iPhone won't reboot

[iMore Question]

So, I installed evasion for ios7 on my laptop and 'successfully' jailbroke my iPhone 5.
But once it did the last reboot, it stayed at the screen with the apple logo.

I've tried holding down the power button with the home button but it does the same thing.

Please help.

Put the iPhone in DFU Mode and restore. Good Luck.
