Unlike Magic Leap 1, OS images are not tied to specific devices. Once you've download an OS image, you can flash it using ADB, use Magic Leap Hub's OS installer to install your OS in a few, short clicks, or update directly over-the-air using the on-device OS Updater.

If you're running Magic Leap OS version prior to 1.4.0, you'll need to have Magic Leap Hub installed to update your device. More information about Magic Leap Hub can be found here.

Via OS Installer

Via Device Bridge

Downloading an OS Image

From the home screen of Magic Leap Hub, open the Package Manager by clicking the "Package Manager" icon in the upper-righthand corner of the application.

Navigate to the "All" tab to see all available software and tools. You should see a heading saying "Device OS Versions". If you do not, click on the "Package Manager" dropdown in the upper-lefthand corner, and click "Refresh Available Packages". If this does not work, try reinstalling the app to make sure you have the latest version.

Click on the arrow to the "ML2 OS" section and, from the "Available Version(s)" dropdown, select the OS version you'd like to download. You should see the following:

Confirm that the OS version you want to download is selected and click "Apply Changes". You will be taken to a screen showing the download progress. Once done, returning to the "All" or "My Tools" tabs and selecting the "ML2 OS" section and clicking "Open Folder" will open the folder containing the files required for flashing.

What to do when OS Installer Fails

If the OS installer in ML Hub fails and your device is stuck in a loop of rebooting, you will need to manually flash your device. You will need to make sure you have downloaded the OS image you need to update your device to.

Flashing your device

First, shut the device off and restart it in fastboot mode. Enter fastboot mode by holding the volume down button while you turn the device on. If successful you should see the Fastboot LED indicator on your Compute Pack.

• In Magic Leap Hub, select the OS version you wish to flash from the ML OS dropdown in the "My Tools" section in "Package Manager". Click the "Open Folder" button. Open your computer's command line interface tool.
  • If you are on MacOS, run the following:

    • ./darwin_flash.sh

  • If you are on Linux, run the following:

    • ./flashall_amd.sh

  • If you are on Windows, run the following:

    • flashall_amd.bat

• This will take around 6-10 minutes to flash everything based on the USB speed.
• At the end of flashing, the script will reboot the device, it should be recognized when you run:

  • adb devices

Downgrading your device

Downgrading your device requires a factory reset. Downgrading can be done using the Magic Leap Hub OS Installer, and when selecting an older OS version the Hub will remind you that a factory reset is required prior to beginning the process. 

If you run into issues using Magic Leap Hub's OS Installer, and your device is stuck in fastboot mode, you can use the flashing instructions to complete the downgrade process.
