I just completed this guide, and it is 100% perfection. The photos are useful and clear, and explanations are on point. Many thanks.

Hey, wanted to say thanks for this video. Super helpful. I crashed the eff out of my Mavic Mini and was getting an error 30045, "Gyroscope initialization failed. Restart aircraft." Looks like my ribbon cable that connects the gyroscope chip module to the main board somehow got ripped (or possibly melted through, I was flying in a rather warm climate.) Of course, it's the longest and most complex cable in the drone, so it'll be a job to get it replaced. I'm ordering a new one and going to see if I can switch it out successfully. Thank you!!
