Hi...I was updating new Phantom 3 Professional Firmware v1.9.60...but in the end...my aircraft keep buzzering non stop....so what's happening?

Can you be more specific. The aircraft will continue to beep.......but there are different beeps.
Did you watch the How to update your firmware video. It explains all the beeps.

Is the LED on the front of the gimbal solid green?  If yes update has completed.  Remove the bin file from the SD card.

hows the new firmware ? is it stable ?

Check your SD card and reveal hidden files, find the log file and see what it says, if it says "success", then the update is successful.  

If not, try updating the firmware agian.

Hello gquek84, have you tried to re-upgrade the firmware? Besides, you can post the hidden upgrade log here and these are the steps to find that LOG file:
1. Enable the option of viewing hidden files in your OS. Below are the websites where you can check how to show the hidden files in your PC.
For The Windows System:

For The Mac System:

2.Enter the root directory of the SD card, then find the hidden folder MISC and enter it. There is LOG folder in it.
3.The LOG txt file is under the LOG folder.

I tried this down load, same thing happened green light on and buzzing. Tried direct connection download with sim card in the P3A and next deleted everything of the root directory downloaded directly to the sim via usb installed the sim back in P3A same thing, had solid green led's on rear legs.  Did some check runs with props off all appeared to work OK, took the bird out for some low level flights (winds gusting to 37kn) appears to be working fine.When I checked the log that didn't show that I had done an update. This was on June 14.
cheers

Got it, only flew at home, have seen no issues so far.

I had this problem when I updated the firmware. I had two P3P and the other one had no problem updating.

I had this problem when I updated, I have two P3P and the other one seems OK (I haven't try it yet)

beep of hell
