Okay, the instructions say the following:
# Unzip this file to receive pp5022.mi4
# Rename the resulting file to OF.mi4
# Right-click to download the following file and place it inside the "sansa" folder: pp5022.mi4
So the result of these steps is that you have TWO files in the Sansa directory on your computer, one named OF.mi4 and one named pp5022.mi4. Is that correct?
# Boot up your device and connect the USB cable (make sure you have set the USB Mode to MSC/Rhapsody)
# Copy pp5022.mi4 to the root of your device
The root of the device is just the top directory on the device, right?
# Copy OF.mi4 to the "system" folder within your device (make sure you have set Windows to "Show hidden files")
I have Windows set to show hidden files, but I don't have a System folder on my device (e250r). Might it be called something else?
Thanks for your help!
