In all cases a valid PIN or recovery key are required. Neither one of which the OP has. In addition the original volume has been overwritten, making recovery very close to impossible, even if the stars were properly aligned.
Agreed. BL is VERY good at what it does and a positive outcome for the OP is not likely. Recovery of the underlying info on the previously overwritten HDD by the OS install may be the only viable (even if remote) option.
