset and then it should go back to its normal self (before root) then i recomend downloading the new amazon update 6.3 and installing that. then flashing a new rom because this has worked very well and i am currently on AOKP i think its called, milestone 5 and it is amazing, i recomend it. thank you everyone for helping me, i appreciat everysingle comment and you lot are mirrical works for noobs like me!

Stuck in boot loop after failed root.

i was curious to get get android market on my kindle today.. and looked up how. i used the kindle fire utility to root it. then my KF it started to go into a loop of the boot logo. it just flashes on and flashes off over and over again.hard reset doesnt affect it at all, it wont even turn off unless i unplug it. it doesnt show up on my computer either.
i dont know if this helps but when i ran the Kf utility it said 'findstr' not recognized.. blah blah blah. and it didnt give me the 1234567 options on there. i just typed in '2' and pressed enter because thats what the video told me .-. it doesnt have a triangle, or a blue screen logo either just the kindle fire logo flashing off and on. I honestly am lost. please keep this noob friendly
i am running win 7. 64 bit.

josepho1997 said:
It seems like your stuck in fastboot mode. You need to reinstall the drivers manually and then go into KFU. Press 1(bootmode)and 1(normal). If you still want to root it, when it gets to installing fff, and if it says <waiting for device>, you need to do a hard reset and your Kindle, unplug, plug it back in, and manually install the drivers. Then it will finish rooting.

How do you reinstall the drivers manually? and also when i go into the kindle fire utility it doesnt give me 1,2,3,4,5,6,7 options... it just says findstr is not a recognized as an internal or external command, operable program or batch file. and another thing i tried another utility on here and it said it said my device was not found when i plugged it in , is it because it turns off every 5 seconds?

First before you mess with your drivers shift+ right click on the tools folder in kfu select open command window here power your device off completely leave it unplugged type fastboot -i 0x1949 getvar product when it says waiting for device plug in your powered off kindle it should then power on in fastboot mode if you get the response product: kindle then type fastboot -i 0x1949 oem idme bootmode 4000 it will say okay hopefully the type fastboot -i 0x1949 reboot it should then reboot in normal mode
Edit: hit enter after each command

Sounds like there's some sort of PATH problem with your setup, which is why KFU won't work properly. You'll have to manually use ADB/fastboot commands if you want to get things done.
About it turning off constantly, it's probably out of battery. Use the stock wall charger (it provides a greater power output, don't bother with USB or a random clone) so it can refill some. The bootloops may be due to a bad boot mode, but it's a bit hard to pinpont with your description of the issue.
You may want to have a read here, it'll help you to better understand what's going on and how to express yourself about the problems you are experiencing: http://forum.xda-developers.com/showthread.php?t=1552547

You might have corrupt drivers. Here's how to reinstall them:
Try going to your Control Panel >> Device Manager. If you see an entry for "Android Phone," (Android ADB interface) delete it (and any associations with Portable Devices >> KF or Kindle Fire).
Restart computer.
Then go to your KFU utility folder, open "install_drivers.bat" (right-click "Run Administrator"). This shouldn't take long at all.
You might want to restart here too after.
Then open KFU utility, plug in Kindle - if all went well here, you should read something along the lines of "Online" and "4000".

I am a similar situation
Hi Guys,
I rooted my KF with no issues, was able to copy the Jellybean and Gapp zip file to the SD and thought I flashed with no issues. Then rebooted. Now the KF is stuck in a boot loop. If I boot to recovery, that works and allows me the recovery options. if I boot up to normal, it constantly reboots, if I boot to fastboot, it displays the Kindle Fire logo and says "press power button to boot menu" at the bottom and does nothing else. My computer recognizes it as Android ADB interface but will not allow to access the SD ram. Any help would be greatly appreciated.

