Note: Firmware updates are separate from Toast app updates. 

Note: Elo V2 and Elo V3 devices share the same physical hardware. You may see them referenced together as Elo V2/V3. The difference lies in their operating systems and firmware versions:

• Elo V2 devices run Android 7.1 and use firmware versions in the 3.XX.XXX range.
• Elo V3 devices run Android 8.1 and use firmware versions in the 4.XX.XXX range.

Note: The Elo V2/V3 firmware upgrade process happens through ToastMobile. There are tiers of upgrades for these devices:

• Devices on firmware below 3.46.302 must first update to 3.46.302 before upgrading to 4.XX.XXX.
• Devices on firmware 3.26.77 or lower will be prompted to install the Elo support application before installing the firmware update. 
  
  

Steps to Update Firmware

     Note: Don't unplug any cables or the monitor while the update is in progress. 

1. Navigate back to the Toast passcode screen and enter your passcode to view your pending update. 
   1. Note: If the update does not display upon returning to the passcode screen, this may mean that the update was previously displayed and dismissed. In this case, the update will reappear again in 8 hours or you may use the following steps to trigger the update immediately:
      
      1. Delete the Toast app (for instructions on how to uninstall an app, see Navigate Your Android Device).
      2. Reinstall the Toast app (see Install the Toast App for instructions).
      3. Log in using your Toast email address and password.
      4. Wait 10 minutes and enter your passcode. When the update prompt appears, select Update now.
2. You’ll know the update is finished when you arrive back at the Android home screen. To confirm the update was successful, repeat steps 1–4 to ensure the current version reads 4.50.540120051+a or higher.
3. If the firmware update continues to fail or you’re unable to update, RMA the device or recommend an upgrade to Toast Flex if the device is out of warranty.

     Note: Depending on the current firmware version on the device, more than one firmware update may be required. 

1. Open the Toast app and tap the three dots in the top-right corner.
2. Tap Device.
3. Review the Firmware Version to see your current version.
   1. If your firmware version is 3.46.302 or higher, only one update is required to reach the latest firmware.
   2. If your firmware version is between 3.26.77 and lower than 3.46.302, you’ll need to complete two updates to reach the latest firmware. After the first update completes, repeat steps 1–4 again to install the next update.
   3. If your firmware version is 3.26.77 or lower, you’ll need to complete three updates to reach the latest firmware. The first step will prompt you to install the Elo Support Application before proceeding. 
      1. If this occurs, select Install Support Application.
         
      2. When prompted, select Next and then Install. The firmware update will continue once this application is downloaded and installed. The update process takes a few minutes, during which time you may see Elo progress screens.

Devices on a version of ToastMobile 2.94 or higher:

With the release of ToastMobile 2.94, Elo V2/V3 devices now include a new way to manually start the firmware update process directly from the ToastMobile main menu. This improves troubleshooting, especially when the update prompt does not automatically appear after pin coding in. After pin coding in, follow these steps:

1. Scroll to the Setup section, and click Elo Firmware Update
2. The device will display a message such as “Update available, check back soon.” This means the device has begun downloading the update in the background.
3. After you believe the update has downloaded (anywhere between 1–30 minutes depending on network conditions), tap the Elo Firmware Update button again.
4. If the download is complete, the device will proceed with the same firmware installation steps described above.

The safety and security of your Toast hardware and restaurant is a top priority to us, and thus, we periodically roll out changes to further enhance said security and safety of your hardware and network. 

A portion of these changes may require you to update your devices to the latest firmware version available. Use the information in this article to update your Elo V2/V3 accordingly.
