That's because you typically don't need to restore the boot0block. It should persist across ROM switching, but you never know. That's why the backup's called for - to futureproof yourself in the event that the original partition gets wiped.

After I restored the other 3 files, I later realized I didn't do boot0block since it wasn't in the instructions. But I got through the initial setup okay and it mostly works with one weird problem.

I'm wondering if maybe this is why I have an odd problem with my FireOS where it tells me my password is invalid for either In-App Purchases or if I go to toggle In-App purchases off and on under Apps. The password works for everything else like initial setup of the JEM, using it on Amazon's page in Silk and so on.

I'm wondering if it's "safe" to restore my backed up boot0block to a "mostly" working FireOS without having to go through the initial setup yet again. After the first restore when I noticed that issue, I tried my other backup from KindleFireFirstAide, did setup again, but still have the same problem.

I don't think restoring the boot0block would interfere with your data. Obviously make a backup before you try it out, but I'd see how it works after restoring boot0block.

Well this is a head scratcher. I didn't do anything for several days, and found the time tonight to restore my backed up boot0block. However, trying it one more time before I did that, the problem "magically" disappeared and I can now do In-App Purchases. So for some unknown reason, after several days, the problem just went away. I'm thinking that maybe it just needed enough time to get status updates from the Home Planet. I wouldn't imagine that the password would be stored/updated locally so I'm puzzled, but one never really knows. Thanks for the ideas

I can't download the OPs files without some type of warning. I either get that flash is outdated and wants to update, or I get redirected to a porn site, or I get a bogus warning telling me to call Microsoft to prevent my computer from being locked. I will look elsewhere for the files since Dev-host seems to be corrupted.

where can i find good download links?

i have been having the SAME problems across all posts here in Amazon 7" Kindle Fire HD, 8.9" Kindle Fire HD, Kindle Fire 2.

this tablet is (relatively) a dinosaur, so this is ALMOST a dead section. i have been trying to get the file kindle fire first aid and ALL links are DEAD. google searches either point to X-DA or to a site that TALKS about the file and then.. . . . POINTS TO X-DA to get the file.

good luck, this section is in need of a good clean-up and updating.

I need some help here. I want to install a ROM on my 8.0" Kindle Fire HD. My understanding is that I need:

- install 2nd bootloader
- fastboot access
- root device

I've connected the device to my computer (Windows 10, x64) and the instructions in the original post to get into Fastboot Mode are not working for me. I ran:

fastboot -i 0x1949 getvar product

then plugged the device into the PC, booted it up, and no Fastboot Mode. I'm in 8.5.1, if it matters. How can I get this process to work?

There is a common issue with the newest drivers from Amazon preventing Fastboot mode: this has been encountered and confirmed by several users in the forum.
Check this recent discussion (and the linked ones) with hints to install other drivers that work as expected:

Introducing: Kindle Fire 2nd-bootloader + TWRP 2.8.x.x for the Kindle Fire HD 8.9

*** 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. ***

** THESE FILES WILL ONLY WORK ON A KINDLE FIRE HD 8.9. DO NOT ATTEMPT TO USE THESE FILES ON ANY OTHER DEVICE. **

** WHEN MODDING THE KFIRE HD YOU SHOULD HAVE WORKING FASTBOOT DRIVERS ON YOUR PC. **


FASTBOOT CABLES ARE NOT REQUIRED FOR USING FASTBOOT MODE ON THE KINDLE FIRE HD 8.9.
DOWNLOAD THE ANDROID SDK AND GO FROM THERE.
POSSIBLE ALSO THAT USING A FASTBOOT CABLE ON THE 8.9 WILL CAUSE DAMAGE.

http://developer.android.com/sdk/index.html

http://xdaforums.com/showpost.php?p=41199927&postcount=230

Q: How do I know if my fastboot works?
A: With the Kindle powered down, type the following command into a cmd/terminal window on your PC (should return with: < waiting for device> ):
fastboot -i 0x1949 getvar product

Then connect USB to the Kindle and reboot. It *SHOULD* show a Fastboot screen and your terminal window should show something like:
product: Jem-PVT-Prod-04

Type this to reboot out of fastboot mode:
fastboot -i 0x1949 reboot


** 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 **



INSTRUCTIONS FOR INSTALLING A 2ND-BOOTLOADER TO LOAD CUSTOM KERNELS / ROMS / RECOVERY:
*** BE SURE YOU HAVE A GOOD CHARGE ON THE DEVICE ***

STEP 1. Backup your stock partitions to your own HD for later if you need disaster recovery:
Code:
adb shell su -c "dd if=/dev/block/mmcblk0boot0 of=/sdcard/boot0block.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/boot of=/sdcard/stock-boot.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/recovery of=/sdcard/stock-recovery.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/system of=/sdcard/stock-system.img" # This will take a few minutes
adb pull /sdcard/boot0block.img
adb pull /sdcard/stock-boot.img
adb pull /sdcard/stock-recovery.img
adb pull /sdcard/stock-system.img # This will take a few minutes
Take those files and put them somewhere safe.

**** MAC USERS MAY NEED TO SPARSE THE FILES FOR RE-FLASHING TO THE DEVICE. I NEED A MAC USER TO PROBABLY WORK THROUGH THAT PROCESS AND I CAN POST BACKUP COPIES OF THE STOCK PARTITIONS FOR DISASTER RECOVERY ****



STEP 2: Download the files you will need to install 2nd-bootloader, TWRP and CM:

ON THE FOLLOWING DEV-HOST LINKS
USE THE BLUE "DOWNLOAD NOW" BUTTON
-- DO NOT INSTALL AN EXECUTABLE DOWNLOADER TO YOUR SYSTEM! --
I'LL LOOK FOR A BETTER HOST WHEN I GET MORE TIME.

