Using this old trick should enable you to preload/unlock BF4 earlier.

Step 1: Get Fly VPN
Step 2: Using free trial accounts (listed on the right side on the free trial page) login to Seoul VPNs (It's in Korea, for those who did not like to study geography).
Step 3: Fly VPN might ask you to install some drivers (seems important)
Step 4: once it confirms you're connected start origin - this may take a while.
Step 5: once you successfully log in, enjoy!
Step 6: once the preload is availabe, simply start it and wait for the download to begin
Step 7: once the downloading has started, close origin and log out from fly VPN - from now you can continue downloading using your normal network
