NAND script and won't load past apple screen

Standard troubleshooting...

1. Remove apps from the Recently Used (multi-tasking) list...

- From any Home Screen, double tap the home button to bring up the Recents List

- Swipe up on the app preview card to remove it from the list

- Press the home button when done.

2. Restart by pressing the sleep/lock button until you see the slider. Slide to power off. Restart by pressing the sleep/lock button until you see the Apple logo.

3. Reset by pressing the home and sleep buttons until you see the Apple logo. Takes about 5-15 secs of button holding and you won't lose any data or settings.

4. Restore with your backup.

5. Restore as new, i.e. without your backup. See how it runs with nothing synced to it. You may need to try DFU mode (Google for it).

6. If still a problem, it's likely a hardware issue.