It's usually better to start your own thread here on Q&A.
Are you able to access the SD Card from TWRP? (Mount USB)
If so and the ROM is still in there, wipe cache, dalvik-cache, factory reset and system, then flash/install the ROM again (don't install gapps yet) and reboot. If it boots all the way to the desktop, reboot to recovery and install gapps.
You may also want to check the ROM's hash.
You haven't mentioned what versions of TWRP and FFF do you have, either. Hopefully 2.1.1 or 2.2 for TWRP and 1.4a (blue "fire" on the kindle fire logo) for FFF.

Thanks for the info and sorry for the incomplete initial info. I will check this as soon as I get home and can work on it again.

Thanks for your help. It turns out that I didnt even have TWRP installed. Thats fixed. I was able to get roms installed and have different problems. (Will start a new thread in another area) Thank you very much for your help.

[Q] Kindle flashing and factory software

Hi everyone, I have two kindle fire, I messed with both of them.
I've root them the first one has the problem with the yellow triangle logo stucked. And the other one I've tried to reset it to the factory settings and everything was cool until I hit the TWRP utility and I think I erased everything.
I've see tons of posts regarding rooting and troubleshooting related to rooting and i'm pretty sick of rooting, I think that 3 months is sufficient time, please DON'T POST anything related to rooting.
I'm here asking if anyone knows how to flash all the data ofthe kindle from the pc and been able to install the factory software, firmware (I don't know) from scratch from my pc. Anyone, please?

The first one is probably stuck in fastboot. Try giving it a go with "fastboot oem idme bootmode 4000 && fastboot reboot".
For the second one, "I think I erased everything" is as descriptive as not wanting people to post about your procedure is helpful. What exactly is going on with it? For future reference: http://forum.xda-developers.com/showthread.php?t=1644970
You should also update both FFF and TWRP on both devices once they are working normally.

If i may suggest flashing modaco first after a good wipe everything except your sdcard I believe this will make a smoother transition if you desire to return to stock before returning to stock always do a good wioe to remove remnants of previous roms download the latest stock bin and rename it to update.zip do not place it in any folder just at the root of your sdcard flash in twrp this will also wipe out twrp and fff I really dont recommend doing this lots of people fail at doing the procedure correcty modaco is stock with only the market added try this approach first then you can retain fff and twrp for custom backups.

Ok, so, I've been investigating and what I'm really looking is to erase ABSOLUTELY everything from the kindle sdcard, system, etc, everything. And I'm looking for a method to sideload from the pc the orginal stock ROM of Kindle Fire. Any clues, directions? Any fully functional software?
I really, don't want to try the adb commands (I've tried them before), nor follow any tutorial about root troubleshooting.
I'm really sick of them and of all that mal-functioning software that you have to download(Eg. Not-responding superOneClick, kindleFireUnbrickUtility saying in one line <No device found> <Processing something> <Congrats, your kindle is good to go! (When it's not)>, Eternal loading Android Commander)
With all due respect I DON'T want any more of those, as I said, 3 months is sufficient time, I feel so frustrated.

Read from "Reverting to stock software". You can manually rename the file and then copy it into the KF instead of using ADB for it, just make sure the extension is .zip and not .zip.bin (Windows hides extensions per default settings).

To restore back to full factory
1. Download Kindle Fire Software Update Version 6.3.1
2. Rename the file to update.zip
3. Get in to TWRP and mount USB drive
4. Copy update.zip to Kindle Fire
5. Unmount USB drive
6. Do factory reset, then wipe system cache, and dalvik cache
7. Flash the update.zip
8. Let it bootloop about 3 times or so...
If you want FFF and TWRP then flash Stock 6.3.1 Basic from TWRP. This has no root or gapps.

When trying to execute the adb shell commands all I get is:
- exec 'system/bin/sh' failed: No such file or directory (2) -
I've also tried, fastboot update | flash | boot | flash:raw
This is with one kindle, with the other one, I can't even get the PC to recognized it as a USB
Is there any tool, that really erases everything and take the stock ROM to be installed again? Software, script?

