I bricked my KF GOOOOD this time

I have had a Kindle Fire since they day they came out. I immediately disliked the stock Rom so I ran the kindle fire utility and installed Fire Fire Fire and TWRP, rooted it, and installed CM7 Rom which has been working great. Transferred files and programs between my PC and Kindle with no issue for months. Now with all the ICS roms available and working I decided to try and upgrade to one of those and thats when everything went wrong. Its in a bootloop and the triangle appears, fades, lights up again and immediately boots to TWRP. I have flashed the entire kindle using TWRP trying to get everything off of it. Upon plugging it into my PC BRIEFLY when the triangle logo pops up I get a "USB device not recognized" on my PC. I have tried using KFUtility to reinstall drivers, tried uninstalling n reinstalling drivers but the same thing happens. I cannot use TWRP to mount at all, nothing happens. Kindle Fire UTility keeps saying adb offline, CMD adb devices also results in 0 devices found. I have tried putting it on normal boot using both ADB and KFUtility and it says "wait for device" and nothing ever happens. Any idea? Not even sure if I have a rom installed on my kindle anymore but my PC wontread it so I cannot push another image to it. Got a plane trip on Saturday and would love to have this working to kill the bordom lol. Any advise would be greatly appreciated.

It sounds like your bootmode is set to recovery. An easy way to fix this is download FFF1.4 to your computer and use the mount function in recovery to place it on your sdcard.
Flash it in recovery as you would a rom except don't wipe anything. When you reboot, hold the power button like you're trying to enter recovery and you'll be given the option to reset the bootmode.

Thank you so much for your advice but there in lies the problem. Inside the recovery console i choose to mount it and nothing happens. My PC will not let me access the kindle in anyway at all, either mounting the SD Card or via ADB/KFUtility.

Generally, the only thing that would prevent adb/kfu from communicating with the device is the drivers. Make sure they're installed properly. You may have to uninstall them (delete if applicable) and reinstall them.
Follow the instructions in this guide to install and verify your drivers.

K heres the latest (we r making progress!)
I got my device to be detected by my PC and used KFutility to change it to normal boot. Now instead of booting into recovery everytime it boots normally.... to a black screen (guessing my rom is shot or I deleted it while playing with it). The issue is the ONLY time my PC recognizes my kindle is for a .5 second period when i first turn my KF on and the yellow triangle appears. I can use this window to change it to normal bootmode, reinstall TeamWin, stuff like that, but i cannot mount it so I can transfer or adb so I can push. You can watch device manager and it'll pop up ADB android phone or whatever it should but poof, a second later gone.

Get your device drivers working so you can use adb. Follow the instructions in the post below...
http://forum.xda-developers.com/showpost.php?p=26144447

That is excellent advice and I wish it would work but I cannot pull up ADB once in TeamWin. Keeps saying no devices. As i said my PC detects it and ADB will detect it for .5 seconds on the orange triangle. Once the orange triangle disappears and it either boots to blackness or boots to TeamWin ADB stops recognizing my device. But I will play around with your suggestions once I get off work and let you know what i find out. Thanks again for everyones support.

Frozen screen during rooting
Hi,
I am new to the forum. I have a kF screen stuck (where it says 'kindle fire') while I was trying to root it. I tried hard reset, charging for half hour, calling AMAZON...nothing works. The screen goes off if I hold it for 20 seconds but when I put it back on same thing. I was trying to root it with 'fastboot (?). Is there anything at all I can do? Thanks.

[Q] Kindle Fire 2 brick: WHITE triangle on boot

Right, so, I've done some googling and some searching about here and there but either I'm being dense and the solution is really simple, or nobody's done what I've done with this tablet before and, again, I'm being dense. Here's my issue:
Kindle Fire 2 (2nd gen, also second-hand) tablet: stock, rooted, that worked fine with the tool by bin4ry.
Rebooted after that, verified root was working, adb and fastboot perfectly fine (sidenote: linux user, no shonky Windows drivers at fault here)
My ultimate goal is to get CM on this device, so, started after this to follow the instructions in this thread regarding getting the second bootloader on the tablet.
Realised I need a factory cable, ordered, delivered, works but not all the time, I'm not sure if it's a dodgy cable or not but did get into fastboot.
Got new bootloader installed, saw Kindle Fire logo in blue. Proceeded to boot the stock rom after this and use adb push to put the CM 11 zip and the gapps zip files on /sdcard.
adb shell, su, reboot recovery, intending to boot into TWRP to flash new rom
Tablet reboots, but is now stuck with the stock boot logo (orange) and then a black screen with a white triangle and exclamation mark on it. I haven't seen any references to this particular delight.
Fastboot cable does not, no matter how I fiddle with it, put the tablet in fastboot mode. Holding down the power button for five minutes did nothing.
I've read that if it turns on, it can probably be recovered, but I don't know what to do from here. Can anyone render assistance?

