Epson C5790 Printer Firmware Issue
I have an Epson C5790 printer that I tried to chipless, but encountered an error during the firmware installation process. The printer now displays a black screen with the message program upgrade/recovery mode MAIN in white letters.
Troubleshooting Steps Taken
I have attempted to revert to the original firmware downloaded from the official Epson website, as well as intentionally corrupting the firmware installation process. However, the printer continues to display the same error message even after reinstalling the firmware multiple times.
Request for Assistance
If anyone has successfully resolved a similar issue or has any suggestions, please share your insights. Additionally, when completing the firmware update, what information is displayed on the final screen of the LCD?
Additional Support Needed
I have tried loading eeprom data afresh, but have been unable to recover the chipless mode using the recovery code. Has anyone encountered and successfully resolved this issue before?
If you have any helpful information, please reach out to me through a private message. Thank you in advance for your assistance.
