I posted a picture at the top of this thread which chip I used. It was the flash memory chip, the oblong one.
You can often get a player into update mode without opening up the player,
doing this:=

1) Switch the player OFF using the main on/off switch.

2) Hold down the "MENU" or the "PLAY" button and keep it held down.(try the other buttons if these dont work)

3) Connect the usb to the player.

4) Wait for about 10 seconds before releasing the button.

5) You are now in "ROCK USB" upgrade mode!

6) Then just start ConsumerUpdate and upload a working firmware and try it.
