My iPhone 4 (Version IOS 5.1.1) was updated to version 7.1. After installation, the iphone screen has been showing constant flashing of the apple logo - every 5 seconds or so. How do I fix this?

Hello there, SoftDr1nk.
The following Knowledge Base article provides some great, practical steps for troubleshooting your issue:

- If a single application is not responding or stops responding when it opens, you can force it to close.
- If the device is unresponsive or if certain controls aren't working as expected, restart your device.
- If the device remains unresponsive or does not turn on (or power on), reset your device.
- If there is no video or if the screen remains black, verify that the device has enough charge to turn on:
- If you are using an iPad, ensure that it's connected to the USB Power Adapter supplied with the device.
- Let it charge for at least twenty minutes, then see if it starts normally.
- If there is no image on the screen, press the Sleep/Wake button to attempt to wake the device.
- If the screen displays a red battery icon, continue charging the device until the battery is fully charged. Learn more about charging iPhone and iPod touch, or iPad.
- If the above steps do not resolve the issue, or the if the screen remains black or shows a persistent Apple logo, try restoring with iTunes:
- Connect the device to your computer and open iTunes.
- If the device appears in iTunes, select and click Restore on the Summary pane. Learn more aboutrestoring iOS software.
- If the device doesn't appear in iTunes, try to force the device into recovery mode, and then restore it.
- If the above steps do not resolve the issue, contact Apple.
