Downgrade tvOS 16 Beta to tvOS 15 on Apple TV HD [Tutorial]
Here is a complete step by step tutorial on how to downgrade tvOS 16 beta to tvOS 15 on your Apple TV HD model.
Downgrade tvOS 16 Beta to tvOS 15 on Apple TV and Skip Testing out Beta Software
tvOS 16 beta is now available for all registered developers and they can go ahead and test it out on their compatible Apple TV right now. However, if you want to downgrade tvOS 16 beta back to tvOS 15, you can do that too, but on the Apple TV HD only.
If you have installed the tvOS 16 beta and wish you could go back to the stable, public tvOS 15 release, you have the option to do that. But, it's possible only on the Apple TV HD as mentioned above. The reason for that is extremely simple - this model includes a USB-C port, something which which Apple removed with the 4K models, allowing you to connect them to a computer and downgrade to previously signed software.
First and foremost, you need to get hold of a USB-C cable that can plug into your computer. Depending on the situation, you might either need a USB-C to USB-C cable, or a USB-C to USB-A cable. One end needs to be USB-C as that is the end which will go into your Apple TV HD.
Once you've gotten hold of the cable, make sure you have downloaded the tvOS 15 firmware file required to downgrade. The current publicly available firmware is as follows for the Apple TV HD:
Save the firmware file to your desktop for easy access.
Step 1. Connect the USB-C end of the cable into your Apple TV. Check out the image below - the USB-C port is right above the HDMI port.
Step 2. Once the cable is connected, plug in the other end of the cable to your PC or Mac.
Step 3. Now launch either iTunes or Finder, whichever applies to your situation.
Step 4. Let Finder / iTunes detect your Apple TV and it will show up in the top left hand corner as a tiny icon. Click on it to reveal more options.
Step 5. If you have a Windows PC, hold down the left Shift key and click on the Restore Apple TV button. Mac users have to hold down the left Option key.
Step 6. Select the tvOS 15 firmware file you saved to your desktop.
Finder or iTunes will now extract the contents of the firmware file and then restore it onto your Apple TV. If all goes well, the iOS 16 beta downgrade process should be complete in about 15 minutes at best.
Once the installation of the tvOS 15 firmware file is complete, unplug the USB-C from your Apple TV, that's all.
