After my 6 month old G10 started losing transmission no matter what channel I used, I checked Line6 website and see that there's another fix, I thought cool that must be for my problem. I already had the G10 that comes with the 9v power source, so the overheating didn't apply to me, they said when I called them to check. Moving on I followed the directions and had the updater installed, then the new software. Then I plugged the transmitter in and powered up the receiver and plugged it into my computer via USB, using the cord that came with the unit and it turned off my computer, Twice! Called them and they sent out a new one already with the current download in two days, cool, but when I plugged it in to charge , I came back and the green lights were still flashing, before they went steady indicating fully charged, along with the transmitter light being steady. After 3 hrs and still flashing I unplugged it. I called them and was told that it's caused by the update and use the transmitter light to let you know when it's charged. Also while plugged in the green is flashing 123 and the red is on 1, then three, then two and continues to do this. So anyone else having this problem or any other I didn't list. What sucks is mine was working fine and it just started losing reception periodically, from auto to 1 and so on. Seems from what I've been reading is that there is way to many fixes that seem to be making things worse. Thanks!
