Rooting

• Enable OEM unlocking from Android Developer Settings.

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

• 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.

  GitHub - spike0en/nothing_archive: This project indexes, preserves, and generates unmodified stock OTA images, full firmware, and OTA update links for Nothing and CMF devices, sourced directly from official OEM servers. 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.

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

• Flash the patched image.

  fastboot flash init_boot ./patched_init_boot.img

• On KernelSU, go to settings and press uninstall. Choose restore images. After process is complete, do not reboot.
