Did this ever get solved? I haven't used my G10 in over a year. Just got it out and got all of the firmware up to date and now the G10t constantly blinks green. Doesn't matter if it's in the receiver, guitar, or out. The only way I got it to stop was to keep it unplugged from the receiver for 4min so it goes into sleep mode. Then once I plug it in to the receiver the cycle starts again. Constant green blink.
