RV50 router is not updating to 4.15.3

I have a router with version 4.14.0. I am trying to update to 4.15.3. It has failed to do so twice. It is not giving me any errors. I cannot find any info if I need to upgrade to a lower version before I go to 4.15.3.

Any help or suggestions?

Nevermind, I didn’t see where it asks if I want to update radio firmware and it will not continue until respond.
