This is why you should never jailbreak…

Try holding the power button for about 1 to 2 minutes, if that doesn't work, than plug into iTunes and restore. I suggest you watch some youtube videos on how to jailbreak your iPhone. Make sure you are using the right firmware you downloaded onto your computer. There will be a 4 digit number at the end of the file. Make sure its the same as what your iphone version says in settings.
