I have a Epson xp-452 with MM1108 Epson version firmware and try to install this chipless firmware from: https://www.chiplesssolutions.com/download/chipless/XP452_FWH316TL_MM10I8_MM99Z9.zip
Put the printer in Update Program Mode and then update the firmware.
The printer receives the firmware and shows progress 0/100 to 100/100
Compares, Erase and Writes ROM data.
At final shows:
Finished!
Checsum B0BD
ROM Ver. 20.08.MM1018
Checksum2 B6D2
Rom Ver2. MM1018
In computer all is correct and shows finalized too.
I turn off the printer and when turn on it again and see the same Epson firmware with no update. Nothing changed-
What can I do to indeed update your firmware to the printer?
