I installed Android Terminal Emulator (Jack Palevich) on my phone, but when I try chmod 777 hello, it says operation not permitted.
The phone is running cyanogenmod 7 , and I assumed it's rooted.
You may have to use 'su' or equivalent to work as a superuser to run chmod...
You can try the attached file (it's a .tgz in a zip), it should have the permissions already set. You may have to extract using the tar/tgz with -p option to preserve permissions, but I wouldn't know. Maybe someone who knows what they're talking about might chime in
