hi gvdgvdgvd
Sorry but I cannot help you with this, I can not know if the firmware is OK or not, But it most likely NOT OK.
These are not a good type of player to upgrade the firmware or to do modding.
If you want to mod your player then the best is the NEW Rockchip 27xx series player.
If killing your player would make you sad then please don't try to update this player it is a bad idea.
