Re: DEAD PLAYER RECOVERY GUIDE
 

Ow, really thanks man!! My SigmaTel / Durabrand Mp4 started to crash in the middle of the musics, then i tried to upload a different firmware..... this is what "killed" my Mp4.....

Thanks to the guide i was able to put it in the "Recovery State" and to upload the original firmware. Now its working really fine, because with this it stoped to crash in the middle of the musics.

Really thanks again.

Obs: I will try to upload the version of my firmware to the forum.
