The firmware is in build.prop. ro.forfan.adaptans.enable=1
ro.forfan.adaptany.twidth=1280
ro.forfan.adaptans.height=720. Ossuret has ro.forfan.adaptany.enable=1 in build.prop
ro.forfan.adaptany.twidth=1280
ro.forfan.adaptans.height=720
forfan.extscreen.twidth=1280
forfan.extscreen.height=720. Ossureta went outside. it will dump you Junsun firmware. I struggled for 30 minutes to do this. it is best to disconnect the cube from the radio with the ignition off, wait 5 minutes, connect the cube, press reset, turn on the ignition and touch the display with five fingers. The flash drive must still be connected before performing the procedure.
