a couble of weeks ago y was trying to flash a new rom on my KFHD and bricked it, then tried going into fastboot and restoring system.img and after a failed attempt now my system wont boot at all, all i get is the orange KindleFire logo bootanimation and it freezes. i bought a factory cable on ebay but nothing happens when i plug it in pls help on troubleshooting this !
It could be a bad fastboot cable, have seen people buy them before and not work. I recommend the blackhat adapters myself that hashcode mentions on his 2nd bootloader + twrp tutorial.

It should switch itself on when you plug the cable in and boot straight to fastboot. If not then the cable could be bad.
The only difference between a normal cable and a fastboot cable is pin 4 has power from pin 1. Bodging a cable is an option.

hi all
I have a question, I have a Kindle Fire HD 7 with TWRP Recovery everything worked but the application nova launcher disappeared could not delete it or reinstall it so I did a wipe, but lost the root when you try to do it again had problems with coomand SU, with wire factory try doing a factory recovery with my backup.
appered after to restore a red screen and my computer does not recognize any new device
micro usb cable = kindle fire logo and red screen after
factory cable = fasboot logo and not recognize any device
not a problem for drivers is a problem with the tab
any ideas to fix?
tnx
Have you tried everything available to you first? This includes: factory resetting by booting into recovery and doing a whole system wipe, SD card included; see if you're at luck and ADB or fastboot still works by flashing the stock Amazon OS, assuming CMD still recognizes your fastboot.
Other than that, I'm out of options. I'd try to return it and hope for a refund or an exchange. However, you're only dealing with a soft brick, because if it's a hard brick, the whole tablet won't turn on at all, so at least it's not a paperweight at this point. I'd try to reach out to Hashcode or Soupmagnet or Reverendkjr on this forum and ask for help.
Yes, all that and tried
It sounds like your kindle updated to 7.3.0 the boot loader hack doesn't get along with that...read the last few pages in the boot loader three I think you'll fix your problem

SAME HERE PLEASE SOMEONE HELP ME!!! DONT USE KF First Aide tool!!!
Help the same thing has happened to me i need to get in to fastboot mode but i cant
any help would be great
is their a kindle fIre hd recovery tool from amazon as i cant boot up
this was the kf first aid tool that did this to me
There's actually a way I can think of, but I don't know if it will work. As long as you can find the bootloader files for the tablet, you can try to ask someone to JTAG your KFHD7. The process involves taking apart the tablet, using electricity to provide power while re-writing the bootloader so you can end up in fastboot mode. It's not very expensive, a regular Galaxy S3 takes 45-60 bucks and within a week. That's the only thing I have left for y'all.

So when you plug in your factory cable and power it on it enters fastboot.... correct? But then the computer does not detect the fastboot drivers? I'm a bit confused lol

Have you tried installing kindle first aide tool which can be found on a thread in this forum. I had the same problem with the red screen so I bought a factory cable, directed the computer to the KFF folder and installed the fastboot driver. After that the computer recognised my device and I was able to restore using option 3 of the first aide tool. Hope this helps. Good luck

jmar8124 is correct, my device enter fasboot mode but the computer no detect device.
Can you send fastboot commands to it? Try "fastboot -i 0x1949 reboot" and see if it reboots. As long as you can send fastboot commands to it, you're good to go.
Hey all,
So I have few questions about using the factory cable to fix my soft-bricked KFHD. If you want to read what I did to mess it up and what I've tried so far that's here in this thread but the TLDR is that I messed up my rooted kindle, won't boot, won't show up when plugged in (presumably ADB is off now) and so I ordered a factory cable from SkOpRn. I should get my cable today/tomorrow and I had a few questions before I start blundering about like a bull in a china shop. I've tried to read all the relevant threads here but some of the information seems conflicting/unclear. Here are my two clarification questions:
1) As I understand it, by plugging the device in with the factory cable I should be able to force it into a fastboot mode that allows me to issue commands. Assuming this works, do I continue to use the factory cable for the restore process or is the cable just a one-time "plug in" after which I use the standard cable to restore?
2) I was running 7.2.3 before things got messed up, so once I am able to get it to accept fastboot commands do I use kffirstaide to actually do the restore (Option 4: Completely Restore the KFHD 7.2.3)? I'm thinking along the lines of this guide here and using "Option 4" in "Step 16".
I'm probably over-complicating things but I hate to make things any worse by doing something wrong.
Thanks!

The fastboot cable is just a trigger. It tells the device to start up differently by powering a pin that does not normally have power. Once you see the fastboot screen, I recommend changing back to a normal cable. You really don't want that extra power hanging out ready to wreak havoc if there's any unexpected fault in the cable (especially if you got one from a random person on eBay).
With standard cable.If the device is recognized by adb then you can use this command:
Code:
adb shell su -c "reboot bootloader"
See the status kfHD have fastboot and you can go from there .

