Do you have the RCA LYRA PEARL, with the folding out usb plug? RCA has made bunch of different mp3 players and has reused the LYRA and the PEARL name. Mine has both names on it, and the firmware file below is for model numbers TC- or TH-1602 or 1604.
One time I replaced my battery and my unit would not go any further
than the Pearl logo. So, I downloaded the firmware upgrade
, and followed all the troubleshooting instructions that popup when you start the program:
start the program,
remove the battery,
hold the play button while plugging into usb,
release the play button the the term "initalizing" replaces "searching",
check the box that says "format data" (you can try it first without this checked, it may work and will save your music),
click the start button to replace the firmware.
After I did this, my pearl started normally, and my computer recognized it again.
