Android 5.0 LRX21O Lollipop is now available for the Nexus 5. You can now download the official factory image from Google Developers and flash it on your phone. This new update comes in just after a Twitter announcement by the official Android account that the update has just started rolling out via OTA (over-the-air) and we should be getting it on our Nexus devices very soon. The OTA is now available for the Nexus 5 running KitKat to be upgraded to Lollipop. For others, no matter which Android version you are currently, factory images can be installed over any thing. The exact Android 5.0 build is LRX21O for Nexus 5. You can manually update Nexus 5 to Android 5.0 LRX21O factory image from the tutorial below — and root Nexus 5 on Android 5.0.

Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. See below for some tips on how to backup data:
- Backup your Apps. How? –> How to Backup Android Apps.

- Backup Contacts, Gmail and Google Data. How? –> Sync with Google Sync.
- Backup Call History. How? –> How to Backup Call History.

- Backup APN Settings: GPRS, 3G, MMS Settings. How? Note down everything from: Settings > Wireless & Networks (More…) > Mobile networks > Access Point Names.
If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up.
A few more optional tips that you should remember:
1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich and Lollipop.
2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?
4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend not to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.
