I had my N73 unlocked today and was trying to modify the firmware to other version, everything went fine. After I updated the firmware, and was sending my backed up files back to the phone thru PC Suit, the phone restarted during the process and I unplugged the data cable after the reboot. Looks like the backup file re-flashed the firmware back to what it was before. and then after another reboot, the phone says: please contact the retailor, and doesn't work at all. Anyone has an idea I can use to get back to live? Cheers
You will have to call the retailer / network like the phone says. There is nothing (as far as I know) that can be done.
