Kindle only shows red screen

Ok im posting in hopes to help someone else and myself.
DEVICE: 1st Gen Kindle Fire (D01400)
PROBLEM: Kindle quickly flashes stock logo then displays red screen.
I created this problem by using the wrong root tool (Qemuroot) [This tool is made for a Kindle Fire HD]
I bought a fastboot cable i hopes to use KFU/KUU to unbrick the device.
However Windows 8 only shows the device driver listed as Otter2-Prod-04 (Unknown Device) I proceeded to install the ADB drivers, even manualy assigned the device driver, and disabled driving signing and reinstalled drivers. (Drivers appear to install correctly however won't show up in connected adb devices.)
At this point im going to use SoupKit. I will post the outcome.
If you have had a similar problem or know of a fix which I have yet to research please let me know.
Thanks

Tested with Ubuntu linux using soupkit & firekit.
Both resulted in <Waiting for Android device> same in windows as well.
So I tried another computer also running windows 8, installed fresh SDK/Java/Drivers.
Once again had to force the driver to replace the unknown device "Otter2-Prod-04" now the device says its working in device manager yet nothing in ADB or fastboot.
I will add when I plug the device in using the fastboot cable it shows a red fastboot text and a stoplight green is flashing.
At this point im stuck and have reached the end of google. Yup thats right the very last page.

More hours put into this. I can issue fastboot commands. So this now turns into a question.
Is it possible to restore my kindle using fastboot?

You should be able to if you can push fff and recovery over and flash them via fastboot
Should enable you to have recovery back and work from there

Well I killed my kindle.
Pushed the FFF via fast boot and now the device no longer powers on, no lights, no sign of life.
fastboot -i 0x1949 flash bootloader <name of firefirefire image here> which was u-boot
guess its time to cash in on my my rapid exchange at Best Buy

New battery ? Can you explain never heard of this before. I was under the impression that I killed the bootloader.

I was just thinking that the battery may have died

[Q] Kindle Fire 2 Bricked BootLoop

My kindle fire is stuck in a boot loop (i think) it just keeps saying "Kindle Fire" then restarts then says the same thing and does this for ever in this state the computer doesnt find the device. I have a fastboot cable and it does put the device in to fastboot. Then I switch the fastboot cable with a regular kindle cable then it finds the device as otter2-prod-04. This all happened when I was trying to put twrp on it. And I think I rooted it.

If it shows up now as otter on your PC you just need to use fastboot to reflash the system image. If you are have an exclamation mark in the device manager you need to install the adb drivers for it when its in fastboot mode.

Thanks for the reply but another problem that i forgot to mention is that neither adb nor fastboot find the device.

Check the device manager for an an exclamation mark then also, what fastboot command are you running? If you don't run the command with -i 0x1949 it won't detect it. So for a test try running "fastboot -i 0x1949 getvar product".

when I run that command it only says <waiting for device>. And also in device manager it has a exclamation mark.

Then u need to tell it to install the adb drivers for the device with the exclamation mark. That would be the reason the fastboot command isn't working. If u have rooted it then you should have the appropriate drivers laying around somewhere for adb mode. If not send either rpost back or pm me, and I will link u to my drivers I customized for kindles, though I am unaware if they will work with kf2 as is because I don't have its pid, only the vid may be the same, if that's the case I can always fix it and reupload it.

I also have a kindle fire second generation. But it's in a different bootloop, with the first bright white and orange kindle logo repeating every 10 seconds or so. Nothing else. No adb, no fastboot. Not recognized by the computer at all! Could you please help?

Sounds like you will need a fastboot cable to attempt fixing that.

Please help to unbrick---stuck in red Screen and can't get into fastboot

Unluckly i bricked my kindle fire hd 8.9.Now when i press the power button,after the yellow kindle fire logo flash,it will stuck on the red screen.And when i connect it to the PC,i got the red screen again.By the way,when the yellow kindle fire logo shows up, the PC could recognize the tablet but in less than 1 second the red screen will come out and the tablet will be disconnected from the PC as if the USB cable is pulled out.(i could hear the sound of disconnecting USB device.)
I also made a fastboot cable but it truned out to be invalid.Did i hard-brick the tablet? Is there any possibility to unbrick it? (I'm not a native speaker so sorry for my poor English)

These don't use fastboot. Use the regular USB and Has codes thread for 8.9" tablet for instructions to factory reset. Red screen on this is lack of bootloader.

Once the tablet is connected to the computer it will fall into red screen and become invisible to the computer in 1 second so the computer is not able to recognize the tablet.How can i install the necessary drivers?
BTW,you mentioned the instructions to factory reset,could you give me the link of the thread?

I would suggest using a Ubuntu 13.10 live CD in your case since you never installed the fastboot driver previously. Makes things a lot simpler since you won't need to install drivers, only the fastboot command. Should be able to install it from the Ubuntu software center, just search for fastboot.

I have opensuse installed in my PC but that doesn't work either. Connect the tablet with the computer and the red screen shows up then the connection breaks and the tablet become invisible to the PC,just the same situation as it is in windows.

