I have an issue with my P3 Pro, basically when I connect it with the USB to my PC it connects for 5 secs and then disconnects for 5 secs then back again indefinitely, the same happens with my SD card, I can't update the firmware as I suspect it disconnects the SD card every few seconds too. When the SD card is in with the downgrade firmware(card all formatted, firmware saved on the card for downgrade following instructions) the camera status flashes green for 10-20seconds then starts flashing red-green for 10-20 seconds and then back to flashing green, when there's no SD card inside it flashes green 10-20 and then turns to flashing red for 10-20 secs and then back to green indefinitely. Does anyone have an idea what's going on, been reading 4 days now and have absolutely no clue.
