The wilson.ltd.xfou is NOT, I repeat: NOT the official producers page!
It is a fanpage of some french person, but sadly, he doesn't make it clear it's a fansite.
We have seen this mistake quite often at our own forums.
Our forums are solely dedicated to the wilson s1mp3 player, and we have built up quite a bit of expertise on recovering dead players.
The project is located at:
www.s1mp3.orgWe're actually dedicated to making an opensource replacement firmware (which is veeeery slow work), but in the meanwhile, we're being generally nice people, and help others with their broken players.
I think it's safe to say we're te most knowledgable source on the web (save maybe the producer, but they're chinese) about the wilson s1mp3 player.
(among others: we have a collection of about a 100 different firmwares, which may or may not work for your player, but you can always try)
Hope it will be of use to you!
Regards, Crunchy
s1mp3.org crew
