Hi there.

I did flash try all yes all factory and mereg bin files Lucky Miner LV07 from un-painted-org/ESP-Miner

My Lucky Miner LV07 works OK setup everything works web UI change settings all OK but doesn't mine at all.

Error from log:

there is even a web flasher for the LV07 (and the LV06) to get open source firmware:

I fixed it: LV07 with open source firmware!

They won't release it
