I have DVPSR400P/B dvd player with region code 5 Help me to make it region free
With Sony DVD players, it´s not possible to make it region free by simply using an unlock code. The only way is by doing a firmware hack. Doing this can also void your warranty.
I myself have a Sony DVD player/amplifier, which my 5,1 surround sound is connected to. What I´ve done is purchase another cheaper DVD player whose region was unlockable, which in turn goes into my Sony DVD player.
If you´re adamant about using a firmware hack, you should be able to find further information on the web.
