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 ?

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

Of course, it is completely in line with teaching practices
But it just can't work normally
It must be LV08 version. It is impossible to use LV07.
