The Zune is actually quite serviceable in 2023. I saw a video of someone modifying one to take a Micro SD Card, a Bluetooth Chip and a bigger battery! I don’t think there are any modifications to the Operating System you can do, but the Bluetooth off and on is actually piggybacking off the Wifi Switch for power to the BT board.
Or the Microsoft ipod… RIP Zune
