I recommend updating your phone using the phone updater. Smaller file and faster.
How?
Backup your phone first by menu-app-file manager-backup-option-backup now(will take 5-10mins)
Then, go back to home screen. Click the dial pad n type *#0000# to see your current firmware then click option check for updates. Follow the instruction there. I have successfully downloaded(15MB) and updated my phone in about 15mins.
