Hi,

-For using USB as a source, the device has to be formatted as FAT32 to be recognized by the LifeCycle Controller

-If you can update via iDRAC you can use ."exe" format of files. 

 

I'm sharing some different methods you can do easily. 

 

Platform specific bootable this is an ISO for all firmwares

You can use Rufus to make bootable media https://www.dell.com/support/kbdoc/en-us/000141551/how-to-create-a-bootable-usb-device-with-rufus-to-update-dell-servers

 

You can also try to use the virtual media function via iDRAC (if you do not have iDRAC enterprise here trial version https://www.dell.com/support/kbdoc/en-us/000176472/idrac-cmc-openmanage-enterprise-openmanage-integration-with-microsoft-windows-admin-center-openmanage-integration-with-servicenow-and-dpat-trial-licenses#noteAgreeToDownload)

Or other than platform specific ISO you can use server update utility for all drivers and firmwares https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=p003w&oscode=ws8r2&productcode=poweredge-r820

To install SUU you can find differents methods on this website https://www.dell.com/support/kbdoc/en-us/000128194/updating-firmware-and-drivers-on-dell-emc-poweredge-servers

 

I believe those documents will help.

 

Let us know how it goes!
