From Android 5.0, the mobile market quickly moved to Android 5.0.1 to Android 5.0.2 and now we’re on to Android 5.1.1. Just last week, we learned of several phones running the latest version. There’s the General Mobile 4G Android One phone and several Nexus devices: Nexus 9, Nexus 7, and Nexus 10 (factory images only), Nexus Player.

This week, OTAs for the Nexus 4, Nexus 5, and Nexus 9 have started to roll out albeit not announced formally by Google yet. XDA happened to share the links, all genuine from Google’s servers. If you’re going to install the update, make sure system directory is stock in order for the flash work. Basic steps to flashing are as follows: (1) add file to ADB directory; (2) reboot into recovery mode; (3) enable ADB sideloading; (4) connect your device; (5) choose “adb sideload filename.zip”.

As with all similar releases, we advise that you download these files at your own risk. Here are the links:

Nexus 4
5.1.1 OTA LMY 47V

Nexus 5
5.1.1 OTA LMY48B
5.1.1 OTA LMY47B

Nexus 9 (LTE)
LTE 5.0.2 OTA LRX22L
LTE 5.1.1 OTA LMY47X

Added information and more details on device-specific troubleshooting are available in the Forums. We’re assuming you know how to do these flashing, downloading, and installation. If you don’t, we suggest you wait for the official OTA.
