[Question] Kindle Fire is possibly dead.

Guys,
Details: Using Windows 7 64 bits, on a notebook.
Here is the full history of my brand new brick... call me stupid.
Second day with my Kindle Fire, I tryed to root my kindle fire.
Downloaded the KFU 0.9.5, instaled the drivers.
But the KFU wasn't workig... I only was getting the ADB offline status and the "waiting for device" message.
When I realized that the drivers I had were from my Motorola Milestone.
Next step: Uninstall the wrong drivers, and reinstall the new ones.
Only with this i could get the device to work with KFU.
Open the Run application at KFU folder.
Choosed option 2: Install Permanent Root with Superuser.
All worked fine until i get the message "with great powers come great responsabilityies" press any key to continue...
[EDIT: Tried to install Gapps extras... I don't remember if Kindle was dead before this or after]
The Kindle rebooted, got to the screen with the "kindle" word, and died.
Since that I'm getting no power on, no led lights, no response when connected to usb... nothing.
What should I do?
Go to Motorola Tech Support (here in my city) and try to use a factory cable?
or
I can only put my hopes on USB Boot Mode?
Guys, thanks in advance and sorry for my english, I certainly made some msitakes.
Or I can try Firekit?

That's strange, installing the wrong device drivers on your computer shouldn't affect your Kindle.
What it really sounds like is your battery died in the process of installing the FFF bootloader. How was your battery before you started? Have you tried holding the power button for 20 seconds for a hard shutdown?
As far as I know, the only thing that will cause power on issues is a broken bootloader. In which case, USB boot with firekit is your only option.

I guess I had at least 50% o battery charge, or more... I can't remember...
If I push the power button now, the Kindle will get warm, as if it was in use. And if I hold for 20s, will shut down...
I don't even started to install de fire fire fire bootloader, I installed the permanent root with super user and then went to install GApps. I guess my kindle was shutdown before Gapps install.
What should I do? Test the factory cable first?
When you say that I have to use Firekit, you are saying that I have to open my Kindle?

Left the Fire charging for at least 12 hours.
Tried to power on, to hold 20s and nothing happened.
I'll gonna try this:
Fix power on problems: If the Fire's screen never seems to turn on, you may have wrecked the bootloaders or the partitioning. Fortunately most of the time this results in the CPU falling into the low level USB boot mode. Use the "usb_fix_parts_and_install_fff_twrp" to rebuild the flash enough to boot TWRP. You don't need to use the USB shorting trick for this one, just power up the Kindle after running the script.

My question is: I'm running Ubuntu within VMWare tools. Can I boot from usb stick this way?
Gonna try this before I use factory cable or open my Kindle Fire.
EDIT:
Reading the FIREKIT Topic, this post: http://forum.xda-developers.com/showpost.php?p=25814062&postcount=26
My issue is kind of different from his... I'm guessing I'll have to open my Kindle anyway... Started yesterday, but I was messing with the case, gonna find some proper tools

VMs will not work. You have to create a bootable Linux LiveUSB thumb drive.

If you already have a working Ubuntu installation, you don't have to make the USB stick. You can just run the fk binary in your Ubuntu setup.

I've tried it on a VM and had it confirmed by other users that VMs aren't fast enough to detect the USB in time. From what I've seen, it has always been suggested to either use either a straight Linux install or a bootable LiveUSB.

I guess it might depend on the VM, but I disagree with the generalization that VMs are too slow and have issues with USB.
The only thing I've seen is that Oracle's VirtualBox USB implementation breaks adb. I've never tried VMWare, but Parallels Desktop for both my Ubuntu and Windows setups work perfectly. Never had an issue.

Anybody who is going to be modifying the basic software of their Kindle, or even just root it and play around, should have a factory cable. Xda member SkOrPn makes good ones at a reasonable price and ships them quickly. See http://forum.xda-developers.com/showpost.php?p=25725396&postcount=338.
(From what you wrote earlier, I presume that you don't yet have convenient access to a factory cable but would have to go out of your way to use one. If you do, in fact, have easy access to one, I can't imagine why you wouldn't try using it instead of putting a lot of effort into looking for alternatives.)

