The great rbox has done it again. He has just released a method to partially unlock the Fire TV’s bootloader. It’s only a partial unlock because it does not enable fastboot flashing, which means it requires that your Fire TV already be rooted. Sorry, but this release does not help those with unrootable Fire TVs gain root. What it does do is make the Fire TV a little more modding friendly, which will hopefully lead to even cooler mods in the future. For the time being, the most important thing to know is that an unlocked bootloader will be a requirement to installing future updates to ClockworkMod custom recovery. Starting with ClockworkMod version 6.0.5.1.4, your Fire TV will need to have an unlocked bootloader to install ClockworkMod for the first time or to install ClockworkMod updates.

Guide

Be sure your Fire TV is rooted and that you’ve read the section above to determine if you need to downgrade your Fire TV before proceeding with this guide. Download the aftv-unlock file from rbox’s XDA Post. The download link is near the bottom. Connect to your Fire TV via ADB Transfer the file you downloaded in step 1 to your Fire TV by running the following ADB command:

adb push aftv-unlock /data/local/tmp/

(Note: This assumes the file you downloaded is in the same directory as ADB, otherwise enter the full path to the file, like this:

adb push C:\full\path\aftv-unlock /data/local/tmp/ Run the command:

adb shell Run the command:

chmod 755 /data/local/tmp/aftv-unlock Run the command:

su

(Note: If this is the first time you’ve ever run the command su , a pop-up will appear on the Fire TV screen where you will need to select “Grant” within a few seconds before it disappears. If you miss it, then run this command again.) Run the command:

/data/local/tmp/aftv-unlock unlock If done successfully, you will see the following message:

Attempting to unlock…

All done! Run the command:

exit Run the command (yes, again):

exit

You should leave the aftv-unlock file on your Fire TV incase you ever need to lock your bootloader, which you do by running the command: /data/local/tmp/aftv-unlock lock
