Sony NW-A1000/1200/3000 Port Index


This series of DAPs shares the same microprocessor as the iAudio X5/M5 series players. The firmware appears to be encrypted as there are no visible strings after the initial "NWA3000" and IDA-Pro doesn't seem to know what to do with it.

Port Status

There is no code written for this device. Things that need to be done are: find a way to recover from a bad flash and understanding the firmware files. Perhaps someone with a A1000/1200 could try booting with the drive removed to see what happens (the A3000 requires de-soldering 4 pins just to get at the HDD). I found a report that said holding the volume-up button while connecting to a PC would execute a recovery mode but haven't been able to confirm this.

Firmware Update

Sony NW-A1000 Firmware v2.01
Sony NW-A1000 Firmware v3.00
Sony NW-A1200 Firmware v2.01
Sony NW-A1200 Firmware v3.00
Sony NW-A3000 Firmware v2.01
Sony NW-A3000 Firmware v3.00

Firmware updates are performed by placing a NW_AX000.bin file in the root directory and restarting the player. For the v3 update, an extra file called NW_A3000.UPG is placed in the root as well. You can extract the files from the installer executables with common archive programs (7zip, WinRAR, etc).

Test Mode

There is a production test mode built into the firmware (bootloader?) whose usefulness at this point is unclear. It can be accessed through the following method:

  1. Turn the power on.
  2. Long-press the Hold button to set the hold on.
  3. While holding the Link button, press the buttons in the following order: Up → Down → Option → Up → Down → Right → Left → Right → Left → Left → Play/Pause → Option
  4. Long-press the Hold button to set the hold off to enter test mode.

To exit, hold the Back button for until the unit shuts off.
