Got it working. Thanks everyone!

I put all the files on the external MMC1 card and it installed fine.

My big mistake was that I downloaded both sets of files (MMC1 and MMC2).

For anyone else who is new to this, here is what I did:

1. Flash the latest update to the N810

2. Download and put these files on a blank external 2 GB SD card. I used my PC card reader to copy the files over.

local-mmc1.deb
kde-3.5.8-mmc1.deb
kdesup-3.5.8.deb
KDE358.tar.bz2

I too had some trouble getting the complete download so be sure to check the size.

3. Install the files in order as posted by Peguinbait.

4. In Extras run KDE.

For me, if it crashed I had to re-flash to try again.

@dubwise, if I move maps to my SD card and install using the MMC2 files what is the advantage?
