Sony DDU-1621 / Asus E616P2 rip lock remove

can anyone help me find firmware to remove rip lock on either one or both of these drives:

Sony DDU-1621
Asus E616P2

any help, questions or possible solutions is appreciated thanks in advance!

Such a firmware does not exist for those drives. The DDU-1621 is actually a very fast ripper for pressed discs, it just reads burned discs more slowly.