All the scene leads to this... USB Boot.
About the USB stick, I was making some confusion about it.
But, I´ll gonna make one stick right now.

Guys,
I made the usb stick... just figuring how to open the kindle fire, without ruining the case.
But I guess today I'll made the short trick.
Question: I'll keep the 6.3 stock room that i tried to root? Or I'll have to download another ROM?

Is there any know issues about firekit compatibility with ubuntu 12.04?
Like this here? http://forum.xda-developers.com/showpost.php?p=25918331&postcount=10

I WON!!!!
I'M BEOWULF!!!!
Serious now...
Firekit method, with short trick... keep trying... until you find the right spot for the shor... and will work
EDIT:
THANK YOU GUYS!!!
I wouldnt be that happy without your help and your knowledge... You're the real Beowulf!

[Q] Tried to put Fire back to Stock and now bricked

I looked at almost every thread I could see that sounds like my case but in every one the device is at least being recognized by USB on the computer, in my case it has absolutely no recognition.
I had custom gedeROM. gf didn't like it and so I decided to go back to stock.
within TWRP I did Factory reset, then installed the stock bin file that i renamed to update.zip. Install went through properly so I restarted.
Now it is frozen on Kindle Fire boot screen, and it won't go further. Attaching it to a computer with USB will power the Kindle on but the computer will not detect it, tried on 3 computers, Windows 7 and Linux. I have tried to use all forms of unbricking, everything except opening the Kindle. But since the device isn't being recognized by USB at all on any system I don't know what to do.
With a Factory cable help with this?
Thanks for any help.

In Linux type lsusb and see if your device is shown. It my be named something weird.

Did you have adb and fastboot setup on linux when you tried?

I'm pretty sure I did, I used the firekit and that didn't work as well. how do I check if adb and fastboot are for sure running when in linux?

when i lsusb, it just sees my usb stick i booted ubuntu from

Installing Amazon's stock update.zip gets rid of FFF and TWRP, so at this point, your only choices are either getting a factory cable (recommended) or cracking open the case and resorting to the USB short trick + firekit.

OK, I have an order for the Factory cable coming so hopefully that will do the trick. Thanks

[Q] Bricked ... tried most things ... need some guidance

Hi,
Some background - I've been tinkering with android roms on phones for a while, and thought i'd give it a go on my Kindle, which I hardly ever use with the stock rom. I have a very low level of understanding regarding rooting, etc., but generally I'm good at following instructions (until now!)
So everything was going along nicely. Because I hardly ever use the device, I decided to do a full wipe before installing the new rom. Then, when I went to flash it, it turns out that I had forgotten to copy the new rom onto the SD card. In a moment of temporary insanity, I turned the device off (don't ask me why, I can't explain it).
On restart, the device now gets stuck on the logo screen. KFU tells me that the device is online, but boot status is unkown, and it can't change the status (although it does reboot the device when I try to put it into fast boot mode- but it doesn't actually 'fastboot').
If I try to reinstall TWRP or anything else, I get the 'exec system\bin\sh failed' error. The Kindle unbrick utility is unable to help.
I did some research and it kept pointing me to a factory cable, which I duly bought off eBay. When I use the factory cable, the only difference is that the boot sequence is slightly different (different levels of backlight) and KFU can't recognise the device at all - it says its offline.
I have no idea if the factory cable I have bought is any good - it might be complete rubbish.
Can any tell me if there is a simple option I have missed? Is trying fixes through Linux the only option? Will I have to open my kindle to fix it? I've already spent a heap of time on it, and I'm just about ready to call it a paperweight. Any help would be greatly appreciated.

