How to fix a black screen when my samsung note 3 turns on?

[AC Question]

I have got a samsung galaxy note 3 (sm-n900) recently. When i wanted to software update the samsung by using the settings it said "Your device has been modified" or something like that and i did try to remove the custom status on the phone but i couldn't. That lead me to kies 3 which was the samsung application which i used to update the samsung galaxy note 3. I did what it said"Do not remove the plug/usb wire off the samsung note 3. The update was successful but when i turn it on it only shows the boot logo (Samsung Galaxy Note 3 SM-N900). After that it would show only a black screen. I already did what i can: Wipe data/factory reset, wipe cache partition. PS: The android system recovery works because it showed me a android with a gears really qucikly and then showed me a android on the floor with a red exclamtion mark sign. Then it would show this: h t t p : / / i m g u r . c o m/BDkmq1M
Please help me.
Thank you for helping.
