[Q] USB Boot Short Trick - Kindle Fire Q&A, Help & Troubleshooting

I have a KF 1 which is bricked, can't power on, no led. Win recognizes it as OMAP4430 temporally.
After some research, seems Firekit is a good try. Everything is documented amazing, only part I am not quite sure is "USB Short"
I understand it is about using a wire to connect that particular pin in the picture, but what the other end should touch? If there is a picture would be great.

Short pin to metal frame of the Kindle

I tried that, but always blocked at step two, Fix partition, wait for device.
Any suggestion? The Firekit, fix partition command. Does that mean my kindle is brick completely?
Thanks

[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.

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?

[Q] Bricked Kindle Fire- Stuck on FFF, device not recognized by anything.

Alright folks, I would like to start off with a little introduction:
I'm extremely new to the rooting scene, i've been jailbreaking iphones and ipods since day one. That being said, I probably should have spent more time researching this technique before I went through with it.
Fast forward to today:
I tried rooting my device awhile back, wasn't a 100% successful and I really didn't have the time to work it out. I did have FFF installed and the next window (which i'm not exactly sure what it's called, which allowed me to boot in various moods and such)
Earlier today I got stuck in a boot loop, where my kindle would turn off as soon as i restarted it, and after i selected normal boot mode. I decided it would be a good idea to try a different boot option, so i tried the FF boot, which completely ruined my day.
My current situation is as follows:
I'm currently stuck on the first FFF screen (yellow triangle, with the green light on), i can do nothing else from that screen except hard (cold) reboots. When i plug my kindle in (Mac, windows 7, windows XP), the device is not recognized and i get zero response. I've tried a decent amount of suggestions on this forum, including Kindle fire unbrick (Which can somehow see that there adb is installed, but the bootmode is unknown)
Help out of this current situation would be wonderful. I'm really in a jam here.
Sounds like you are stuck in fastboot and you might have a dead battery too.
You should read this...

Thanks for the reply,
I read pieces of the first one before I posted on this thread. The KF was 100% charged and i only used it for about 15mins before the whole crashing problem occurred, so i highly doubt it's a low battery issue.
The screen that i'm stuck on is actually the recovery screen. After reading the article in it's entirety, i'm still not exactly sure what to do. My problem is that i cannot get my kindle fire to be recognized as any type of USB device on any type of computer. Wouldn't that issue need to be addressed before i can go about doing anything else? Or will drivers see what my computer think is not there?

What do you mean by recovery screen? Because your first post said FFF and that's your bootloader. If the yellow triangle boot logo comes up and that's all that the display does (doesn't go black and redisplay the boot logo), then it's in fastboot mode. Windows should give you an indication that it's connecting with a series of 2 connection beeps (low->high tone) without a following set of disconnect beeps (high->low tone). The device manager will show something new in the list (this is covered in post #2 in the first URL I pasted for you).
Yes, you need to get something to get recognized by your computer then you need to install the proper drivers for it. Look at post #2 again, and see if you can figure out what device is appearing in the list and get the drivers loaded for it. If you get absolutely nothing, there's something wrong with the bootloader, your USB cable, USB port, or computer in general and it's a bigger problem.
If nothing happens on your computer, find another one and hook it up there. You might also look at this...
http://forum.xda-developers.com/showthread.php?t=1430038
and see if Linux can help you.
I'm sorry, I was mistaken. I am stuck in Fastboot mode, The one with the yellow triangle. I get zero indication from Windows device manager list, or beeps (same on my mac). I have tried 3 different cables, so i highly doubt that's the problem either.
My next step is the linux distro, which i will get back to you with when I get everything installed. My only concern is that the linux distribution isn't going to recognize the USB either (seeing as 2 other operating systems haven't) and that there's something inherently wrong with my kindle. In which case i'm ****ed? or is there any chance that amazon will take it back?

Windows will be the only one that of the three that will beep at you. There's a better chance of you getting something done with Linux, but it's starting to sound like a bootloader problem to me. There's another user with a similar problem to yours and he's basically where you are now. Both of you might have to open up the case and get it to USB boot mode where you can upload a bootloader to it through USB. Try Firekit and see if it gets anywhere.

