Failed Jailbreak

[SuperDaff]

To keep this short, i tried to jailbreak my iPod touch 4th gen 16bg using redsn0w, when i selcted the wrong .IPSW file for doing so, a wall of text appeared, which ended in "Panic: we are hanging here". Now it stays with a black screen, and nothing i try to do will either turn it on nor restore it in any way. I've currently tried almost everything. Please, help me!