I`m a little confused so file me in. Do you have access to recovery? with your type of error "exec system\bin\sh failed" a factory cable is indeed needed to reinstall twrp and the bootloader, unless you can access TWRP and mount your sdcard and transfer a rom. If that is not possible then you have some kind of mounting issue. So I still wonder what happened to your recovery and your bootloader? For me yet not everything is meshing to well. No bootloader, no acces to recovery, kindle just boots to logo and no further. Does the logo flicker and brighten and dim at boot? Yes very likely you will need to run linux on a live usb then run soupkit on it. Still you may still need a real factory cable not one half **s one from ebay you can find that here http://forum.xda-developers.com/showthread.php?t=1392693 from user @SkOrPn no one can beat what he does I`m sorry. As for linux and soupkit the where and how is here http://forum.xda-developers.com/showthread.php?t=1850038 . Unless you get easily confused then try the iso I created with some fairly easy instructions soupkit is ran already simple create boot and use you can find that here http://forum.xda-developers.com/showthread.php?t=1413358 post # 7 make no mistake that this is only for the kindle like the last person I helped with this setup. This is your best route to get your kindle fixed sounds like it could still be a combined effort cable and soupkit .You will know when you hook your kindle up and run some of the features in soupkit if your device is truly online or if a cable is needed. If you run my iso teamviewer is also installed so it provides a nice edition for assistance if you want someone to see what you see. If you choose to run soupkit then the par for instructions differ from those of my iso.

No, I can't access recovery at all. When I use the factory cable, there is no flicker, but all other ways (standard cable, no cable) there is a flicker and it brightens. Either way, it just hangs on the logo.
I suspect that the factory cable is not all it should be ... I will probably try the @SkOrPn option first, then work my way through the other options you mention. I had kind of figured from reading other posts that this would be the case ...
Thanks for taking the tiime to help.

There is no flicker because your likely in fastboot the lack of recognition is drivers which can easily be solved using linux and soupkit. Otherwise straighten out your drivers in windows by running the driver bat packaged with kfu. If your on XP it`s a fight to the death to try to sort out unsigned drivers on that os. Sometimes I can get it fast other times it`s pointlessbut a huge hassle nonetheless. Attempt to fix your drivers while using the factory cable you have maybe you will get lucky.

Fixed! Thanks so much!
I used your pre-installed ISO and it was a piece of cake. Initially, I had the device connected over the factory cable and it wasn't recognising it, but when I swapped to a standard cable, suddenly I was able to reboot into recovery straight away. Rom mounted and installed, and I have a new tablet!
Definitely appreciate all your hard work!

That`s great I`m happy you had good success!!

[Q] KF2 Empty and not recognized on windows

So I was trying to change my son's Fire 2 over to the new Kit Kat OS, and as I was downloading the necessary files to my computer, I thought I would wipe everything, since he had managed to pretty much fill it with junk, (he's 8). I have TWRP, (2.3.3.0) installed, and used that to wipe everything, including the internal storage and the format data wipe. I have done this with my Fire 1 with no issues, but this time I ran into a problem. TWRP works fine, but now windows won't recognize the tablet. When I go to mount the usb storage to copy the os files over, windows 7 cant load the device drives, and in my device manager it shows the Amazon Kindle fire 2 with the yellow exclamation mark next to it, saying that the drivers for this device are not installed. I have the SDK installed, and I have gone through and re installed the device drivers several times, and also uninstalled the kindle from the device list in manager. Nothing is working. I have attempted fastboot, but when I do try, it gets stuck at the "press the button menu" for TWRP, and after running the fastboot -i 0x1949 getvar product command, it tells me it sees an Otter2-Prod-04.
Does anybody have any ideas or suggestions on how I can get into the usb storage so I can load the OS info? Thanks for any help.

Dead?
Well, I rebooted from TWRP and it just went black. No light when the cable is plugged in, (factory cable), no twenty second reset working, nothing. IS it safe to assume I now have a pretty paperweight, and I should be looking into getting my son another tablet?

Leave it on the charger overnight. Keep trying 20 second reboot. If you can get back into recovery you can adb sideload a rom into the device.
You've never been able to USB Mount this device from recovery.
Good luck. No reason it should be bricked....
How did you try to get into fast boot? You need a fastboot cable. This device is NOTHING LIKE the kf1.
Edit: also need to be sure exactly which kf2 you have.

