Hello,
I just want to share my experience here. My printer is a WF-4630 USA, firmware GM01I8 01/08/2018. I downgrade to GM09GC 09/12/2016 chipless. Now the level of my ink is infinite!. I did not deactivate my antivirus or firewall what so ever. Everything was running smooth when the firmware was installing. I use a USB 3.0 cable.
Thank you!
