I recommend that you continue using a 4-pin PWM fan since this way you will not lose the function of controlling the fan, unlike a 3-pin fan that would be working at its maximum capacity and could not be controlled.

If you've bricked your LV06, your only two options are: use the Miner Fixes Debug Guide (hard) or use the Un-Painted web flasher (easy). All you have to do is connect your LV06 to your PC via a USB to TTL port and flash it directly from your browser with a few clicks.

You can find some videos about this on YouTube, or you can view the guide on Un-Painted's GitHub.

Use the BitAxe www.bin version 2.0.7, it is exactly the same as the Lucky Miner 2.3.0

The only thing that changed is the name in the upper right corner, I tell you this because I already tried to request the Lucky Miner www.bin and the only thing they told me is that the factory did not release it

can you upload the www.bin?

I think it's more of a hardware and temperature problem than a firmware problem. I had the same problem as you, the miner didn't work for more than 2 hours so I made a mod to cool the back of the miner because only the back reached 50°C (122°F) without counting the temperature of the main chip. I checked it with my infrared thermometer and when it was completely closed some component overheated and to avoid problems it restarted for protection.

That answer may vary from chip to chip, some chips may be better than others (that's part of the silicon lottery) but you can try different configurations until you reach a stable configuration, in my case the most stable configuration I have is 575/1200, any lower in frequency it doesn't reach the hash rate it should work at.

At the moment the possible causes that I have ruled out are:

-firmware in the latest available version.

-unstable connection: miner is within good Wi-Fi range.

-frequency (525Mhz) and voltage (1200mV): suitable frequency and voltage.

-Overheating: the appropriate temperature does not exceed 55 degrees.

-mining pool: I have tried a large number of pools and the problem persists.

-Try faster DNS.

At the moment I don't know what else to try to stop these types of random reboots.

One of the suggestions I saw was to open ports on the router, but I'm not sure if this does anything.

Or did I just receive a damaged unit?

technically it is possible since it is with the SHA-256 algorithm and lv6 works with that algorithm

It would be great if in future firmware updates in the Overview section of the IP website you could view the Wi-Fi connection like on cell phones to see how good the signal the miner receives.
