Full Disassembly Guide for W580i

[Velocity21]

I just got a full new housing for my W580i since my current one has 6 broken number keys and scratches all over. I've been searching around for a guide to disassemble the whole thing but all I can seem to find is how to take off the front faceplate. I'm doing a whole color switch so I need to replace everything. Does anybody know where I can get instructions on how to do this? Thanks
