It's a 2.8" 4GB touch/camera/FM/MP3 player, in an iPhone knock-off housing (even the model/brand info printed on the back is a match for the iPhone... But this is one of the cheap China knock-offs) I dont know what chip/firmware, as I can no longer see the display to check there, and I have not taken it apart...
The splash screen displays nice and brightly and says Welcome, for about 4 seconds, then it goes black/blank.
If I wait a few more seconds, and touch where the "Music" icon belongs, it will play music. I remember the music screen well enough, I can fumble around enough to skip songs, change volume, start/stop, etc.
So, the player is not dead.
My daughter (it's her player...) was experimenting with the settings, and turned the brightness all the way down.
I've tried the reset button, and that just seems to reboot the OS without re-storing factory settings/memory.
I'm hoping that the display will come back if I can increase the brightness setting, or restore the factory originall settings/memory.
