[Q] Help installing TWRP (won't start)

As a disclaimer, I've searched for this question, but have only found when the question is asked as a much broader topic and goes unanswered.
That being said, I can't seem to get TWRP 2.0 installed through using "fastboot boot", the Kindle Fire Utility, or the technique using dd to rewrite the contents of the parttitions.
The closest I've come is getting FIREFIREFIRE to start up using the "dd" technique, but TWRP still will not start when I hit the power button for recovery. And yes, I did use "dd" on the TWRP image file as well.
Also, I even tried using fastboot to flash u-boot.bin onto the bootloader partition, and twrp onto the recovery partition. Still, I can get to the yellow, but no further into starting TWRP.
Any help would be appreciated. At current time, I have the stock bootloader and recovery partitions on the Fire and it is rooted.
Thanks.

maybe your in fastboot mode and hopefully your drivers are installed correctly you can use:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
or
fastboot -i 0x18d1 oem idme bootmode 4000
fastboot -i 0x18d1 reboot
or
fastboot oem idme bootmode 4000
fastboot reboot
this should bring you to normal bootmode

I've tried that in case there was an issue. In fact, if I don't press the power button during the yellow triangle, the Kindle Fire OS will start as normal after 10-15 seconds. So, it looks like the bootloader is working right and I'm in the correct bootmode. But, if I hold down the power on the yellow triangle (which is supposed to start TWRP), I just get stuck and nothing starts.
That being said, I think I'm in the correct bootmode.

if i don't remember wrong there is an issue with installing twrp with dd
i think you could retry the installation or simply use KFU (but don't use the drivers of kfu if you have working ones)

Thanks.. I'll give it another shot tonight, and then.

when the device starts and the Triangle appears, are you just pressing the power button once? or are you pressing it until it turns orange?
I have to press it a few times before it changes color to orange and then just let it alone. A long press doesn't work for me.

I can get it to turn orange. I think the long press worked for me on that one. Though, I do know I did the multiple presses as well and didn't get any further.
Is it possible that it might be goofed up because I used SuperOneClick for the original root on 6.2 instead of KFU?

not possible - had the same - rooted with superoneclick on 6.2 then updated
i think your twrp install failed - would retry

I finally figured out my problem. For whatever reason (which is still unknown to me), the Kindle Fire Utility was not able to properly download the twrp.img. The file that was downloaded was 8K (which I'm guessing was some sort of error web page). Anyway, I went straight to teamw.in and downloaded the latest version that clocked in at around 10MB, installed it via the "fastboot -i 0x1949 boot twrp.img" command and all is well now.
If anybody is having similar problems, you might want to check the size of the twrp.img file. 10M = good, 8K = bad.

It turns orange the second it starts booting recovery. That's when you should let go. Holding the power button for ~30 seconds for any reason is a hard signal to the PMIC chip to power off.

good that it works again ...

kf format

Ok, still have prob with kf...I think all i have on here is TWRP, so with some help from ppl on here i now have the KINDLE FIRE on screen. Still cant get anything else. So is there any way i could format & load any other program on here. I dont care about kindle fire i was going to root it again anyways. Please help .....

as long as you don't get adb working there is'nt much you can do
allready tried firekit ?

I see i tried the things you said well i think i did them right. iam not sure...
I done so much. I just dont know why it wornt pick it up, i can get it to see it on one computer but it has the yellow mark on it & then the other computer dont see it as kindle just as the phone. so even if it format it still wont help (its not like a computer you can load a program on it)

what is it when they get a cable when they brick them?

that is a factory cable - it forces the kf to fastboot mode
that will not help in your case because you can get to fastboot mode
and fastboot commands are working
you can't get adb commands to work - this is the problem !
firekit is'nt working eighter ?

ok i see i dont understand i had it on both of my compter and they work fine because i rooted the kindle on these. ther must be something with the way its loading on here. maybe i can try the other compter i have....

you'r talking about firekit ? other computer is a good choice anyway
did you allready read this one :
http://forum.xda-developers.com/showthread.php?t=1552547
it clears up how the kf is working

someone said something about turning off debuging on the computer what do you think?

