Using the extracted dtb file from andriod, i was unable to boot the tvbox (a green screen appears and remains there). Even i converted the .dtb file into .dts and than back to .dtb (because someone is saying that .dtb file is kernel dependent). Still same green screen. I know @balbes150 stop supporting this tvbox due to lack of support from amlogic. But still it the cheapest tvbox and if we defined a methodology of correctly extracting the .dtb file and do some changes than it can be documented and used for others (If only the .dtb file that does matter here). Or if we know the methodology of adding support of any tvbox (if the .dtb file is the only we need to change) than i can put an effort to document it all.
