The rollout for Google's major Android 5.0 Lollipop update continues for devices with manufacturer-altered versions of the operating system. But for the Nexus line, which has pure Android and is the first set of devices in line for Android updates, the next iteration, Android 5.1 Lollipop, has been known about for at least a month now.

Yet not all Nexus devices have received the update, and for some, it appears to be a fix-or-brick situation. Here's the current (messy) Android L update situation for Nexus devices.

Which Nexus Devices Are Up To Date?

With the pace and uneven distribution of Android updates these days, the phrase "up to date" is a pretty relative term.

For example, if you have a Google Play Edition device anywhere, or a T-Mobile Nexus 5 or even Nexus 4, you should be running Android 5.1. The same goes for the Nexus 6 on every available carrier, though on AT&T the Nexus 6 is a bit of a special case that might require some extra steps to ensure the Android 5.1 update gets through (see what I mean?).

Meanwhile, the Nexus 7 (2012 and 2013) should be to date with Android 5.1 -- while the Nexus 9 still has yet to receive an update beyond Android 5.0, though it exists at Google, according to Android Police -- but now it appears those devices desperately need the next update, Android 5.1.1, in order to solve some bricking issues.

What's Next?

Android 5.1.1 is next, according to Android Community. The update isn't likely to be exciting, since all indications are that it's just a bug fix update.

But that update may help out Nexus 7 (2013) users who have been experiencing myriad issues at boot, such as freezing, failure to fastboot, and a spotty record of booting up into recovery -- on top of other more common issues like severe lag and crashing apps. The onset of reports of these problems suggests that Android 5.0 or 5.1 were the culprits, though Android Police argues it may be a deeper, more troublesome issue rooted in ASUS's design of the device itself. 

Nevertheless, when in doubt, update (that is, if you can get your device to turn on long enough to do so). And it appears Google has Android 5.1.1 build number LMY47W ready to go soon for the Nexus 7, at least as it was spotted an a technical Android information posting. 

And if that page is correct, the Nexus 9 will be skipping straight from 5.0.1 to Android 5.1.1 -- which may be a sign that Google knows the Nexus tablets aren't taking to Android 5.1 very well, or may be just a case of convenient workflow.

In either case, Google hasn't officially acknowledged the 5.1.1 strain of Lollipop yet, so we'll have to wait and see.
