Binaural
As mentioned by tadad, best to extract YOUR own firmware from your player, then modify your OWN fimware with the new images then upload it back into your player.
It's safe to use your OWN FIRMWARE as it's what is from your player originally. There are a lot of incompatible firmware out there with the same version number, so rather than the chance and risk having a 'dead player', it's best to use your own firmware and modify that yourself (make sure you make a backup of it as well).
I have 'reskinned' my player many times and uploading the firmware on it many times, not once has it failed or caused any problems - this is because I'm using my own firmware.
Try that and good luck.
Hope to hear some good news from you.
