Have you tried loading the previous firmware level that was on the controller? I'd also try to load an emergency bootloader image. If yo've tried those, I'd try to find the earliest firmware that I could for it.
I'm sure you've seen it, but here's a link on WLC upgrades: http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_examp le09186a00805f381f.shtml. There are a few useful things in there. Jason Boyers - CCIE #26024 (Wireless) Technical Instructor - IPexpert, Inc.

This is all I can see: Launching BootLoader... Cisco Bootloader (Version 4.0.191.0) .o88b. d888888b .d8888. .o88b. .d88b. d8P Y8 `88' 88' YP d8P Y8 .8P Y8. 8P 88 `8bo. 8P 88 88 8b 88 `Y8b. 8b 88 88 Y8b d8 .88. db 8D Y8b d8 `8b d8' `Y88P' Y888888P `8888Y' `Y88P' `Y88P' Booting Primary Image... Press <ESC> now for additional boot options... Boot Options Please choose an option from below: 1. Run primary image (Version ) (active) 2. Run backup image (Version ) 3. Manually upgrade primary image 4. Change active boot image 5. Clear Configuration Please enter your choice: If I try to update using option 3, it ask you to update RTOS (no), update code (yes), but in this step I try to download to the WLC de .aes file and fail when all the file is downloaded. I want to remember that I need some files about the code image and download to the WLC when it ask for their. Thanks.
