Hi JArgoWareS,
Thanks for posting in the Roku Community!
We appreciate your patience regarding this matter and value your feedback. We understand that you are facing an issue with your Roku device and we're sorry to hear about the experience that's not what we aim for.
To narrow down and resolve this issue, can you please verify how are you powering your Roku device? Is the device plugged into the TV USB port or is it plugged into a wall outlet? Have you already tried performing a factory reset on the device to see if you can get past the loading screen? As a last resort, if you are still experiencing an issue, we would recommend disconnecting your wireless network, then rebooting your Roku device to see if your Roku device is experiencing the same issue. Once the device is getting past the screen, try reconnecting your wireless network.

We look forward to hearing from you and looking closely into this issue. Thank you!

The device is a Roku Ultra 4640X and is powered by the plugin brick. I had the device using wired to a AT&T fiber optic internet connection. I tried all of the recommended resolutions, even resetting to factory settings. To no avail. Still stuck at the 100% point for an hour. I decided to leave in connected overnight, and low and behold, it said it installed the update. The time of the install indicated it took over 5 hours. Updating the channels after relinking the device had it stuck again for over an hour. Left it and came back sometime later and it finally had the task finished. I have a 4662X, a 4800X, and a 3960X. They had no problems updating to the version 12 software and did it over Wi-Fi quickly. The unit (4640X) that has the issue taking so long has another problem. It will connect to the Wi-Fi, but not make an internet connection. When using the wired connection, it does connect to the internet successfully. If I were to speculate, I would say the 4640X is having Ethernet packet loss issues in the software or firmware.
