![]() These points should be connected to the metal housing: Here’s a close up image of the points on the board, showing without any of the metal housing: These are the points we are trying to short in order to unlock the bootloader. This is part is a little tricky because the capacitors we need to link are really small. The short will put the bootrom in download mode allowing us to flash a custom image. We need to create a short in order to unlock the bootloader. The heat shield is held on by two sticky pads and should come off with little effort. The heat shield in on the side without the two square blocky antennas at the end. Use a small flathead screwdriver (a plastic one is preferable) or anything that you can slide underneath to unstick it from the base. The next part is to remove the heat shield which is blocking the small capacitors we need access to. There’s multiple connecting joints that should pop open without much effort. Opening the case is pretty simple use a tool like a small flathead screwdriver or pry opening tool (like this one) and place it in between the crevice to open it. It’s important to not that you should do this on stick that has been setup already with an amazon account, since I’ve read that it may not be possible to set it up correctly after it’s rooted.Īlso make sure to enable USB debugging by going into the Fire TV Stick: Settings -> My Fire TV -> Developer options -> turn ON for ADB debugging and turn ON for Apps from Unknown Sources Open Fire TV Stick case The sequence of steps we’ll be taking are the following: We install apps or move existing apps into the external storage to free up internal memory which should make the Fire TV Stick a bit more responsive. The Fire TV Stick has only has 8GB of internal storage which less than 5GB are actually available for use. The OTG cable is for connecting external storage to the Fire TV Stick in order to expand it’s internal storage. We’ll be connecting the points with a small piece of aluminum foil. The flathead screwdriver will be used to open up the Fire TV Stick to get access to the small capacitors on the board that we need to short circuit to unlock the bootloader. We need to make a slight hardware change to unlock the bootloader on the Fire TV Stick. We’re going to use Linux to burn a patched Linux kernel ISO into the USB drive which will be used to boot from and run the exploit on the Fire TV Stick. We’ll need the following items for this tutorial: We’ll only be going over the rooting process and optionally installing Arch Linux on Termux towards the end of this post. Block ads on the homescreen and in applications.Block Amazon auto-updates that remove features.For example, here are some of the things that can be done with a rooted Fire TV Stick: Unlocking the Fire TV Stick with root access allows us to install anything we want on it and circumvent the limitations of the stock operating system. Rooting the stick is possible thanks to an exploit uncovered by user xyz on the XDA forums and user k4y0z who created a nice package for executing the exploit. It goes inline so you don’t need to buy a USB hub.This tutorial will walk you through the high-level process of rooting an Amazon Fire TV Stick 4K (3rd generation of Fire TV Stick, released in 2017). They even made an adapter specifically for Fire TV sticks. They specialize in IR dongles and IR remotes. ![]() ![]() One of the few places I could find a reference was from FLIRC. I’m not surprised you couldn’t find references for adding IR to Fire TV devices with a quick search. There are actual TV sets such as “Amazon Fire TV 55” Omni Series 4K UHD smart TV". ![]() People can’t seem to wrap their heads around the fact a device can do both. Someone called me an idiot elsewhere because “Fire TV are Bluetooth”. One extremely strange code attempts to activate the voice remote feature but it just says the remote needs to be paired first. I’m at parity with the official remotes but there seem to be some unusual codes like one that can factory reset the Fire TV and one that I believe does a hard reboot. I’m very close to collecting all the IR codes in the correct format for the Flipper. ![]()
