I had successful update but camera would never connect and I had a brick for a camera and yesterday I called and after many, many attempts, I finally got someone at DJI to answer and when he had me turn everything back on, mine connected for the first time since update while on phone (go figure) and worked fine.......at that time (I was at work). He told me it wasn't all to uncommon and it is good news that the update did go through as it should have if it flashed yellow and then flashed green and sounded like it was fixable. Since mine worked while on the phone after a lot of tries the night before doing resets and I even did a Bind procedure but no luck originally before I got a person on the phone. It took a good while, but they did answer.
Problem is that I tried to test fly last night and it started and did great but noticed that the screen shot on iPHone was a little bright. I took a photo at 60 foot and it got so bright on the screen that I couldn't not fly by the screen. I took another photo and then the screen went black and after multiple photos testing it, I never recovered from the Black screen. I got aggravated and felt like I could no longer depend on the entire thing and I am using it for my work and if I can't depend on it, I had the option of sending it back to Amazon since I only bought it a couple of weeks ago, so I am doing that. I boxed it up and sending it back today and they are shipping me a new one. DJI probably can help if needed, but I didn't want to let me time run out before replacement of the Phantom Vision, so I opted to just get a new one right off the bat. Kinda gun shy about doing another update on the firmware on my next version but looks like most have had no issue. Mine worked while on the phone after everything was turned off and had a good nights sleep and woke up refreshed and worked fine it seemed until it took a nap for the rest of the day and then acted up again yesterday evening when testing it.
There is another thread with my experience in it that can be read, but most all are having good luck with theirs. Figures I got stuck! Wished mine wouldn't have worked when I called DJI so that I could have proceeded to get a fix from their support guy and could have advised further here for the others that have a brick hanging from their Phantom. Sorry, Wish I could have helped, but having mine replaced.
