When updating ios 7
When i Tunes launches you will need to click on your i OS device from i Tunes side navigation.Step 3) – After clicking on your i OS device you will simply need to SHIFT click the Check for Updates button (WINDOWS) or ALT click the Check for Updates button (MAC OS X).Step 1) – Launch the Settings app on your i Phone, i Pod Touch or i Pad, go into the General tab and then the Software Update tab.Step 2) – You should now see a screen stating that the i OS 7 firmware is available to install on your device. Step 3) – Accept the Terms and Conditions and then the i OS 7 firmware will begin downloading.
If things went well, your i Phone/i Pad should boot up succesfully.
Apparently, the cause of the problem is not very clear.
May be this has something to do with the restart loops that the i Device falls into.
You should also be prompt to plug your device into your computer to ensure there is enough battery to complete the download and finish the installation process.
Step 4) – While the i OS 7 firmware is downloading you can exit out of the Settings app and continue to use your device.
Of course if you would prefer this method of updating, you can indeed do it this way.
