[AC Question]

I am using un rooted version of S3 i9300.I successfully updated it to 4.3
after a while again I got an update which was around 10mb.i started updating it using wifi,but while installing it shows errer,so I tried using kies3.i clicked both "i accept" bottons.after 100% of download it gives an errer message again..
can you solve the problem?ASAP
