How to Upgrade Your Galaxy Note 4 to Android Marshmallow 6.0

Upgrading your Galaxy Note 4 to the latest Android OS, Marshmallow (Android 6.0), is a straightforward process with official channels, or an option if the official update is not available, a more technically demanding custom ROM installation. This guide will walk you through both methods, ensuring you have a reliable and secure experience.

Official Upgrade if Available

The first and safest method to upgrade your Galaxy Note 4 to Marshmallow OS is through official channels. To follow this path, make sure you are up to date with all available system updates.

Check for Updates

Go to Settings. Tap on About Phone. Scroll down and tap on Software Update or Check for Updates, if available.

If an official update is available, follow the prompts to download and install it. If not, proceed to the next section.

Using Samsung Smart Switch

Download and install Samsung Smart Switch on your computer. Connect your Galaxy Note 4 to your computer using a USB cable. Open Smart Switch and check for available updates. If Marshmallow is available, you will be prompted to install it.

Custom ROM Upgrade

If the official update is not available, you can choose to install a custom ROM. This process requires some technical knowledge and may void your warranty. Here’s a general guide on how to proceed:

Backup Your Data

Before proceeding, make sure to back up all important data. This process may erase everything on your device. Use cloud services or a desktop backup software for safe storage.

Unlock the Bootloader

To enable Developer Options, go to Settings and tap on About Phone. Tap the Build Number seven times until Developer Options appear. Enable USB Debugging and OEM Unlocking in Developer Options.

Install a Custom Recovery

Download a custom recovery like TWRP (Team Win Recovery Project). Use ADB (Android Debug Bridge) and Fastboot commands to flash the recovery image onto your device. The commands typically look like this:

Bash code:

sudo adb reboot bootloader
sudo fastboot flash recovery path_to_recovery_

Download a Marshmallow ROM

Find a stable Marshmallow ROM for the Galaxy Note 4 like LineageOS or others. XDA Developers is a reputable source to start from. Download the ROM and any necessary GApps (Google Apps) package.

Flash the ROM

Boot into recovery mode by holding Volume Up, Home, and Power buttons simultaneously. In TWRP Recovery, select Wipe and perform a factory reset. Go back to the main menu and select Install. Choose the downloaded ROM file. After the installation, flash the GApps package if necessary.

Reboot Your Device

Once everything is installed, reboot your device. Make sure your device is charged to avoid unexpected shutdowns during the process.

Important Notes

Warranty

Using custom ROMs may void your warranty. Proceed with caution.

Risks

There’s always a risk of bricking your device when modifying the software. Ensure you follow instructions carefully to minimize risks.

Research

Make sure to read specific guides and user feedback for the ROM you choose to ensure compatibility and stability. This step is crucial to avoid any unforeseen issues during and after the installation.

By following these steps, you can successfully upgrade your Galaxy Note 4 to Android 6.0, ensuring a more efficient and secure user experience. Always prioritize data backup and proceed with caution during the upgrade process.
