Hi friends,

I have a 4 gb mp4 player which has CTW500 chip( v 9.0.48 ).I had some problems.I couldn't plug.When i tried, player was resetting pc.So i plugged it another pc and i copy my mp3s to pc.And after i decided to upgrade firmware.I think i installed wrong firmware (9.0.50).And now player doesnt open.its just lightning a dark blue screen.When i plugged it pc doesnt recognize it.And of course mp3 utility doesnt recognize it too.Can i recover this player?Good evening.

Open it up, post board ID and display ID so we can find appropriate firmware.

But i couldn't find another id or code on the board.There was just 2 code..

"Samsung 707 K9HBG08UB1M" on the chip on first photo.
"411AI-061011N3-061019-56" below the lcd.

eventual there is "Y2829-V6" is writed outside of the player

Thanks for reply.

First i disengaged lcd from the board and i found boards code.

The code is "MP-783W TSLS v 1.1 2006.05.31"

And i dont know that how can i update firmware bacause i tried a few mp3 player utility but none of them recognized it.

so if you find a firmware for me and tell me that how can i fix this problem, i would be happy.

Good days.

According to this

926W and 735W are equivalent to 783W, so here are your firmware:

Once you get it into ADFU mode, you can reflash firmware.

How can i do this?

Because when i looked the device manager, there isn't any unknown device or etc.
