Do you have 3.41?
Did you put the 2 files in the /lib/firmware folder?
Did you put the "insmod /root/psfreedom.ko" and the "exit 1" at the beggining of the osso-usb-mass-storage-enable.sh file?

When it worked for me, it beeped 3 times. Also, do you have in another usb drive the "backupmanager.pkg" file?
