Sadly, my G10T seems to have died after a week of use... :( The LED keeps flickering red, the LCD on the Spider V doesn't show charging status or transmitting status... I've gone so far as to do a factory reset on my amp, just in case (I hope the Remote App stored the few settings i've made... if not, no biggy...)
I've opened a support ticket, but maybe somebody has an idea what I might try while waiting for Line 6's answer?
