SCT X3 Tuner With Cracked Screen

I have an SCT X3 tuner that I have married to my 2003 V6 Mustang that I just found out has a cracked screen. I can’t view any of the info on the screen so I can unmarry it so I can use my SCT X4 instead. Does anybody know the button sequence that I need to do to unmarry it? I searched Google with no luck. I haven’t tried to contact SCT support yet, but they may not help since the SCT X3 is no longer supported.

Does anyone know the key turn sequence for the X3 once the stock tune is selected? I believe it’s turn on first time to get the tuner recognized, then off, then turn on again to have the stock tune uploaded, then off once the completion tone is heard. Can anybody verify this?

Was able to restore my 2003 Mustang to stock today, phew. Thanks to 08’MustangDude for the pdf link with the menu layout. Got no help elsewhere from anyone. Now to get it retuned with my SCT X4 this Wednesday now that I have the SCT 90mm MAF.
