Hi Guys/Gals,
I had the same Issue updated my Iphone 4s to Ios 7.0.2 and my iPhone got stuck in recovery mode
Here is the steps to fix it
1. Put your phone in DFU mode
Step One
Open iTunes and connect the iPhone to your Mac.
Step Two
Press and hold the Home button and the Sleep/Wake button at the same time.
Step Three
After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode.
The iPhone screen will remain black
2. while you plugged your iPhone and opening the itunes go to windows/system32/drivers/etc and open "hosts" file as administrator with notepad
3. remove the last to lines with word apple in it
4. this is the most important action don't close the hosts file
5. while the hosts file still open go to itunes press shift + click restore choose the custom ipsw
6. Navigate C:\Users\<user name>\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates
7. Select the correct ipsw file for Iphone 4s select iPhone4,1_7.0.2_11A501_Restore.ipsw
8. Restore Iphone from iTunes(Factory Defaults)
And then you can restore you backups from iTune or cloud etc.
