I had bought 2 extra LV08's that I kept running on luckyminer OS for over a week before converting them to modified bitaxeos today.
First one was down less then 40 minutes before hashing again.
The second one was a little bit different.
At some point when I was soldering I grabbed the heatsink and "something" moved a bit.
I inspected and everything seemed normal.
I flashed modified bitaxeos and it started hashing, but only at 2/3 of capacitly.
From the log files:

Oops, no I had the same as person above.
I took the unit apart again an concentrated on the part that had moved
It turns out there are 2 heatsinks on the LV08:
A large one for the 9 asics and a smaller one for the 3 VRs (voltage regulators)

The only thing I did was push some of the pink heatsink stuffback to the area where it touched the VR (all 3 spots)
Screwed the heatsink back on the PCB and reassembled the unit.

Firing on all cylinders (I should say VR's) again:
