This script creates/provides patched firmware binaries for the Cowon D2 (or D2+) digital audio player.
Replacing the firmware of your player with one of these files allows you to use Rockbox on your D2/D2+.
Much more information can be found on the iAudiophile fan forum, here.

-> Read Before Installing

To install Rockbox on your D2/D2+:
  1. On your D2/D2+, go to Settings -> Information and take note of the "Version".
    This is your "firmware version". For more information please click here.
  2. Click here, find your firmware version and click the image.
    Unless you use a theme created by Cassini, ignore the "Cassini" type downloads.
  3. Rename the file you downloaded to the Filename listed in the table.
    Ensure you can see file extensions so you do not add an extra '.bin' to the filename.
  4. Copy the renamed file to your D2/D2+
    It should be alongside the MUSIC/VIDEO/SYSTEM folders etc.
  5. Download the latest Rockbox build and unzip it to your SD card
    Unsure how to unzip? Click here. No SD card? Click here.
