Hi FC,

Check out these notes;

Upgrades to 4.1-The TFTP server must support file transfers larger than 32 MB. Version 3.0 or later of Tftpd32 is recommended. If your TFTP server software does not support file transfers larger than 32 MB, then the upgrade does not complete (see the Troubleshoot section for symptoms). Note that several popular TFTP server software packages do not support file transfers larger than 32 MB.

Also, have a close look at the supported upgrade paths for WLC listed in this doc;

Wireless LAN Controller (WLC) Software Upgrade to Versions 3.2, 4.0, and 4.1

Hope this helps!
