Hello, I ve got a problem with my VTBox250,couple of days ago just died(black screen,no charging,wasn t working with E scribe. Today just turn on by itself...the problem is that is not charging,if i left it unplugged ffrom usb just show a Warranty service message,if i plug it with usb without any tank it shows me normal things but without charging,if i plug it with tank shiw the message shorted... I ve checked everything on escribe,i ve do the usb recovery 10 times,i ve updated the software and i ve try hard/soft reboot but seems just dead... then i v e notice that the battery is dead...do you think that i should replace just the lipo or doing something different? Cheers guys
