I just got my code for the wf 3733 and after successfully flashing the correct firmware, I activated it but says wrong id code.
Do I need to take the cartages out..? Seen in instructions something about putting them in, but not taking them out.
Hear is a picture, I have tried several time, sometimes when I click activate, it seems to do something and says some read erro but most time does nothing but say wrong code.
Also when I copy the code from the email it has a extra character at the start the black dot, I have tried with and without the dot.
