I did something similar the first time I attempted recovery install. Fastboot cable is very recommended for the FK2.

Any chance we can get this updated with the 10.4.6 kernel? Thanks for all your time!

Done all the steps one by one and ensured using the binary and qemu method I had root (double checked with root checkers) got the blue bootloader screen but won't boot into recovery just sits there on the blue screen saying booting I've tried fastboot erase cache but nothing, can't get into recovery and can't even boot into stock just getting the red triangle and the reboot reset to factory options.

Any advice, no fastboot cable lol ;) what can I say I like living life on the edge. (And hate spending money if not needed too haha)

This sounds like the recovery.img didn't flash correctly. Can you re-download this file:
http://goo.im/devs/Hashcode/otter2/otter2-twrp-2.6.0.0-recovery.img
md5sum: 54cd3fda08c51de2667e3bf82487a055

And flash it with fastboot:
fastboot -i 0x1949 flash recovery otter2-twrp-2.6.0.0-recovery.img

(If you can enter fastboot mode)

I got a Kindle fire 2 up and running CM10 great a while ago, now i'm trying to install CM10 on another KF2, but struggling to push the Stack file using ADB, error says not a directory? Any ideas?

I can not thank you enough for this guide Hashcode and all those involved. I bought a KF2 about a month ago. Coming from the original KF I figured this process would be just as simple. Boy was I wrong! I've successfully flashed TWRP and am now in the process of installing CM 10.1. I am beyond ecstatic. I couldn't manage to do it on my windows system for some reason... but now that I have accomplished this I realize what my mistakes were (I think). But of course... Linux comes to save the day. I also ran into the adb push stack /sdcard issue, but thankfully the additional backslash fixed it. Everything from there was a cakewalk... minus the corrupt bootloader flash that I had to re do. I MD5SUM'd it and knew my DL was good, so a reflash fixed me right up.

You need a fastboot cable if you have the stock bootloader to get into fastboot.

    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
