WARNING!!! WARNING!!!!! I have the 32 channel hack....was waiting to upgrade my firmware until I learned more of what people were saying...AND I THOUGHT I LOST MY P4!! I upgraded tonight...batteries and all. I HAD the channel 32 hack enabled using channel 31 and low and behold I got about 3000+ feet out and my tablet FROZE (Nexus 7)...then REBOOTED!! NEVER DONE THIS BEFORE!! I tried to remain calm....activated RTH and kept contoller pointed in proper direction and waited for tablet to boot....NEVER did connect again after I started DJI Go app, BUT i heard it above me finally and breathed a sigh of relief...thank God I had set all of the settings after they got returned to default and my RTH was high enough. WTF!!! REALLY!! I am pissed....I had no issues BEFORE the upgrade and now this happens!! Please....I have lost ALL faith now...could be because of the hack being used at the time. PLEASE HELP!!
