I found that there was a EC update for my blade, so I tried to install.
At first, it seems to work properly. Update has done in 5 seconds, and I rebooted my blade.
But after I entered Bios, EC version was still 2.0, not 4.0.
I executed single click updater again, I could install update again, and same thing happened.
Updater told me that my blade's EC version is still 2.0. I've tried to update using updater over 20times, but EC version is still 2.0
Can anyone help me? Sorry for my bad English
