Rollback in Lifecycle Controller

You can update any component, for example BIOS, in both Lifecycle Controller and the operating system environment. After the update is successful in the operating system environment using DUPs, you can enter Lifecycle Controller and revert the component to the version that was previously installed before the update occurred.

Lifecycle Controller supports platform firmware rollback to the previous version. If the operating system has a non–functioning application because of a BIOS or firmware flash, reboot to Lifecycle Controller and roll back to the previous version.

  • NOTE: The BIOS and firmware can be only rolled back. The Lifecycle Controller application, the Dell Diagnostics application, and drivers required for operating system installation cannot be rolled back to an earlier version.

If you have updated the BIOS or firmware of the system only once, the rollback feature offers the option of reverting to the factory-installed BIOS or firmware images. If you have updated the BIOS or firmware to multiple versions, the factory-installed images are overwritten and you cannot revert to them.

  • NOTE: Rollback is not supported in the operating system environment. To enable rollback, ensure that you boot into Lifecycle Controller.
