joined the forum today because I tried updating to the new .08.
I wish I searched before doing anything but now I tried updating it and then halfway it said "update failed" and now it's not even turning on... I tried restarting the car and it does nothing. I will try to disconnect the battery and see if that does anything later tonight. I searched on the internet only to find that it's risky to install update using the TW supplied memory card which is what I did.
I bought the F770 via Massdrop back in April of 17 so hopefully I have a warranty?? It was hardwired by a professional shop so I'm not sure what they did but it was working fine until the update.
Any advice would be appreciated, thanks.
