I just performed firmware update again, which went smoothly, then I performed the factory reset again which was not great. The screen was black/blank when I held 1,2,3 & 4 MUTE buttons down and turned the power back on. I held them for a good couple of minutes and still a blank screen, so I released the MUTE buttons & tied the power off. I repeated this and the screen came alive but stayed on the Rebooting msg for 5mins. I turned it off & repeated the steps, this time it did its thing quickly and showed the "Factory reset please wait" so i released the Mutes. It completed its process this time.
I'll try it out again today or tomorrow I think (not at my gig) in my car port..
I have to say though ST, its not exactly filling me with confidence so far 🤗
Kind regards Nick
