Hi everyone ! I need help with my Note 4~

I accidentally pressed UPSM and now i totally cant use my phone. Blank Home Screen, no icon at all. Inside setting menu it only shows Wifi, Bluetooth, Airplane Mode, Mobile Network, Location and Sound.

Other then this there is nth that i can do at all, no network, cant receive any msg or watsoever... i cant go into recovery mode either as it stuck on the android logo like forever!

It might be because of im using Nova Launcher and froze the original launcher that cause this.

I really really need help as i have only 1 phone. Hope all Note sifu out there can giv me some suggestion on what i can do to be able to use my phone again. I tried googled for over an hour but still cant get any answers for this problem
