Objective

• Apply a firmware update to your Halo Collar using the wired update method. This is only necessary if your collar can't update by being connected to Wi-Fi while charging. 

Background

The primary way to update your Halo Collar's firmware should be wirelessly. To do this, plug your collar into the charger overnight, and make sure it's connected to WiFi. When these conditions are met, the collar should automatically download and apply any firmware updates. 

If you are still having trouble downloading firmware update, please follow the steps below to manually complete a wired update.

Procedure

You will need:

1. Your Halo Collar
2. The charging cable that came with your Halo Collar, or another USB-C cable.
3. A computer (PC or Mac) -  with the ability to plug your Halo Collar in via the USB-C cable (some computers require an adapter)

Steps to complete

Important: There are three firmware download files below; one file for Halo 1 and Halo 2 collars, one file for Halo 2+ collars, and a third file for Halo 3 collars. Make sure you only download the firmware file intended for your collar type.

1. Check your collar to confirm if it is a Halo 1, Halo 2, Halo 2+, or Halo 3
   • In the Halo App, tap Settings then My Collars and identify the collar that needs a wired update
   • Between the collar name and the serial number, it should say Halo 1, Halo 2, or Halo 2+; Make sure you download the corresponding file below
2. Download the correct Tar File below into an easily-accessible location, like your Desktop or Downloads folder. Use the download button of your browser to download the Tar File.
   • If your collar is a Halo 1 or Halo 2, download this firmware update file
   • If your collar is a Halo 2+, download this firmware update file
   • If your collar is a Halo 3, download this firmware update file
3. Connect the collar to your computer with the USB-C cable
4. Open your “File Explorer" (Windows) or “Finder App” (Mac) on your computer. Note that there should be a variety of folders on the leftmost side.
5. Make sure your collar is resting, with the USB port facing up (as in, the collar is upside-down)
6. Long-press the power button on your Halo Collar (about 5 seconds), until your collar vibrates twice, and the Halo Logo light flashes RED a few times. Your Halo Collar is now in “low-power mode”, meaning that the core functionality is paused and the collar is ready to accept a firmware update.
7. You should now see the collar appear as a “drive” in your File Explorer or Finder App (likely D: or E: on a PC or “noname” on a Mac) as a USB drive.  Double-click on the drive to open it. Inside, you will see folders named “log” and “config”.  You may also see a folder named “fw”, but do not worry if it does--or does not--appear.  It should look similar to the below (with or without "fw" already there):
   1. 
8. Next, navigate to the location where you saved your Tar file, which will be named named "halo-fw-package_1.6.30.v1.tar" or “halo-fw-package_1.6.30.v2.tar” depending on which file you downloaded. It most likely downloaded straight to your “Downloads” folder.
9. Select "copy" to copy the file from your computer and then navigate back to the Halo Collar’s “drive” (note to remember: you’ve already learned that this could be called “D:”, “E:”, or “noname”).
10.  Paste the firmware package folder that you copied into the Halo Collar’s drive. Do not open any pre-existing “fw” folders.  Just open the “drive”, and right-click to select “paste”. This should be done at the “Root” level (top-level). 
11. You should now see the tar file, along with  “log” and “config” on the collar's drive. 

It should now look similar to this:

Once you have copied the file to the drive, turn the collar on with a short press of the power button (about 1 second). The upgrade will begin within about 5 seconds, as indicated by the battery light blinking Red. The upgrade will take 3-4 minutes to complete. 

Once the upgrade is complete, the battery light will either change to solid Green (meaning the battery is fully charged or blinking Green (meaning your battery is still charging).

Now, you need to start the collar one more time to finish the upgrade. Unplug the cable and turn the collar on with a short-press of the power button (1 second).

Your update is now complete!  You will now have the updated firmware that will continually allow for "over-the-air" updating while your collar charges at night and is connected to the Internet. You will need to allow your collar to calibrate its GPS outside in an area with a clear view of the sky for around 30 minutes before using it on your dog again after a firmware update.

Thanks for your patience!
