Hello JohnnyBitGoode

I know the procedure for flashing an ESP32 MCU. This is how I got my firmware onto the LV07 using the bitaxetool.
Yes, exactly: my own firmware! I have explained everything in the German thread.

In a nutshell:
- The LV07 with its 2x BM1366 is practically identical to the Bitaxe Ultra-Hex, only with 2 instead of 6 ASIC chips.
- I adapted the firmware from TinyChipHub and made it work for the LV07. So far my LV07 works perfectly.

You can find my firmware at:
Repository: https://github.com/un-painted/ESP-Miner-TCH/tree/unpainted_2.3.3_lv07
Binaries: https://github.com/un-painted/ESP-Miner-TCH/releases see under “Assets”

Warning: I take no responsibility for my firmware. So far everything works fine. But I am not a hardware specialist. And if you break something when flashing the ESP32, it's not my fault.

Enjoy!


Thank you for your offer! Unfortunately, I was unable to restore my backup of the 1.1.0 firmware. And since I only have one LV07, I couldn't make a second dump of the firmware.

But: I no longer need the LuckyMiner firmware as I'm using my own firmware. I leave it to others who want to go back to the LuckyMiner version to contact you.

Hello unpainted.

Are you familiar with using a jTAG device with a 6 pin probe attached?
If so, I can send you a copy of my LV07 v1.0.0 backup factory firmware and you can flash your LV07 back to life with the jTAG and probe.
If you take off one of the metal panels on the LV07, it's the one on the left if you're looking directly at the LCD screen, you'll see the jTAG probe points.
I bought both the jTAG and 6 pin probe from AliExpress.

I did the same thing as you and tested several other firmwares on the LV07. But because I learned how to flash my Bitaxe MAX (which has no USB port) and LV06 using the jTAG, I was able to revive them! Luckily I had 2 other LV07 miners and I saved a copy from one of them and flashed it back to the non working one without any problems. The only mistake I made, was not making a backup of my LV07 first before I flashed it as it was my newest LV07 with the newer 1.1.0 firmware!
