Summary
Upgrading an Android smartphone or tablet from 5.1 or higher Lollipop to Marshmallow can lead to data loss due to the update process.
Android 6.0 Marshmallow is available on certain Android devices, but users who upgraded from Lollipop to Marshmallow have reported losing contacts, photos, messages, and other multimedia files.
To ensure your data is protected during the Android 6.0 Marshmallow update, it's essential to backup your Android to PC. This process can be time-consuming, but using a reliable backup and recovery tool like Qiling MobiSaver for Android can make it easy and efficient. By taking this precaution, you can avoid losing your precious data and ensure a safe update experience.
Step 1. Connect Android Phone to a Windows computer.
Step 2. Run Qiling MobiSaver to scan all data on Android.
Step 3. After the scan, save Android data to the computer.
With backups in hand, you can now upgrade Android Lollipop to 6.0 Marshmallow without worrying about data loss. There are two effective ways to do this: you can either use a software tool or perform a manual upgrade, both of which are detailed methods that allow you to successfully transition to the latest OS.
Updating Android OS through an "over the air" (OTA) update is the most recommended method, as it is quick, easy, and hassle-free for everyone to handle.
Step 1. Open "Settings" on your Android phone;
Step 2. To update your Android phone to Marshmallow, go to the "Settings" app, select "About phone", then tap "Software update" to check for the latest version of Android, ensuring you're running Android 5.1 or higher before proceeding.
Step 3. Once downloaded, your phone will automatically reset and install Android 6.0 Marshmallow, then launch into it.
Using an Android factory image will wipe all the data, so make sure you've done backups. This process is for advanced users and better on Nexus devices.
Step 1. Download and install the latest Android SDK on your Windows computer;
Step 2. To add the SDK folder to the path, follow these steps: Go to My computer > Properties > Advanced system settings > System properties > Advanced > Environment variables; In the 'System variables' section, scroll down and find the 'Path' variable, then click 'Edit'; In the 'Edit environment variable' window, click 'New' and enter the path to the SDK folder, then click 'OK' to close the window. This will add the SDK folder to the system's PATH environment variable.
Step 3. Enable USB debugging;
Step 4. Download the factory image for your device on your Windows computer and connect your Android to the computer via USB. Then, open the command prompt and navigate to the directory where the factory image is stored.
Step 5. To boot your phone into fastboot mode, hold down the volume up, volume down, and power buttons simultaneously when turning your device on. This will initiate the boot process in fastboot mode, allowing you to access and interact with the device in this mode.
Step 6. Open a command terminal on your computer and execute "flash-all.bat" to install the necessary files and OS onto your phone.
Step 7. Google recommends locking your phone's bootloader for security after you've completed the process, which involves rebooting your phone into fastboot mode while connected via USB and then executing "fastboot oem lock" from a command terminal on your computer. This step is essential to ensure the security of your device.
These are two ways to upgrade Android from Lollipop to 6.0 Marshmallow available at the moment. Hope you do a secure update with the help of Qiling MobiSaver for Android and a complete update with the guide introduced above.
