When the update fails to complete here are some things that some people have found to work for them. They may not be universally successful, but they are at least worth a try
Easiest to try, so try this first: Restart your router, even if other devices on the network are not having problems. When your router has completed its startup, try repeating your Roku setup.
If you are powering your Roku by plugging into the USB port on the TV, try powering from house power via a USB power adapter, as some TV USB ports don't supply enough power to drive a Roku reliably. If your Roku didn't come with an adapter, or if you don't have a Roku adapter handy, another USB power adapter you have from another device should work as long as the fine print on it says it outputs at least vac at a minimum of 1 amp.
Try using a different WiFi network to do the update - perhaps via a WiFi hotspot on your mobile phone or by taking it to a friend's house - and see if it will complete the startup. If successful, then redo the WiFi connection to use your intended WiFi network via Settings > Network > Set up connection. Why this works, when it does, I haven't a clue.
THIS WORKED FOR ME WITH MY Roku 3800R Streaming Stick from 2018:
1) I pulled the USB power cable from my SCEPTRE's (a nice, DUMB TV) USB port, and used the adaptor to plug into an AC outlet. Didn't change anything.
2) From the useless, spare "Roku / Time" screen displayed after failed updates, I was able to access the
UPDATE & RESET SECRET SCREEN:
HOME x 5
>> x 3
<< x 2
Tried "Cycle software update server" gave no feedback, so dunno if it did anything…also did the similar option just above it: "Cycle Streaming Store server" again, no feedback. After that, I selected "Update software"…don't recall whether I had to exit the screen, or if it just began doing its thing…was skeptical anything would work…it began downloading the update just the same as many times before, but THIS TIME, when it got near 85%, the "progress wheel" appeared for maybe one minute, then TV powered off & on, going through the similar system update machinations…often with no feedback & seemingly no change to the message on screen…I resisted the temptation to interrupt the process…and VOILA! It successfully did SOMETHING…couldn't really tell whether it updated the system or not (doesn't display enough decimal places where I looked, and didn't want to press my luck and break something), but at least I got back to the home screen and was able the use the Roku again…
