OLED unit will not display anything other than M5Stack Logo

 Hi everyone, I'm using the OLED unit with the online UI flow and I can see that OLED is supported but no matter what I do, the unit will only display the M5Stack's Logo and M5STACK text, nothing else. 
 I've tried writing texts, drawing pixels or rectangles, turning the unit on/off before displaying anything but to no avail.Any help is appreciated.

 Have you burned the firmware to the device? Maybe reburn the firmware again?

 Yes I have and I've tried it on few other devices, the same result.

 Same porblem here. I've burned the newest firmware and use 1.8.3. Only function woks, is on/off, invert. I cannot change what to display.
