I am trying to update to 4.3 over my home wi-fi but for some reason it keeps getting to only a certain percentage of the update downloaded (last attempt it was about 62%, this time it's only got to 3%) and then seems to just stop. I'm on my laptop atm which also connects to the internet via our wi-fi and that seems to be behaving itself tonight, so i'm not sure what's going on. Please help!!
EDIT: I now have a new problem. After successfully downloading 4.3 for the second time, i have again got a message appear on my screen telling me that the update data that has been downloaded is corrupted, and asking me if i want to download it again. Now what?
