I have a s1mp3 standard type MP3 player, capacity: 2GB. When I try to use the voice record function on the device it restarts. I believe re-installing the firmware would solve the problem, but I have been unable to find the correct firmware. I have tried searching s1mp3.org, driverguide.com, google and this forum looking for information but I have been unsuccessful. Any info would be greatly appreciated.

The board number is:
2006.06.10
QTT-2051-B

It says that its current version of firmware is:
MP3 Player
AT51075A
2006/03/03
3.5.35.0000
