Epson 7620 firmware downgrade - AD23K3 23/03/2020

Recommended Posts

Hi all the staff,

I have an Epson WF7620 that somehow accidentally got firmware updated in lately. We have a few users and someone might have done it accidentally. Now my CISS is no longer recognised and cannot print at all. I ran your tool and here is the current firmware, AD23K3 - 23/03/2020.

Just a quick question. Will your tool be able to downgrade the firmware of my printer and fix this problem? I heard that Epson has disable the firmware downgrade feature. I want to make sure that this will work 100% before I pay for the firmware key. If it does not work, will you give me full refund? Thank you.