Ahh, that's a bother. It's a pretty annoying error. Could be something messed with your TWRP (I'm assuming you tried the commands from there).
There isn't one, but there's really no need for it... you just rename the ROM to update.zip, wipe cache, dalvik-cache and factory reset, and install update.zip. If you just want to flash stock because you like it better for whatever reason, you could also just look at the MoDaCo custom ROM instead, as it is stock based.
As for the other KF... you can't get it recognized, from where? The ROM? TWRP? Fastboot?

Both of the kindles, are damaged. I can't access them. I just can access one by USB.

For future reference:
This user's issues have been partially dealt with.
The first KF will require a factory cable to be fixed.
The second KF was soft bricked (there were a few corrupt partitions) after a bad flash attempt of the stock ROM. Luckily, FFF was still installed, but the Windows fastboot drivers weren't. Reinstalled FFF+TWRP from Firekit, and then fixed the partitions, wiped and flashed the stock ROM.

Ok, So, I have the factory cable. How can I test its Ok?
I have another question, the kindle is pratically empty no system, no sdcard memory, probably corrupted ¿How do I use the factory cable, to format the Kindle and install the Stock ROM again?

With the KF off and unplugged, type "fastboot getvar product" on a shell (KFU/tools).
Then plug in the KF using the factory cable. If you get anything listed or returned, it should be working fine. Otherwise, if you wait a few seconds and still nothing, you'll have to check the drivers to make sure the correct fastboot ones are installed.
To check the partitions, you can just "fastboot boot twrp.img" to load a TWRP into memory, and then "adb shell parted /dev/block/mmcblk0 p" to print all partitions' information.

Well, I'm at my job now. So I will try this at home, but the shell is not working since system/sh (shell) it's not in the Kindle. I was trying to boot it yesterday with "fastboot boot twrp.img" and nothing. I also tried: "fastboot getvar product" and nothing but I only used the console. Anyway, let's see what happens...

Quick question, I've read that the factory cable puts the Kindle straight into bootmode, ¿So the color of the power button, has something to do with it? ¿I mean how do I know the kindle has entered factory mode? ¿The orange light is an indicator? (With a standard USB Cable I only get the green light with the power button, with the factory cable I first get green light, then orange light)
I've also read that if I can see the Kindle fire logo, the bootloader is Ok. Hence my Kindle is OK, but I can't enter fastboot mode. ¿Can anyone confirm this?

It'll get stuck in the bootloader screen, and fastboot commands should work as well, provided the drivers are properly installed and working.

OK, I've finally made myself a working factory cable. And in the device manger I can see the kindle listed as "Android phone" and in that root it says "Android ADB Interface". Look like drivers are not working. Where can I download them?

Those are the proper drivers for fastboot you should be able to use kfu to send twrp and fff to the device if that doesn't work you will need to fastboot flash them

All I get is < waiting for device>. Looks like the drivers are not installed.

Simply hold the power button down while connected when it says waiting then power it back on and it should send also try unplug replug when it says waiting

[Q] Demo Kindle Fire ADB Help

I know that this has been gone over multiple times, but I can't get any of the other threads to help so I figured I'd post my own.
Basically, I worked for Best Buy for awhile, rooted the demo Kindle Fire we got at work and that was that. So I figured I could get a demo Kindle Fire off Ebay and just get it rooted and Rom'ed. Well, I can't get the damn thing to be recognized by my computer in ADB.
I've literally tried everything, I've changed the android_usb.ini file to include the 0x1949 and the other file to have the kindle fire in it. Then I tried to point the Kindle to the new file that was changed. Everytime I update the driver it stays as the MTP Device and I can't get it to ADB Composite. I've tried the KFF and that doesn't work either. Uninstalled drivers and reinstalled with no success.
Also, it seems that every time I plug the Kindle into the computer it reinstalls the Drivers.
I do have a Factory Cable on the way so I'm hoping that that will work for me if nothing else does.
Thanks in advance all.