I have the standard cheap Kf2, no HD, just the upgrade from the first from last year, (2012), they were selling around Christmas last year. I have tried getting it to start back up, but with no success. I don't even understand why it shut down like that. I hadn't done anything to it other than reboot, which I had done successfully several times before. As for the fastboot, I may be incorrect. I ran the adb command: fastboot -i 0x1949 getvar product in CMD, and then plugged the kindle in and booted up. It showed it was an otter4 or something like that, which I thought meant it was in fastboot. At that time I was using my S4 usb cable. I'm sure I can sort out ho to sideload a rom via adb if I can ever get it started back up again. I had thought about opening it up and unplugging the battery and then re-plugging it back it to try to reset it, but I doubt it will help. Would getting a fastboot cable possibly make it start back up? If anyone has any suggestions on how I can get this thing started up again I would greatly appreciate it. I fell like crap for bricking my kids kindle, he's 8, so it's really important to him. It'll take me several months to save up to buy another one, so if I can get it running again, that would be awesome.

Here's a bit of an oddity, and maybe this spells some hope for me yet. So I plug the KF2 into the computer with the factory cable, hold down the power button for twenty seconds, let go, and then hit the power button again, for about a second, and windows makes the usb device plugged in sound, followed by a usb rejected or not recognized sound. It repeats this over and over for about thirty seconds or so and then stops. So there is something going on with the kindle, and its not flat out dead, or at least it seems. Is this a good sign? Does this help anyone to figure out what I might need to do?

So just to be sure that I was using a fastboot cable, even though I believe that my samsung s4 cable is fastboot capable, and I'm pretty sure I am using the factory cable, (it's not marked so I can't be 100% sure), I built my own fastboot cable, via instructions on how to do so on xda. (found HERE) It's doing the same thing with windows making the usb device inserted / recognized sound, followed by the usb device error sound. I'm guessing that this is a bad thing, am I correct?

One more bit of information to add to the list. I attempted to do the fastboot mode again,and decided to watch my device manager. Whenever windows chimes off that it detects a usb device, something called OMAP 4430 pops up for about a second before disappearing when the error sound comes on. I'm going to try and get a driver for that, just to see what happens. Maybe it'll help. I doubt it, but you never know until you try...

This just keeps getting weirder and weirder. So I installed the omap driver for windows and android, and now windows recognizes the device, but only for about a second. It just keeps cycling through the usb connected sound, recognizing the omap device, and then the usb disconnected sound, as though the device were being plugged in and then unplugged about every second for roughly thirty seconds. I'm starting to think there is something seriously wrong, which bites. If anyone has any suggestions, I'm all ears.

That's a hard brick' we can't use the usboot/aboot utility to fix the device like you can on other omap devices because we need a certain signed file to fix the boot loader. Only amazon has that file and they aren't giving it out. There is a way to recover your device from a hard brick but you need to be good with a soldering iron and have a USB sdcard reader, the kind that kinda is like a flashdrive rather than the multi type readers and some really small wire. Kurohyou wrote a tutorial on how to fix it in the kf2 dev section, not sure if he ever added the part in on how to reflash the boot loader from Linux, but if you take this route and try to fix it I wouldn't mind helping.

OK, I have both a tf - micro sd card usb card reader, and a full sd card usb card reader. I'll have to go digging for them in the morning, but I think I can find them. I'm also really good with a soldering iron, (used to be a vcr / tv repair technician), It took me roughly two minutes to do the homemade factory cable. So I am game, especially since at this point I really have nothing to loose by trying. Would you mind posting a link to where the tutorial is? I'm going to go looking for it, but just in case I can't find it, a link would help. And thank you so much for this suggestion!

