    I have also asked for more info about flash programmers but got no answer. As an old timer radio amateur I think I would be able to build one if I got the necessary info which I sadly have not been able to find on the web. See this thread about the same topic and with links to a couple of commercial programmers intended for (illegally?) "rejuvenating" cars/auto mobiles. It seems the EEPROM chips used in cars and in Canon printers are the same family.

    I have an MG5550 with locked service mode but else functional. I also have a couple more printers of the same cartridge generation that are not locked and for which service mode operations are possible using service tool v4720. So I have got printers to experiment with, I only need some info.
