[Q] Archos 70it2 topic

This is a gen8 tablet, correct? I've been looking around everywhere on how to install SDE but can't find anything. I've tried downloading the gen8 package from the Archos website, but when trying to install the .aos I get "Error 207, not compatible". Information seems to be hard to find. Any help?

Model: 70it2
Firmware: 3.2.81 (Android 3.2.1)
Build Number: HTK75D
