Hi everyone, I am using ESP-Miner-LVXX from https://github.com/mrbonkerz/ESP-Miner-LVXX

I tried to re-flash my luckyminer Lv08 with the firmware of v2.7.1-1.0.7, but v2.7.1-1.0.7 doesn't work.
After several attempts, I found that only v2.6.0-1.0.3 could work properly, and version v2.6.1-1.0.5 including the new version could not work properly at all.

What doesn't work ? were you still able to access the webgui? did the display still work ?
It has happened before that the config.cvs file for the LV08 was included in the LV08 factory image.
That would prevent the ASICS from getting power. In the log files you would find that condition.
If that is the case, once you have a working 2.6.0-1.0.3, just updating the www.bin & esp-miner.bin from the above github via the WIFI WEB GUI interface, would get you upgraded to 2.7.1-1.0.7

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.

Using 2.6.0-1.0.3 does not work completely, and the LOG will show the following error message.

Which firmware file did you use for the initial flashing from the factory luckyminer os to LVXX os?

esp-miner-factory-lv08-v2.7.1-1.0.7
