160gb downgrade version? I'm at 2.0.4

I am having some issues since upgrading and I don't know if it's hardware or software related. all the music was showing as gone (but the memory was still allocated). So, I restored it and was going well and loading the music. Woke up this morning and it's show no music, no artists, etc...I've done a factory restore but it's still showing 2.0.4

It's a Late 2009 160gb Generation 7 I think mc297LL



The only firmware versions I'm finding are



1.1.2

2.0.1



Both are giving me an incompatible error. Any suggestions?



Any idea what version it came with?
