.. And now I don't know my lock code.

I found it earlier after someone cracked the pass for me, and it was slightly different to the one that the previous owner gave me. But I apparently changed it so it won't work any more.

Here's the old thread:

What can I do to recover my lock code, or at least boot up my phone without it?

I have a multiboot with NITdroid on, if that helps.
