So I was initially using a Nexus 7 II tablet when I received the P3 a few weeks ago. As soon as I tried to update my RC to 1.3.20 I began to get error messages to update my firmware even though the app was telling me I had 1.3.20 installed.....I got tired of messing around with the apparent mismatch and decided to just invest in an Apple iPad Mini 2. As soon as I matched up the iPad with the RC I checked the firmware version and it says "unknown"! So, just for kicks...I reattached my Nexus 7 II and now, instead of giving me the error to update the firmware it says I'm running 1.3.20+! I can't figure this out. I feel safer flying with the Nexus tablet instead of the iPad. Any ideas on how to get the iPad to recognize the firmware on the RC?????
