Xbox jtag reset glitch community app deleted?

I got an xbox 360 slim with a jtag reser glitch since yesterday. On the 2 tb hard drive there would be more than 1000 games on it. I deleted some of them that were duplicated.

I deleted a community app which I thought was an Xbox live acarde game and Aurora no longer starts.

Is there a way to reinstall the file I accidentally deleted?

Since nobody else answered my question here.

I answer them myself.

I simply downloaded Aurora again.

Then I went through them folder by folder and compared the files and replaced the deleted files. It worked wonderfully.

Aurora starts again as before
