My TV model is S535, and ERROR-008 will appear if it cannot be upgraded through the network. It cannot be upgraded via USB.
Now that I have successfully upgraded to the latest system, I will share with you my method.
1. https://tvupdate.roku.com download the system installation package corresponding to your TV model from the website and copy to U Disk
2. On the side of the TV, there is a small "reset" button, press and hold for 20 seconds, the TV will enter the recovery mode (at this time the TV looks like it is broken, but you can actually see all the codes you need)
3. Follow the instructions on the website where you downloaded the firmware to upgrade the TV
After searching everywhere to find an answer to this unsuccessfully and trying everything I could find, I finally had success. My tv is an onn. 75" and was giving me error code 008 right out of the box.
The fix: I did a manually reset by pushing and holding in the reset pin on the back of the TV while the TV was on. On this model it is located by the HDMI inputs. The TV resets and then restarts in recovery mode. I was then able to connect and update the firmware. The TV restarts and is ready to go.
UPDATE: Or apparently the post above me outlined all of this lol
Please help me fix mine
