I tried to update the firmware of LV07. I did what it says to do, but it seems to be a situation where there is no screen and only the fan is running. I tried to update the firmware again, starting from scratch, but nothing happened. I want to fix this problem, please help.
I mean after connecting the firmware to tx-rx, gnd-gnd and tx-rx, gnd-io0, something went wrong during flashing, I can't see the screen, I can't see the error message. I want to factory reset my lv07, please help
Please let us know which tool you used for flashing. Which version you flashed and what was logged by the flasher during the flashing process.
You can wire the LV07 (TX, RX and GND) and display the serial log using the terminal or Web Flasher. What appears there?
