Installation Guide

This guide provides comprehensive instructions for installing SukiSU-Ultra on your Android device. Please follow the steps carefully.

Prerequisites

Before you begin, ensure you have the following:

  • A compatible device. Check the Compatibility Guide for details.
  • Unlocked bootloader.
  • Custom recovery installed, such as TWRP.
  • Basic knowledge of flashing custom ROMs and kernels.
  • Your device's kernel source or a compatible pre-built kernel.

Installation Methods

There are several ways to install SukiSU-Ultra, depending on your device and preference.

Method 1: Using Pre-built GKI Packages

This is the recommended method for devices with Generic Kernel Image (GKI) 2.0, such as many Xiaomi, Redmi, and Samsung models.1

Steps:

  1. Download GKI Build: Visit our resources section to find the appropriate GKI build for your device's kernel version. Download the .zip file that includes AnyKernel3 in its name.
  2. Flash via Recovery:
    • Boot your device into TWRP recovery.
    • Select "Install".
    • Navigate to the downloaded AnyKernel3 zip file and select it.
    • Swipe to confirm the flash.
    • Once flashing is complete, reboot your system.
  3. Verify Installation:
    • Install the SukiSU-Ultra Manager app.
    • Open the app and check if root access is granted and working correctly.
    • You can also verify the new kernel version in your device's settings.

::: details File Format Guide The .zip archive without a suffix is uncompressed. The .gz suffix indicates compression used for specific models. :::

Method 2: Custom Build for OnePlus Devices

For OnePlus devices, you'll need to create a custom build.

Steps:

  1. Gather Device Information: You will need:
    • Your kernel version (e.g., 5.10, 5.15).
    • Your processor's codename.
    • The branch and configuration files from the OnePlus open-source kernel repository.
  2. Create Custom Build: Use the link in our resources section to generate a custom build with your device's information.
  3. Flash the Build:
    • Download the generated AnyKernel3 zip file.
    • Boot into recovery.
    • Flash the zip file.
    • Reboot and verify the installation.

Method 3: Manual Kernel Integration (Advanced)

This method is for advanced users who are building a kernel from source.

Integration Scripts:

  • Main Branch (GKI):
    curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
    
  • Non-GKI Branch:
    curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s nongki
    
  • SUSFS-Dev Branch (Recommended):
    curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s susfs-main
    

::: warning Required Kernel Configs For KPM support, you must enable CONFIG_KPM=y. For non-GKI devices, you also need to enable CONFIG_KALLSYMS=y and CONFIG_KALLSYMS_ALL=y. :::

Post-Installation

Maintaining Root After OTA Updates

To keep root access after an Over-the-Air (OTA) update, follow these steps ==before rebooting==.

  1. Flash to Inactive Slot:
    • After the OTA update is downloaded and installed, do not reboot.
    • Open the SukiSU-Ultra Manager.
    • Go to the flashing/patching interface.
    • Select your AnyKernel3 kernel zip file.
    • Choose to install it to the inactive slot.
    • Once flashed, you can safely reboot.
  2. Alternative: LKM Mode: You can also use LKM mode to install to the unused slot after an OTA.

::: tip For non-GKI devices, the safest method to retain root after an OTA is to use TWRP to flash the kernel again. :::

Verification Checklist

After installation, please verify the following:

  • Manager App: The SukiSU-Ultra Manager app opens and shows a successful root status.
  • Root Access: Root checker apps confirm that root access is working.
  • Kernel Version: The kernel version in Settings > About Phone reflects the SukiSU-Ultra kernel.
