With the tires off, the noise is still there, so the tires shouldn't be the cause. This time I also took the rotors off. I used the OEM bearings and press the things myself by harbor freight tools.
I know the inner part of the bearing can't take the stress so I chose the metal plate which just fits the outer edges. I also did the method you mentioned several times. I could feel some vibration.
One more thing: last time when I finished the bearing changes, I drove about 1 mile with both tires obviously toe-out before alignment. Maybe this is the bad thing I did to the bearing and at least one of them didn't make it?

Try this to rule for certain which side its from and see if the wheel bearing is the possible culprit. If possible have a helper press the accelerator at the point the noise occurs to make sure.

1. Jack the car up with the front wheels completely of the ground and least 5 inches.
2. Secure the car on jack stands and secure the parking brake or chock the wheels.
3. Start the car.
4. After rechecking to make sure the wheels are OFF THE GROUND!!! Put the car in drive.
5. Both wheels should be turning at this point very slowly at least.
6. Carefully reach your hand between the turning wheel and fender and grab onto the coil spring with your hand.
7. If the coil spring feels smooth the wheel bearing is likely not the cause. If you can feel roughness, vibrations, or anything that isn't smooth through the spring the wheel bearing is toast.
8. Do the same for both sides.
9. Once verified press the foot brake and place the vehicle in park.
10. Shut off the engine.
11. Lower the vehicle off jack stands.
