I am facing problem while downloading iOS7.0.2 software. I am getting error 'Software update failed'. I am using Wi-fi to download this software.. Can anybody help me to download this software?
1. Reboot your computer and your router.
2. Download the latest iTunes version (11.1)
3. Turn off your i-device.
4. Put your i-device in DFU Mode
5. Select to restore and update your device after iTunes detect it being in recovery mode.
Once it is downloaded go to the following location on your computer and put the downloaded file there
Mac
~/Library/iTunes either in iPhone Software Updates or iPad Software Updates
Windows
C:\Users\USERNAME\AppData\Local\Apple\Apple Software Update (Windows Vista/7 probably 8)
Then when you connect to iTunes and click update it will extract from the file instead of trying to download it from the servers.
