The Google Nexus 5 is finally witnessing the Android 5.0 Lollipop rollout over the air as a system update coming into the notifications panel. As you know, these role in phases to all people with the device, therefore some will see it arriving today and others will not be so lucky. If you want to skip the waiting process and update your handset to the official Lollipop software you can flash the file manually after the steps below.

The build number for the official Android 5.0 is LRX21O and it comes at around 400 MB. That means it is a large update and it will take a long time to finish upgrading if you are using the Home WiFi. We suggest completely skipping downloading using the mobile data plan since it is a long-awaited upgrade and a great deal of people will be installing this one. Skip the mobile data connection since the high traffic will result in a less stable experience that is prone to freezing. That advice is for those looking to install the OTA where people here don’t need to worry since we are flashing the firmware direct.

Nexus 5 Lollipop

The guide we are presenting to you today teaches how to install the Nexus 5 LRX210 hammerhead factory image provided by Google. That’s the build number for the official update so you need not worry about if this is the genuine product.

You should note that there’s no reason to install it this way unless you are wishing to skip the waiting line. The same build will eventually arrive to your phone as an automatic OTA update. It might come in the next 30 minutes or the next 30 hours. Nobody knows the exact sequence for the staged rollout apart from the folks in the Mountain View complex and the phone carrier networks.

Do not try using these steps for any other device under the Nexus range including the Nexus 7, Nexus 4, Nexus 9 or 10. You run the risk of soft-bricking the handsets if you attempt to install inappropriate files.

The steps we are listing below are for advanced Android users only. We previously mentioned that it’s for those who are looking to fast forward the situation. While that’s correct, if you aren’t an Android enthusiasts with experience in flashing or rooting a device then it’s a great idea to just wait for the official over the air signals.

Unlike other flashing tools, following this procedure will wipe all the current data stored on the phone. That means unless you backup the EFS, call logs, SMS texts, pictures, videos, music files and all other data they are lost by the time the steps are finished. You will be left with a phone that appears like it’s just come out of the box. If you already have your preferred method for backing up, go ahead and do that. Otherwise you want to install the Helium for Android application available from the Google Play Store to make copies of the market applications and sync the phone contacts. Use SMS backup+ also available from the Play Store for those messages you don’t want to lose. There are many other options available such as G Cloud Backup, Holo and more.

You must stopover at the Developer Options menu and enable USB Debugging Mode from the Settings menu. Now you can successfully connect the phone on the computer. Correspondingly, you must have a computer, notebook or laptop readily available to use with the steps. Transferring files from the computer first is the safest way to go about this business. That’s why we always chose that path.

Temporarily disable any security programs you might have running from the computer such as Microsoft Security Essentials. Furthermore, stop the security applications running on the phone if you are using antivirus for the Android operating system.

You must use a Windows-based PC ranging from Windows XP through to Windows 8.

The Nexus range always comes with USB charging as a default stock feature. That means when we plug the handsets into the computer with the USB wire, they will automatically start charging the device’s battery up since it’s connected with a power source. That means theoretically you should end up with more power than when you started if you are connected to the computer for most of the guide. Nevertheless, it’s a great idea to reserve some power just in case this feature isn’t working. Sometimes it can play up for certain devices. If you know USB charging isn’t working for you then you want to save at least 50% battery charge. Double check this by turning the phone on, navigating to the status bar and observing the battery icon.

Make sure you have the up-to-date USB Drivers ready for flashing on the computer. That way we can connect without any hassles.
