khanmak 0 Report post Posted February 23, 2023 I have an Epson C5790 printer that I tried to chipless, but when I installed the firmware with the printer turned on normally, before it finished it gave an error and turned off. Now the printer is left with a black screen that says in white letters "program upgrade/recovery mode MAIN". I have tried to put the original firmware downloaded from the official Epson website, I tried to corrupt the firmware by disconnecting the printer before the end of the installation so that after meje put the new firmware, I tried to put the original firmware and the chipless and always finishes the installation but when I turn on the printer always remains with the message "program upgrade/recovery mode MAIN".
