Google Nexus 7 receives Android 5.0.2 Lollipop Factory Images and OTA update

Google Nexus 7 receives Android 5.0.2

The original Google Nexus 7 is currently receiving the Android 5.0.2 Lollipop update. Google has posted the factory image for the latest version of Android, and the OTA update is also being sent out for the Nexus 7 tablet.

It was just last week, that the Nexus 5 received the Android 5.0.1 factory image. A few days before that, T-Mobile started rolling out the Android 5.0.1 update to its Nexus 5 and Nexus 6. The same update was pushed out to the Google Play editions of the HTC One M7 and HTC One M8 earlier this month.

The 2012 Nexus 7 seems to be skipping Android 5.0.1 in favor of the newer build. The Android 5.0.2 update brings the LRX22G build, and will reportedly fix an issue that the Nexus 7 has with storage. It also fixes an issue that deals with the alarm on the slate.

Since the OTA update is rolling out for the Nexus 7, users are advised to directly update OTA. The Factory Image is generally used by those who customize their device with ROMs and MODs, and wish to return to the default state. Factory Images can also be used by those who have rooted their devices, and wish to obtain updates directly from Google instead. In any case, you can download the factory images for your Nexus 7 using the following link.

How to install a Factory Image on your Nexus device

If you have rooted or flashed a custom ROM on your Nexus device but now want to go back to complete stock, simply follow the steps below. Do note that the below steps will completely wipe your Nexus of any data, so make backups. Also, you will need to have an unlocked bootloader to flash the factory image.
  1. Download the correct factory image for your Nexus device using the direct links above or from Google's website.
  2. Download and install the Android SDK on your computer. You can also download the required files only using the following links to save some time and space.
  3. Download USB Drivers for Windows if you are using a Windows computer.
  4. If you have the SDK installed head over to adt-bundlesdkplatform-tools to access ADB/Fastboot. If you downloaded the files create a folder under C:android and extract the ADB/Fastboot files into it.
  5. Now extract the factory image you downloaded in Step 1 into the same folder of ADB and Fastboot.
  6. Make sure to install the ADB Driver you downloaded in Step 3.
  7. Now, reboot your Nexus device in bootloader mode. This is usually done by switching off the device, and pressing the Volume down + Volume Up + Power button simultaneously. If that does not work, try the Volume down + Power button combination. After the device has booted into bootloader mode, connect it to your PC.
  8. Open a new Terminal or Command Prompt window, and navigate to the ‘google’ folder that you created in Step 1. Before we start flashing the factory image, we need to make sure that your Nexus device is being detected by the PC.

    If you are using a Mac, then you need to prefix a “./” before every Fastboot command. So, the above command will look something like this on a Mac -:
    ./fastboot devices
    The above command should confirm if your device is indeed being detected by your PC or not. If it is, then proceed to the steps below. If not, repeat the steps above again. Make sure that you have properly installed the drivers and are inside the correct folder.
  9. If you are running Windows, copy-paste the following command in the command prompt window:
    On a Mac, copy-paste the following command:
    The script will then automatically flash the full factory image on your Nexus device. Once the factory image has been flashed, your device will automatically reboot. Keep in mind that the first boot might take some time so please be patient.
If you have issues using the flash-all command, including the "missing system.img" error, you may have to flash each of the files in the factory image manually. The command to manually flash a partition via fastboot is “fastboot flash partition filename.img”. In the factory image that you extracted in Step 1, you will notice there is another ZIP file. Extract the contents of that ZIP file inside the ‘google’ folder.
Now, its time to manually flash the partitions to your Nexus device. We first need to start with the bootloader.
fastboot flash bootloader filename.img
Then, we will flash all other partitions. They don’t necessarily need to be in the same order as I have listed them below. The names of the image files in the factory image will clearly indicate the partition they are intended for as well.
fastboot flash boot filename.img
fastboot flash radio filename.img
fastboot flash recovery filename.img
fastboot flash userdata filename.img
fastboot flash system filename.img
If you want to relock the bootloader of your device after flashing the device, put the device back in fastboot mode. Then type in the following command in the Terminal or Command Window you had opened earlier:
fastboot oem lock
This will re-lock the bootloader of your Nexus device, restoring your warranty and putting the device back to complete stock
