Bearing in mind it is slow, if it doesn’t progress beyond 0% then from my understanding that may mean you unfortunately have the patched preloader.

So may may need to use the alternative method.

Bin it and buy a 4k, montoya 1st generation cannot keep up with modern apps and lag terribly. Not worth wasting anytime on if you ask me. Buy a 4k you'll get one for 30 quid just now on amazon

I'm having the exact same problem on Ubuntu 20.4, I tried windows 10 .bat script and I'm apparently missing a msvcr100.dll file. So had to revert to Ubuntu. Been stuck on 0% for half an hour now. Dunno what's happening.

I had twrp and couldn't get adb to connect, selected reboot recovery in twrp as it usually boots back into recovery. But instead I've bricked it like a proper donut.
I haven't any idea how to get round it, I tried doing the short again but it don't even appear "remove short and press enter" anymore, all I get is the handshake then serial protocol mismatch error straight away as soon as I plug dc voltage back in.

I am curious, what would happen if you run this on a non bricked device?

I have a Sloane that is currently on the newest 5.2.7.7 and I was wondering if I could use this method to revert back to something before 5.2.7.2.

Any help is appreciated.

Thanks in advance.

Why would you want to downgrade?

Try the new unbrick guide:

    This will help you unbrick a bricked FireTV 2. You must download the following:

    Extract all 3 zip files to the same directory.

    You must decide if you want to use unbrick.img or unbrick+ramdisk.img. Using unbrick.img, it should take about 30 minutes. Using unbrick+ramdisk.img it could take up to 2 hours. You can only use unbrick.img if you have an sdcard. If you have an sdcard, place ramdisk-recovery.cpio.lzma in the root directory of it.

    Run unbrick_firetv2.bat for Windows or unbrick_firetv2.sh for Linux or OSX.

    First, it will ask you which file you want to use, unbrick.img or unbrick+ramdisk.img. You must type the name of the image you want to use.

    Make sure the USB cable is connected and turn on the FireTV 2.

    Then it will start reading from the FireTV. Then it will prompt you with a warning:

    Code:
    No target file specified.  Is this a partition image?
    If this is not, DO NOT CONTINUE, otherwise press 'y' to continue.
    Write partition image? <y|n>

    Type a 'y' and hit enter.

    It should start writing. Eventually it will finish. If you put the ramdisk on the sdcard, make sure it is plugged in and power cycle the Fire TV. It should skip the bootmenu and take you straight to recovery. If for some reason the USB keyboard doesn't work, unplug and replug it. It should start working.

    I am in a boot loop. Goes to amazon white logo. Light on FireTV2 turns orange then reboots into custom recovery but it automatically starts trying to mount partitions (one of them is cache) and it fails on all of them. Then moves along to the white amazon screen again and repeats the entire process. I ran the unbrick.img and the problem persists.

    I'm currently in the process of running unbrick+recovery.img method to see if it makes any difference. Should it? Is there anything that I may be overlooking?

    I'm fairly sure that the reason this happened is from checking ALL the check boxes in the format/wipe section of the custom recovery. After that these issues happened. Does that mean permabrick?

    That's odd.... what do you mean it automatically starts trying to mount the partitions and fails? Where does TWRP show that? If you are getting the orange light it sounds like maybe you wiped your boot partition and it's not actually going to TWRP but stock recovery?

    Extract the boot.img from the prerooted ROM and place it in the directory with the unbrick files. Run handshake and reboot to get it to handshake, then run this:

    Code:
    mediatek_inject firetv2 YOURCOMPORT boot.img /boot -

    Replacing YOURCOMPORT with whatever handshake said your comport was. That should rewrite the boot image.

    When going into advanced wipe after running those 2 commands. I included an attachment with the error updates.

    UPDATE: So after reading "/dev/block/platform/mtk-msdc.0/by-name/cache is apparently in use by the system; will not make a filesystem here!" I figured I should try to wipe system. It worked! So then I tried to wipe data and cache. They both worked! I'm not sure if that means I'm home free but the errors are gone. I haven't rebooted yet though.

    Well try to reboot and see what happens.

    After using your cache.img the FireTV booted to TeamWIN. I selected Advanced Wipe ticked the cache and data then clicked the swipe bar in the bottom right to start the process. The picture shown is what happened next. I was still in the boot menu though. So I did it again received the same errors and clicked reboot. It warned me that I don't have an OS. Now I'm in the same boot loop again.

    I'm currently running your cache.img to get out of the boot loop again.

    Any other ideas for me to try?

    Connect via adb shell and run these 2 commands:

    Code:
    mke2fs /dev/block/platform/mtk-msdc.0/by-name/userdata
    mke2fs /dev/block/platform/mtk-msdc.0/by-name/cache
    2
    Okay, I followed those instructions. Here is the updated errors. They're similar but different.

    You're getting that after doing advanced wipe AND rebooting? That's not right...
