Hi @ all
I have a MP4
1 G.B
9.1.52
It doesn`t have any problem but i wanted to ask for the following :
1 - What is firmware upgrade useful for ?
2- Do i have to upgrade my current version ?
3- If yes : From where can i download it ?
4- Can i change themes of this player ?
5- What is the online mode ?
That`s enough for now
Thanks in advance for help
