How to downgrade from 7.9.2?

Recommended Posts

Hi guys,


I need to downgrade from 7.9.2. to some older version before big controlling changes on my LeapFrog48. When I put USB with 7.9.1 and older, console tell me that software is not compatible with this product.


Those software changes are not good for me, I missing simply adding palletes with holding buttons, extend from 10 to 30 submasters on page, intuitive and simply editing submasters...

Just so you know, in ZerOS 7.9.2 you can still update palettes and groups by pressing and holding their respective MFKs.

I'm sure you've seen the training video, but just in case you haven't the YouTube link below gives an overview of the operation changes of Solution, which also applies to your Leapfrog 48:


ZerOS 7.9.1 was for FLX and Orb consoles only, therefore it isn't compatible with Solution/Leapfrog consoles.


For Leapfrogs the software release before ZerOS 7.9.2 is ZerOS which you can get here:



The link is for FROG2 as ZerOS is what it runs, but if you run the USB creator and format a memory stick (preferably a Zero88 memory stick), and then boot the Leapfrog with the memory stick plugged in it will install the software.


Hope that helps, any queries let me know.


Kind regards
