By following this recommendation, will I need to buy an Activation key? I really didn't want to go "chipless", just downgrade the firmware to allow 3rd party print cartridges. What firmware version is FWF469TL.efu

Epson firmware update over the Internet today to 30.74.CL27J9 caused the printer to stop recognizing the installed 3rd party cartridges. ???? Downloaded WIC, bought a firmware key, put the printer in maintenance more, ran the update ( CL26H9) which said it transferred OK to the printer. The printer seemed to run the firmware update but when it seemed to complete it displayed a screen that said it still has the 30.74.CL27J9 Powered on/off a couple of times, but no change, firmware is still 30.74.CL27J9 and ink cartridges are not recognized. Tried to re-run the process but WIC says it's already done it. How can I fix this? Thanks.
