Liteon 811s Region Locked

I have changed the region on my Liteon 811S DVD Writer too many times and now its locked. Is there anyway of unlocking it ? I have tried updating the firmware to DR8HSOP - from DR8HSOE but it did not unlock.

Can anyone help ?

Many thanks

Use LtnRPC found in the LiteOn tools guide in my signature.

my drive has been unlocked - thank you so much Ssseth
