NEC DVD ND3540A + region unlock

Alohas to everyone here.

I’ve found this site and downloaded the Dee’s N3540 1.WA RPC1 firmware for my DVD burner and then flashed it…flash was a success, but it didn’t make my burner region free…can someone help me on trying to get my DVD burner to change to region free? Mahalos in advance.

anyone :frowning:

Flashing only does not work.
