After upgrading to this version now my tv shows "HDMI mode not supported" on screen
It shows it turning on the box and before android loading screen
I'm able to control the device through the mybox android app, the device still works well with the new firmware
reflashed, factory reset, rebooted several time but still the same message
now I'm downloading the september release to downgrade the firmware and to see what happens
Any other suggestion?
thanks
my tv is:

*update:
1) after downgrading without factory reset still the same error on tv (but reseted firmware before downgrading)
2) done another factory reset and now the box works again as before. now i'm running with rel 3.0.1.1
Someone has a clue?
