[TUT] Unlocking your Kindle Fire HDX 7 Bootloader

Hello, welcome to my to my guide on how to unlock your Kindle Fire HDX 7's bootloader. This guide is for mac.

I will be nicknaming the Kindle Fire HDX 7 as thor.

I will be assuming you have TWRP and flashed the .3.2.3 bootloader upgrade and ADB/Fastboot.

Steps:

Go and get python 2.7.X (X = Doesn't matter.)

Open up a terminal window and paste this command in:

Quote:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Now, press enter.

So, now what to do? Well, heres the next thingy

Type this in the terminal:

Quote:

brew install gcc brew install mpc brew install mpfr

Done.

Now type:

Quote:

pip install gmpy2

BAM! You should now have GMPY2 installed.

Now, download this:
cuberHDX.py

Place on desktop.

Open up a ADB Window and type:

Quote:

./adb shell cat /sys/block/mmcblk0/device/manfid cat /sys/block/mmcblk0/device/serial

Now, type the last 2 digits of your manfid and serial.

M = last 2 digits of Manfid Serial = Your serial code

MMSERIAL

Okay, now open up a terminal window and go to your desktop/folder with cuberHDX.py

Type in this:

Quote:

./cuberHDX.py 0xMMSERIAL

This will make a file called 0xMMSERIAL on your desktop, if not do a search for it on your computer.

Next drag that file into where your fastboot is

Now, type in this:

Quote:

./fastboot -i 0x1949 devices

Your device should pop up.

Quote:

./fastboot -i 0x1949 flash unlock 0xmmssssssss.unlock

Next, wait 5 seconds.
Now, check your screen if it says UNLOCK CODE CORRECT, or something similar. If it doesn't, make a new file with the correct MMSERIAL Code.

Quote:

./fastboot -i 0x1949 reboot

BAM! you now have a unlocked bootloader THOR.
