Two days ago I started a firmware upgrade (with a 3rd party black ink cartridge installed) on my WF-4734. The upgrade halted in a “Maintenance Error” mode with a message that it “Cannot recognize ink cartridge. Try installing again.” No matter what I do, I can’t get out of that error mode.
After I found your web site, I downloaded your WF4730_FWF475TL_CM13I2.zip file, unzipped it and tried following your directions. I was not able to enter the �special Firmware Update Mode’. Every time my printer powered up, it came up in the “Maintenance Error” mode.
I tried running your EPFWUPD program and it recognized my printer but wouldn’t let me reload the previous firmware version, instead it said my printer's Status was "Downgraded (It cannot be Updated)".
I have since bought and installed a genuine Epson cartridge. I'm out of Maintenance Mode but I still can't get my printer to go into �special Firmware Update Mode’. Does the downgraded status mean my machine can't use your product to go Chipless?
