Do not fill this thread with chat about the MM update. We have a thread for that already. This is only a repository for the URLs.
If you are in possession of an official URL link please post it here or PM it to me. That is the preferred method to share the OTA download. If that's not possible for one reason or another, any dropbox, google drive, mega, etc. link to the zip file will do just fine. Please do not rename, repack, or edit your OTA zip in any way. We don't want to break the signature...if you do stock recovery won't flash it.
Here is a guide to capture your URL should you get the notification. Please remember to start logcat BEFORE clicking download.
If you are unable to capture the URL you can find the update .zip file in the /cache directory of your device. You must be rooted to get it, and being rooted will not stop you from being able to download the update. You just can't flash it from a rooted device.
