Rooting

• Enable developer options and then OEM unlocking.

• Unlock bootloader. This will erase all data on the device.

  fastboot flashing unlock
  fastboot flashing unlock_critical
  

• Disable developer options.

• Install the KernelSU app from KernelSU GitHub releases.

• Download the image-boot file that matches device model and firmware which includes init_boot.img from the releases section.

It provides easy access for downloading the latest Nothing OS firmware to keep your devices up-to-date.

• Feed init_boot.img file to KernelSU app.

  • Or, to do it on a Linux X86_64 computer, download magiskboot-linux and ksud-x86_64-unknown-linux-musl from KernelSU GitHub releases. The --kmi value depends on the current firmware version. The value can be put together by checking the kernel version.

    ./ksud-x86_64-unknown-linux-musl boot-patch -b init_boot.img --magiskboot magiskboot-linux-main/x86_64/magiskboot --kmi android14-6.1
    

• Flash the patched image.

  fastboot flash init_boot ./kernelsu_patched.img
