Which Firmware did you try to install? According to your problem description you are most likely trying to downgrade, which is not possible under certain circumstances.

For example - Build data: 04.03.2014, N9005XXUENC2 KSA (Saudi Arabia) KitKat 4.4.2. The device doesn't understand anything. Is it possible to fix the problem ????
Thank you for answer

Apparently you can only downgrade AP but not the modem. First flash your new ROM, then flash your current modem version afterwards.
