For Roku Express+, Roku 3, and Roku Stick had several issues trying to update each. I went to extremes and disconnected each and swapped the stick to my den so I could use my phone as the remote ( remote not functioning), Roku express from master bedroom upstairs (has repeater) to living room (added repeater due to signal drop -Frontier fiber line, and moved Roku 3 with larger capacity memory card for faster loading to master Bedroom since express was not updating by wfi. No express is not updating from 14.5.4 build 5934 to 5937. About ready to try with laptop. Suggestions?
