IPhone 4 running iOS 6.1 stuck at apple logo?

My iPhone 4 is running iOS 6.1 with the evasi0n jailbreak. I have recently uninstalled SiriDr off my iPhone, and I rebooted it. Now it's stuck at the apple logo. I have already tried to restore it in iTunes, but it won't let me. It's giving an 3194 error. I don't know what to do now, can you please help me?

Have you tried activating the auxiliary interphase transition module? If that doesn't do it for you, try adjusting the photonic muon balancing or fork the polarized subspace carrier.

Okay what you need to do is put it in DFU mode.hold the home and power button at the same tim then when the apple logo goes away, hold the power button for about thirty more seconds. Then plug it into your computer and then restore it

Just watch this easy tutorial to get it unstuck:

Hope this helps you out!

I had this issue just recently and I traced it back to a corruption problem in the firmware. If you downloaded the ipsw from a site, there's a chance it didn't download properly. What I had to do to get it working was find the 6.1 ipsw from a torrent site, (I used the bay) and it downloaded without corruption. Torrents are a great way to assure file integrity as it downloads sections of files from different peers and must have a reliable way to reassemble everything once the download is complete.

Once you get it restored again, use evasi0n to jailbreak. Follow this video for a step by step process.
