Here is a document that will explain what version you can upgrade to from an existing version.  This should get you to 6.x

Have you gone through the release notes of the firmware you wanted to go to?  Kindly read the section posted below.  It will give you a brief description on the firmwares you need to install FIRST prior to full upgrade.

Try downloading the firmware again, maybe it's corrupt.

I use 3CDeamon and never had any issues.  You are also upgrading to 4.2.176.0 first correct?  Like leolaohoo mentioned, try to download the image again.

Try to tftp the image you currently have on your WLC and see if that fial or not.  Have you tried another PC/laptop with tftp?
