I have a XP241, I have adquired the unlock lincences, but it doen´t works.
When I try to Activate Online, I receive a connection error, to verify usb port, firewall and internet connection. But its all ok.
The firmware was already updated to the version MF07I3. I have tried first using the printer in setup mode, so I have found an answer regarding XP241, where you indicate to do it on normal mode, but it doesn´t works anyway.
I have deleted all of other printers from my computer, including the XP241 drivers and reinstalled the 241 drivers.
Tried to send the MF07I3 firmware by normal mode and config mode, changed the usb port, changed the usb cable...
