GSI (Generic System Image) is a system image for Android phones. It is a pure Android implementation with stock unmodified AOSP code. It can be installed and run on every phone that is Treble-compatible. Now that Google has officially released the latest OS version, there are also Android 11 GSI images. The Samsung Galaxy Note 20 is a Treble compatible device, so you can download and install an Android 11 GSI image on it.

Below you will find a detailed guide on what files you need to download, what are the requirements for you to flash the image, and also all the necessary steps for you to successfully update your Galaxy Note 20 and its siblings to Android 11.

How To Install Android 11 GSI on Samsung Galaxy Note 20 and Note 20 Ultra


The process of installing a GSI image might be confusing for users that have never flashed a custom ROM before. For this tutorial, you need a custom recovery, and you need to unlock the bootloader of your phone. NaldoTech shall not be held responsible if you damage or break your phone by following this guide. Please proceed at your own risk.

Supported Models

The good thing about GSI images is they can be installed on any Android device. However, there are a few requirements. First, you need a custom recovery, and two, you need to have a phone whose bootloader can be unlocked.

In the case of the Samsung Galaxy Note 20 and Note 20 Ultra, there are two variants with two different chipsets. One with Exynos and one with Snapdragon. If you have the Exynos variant, you can go ahead and follow the tutorial. However, if you have a Snapdragon variant, you can go ahead only if you have the Chinese version of the phone. But if you have an American (US) variant, you cannot proceed, because the bootloader cannot be unlocked.

Do not try this on the US Snapdragon variant. The bootloader cannot be unlocked because carriers do not allow it. If you try anything from this tutorial on your US Snapdragon phone, you will brick it.
