Hey, I just bought a 'renewed' XP-15000 and a CISS set on ebay, but I can't seem to figure out how to downgrade the firwmare, and the chipless install failed as well.

Is this possible?

Right. Okay. I bought the license and it worked. It's just a bit deceiving. And the firmware update utility and wic reset were unable to help me verify if my printer would work with it.  Regardless, I've got it working.

 

If you have any changelogs for your firmware updates, could be nice to see
