I had a new firetv1 at version 51.1.0.1 and I got it rooted using towel root then followed OP's instructions. When the last command was run it rebooted however now it get stuck on the opening screen saying the the firetv is completely out of space and when I click on manage application the box to manage applications is empty. I pushed a rom to the SDcard folder in adb before I did the bootloader unlock but I don't know if that's the issue, it was only about 400 megs I also tried a factory reset but the out of space dialog still pops up with. I can use a keyboard to press escape to and it will let me go through the setup but after the opening video it just goes back to the beginning again. Anyone have any insight into why the out of space dialog box is showing up and how can I fix this? I ordered a cable to see if I can get into fastboot and if its truly unlocked but that will come in a couple days. Any help is appreciated thanks.
Known issue of FireOS 3. For a true fix Research updating from PreRooted FireOS 3 to PreRooted FireOS 5. For a short temp fix try: https://forum.xda-developers.com/fire-tv/help/hdd-space-shrinking-fast-firetv-box-t3518141

That temp fixed messed up my installed apps. They would not update or reinstall since the dbcache had been deleted. It's just a temp until your ready to upgrade to FireOS 5.

Thanks I'll try that when I get the cable, hopefully the bootloader unlocked worked and I can flash a rom. Unfortunately the way it is now it doesn't get to the point where adb connection is active, just stuck on the out of space dialog and doesn't get passed the opening intro video if I close it.

A to A usb cable came and found that the bootloader unlock worked and I was able to upgrade everything to latest preroot build. Thanks again for your help.

Hi
I've rooted my FireTv long ago (using towel root) and don't remember if I have CWM, how can I check it?
My SW version is 51.1.1.0_user_511070220
Also the download of the aftv_full_unlock file fails, can you please upload it again
thanks,
Moran

Replying to an old post but just in case anyone is wondering how to check what recovery you have installed:

adb connect 192.168.1.xx
adb reboot recovery

Hello @rbox
Is an unlocked bootloader possible with this, if I downgrade bootloader, recovery, system with a low voltage emmc reader to stock 51.1.0.2? And later, upgrade with an prerooted rom?
The ftv is on 5.0.5.1. Don´t know if it works due to efuse...

Edit: I read more about it, realize I can root the ftv, flash roms and twrp on it, but think no unlock possible.

    This is only for FireTV 1 running version 51.1.0.2 software.

    Unlike FireTV Partial Bootloader Unlock, this is a full bootloader unlock. fastboot flash and fastboot boot will both work. Of course you need an A to A USB cable to take advantage of it.

    This is a tool to run on your Fire TV that will unlock the bootloader and then reboot. For now, this requires root. Apparently, the IDs that are required for this can be gotten through fastboot, so if someone can figure that out, then brand new Fire TVs with 51.1.0.2 or older can be unlocked and have recovery installed before booting the first time. Please refer to the linked thread below for more information.

    As usual, this WILL void your warranty and I am NOT responsible for anything you do with this. Using this tool won't brick your Fire TV, but doing stupid things afterwards might.

    This was all code I had written for recovery before the partial unlock, just tweaked to be used in this situation. Thanks to http://forum.xda-developers.com/kin...bootloader-unlock-procedure-software-t3030281 for showing what needed to be encrypted.

    I have also published the full source at: https://github.com/androidrbox/aftv-full-unlock

    To use:
    1. Downgrade: You must first downgrade to 51.1.0.2. If you already have CWM installed, you can skip this.
    2. adb push aftv-full-unlock /data/local/tmp/
    3. adb shell
    4. chmod 755 /data/local/tmp/aftv-full-unlock
    5. su
    6. /data/local/tmp/aftv-full-unlock

    If after it reboots and you run 'adb shell' and you get a root prompt, it has worked.

    * Feb 16, 2015: The binary has been updated. The old version was unable to unlock certain Fire TVs. If you've already unlocked, you are fine. If it failed, this one should work.

    You can download it here

    Why run exposed? What's that going to get me? I run xposed on my bl unlocked phone, love it for what it does on my phone. Unless xposed is going to get me TV channels, which is what my FireTV is for....don't see a need. Still haven't heard a single "good" reason for root....js. See absolutely no benefit whatsoever.

    OK well good for you I guess? Are you looking for someone to explain the benefits of root? Or for someone to give you a convincing reason to root? Because you've clearly made a decision against it and are, for some reason, trying to convince others you're correct. I don't see why it matters to you that much, just let everyone else root in peace. ;)

    @Kramar111 To recovery your box you flashed new (updated) bootloader into your box, so now you have a rooted 51.1.4.1 but with a non vulnerable bootloader. With that update they burn an efuse so you can´t boot with vulnerable bootloader. So no, the full unlock won´t work for you.

    I am in a special case where I am already on 51.1.0.2 but I don't have CWM installed yet.
    So,should I install CWM,and then what do I do since I am already on the right firmware version?

    What special case? The ONLY mention of CWM in the OP is that if you already have it, you can skip the downgrade. Otherwise it says nothing of CWM. The first step is downgrade to 51.1.0.2. If you are already at 51.1.0.2, then there is nothing to do. Go on to step 2.
