firmware
 

Probably everybody will laugh.
But, I don't know anything 'bouth mp4/5 player.
I just know that yesterday I bought a cheap one 8G 3'' MP5 player and I've read about these firmware.
I have 2 questions:
- is these firmware are upgrading something on the MP5 player, or just restoring some damages ?
- Today I have noticed that on radio, after 2 minutes or so, the device is automaticly closing. A firmware updating can solve this?

Thanks