???
don't know such a option on a computer/win system

Well someone said to mount and download Kindle OS 6.3 and it sould let me boot up. I loaded it backed it up installed it did averything i was told to......but still no work. it still boots up to kindle fire on screen but wont do anything else.
So anybody got anything else i can try?

you where able to copy a new rom to the kf ?
if so that is a great progress - would recommend this one:
http://www.mediafire.com/?8h485buu55cawc5
to clean up partitioning/restore factory partitioning you can use this, just use the newer rom linked above:
http://forum.xda-developers.com/showpost.php?p=22433402&postcount=4
btw first boot after flashing can need up to half an hour

Hi, yes i was able to get the 6.3 update on here by doing mount and sending it as a drive F and it seam to be there. you say it mite take a long time to boot up with this one i wounder it its takes a long time with what i have on there now. maybe it just didnt have time, i did leave it for about 45 min.

This is the one i loaded on here already is this the same one? http://forum.xda-developers.com/showthread.php?t=1569298
the other download you have here sould it be done after the frist or before, I can do a lot of thing on here but some iam not sure if iam doing them the right way, i think that why it didnt get backup the frist time....

that is realy too long - would try to restore factory partitioning as suggested in my last post:
1. set bootmode to fastboot -> fastboot oem idme bootmode 4002
2a. if you'r not in fastboot now pwr off / on the kf - the command should resume and finish - a second pwr off / on should boot fastboot
2b. boot to fastboot -> fastboot reboot
3. download fff 1.2 and extract to your tools folder
4. update fff -> fastboot -i 0x1949 flash bootloader u-boot.bin
5. reboot -> fastboot reboot
6. restore factory partitioning -> fastboot oem format
7. set bootmode to recovery -> fastboot oem idme bootmode 5001
8. boot to recovery -> fastboot reboot
9. flash new rom in recovery -> look at the op of the rom what and when to purge something
10. set bootmode to normal -> fastboot oem idme bootmode 4000
11. pwr off / on the kf - the command should resume and finish - a second pwr off / on should boot up the new system
btw yes it is this one - i recommend and linked in the unsecure version

ok got this thing to this point and dont want to mess up but not sure what to do with bootmode, fastboot not sure where i need to go to get into them

[Q] Kindle Fire 6.3 in FFF Recovery Loop, Not Detected -- Need Help [Linux]

Hey guys,
I'm sorry I couldn't figure out what to do next simply by searching your forum, so I will try to be both as brief and as descriptive as possible.
I started here (http://forum.xda-developers.com/showthread.php?t=1568340) trying to root my fiancee's KF 6.3. I didn't feel comfortable using KFU or similar because those programs are built for Windows and I am using Linux. The Kindle Fire seems to be stuck in a recovery loop. When plugged into USB (using the cable that's actually for my LG Optimus phone), it boots to FireFireFire (yellow triangle) then reboots constantly. At no point is it accessible via adb devices or fastboot, and it doesn't show up under lsusb, which would be the equivalent to not showing up in Device Manager in Windows. (The driver should be fine because all of this was working fine originally when I started the process.)
So I guess my question is what now? I've read a few things about needing a "factory cable" which may set it back into fastboot mode, and I'm pretty sure I could get going again from there. Is that what I need to do? TIA for any help.
PS - I've successfully rooted my LG Optimus S and flashed custom ROMs, so I'm not totally inexperienced. I use Arch Linux and I'm comfortable on the command line. If you have a solution for Windows, I *might* be able to translate it into Linux speak, so don't hold back. Same goes for Ubuntu/Debian - those are totally different than Arch Linux, but I might "get it" enough to translate it.
PPS - I have intentionally omitted information relating to what I was doing when I caused this for brevity, but I would be happy to discuss what steps I took in following the above linked thread if some guru believes it's relevant or someone wants to know.

A factory cable is a last resort kind of thing so I wouldn't jump the gun quite yet, although it doesn't hurt to have one in the first place.
It would be helpful to know which step in the rooting process things went awry. The constant rebooting/restarting isn't typical. Did you make sure you had enough battery before trying to root?
FIREFIREFIRE loads in a temporary fastboot and with the version you are using it lasts for about ten seconds (before the green light goes dim). You can issue fastboot commands during this time without the need of a factory cable.
See if you can get...
fastboot devices
...to be recognized during this time.

If you get stuck at a screen with a yellow triangle, run: fastboot -i 0x1949 oem idme bootmode 4000 If your device is always booting TWRP run: adb shell "idme bootmode 4000" If you still can't get out of booting TWRP, first run: adb shell "idme bootmode 4002" reboot your device, then run: adb shell "idme bootmode 4000" reboot again and you should be out of your bootloop.

