Don't even worry about it at first! It's safe to assume that the bird was working when it was shipped from the factory, so charge the batteries, download Go for you phone or tablet, read the manual, then start up. You'll have to go online through the Go app to get the bird registered and activated. Then go through the start up routine and take it up 10-20 feet to make sure everything is functioning properly. If so, fly it for a while to get familiar with how it works and then start thinking about how/if you want to update the firmware. Lots of posts here on a lot of peoples' experience with different Firmware versions.
