[Q] get torch light back after installing JB??

Hi guys. How are you doing today?

So recently i installed jb 4.1.2 with multiview on my n7000 cuz i couldnt wait for Samsung to release it.
And everything is going perfectly fine. (battery now lasts much much much longer without charging. btw.)

And while im setting up themes and Widgets n stuff. I noticed that the "torch light" widget (which can toggle 3 different levels of light.)Has been replaced with the "assistive light" one. (which can only toggle one level of light which is the lowest one.)
And that annoyed me cuz i really liked that future..

And then i looked for a solution and i found the widget. downloaded it. But everytime i try to install it it will say: application not installed.

Any ideas on how to let it install??

Thanks