So, after much fiddling, I discovered that my problem was actually that my fastboot cable was loose in the microUSB end, and not contacting properly with the pins - thus not sending the tablet the requisite signal to enter fastboot mode.
I've successfully got TWRP onto the fire and thus CM 10.1 now.
I hope this update helps anyone who finds themselves in a similar situation; fastboot still works, keep wiggling.

I had this problem with a 2nd gen Kindle that was also second hand.
Phoned Amazon UK, described the problem (not mentioning I'd done it myself) and they replaced it.
Seems there's not a lot they won't replace.

[Q] another boot loop post..

Hey guys, before I begin, yes i read the '[HOW-TO] Before asking for troubleshooting help...' page as well as the '[GUIDE] Kindle Fire For Beginners' page, and am still in need of a bit of assistance due to my hilariously lacking knowledge of the workings of electronic equipment. :silly:
I just dug my kindle fire out of my dresser drawer where it has been sitting due to being 'bricked' for quite some time (stuck at the boot logo - white kindle text and orange fire text shimmering on a pure black background - holds a charge but is indefinitely at this screen). It is completely stock, having not downloaded or installed any ROMs or any other software, and initially began experiencing this problem the morning after running it out of battery while downloading a few books and games one night. I promptly plugged it in, went to bed, and woke up to it in this state that next morning.
I have tried downloading Kindle Fire Unbrick V1.1 by ZombiePiratez and running that to fix it, but it does not recognize my kindle fire. So, i downloaded Eclipse ADT with Android SDK for windows and followed some instructions i found for getting it to recognize my kindle as "Android Composite ADB Interface" in hopes that then the unbricking tool would recognize it and work its magic for me. But it didnt. I imagine this is because the process that I followed is flawed.
My question is, if i were to buy a "factory cable" would I be able to unbrick my kindle fire without having to do any of this command promp shamanism thats clearly over my head? Kinfauns states in his guide that "With a factory cable, unbricking just comes down to "plug it in and flash new stuff" in almost every bricking situation." But what does 'flash new stuff' mean; should I have picked that up from the guide as well? Or could I just use the factory cable in conjunction with ZombiePiratez unbricking tool to get back to the factory settings?
Thanks in advance for any pointers

Hey @sd_shadow !
Thanks for the link to that, the videos you've created make it possible for even someone with my level of tech knowledge to work through this problem. Immensely better than trying to follow a written guide
Anyway, I finally got my fastboot cable and followed the steps in your videos to the tee, however I'm still encountering one small problem. When I get to the point where I'm installing update-kindle-prerooted.6.3.3.v1.zip in TWRP by swiping across the screen, it runs until it gets to the line thanking paulobrien and two others but then promptly freezes (or so i assume since it doesnt continue on and the loading bar halts in its tracks). I decided after a few tries to just hold the power button to get it to shut off and then booted the kindle in normal boot mode - and it worked! - despite not being able to complete the process as shown in your video. But this concerns me, as I do not have any of the additional apps shown in your video (not that this truly matters to me) and under settings -> device it shows that I am running version 6.3.1_user_#####. So I have two questions:
1) Did the fff and twrp processes work, but the 6.3.3 update fail thus enabling me to use my kindle as a v6.3.1 device again?
2) Will it harm my device in any way (e.g. re-bricking) if I just call it good and use it as it is now?
Thanks for all the help so far :highfive:

1 yes installing TWRP and FFF reset boot, and allowed 6.3.1 to boot normally
2. the only problem should be that, when connected to wifi, update will redownload and try again once a day or so
Kindle will reboot to TWRP, but update should fail, if that does not bother you it is fine
3. what twrp version did you install? says in twrp if you are not sure

I installed TWRP v2.7.1.0-blaze because that is what you used in the video, even though i had read that 2.2.2.1 may be preferable for stock unrooted kindle fires. I did this so that I could follow your video exactly without having to change any steps except for switching otter to blaze in the cmd promt code I inputted.
Also, as I write this, Ive realized that I still may have made a mistake and installed one of the alternate test files for the 6.3.3 prerooted update and not the complete file itself, so ill get back with that info.

