I had to help 2 persons who flashed your factory 2.61.-1.0.4 image on a virgin LV08 with luckymineros.
Resulted in only 33% of hash power, only 1 of 3 VR's enabled.
In order to confirm, I had one virgin LV08 left that I converted my self and I can confirm

It turns out it has the config.csv from the LV07 is included in the LV08 factory image.
The LV07 has only 1 VR gets initialized and you only get 1/3 of the hash rate.
downgrading to 2.6.0-1.0.3 and upgrading www.bin & esp-miner.bin to 2.6.1-1.0.4 works great


Might want to look into that

Thank you for all your efforts
