A few weeks back, I updated the fw on a Tello drone of mine, the update seemed to have finished and then my phone had lost connection to the drone despite being right by it. Any following attempt to power on the drone boots into loader mode, Im assuming the fw itself is corrupted in some way. I can’t retry the update because loader mode doesn’t broadcast battery to the phone, just a bear minimum to update. But since the battery is read as zero, I cannot update it because the battery is less than 50%.
Tello fw update failed and only boots into loader mode.
