Custom Sony Walkman firmware by MrWalkman (NW-A40, NW-ZX300, NW-WM1/A)

MrWalkman, a user from Head-fi, has created 3 custom firmwares for the NW-A40, NW-ZX300 and NW-WM1/A. The new firmwares bring improved sound and features. I would highly recommend anyone with these Walkmans to check out the firmware, especially on the NW-A40.

Fortunately there is another method that helps remove the volume cap and restore FM radio function to the NW-A55L for example. In addition, for those wanting to change the language of their Japanese model to English, this guide is for you.
