16GB Player needs help!

[thewonder]

Hi,

I have a 16GB no brand name and model. The back cover is silver. This player can play movies, music, and radio but, the vocal of the music sound very light. Below is the firmware info prior to format this device:

xid_1025_k9GAG
2009-02-28
9.1.54
2005-01-09

Below are the info that I found inside this unit:
Board ID: BKS25056MV6A
No:071116
on back of Display: N02070297AA0905084
on the side of Display: BL 0297H1 KM090226
[FM RADIO IC]: Component CL 6018
[RAM][ROM][CPU]: AK1025
[H]Nand Flash Memory: Samsung 907 K9LBGO8UOM-PCBO

It took along time to format the unit using Windows then failed. Eventually, I can not found this unit any more, power on with hour glass on the display. I have tried three AK1025 firmwares from s1wf.com but no luck. Please advice!

Thank you!
