Thanks man !! You are my hero.
I could flash my Kindle Fire 2 which had the Stock ROM with version 10.5.1 following your indications. Now I have PACRom Up and running.

I will only add some links to download stuff.

How to flash a new ROM in your stock Kindle Fire 2.
I assume you have the "Minimal ADB and fastboot" ready in your computer as well as the drivers.
0- Check that when you connect the kindle in your windows computer, you see "Android Phone --> Android ADB Interface".
Is this not the case, it means your drivers are not OK. Google it.

1- you need root.
download the KingRoot app from here and install it in your kindle. KingRoot​
2- reboot your kindle
3- Now you need to download the files that you will have to flash.
4- Download ROM and Gapps
You can choose whatever ROM you like.
I tried LineageOS 12.1 but could not make it work. I could not go pass the wifi bug. Wifi bug .

And the corresponding Gapps. OpenGapps[/INDENT]

And now follow the process explained by @mikeataol
Boot normally
1- Boot normally your Kindle Fire 2 and copy these files in the /sdcard/ of Kindle fire. The ROM and Gapps will be copied later
Code: 
adb push [U]stack [/U]/sdcard/
adb shell su -c "dd if=/sdcard/stack of=/dev/block/platform/omap/omap_hsmmc.1/by-name/system bs=6519488 seek=1"
2- Now get in fastboot mode
You only need a normal cable USB cable. If you were able to copy the files to the sdcard, it means you have a good cable. Sometimes, some cables do not work. Try another one.
This command will get you in fastboot mode
Code: 
adb shell "su -c 'reboot bootloader'"
Once in fastboot mode
Now you will flash the other files that are in your computer
Code: 
fastboot -i 0x1949 flash bootloader [U]otter2-u-boot-prod-10.2.4.bi[/U]n
fastboot -i 0x1949 flash boot [U]otter2-freedom-boot-10.4.6.img[/U]
fastboot -i 0x1949 flash recovery [U]otter2-twrp-2.7.0.0-recovery.img[/U] --> watch out with this one, check it is the right version
Click to expand...
Click to collapse

i followed this till this point but now my kindle just has a black screen, anyone able to help?

I also bricked the device, won't turn on at all.

My device is (was) a X43Z60.

What I did:
I used the "bin4ry method" to get root. Pulled the backups, then, using files from https://github.com/jsheradin/otter2_misc/blob/master/README.md, I installed the "stack override" with adb shell su -c "dd if=/sdcard/stack of=/dev/block/platform/omap/omap_hsmmc.1/by-name/system bs=6519488 seek=1". Then I booted to Fastboot with adb shell "su -c 'reboot bootloader'". Then I ran:
Code: 
fastboot flash bootloader otter2-u-boot-prod-10.2.4.bin
fastboot flash boot otter2-freedom-boot-10.4.6.img
fastboot flash recovery otter2-twrp-2.7.0.0-recovery.img

After long holding the power button to turn it off, the device won't turn on again. Not with a normal cable, not with a fastboot cable. Absolutely black screen, no backlight when charging, nothing.

In the bin it goes or is there something I could still try?

    Introducing: Kindle Fire 2nd-bootloader + TWRP 2.6.3.0 for the Kindle Fire 2nd GEN

    *** USE AT YOUR OWN RISK! WHILE I TRY MY BEST TO PROVIDE WORKING KERNELS/ROMS, I AM NOT RESPONSIBLE IF THIS SOFTWARE OR ANYTHING I'VE WORKED ON SUDDENLY FRIES YOUR DEVICE. ***


    *** READ CAREFULLY BEFORE DOING ANYTHING ***
    *** Kindle Fire 1st-gen ROMs/KERNELS are *NOT* compatible with the Kindle Fire 2. Please only flash ROMs/KERNELS that are made for the Kindle Fire 2. ***



    ** IF YOU HAVE QUESTIONS, RE-READ THROUGH THE THREAD FOR ANSWERS. WHEN YOU'RE ABSOLUTELY SURE NO ONE HAS ASKED YOUR QUESTION, GO AHEAD AND RE-READ THE THREAD AGAIN AND USE THE SEARCH FEATURE. THEN POST YOUR QUESTION IF YOU STILL CAN'T FIND THE ANSWER **


    ** WHEN MOVING FROM AMAZON OS TO CM10.1 IN TWRP: "WIPE" -> "SYSTEM" AND "FACTORY RESET" TO CLEAR SYSTEM/DATA/CACHE. YOUR APPS FROM AMAZON ICS AREN'T COMPATIBLE. IF NOT YOU'LL LOOP ON THE CM10.1 BOOT ANIMATION **


    [03/27] NEW support thread for OFFICIAL CM on the Otter2 (Kindle Fire 2):
    http://xdaforums.com/showthread.php?t=2209995


    ** YOU SHOULD HAVE A WORKING FASTBOOT CABLE + FASTBOOT DRIVERS/ACCESS ON YOUR PC. **

    Q: How do I know if my fastboot works?
    A: Plug the cable into your device and then the computer. Reboot the Kindle. It *SHOULD* show a Fastboot screen. Once at the screen use this command on your computer:
    fastboot -i 0x1949 devices
    You should see something like this:
    0123456789ABCDEF

    Here's 1 website you can purchase a FASTBOOT adapter from (works with your normal USB cable)
    http://shop.teamblackhat.info/Factory-Adapters-motadapt.htm
    ** I don't make any commission or fee from the sales of these devices, I just know they have them on stock most of the time and ship in a reasonable time frame unlike the Chinese variants found on ebay.

