Hi, @Jaymit.
Welcome, and thanks for posting here in the Roku Community!
We'd like to take a closer look at your concern about your Roku not updating after a factory reset.
In the meantime, try connecting your Roku to an alternative internet connection, such as a mobile hotspot, to see if it makes any difference.
For more detailed information, please visit this support FAQ on how to fix software update issues.
We are anticipating your prompt response.
All the best,
Emman
