Need Info about my Firmware and MP4
 

I just recently buy a china PMP Player with 1.3Mega Camera - PSP style and after a few it got broken. I can't open it anymore that is why I decided to bring it to technician and the tech told me that the problem is "NO POWER". The tech warned me that he will erased everything to fix it. After 5 days i got my MP4 back and it's fixed but I noticed that there are some changes. It seem that the tech installed different firmware but I don't have any idea what is it. I try to search on the net but I cant find anything because I didn't know anything about MP4.

This is what my MP4 look like....

It said that the version of my firmware is Sunplus V8.1xxxxxxxxxxxxxx
