I have a Fire HDX 7 on 13.3.2.5_user_325001120, Rooted, Safestrap 3.75 with Fire OS on Stock slot and ggow's HDX Nexus 2.0.2 on Slot-1. OTA updates are not disabled but no Wifi networks are added and Wifi is off within Fire OS.
I'm basically looking for clarification on the steps I need to take in order to unlock the Bootloader (for peace of mind and so that I can try out other ROMs freely).
To the best of my understanding I can Unlock with the following instructions:
Downgrade from 13.3.2.5 to 13.3.1.0
Download 13.3.1.0 .bin and script linked by kaeru00
If successful with the above I then proceed with the following to actually unlock:
All going well, I'm then unlocked and can proceed to install TWRP and ROMs, correct?

How to use it.
1. install Towelroot and Supersu using KFHDX Toolkit v 0.94
2. If Disable OTA update , Airplane mode ON and Enable OTA update
3. If Install SafeStrap, uninstall safestrap on App.
4. Put "update-kindle-1X.3.1.0_user_310079820.bin" in SAME folder,
5. execute install.bat
6. reboot
7. put update-kindle-1X.3.1.0_user_310079820.bin" in internal storage.
8. Downgrade, wait a minute on the update menu, because display update button to take time.
9. disable OTA update.
This batch file works "kindle fire hdx 7" ONLY
This is tested on version 13.3.2.5 and 13.3.2.6.

open command prompt to your ADB directory:

from these 2 results you get your the code we need, insert the last 2 digits of the manfID with your serial
following
like this: mmssssssss
download the attachment on the following post: http://xdaforums.com/show...2&postcount=46
Then place the file inside the attachement to C:\Python27 should be C:\Python\cuberHDX.py
open command prompt in: C:\Python27
replace "mmssssssss" with yours below:
Code:
python.exe cuberHDX.py 0xmmssssssss
that will put a new 0xmmssssssss.UNLOCK file in the Python27 directory
copy that file to your fastboot directory.
on an ADB prompt type
Code:
adb reboot-bootloader
then on a fastboot prompt type
Code:
fastboot -i 0x1949 devices
fastboot -i 0x1949 flash unlock 0xmmssssssss.unlock
fastboot -i 0x1949 reboot
thats it.
All going well, I'm then unlocked and can proceed to install TWRP and ROMs, correct?
