however a freid of mine gave me a mp4 player looks the same as this one http://www.mympxplayer.org/image-asp148.html and was working fine 1 day then not worked since as its now dead i followed the dead recovery guide on here and got it to light up to a blue screen as in the guide with firmware (B806K8V1[1].1_2006-09-25_9.0.48 ) as im not sure if this is the correct firmware for this player could someone please help and let me know it this is correct or am i doing somethink wrong many thanks.

forgot to add that it was a 8 gig hacked type if that helps.

larger 1 is ( samsung 719)
smaller 1 is ( ak1025 )

many thanks
jason

little update people but now im stuck on this one i have flashed this player with this (B806G6V1.7_2006-10-16_9.0.48.fw) i downloaded from this site and now it's sort of showing signs of life i have tryed other firmwares from here but these only give a dark blue screen how ever with the fimware mentioned the mp3/4 player looks like its trying to work but theres about 1/4 of the screen still white at the top and the colours are not right and the welcome screen that loads is spelled backwards.
