I was downloading v10 using my phone's hotspot as my wifi can't reach the driveway. The progress bar reached 100% then stalled. I tried contacting Tesla but no has gotten back to me yet. I have a service appointment coming up in two weeks, so I'm looking for an ideas or experiences on how to fix this. I'm also curious to see how many people download updates via hotspots. Supposedly, Tesla doesn't recommend hotspot downloading.
