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
