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.
