Iphone stuck on apple logo after jailbreak?

I just jailbroke my iphone 4s with the new evasi0n software(ios 7 jailbreak).it went through the process fine and its now stuck on the apple logo. It also will not connect to itunes. Should i contact apple or do you have any suggestions. I tryed restarting the phone multiple time ans still no luck. P.s i have IOS 7.0.4

I had the same problem. Download your 7.0.4 IPSW, Put your phone into DFU mode, connect it to your computer, open itunes (if not already), itunes should say your phone is in recovery mode and give you the option to restore. What you want to do is SHIFT+click the restore button. This will bring up a window that will ask you to select the IPSW you want to manually restore with. Once this is done run Evad3rs app again and it should work. I know it's kind of a pain because you loose all of your apps, but after doing this you'll get your jailbreak and you can just reinstall them anyway. Whatever you do make sure it doesn't try to update to 7.1. Once you're done with all this download a program called umbrella it will save your phones SHSH blobs which will allow you to restore back down to 7.0.4 in the case you upgrade beyond it by mistake.

^you can download the ISPW from there if you like. I got mine from there as well.

If the process gets stuck somewhere, it's safe to restart the program, reboot the device (if necessary by holding down Power and Home until it shuts down), and rerun the process.
If you get an error on OS X 10.8 saying that evasi0n can't be opened, control-click (or right-click) the app and on the revealed context menu, choose 'Open.' On the ensuing dialogue box, choose 'Open' as well.

I find these from: http://www.syncios.com/blog/evasi0n7-ios-7-untethered-jailbreak-is-available-for-ipod-iphone-ipad/

Hope these help.

Try to turn off your phone for few hours without turning it on, then turn it again, see if it improves. If there's no improvement and you are still stuck with a logo, it can be that the jailbreak process was not successful or the jailbreak software used was not credible.
