Could not stabilize my quadrotor after a crash

Hi guys,
Something really strange happened on my quadrotor, I can not adjust params to stabilize the quadrotor, all this happened after a crash. My quadrotor is really stable before the crash.
I have checked my ESCs and rotors, all devices seem fine, and I could not figure out where the problem is.

Could anyone help me?
Thanks for any suggestion.

Check the vibration. Are the props still balanced? Anything loose on the frame?