OK, let's start with that.
From the thread I linked in the first post:
Your device will now boot into twrp recovery, and flash the firefirefire bootlaoder. When done it will prompt you to reboot. Upon reboot you will get stuck on the "yellow triangle" screen of firefire fire.

That was not my experience. My device loaded TWRP but just sat there on its home screen without prompting me to reboot. I used adb reboot recovery to see if it had indeed flashed FFF but was simply not prompting me to reboot, and it had not. So I used instructions from elsewhere (http://forum.xda-developers.com/showthread.php?t=1369405) to flash FFF at this point myself:
Howto flash by hand
Get into fastboot mode somehow. Having and older FFF from the TWRP installer is a good start. Currently KFU or fbmode is the easiest
flash with "fastboot -i 0x1949 flash bootloader u-boot.bin" (take out "-i 0x1949" if FFF is already installed)
disable fastboot: "fastboot -i 0x1949 oem idme bootmode 4000"
reboot: "fastboot -i 0x1949 reboot"

There were a couple of weird issues with this but the process seemed to go smoothly. However, when I rebooted (the last command) is when I discovered I was stuck in a recovery loop, and the last time I was able to see the device normally via adb devices/lsusb/dmesg.
I guess it may have been the battery because I've since let it fully charge (this is the first time I've looked at it in days) and now it's not in a recovery loop but stably sitting at the "yellow triangle". There is also now an entry for it in lsusb:
Code:
Bus 002 Device 008: ID 18d1:0100 Google Inc.
fastboot devices gives me something like "no permissions fastboot" but I have no idea what that means because I've never seen its normal output.
EDIT: I should note that I do notice the device ID now seems to register as 0x18d1 rather than 0x1949, but I'm not entirely sure what to do about that. I copied my udev rules but changed '1949' to '18d1' and 'Lab126' to 'Google Inc' but I don't even know if that was a sensible move because I've never really done much with udev rules.

I think the problem here is the he can't get past the bootloader and stuck in an ACTUAL bootloop. In which case, adb commands are useless.
One thing that could be causing problems is the USB cable being used. If the device only experiences these symptoms when plugged in then I would say that's most likely the case.

Installing TWRP 2.0.0 is different than installing TWRP 2.1.0. I think the instructions on the TWRP site is for the old version, but they link the new one.

Your OP sounds suspiciously like a dead battery, but you say you've corrected that. You might want to connect to your OEM charger for a while anyway and see if that helps
Also, in my experience, fastboot on linux required elevated privileges. Try running it as root.

I've done the Arch Linux equivalents of all of that, and I'm set up with udev rules per our wiki here: https://wiki.archlinux.org/index.php/Android#Adding_udev_Rules
I'm pretty sure the USB cable I'm using might actually be the issue because it was fine straight off the OEM charger, and I even momentarily got a correct reading with fastboot devices (as root), but now I'm back to almost like earlier. The yellow triangle screen is still "stuck"/stable, but I can't find it on adb/fastboot devices or lsusb.

This is fine. It just indicates you are running the FFF bootloader... pokey9000 changed the VID to a value fastboot recognizes by default instead of the custom vendor ID (1949) that Amazon uses in the stock bootloader. With the FFF bootloader, you can drop the "-i 0x1949" part of the fastboot command.

Have you tried setting the bootmode to normal and rebooting?
fastboot oem idme bootmode 4000
fastboot reboot
Like I said before, it would probably be best for you to try this as root.
EDIT: It's also possible your system is broken and the KF can't complete its boot process. When you start up the device, the boot logo will first come up. Does the display go black after that and come back with a dimmer yellow triangle logo? Because if it's doing that, it's not in fastboot any more.

Yay! I played around and got my udev rules working, and I got a reading on (sudo) fastboot devices, so I was finally able to set the bootmode to 4000 and reboot. Everything seems to be back to normal now. The Kindle appears to be working fine though not rooted.
Please let me know:
if there is anything else I should know to make sure the KF is normal
if there is any additional info I should post to benefit other users who might have this same problem
or if I should mark this thread SOLVED/RESOLVED or equivalent and how to do so.

if your fastboot ever stucks in waiting for device mode and you are on linux
try once with either root user or using sudo command.
thats one of the thing people forget most of the time and get stuck there.

