For unknown reason, mine now boots up to the InfoTMic screen, then the Sylvania screen for a while, then it goes blank. Nothing no matter how long I wait. I tired 3 finger reset, and get the message "No recovery image is found, try recover from SD" OK so I downloaded system.bin, and put it on a blank FAT32 formatted SDcard. But then how do I tell it to boot from that SD card? If I try the 3 finger reset the same thing happens.. No recovery image.... Is there a different sequence for recovering from the SD card? This is a EX7 unit.
