2020.12.5 Highlights

Sentry Mode & Dashcam Dashboard Viewer

and also the Sentry mode and dashcam viewer directly on the car screen. We no longer have to tediously move our USB drive to our computer to view the footage anymore!

“Select a clip or event to play the corresponding video. To select video from a particular camera, tap the associated thumbnail marked Front, Rear, Left, or Right. Play pause or scroll by using the video controls at the bottom of the player. To delete a video, tap the trash icon in the bottom right corner of the video player.”

How to Update to Tesla 2020.12.5

When your tesla is ready for an software update, you will first notice a message on your tesla app. If you see an “Software Update” message like below, then you are ready to get started.

You must go to your car to get started. And in order for the software to download, you must connect to a WiFi connection. The software update data is too large to download over tesla’s LTE connection.

You can either click on the yellow down arrow button at the top of your screen, or simply go to “software” on the menu.

Then you should see “Update Available” and a prompt to connect to WiFi. If you are at home, you can just connect to your home WiFi to get started. You can also connect via hotspot to your phone’s WiFi connection if you have enough data to use, but be careful since this is a rather large file, so it will likely eat up a large portion of your phone data if you do not have unlimited data plan. Another option would be to find a public WiFi, such as parking lot of a Starbucks or McDonald’s and try to connect to their WiFIi.

Once you connect to WiFi, you will be ready to start, simply hit the “Software Update” button.

The system will then start to download the file. It took me about 30 to 40 minutes to download while connected to my phone’s 4G hotspot connection. So it is definitely a rather large file. You can still operate your car normally while you download.

Can you can monitor the download progress on your tesla app or in the car dashboard.

When the download is complete, this is when the fun begins, you would be about 25 minutes from all the new features. You should receive a notification on your phone that your update is ready to install, and it tells you how long the installation will take. It was a roughly 25 minutes for the 2020.12.5 update.

Keep in mind that you will not be able to operate your car while the software update is in progress, so you need to find a safe place to park the car for about 25 minutes if you choose to install immediately. Or you can schedule a time for the installation.

Once you hit “install now”, you will have two minutes to do whatever you need in the car before the installation begins and the car stops operating. There’s a two minute warning countdown.

You will receive another notification on your app once the installation is complete.

And there you go, tesla firmware update 2020.12.5 is complete!

This firmware is officially version number V10.2 (2020.12.5 e2179e0650f0).

You will be prompted with a “What’s New In This Update” note on your dashboard. Besides the notes shown above, here are some additional updates in this software update.

How do you guys like the 2020.12.5 update so far? Do you think tesla will eventually allow Sentry Mode and dashboard viewer directly onto your phone app? Imagine getting a notification immediately on your phone if there is a Sentry mode incident and you can view the footage right on your phone in realtime!