OK, I found the tutorial on how to wire everything up and what's needed. I'll have to go get some small wire and a better tip for my iron, but aside form that, the wiring and soldering seems simple enough. My problem is going to be dealing with linux. I know Windows backwards and forwards, but I have a pretty limited knowledge of linux, aside from a few things we did in school to cover general PC repair. I can get it up an running, which I will do tomorrow, but I may need some help sorting out what to do with it once I have the board lined up and ready to roll, which will have to wait till next week when I get back from a work trip. Do you know if kurohyou offers repairs? If it's not too expensive, I would be willing to pay for the fix.

He might repair it, he just made a solderless repair tool to repair them. But like I said I'm more than willing to help with the Linux side, I'm a PC tech myself and use Linux primarily, you can basically burn an ubuntu live CD or put it on a USB stick and boot into the entire os without having to install it, from there's its as simple as plugging the device into the PC, and seeing what device path it assigned to the kindle's emmc, and running a dd command to flash the boot loader back onto the device.

Yeah, I've ran a live usb version of unbuntu a few times, and in the past I have had the full version on my system, but I rarely ever used it, so I got rid of it. I have an extra 600 gig's of space just sitting around on my laptop, so I will install a full version, and get off my lazy rear and start learning linux. This should be a good first lesson. I can't do any of this until next week though, so I will be pm'ing you once I've gotten everythig hooked up and ready to go. Thanks again for the help.
I had a question about the repair though. I went through the discussion, and I may have just missed it, but did he ever figure out how to get the OS up and running? From what I could tell, he was still working on it, and hadn't managed to get a working rom loaded. I probably just either missed it, or didn't understand one of the post's.

I Guess I Discovered a New Form of Hard Bricking on my Device???

I was running the Developer Preview Beta 2 and noticed that my device would no longer communicate correctly with my OTG usb jump drive, I tried all the normal trouble shooting techniques and nothing worked. I than tried connecting my phone to my computer and my computer would no longer connect to my device either. I didn’t think this was a big deal so I was going to just flash back to the May factory image from my computer.
This did not work, so I did a factory reset in TWRP hoping that this would clear out the issue that was stopping the phone from usb communication. It did not fix the issue. So normally in TWRP I can always plug a flash drive into the phone through the otg and explore the files, however for some reason this was still not possible, something has happened to the device where it no longer allows incoming or outgoing usb communication. The device still charges however it is no longer recognized at all by my computer nor does the device recognize usb drives. I have all the latest USB drivers and updates needed. I uninstalled and reinstalled my drivers on my computer as well. The main issue I feel like I am having here, is that the device no longer wants to communicate with usb asides from charging, this is why it is not seeing the otg storage when I plug it in while I am in TWRP.
I am at a loss, I can boot into twrp and explore the device, this is useless as i deleted all the files on the device, TWRP will not allow a usb to be found so i cannot flash anything to the device. My computer does not see the phone so i cannot fastboot anything to the device. I have tried everything, DUECS script, skipsoft, none of them have identified a device. This is further verified by running cmd and typing in adb devices, to which the response is a blank line.
How can a device be bricked, but somehow have TWRP recovery working, along with the ability to boot the device into fastboot/the bootloader (and yes the bootloader is unlocked still)? If anyone has any ideas of how I can get this thing to be recognized by my computer please let me know.

I would try a different cable as this device is very finicky; that solved my issue of the computer not recognizing the phone.

Is it possible that your device's USB port data transfer function is damaged, but the charging portion is functional, making it a weird hardware failure?
You know, like the old days when the charge port would break or wiggle loose, and sometimes it would charge and sometimes it wouldn't, depending on the angle of the cable in the mini usb port?

