R720 Failed iDRAC

Hi There,

Recently tried to update the idrac and lifecycle controller of my R720 using the iDRAC-with-Lifecycle-Controller_Firmware_JWKMP_WN64_2.50.50.50_A00.EXE update through the idrac webinterface - it seems like the update failed and bricked the idrac - as now I'm unable to get any response from it and the fans are always spinning at full speed. I tried disconnecting power and draining flea power - the dedicated NIC of the IDRAC is also non functional.

Is there any way to reflash the idrac and return it back to functionality or perhaps a repair service ?

Thanks

James