Yes but here's the thing, it's supposed to do that. You basically run in a terminal "fastboot -i 0x1945 getvar product" and after it says waiting for device you plug your kindle in while it's off. That way once its detected for a brief moment it sends the command and goes into full fledged fastboot. Never had an issue with it in Linux before, then again I have never red screened my kindle and mine's a 7" model so a fastboot cable would have worked on mine.

Thank you for you reply.I'd like to know if I could use this method in opensuse?

Should be able to as long as the kernel supports the device, anything modern should. I had native drivers in 10.04 of Ubuntu so it's safe to bet you have the kernel drivers. If you can't get it to work in suse, just try a live distro like I said, though I don't think there's a need to, but I have never tried suse before, I stick to Debian based distros.

I tried thay in suse but it didn't work.I think when the yellow kindle fire logo shows up the tablet is in fastboot mode but I'm just wondering why the tablet can't stay in fastboot after the screen truned into red.

Because it's not supposed to... The 8.9" models don't work with a fastboot cable so instead they made it so it will briefly appear as a fastboot device when the boot loader initializes, and if a command gets passed to it while its briefly like this it gets told to go into full on fastboot mode. That red screen you're seeing is not it trying to go into fastboot, its just a messed up bootloader, but it should still be intact enough to reflash the bootloader to fix this. Weird to suggest this at this point but maybe try using an Ubuntu live CD and see what happens... I don't know why suse wouldn't work but maybe give it a shot.

So your suggestion would be
step1，Download a Ubuntu live CD image file，write the image into a usb disk，and reboot into the live CD.
step2，Open a terminal，input the fastboot command，then connect the tablet to the PC when the terminal says"waiting for device"
step3，Then the tablet should stay in fastboot and it is now possible to fix the bootloader and system with fastboot command.
Did I understand that correctly？

And since my tablet is dead now， is it possible to install the fastboot driver in windows without the tablet？

It would be very difficult' unless you can get the driver into the driver cache but I haven't looked up how to do that, also on Ubuntu you will have to install the fastboot command, it should be in the Ubuntu software center, I'd give u the terminal command but I don't know the package name offhand.

Just out of curiosity have you tried KFFirstAide?

used factory cable now what?

hi got my usb factory cable my kindle now boots into fastboot ie: the traffic lights but still not being picked up by adb any advice?

also using fastboot command just say waiting for device... checked device manager doesnt show up? is this a hardware issue?

It should appear as a device called otter2 if its a kf2, if that ever appeared in the device manager then the drivers in my signature are meant for it, just right click the device and hit update drivers in the device manager, and point it to where you would have extracted mine. Also fastboot needs some special parameters on kindles, you have to run a command so it looks something like this:
Code:
fastboot -i 0x1949 getvar product
the "getvar product" part is just the command it would be sending but the other part is what's important. Try running that command and seeing what happens.

Hi think this is the issue windows doesn't even make a noise and shows nothing up in device manager it. Windows isn't detecting anything being plugged in.

Sorry I run the command just says waiting for device

Did you switch cables after entering fastboot?
Sent from my SAMSUNG-SGH-I317 using Tapatalk

yes tried that too

Hi just an update on what happens
On normal power up kindle fire logo appears then screen goes black no power light either
On fastboot cable get fastboot screen with green flashing traffic light.
On both cables USB on the PC is not pick ed up its not a driver issue windows just does dectect anything plugged in.

Interesting, wonder if the USB plug went bad on the kindle, could always probe your USB on a Ubuntu live CD to double check but idk if you wanna put that much effort into it.
Sent from my Amazon Kindle Fire HD running CM10.1 Tablet UI using xda-developers app

I already have Ubuntu installed what is the command for that

did anyone find the commands?

ok i opened it up today and looked at the usb looks fine no damaged pin's?

One command u can try is lsusb, it lists USB devices plugged in, should list it as a lab device, Don,t remember the specifics, also u can also run dmesg and see if the device showed up as plugged in in the log.

[Q] [Help] Red Screen Bricked KF2 [Have Fastboot Cable]

So I managed to brick my rooted Kindle Fire 2nd Generation after trying to install a rom with TWRP app. Anyways, I have a fastboot cable, and the correct drivers and Android SDK, but when I plug in my cable, turn off the device (holding button for 20 seconds), then turn back on, it still goes to red screen immediately after the brief kindle fire logo, exactly the same without fastboot cable. What am I dong wrong?
Would really appreciate any help .
-Thanks,
Jacoobyman

You sure the fastboot cable works? If it does I would keep the device manager open and see if it is briefly being recognized as a adb device or not. If it briefly detects it then I would attempt a "fastboot -i 0x1949 getvar product", then plug the kindle into fastboot cable while off and see if that works, and yes I know that is typically meant for a 8.9" model but if its a weird circumstance then it couldn't hurt to try.

No it does not detect it at all in device manager. not even briefly. :/

That sounds bad, I don't trust windows too much for debugging but I'm guessing Linux would say the same thing, what were you trying to flash that caused this?
