In short: If your ISP provides the update automatically, it is highly recommended. If you are attempting a manual "unauthorized" update, the risks often outweigh the benefits.

  1. Try the factory reset again.
  2. If the issue persists, attempt to flash the previous firmware file (if you saved it).