[GUIDE] Fastboot Mode

As mentioned in the guide, Kindle Fire For Beginners (KFFB), fastboot is the key to fixing all software related problems on the Kindle Fire. Regardless of the actual bricking circumstances, the Kindle Fire can be unbricked if the device can be put into fastboot mode. Even in the worst situation, the unbricking steps boil down to...
Get to fastboot mode
Use fastboot flash to install a recovery
Use recovery to flash a bootloader and ROM
Although these points are covered in KFFB, it can be difficult to discern the actual procedures for putting the device into fastboot mode and recognize when it has been enabled. This guide is a more concise presentation, but it assumes at least some basic knowledge discussed in KFFB. If you are unfamiliar with that guide, please read that one first.
WARNING: Multiple users have reported problems with fastboot when using a USB 3.0 port. This is probably a bug in the fastboot program. Move the cable to a USB 2.0 port before using fastboot.
Identifying The Bootloader
Because the bootloader is responsible for enabling fastboot mode, one must be loaded and working properly to issue fastboot commands to the Kindle Fire. To determine which bootloader is booting the device, take note of the bootlogo on the display when it first powers up.
Stock Bootloader - white and orange "kindle fire" logo
FireFireFire (versions 0.9 to 1.2) - yellow triangle with flames
FireFireFire (version 1.3) - white and orange "kindle fire" logo with green android
FireFireFire (version 1.4) - white and blue "kindle fire" logo
Recognizing fastboot mode
The Display - As the bootloader loads up on the device, one of the previously mentioned bootlogos will appear on the display. With fastboot mode enabled, that bootlogo will be persistent and remain bright on the display. If the display blacks out and redisplays the bootlogo with the backlight slightly dimmed, the bootloader has bypassed fastboot mode and moved on in the boot process.
The bootlogo on the display is the easiest way to see whether or not the device is putting itself into fastboot mode. Again, when the device is in fastboot mode, the bootlogo will appear on the display upon start up, never black out, and remain bright on the screen.
The Device Manager - In the Windows Device Manager, "Android Phone -> Android ADB Interface" will appear in the list when the device drivers have loaded properly. If "Other devices -> kindle" (with 'k' in lower case) appears in the list instead, the proper device drivers have not been loaded and the device drivers must be reinstalled.
Hardware IDs - Also in the Windows Device Manager, right-click on whatever interface name appears for the connected device and select "Properties" from the contextual menu. In the window that appears, select "Hardware IDs" from the drop-down menu. When the device is in fastboot mode, one of the following sets of IDs will appear in that window.
Stock Bootloader
USB\VID_1949&PID_0006&REV_0100
USB\VID_1949&PID_0006​
FireFireFire Bootloader
USB\VID_18D1&PID_0100&REV_0100
USB\VID_18D1&PID_0100​
Windows identifies each USB device by these three numbers, the VID, PID and REV. Only these two sets of hardware identification numbers will appear when the Kindle Fire's bootloader is running. If the numbers differ at all, the bootloader no longer controls the device and therefore not in fastboot mode.
Linux users can use "lsusb -v" to get a list of all connected USB devices. The corresponding IDs are idVendor, idProduct and bcdDevice. Mac OS X users can use "system_profiler SPUSBDataType" and those IDs will be listed as Vendor ID, Product ID and Version in the list. The numbers are formatted slightly different than their Windows counterparts, but it's straightforward to determine what they are.
Methods for Enabling Fastboot Mode
Realistically, there are 3 potential methods of enabling fastboot mode on a working bootloader. There is a 4th method, but it should only be considered as a last ditch effort because the case must be opened for access to the motherboard. Let's cover the first 3 methods...
Factory cable - Using a factory cable is the most straightforward method of enabling fastboot mode on the Kindle Fire and it will work with any bootloader. With the device off, plug the cable into the Kindle Fire, then the computer and the device will boot up directly into fastboot mode. No other user intervention is required.
Temporary fastboot mode - The FireFirefire custom bootloader temporarily enables fastboot mode for a short amount of time. Issuing a fastboot command like...
Code:
fastboot getvar product
to the device during this time will stop the fastboot countdown and enable fastboot mode indefinitely. If the device displays a plain white and orange "kindle fire" logo, the stock bootloader is installed. The stock bootloader does not enable fastboot temporarily, so another method must be used.
Bootmode setting - The Kindle Fire has a bootmode setting that indicates to the bootloader how to proceed in its booting process. One of these bootmodes (4002) will tell the bootloader to enable fastboot mode. The bootmode setting is recognized by all bootloaders, so even the stock bootloader will go into fastboot mode when the bootmode is set to 4002. The only place this feature is likely to be used is from the system software, but there's a catch. The system must be able to provide access to a shell prompt.
For an unrooted stock device, use pokey9000's fbmode.
For a rooted stock device...
Code:
adb shell su -c 'idme bootmode 4002'
For a ROM with built-in root privileges...
Code:
adb shell idme bootmode 4002
If an error message similar to...
exec '/system/bin/sh' failed: No such file or directory (2)​appears when attempting to any of the above methods, the system cannot provide shell access. Consequently, the system will not be able to change the bootmode in this manner.
Making the decision
Then the choice of which method to use in order to enable fastboot is simple:
Do you have a factory cable available?
Does the device have a bootloader with temporary fastboot?
Can the device be booted into a system that can grant shell access?
With a working bootloader, the first question to which you can answer in the affirmative is your best choice. If the device does not have a working bootloader or you've answered "no" to all of the above, there's only one option remaining to you. Remove the back cover of the Kindle Fire to get access to the motherboard, short an exposed connection to the metal frame and employ pokey9000's Firekit. This procedure will set the device into USB bootmode and Livekit can upload a fastboot mode enabled bootloader through USB.
Getting out of fastboot mode
To get out of fastboot mode, make sure the bootmode is set to something other than 4002 and reboot the device. The examples below will set the bootmode to normal and reboot the device.
With the stock bootloader...
Code:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
With the FFF bootloader...
Code:
fastboot oem idme bootmode 4000
fastboot reboot
If a factory cable was used to enable fastboot mode, it must be disconnected before the bootloader loads again or it will go back into fastboot mode. You can quickly yank the cable after the reboot command has been issued, but it's probably safer to press and hold the power button for around 20 seconds to turn off the device, disconnect the cable, and turn it back on.
Using Fastboot commands and other information
There are many guides related to fastboot. Here are just a handful of starting points...
Installing Windows device drivers for fastboot
A list of fastboot commands
Using fastboot to install TWRP (See "Installing a recovery and custom bootloader")

