Google has issued a brand new Android 5.1.1 Factory Image file that should patch the StageFright Security bug forever. If you want to install a clean Lollipop OS on your tablet, then you should check all the info listed in this post.

How to Install Android 5.1.1 LMY48M Factory Image for Google Nexus 10:
Now, if your tablet runs a 100% stock Android 5.1.1 LMY48I Lollipop build, then you can install the LMY48M firmware without losing any files.
Note, if your tablet sports a custom ROM or you’ve done any other modifications to it, then you cannot avoid the ‘factory reset’ process.
Here’s what you need to do in order to avoid the ‘factory reset’:
- go to the ‘platform-tools’ folder where you have extracted the files from the Factory Image archive.
- find the flash-all.bat script and open it in a file editing tool.
– that is the Android 5.1.1 factory image installer.
- now, locate the -w characters and delete them both.
– those two characters are the ones triggering the ‘factory reset’ process.
- save the changes done to the factory image installer and continue to the next part of this post.
Make sure to setup the Android SDK on your computer, as it will allow the PC to detect your device.
Here’s how to setup the Android SDK:
- download the SDK installer from here.
- install the SDK on your computer and then continue to the next step.
- locate the SDK Manager exe and launch it.
- now you should install all the SDK packages and drivers.
- after the installs are done you can look for the ‘platform-tools’ folder.
– leave this folder opened, as that’s where you will need to place all the installation files.
- also, download and install the Google USB drivers from here.
– the Google usb driver can be used in case the tablet is not detected by your PC.
Now you can begin the installation process of Android 5.1.1 Factory Image build LMY48M:
- Download the LMY48M Android 5.1.1 factory image from here.
- Extract the contents comprised within the archive.
- Move all the extracted files in the SDK directory under ‘platform-tools’ folder.
– if you don’t put the files in that folder the flashing process won’t work.
- Switch off your Nexus 10 now.
- Boot it in Bootloader Mode.
- Connect it to your PC via usb cable.
– make sure that your PC has detected the tablet before continuing to the next step.
- For the new factory image to start installing all of its new Android 5.1.1 LMY48M files you should launch the flash-all.bat script file.
- Confirm the installation.
– don’t press any buttons until the flashing process is done.
- When the install is complete you will see a confirmation alert and you can unplug the device from PC.
- Now wait until the first boot process of Android 5.1.1 LMY48M is done.
- Use your default Google account data in order to regain complete control over your device once again.
