yes i do
just got my new 254, udpadted the firmware to r11, it boots up in red infomir screen, and I get a screen saying "Output mode mismatch.please change device video output mode to sd or use HDMI output"
I tried using an HDMI but nothing changes.
Nome of the buttons on the remote work, I can not get to the settings to change the output, just have a black screen.
Any idea on how to get to the settings? Thanks.
