Last week Google announced that Lollipop will come to most Nexus devices in the coming weeks. If you like to get the latest from Google, you know that “coming weeks” could be a pretty long wait. Cut the line and install the over-the-air (OTA) update by following our quick guide.
This guide assumes you already have the ADB tools (for whichever operating system you’re using) installed on your computer. If you don’t know how to do this or what this is, this guide probably isn’t for you. If you need the ADB tools, head over and download the Android SDK. Downloading the SDK and making sure ADB is correctly set up is probably the hardest part, but this guide is for those who have already done this.
Download the OTA
The first step to updating to Lollipop using OTA files is to actually download the proper OTA file for your device. The list below are download links straight from Google (hat tip to Android Police for putting these together):
Note: If there is more than one download option, that means that there is more than one build of Android KitKat available for your device, and you need to download the one that correlates.
Nexus 5: from 4.4.4 (KTU84P) to 5.0: hammerhead LRX21O from KTU84P from 4.4.4 (KTU84Q) to 5.0: hammerhead LRX21O from KTU84Q
Nexus 7 2013 WiFi: from 4.4.4 to 5.0: razor LRX21P from KTU84P
Nexus 7 2012 WiFi: from 4.4.4 to 5.0: nakasi LRX21P from KTU84P
Nexus 10: from 4.4.4 to 5.0: mantaray LRX21P from KTU84P
Nexus 4: from 4.4.4 (KTU84P) to 5.0: occam LRX21T from KTU84P
Note: Download links for Nexus 7 2012 3G and Nexus 7 2013 LTE aren’t yet available.
Prepare your Device
Once you have the OTA zip downloaded to your computer, reboot your device into its boot loader. To do this, power off your device and power it back on while holding the volume button and the power button down simultaneously. You need to get into the recovery from here. Press the volume button until you see “Recovery mode” then press the power button. This should present you with the below screen.
Lastly, you need to hold the volume up and power button down for three seconds and release volume up to reveal the menu. From that menu, select “apply update from ADB” and plug your device into your computer if you haven’t already.
Install the OTA
Open up the command line on your computer (terminal for Mac, command prompt for Windows) and change the directory to the location of the OTA file (For example: cd /Users/<yourusername>/Downloads/). Now run the command “adb sideload <name of the OTA file>”. The name of the OTA file is going to be a long string of letters and numbers and will end with “.zip.”
Once you see “Install from ADB complete” on screen, simply reboot your device. And once you’ve successfully rebooted, you should have the latest release of Android on your Nexus.
