Big problem. Impossible to restore after iCloud Find my Mac remote wipe

[marcocc]

I lost my mac, then in icloud.com I asked to lock with PIN and remote wipe the mac.
Then I found it back.
After the system started up it went to a grey screen that asked my my PIN. Entered the PIN but nothing happened because it was in endless waiting loading...
So rebootted and automatically entered in the restore partition.
Via Disk Utility the main hard disk is there but deactivated. The boot utity doesn't see the main hard drive. Now way to format it. It's pratically there but "inactive".
I think this is the way apple put a wiped mac in secutiry, but how to restore it now? How to unlock the main hard drive partition?
I'm stuck

Did you happen to set an EFI firmware PIN before it was lost as an added security measure? If not then what you did should've worked.

There is no EFI password... I can set one, but it doesn't change the situation.

Did you ever back-up your stuff?

not backupped recently...

Well, do you have anything important that you haven't backed-up. At this point, its best to cut your losses and do a fresh start, then load backed up files.
