[jaymz1]

Hi dudes... whats up?..
well my mp3 of 2gb Trevis says starting and stays there...
I did that pc recognice the Adfu stuff... so i need the firmware. i opened the player and i have this things:

i think this are from the battery
Model n° 042020S
Execute Standard Gb/T18287.2000

then in one tiny piece atacched to the player shows:
TEAS767
VDJKAD
05
DPG6503Y

then in other piece shows:
ATJ2091N
61078 DB C10

and behind the screen says:
NNNIX KOR (the first two "N"s were backwards like the R of Korn... like on a mirror)
HY27UV 08A05M
TPCB 706A
MBSJEN61K


You can see how i dont understand what number should i use or not... anyway... in the cd have a .fw named "$ACTSDK$.fw but i tried to recover it and says it cant be done... wrong thing and stuff.

well guys u are my only hope... the player dont have even a month.. but the seller dont want to repaired it...

Thx in advance for your help...
