How do you downgrade from 1.60 to 1.5.2?

Since updating to 1.60 I’m having issues with my jog wheels stuttering and now have developed an issue with my left play button becoming intermittently unresponsive so I would like to downgrade back to the 1.5.2 firmware as I didn’t have any issues with it.

My question is how do I do this as on the denondj site it says older firmware is unavailable at this time… Please help as I have a gig coming up

Just reinstall any of the earlier firmware versions that you downloaded since getting your Prime 4 in 2019.

You did keep them?

Haha yes yes I do keep them, didn’t even cross my mind I had them, top man many thanx fella

I’m looking for 1.5.2 computer installer do you have that by chance?

What firmware version are you running now, and what problems do you have with it (i.e. why do you want to revert)?
