[Advice] cannot change permissions with firm 2.0

I update to 2.0 without any problem and everythig seems to work ok, but i can't change the permissions of any folder, I used winscp, iphonebrowser, totalcommander, and i can't.

please help

i get this error:

Command 'chmod 0775 "IMG_0241.JPG"'
failed with return code 137 and error message
-sh: line 53: 57 Killed chmod 0775 "IMG_0241.JPG".

What are the errors reported when you try to change them?

i also tried running bbupdater on 2.0 but i got operation couldnt be executed, and after i unloaded the CommCenter i tried again but this time it returned an error saying "KILLED" in MobileTerminal.

i am also getting this error with winSCP

edit: well i used smartFTP and it worked seems winSCP just wasn't cutting it.
