1. if it dies, then you need the full firmware. you should have a look at the Downloads section and match the details in 'Firmware Version' in settings of your player and get the corresponding firmware.
2. upload your theme at
http://uploaded.to and post the link here.

i will see if i can theme it for you. but i can only theme it if it is version 3.5.35 or 3.5.37
3. lol even i dont know why the hold pictures are there in the firmware because there isnt an actual hold function in the player
