sph da120 sd internal please

Recommended Posts


To fix the cards you have to put the file TESTMODE_N.KEY and the card locked in the sd slot of the radio in a fat32 pen. You turn on the radio with the pen connected and the card disconnected. when the software error image comes out you connect the card and wait 5 or 10 seconds you disconnect it and reconnect it and wait for a blue screen to appear that says mode change.You can remove the card and connect it to the computer that is already working and you put the image in again.
