I took the plunge and did the update myself. My motivation was having the nearest Chevy dealer with Bolt certification be 175 miles away. I carefully read all of the directions as shown by Electrek at the beginning of this thread and took some notes. I followed them exactly. I had the instructions open in my iPad while I downloaded on my laptop to an old 512 kB flash drive cleared of all else. It was heartening to see every screen show up exactly as pictured with no deviation. In the Bolt, the same. It took 13 minutes and counted down the seconds with no “freezing”. It restarted twice as described and now I can see the new screens and the new version when I query for it. I accepted the risk, which is not “zero”. I will post immediately if I detect any evidence of malware. Bolts are coming to the tri-state very slowly but I sure hope the “circle of Chevy embarrassment” gets smaller within the next year.
