I was able to "push" my v14.1 lite download when it didn't want to on its own.
Obviously if there is no download available for your VIN, then nothing will get it sooner. But in my case, it was apparently available and my actions triggered it to download sooner. How much sooner? I don't know. :)
Mine was sticking on v14.0 and not upgrading to 14.1. '22MYLR. I finally turned on Advanced updates (doubt this did anything) a few hours beforehand and when checking again there was no update. I then connected to my phone hotspot and enabled automatic updates and it instantly found the newest version and allowed the download, albeit the slowest update download, ever. haha. (Checksum pauses up the wazoo)
Maybe it might get you pushed up a few hours, so might be worth a shot? I was lucky in that my download and update finished 5 minutes before a really long drive and I was able to put 14.1 through the gauntlet, which it did wonderfully.
