i tried to update my appradio4 sph-da120 to firmware 1.11 and it failed then went to software error screen. I needed a backup image for sph-da120 but couldnt find one..  I tried flashing the avicimg6100.img file to a new card and now get updating 0% version 0.00 -> 0.00.  then says update failed. please press "home" to continue.  well i have no home button because its a full touch screen. Any help is much appreciated!  what can i do now?  anyone have a sph-da120 sd image?
