HI Guys thank you for the suggestion. I opened a ticket........ let's wait for LINE6 will answer max for a couple of days, in the meantime I'm going to take the original package to be ready to send it back to the seller.
Thanks.
I'm having a similar issue. Just purchased brand new and updated to the new (1_1 & 1_5) firmware as strongly suggested by Line 6.
The first try upgrade did not succeed because the unit was not even recharged by the base. The second try worked but now the G10T works only for less than 2 hours than it flash red and it turns off. I left it on the base even a full night but the result has been the same: 2 hours and then low battery again. I never had an issue with LINE 6 products so I hope a new FW fix will coming soon. I have 7 days to decide if keep it or send it back to the seller asking the right of withdrawal according to the law.
