I lost my phantom in the sea saty sea and i took of the battery but that was after 10 min lost in the water any clue what to do next ;;;;;and i rinse it with tap water

Buy a new one as yours is almost certainly beyond saving.
Salt water is death to electronics.
You can salvage the props and SD card but that's about all.

Yep....it's toast.  Break out the credit card.  Sorry for your loss......but....what happened? How did it end up in NemoWorld?

Something unexpected happened what exactly i don't know but just lost control over the sea and saw it capsized and then into the water

Hello sir, really sorry to hear about that. If you are not sure the reason why it lost, please sync your flight record through DJI GO APP and then send an e-mail to support@dji.com, and provide the info when it lost and your DJI account (it's an e-mail address), the flight records will be analyzed.
