I made a biggg mistake.

step 1: enter recovery mode: move “hold” to orange position, press rec+menu until it says “welcome to recovery mode”.

step 2: connect your sansa to the computer with the usb cable. a new drive should appear on “my computer”. do not make any changes to this drive if it is not stated dricetly.

step3: download the correct files from here for v1 player

or here for v2 player

or here for rhapsody

and unzip.

step 4: open notepad. without writing anything, save file as sansa.fmt. note: make sure you save as “all files” sansa.fmt so it won’t be sansa.fmt.txt

step 5: copy 3 files (and only them) to the 16 mb drive: sansa.fmt, pp5022.mi4, and BL_SD_boardSupportSD.rom

now you can disconnect, and the sansa will format itself and install new firmware.

hope this helps.
