It is necessary to remove the casing from the 4K and a heatshield.
This is a fairly simple process and if you are careful there will be no damage, but it will void the warranty.
Note: If you do not follow all the steps carefully there is a possibility you could damage it and maybe brick it.
I will accept no liability for this.
- A Firestick 4K. It is important to have this already setup with your Amazon account configured (and if you prefer, with any apps you want installed). Do not do this with a new, unconfigured 4K.
- A Laptop or PC.
- A TV or Monitor.
- An old credit card (or similar piece of plastic) for removing the casing from the 4K.
- A small flathead screwdriver or similar (plastic would be better) to remove the heatshield, though it may be possible to remove it without this.
- Some tin foil (aluminum foil) or thin wire to short a point on the firestick 4K (do not use anything harder as it is possible you will damage components on the 4K).
- The patched version of Linux which is packaged as an ISO than can be burnt to a USB stick (or a DVD should you prefer).
The latest version (fireiso-1.0.0.iso at the time of writing) is available here:
- A method to burn the ISO to a USB drive. I used Rufus (other apps may work but I had best success with Rufus).
- The exploit code that needs to be run from within Linux (kamakiri-mantis-v1.2.zip at the time of writing).
Download the below once booted in Linux (or visit the original xda thread mentioned above):
kamakiri mantis v1.2
- Magisk to root the 4K.
The version I used was here:
