After you reset your device you will need to upgrade it with a full firmware these are very hard to find. I have found another version of 3.2.13 that appears to be a copy from a CD so this may be a full version. There are 2 one for a player with FM Radio and on without.
If you are going to open your player and reset your chip I suggest you download these firmware as you will need them after you reset your player.
