Hi, I am using a Flipsky 75100 (the older version) and I have paired it with a 2800w hub motor. I run the motor detection and setup input, however when ful throttle the motor makes this weird noise like some is hammering it. For the hall sensors I connected them correctly.

Don't know if it has anything to do with the sound/issue.
But looking at the video it seems that your motor/shaft is not tightened all the way. Nut rotates when accelerating and braking.
that is true, the motor vibrates extremely thus the nuts gets lose. I have tried many different parameters it is still not working.
True, the motor vibrates so much that the nuts get lose. I have tighten them really good, but the motor vibrates.
The motor axle has to be super tight in the dropouts and not move even a single millimeter under load. If it does like the way it is now, this will first destroy the dropouts, then axle, then the motor wiring once the axle gets so loose that it will spin in the dropouts. You'd be lucky if that happens when you are not riding on this vehicle, otherwise, you risk getting injured.
It also looks like you are using duty cycle control mode for the throttle that causes the motor to jerk like that from the start rather than smoothly increase speed. You want to make sure that you use current control for the throttle.
