Jelly Bean Update Via Kies

view story

http://androidforums.com – Hello Just wondered if anyone could help. I have unrooted Galaxy S3 and have just gone to complete latest update via Kies. All was going smoothly, download to phone was complete, when error came up on PC USB device not recognised. :( Have updated the drivers via Kies but left with phone saying "Downloading Do not turn off target." Worried now about rebooting phone. Also cannot get Kies to now connect with phone. Can anyone help please? (General)
