One of my friends who has upgraded his iPhone 4s to the latest version of iOS, i.e., iOS 7 beta, faced minor problems with the new OS version. The main problem is the inconsistency of the OS.

Though there is no need to set your phone to DFU (Download Firmware Update) mode, if you wish you can set it to DFU mode on iPhone with the following quick steps. Just hold down the home and power button for 10 seconds. Then release the power button while continuing to hold the home button for at least ten to 30 seconds.
After iTunes recognizing your phone hold the Shift key on a PC or ALT/Option button on a Mac. Click the “Restore iPhone” button which will bring the option to choose the iOS6 .ipsw file from a pop up. Brows and select the ipsw file which you have downloaded earlier for your iPhone or iPod touch. Then click “Restore”.
The restore process will begin once iTunes will validate the IPSW firmware file. Wait the process to complete. It takes time. Once the process got completed, your device will be running iOS 6.1.3 or 6.1.4 as you opt.
That is all. Your downgrade from iOS 7 to iOS6 has completed. Any doubt? Just watch the video tutorial below.
