I did everything on these instructions 5/6 times when I first got the maestro 4 years ago or so I got stuck on the same problem bye was able to get back to factory settings by pulling the power supply and while holding the power on button and plugged in power supply it put it back in factory modes, but now that process don’t work anymore I hate to sell this when I’ve never got to use it in custom mode. I couldn’t sell a product that’s not working I’m out $300!?! I contacted support about sending unit back when I was having problems with it it’s to late now but it never seemed to work right.