As long as the factory cable you speak of is the fastboot cable that is all you will need. Simply get it into fastboot, flash FFF and TWRP, transfer a Rom.zip and Gapps.zip to the sdcard, do a full wipe in recovery minus the sdcard/external storage. Flash Rom, flash Gapps and reboot. if you get it properly into fastboot your driver will read Android ADB interface. If your running windows 8 you need to disable driver signature verification in order to install the driver.

Thanks! It should be here today so I'm excited. I read all of what you've posted multiple times now in other threads, I just haven't been able to get it into fastboot so I'm really hoping that fastboot cable works for me.
Thanks for the quick reply Pooch.

Well. It's bricked. Couldn't get it to boot into twrp. After trying for awhile I decided to just flash fff as I knew the recovery was there. I get nothing now. Completely black screen and no led on power button. I've tried the whole firekit short usb with no luck. It gets past the first part but then just sits at waiting for device. So I'm lost. Is it fried?

[Q] Installing 2nd Bootloader on 8.4.3

Has anyone tried it?
I have only just picked up my KF8.9, but have successfully rooted it. However, chickened out of installing the 2ndBootloader and TWRP as it seems that some people say it still works and some people say it doesn't.
Don't want to brick my shiny new toy, and don't know enough about these devices to know if the existing guide (http://forum.xda-developers.com/showthread.php?t=2128175) is still correct for 8.4.3.
Any info appreciated.
Thanks

:good: I would like to know this also

If trying to accomplish this under Windows, the key is to have the proper USB driver for your device installed AND ADB communication working. Once I managed to confirm this, I used KF First Aide to install the 2nd bootloader + TWRP under 8.4.3 without any issues.

If trying to accomplish this under Windows, the key is to have the proper USB driver for your device installed AND ADB communication working. Once I managed to confirm this, I used KF First Aide to install the 2nd bootloader + TWRP under 8.4.3 without any issues.

How did you confirm that you had the proper USB driver installed?
Currently with the drivers I have:
I can see my Kindle in Windows explorer
I can see my device as an "ADB Device"
When the Kindle is off I can type "fastboot -i 0x1949 getvar product" to put my device into Fastboot
Is that about it?
Thanks again.

ADB is working just fine for me under 8.4.3 but each and every time I attempt to install the 2nd bootloader and TWRP it red screens on me. Could you tell me the steps you followed with KF First Aide in order to get it to work? I can't seem to find information here at all.
Thanks,
Ray

You can install the proper USB drivers with option 12. in KFF, or manually by following instructions described here: http://forum.xda-developers.com/showthread.php?t=2069117
You can also check ADB communication with option 11. in KFF. If a device ID is displayed, you are in business.

I simply used option 41. in KFF. You need to be rooted first, use option 21. in KFF to do this. You may be prompted to manually grant permission to SU on your Kindle, so don't just run this and leave the tablet alone to go for a cup of coffee...

to fix it i used a homemade factory/fastboot cable turned off the kindle and used option "25. Restore The Kindle From The KindleBackup Folder" then plugged in the kindle to the pc and said yes only to the boot partition one and it booted up fine. You would have to have made a backup to your pc first.

Well I am at this point myself. Just ran Option 41 and ended up with a Red Screen.
KFHD8.9
OS 8.4.3
Rooted w/ Bin4ry v30
Android SDK installed in Win7 PC; ADB communication working fine with Kindle
ADB and Fastboot were working fine per KFFirstAide
executed KFFirstAide option 41... Kindle went into Fastboot mode and then rebooted into Red Screen.
Any ideas on next steps?

I didn't have the Android SDK installed, as I used the ADB drivers provided through KFF. Perhaps going back to 8.4.1 (from backed-up .img files) or an earlier version and start from there?
