The RCA Lyra M4604 is a media player with a 1.8" color LCD screen. It is powered by an internal rechargeable 3.7 volt 350 mAh lithium-ion battery. It has 4GB of Samsung flash storage. The firmware is upgradable.
HardwareA scan of the insides of the player is attached. I have more and better scans coming in the next week.FirmwareThe firmware is upgraded by copying a file named 'firmware.sb' containing the firmware onto the root of the device and restarting the device, and it will begin the upgrade. Running binwalk results in some interesting output. The firmware.sb file is attached as a zip. TODO: Add results of binwalk on firmware.sb Upload better scans.
