VABS recovery without prevabs

As mentioned in the title, the customer wants to perform recovery using only the vabs ​​dat file without prevabs. However, to my knowledge, starting with vabs ​​4.0, the recovery flag in the dat file has changed to a damping flag, so it cannot be executed using the same method as in vabs ​​3.0. Could you possibly tell me how to perform recovery using a dat file in vabs ​​4.0 or 4.1?

Please read VABS 4.1 manual section 6.
