android terminal emulator problema

[DanitoMarzovito]

Devo scrivere questo: rm / efs / Fabbrica App / keystr
rm / efs / FactoryApp / FactoryMode
echo-n >> ON / efs / FactoryApp / keystr
echo-n >> ON / efs / FactoryApp / FactoryMode
chown 1000.1000 / efs / FactoryApp / keystr
chown 1000.1000 / efs / FactoryApp / FactoryMode
chmod 0744 / efs / FactoryApp / keystr
chmod 0744 / efs / FactoryApp / FactoryMode


quando vado per edigitare la seconda riga, l'emulatore mi dice "non found" come posso fare?
