Caution

We highly recommend you to use the same version as Chrome/Chromium of webOS OSE. Using other versions might cause unexpected errors.

To check the Chromium version of your target device, do one of the following:
- Execute the ares-device -i command. In this case, make sure username of the target device is set as root. Otherwise the Chromium version won’t be displayed. For more details on how to set up the username, see DEVICE_INFO of ares-setup-device.
- Execute the Web Browser app and go to http://useragentstring.com.
- Visit the webOS OSE GitHub and find a Chromium repository of the latest version. Then see src/chrome/VERSION file.
To download old builds of Chrome/Chromium, visit the Chromium Project website.
