This is pretty bad.
I was enjoying my player with the v. 1.1 firmware that shipped with it (second batch) ... but after reading all the posts about updating firmware, I decided to go ahead with the update process (even though I had a nagging reluctance since things were working okay).
Anyway, I followed the guide on MP4Nation, updating from 1.1 to 1.2 ... things were fine, though menus were in Chinese ... then I moved on to updating from 1.2 to 2.0 .... and it seems that things worked, but in the final steps, the player never rebooted ... I waited for about 10 minutes and then safely disconnected and tried to reconnect to my Win XP machine and *nothing* ... the player was not recognized.
Further, now the player won't even boot. I try to plug it in via USB to my Win XP machine and it's not recognized.
At the moment, I consider it Bricked(tm).
If anybody has any suggestions as to how to salvage my S:Flo, please PM me (or post to this thread on the chance that others might benefit).
Best regards and (painfully) ... falling back to my Sansa Clip (cry) ...