  1. Stack override file:
    Mirror 1: Download "stack" from Dev-Host
  2. [12/09] kfhd8-freedom-boot-8.4.6.img (USED ONLY THE FIRST TIME -- .zip files will have their own boot.img's from now on):
    Mirror 1: Download "kfhd8-freedom-boot-8.4.6.img" from Dev-Host
    md5sum: 8374cf88e75abda8c374044a1f0daa5f
  3. [06/24] TWRP 2.8.7.0 recovery flash Image
    Mirror 1: Download TWRP from Dev-Host
    md5sum: a0c7533fd853849184850580350abd18
  4. CM-12.1 for the Kindle Fire HD 8.9 (choose the latest version from):
    Mirror 1: Downloads CM
  5. Google Apps from Android File Host:
    https://www.androidfilehost.com/?w=files&flid=25361 (Use 5.1 version!)
  6. Download the older 8.1.4 bootloader file and flash to your device via fastboot:
    Mirror 1: Download bootloader from Dev-Host
    md5sum a56f24c0c01aaea4bf408bc710faadaa
    (You SHOULD check this before using fastboot -- downloads CAN be corrupted)
Place the CM-12.1 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"

STEP 4. Stop the auto recovery update script (this file may or may not be present):
Code:
adb shell su -c "mount -o remount,rw ext4 /system"
adb shell su -c "mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak"
adb shell su -c "mount -o remount,ro ext4 /system"

STEP 5:
[ With the device powered off: Issue the following commands into your command/terminal window on your PC. Start with the first command and press enter. Then connect USB to the Kindle and power on ]


Code:
fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin
fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.4.6.img
fastboot -i 0x1949 flash recovery kfhd8-twrp-2.8.7.0-recovery.img
fastboot -i 0x1949 reboot

*DONT RE-FLASH FREEDOM-BOOT.IMG LATER AFTER FLASHING CUSTOM ROMS -- IT'S FOR STOCK AMAZON OS ONLY / FIRST INSTALL ONLY*

** If everything was done correctly your Kindle will reboot and you will at first see the normal Kindle Fire ORANGE logo and then it will fade and come back as a BLUE logo. **

TO ENTER RECOVERY:
Press the left volume button (volume up) while the logo is still YELLOW and keep pressing until the logo turns BLUE. Wait a moment and you should enter recovery.


STEP 6:
CM-12.1 AND GAPPS INSTALLATION:
  • (OPTIONAL) Make a backup by selecting "Backup" and then slide your finger to the right on the "Swipe to Back Up"
  • Once complete use the pentagon "Home" icon in the upper right corner of the screen (next to the back arrow and terminal icon)
  • Now, select "Wipe"
  • Swipe the "Swipe to Factory Reset"
  • Use the "Home" icon
  • Select "Install"
  • Browse to the location on your device where you saved the CM-11.0 / GAPPS .ZIP files
  • Select the CM12.1 ZIP file in the list by touching it, then confirm it says the name of the CM-12.1 .ZIP file on the next screen under "File to flash:"
  • Select "Add More Zips"
  • Select the GAPPS ZIP file in the list by touching it -- make sure it says the name of the .ZIP again under "File to flash:"
  • Swipe the "Swipe to Confirm Flash", and wait for it to finish.
  • If the screen is blank at any time you can hit the power button to "wake up" the device
  • Once the flash is done, you'll see a "Home" and "Reboot" buttons at the bottom of the screen
  • Select "Reboot"

CONGRATULATIONS YOU NOW HAVE THE ABILITY TO INSTALL CUSTOM KERNELS / RECOVERY AND ROMS.


FLASHING BACK TO STOCK:
** FIND THE FILES WE BACKED UP IN STEP #1: ** OR Follow this thread's instructions:
http://xdaforums.com/showthread.php?t=2011126


**** MAC USERS MAY NEED TO SPARSE THE FILES FOR RE-FLASHING TO THE DEVICE. I NEED A MAC USER TO PROBABLY WORK THROUGH THAT PROCESS AND I CAN POST BACKUP COPIES OF THE STOCK PARTITIONS FOR DISASTER RECOVERY ****


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


THANKS TO:
  • fattire for finding the original bootloader exploit
  • verygreen for doing some initial work on the 2nd-bootloader and fixing bugs (and letting me copy some of his bootloader installation instructions)
After days of being stuck in fastboot, I just did your step 5 and ONLY step 5. I'm BACK much thanks!! I owe you. Then I used twrp to load lineage 14.1 and slim gapps. All is well. Thanks again

Its been a long time since I have been on here. but now I have a problem. my kindle has worked flawlessly since I have done these mods back in the day. gave my kindle to my father in law to play around on. now it seems it doesn't want to charge, kind of. with the device powered off, I plug in a cable and it turns on. after it is booted up its not charging. now if I power it down with the cable still plugged in and leave it alone for a while it will charge even though it doesn't give me charging icon when it is off. now my question is this, is the battery shot? do I need to flash a new rom? Or just flash it back to stock and start over. I believe I still have the original file saved on some where.

    Who thinks I should write an APK installer for the initial installation of the 2nd-bootloader, TWRP and an automated re-install of the Amazon OS to fix any damage the stack drop did?