Yeah, i installed the alternate test file the first time :silly:
Went back through and followed your instructions to the 'tee' again and its up and running.
I do have one more question though; when I am using the device I dont get very far before selecting an application or making another command causes the screen to go black, only displaying the time and settings option at the top and the home button, back button, search button, etc at the bottom - none of which respond when selected. This happens with both the go launcher and the kindle launcher, and each time the only way I can stop it is resetting the device... Any suggestions to counteract this?

Bricked Fire TV, what are the options?

Well this day has been a long time coming and it finally happened
In short I had reflashed my device with RBox prerooted rom via TWRP without any issues. In order to use certain applications I was using "hide my root" only to find once the su binary was hidden the application was unable to restore.
When I shouldve reflashed the rom I decided to take a short cut and install Super Su directly via TWRP, big mistake.
Device is now stuck on the Amazon logo (not the colourful splash screen) I've attempted to access the system recovery menu via the keyboard hotkey but the keyboard is unresponsive, in fact there seems to be no power coming from the USB. Which got me thinking, this is more than likely related to drivers, perhaps using an older keyboard with P/S2 and a USB adapter would work. I am yet to try this.
Any advice?
Would opening the device and unsoldering certain components perhaps initiate a reset of some kind?
Just throwing ideas around at I'm stuck with a paper weight
Any suggestions?

http://forum.xda-developers.com/fire-tv/development/firetv-2-unbrick-image-t3313349
This should help. The shorter option didn't work for me. I've used you the longer on mine and two other peoples ftv. It's worked every time.

I have a Fire TV 1, do you know of there are any recovery images available for this edition

Have I bricked my FTV 4K stick beyond repair?

Sorry if this is posted in the wrong section, I am never quite sure where these sort of queries should go
To cut a long story short I unlocked and rooted 1 of my FTV 4K sticks, I was struggling with an issue on 1 and ended up installing a Magisk update. I know there are warning all over the forum about this please put it down to a lack of experience.
On reboot it just comes up with the black screen and the white amazon logo, it stays on this for about 2 minutes then restarts to the same black screen. i.e. its caught in a boot loop. It never gets to the white amazon screen.
I bought myself an OTG cable thinking this would get me to twrp so I could go into recovery and wipe it and start again or something, but even with the OTG cable plugged in it still does exactly the same thing. I have tried the same OTG cable and entertainment keyboard setup on another FTV 4K stick and it gives me the 5 second boot menu to get into recovery.
I am guessing I have killed it beyond repair? Is there anything else I can try to do?
Thanks

you need a usb keyboard and then you need to press a combination shown on youtube: , Don't be afraid it is very hard to do it but i can confirm it works 100% for sure!! The timing for holding the key press is all that matters to be successfully...
Try different timings if it's not working on the first run but you need then to hold the buttons for very long time until your fingers feel dead....
..im not sure if adb is working in "safe mode" you need to test that. If yes - you could use "adb reboot recovery".
2. you need to reflash Magisk in core mode.

You haven't killed your stick, install fastboot drivers and app.
Connect your stick to your pc via usb.
Enter
Code:
fastboot devices
when you see black screen with amazon logo, it should be inside fastboot mode
(If somehow you flashed update to boot.img as written in the guide)
If you see the stick in fastboot mode,
Pull twrp from kamakiri.zip
Place it in fastboot folder
Enter
Code:
fastboot flash boot boot.img
(boot.img or whatever the name of your twrp image)
Code:
fastboot reboot recovery
It should work, if not you can use shorting method again.

Thanks very much both, I will have a play around this evening when I get home from work and the kids are in bed, hopefully with the info above I can get back to recovery again.

Thanks for the help gents, in the end I had to do the shorting method to get the stick to do anything. It took about 6 attempts before kamakiri script even registered it as anything being plugged in, it just kept saying wait for boot.
Once it realised the stick was present and shorted I was away though, I have ended up having to factory reset and wipe everything so will need to start again with it but I am just pleased I don’t need to shell out again for a new stick.
Thanks again for your help
