Hi All. I just joined and I'm hoping I can get a little help.
Last year I bought 2 units of a 3rd gen Nano clone. They were supposed to be 4 GB each but as it turns out one of them is actually 2GB.
Well the 2 GB worked (and still does) but has two lines going across the LCD vertically.
The other unit will not play any songs. There is a message which says format error! but they are in MP3 format.

I thought that maybe I should do a firmware upgrade, but this finding the correct firmware seems to be pretty difficult. I even have a CD that came with the units and has a firmware file on it, but when I try using that it tells me that the Firmware's protocol is different from the one on the firmware.
This is what I see when I go to the firmware version:BO-25002
AK1025_LKD_V32
2007-11-10
9.1.52
2005-01-09

Anyone know what to do with this unit? Any suggestions or FW files for this unit you can recommend?

Thanks in advance
