Unbrick the Eachine Lizard 95 – How To Reach The Boot Pin

June 29th, 2017

Today I bricked this little drone by flashing the wrong firmware (whoops)!

Turns out that the correct board to choose when flashing a new firmware is “OMNIBUS“. Oh well, good opportunity to learn how to take this thing apart.

  1. Unplug the camera plug from the side by gently pulling the cable out. Optionally also remove the props (I didn’t) to have more maneuvering space later on.

2. Set the drone on its back, and remove the 8 screws circled below (4 for the top frame, 4 for the boards stack).

3.  At this point you should be able to remove the top frame (the one holding the camera and antenna), as well as being able to gently lift the board stack. BE CAREFUL not to pull the motor wires, which are soldered to the board. Remove the ESC board’s feet (circled in red) by turning them counter clock-wise.

4) The ESC board can now be separated from the flight controller board. The boot pin is the one highlighted in red. Short it using a pair of tweezers or some other conductive material, then plug your drone to the computer via USB. If the buzzer emits a steady beep (instead of an intermittent beep), you’re good to go. You can now flash a new firmware using the Betaflight app.

Safe flying!

    Hello Pierot, I am afraid I am in the same situation, bit I am not sure. How did you knew your lizard was bricked? I tried to flas the wrong firmware as well but not sure it worked, as soon as I tried to flash the firmware nothing happened on the computer and the lizard starts beeping non stop. If I go in betaflight and check the version it says 3.1 when I try to flash the correct firmware the lizard starts beeping again. So I don’t know what to do? Any ideas or suggestions?

      I was lucky and couldn’t flash the latest software because of a driver issue on my computer. Got it fixed now 🙂