    If you do NOT see this, then make sure you have the SDK installed correctly and you have the right setup for fastboot on your PC before proceeding.


    *** BE SURE YOU HAVE A GOOD CHARGE ON THE DEVICE ***


    INITIAL SETUP INSTRUCTIONS (1st TIME ONLY) FOR 2ND-BOOTLOADER + TeamWinRecoveryProject INSTALL:

    STEP 1. Backup your stock partitions to your own HD for later if you need disaster recovery:
    Code: 
    adb pull /dev/block/mmcblk0boot0
adb pull /dev/block/platform/omap/omap_hsmmc.1/by-name/boot
adb pull /dev/block/platform/omap/omap_hsmmc.1/by-name/recovery
adb pull /dev/block/platform/omap/omap_hsmmc.1/by-name/system # This will take a few minutes
    Take those files and put them somewhere safe.


    STEP 2: Download the files you will need to install 2nd-bootloader, TWRP and CM10.1:
    1. Stack override file:
      http://goo.im/devs/Hashcode/otter2/stack
    2. [12/09] otter2-freedom-boot-10.4.6.img (USED ONLY THE FIRST TIME -- .zip files will have their own boot.img's from now on):
      http://goo.im/devs/Hashcode/otter2/otter2-freedom-boot-10.4.6.img
      md5sum: 80f9b9ba80910de361463560f86f315a
    3. [09/03] TeamWin Recovery 2.6.3.0:
      http://goo.im/devs/Hashcode/otter2/otter2-twrp-2.6.3.0-recovery.img
      md5sum: a66a8cbab92fd5daaa85f6303e9cc0c3
    4. older 10.2.4 bootloader file and flash to your device via fastboot:
      http://goo.im/devs/Hashcode/otter2/otter2-u-boot-prod-10.2.4.bin
      md5sum 5b03a7b428325de8d360ec201a745498
      (You SHOULD check the MD5SUM before using fastboot -- downloads CAN be corrupted)
    5. CM-10.1/CM-10.2 for the Kindle Fire 2 (choose the latest version from):
      http://www.get.cm/?device=otter2
    6. Google Apps from: http://goo.im/gapps (choose the version: CM10.1 or CM10.2)
    Place the ROM and the gapps .zip on your device in the /sdcard area


    STEP 3. Install the stack override in /system:
    ADB commands entered while booted up into STOCK *rooted* Amazon Kindle OS -- May need to enable ADB debugging in Settings:
    [2013-08-21] edited the location where stack is placed on device due to permissions changes
    Code: 
    adb push stack /sdcard/
adb shell su -c "dd if=/sdcard/stack of=/dev/block/platform/omap/omap_hsmmc.1/by-name/system bs=6519488 seek=1"

    [ Connect fastboot cable, and reboot the device so that "Fastboot" is showing ]

    STEP 4.
    Flash the OLD bootloader, new otter2-freedom-boot.img and TWRP recovery.[/B]
    *DONT RE-FLASH FREEDOM-BOOT.IMG LATER AFTER FLASHING CM10.1 -- IT'S FOR STOCK AMAZON OS ONLY / FIRST INSTALL ONLY*
    Code: 
    fastboot -i 0x1949 flash bootloader otter2-u-boot-prod-10.2.4.bin
fastboot -i 0x1949 flash boot otter2-freedom-boot-10.4.6.img
fastboot -i 0x1949 flash recovery otter2-twrp-2.6.3.0-recovery.img
fastboot -i 0x1949 reboot

    ** If everything was done correctly you will at this point see the bootmenu with a BLUE logo during the reboot. **

    TO ENTER RECOVERY:
    During the blue logo screen press the power button to cycle through options and select "Recovery" to enter TWRP.

    Once in TWRP you can Install" the CM-10.1/CM-10.2 by selecting "Install" and then browsing the device and selecting it, then "Add Zip" and select the Gapps .zip as well.

    Use the slider to start the install.


    FLASHING BACK TO STOCK:
    ** FIND THE FILES WE BACKED UP IN STEP #1 OR DOWNLOAD NEW ONES FROM THE RECOVERY THREAD HERE: **
    http://xdaforums.com/showthread.php?t=2035047

    Once you have these files (we'll name them boot.img/recovery.img and system.img for the purpose of these instructions, but they could be different on your system).

    Plug in your fastboot cable and reboot so that you see the fastboot screen and enter the following commands:
    Code: 
    fastboot -i 0x1949 flash boot [B]boot.img[/B]
fastboot -i 0x1949 flash recovery [B]recovery.img[/B]
fastboot -i 0x1949 flash system [B]system.img[/B] # This one will take a few minutes
fastboot -i 0x1949 reboot

    Enjoy
