The reboot works if your firmware is also (pre)rooted.
You should also have an xposed able firmware.
What screen resolution do you have? (800x480 or 1024x600)

Now I've noticed that your MCU is of type MTC
C - are you sure you are on the right thread? Because as far as I know, only MTCB & MTCD types are discussed here!

Good news, I asked around, and it seems that you could use
MTCB firmware on your unit. Let me know what screen resolution you've got, to recommend an appropriate pre-rooted/xposed firmware.

Something tells me that your resolution is 800x480, so see post
#484 for firmware, too.
