noob question guys, I keep getting the "cant open" error for this one... I have already backread from the first page of the thread to know if I did miss something, but still the error persists....

what I did was this.... downloaded the file from my desktop... then unzipped it, then I copied the file from the zip to my N900 which is connected through usb on my desktop... I just copied it on the internal memory and not inside any folders whatsoever...

Now when I open xterminal, I first enter sudo gainroot since as far as I know it is how I can run the command as root... so after the sudo gainroot I would enter the command

sh OptimizeN900

and I would receive the error that I cant open the OptimizeN900...

any help guys? Thanks!
