[Q] Note 2 - sim card not recognised after update topic

Hi,
Sorry I'm posting a Note 2 question in the Note 3 thread, but I didn't find any Note 2 threads...

I flashed the latest (official) firmware for the GT-N7100 from sammobile and now the device doesn't recognise the sim card, so the phone has no network provider...

Does anyone have any idea what can I do to resolve it ?
