A couple of years ago I bought the full version of Malaysk's firmware for a PX30/RK3326 Android 9. works great.I have new head units now, the Phoenix SC7862 Android 10 and a Ezonetronics K4811 Android 11I searched the forums for these but it's quite empty. do these translate to something I can search for? like MTCD/MTXX ?Or is there a thread about modded firmware for them somewhere?
