SMC bootloader flash fails

We have an Intel Xeon Phi 3120A for which we can't update the SMC Flash and SMC Bootloader flash. Any suggestions are greatly appreciated !

First of all I'd like to mention that the blue LED is not blinking at any time during the procedures described below. It is always solid blue. Not sure if it's supposed to be like that.

When we first installed the board in the computer it had flash version 3.72 so we ran a flash update on it to bring it up to the current version (3.90).

We ran:

micflash -update -v -device all -log micflash.log

and the log file shows the following:

Fri Oct 24 16:48:27 2014: micflash: Tool version: 3.4-1

Fri Oct 24 16:48:30 2014: mic0: Transitioning to ready state...
Fri Oct 24 16:48:39 2014: mic0: Exit status: 10

Then, we followed instructions provided in other posts and we power cycled the computer and then, immediately after reboot, without starting the mpss service, we ran the following command:

micflash -update -v -smcbootloader -device all

but unfortunately we get the same message:

Fri Oct 24 16:53:55 2014: micflash: Tool version: 3.4-1
