Thank you for the additional feedback, much appriciated.
I have tried to upgrade to 2.7.1-1.0.7 using webgui, but after refreshing
www.bin or esp-miner.bin, the webgui and display do not work, but the fan will run at full speed and the restart button does not work.
Did you power cycle after the upgrade ?
off (unplug power) - wait 3 seconds, turn it on again ?
Using 2.6.0-1.0.3 does not work completely, and the LOG will show the following error message.

really looks like the setup for an LV07 instead of the LV08
