Help me. Can't update my galaxy I own a Samsung SCH-i545 Galaxy S4 and can not update to Jellybean 4.3. The wi-fi it says: Software update is temporarly unavailable.vTry again later. Kies does not let me update either. I really want the 4.3 update so I would appreciate some help..
Try waiting. It's usually because loads of people are upgrading. There's a limit; you should be able to in the next 2 days.
