You will need a linux box or python installed on windows. Find instructions on the web for that.

Step 1: Download attachment
Step 2: Run command and make note of code return

Code:

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

Step 3: Run command and make note of code return

Code:

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

Now you should have 2 sets of numbers. first should be in the format of 0x0000XX where XX is numbers. And the other is 0xSSSSSSSS.

So now use the downloaded file and execute (obivously replacing the entries with what was returned above.

Code:

./cublock.py XX SSSSSSSS

This will tell you you have unlock.signed now. So move that to your fastboot/adb directory and then reboot to bootloader and issue this command

Code:

adb reboot-bootloader fastboot -i 0x1949 flash unlock unlock.signed

Once done, get back to android and do the following:

Code:

adb shell su idme print

You should now see unlock_code: AAAAAAAA and on and on.

Now go flash my TWRP build in OG dev

Original credit goes to @dpeddi & @vortox for the exploit. I did nothing to this code and it is all their work. So give them thanks

Sorry for the noob-ish question. How do you get adb to recognize the fire? When I type "adb devices" there are no devices present.

Sorry again for being annoying lol

I've got python 3.4.2 installed. Which version would you recommend?

After some researching, people have said that python doesn't work very well on Windows 10, which is what I'm on right now.

Hi jmz,

I have a question here- all that was in your ZIP file was the cublock.py file.

Are we supposed to use this with the rest of draxie's tools in the HDX thread? If so, I was able to get an 'unlock.img' file, but nothing called 'unlock.signed'

maybe you didn't upload all the attachments we needed?

either way, thanks soooo much for your work !

sorry, with that tool you only get the unlock.img . I need to correct the post

In my linux box 'cuber' module, required by cublock.py, is not installed; is this the correct source? https://github.com/benesch/cuber

One more question: I forgot to block OTA update so my HD6 updated to 4.5.4, loosing root permissions. What I should do? Need to wait KingRoot supports the new software version or can I proceed to unlock bootloader and install twrp? Or could install, if available, a 4.5.3 recovery through dd? Very thanks.

I sense many roms being ported very soon...

grotz497 · Jun 9, 2015

Sure hope so!

I used the tools (cuber) in this post:

Need more info: Your computer OS, tablet device model (Settings>Device Options), Fire OS version (Device Options>System Updates). Tell exactly what happens when you run: adb reboot-bootloader.

These unlock instructions are for Fire HDs (4th gen). You need a fastboot cable for KFSOWI. Try G+ KFSOWI modding.

I am new to the tablet scene. This is my very first tablet. I would like to root the device and install custom recovery and hopefully custom Rom. Is this the first thing I do or should I start somewhere else?
