i need to know how to remove activation loc

Why do you need to bypass activation lock? Did you purchase a used phone that is activation locked? If you did, you CANNOT remove it. And if that is the case, return the phone for refund as the only person who can remove the lock is the person who put it on the phone to begin with.

If this is not the reason you want to remove activation lock, please provide more detail.

See - Turn off Find My iPhone Activation Lock - Apple Support for instructions. You will need to know the AppleID and password used with iCloud to remove it.
