I changed to 241 within a few days of getting my OP-1. At the time, I was very concerned that something might go wrong with the update. I studied the directions carefully before doing the update, and everything went fine. However, I am worried, based on a few accounts I’ve read, that if something goes wrong during an update, that could “brick” my Op-1. I am not using it as a MIDI controller, and I don’t really care about tiny glitches in the graphics. That makes me wonder if I really need bother with the 242 update. That is, assuming the only real changes are the ones listed, above.
