Unhappy Issue regarding ARTMOD v5.0 | 4.4.2 | E97520A

Hi,

I update from ARTMOD v4.2 to v5 today. Installation was successful but after booting I kept getting this message: "Unfortunately, the process com.android.systemui has stopped" and can't do anything on the screen.

Now when I try to restore from back up, I can't access recovery mode anymore. (Vol down+power). Is there any other way I could access recovery? I can't also go to download mode.
