This is the page for the Sony NWZ-S540 series (NWZ-S543, NWZ-S544, NWZ-S545)
I uploaded a copy of the original firmware v1.0.1 here: firmware.sb
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.
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?
