Firmware Downgrade on Epson WF-3640

Recommended Posts

I have a WF-3640 that Epson "sneaked" an auto firmware upgrade on and now my 3rd part carts show minimal ink, even though they should show full when replaced. This leads to low ink warning every time I try to print!

 

I have the original May-2015 firmware from the install CD (Recovery Mode version CB06E3_epson16126) which I need to replace Epson's Nov-2015 upgrade (Recovery Mode version CB30FA_epson17372).

 

Is there any plans to make the WIC utility work on the WF-3640 or did Epson pull something new on these printers to make FW downgrading impossible?
