The current firmware of Nexus 5 is 5.0.1, but you can start upgrading your phone manually to the latest version Lollipop 5.1. The upgrades includes “on-body detection” and HD voice compatibility.

To start upgrading, you need to download the following:

2. Unzip the “hammerhead-lmy47d-factory-6c1ad81e.tgz” to “C:\nexusupdate”.

3. After unzip, you will get a file called “hammerhead-lmy47d-factory-6c1ad81e”, rename the file to “hammerhead-lmy47d-factory-6c1ad81e.tar” and unzip it again in “C:\nexusupdate”. You will get a folder called “hammerhead-lmy47d”

4. Now unzip the “” to the directory “C:\nexusupdate\hammerhead-lmy47d”.

5. Next is we need to unzip the “” to “C:\nexusupdate\hammerhead-lmy47d”

5. Once done.. Open “Command Prompt (Admin)”

6. On CMD, type the following command

cd nexusupdate
cd hammerhead-lmy47d
fastboot oem unlock
