I had dead player, then I decided to find firmware...
9.1.52 was on dead player... I was dead but windows reorganized it as flash storage device.
I found DIGIPOD SD-18N (1G , 2G ,4G) , 9.1.51 version, and after upgrading and removing player, thing get just worse. To explain: the player is now “USB 2.0 (HS) ADFU Device” but there is no drive letter (no drive). I can’t see it with MP3 player upgrade tool, or Disk Manager. Here is some pictures of s1clone:
