After we used the E09 reimaging flash drive, our E09 Classmate was successfully activated (at a mentor's home, because we do not have internet access at our workshop). A week later, after using files copied from a local rookie team, we reimaged our E11 Classmate. Using the same internet connection as before, Windows fails to activate, showing an error different from the one in this thread. It's the error reported by SMHS in post #6 of the
referenced thread.
I reimaged the Classmate several times. I was never able to get the "Use the automated phone system" option to appear, using any of the available login accounts. I'll be working on it again this weekend.
