M8024-k boot stuck after upgrade IOM Coprocessor Firmware

Hi 
Firstly, I have to apologize for my poor english.

Recently, I have been working on M1000E with a pair of M8024-k which is one of them not work properly.

The guy before me told me that he was upgrade IOM Coprocessor Firmware (version 11 > 12) on one of M8024-k, The upgrading went success but M8024-k no longer boot at all.

^^^^^^^^^^^^  It stuck here, won't go anywhere.

What I have try.

1. try to boot with difference verion of image (oldest that I can find like 4.x.x.x to lastest 5.1.17.1)
2. move M8024-k to other slot.
3. try to boot M8024-k without any module on it.

No matter what I try it still stuck at
SOC unit 0 attached to PCI device BCM56820_B0

Is there any way to fix this problem or it just broken switch. Thank you.
