10. Press 994
11. Press Magic Key (don't hold)

The remote is now programmed and ready to use, to make the BDP-S350 region free:

2. Press 1, 2, 3, 4, 5 on the oneforall remote. The 24p light will start flashing
3. Put the player back into standby with the Sony remote
4. Next time you turn on the player it will be region free for DVD playback.

The hack listed above apparently (as read in other forums) works very well on European Sony BDP-S350 Blu-ray players. I have tried it on a US BDP-S350 and although the player responds correctly (the 24p light flashes), it does NOT make the player region-free for DVD.

SONY BDP-S350 how to crack region codes from its own menu?
http://forum.videohelp.com/topic359858.html#1909910

You need the Sony remote AND a OneForAll remote. The remote used in these instruction s was the OneForAll URC-7040.

This link should explain how to find the "magic button" on a One-for-All (URC) or Radio Shack remote. Read on down aways for the description of advanced and discrete codes. That sounds like what mao141 is referring to in his hack for the BDP-S350.

1.7  What the heck is the magic button?

The term "magic button" is used throughout this document and in discussions about the remote.  The magic button is actually the star shaped "setup" button on the URC-7800 (learning) version of the Cinema 7.  On the Radio Shack 15-1994, the magic button is the green "P" button.  However, the older non-learning version of the Cinema 7, the URC-7200, actually uses the term "magic" for this button.

From what I've been able to gather, the older One For All remotes use the term "magic."  Consequently, "magic" remained in a lot of the documentation for the newer remotes.
