Can you try to update BIOS using iDRAC. You can upload Windows DUP package to iDRAC to update it. You can refer below link for details. [URL] 
Howdy, I'm trying to get an R430 updated with Bios, Firmware, etc.  I ran the SUU and that updated most things except the BIOS update failed.  I then tried downloading the manual BIOS install file and that also failed.  I did a Racreset, as that was recommended by someone, but it didn't help.  Have also tried rebooting which also didn't help. I didn't try updating from the Lifecycle Controller but I guess I'll try that now if I can remember how that works. It's trying to update from 2.9.1 to 2.15.0 Just wondering what else I can try to get this working. [IMAGE] Thanks!
