I updated my brand new mac mini (Mid 2011) yesterday, and I have now the exact same issue. I had 6 updates pending, amongst which the EFI update. And after update my mac mini now have the same two failure modes that you see:
1)Powering it on, steady led, and fan speed increasing up to full speed after ~25sec.
2)Pressing the power button while plugging in the power (PMU reset) and press power again to turn on the device, the led does not turn on and the fan starts at full speed.
My is a brand new Mac Mini 2.5GHz i5 with AMD HD 6630M, and 8G mem upgrade. So It should not be related to your RAID configuration.
I have not found any way to recover from this failure

I have the same problem with the Mac mini in mid-2011, the newestmodel. After the EFI firmware update 1.3, the Mac will not start well,and fan speed up to full speed Increasing but the mac does nothing.
I called Apple and they don`t give me another solution to get him tofix. From what I've seen the most likely have to change the logicboard.
My is a brand new Mac Mini 2,3 GHz i5 with 2 GH mem
If anyone has another solution please comment on it.
My mac mini only has 20 days
Sorry for my poor English

Is this update forced? Or can you opt out of it?
Currently Being ModeratedSep 26, 2011 6:16 AM (in response to PAULSG63)
the update is not obligatory, it appears in Software Update.
I do not recommend that you upgrade

I had no problems with the update, but I ran it alone, not with other updates. I don't understand why anyone would run an EFI update at the same time as other updates, or for that matter why Software Update even allows such a thing.

I guess if I download it from the above listed location.. http://support.apple.com/kb/DL1449
then run it by itself.. that should work.

Updated my Mini a few days ago and it doesn't start any more with wireless keyboard, if I plug in Apple USB one before powering on - boots OK, pull the USB right after and continue using a wireless one.
I think it is update issue, not the logic board!?

I talked to apple care today, and they directed me to the apple store for testing and possible service. At the apple store they tested the Mac Mini, also using a wired Apple USB keyboard, but without any luck. My Mac Mini is bricked, and they where not able to get it to start. So they took it in for service to get the main board replaced.

BAAB, Did you let the update happen with the other updates? Or did you run it seperate?
Trying to determine if its the method of upgrade...

I let it happen together with 5 other updates..:/ So might be related to that. Don´t remember what all the updates where about, but one was OSX update, one Final Cut Pro X extras and one Motion 5 Extras. Dunno the other ones.

So... I get home and check my mac mini 2011 and it was already upgraded! I guess it did it with the other upgrades.. Mine was fine.
My mini has 8 Gigs of mem.. Also, I added a 60Gb ssd for my OS and have the User directory on the 500 Gb second drive.

Short update, I got it back yesterday. The Service center said they had to replace the logic board.
It does not make me happy to think that there is no way to recover the EFI, ...
For all the others, good luck that your Macs get fixed soon as well!
