Hi there. Having the exact same issue as: https://forum.2manuals.com/index.php?/topic/80626-error-when-trying-to-activate-wrong-id-readed-from-the-printer/ I notice you provided new firmware, different than the one on your site. Do you have a new firmware zip for WF4720? Thank you. Just bought my key and emailed you guys also.
