hello to all... i received the update today and downloaded via wifi. then i installed.. the problem is during the install my droid guy ended up on his back with "error" under him. then once the phone rebooted, i had a padlock show up when the Samsung name appears and under that it said "custom". my wifi wont turn on and there is a lot of lag from when i swipe my screen to turn on my phone. i tried downloading the update via 4g and the same thing happened. any ideas.. i am unrooted
