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
It must be LV08 version. It is impossible to use LV07.
