I have a P4Pro that has No Video, the problem is in the RC, (tryied a second RC everything was ok) it connect to the AC everything works, but no video, it will not give you the advanced setting to change P4, P4Adv, P4Pro, I  think it my be stuck in the P4 mode, it is trying to update lights on the RC kept flashing like it is updateing but never stop, also when it just comes up it says, "init map error: UNKNOW"

I downloaded the apk file and put it on the rc, however, when i tap on it in the downloads folder it is not loading the apk.  I don't see a file browser native on the rc can you please let me know how I can execute the apk file to update the rc.
