ok with SBUU/SUU combo. I've used: cdu_2.1_core_339.iso OM_710_SUU_FULL_ISO_A00.iso with success..
If you try to use the F10 Platform Updates option in System Services to update firmware, but get the following error:  "The updates you are trying to apply are not Dell-authorized updates"   FIX:  Make sure your server is running a minimum firmware revision for the following two items:   ***The current Lifecycle Controller Repair package will NOT resolve the  issue, as it only updates the LFC to version 1.5.1, which is too old.   The iDRAC is easily updated by using the “Update” option in the iDRAC webpage interface.   The Lifecycle Controller can (as of 11/9/12) only be updated in a Windows or Linux environment.  For  ESXi users, you can boot to OMSA Live and apply the LFC .bin update via command line.  Or create a Linux bootable Repository Manager utility.  You CANNOT simply create a custom repository and point the System Services to it.  That won’t work. Or you can boot to the SBUU/SUU combo, but I have not yet verified if that works.  [IMAGE]