@kinfauns, can a broken bootloader boot into fastboot with a factory cable?

No. The bootloader is what enables fastboot mode. The factory cable does not help the situation if the device does not have a working bootloader. Under these circumstances, you must open the case, use the "shorting trick" and upload a bootloader into memory using usbboot.

Thanks, so an advice for normal user is not to mess around with bootloader and double check md5 before flash it.

I've rearranged the sections in this guide in a more logical order, clarified a few points and cleaned it up. I've also added a list of hardware IDs that should be fairly foolproof to see whether or not the KF is actually in fastboot mode. A section on how to get out of fastboot mode has also been added.

Excellent guide! Thanks.

Thank you so much for this. I have been reading up on fast boot recently and it is a huge help to have it spelled out in one place.

Interesting guide. Problem is that it probably doesn't work on newer fires.
Let me explain: So I had my Kindle Fire replaced and following this guide got into fastboot mode (through factory cable in my case). Problem is that once I'm there neither Windows nor Linux recognizes my device. This must be an ailment of newer KFs because the old ones -I remember clearly- could well be recognized while in FB mode.
Any recommendations?
edit: I can't get out (FB mode) right now so I would *really* appreciate any help.

I have nothing to offer in your immediate situation, but do not use any technique from these forums if you have a KF2.

- You are in the wrong forum if you have a 2nd generation KF, but fastboot mode is definitely accessible on them and commands can be issued.
- This guide was written for the original KF, so a great deal of the information here is does not apply to the 2nd generation KF. The custom bootloaders will not work, the hardware ID values are different, the bootmode values are different.
- If you can't get your computer to recognize the device in fastboot mode, it's a problem with the device drivers on Windows or incorrect permissions to access the device on Linux. Both of these are probably caused by the different hardware ID values. You'll need to alter the INF file to match them for Windows and redo your udev rules on Linux. This guide includes the procedure for finding the hardware ID values, you'll have to look at some other guides for applying them.
- If you used the factory cable to enter fastboot mode, all you need to do is force the device off, disconnect the factory cable and reboot. If you changed the bootmode on a 2nd generation device, you're on your own. The various bootmode values have changed and I don't know what the proper ones are to get it booting normally again.

