Thanks to XDA-Developers and other Android communities, OTA links for several devices have now been captured for you to sideload. The ones that are available so far are listed as follows:
Note: You’ll need to make sure all security patches are installed prior to sideloading any OTA.
If you haven’t received an OTA yet, you might have to wait up to two weeks because the rollout is based on your region. If you’re extremely impatient like me, you can always download and flash the factory images provided by Google.
