At least two people have been understandably confused by error message `Error: Firmware programming failed: Unable to establish connection after flashing. Possibly bad image.` when using opentitantool to flash HyperDebug firmware for the first time. The cause being that with the jumper wire left in place, the board will not boot into the firmware just flashed, but instead boot into the DFU bootloaded again. Adding an explicit step in the instructions calling for removing the jumper wire _before_ running opentitantool should hopefully avoid this.
