Thank you to everyone that helped. I un-bricked my e260, and i was able to get rockbox as well as the new bootloader on it, so i can now read and put music directly onto my e260.
Unfortunately, a new problem has arisen for me. although my mp3 player now says that it is connected, my computer recognizes it as an unknown device, so i cannot sync. microsoft says that i need a new driver for it, but the driver updates do nothing. does anyone know what happened or how i can get the computer to read it?
