Two Efficient Methods to Update Android from 5.1 Lollipop to 6.0 Marshmallow

With backups at hand, you can now start upgrading Android Lollipop to 6.0 Marshmallow without worrying about data loss. Here, we introduce you to two effective ways to update your Android to the latest OS.

Option 1: Upgrading from Android Lollipop to Marshmallow via OTA (Over-the-Air) update

An "over-the-air" (OTA) update is the most recommended method for updating the Android OS, as it is incredibly straightforward and quick, and anyone can manage it easily.

Step 1. Open "Settings" on your Android phone;

Step 2. Under "Settings," look for the "About phone" option. Tap "Software update" to check for the latest Android version. This step is crucial, and you must update your phone to the latest Android Lollipop version before proceeding with the Marshmallow upgrade. This implies that your device should be running Android 5.1 or higher to smoothly update to Android 6.0 Marshmallow.

Step 3. Once downloaded, your phone will reset and boot into Android 6.0 Marshmallow.

Option 2: Force the Android Marshmallow update using a factory image

Using an Android factory image will wipe all the data, so again, make sure you've performed backups using tools like MobiSaver. Note that this process is intended for advanced users and is best done on Nexus devices.

Step 1. Download and install the latest Android SDK on your Windows computer;

Step 2. Add the SDK folder to the PATH: My Computer > Properties > Advanced system settings > System Properties > Advanced > Environment Variables;

Step 3. Enable USB debugging;

Step 4. Download the factory image for your specific device on your Windows computer, then connect your Android device to the computer via USB;

Step 5. Boot your phone into fastboot mode by holding down the Volume Up, Volume Down, and Power buttons together while turning on your device;

Step 6. Open a command terminal on your computer and run "flash-all.bat" to install the necessary files and operating system onto your phone.

Step 7. Afterward, Google advises you to lock your phone's bootloader for security purposes. To do this, restart your phone back into fastboot mode while it's connected via USB, and then execute the command "fastboot oem lock" in a terminal window on your computer.

These are two ways to upgrade Android from Lollipop to 6.0 Marshmallow available at the moment. Hope you can perform a secure update with the assistance of Android MobiSaver and a complete update with the guide mentioned above.
