Fire TV 1 Rooting, Recovery, and ROM Guide: Dirty Cow with blown eFuse Method

< Back to Fire TV 1 Software Version Selection

WARNING: Several people have bricked their device by following this particular guide for devices running 51.1.4.1 thru 51.1.6.3. This is the one and only rooting guide on this site that I have not personally tested. Because of this, you should seriously consider letting your device update to version 5.0.5, as the next paragraph suggests, and root using the method for that software version.

The Fire TV 1 running software versions 51.1.4.1, 51.1.4.2, 51.1.4.3, 51.1.5.0, 51.1.5.3, 51.1.6.0, 51.1.6.1, 51.1.6.2, and 51.1.6.3 is rootable, but because your eFuse is blown with those software versions, you will not be able to unlock your bootloader. An unlocked bootloader helps you restore your device if you brick it in some instances, but it’s not necessary to root. Since you can’t unlock your bootloader anyway, it’s best to update to version 5.0.5 (Build 537174420) if you can to make the rooting process easier. Let your Fire TV start downloading an update and if it begins downloading version 5.0.5 (Build 537174420), allow it to update and then follow this guide. If it begins downloading any other software version, then pull the power to stop the update from downloading, and follow these steps to root:

  1. [Optional, but recommended] Block updates using method 4 of this guide.
  2. Root by following this guide.
  3. Block updates using method 1 of this guide.
  4. Install TWRP custom recovery by following section 2 of this guide.
  5. Install the latest pre-rooted ROM by following this guide.

    ***ATTENTION*** – Following this guide leaves my device dead!
    May be because I had 51.1.6.1 and came on step 4 (how-to-install-twrp-custom-recovery-on-a-rooted-fire-tv-1) accidentally to section 1 (“Fire TV 1 on 51.1.6.3 or older”) on path…

    … trying to downgrade to 51.1.0.2_user_510058520. After this the box doesn’t even switch on.

    I don’t think you can install TWRP on a device which the bootloader is not UNLOCKED, as per http://www.aftvnews.com/how-to-fully-unlock-the-amazon-fire-tv-bootloader/

    I may be mistaken but the above guide may perhaps brick your FireTV1 upon installing TWRP as per above poster.

    Please be careful

    This procedure does in fact brick your FTV1. I’ve done it and had to buy another and start from scratch again. Will update on how it should be done as I have another FTV1 with 51.1.5.0 on it.
