Is it still under warranty? Fitbit has been amazing about replacing products with defects. I am guessing that you have tried leaving it plugged in to the charger. I know that I have a few other devices that if the battery is 100% drained, no lights will work until it regains a certain amount of battery charge. I hope you are able to get it to work. My other suggestion would be to contact fitbits customer support. I have called and chatted with the fitbit support team in the past and they were extremely helpful.
Of course for my issue, right after I posted I tried one last thing, resetting my alta, and it synced right up. Seems like if a sofware delivery is going to require a device reset, they should give the users a heads up. I have wasted a good amount of time trying to fix my issue. Not to mention stressing about device compatibility which turned out to be a complete non issue. Technology can be so helpful and frustrating.