That would be nice if that were the problem, but unfortunalty I do not think it is. For example, when the issues first began, before I did the factory reset on the device, windows would pop up a message that said unknown device, and failure to connect. After the factory reset in TWRP the computer gave up all together in recognizing the phone. Another sign it was likely not a hardware failure was when the device was on and i was attempting to connect the otg usb to the phone it would give me some weird options. With android P the options were, allow this device to control the usb, or allow the USB to control the USB. that made no sense to me since why would i want the the USB to have any control, it couldnt do anything its not a computer its only a storage device. However, even though I had file transfer selected in developer options, it would not allow this connection. The options were all greyed out and it would not allow the pixel to have control over the usb device.
As for USB cords I have used without fail the google issued USB cord that came with the Pixel 1 xl, It has never faile me or had any issues. It is still fully functional as I was able to use it to connect my girls note 8 to my computer for file transfers and all other things my phone is not doing anymore.
I reached out to google and explained the situation to them, after i told them I was on Dev preview beta and they verified this to be true they told me this is likely a hardware failure and offered to replace the device. I am now waiting on the new device to be sent to me, however still cant accept that i cant recover the current device with an unlocked bootloader, TWRP installed, and access to fastboot/bootloader screen. I have seriously bricked phones before as in they would not even turn on and I was able to get them back up and running, this would be my first ever device I could not recover and what makes it worse is that it actually has TWRP installed and powers on and off just fine.

Sorry for the obvious question: Do you have the latest drivers? I don't have the drivers set to the whole system (Windows), so if I don't CD into my fastboot folder, I can't do anything because the system wide drivers aren't current. Don't know if that could be your issue?
I'm too lazy to fix the PATH of my drivers ¯\_(ツ)_/¯

I had an issue similar to this. I was trying to hook up a USB c to Ethernet adapter. It worked fine on April's patch but after I flashed Mays the phone wouldn't recognize it. After I plugged it in my phone rebooted and I no longer had access to developer options and it wouldn't read any usb device. Luckily I had a TWRP backup on my device. Once I flashed the backup which was only about a week old everything worked again. I haven't tried using the adapter again. I think something in the data partition got corrupted. I tried just restoring the boot and system partition and that didn't fix it. Try doing an advance wipe and formatting the data partition. That might get you back up and going.

have we even seen a bricked device yet?

I didn't think it was possible, I still dont understand how this is happening. For the other responses above, I have all the drivers up to date, and I already formatted data, wiped everything. At this point I would like to see if there is anyway to delete TWRP recovery from the device, anything, I have no OS on the device, but for some reason still have TWRP on both A and B.
I almost dont want to give the phone back to Google because I want to figure out what happened and how to fix it, its definitely not broken/bricked like you see when someone flashes the wrong files to a device, it just has no USB connection capabilities which in-turn have rendered the device useless.
When I had Samsung phones if you bricked a device to the point it doesn't even turn on correctly you could always save it still using ODIN. Its weird that the google flagship device and software doesn't have its own proprietary flash software like Samsung, LG and HTC, we just have adb/fastboot, I feel like if we did, i may be able to get this thing started again.

have you tried using something like quickboot from the playstore to be able to get to fastboot?
I had a similar thing happen a few weeks ago on oreo. PC wouldn't 'see' the phone, but it would charge very slowly.
I installed quickboot, booted to fastboot and was able to flash the factory image

I can't access the play store on the device in it's state. I do have access to fastboot. I can boot the phone to fastboot, and into TWRP, only problem is the phone doesn't communicate with the computer in either state. If the pixel had a SD card slot I would just load up a recovery but unfortunately we don't have that luxury

What cable are you using to connect to the PC? Is it USB c to USB c?

The cable is not the issue, I confirmed this by testing all my cables with the new device that I just received for my warranty exchange. I also tried my luck with Linux, after a complicated installation on my computer I was able to have Linux actually detect the device (partially) when the device was plugged in at splash screen I got nothing, at fastboot/bootloader screen nothing, but once the phone booted into TWRP it came up as AOSP device, when I attempted clicking on the AOSP device being detected by Linux an error message popped up telling me mtp or midi error, not sure for sure what one it said. Either way I couldn't connect for any transfer of information, I tried adb sideload and that failed as well.
This has been an experience for the memory books, glad that old device is gone and I'm back up and running on a working phone. No more beta testing for me, I'll be ready for Android P when they get it out of beta, I don't have the time or patience to deal with any more warranty exchanges.
