I have a T5 I was needing to update. It has sat for a long time because I only used it in my 5th wheel. So I was updating it and the power went out only half way through one of the updates. Now I cant get it to load anything old and I cant load channels or change settings or anything. It has become a total brick. I have tried everything I can think of to fix it. Can someone please help with step by step instructions to restore to factory and then get to the latest update for it. I still get the guitar screen to come up and can get to the settings but haven't been able to make any changes that work.
Thanks
