He offered some people to whitelist their Imei to get the update quickly.
Is there a way to download it (will reset the phone though)? If you keep trying, I think the update server just ignores your imei after a while. some servers used to do that.
You can try this link if you like. I am not ready to try it myself. If you do let me know how it went.