I don't think I'm on 2nd Gen KF, I got mine pretty much by replacing my dying KF (1st gen), so I can't see how I could end up with 2nd gen.
But say I am as you correctly pointed out Fastboot should had worked, problem is that it never did.
The reason that I'm stuck (on FB) right now is that I had though that it was because of the cable why I was unable to get properly into Fastboot, so I used a dif. method.
edit: The hardware ID is:
USB\VID_1949&PID_0006&REV_0100
USB\VID_1949&PID_0006
So I'm definately on first gen, so back to my orginal question why the heck my KF is not recognized (in either Windows or Linux, I've tried both multiple times)?
edit2: Well, to make matters worse upon booting my Fire is recognized (so the drivers are correct) but when I'm trying to do anything, anything at all, the device does not respond. So I reconnect the usb cable and this time around I get "unknown device" in Windows and in Linux -well- I pretty much get nothing, as if the device was never there. I fear that my replacement is not exactly in working order, unless there's something major I'm missing. I literally did nothing else apart from trying to get into FB since I got the device out of its package...

Yes, that is the original KF. Almost every one of these cases is related to device drivers on Windows. I suggest you read/follow this...
http://forum.xda-developers.com/showpost.php?p=23747671&postcount=2
If that doesn't help, you should try Linux which is not as temperamental when it comes to fastboot mode. You might want to try soupkit to get your Linux environment configured properly. Whatever route you choose, you need to try rebooting the KF at least once in a while. Your computer and KF need to see each other the moment the KF goes into fastboot mode. If that doesn't happen, nothing you do after that will matter.
If you continue to have problems, post in the Q&A forum. Someone hanging out there will help you.

Naturally I did those before posting here (if you read my post you'd see that I'm talking about Linux), I've posted about Windows so that I'd make my situation more relevant to most people's experiences with those things...
Obviously my situation is out of the ordinary (or else -again- I woudln't post here). Anyway, I'd try the Q&A hoping that I'd find answers there, but I insist my problem is most probably hardware (if it was SW I would had found a solution until now, me thinks).

@ kinfauns,
Do you have some way of posting a video of what Fastboot mode looks like when launched via a Factory Cable please? I have had many people tell me its booting up but not into Fastboot mode, however I have been under the impression that the KF splash screen logo means its in Fastboot mode already.
A few weeks ago someone told me his device was not passing the initial splash screen then a few days later he tells me it was his computer at fault and that it was already in Fastboot mode and that my Factory Cable worked perfectly for him. Now today another individual is telling me the exact same thing, its not passing the initial splash screen and that Fastboot on his computer does not see the device. I have been under the impression that if Fastboot does not communicate with the KF, then the computer/drivers etc is possibly at fault.
So, I am wondering what the KF's Fastboot mode screen looks like as I have never personally seen it, only has it been described to me as the KF logo screen. lol
Thanks man...

That would be a pretty boring video.
This is what I would suggest people do with their factory cable...
1) Shut down the Kindle Fire completely (press/hold the power button for ~20 seconds if necessary).
2) Plug the factory cable into the Kindle Fire.
3) Plug the other end into the computer.
4) Watch the display.
One of the following should happen...
a) The initial bootlogo never appears on the display.
b) The initial bootlogo comes up at full brightness on the display, then dims or blacks out completely.
c) The initial bootlogo comes up at full brightness on the display and remains that way.
and here's what that probably means...
a) The bootloader is missing or not working properly. The factory cable won't help here. See Firekit, Soupkit, and usbboot.
b) This shouldn't happen with a factory cable, so it's the only case where you need to worry about a faulty factory cable.
c) The Kindle Fire is in fastboot mode. That's all that's supposed to happen on the display (for a 1st generation Kindle Fire).
All of the above are completely independent of whether or not the computer is communicating properly with the KF. The cable by itself will tell the bootloader to go into fastboot mode when it powers up. So, if it's "not passing the initial splash screen" with the factory cable, that means the cable is doing its job. The issue of the computer not being able to see the KF once it's been put into fastboot mode is a device driver problem 99% of the time. That has nothing to do with the factory cable.
On a side note, the 7" Kindle Fire HD has a distinctive fastboot logo that comes up when it goes into fastboot mode. I'm guessing the KF2 also has this feature, but I haven't seen any confirmation of it.

Wow, thanks for the detailed reply. This should help a LOT to narrow down the problems that a very small few of Factory Cable users have had...
As always, thanks again man... :good:

kinfauns said:
No. The bootloader is what enables fastboot mode. The factory cable does not help the situation if the device does not have a working bootloader. Under these circumstances, you must open the case, use the "shorting trick" and upload a bootloader into memory using usbboot.

