I bought a new one Line6 G10 two weeks ago (before reading this post).
Couldn't charge it (always blinking red) until I was prompted to update to latest firmware.
Now it could finally change, but from day one the play time is up to 30 mins. And during the charge the green light kept blinking on and off, as if it could never determine it is fully charged or not.
So they are still selling faulty stuff.
Good thing is I returned it to the store I purchased from with full refund. Very disappointed and what a waste of time.
