Have you tried to upgrade by cable? If not that will most likely help you outGetting the same error when attempting to upgrade two of my RT-AC5300 routers to 386.5 beta1 from 386.4 which they've been running solid on for 48+ days.
Downloaded the beta twice just in case something happened with the first file, but same error. Also rebooted both and tried again with no luck
