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

Hi. I have tried updating my tv and it would only get to 2% and then say that it couldn’t update and show error 008. I have called the Onn. Support team and they tried to help by telling me to factory reset the tv. That didn’t help and now I can’t even do anything on the tv because it needs an update. The Onn. Support team told me to try and get in contact with Roku through a phone number which I have tried but no one answers and I have left messages and no one call me back.
We want to look closely to see if there's anything else we can suggest to help. Have you tried restarting the Roku device and your router to see if you are experiencing the same issue? I'd also recommend trying to connect your device to an alternate network, such as a mobile hotspot.
If this issue is not resolved, please let us know along with any additional information you may have that would be helpful for our team looks into this problem. Kindly include the serial number of your Roku device so we can assist further.
