XL Factory Reset - "System Exclusive transfer failed" - ?

I accidentally made some unwanted changes inside the OS of my Voyager XL, so I went for the Factory Reset feature… the first time I did it, it gave me a message that said “System Exclusive transfer failed”…

I turned the synth off and on again, and then tried the Factory Reset again, and it seems to have worked - it didn’t give me that error again, it just went back to browsing presets almost instantly…

Is that “System Exclusive transfer failed” error significant at all? Was there anything I was doing wrong at all?

The message “System Exclusive transfer failed” only comes when the sysex transfer was incorrect.
Did you transfer sysex data to the XL?
