In case anyone had the same quirk I was having with both the water effect AND stock JB lock / unlock sounds going off, just navigate to system/media/audio/ui and change the following two items:
- TW_Unlock_Glass.ogg to TW_Unlock_Glass.BAK
- TW_Unlock_Puzzle.ogg to TW_Unlock_Puzzle.BAK
Works as it did before on stock TouchWiz
Also, glad to say that my worries over the kernel and theme in the 2nd post were for naught, everything works fine so far, flash away! Hell, Wallet even works as it should.... Still have to get all the 4.2 GApps on it though, but it's working well so far!
