After selecting deep colour the screen has turned immediately to black so I can not access anything still stayed black after turning off and on again. 9s has latest firmware etc. So attempted re flashing unit but screen stays black and No screen or info when attempting to re flash but shows up on the units display. My TV is 1080p max resolution.
Unplugged the HDMI Port and take the AV Connector to the TV. Boot the Box and change the setting. Power Off, and go to HDMI Port. Start the Box.
This is a bypass, but the problem still needs to be solved. The FW should ask for a confirmation and if not received within 10 seconds the setting should be reverted.
Yes it is a bug in the Zidoo firmware, but my information is also only to help the user, so he can use the box again.
