I tried installing Rockbox using the required Sansa firmware (bin file). I tried files clipplus01.02.15.bin, clipplus01.02.13.bin, and clipplus01.02.16.bin and get an error each time.
My Sansa clip is version V02.01.35s if that helps.
If you can, please direct me to where I can download the appropriate bin file.
Thanks so much.
