Sabre58 with bad head

[pclab]

Hi

I have a case with a Sabre58, that can't be recognized correctly.
After changing headmap I could get it ID right one time. I have access to SA with head 0 and I have made a full backup of FW.
The problem is that after I tried to clone it, it failled it can't get it to ID well again.
It detects as UNICORN, 5GB of size.

Since I have the full FW, isn't it possible to load modules to RAM, so I can access the data?
I have tried to load Dir Mod to RAM but gave me an error.
This is not the way?

Thanks
