Sony NWZ-S540


This is the page for the Sony NWZ-S540 series (NWZ-S543, NWZ-S544, NWZ-S545)

Port status

There is no Rockbox port for this player yet

I uploaded a copy of the original firmware v1.0.1 here:


The Sony NWZ-S540 features 12 hardware buttons: power/option, play/pause, left, right, up, down, home/back, volume up, volume down, hold, speaker/earphones, reset.

Chip labels: 9VAI8 NWI79 G8KB?

98or 9B 2113A

STMP3780 A3PTX? A00941AU? TAIW



Recovery Mode

One can reach the recovery mode by powering off the unit and plug the USB cable while holding the power button. There are two other alternative methods:
  • power on the player (without USB cable plugged), hold power and plug the USB cable while holding power for at least one or two seconds
  • plug the USB cable, hold power and press the reset button while holding power for at least one or two seconds

Apparently the same firmware is used for several players. The model is determined from two pins and/or the MMC. The following players are handled: E340, E360, E440, E440K?, S540, BB. This is just a wild guess and it does not mean in any way that one can take the OF from one and put it on the other, there might be other differences.
