[UNLOCK][ROOT][TWRP][UNBRICK] Fire TV Stick 3 and Fire TV Stick Lite (sheldon/p)

[Sus_i]

It appears that everything loaded fine, but I get a Hacked Bootloader message on the TV screen? Any ideas what I am doing wrong? Thanks in advance!

It's all fine.
At this step you need to run: sudo ./fastboot-step.sh
Then TWRP will come up next and adb devices will show a serial.

Thx for sharing.

Is there a hardware method that can be used on devices with newer fire os.

Thanks for the help! I have LineageOS flashed to it, but it's stuck on

Sorry, message sent before I finished. It's stuck on the LineageOS screen with the 'Start' button.

I tried...

The remote control, nothing happens, then I tried

ADB devices
and
fastboot devices

And nothing is found? How do I get past this screen?

Thanks for the help!

It's stuck on the LineageOS screen with the 'Start' button.

Common issue, take a look in the lineageOS thread...

 

[disco_y2k]

Thanks, I will check it out!

Just FYI I ordered mine on Amazon on Black Friday and it was able to be flashed.

 

[DiasAugustto]

I'll try on a newer device...

What version of Fire OS did your devices come with? Received with 7.6.1.4...

@DiasAugustto

Both came loaded with Fire OS 7.2.4.2 (PS7242/2907)

Please forgive me but I'm a complete noob as far as AFTV is concerned.
I followed all steps successfully, no errors and when I do ./fastboot.sh I get that's booted in TWRP.
I didn't flash anything (yet) because for the time being I just want root access.
But when I open X-plore on my fire stick it says "Your device seems to be not root"
What am I missing, how do I get root access?
Cheers,
Luc

 

[Sus_i]

how do I get root access?

As soon as you flash magisk.apk (renamed to zip) via twrp...

Hi, one question: can i use the original fire tv micro usb cable or it doesn't send data ?

 

[Wheresmycar]

I'm sorry for the super basic post, but I've lurked for many days and wasted more hours than I'd care to admit trying to figure out how to unlock and root a Fire Stick 4K. Out of the box, it's running Fire OS 6.2.8.1 (NS6281/3387) and I was able to prevent it from autoupdating during setup and also disable automatic updates through ADB. I'm now running FireISO as a livecd in a VirtualBox VM, but still can't complete the first step.

Running ./bootrom-step.sh responds with "Waiting for device" and this never changes. I have set the Fire Stick to automatically be connected to the VM and it appears to be connected properly, though the script never proceeds. I have also tried various combinations of powering it on before running the script and after. I have also tried running the second script, ./fastboot-step.sh. Nothing seems to make any difference.

Thanks in advance to anyone willing to point me in the right direction!

Edit: I was able to disable updates with the first two ADB commands in post #69, but "pm disable com.amazon.tv.forcedotaupdater.v2" resulted in "Error: java.lang.SecurityException: Shell cannot change component state for com.amazon.tv.forcedotaupdater.v2/null to 2". I had also run "pm clear com.amazon.device.software.ota" to clear the update that may have been downloaded based on another site I came across while trying to figure out what to do.

Edit 2: I bought the Fire stick a couple months ago, in case that makes any difference.

Edit 3: (in reference to the original edit) running "pm disable-user --user 0 com.amazon.tv.forcedotaupdater.v2" in adb shell led to the command working.

hello, i can't remove the twrp, i flashed the stock firmware but it still remains. I don't have a backup, can you explain me with going back with the stock recovery

FireISO is fine, your Sticks OS version too.
As you know, you can follow the sheldon OP guide, but only a kamakiri.zip for mantis will work.

Question is what state or process auto connects to the VM?
It's the first boot stage called preloader which needs to be connected, just at the same second as the usb connection... a mess doing this with a VM.

You need to flash a clean stock rom, wipe data, then boot 'hacked fastboot' and flash the boot image via fastboot (use/extract the boot img out of the stock rom).

now I'll try, when the stick starts it tries to upgrade how can I avoid it?

On your phone, disable wifi and data and then turn on your phone's hotspot. Connect your stick to it. As soon as it connects and starts looking for the update, press the menu+back buttons simultaneously (if the stick might still have internet access through your hotspot, you could also quickly disable the hotspot immediately before pressing this key combination). It will break you out of the autoupdate process and take you to the Voice menu. Pressing the back button will let you proceed from there.

I had downloaded v2.0.1, but haven't yet got to a step where I do anything with it.

The stick only connects to my computer (and then VM) as it boots up into FireOS. I have fastboot and adb installed on my (Windows) computer from when I rooted a phone a year or two ago. Can I use those? I haven't been able to restart the computer for some time because there are too many (non-fire stick) things that are open and ongoing.

To be honest, I still don't understand how to flash anything onto the Fire Stick, including how to even install TWRP on it. I can send ADB commands to the stick over wifi, but that's about all I've been able to do with it.

Download rufus, then write the fireISO image to an usb storage stick.
Press whatever key applies to your PC system (F1, F2, F8, DEL or something else) to boot the usb storage...

The stick only connects to my computer (and then VM) as it boots up into FireOS.

Thats the problem. If you use the fireISO booted directly, the bootrom-step script does a handshake with the first boot-stage 'preloader'
The VM is just too slow, without the handshake in-time it won't work.

Nope

Stop or pause all the downloads for a while
Jokes aside, if you keep the stick from updating, you can do the unlock anytime later.

TWRP gets installed via the kamakiri scripts and you can use it via adb usb cable connection or via usb keyboard/mouse if you get an otg cable.

is there a guide to flash the original recovery and return everything to stock?
