Hello! I need your advice: I accidentally upgraded my NS2300N directly to 01.05.0000.12 and now it can't be accessed by Smart Navi, only by browser interface. I must find a way to downgrade to  V1.05.0000.09. Please help!!! It's a year since I've been searching forums and all sort of solutions. Also I would like to know the Safe Mode procedure.

Thank you in advance!

Kind regards,
