[Nexus 5 Original Android Development] saeedashifahmed:
You can now download Android 5.0 Lollipop (Developer Preview) build LPX13D for the Nexus 5 and Nexus 7. After the initial preview build, LPv79, this is now the second and final developer preview before the official update will be released next month. This Preview Image of Android 5.0 Lollipop contains many of the major enhancements that were teased at Google I/O held previously this year. LPX13D will be bringing the final transformed stock applications and will also be completing the design overhaul. This is a greater update than the initial preview build, LPv79. There is one thing to note, Google is still not regarding this as a complete final upgrade for the masses but it is targeting it towards the developers so that they can test out their apps. You can manually update Nexus 5 to Android 5.0 LPX13D developer preview factory image from the tutorial below. The only catch is that if this will be your first time playing around with a factory image, you might have to unlock your bootloader first before continuing – which means wiping all of your phone data.

How to Install Android 5.0 LPX13D Preview on Nexus 5

We have put together a detailed step-by-step instructions guide on how to install Android 5.0 Lollipop (LPX13D) Developer Preview on Nexus 5 using the preview image provided by Google. This tutorial is for beginners who are not used to playing around with official factory images by Google for their Nexus devices.

Please make sure your phone fulfills all the requirements and you read the entire tutorial once before actually performing it on your device.

Just To Remember:

This tutorial is only for Lg Nexus 5 and I am not sure if it will work on the other variants of this tablet.

Your tablet can be on any previous Android version or even on a custom ROM. It doesn’t matter at all. This tutorial will still work for installing Android 5.0 Lollipop.

Enjoy Android 5.0 on your device and let us know your review about it!

NOTE: Installing Android 5.0 LPX13D Lollipop Developer Preview will WIPE / DELETE / ERASE everything from your tablet if your bootloader is not already unlocked. Please make sure you have a backup of all the data. Read: How to Backup Android Apps and Other Data.

Complete Step-By-Step Instructions:

Step 1 - Download Android 5.0 Preview Image (hammerhead-lpx13d-preview-f7596f51) for Nexus 5 on your PC, if you haven’t already.

Step 2 - Connect your Nexus 5 to your computer using the USB cable.

Step 3 - Please make sure Fastboot is configured and properly installed on your computer. How? See here: How to Set Up ADB and Fastboot with Android SDK.

Step 4 - Turn OFF your tablet.

Step 5 - Get into the Fastboot/Bootloader Mode on your device. Turn ON the tablet while pressing and holding the Volume Up + Power buttons till you see the Fastboot menu and START on top.

Step 6 - Now extract the downloaded file anywhere in your computer. Go to the folder hammerhead-LPX13D and then copy/paste all the files to your Fastboot directory.

Note

: If you followed our tutorial on setting up Fastboot on your computer, there is a 99% chance your Fastboot directory will be the platform-tools folder in your Android SDK directory.

Step 7 - From the factory image files in your Fastboot directory, do the following depending which OS you are on:

On Windows: Run the file “flash-all.bat”.

On Mac: Run the file “flash-all.sh” using Terminal.

On Linux: Run the file “flash-all.sh”.

Step 8 - That’s pretty much that you had to do for flashing the stock factory image on your Nexus 5. Now wait and watch as the process is completed — or follow the on-screen instructions on your tablet if in case you have to unlock the bootloader.

Step 9 - After the installation completes, your tablet will boot now and it might take about 5 minutes to boot on your first time. So, please wait with patience!

That’s it! Your Nexus 5 should now have the official Android 5.0 LPX13D Lollipop Developer Preview update installed on your phone! Go to Settings >About phone to verify.

Have fun playing with the new Android 5.0 Lollipop. All the instructions are clearly given above, but if you have any issues, please let us know.
