What method did a user use to install a custom ROM on a company-owned Android tablet?

The method used to install a custom ROM on a company-owned Android tablet is referred to as rooting. Rooting involves gaining administrative access to the Android operating system, allowing the user to modify system files and settings that are normally restricted. By rooting the device, it becomes possible to install a custom ROM, which is an alternative version of the Android operating system that can include different features, interfaces, or performance enhancements not available in the stock version.

This process is particularly relevant in the context of customization and performance improvements on Android devices but also carries certain security risks and potential issues with device stability. Rooting can void warranties and may lead to security vulnerabilities if not done properly. Overall, rooting is integral to enabling users to take full control over their devices, which includes installing custom ROMs.
