After a long wait the step by step illustrated guide of how to unlock the sandisk sport is now up. Instead of posting it here I just posted it to the blogpost. Do hope this helps someone and remember to download your music with the icare method first, don’t feel like decrypting the firmware to enable saving music when an option is already available. sandisksportfirmware.wordpress.com
And make sure you try https://sourceforge.net/projects/album-art/ which is free after you dump your music back on the player, nothing nicer than album covers for all the music to appear.
