John, I was able to run the upgrade tool, it went trough, it downloaded the firmware and once done the lights started blinking then I shut it down just like your instructions, but I see no changes, still has the firmware it had before, the firmware that does not detect CIS or rechargable cartdriges.
My printer is an XP 211
OD13D2 serial s69k107371
Does your program actually downgrade Frimware?? I know that OD13D2 DOES NOT detect CISS that's why we need to downgrade to another older firmware. Because it doesnt seem like it did anything. And of course I can't tray again because its telling me the code has been used.
