Notes for this version: He notes two things though. First off is this little gem, which we don't completely understand: "Should put index.dat (of firmware 1.50) in the root of the memory stick for on the "Software information" can read "1.50", but if it not put, it does not pass anything." More importantly, he also notes that you shouldn't use this on firmware 1.50, so just be wary of how you use this.
