1. Back Up the Mesa 3 Tablet
Although the user data is retained in two of the upgrade pathways, Juniper Systems strongly
recommends always backing up all critical data on the Mesa 3 tablet before updating the OS and EC. To
back up your tablet, use one or more of the following methods.
■ Save your apps and settings to the associated Google account. To backup to Google, select Settings
> Google > Backup. Tap Back up now. This method may not back up user data files and side-loaded
apps.
■ Copy your files to a microSD card. Remove the microSD card before upgrading the tablet to prevent
the microSD card from being erased.
■ Connect an external hard drive to the Mesa 3 USB port and copy your files to the hard drive.
2. Update the Android OS
The process for updating the Android OS was developed by Google.
To update the OS,
1. Power on the tablet.
2. Make sure the tablet is connected to the internet.