I don't know about kffaide but the restore tool in the dev section claims it replaces the boot loader when you flash 7.2.3

Thanks everyone all for the help! In case anyone else stumbles across this thread with a similar problem, let me summarize what I did to fix my KFHD7:
1. I used SkOrPn's factory cable to get the device into fastboot mode (I just plugged it in for a few seconds until fastboot came up and then switched to the standard USB cable).
2. Once in fastboot mode it was detected by my computer with no problems and I could issue fastboot commands.
3. As soon as I could issue commands I took no chances and used kffirstaide to flash 7.2.3. kffirstaide must provide the stock image because it installed and rebooted fine except without root. I do remember seeing somewhere in a dev forum an image of 7.2.3 that came pre-rooted but I couldn't find it easily. Since I had already rooted it once before it was no big deal to root again.
I can't believe I went from a soft-brick (not even being detected via usb) back to normal so easily! Thanks again for all the help and suggestions!
Hello.
I have a Kindle Fire HD that will power on. When plugged into the wall or the pc the logo flashes up for about 5 secs before the device switches back off. I have tried to reset it by holding down the power for 20 secs releasing and pressing it again, but nothing. Any help with this matter would be great!!!
Thank you.
You tried a fastboot cable? And are you sure the battery isn't dead?

Thanks for the reply.
It's not the battery no. I do not have a fastboot cable I will get one and try.
Cheers.
I got the fastboot cable now when it's plugged in with the new cable to the computer it comes on with "fastboot" on the screen, about 6 seconds later it powers off again.

leave it plugged into a charger for a bit, don't remember if it will charge off a fastboot cable or not but this is good news so far, its been sitting long enough i could see the battery being deadish so if you can get it to stay in fastboot longer you can restore it back to stock and get it running again.
Left it to charge all night, I can get SR Tool to start but it still powers off after a few secs. I have tried a different battery with the same result. I have also noticed there is no indication that it charges (Not sure if there should be one)
Well this sounds a bit more familiar now, I could throw a guess and say the bootimg is corrupt. You may be able too fix this though I advise using Ubuntu to do it because of the lack of driver issues and a better response time. If you run something like
Code:
fastboot -I 0x1949 flash boot boot.img
with the kindle unplugged, and plug in the fastboot cable when it says waiting for device, then it should attempt to flash the boot image again, and even if it fails it might give a better result, because I have seen what happens if a bad kernel flash happens before, usually it will kick the device straight into fastboot mode, so in your case it could be beneficial neither way possibly.

I have managed to flash the bootloader with the above method but still the problem persists. Thanks for the help with this matter, it is very much appreciated.
Interesting, that wasn't the bootloader though, that was more like the kernel +intramfs. If you want to give a shot at reflashing the bootloader you can download the one used in hashcode's 2nd bootloader process you use for downgrading. Just remember to verify it's md5sum or your kindle could brick even worse to the point soldering would be involved to fix it. Just flash it using the command he mentions in the tutorial.

ragigi and
Done as above, Still the same problem.
It said on both occasions that it successfully flashed correct?
Sent from my LG-P769 using Tapatalk
Yeah, It say's it flashed fine, On both occasions. Thanks.
That is odd then. Its not following standard fixing procedures... I have no guesses as to why it would still do that after successfully flashing the bootloader and the boot image. You might have to wait for someone with more experience to help. Or ask around in the freenode irc channel, hashcode may know more about what's up but someone else here might have an idea as well. I can't think of any other partitions that should cause this issue. In don't believe the boot0block being corrupt could do this, there are a few others I don't know what do but I don't think they should be responsible either but Idk. Sorry I can't be of much more help.

Hello to everybody, I'm new to this forum. thanks foe the useful informations I've been abler to gather on this website.
Yesterday arrived the fastboot cable I ordered.Pluggin it it it turned the kindle to fastboot mode.
Fastboot on my pc recognised the devide in cmd window.
After a couple of fastboot instructions attempting to reload bootloader and TWRP recovery without success, the kindle started to plug and unplug itself every second.
on the screen either if you use a normal usb calbe or the fastboot cable it appears the kindle logo, then the fastboot logo for 1 second then everything desappear and with the black screen starts endelessy to plug and unplug.
It seems fastboot doesn't find any device whine on program amanger it is correclty recognised by the system.
Any help would be very appreceated.
Thanks in advance, Stef
Just unplug the fast boot cable while the screen is black also could you pm me a video of your predicament? That could help
Tried to update the Kindle 7" Tate to MM tonight.
Flashed the ROM no problem but when it came to GAPPs philz recovery was blocking it for some reason.
No problem i thought i'll downgrade the ROM and use flashify to flash the TWRP bootloader.
Now i'm stuck on Fastboot splash screen whenever i turn on, tried the quick pull reboot but because i've messed the bootloader that was pretty unhopeful.
Worse problem is that i cant seem to find my fastboot cable.
Ive reinstalled minimal adb and fastboot and ive got the boot img ready to flash but i cant seem to get the device to be recognised with fastboot -i9 0x1949 getvar
Wish i'd just left the stupid device on lollipop now.
Any advice would be gratefully recieved.
p.s. As i hunt for my fastboot cable - am i looking for a cable with a micro usb or mini usb connector on? If im looking at the ports - which connector does it go in? Its soooo long since I first did the kindle.

Glad to report that my kindle 7" lives on.
Ordered a new fastboot cable, needed the google usb drivers installed and then simply ADB flashed TWRP recovery.
Now rocking CM13!