[Q] No power after Usbboot shorting trick

While attempting to unbrick my kindle using the Linux usbboot short trick and not getting anything detected in firekit and soupkit nor win7 for that matter, my little green power light now is always off. No power via battery and worse not even usb cable to pc even lightsup. Is this totally useless, now?
Probably not. What exactly were you doing when this happened? Please be as detailed as possible.
"That's a special kind of stupid. The kind that makes me laugh."
I had cm7 on for a long time with usb mass storage working and adb etc. Then I went with an early ver. of cm9 and found no usb connection or sd mount was possible. Months later i gave to my gf who wanted photos on it. But windows has not detected it. So I tried to update with cm10 and it was advised to update my twrp to 2.2.2.1. But upon using this new version of twrp I noticed I could only restore a backup I made. That worked. But the flashing of the cm10 rom did not, The touch screen was not responding at all, there.I rebooted into twrp and retried to flash the cm10 with still no screen response so I pressed reboot and saw "bootloader" and pressed it instead of reboot or sysem or plain shutdown. Thus my brick. I read much and guess i was stuck in fastboot mode and w/o any adb detection by windows 7 went with Linux usbboot shorting trick. Made the usb stick boot up to ubuntu and tried firekit and soupkit to no avail. Always showed Waiting for device!. Of course the back was off and pin shorted on mobo. Minutes later I notice all lights of kindle fire are out. No more Triangle or anything! Pc usb cable does not power it on nor does my battery charger in ac or solo w/battery. This is what I can recall from last 3 days.

Ok, the reason I ask...
Your device is either in USBboot or you didn't install a bootloader properly. At first glance it seems it's the latter. In Firekit, select "usb_install_fff_twrp". If it just sits at "waiting for OMAP4 device" you'll need to use the shorting trick to detect the device and get the bootloader installed properly. Afterwards, if I were you, I would use recovery to install the latest version of FFF before rebooting.

No, you misunderstood. The device already powers up (even though it doesn't seem like it), it just doesn't have a working bootloader. Without a working bootloader, the only way you can communicate with the device is to put it in USBboot.
There's a possibility it is already in USBboot (unlikely) and Firekit will send commands anyway. Otherwise, you need to use the shorting trick to temporarily put it in USBboot long enough for Firekit to work.

On another route, What if I buy a new KF 1st Gen. from a retail store and put this bricked one in the new box with cords, papers etc. and return it within the full refund time would I stand a chance at getting refunded? Also since it won't light up could I claim it is simply bad hardware section of the unit? Plus would it eventually get torn down ,Amazon..where they might see it was rooted and registered by me?
I have a better idea. Why don't you take some personal responsibility for a problem YOU created and either fix it yourself, send it to someone who can, or suck it up and cut your losses?
I could go on all day about the moral, let alone the practical, implications of how such a decision will impact the community as a whole, but we both know that would be a complete waste of my time.
Do as previously suggested or not, but don't complain when it becomes increasingly harder to make a device, one that you've spent your hard earned money on, your own.

[Q] Bricked Kindle Fire - not starting (black display - no logo), not charging

This is my first post on the forum so i say hello everyone! First sorry for my English I have a bricked Kindle Fire 2 After root and installing TWRP Recovery my Kindle flashlight was shinging orange color and it was suspended. I turn it off and now i can't charge it and i can't turn it on. The flashlight is dark, not shining. I try Kindle Unbrick Utility, Firekit Live USB but my KF is still dead. Can someone help my with my problem? What should I do?
Does your computer recognise the device? I mean at all? If not then more then likely your logicboard/motherboard on the kf2 might be dead which will make your kf2 as useful as a paper weight ( just telling the truth)

Since the bootloader isn't working, there is no access to fastboot to reinstall it. In order to do that now, the bootloader must be installed to the device using the OMAP4boot tool, 'usbboot' (Firekit uses this), to communicate with the device using low level usb commands (that is, assuming it's a KF1). In order for usbboot to work, the device must first be put into usbboot mode (4003). According to Pokey9000, sometimes when there is corruption of the bootloader, the device automatically gets dropped into usbboot and Firekit work without a hitch. However, most of the time this is not the case and the device must be forced into usbboot mode using the shorting trick.
I won't go into any more detail about how to make it all work without first knowing whether you have a KF1 or a KF2.
BTW, just because your device doesn't show anything on the display, doesn't mean it's not on

HI Soupmagnet
Well i'm in the same situation with my KF2 - so if you have any input to get it up and running again - please share...
I got the OMAP4BOOT working - but any attempt gives me a "unexpected 2nd stage response"
Really need some input

I have done a lot of reading. But I still not sure if fixing my KF2 i possible.
Some threads says they got the 2nd bootloader and then not really the right one course of the signed Amazon Keys is still unknown.
Some threads says that KF7 HD is the same HW and that solution can be used, but that solution doesn't include OMAP drivers.
So is the conclusion still that if you get a OMAP device you are f•••ked.?

[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.
