ever since flashing the latest rom, charging for me has been really slow, i went from 31 percent to 60 in 4 hours, when the screen is off, the orange indicator light is on, but when the screen is on the indicator light is off, and under status in settings it doesnt say it's charging but the circle indicator in the right hand corner shows that its charging. could this be the result of a bad flash? only had the kindle for about a week, hate to tihnk i've damaged the charger plug

Those images are not fastbootable. They are only for twrp, if you have a backup of the twrp folder from your sdcard, and you for whatever reason need to start from stock again, push the twrp folder back to the sdcard, then while in twrp, restore that backup.

Just use the restore utility if you have problems your find it on the first post.

Actually, now that he has recovery images, he doesn't need kf2-srt.

so basically you guys are saying if I forget to flash a kernel or something like that and I get stuck in boot loop I can just use twrp? and I have ordered my fastboot cable just in case and thanks for the fast replys means a lot :)

That's exactly what I mean. if you get stuck at the orange kf logo before the blue one, you will need a fbcable, Fastboot is currently included in second boot (the blue logo) If you need, you can use fastboot in the second boot with a normal cable.

How would you achieve fb in the blue logo it just comes up booting dissapprears or you have to select reset boot recovering or reboot?

Both 1st and 2nd gen Kindle Fires were submitted to CyanigenMod review 2 days ago.

I'll check in with them today to see where we're at.

How can I back to stock rom from TWRP? I'm currently at CM10.1 but the battery life is disappointed. I have no Stock rom backup.

Need to find some one willing to share there back up with you

Wrong answer. Those annoy me even more than answering questions that have been answered over and over.

Edit: i was wrong. Leaving this here as an example of how NOT to act on XDA. The irony.. :banghead:

Actually that was the perfect answer... he asked for within twrp not a different tool

Lmao. I apologize for my previous statement.

1. Because i was wrong
2. Because i was a douche about it.

I really am sorry though.. I was in a pissy mood earlier and should know better.

Thanks fmkilo for correcting me.

There are two different ways i can suggest:
1. Try this tool- it will download the system images and do all the heavy lifting for you-
http://xdaforums.com/showthread.php?t=2096888

2. Or, you can do what i did.. I got the dropbox download location from the runme.bat file and downloaded the files, then ran the fastboot commands manually.. Just look in the batch file for "option1".

I've been back and forth a couple times now just playing with things. I've become foolishly confident with my fast boot cable on hand. I still can't seem to make a cwm flashable zip for stock though.. Just not sure what I'm doing wrong. If i ever figure it out i promise to share :D

    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
