The official Android 5.1.1 Lollipop (build number LMY48I) has been released and it’s now available for all Nexus 5 devices.
The Android 5.1.1 Lollipop firmware comes with many bug fixes such as the major bug fix for the StageFright vulnerability. The Nexus 5 device that ran on older Android 5.x builds was vulnerable to this MMS hack that scared a lot of people.
If you haven’t heard of the MMS hack yet, then you should know that anyone could use it to get full access to your Nexus 5. To do this, hackers just needed to send you a MMS message that contained a photo or video with a malicious code. However, you don’t have to worry about this problem anymore, as the Android 5.1.1 Lollipop – LMY48I has fixed it and it will not execute any malicious code anymore once you receive a MMS.
Updating Nexus 5 to Android 5.1.1 Lollipop LMY48I
First of all, you should know that your Nexus 5 device must run on Android 5.1.1 Lollipop LMY48B firmware build or else you will not be able to install the LMY48I version. To check what version your Nexus 5 is currently running on, go to Settings->About Phone.
HINT: In case you are running a custom ROM on your Nexus 5, then this tutorial is not going to work.
Installing Android 5.1.1 Lollipop LMY48I on Nexus 5
First of all, make sure that the USB debugging option is enabled (you can find it in Settings->Developer Options). In case you can’t see the Developer Options tab, you will need to enable it by going to Settings->About Phone and tap 7 times on the build number section.
After that, make sure that you have at least 60% of battery left on your device and download the Android SDK from developer.android.com. Now, install Android SDK on your computer and launch it (make sure that you install all SDK packages and drivers). Go to the location where you’ve installed Android SDK and find the “platform-tools” folder and leave it open, as this will be the place where you will put the update file.
Now, download the Android 5.1.1 Lollipop LMY48I file from the internet and rename the file to update.zip. Move the update.zip file to the platform-tools folder and switch off your Nexus 5.
Next, you will need to boot the Nexus 5 in recovery mode, and select “apply update” from the adb option. Then, you will need to connect the Nexus 5 to your computer via the USB cable and launch the command prompt on your computer. While in the command prompt on your computer, head to the location where you’ve installed Android SDK and enter “platform-tools” folder. Now, type the command “adb sideload update.zip and the Android 5.1.1 Lollipop LMY48I installing process will start. Let the installation complete and you will notice that the Nexus 5 will reboot in normal mode.
Congrats, now you run Android 5.1.1 Lollipop LMY48I on your Nexus 5 and you don’t have to worry about the MMS bug anymore.
