You can replace Google’s software with alternative OS like open-source, Android-based LineageOS, and also GNU/Linux distribution like Ubuntu. Now, you will look for guidelines on how to unlock bootloader on Google TV.
The process is relatively simple as this section covered the same in brief. To unlock the bootloader, you must have a Google TV device manufactured before December 2020. Also, you should be running with a version of Google TV firmware that was released before February 2021. It is because the procedure will be applicable only for the mentioned update. It is better to check the Google TV’s manufacturing date on the box in which it came.
How to Unlock Bootloader on Google TV
1. First, remove your Google TV device from the HDMI port and hold the button on the rear while plugging the device into a PC.
2. Next, press down on the button to trigger the Amlogic USB burning mode and connect the device to the PC with USB-A to USB-C converter.
3. The unlocking mechanism communicates with the libusb-dev library, and it needs a 64-bit Linux operating system. So ensure that you have them on your PC.
4. Then, download the unlocker suite that connects Google TV to a PC running Linux with a USB cable. And run a shell script that executes the exploit chain.
5. Now, the modded bootloader will modify the /env partition and keep the device in a state where it is capable of ignoring the anti-rollback check and the signature on the U-Boot to declare itself as bootloader-unlocked.
