I left my VRCPG-BSG sitting arund for a couple months and when I went to use it I pressed a button yto wke it up and the screen was blinking / flashing - alternating shades of blue. No button was able to stop it from doing this. Pressing and holding the dot center button showed th ebootloader screen but then when t immediately back to blinking screen again.
Taking the batteries out and leaving them out for a while (couple of minutes) allowed the VRCPG to start up normall into the "start installation checklist" screen. However, running a node rediscovery starts up the flashing screen again.
