HELP!

My Samsung note 3 Sm-N9006 was already rooted when I bought it, though it doesnt have CWM/TWRP and SuperSu. However, all rooted apps are working. So I really want to change the phone's font so I downloaded Font installer *root*, because no font style is available in the settings. However, after I installed a font from the app, it prompted me to reboot my system, I clicked it and when it boots, its already stuck on the samsung logo.

Whenever I use the button combination vol down + power + home, it just opens normally;
when volume up + Volume down + power / Volume up + power + home / Volume up + power, this is what is shown,,,

Select boot mode:
[VOLUME_UP to select. VOLUME_DOWN is OK.]

[recovery mode]
[fastboot mode]
[normal mode] <<==

I can use the volume up to choose, but whenever I click volume down, nothing happens.