In the OP is a link to pokey9000's Firekit post. It has the necessary software attached and contains details for the process. You'll need to use Linux. If you don't have a Linux box readily available, Soupkit might be the least painful way to get there. You can find Soupkit in the Development subforum.

kinfauns said:
As mentioned in the guide, Kindle Fire For Beginners (KFFB), fastboot is the key to fixing all software related problems on the Kindle Fire. Regardless of the actual bricking circumstances, the Kindle Fire can be unbricked if the device can be put into fastboot mode. Even in the worst situation, the unbricking steps boil down to...
Get to fastboot mode
Use fastboot flash to install a recovery
Use recovery to flash a bootloader and ROM
Although these points are covered in KFFB, it can be difficult to discern the actual procedures for putting the device into fastboot mode and recognize when it has been enabled. This guide is a more concise presentation, but it assumes at least some basic knowledge discussed in KFFB. If you are unfamiliar with that guide, please read that one first.
WARNING: Multiple users have reported problems with fastboot when using a USB 3.0 port. This is probably a bug in the fastboot program. Move the cable to a USB 2.0 port before using fastboot.
Identifying The Bootloader
Because the bootloader is responsible for enabling fastboot mode, one must be loaded and working properly to issue fastboot commands to the Kindle Fire. To determine which bootloader is booting the device, take note of the bootlogo on the display when it first powers up.
Stock Bootloader - white and orange "kindle fire" logo
FireFireFire (versions 0.9 to 1.2) - yellow triangle with flames
FireFireFire (version 1.3) - white and orange "kindle fire" logo with green android
FireFireFire (version 1.4) - white and blue "kindle fire" logo
Recognizing fastboot mode
The Display - As the bootloader loads up on the device, one of the previously mentioned bootlogos will appear on the display. With fastboot mode enabled, that bootlogo will be persistent and remain bright on the display. If the display blacks out and redisplays the bootlogo with the backlight slightly dimmed, the bootloader has bypassed fastboot mode and moved on in the boot process.
The bootlogo on the display is the easiest way to see whether or not the device is putting itself into fastboot mode. Again, when the device is in fastboot mode, the bootlogo will appear on the display upon start up, never black out, and remain bright on the screen.
The Device Manager - In the Windows Device Manager, "Android Phone -> Android ADB Interface" will appear in the list when the device drivers have loaded properly. If "Other devices -> kindle" (with 'k' in lower case) appears in the list instead, the proper device drivers have not been loaded and the device drivers must be reinstalled.
Hardware IDs - Also in the Windows Device Manager, right-click on whatever interface name appears for the connected device and select "Properties" from the contextual menu. In the window that appears, select "Hardware IDs" from the drop-down menu. When the device is in fastboot mode, one of the following sets of IDs will appear in that window.
Stock Bootloader
USB\VID_1949&PID_0006&REV_0100
USB\VID_1949&PID_0006​
FireFireFire Bootloader
USB\VID_18D1&PID_0100&REV_0100
USB\VID_18D1&PID_0100​
Windows identifies each USB device by these three numbers, the VID, PID and REV. Only these two sets of hardware identification numbers will appear when the Kindle Fire's bootloader is running. If the numbers differ at all, the bootloader no longer controls the device and therefore not in fastboot mode.
Linux users can use "lsusb -v" to get a list of all connected USB devices. The corresponding IDs are idVendor, idProduct and bcdDevice. Mac OS X users can use "system_profiler SPUSBDataType" and those IDs will be listed as Vendor ID, Product ID and Version in the list. The numbers are formatted slightly different than their Windows counterparts, but it's straightforward to determine what they are.
Methods for Enabling Fastboot Mode
Realistically, there are 3 potential methods of enabling fastboot mode on a working bootloader. There is a 4th method, but it should only be considered as a last ditch effort because the case must be opened for access to the motherboard. Let's cover the first 3 methods...
Factory cable - Using a factory cable is the most straightforward method of enabling fastboot mode on the Kindle Fire and it will work with any bootloader. With the device off, plug the cable into the Kindle Fire, then the computer and the device will boot up directly into fastboot mode. No other user intervention is required.
Temporary fastboot mode - The FireFirefire custom bootloader temporarily enables fastboot mode for a short amount of time. Issuing a fastboot command like...
Code:
fastboot getvar product
to the device during this time will stop the fastboot countdown and enable fastboot mode indefinitely. If the device displays a plain white and orange "kindle fire" logo, the stock bootloader is installed. The stock bootloader does not enable fastboot temporarily, so another method must be used.
Bootmode setting - The Kindle Fire has a bootmode setting that indicates to the bootloader how to proceed in its booting process. One of these bootmodes (4002) will tell the bootloader to enable fastboot mode. The bootmode setting is recognized by all bootloaders, so even the stock bootloader will go into fastboot mode when the bootmode is set to 4002. The only place this feature is likely to be used is from the system software, but there's a catch. The system must be able to provide access to a shell prompt.
For an unrooted stock device, use pokey9000's fbmode.
For a rooted stock device...
Code:
adb shell su -c 'idme bootmode 4002'
For a ROM with built-in root privileges...
Code:
adb shell idme bootmode 4002
If an error message similar to...
exec '/system/bin/sh' failed: No such file or directory (2)​appears when attempting to any of the above methods, the system cannot provide shell access. Consequently, the system will not be able to change the bootmode in this manner.
Making the decision
Then the choice of which method to use in order to enable fastboot is simple:
Do you have a factory cable available?
Does the device have a bootloader with temporary fastboot?
Can the device be booted into a system that can grant shell access?
With a working bootloader, the first question to which you can answer in the affirmative is your best choice. If the device does not have a working bootloader or you've answered "no" to all of the above, there's only one option remaining to you. Remove the back cover of the Kindle Fire to get access to the motherboard, short an exposed connection to the metal frame and employ pokey9000's Firekit. This procedure will set the device into USB bootmode and Livekit can upload a fastboot mode enabled bootloader through USB.
Getting out of fastboot mode
To get out of fastboot mode, make sure the bootmode is set to something other than 4002 and reboot the device. The examples below will set the bootmode to normal and reboot the device.
With the stock bootloader...
Code:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
With the FFF bootloader...
Code:
fastboot oem idme bootmode 4000
fastboot reboot
If a factory cable was used to enable fastboot mode, it must be disconnected before the bootloader loads again or it will go back into fastboot mode. You can quickly yank the cable after the reboot command has been issued, but it's probably safer to press and hold the power button for around 20 seconds to turn off the device, disconnect the cable, and turn it back on.
Using Fastboot commands and other information
There are many guides related to fastboot. Here are just a handful of starting points...

