Sorry for the bad experience brought to you.
Could you please tell us the amazon order number?
For the first unit, the unit should take about 25 seconds to boot up like our website writing, maybe the unexpected system buy happen.
Actually the problem would be solved by original firmware installing.
For the second unit, it does not support the DAB box which only work with the first unit.
Could you please check if the screen still flicker and change colour when you listen radio or music?
Please don't worry, we will try to provide you positive solution.
