@shuff12​

Unfortunately it doesn't work, does anyone have any other ideas to apply?

one detail more... in the support page the last iDrac update for dell poweredge R640 is the 7version, but in the server bios say 4version

Hello,

At first please check the .exe format (x86 or x64) is correct. If possible you take a downtime then you can do a cold boot. Because previously ran an upgrade firmware installer places a RAM drive onto OS. It may related with power cycles. If the BIOS update fails on the first attempt, it could be due to the Intel Management Engine (ME) not entering recovery mode. This is known to happen if the server has been powered on for more than 24 days since the last AC power cycle. To resolve this, perform a complete AC power cycle before attempting the BIOS update again. This involves gracefully shutting down the OS, removing all power cables, waiting a few seconds, and then reconnecting the power cables. After the power cycle, attempt the BIOS update again using the iDRAC web interface or the Lifecycle Controller.

You can use firmimg.d9 file after extracting the .exe file. ".d9 — Contains both iDRAC and Lifecycle Controller firmware" to updating iDRAC FW you can use either Update Package for MS Windows 64-Bit or firmimg image format file.  Sometimes .exe files do not run properly on the iDRAC GUI. In such cases, as a workaround option is to download the file iDRAC and extract it. Once you extract you will get firmimg.d9 file and that file can be used in iDRAC GUI for update.

Other than you can use LCC to update.  PowerEdge Server: LifeCycle Controller Update | Dell US

Hope that helps!

@rmalasquez​ Did you get this resolved? I am following. Thanks

Hi,

Did you try my post in the topic? If it didn't work, can you give some more details? What server are you using and what is your current version and which version are you trying to upgrade to? (Major jumps between versions are not recommended)
