How to fix your bricked KF2/otter2 with a red screen

Preparation:
Amazon recently fixed the secruity hole, that was used to flash second bootloader and TWRP recovery.
After you flashed TWRP recovery/second bootloader and rebooted the device you will see a red screen. You can do nothing at this point withoud a pc.
So to reopen the secruity hole you have to downgrade the bootloader via fastboot.
In order to enter Fastboot mode you have to have a fastboot/factory cable. The fastboot/factory cable is not the cable that came with your Kindle Fire!!! For more information about the factory cable visit this thread: http://xdaforums.com/showthread.php?t=1392693
Also you should set up all drivers and the Android SDK.
You can find the right drivers here!
Your device is not turning on? No sign of life? Then check this thread for hard bricked KF2s': http://xdaforums.com/showthread.php?t=2415870

Steps:
1.)Hold the power button for 20 sec. Your device will shut down
2.)Plug in your Fastboot cable and power on the device. Your Kindle should now be in fastboot mode (a green light should blinking)
3.)Download the Bootloader file: otter2-u-boot-prod-10.2.4.bin
md5sum: 5b03a7b428325de8d360ec201a745498
4.)Copy the file in to the same directory where the fastboot.exe is located
5.)Open a CMD window, navigate to your fastboot directory and type:
##############################################################
fastboot -i 0x1949 flash bootloader otter2-u-boot-prod-10.2.4.bin
##############################################################
6.)Disconnect the device and hold the power button for 20 sec again.
7.)Your device should now be working fine.

This may be a dumb question, but where is the fastboot directory? I'm reading this as a directory as in filesystem, i.e Device/sys/fastboot, something like that, but from glancing around, I'm failing to find anything remotely similar. Am I missing something or just misunderstanding the instruction?

I believe he meant the directory in which the fastboot application is located on your PC, which is typically your Android SDK folder / platform-tools.

My kf2 is on 10.4.1 but its still rooted after i fixed the red screen the first time. used kffaid to recover it to 10.2.4. Its working as a normal kindle with root now. So if i flash twrp again. Get a red screen. And then do what the first thread says. TWRP will be installed and i can install a custom rom then ?

That means you either don't have a factory cable or the factory cable you made doesn't work. BTW, a "factory cable" is not a standard USB cable.

i have the cable that came with the kindle and a few other cables and it worked before this 10.4 update.

Once again, a "factory cable" is not a standard USB cable. When people say "factory cable", they are referring to a factory programming cable. If you don't know what it is, you don't have one.

Need some help!

I just got my fastboot cable in the mail, did all the steps up until the typing the command into the prompt. I put the .bin file into the exact folder where fastboot.exe is located and everytime I run the command, it says: "error: cannot load 'otter2-u-boot-prod-10.2.4.bin'".
Can anyone help me please?!

Umm...did you check the md5 sum of that file before trying to flash it in fastboot?

Hello, sorry for the English, but I am an Italian boy.
I have red screen on my Kindle second generation.
I just got the factory and I CLABE fastboot with green light.
Unfortunately in my Windows 7 Ultimate, is recognized as the Kindle I otter2 - prod - 04.
Can you tell me where to download the drivers to be able to run my Kindle?
Thank you.

Davis6050 · Aug 5, 2013

I know i will sound stupid for asking this, but i need your help. Which drivers do i set up because i am not sure if i have the right one (Device manager says Kindle fire: android adb interface) also i have a android sdk with fastboot and they on the same page but when i type it in on the cmd it says it does not recognize fastboot. Is your version of fastboot the same as mine? And how will i know when it is done or when to disconnect. thank you!

Use this driver: http://xdaforums.com/attachment.php?attachmentid=1337103&d=1348009415
It's for the Kindle Fire HD 7'' but works fine for our Kindle Fire 2 as well.

Thank you, now my kindle in Fastboot is recognized by the PC as a Kindle fire.
I inserted the file otter2-u-boot-prod-10.2.4.bin in the directory where there is' fastboot.exe (in the platform-tools). I typed CMD and then fastboot-i 0x1949 flash bootloader otter2-u-boot-prod-10.2.4.bin but I received an answer: fastboot-i not recognized as an internal or external command, operable program or batch file

I do not understand where I'm wrong ....

flopower1996 · Aug 6, 2013

There must be a space between fastboot and -i
So the comand is:
Fastboot -i
