Hello, i need to know where i can find the firmware to my 'phantom 3 4k, the page of dji doesnt have the firmware, i try to upgrade by the IOS APP and i cant.
I wanna know what is the last firmware to my drone. Thanks.

The done should be upgraded via DJI GO APP connected, there is no need to download file from DJI website. Please make sure your WiFi internet connection is great as well.
Here is the tutorial for your reference to upgrade it:

Looks like the actual upgrade process is the same on the Standard as it is on the Advanced and Pro where the firmware upgrade BIN file is stored on the SD card.   Would have been simpler to have the user copy the firmware upgrade BIn file to the card rather than having them have to bounce between WiFi connections on their mobile device.
