- Also try DFU mode after try recovery mode
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.

Otherwise post in the correct forum and provide more info like does it happen when you open Safari?
Do other programs work OK?
