That's what I thought, this is the page for DJI Care Refresh binding.
There are 2 different types of binding.
OP, are you not looking for information on whether the drone is bound to another DJI account?
I agree, the crash most likely did some damage to the boards or chipped some solder for sure I would shop around the area for a drone person for sure If I knew of one in your area I would let you know...sorry.
