I upgrated my nslu2 with unslug 2.3 V65 6.8 but, now, I can't change the firmware. In fact, If I try to I receive an error: "Error: bad name or format". ...and my nslu2 does not recognise fat32 usb pen, after the first upgrade. What Could I do? Is There a way to erase all and have my nslu2 as new with the old firmware? Thank you guys!
