How to update your Nexus to Android 5.0 Lollipop manually

In the next practical tutorial I am going to teach you download Android 5.0 Lollipop factory image just published by Google on their own web page for the different Nexus models, and update these to this latest version of Android 5.0 Lollipop Manually through the command line of our personal computer whatever operating system you have.

You must bear in mind that This update process will erase all the data and applications that we have installed on our Nexus, so I recommend that before starting make a backup of everything you need to keep.

To begin we must have downloaded the Android SDK for our operating system, from this page you will be able to download it and save on your personal computer whatever the operating system. In this tutorial, let's focus the explanation on the Windows operating system since it is the system with more users who demand the explanation.

Update your Nexus 5 or Nexus 7 to Android 5.0 manually

The image is from a file and does not correspond to Android 5.0, it is an image only to guide you in the process

Once Android SDK downloaded, we are going to unzip it in drive C and into the folder platform-tools we are going to unzip the factory image based on our Nexus model. Here are the direct links to download Android 5.0 Lollipop according to the terminal model that we have, for the moment, the compatible terminals are the following:

Once unzipped the factory image in the platform-tools folder Android SDK, we are going to open a command window in the aforementioned path, we can do it easily using the key combination SHIFT + right mouse click.

Now it will only be enough connect the Nexus device that we want to update to Android 5.0 Lollipop, turning it on in mode bootloader and always having USB debugging enabled from the developer settings:

The first command to be used will be the one that will make the Nexus reboot in mode. bootloader:

adb reboot bootloader

If we want to, we can skip this step and restart the Nexus in bootloader mode by combining buttons Volume Down + Volume Up + Power.

Now we will have to unlock bootloader using this command:

fastboot oem unlock

Logically you can skip this step if we already have a terminal with the bootloader unlocked.

Now it will only be enough for us to write the command that will flash the Nexus and it will update them to Android 5.0 Lollipop. The command is as follows:

Flash-all.bat

When the firmware finishes flashing, the device will restart and in the command window it will indicate that we can now disconnect the Nexus, which, as if by magic It will already be updated to the latest version of Android 5.0 Lollipop.

Finally, if you want to lock the bootloader again for safety, you will only have to restart in bootloader mode using the command:

adb reboot bootloader

And then block the bootloader again with the following command:

fastboot oem lock

Easy right? This process explained here is valid for all Google Nexus terminalsThe only thing that varies is the image file to download, which has to be that of the specific model of your terminal. From this link you will find the factory images of all the Nexus terminal models on the market and all versions of Android existing to date.
