John_Admin 388 Report post Posted May 17, 2019 If You can't make firmware downgrade by WIC utility - it means Your printer has newest Main board version.Epson made some changed in new main board. The solution in this case is here:Use Activation Keys and License.exe application for P607 - http://www.2manuals.com/product_info.php?cPath=107&products_id=1850 Share this post Link to post Share on other sites
