I did mine using the USB option. The firmware version I now have had only been released a few days before and I think before that it was the "public Beta" version. I primarily updated so I could watch the Avatar BD that I had read needed the update to play. I read somewhere that the people in Hollywood have been updating the DRM in the discs, which requires the updates to players to use the discs. So, it doesn't appear to be something that Oppo or other manufacturers forgot, but rather one they planned for, when they made the players firmware updating easy.
