NOTE:

1. Be sure you install updated firmware. You cannot downgrade your phone’s firmware in BB5 phones which includes all new Nokia phones including N-Series.
2. jaf allows downgrading but your phone doesn’t allow it as your phone has some special security built into it. So no use of trying it. You’ll get an error message.
3. You can reinstall your current firmware also if you have its package. It is supported. It can also sometimes solve little issues.

lets start

1. Conect your phone with PC Suite Mode
2. now open OGM_JAF_PKEY_Emulator_v3.exe

3. click GO
