Can you be more specific? 5.3.02 isn't right. This site has both 01.01.0030 and 01.02.0040: Phantom 3 Standard - Jogjasky
But I thought the Phantom would prevent you from downgrading firmware, could you explain in more detail what you did? Were you having the same NFZ issues? Do you have a STANDARD?
Ed . . . sorry I tried to post firmware from memory (#fail ) I should have said go back to v1.5.0030 . but this isn't for the standard -- my apologies. I don't know why I can't fly with the latest firmware vs v1.5.0030, but I know it will break contact with the ground (with v1.5.0030), which is why I bought it I dont know why the BETA processess isn't working like 'its suppose to', but its frustrating no doubt !!
