My mini 2 fell in a lake for about 3-4 mins.
I quickly put it in a bag of rice for 4 days.
Changed the battery to a new one.
Turned it on.. and it worked ! I flew it for 20 mins and all good.

My problem is when I plug the drone to charge the battery.. I get a red light blinking and then nothing. The (new) battery doesn't charge.

I took it to a repair shop and they cleaned the parts. Same problem. I'm offered to buy a new board (around 190$) + repair time which should come at around 250$ (Canadian).

I'm wondering if anyone got a similar problem and if there's another way around.

I was thinking to getting it back and try to update to the laytest firmware.. I don't know if that will fix it.

Thanks.
