yhap2003, Either you are trying to update with the wrong firmware or you are using firmware dumps which are not full firmware files.
Try this one it is a full firmware that I have used to recover in the past:

If it installs it wil not fully recover your player but you should be able to then apply one of the ones you have been trying.
