I am needed help with my xbox please

I softmodded it last year then one night I saw you could go back to the xbox theme. Well, I did and when I did it looks like it took the mod off the xbox. I am scared to try the mod again because I blew one up that I did not know was already soft modded.

all the files are still there, but I am unable to play dvds or the game I have saved on the xbox. so I am wondering if when I switched back to the xbox theme did it take off the softmod?

if it did am I ok to mod it again? I miss well the whole family misses using XBMC and now I am using linux mint with a file server running it will be great to have it back up and running.

tia for your help

How did you softmod the console originally? How are you confirming your files still exist on the HDD? How did you "go back" to the original "theme" (er, "dashboard" I think you mean)?
