I just tried to update my iPhone to 5.0.1 custom firmware. Created the NO_BB file, restored using that through iTunes and it progressed till the end. But after that, when iTunes told me to keep it plugged in and restart, the screen just stayed black. I eventually plugged it out and tried pressing both home and power button, but it doesn't work.

It seems stuck in the DFU mode every time I plug it in now. iTunes asks me to restore every time I plug it in, and I get an error if I try to restore using the custom .ipsw file I made. Is there anything to get my phone turned on from here? Not sure what I did wrong.
