Sony DW-U18A question!!!

Does anyone here have a Sony DW-U18A DVD Writer? If Does, I need to know if it can be flash to a DL DVD firmware, and where can I find the firmware.... and of course if this process if safety too!!!

The Sony you have is the Lite-On SOHW812S as mentioned HERE. You can follow the guide posted HERE to change it to a DL Burner.
