can i have some advice with this problem.. my p3 pro remote controller is not charging, after a few min. the led light stops
i tried replacing the batter but get same problem, and updated the firmware  anyone can help me with this

Seems like I saw a guy on YouTube that was exploring this exact issue. He was explaining what needed to be done to fix it the charging issue with the RC. You apparently have no problem opening up your RC if you changed the battery. You might try and look this up, but other than that I would suggest maybe to just bite the bullet and purchase a used one off Ebay or something. Or return it to DJI.

I believe the link below is what Richard was referring to; it has been posted before.

Did you replace your battery with an original battery?  If so where did you purchase it?

Hi sherne, sorry for the trouble you are having now, if the RC cannot be charged, it could be the issue of battery, the cable or the main board and so on, we recommend to send in for further evaluation by our technicians, please contact our support to start a ticket and send in.
