A very interesting question for anybody who locked their EEPROM messing with a wrong version of the software tool, ( like you and me...). Unfortunately I don't know the answer. The only way to know for sure is upgrading the firmware, and see what happens, but I'm very reluctant to do that, being a refiller. There's a fair chance that Canon has introduced sneaky code in the newest firmware versions, in order to prevent or make more difficult resetting the chips.I wish I could report that I was more intelligent. Having registered the 5204 tool, I learned I locked the EEPROM earlier by stupidly trusting a 5103 tool. This was not long ago, before I had the social will to ask for help in a public forum. (I am a younger, retired inorganic chemist and until now did not participate in any social media).
In the academic setting, email correspondence and a telephone call was everything. Clearly this is not enough today.
I am only mildly versed in electronics, so the crazy question becomes:
Does upgrading the firmware to the PRO10 unlock the EEPROM to changes useful to the 5204 tool?
