Nishioka, we're glad to help you.
The latest aircraft firmware for P4P is V 01.02.0304, may I know how you upgraded it? I mean through DJI GO 4 or Assistant 2?
What's the percentage it went? any error messages popping up on the screen?
Please try to restart aircraft and upgrade it again:

Make sure fast internet connection or Cell connection.

I had trouble upgrading with the DJI Go 4 app and tried multiple devices, but when I connected to a laptop using DJI Assisant 2 it worked right away with no issues.
