When ever I'm trying to update my phone it gives error update is downloaded but can't open (8018830f)

Have you checked how much memory you have available? The download / unpack operations require A LOT of spare memory.

Have you soft reset your device? Power and Vol down until phone vibrates. The only other option that I had with my sons phone was to keep trying at various times of the day.

Best of luck
