Hi, I downloaded WF4730 firmware and activation software. When I tried to update my printer in normal start it would not detect my printer, but if i put it in program update mode it will, I tried to proceed with the update in program update mode which will go to 100% and show Finished on my printer screen but when I move to activation step it will not show again. The firmware doesn't seem to be able to flash my printer as the firmware version does not show CM99Z9 after update. Please help.
