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

[ItsBabaYaga]

Good shout my friend. Shorting never gets boring! unless you can't find the short for love nor money.
Didn't think to try it shortless, thanks for the tip, will try it shortly

Were you able to short or use the mantis method on the Firestick 3rd gen (Sheldon) ?

I have a firestick 3rd gen on 7.6.3.3
Is it anyhow possible to install TWRP in it ?

Any way to downgrade software without shorting? Also, is the version the reason that it doesn't show up in fastboot devices when plugged in? Or is it the cable?

 

[Schnitzelbro]

How can i find a Fire TV Stick that can be unlocked? I had order 2 Sticks but the are on FireOS 7.6.3.3

Read this whole guide before starting.
This is for the 3rd gen Fire TV Stick (sheldonp) and Fire TV Stick Lite (sheldon).

NOTE: FireOS < 7.2.7.3 required

NOTE: This process does not require you to open your device.

What you need:

• A Linux installation or live-system
• A micro-USB cable

Install python3, PySerial, PyUSB, adb, fastboot. For Debian/Ubuntu something like this should work:

• sudo apt update
• sudo add-apt-repository universe
• sudo apt install python3 python3-serial python3-usb adb fastboot dos2unix

Make sure ModemManager is disabled or uninstalled:

• sudo systemctl stop ModemManager
• sudo systemctl disable ModemManager

NOTE: If you have issues running the scripts, you might have to run them using sudo.
Also try using different USB-ports (preferably USB-2.0-ports)

1. Extract the attached zip-file "kamakiri-sheldon-1.0.zip" and open a terminal in that directory.

2. Start the script:

• sudo ./bootrom-step.sh

It should now say Waiting for device.

3. Plug in the stick (powered off) and wait for the script to finish.
If it fails at some point, stop it and restart the process from step 2.

4. Your device should now reboot into unlocked fastboot state.

5. Run:

• ./fastboot-step.sh

6. Wait for the device to reboot into TWRP.

7. Use TWRP to flash custom ROMs, Magisk etc.

NOTE: Only ever flash boot/recovery images using TWRP, if you use FlashFire or other methods that are not aware of the exploit, your device will likely not boot anymore (unless you flashed a signed image). TWRP will patch recovery/boot-images on the fly.

NOTE: NEVER erase Preloader, otherwise you’ll hard brick the device and you won’t be able to unbrick it (since bootrom isn’t accessible).

Important information

Don't flash boot/recovery images from FireOS (FlashFire, MagiskManager etc.)

TWRP will prevent updates from overwriting LK/Preloader/TZ, so generally installing an update should work without issues (only full updates, incremental updates won't work).

For ROM developers there is still an option to overwrite these, which should only be done after thorough testing and if needed (LK should never be updated).

It is still advised to disable OTA.

special thanks to @Sus_i for all the testing and support.

That's fantastic news! I'm delighted you found a solution that works for you. Let us now proceed to flashing a ROM. It might be aggravating if TWRP reports that the Lineage 18.1 ROM is corrupted. However, it appears that you have already discovered the solution.

The zip file became corrupted during the transfer procedure with the Ubuntu LiveCD. Fortunately, you tried it again, this time using FTP, and it worked! The issue has been resolved.

Thank you for the update, and I hope the ROM flashing process now goes easily. Please contact us if you have any more questions or require assistance.

I know my issue is very similar to another that's already been posted here, but that post didn't get solved. Also, mine is kind of different.

I followed all the guide, until I got stuck on step 2. When I plug in the fire tv stick lite it doesn't get recognized by the pc, so it stays on "Waiting for device".
Also, the firestick turns on when I plug it, but the guide says to plug it in without turning it on. How do I do that?

Now, what I said until now is identical to the other post I was talking about earlier, but the difference is that when I use lsusb my pc doesn't find it.

I'm using Ubuntu on WSL.

WSL doesn't work, you need a machine with ubuntu installed on it, not a VM. Try an old laptop.

Is there a way to do it on windows instead of linux?

No

Nope, the program is designed for Linux and therefore you cannot run it on Windows. WSL is a VM, so it doesn't access USB devices the same way that Windows (host OS) does. You'll need a Linux machine, you can try booting Ubuntu on an old laptop and run the program.

In theory, WSL should be able to run the exploit if you use usbipd.​

Sir I need to know step by step procedure to reinstall stock firmware in Amazon firestick 3 gen. I am not a tech savy guy. is there any video or somehting visual that can help me do itr?

 

[lionleggend]

if you already unlocked that firestick you should run again the exploit to boot into TWRP and reflash the stock version linked here:

Go back to the original/stock ROM?

• Download the stock update.bin (sheldon | sheldonp) and flash it using TWRP

if you have a firestick 3rd gen, you must install the sheldonp rom.

 

[w1ll1m]

wrong thread.

 

[oldman20]

Omg, i received firestick sheldonp and it on 7.2.7.9. sadly, it mean impossible root it?

 

[Chris180206]

Yes, keep your stick connected to pc and plug it into your TV. (Although its not necessary, you can also use "adb devices" to check for connected devices)

When your stick boots into twrp, use adb shell to flash/wipe/whatever_you_want

Hey guys,
I'm not all that familiar with how to "use adb shell to flash/wipe/whatever_you_want"
Could you confirm, that I simply run adb sideload custom_rom.zip after the stick booted into twrp? Potentially adb sideload google_apps.zip afterwards?
Or is there any other steps or shell commands that I need to take?
Or am I completely on the wrong track here?

Thanks for a short info or any reference
Cheers,
C

Hi, I'm on update 7.6.4.6. Any possible way to downgrade?
