I just got a Pixi 7 from T-mobile on thursday, and there is a app on the Play Store called Kingo ROOT that I used to root my Pixi. So I used AGK Fire, and loaded it onto my Fire Stick, and ran it. I also had to put SuperUser on the Fire Stick. Now I have root, and disabled the Blacklist, and ota updates.

If this is known, and a guarded secret, please let me know :)

I was surprised that it worked :)

Yes I read that he used playstore version but when I try to get the playstore version I cant seem to find it, so went directly to the website of the app he used. I tried v3.1 and no success.

Tried all 3 versions of Kingo root. 2.5, 2.9 and 3.1. None have been successful in rooting 5.0.5.1. I can only assume the op is mistaken.?

Here is the exact APK I used. I also had to have the app "Rotate screen orientation " lock all apps in landscape mode, as kingo wants to open in portrait.

Below should be all you need...

You will need a mouse, or I just used "RemoteMouse" with my iPhone.

The first time I ran it, I thought it froze, and I held the center, Play-pause buttons to reboot the Fire Stick, and on reboot, I ran it again, and it worked. While it was rebooting, the progress bar started moving. SuperUser needs to be installed for it to work.

I Installed BusyBox, as uname isn't on the Fire Stick by default. I also did the Home button double-press disable as proof that it is on 5.0.5.1

Here is the exact APK I used. I also had to have the app "Rotate screen orientation " lock all apps in landscape mode, as kingo wants to open in portrait.

Below should be all you need...

You will need a mouse, or I just used "RemoteMouse" with my iPhone.

The first time I ran it, I thought it froze, and I held the center, Play-pause buttons to reboot the Fire Stick, and on reboot, I ran it again, and it worked. While it was rebooting, the progress bar started moving. SuperUser needs to be installed for it to work.

I tried it on a 5.0.5.1 Fire TV Stick, replicating what you say, and also failed. I did not need a mouse btw since pressing the center button on the remote starts the rooting process.

If you're not just trolling us, the only thing I can think of is that there's some sweet spot during the rooting attempt that the device needs to be restarted which you hit, since you say "while it was rebooting, the progress bar started moving." Do you remember what percentage it was stuck at? It never goes past 90% for me and then eventually says root failed after about 2 minutes at 90%. When the bar started moving while it rebooted, did it go past 90%?

If there is some sweet spot to reboot at, my guess is it's from when it stops at 90% to 50 seconds later. Around 50 seconds after it stops at 90%, the app tries to mount the system partition as writable and fails.

Tried the same with running su before and after kingo root and restarted at several times while it was at 90 % but had no luck until now...

I finally got root succeeded, the way I did it was as per op instructions. When it gets to 90 percent I waited around 45 seconds then held home/play pause down. Restsrted then re launched Kingo ?

    I Installed BusyBox, as uname isn't on the Fire Stick by default. I also did the Home button double-press disable as proof that it is on 5.0.5.1

    Tried it too with my second FTV Stick running 5.0.5.1 and it fails...

    DId you have the SuperSU app posted above installed? Did you launch it before/after? When it worked after the reboot, did it stop at 90% at all or did it breeze through?

    To those who have success with this, do you have Firestarter (or stopper) installed?

    Ive got firestopper installed, have not dome anything even instsll super user yet not had chance, will be blocking updates and using my normal root tools when I get them set up later.

    Here is the exact APK I used. I also had to have the app "Rotate screen orientation " lock all apps in landscape mode, as kingo wants to open in portrait.

    Below should be all you need...

    You will need a mouse, or I just used "RemoteMouse" with my iPhone.

    The first time I ran it, I thought it froze, and I held the center, Play-pause buttons to reboot the Fire Stick, and on reboot, I ran it again, and it worked. While it was rebooting, the progress bar started moving. SuperUser needs to be installed for it to work.

    I tried it on a 5.0.5.1 Fire TV Stick, replicating what you say, and also failed. I did not need a mouse btw since pressing the center button on the remote starts the rooting process.

    If you're not just trolling us, the only thing I can think of is that there's some sweet spot during the rooting attempt that the device needs to be restarted which you hit, since you say "while it was rebooting, the progress bar started moving." Do you remember what percentage it was stuck at? It never goes past 90% for me and then eventually says root failed after about 2 minutes at 90%. When the bar started moving while it rebooted, did it go past 90%?

    If there is some sweet spot to reboot at, my guess is it's from when it stops at 90% to 50 seconds later. Around 50 seconds after it stops at 90%, the app tries to mount the system partition as writable and fails.
