I am having the same thing happen. It is very frustrating. A couple of times it rolled through the banks as if it was possessed. But now it either says Update flash" or it is stuck on Son of Plexi (but you can't do any mods with the preset- frozen). I've done the left nav button and powered on, the Flash Update thru Monkey, firmware update too multiple times. I erased my settings too, and reinstalled those saved presets, but nope. A few times it worked briefly within a bank, A to D, but when i tried to switch banks it refroze back. Help... gig on Friday...
