Hi all, fisrt I must say that this forum is veeeerrrrry usefull. But I just can't get my (not mine actually, just trying to fix it for my lil' bro) MP3/MP4 player to start working again. The last thing I saw with the firmware upgrade tool was: LISONG MP3 player, version 9.0.50. No brand but within I can see 2 samsung chips (SAMSUNG 643 K9G8G08U0M) and another ATJ2091N chip. What can you tell me about this player and how to get it back on track? Right now I only see a blue screen.
All help appreciated. btw it is detected by the hardware manager as ADFU device but windows explorer can't see it.
