Friends.
I encountered same problem with note ii n7100.
First of all downgrade from 4.1.2 to 4.1.1
after downgrade phone will stuck at samsung logo.
Dont panic.keep pressing vol.up+home button+power key release after few seconds.now select wipe/factory data reset.phone will reboot .now baseband must be ok.
Write imei now and phone will display imei and android version 4.1.1. Network will be fine now.
4.1.2 version will not allow to write imei.
