Re: My Galaxy S3 won't turn on after recent update?
Oops looks like there is some problem with the update it may have broken your device down !! :O I would say try opening it again... and if this still doesn't work then I am afraid but you may need to try factory resetting your device, or if that doesn't help you may have to reload the firmware again over your device. Firstly I would recommend try performing as factory reset (One more thing factory resetting will remove all your personal data including images,videos, etc) . And if that still doesn't helps then head over to the sammobile/firmware section download the stock ROM, get the latest version of ODIN downloaded and flash that Stock ROM over to your device with the help of ODIN. ( I would not recommend performing this if your device is till covered under the warranty as this is going to void your warranty ).
