Did you implemented the update for the ME CSME 11.8 CON H DA v11.8.93.4323
The CSM tool will inquiry the board ME fw revision.
All tools and MEGA links for the Intel Management 2-15 thread are working correctly.
EDIT: This has nothing to do with UBU, the guide is here: Intel (Converged Security) Management Engine: Drivers, Firmware and Tools (2-15)
