I had a problem with my Vu Duo.It was "Stucking in Starting and did not flash anyway".
I search in web and find out many users of this box have the same problem.(you can search to find)
It seems that this stucking problem is for hardware or software fail in bootloader of the box.
Many users and me send email to Vu plus company for Solution but after 1 year any Solution.
I recommend to all they want to buy a box do not buy Vu Plus solo duo uno and ultimo because they
have weak support in software and hardware and an accountable company with expencive boxes.
Send your mails to vu plus company for support request of such problems.
