All new WF-C5710 are getting the CU10L3 firmware and we are not able to get INKCHIP running. I saw that there's a new inkchip version for C5790, but not for C5710. Are you going to release a update soon?
PLEASE!
I also tried to update the firmware using both download firmware mode and normal mode.
Just after buying the printer and before initialize it I installed inkchip firmware and restart the printer and I got a scanner error and I could not use the printer.
As far as I read it's about new components in scanner's printer.
So I reinstalled (downgraded) original firmware CU10L3 and now I'm waiting for a new version to work.
HOPE you can solve it soon.
