"no sim inserted" error after CM 10.2 experimental

hi :)

as the title says, i was tryng to update to the latest release of the experimental 10.2 (i had already the first one)

at the reboot...the boot screen sayng "galaxy note" was normal ...but the screen stayed black (but with illumination on O_o)

so i recovered this soft-brick with odin and stock JB rom ...

and now the phone doesn't recognize any sim that i put on


any suggestion?
