How to Download and Install Android 5.1.1 Lollipop OTA Zip File on Your Computer

Android 5.1.1 Lollipop is the latest version of the Android operating system that brings many improvements and bug fixes to your device. If you want to update your device to this version, you can either wait for the official OTA (over-the-air) update from your manufacturer or carrier, or you can manually download and install the OTA zip file on your computer.

In this article, we will show you how to download and install the Android 5.1.1 Lollipop OTA zip file on your computer using a simple method. This method works for most devices that are compatible with Android 5.1.1 Lollipop, but you should always check the compatibility of your device before proceeding. You should also backup your data and charge your battery before starting the process.

Step 1: Download the Android 5.1.1 Lollipop OTA Zip File

The first step is to download the Android 5.1.1 Lollipop OTA zip file for your device from a reliable source. You can find the links for various devices on websites like XDA Developers or Android Police. Make sure you download the correct file for your device model and region.

Once you have downloaded the file, save it to a convenient location on your computer. Do not extract or rename the file.

Step 2: Connect Your Device to Your Computer

The next step is to connect your device to your computer using a USB cable. Make sure you have enabled USB debugging mode on your device. To do this, go to Settings > About Phone > Tap on Build Number seven times > Go back to Settings > Developer Options > Enable USB Debugging.

Once you have connected your device, you should see a notification on your device that says “USB debugging connected”. If not, try reconnecting or changing the USB port.

Step 3: Install ADB and Fastboot Drivers on Your Computer

The third step is to install ADB and Fastboot drivers on your computer. ADB and Fastboot are tools that allow you to communicate with your device from your computer and perform various commands.

You can download and install ADB and Fastboot drivers from here: https://developer.android.com/studio/releases/platform-tools.html

Once you have installed the drivers, open a command prompt window on your computer and navigate to the folder where you saved the OTA zip file. To do this, type “cd” followed by the path of the folder. For example, if you saved the file in C:\Downloads, type “cd C:\Downloads”.

Step 4: Reboot Your Device into Recovery Mode

The fourth step is to reboot your device into recovery mode. Recovery mode is a special mode that allows you to perform various actions on your device, such as wiping data, installing updates, or restoring backups.

To reboot your device into recovery mode, type “adb reboot recovery” in the command prompt window and press enter. Your device should reboot and show a screen with an Android logo and a red exclamation mark.

To access the recovery menu, press and hold the power button and volume up button together for a few seconds. You should see a menu with several options.

Step 5: Apply Update from ADB

The fifth and final step is to apply the update from ADB. This means that you will send the OTA zip file from your computer to your device and install it using ADB.

To do this, select “Apply update from ADB” from the recovery menu using the volume buttons to navigate and the power button to confirm.

Your device should show a message that says “Now send the package you want to apply to the device with ‘adb sideload ‘”.

On your computer, type “adb sideload” followed by the name of the OTA zip file in the command prompt window and press enter. For example, if the file name is “update.zip”, type “adb sideload update.zip”.

The process should start and show a progress bar on both your device and computer screens. Wait until it finishes and shows a message that says “Install from ADB complete”.
