For the 2nd time in a year I cannot boot my M20D. When I fire it up, first the Line6 logo appears for a moment and then the screen with the spinning boot-up icon appears. I left it on for about 30 minutes and it never resolved booting, it just remains on the boot screen with the spinning logo. I shut it off, waited about 10 seconds, then tried again. Same deal. I tried 4 times, over about 2 hours, to get the M20D to boot. I tried with and without the SD card plugged in. I am not using wireless and am powering the unit through a nice power conditioner. I am on firmware 1.20. I have about 8 mics plugged into the unit, where they have been plugged in for about 4 months without ever having been removed. It has booted up just fine in this configuration twice a week for the last 4 months.
Has anyone else had their M20D get stuck while booting up? Any known remedies for this issue?