[Help] Busted my bootloader - SOLVED

Hello all,
I did a very stupid thing, i have wrongfuly followed this instruction
fastboot -i 0x1949 flash bootloader <name of firefirefire image here>
fastboot -i 0x1949 flash recovery <name of recovery image here>
instead of FFF image, i put in FFF.ZIP but successfully put in the openrecovery....img
Now my KF wont open, please help!
Do you think a Factory cable can bring it to life?
================================
SOLVED - KINDLE FIRE ALIVE!!!!
================================
What i Did.
1. Just follow the instructions in FireKit USB discussion
2. I had a hard time opening the KF, managed to break a couple of clips holding the pack panel, and scratch it a bit, but enough hold it back.
3. Tips: connect the USB end to the kindle first, then when you are ready connect the other end to the computer USB port, it is much easier.

yes u can do it with firekit live usb i have done
u can try firekit live usb i have done same thing and booted to yellow triangle but now it stucked

when i came out of the deep brick with the usb trick in firekit i had to oem format then i flashed new bootloader & recovery (being very careful, this time ) then
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot

thanks,
i will try FireKit USB. Just a question.
1. "fk" file contains all already right? the recovery and FFF.
2. I just execute the command to fix FF and twrp ?
3. do i need a separate file for FFF and TWRP?

1) Yes
2) You'll probably want to use the usb_install_fff_twrp script. If that doesn't work, try usb_fix_parts_and_install_fff_twrp, which also writes a new partition table and flashes the xloader
3) Older versions of both are included. These are sufficient to try to get your device back to a bootable state. You can upgrade them later.
In case the directions were not clear to you... you will very likely need to open up the back of the case and use the "shorting trick" to enable usbboot mode.

I did the exact same thing when working on one of the three KFs in my house (and I have been doing this for a long time). : )
By the time I found out about the fix I had also accidentally shorted out my USB port I believe and there was no bringing it back. At least Amazon was kind to me after I told them what I did and replaced the permanent brick with a new device (for a price of course). Now I look and relook before updating the boot loader. I hope your attempt works out for you.

one more thing,
do i need to keep the shorting connected or just until it give signs of life?
