Nethunter ready kernel source for Nothing Phone 2.

1. Install build dependencies:

sudo apt install make gcc zlib1g zlib1g-dev libssl-dev flex bison build-essential libncurses-dev zstd cpio zip

2. Make shure python is available by python --version. If not, but there is python3:

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1

3. If building under WSL2 check that env PATH doesnt contain any '(' or ')'

env | grep "("
export PATH=$(echo "$PATH" | tr ':' '\n' | grep -v '/mnt/c/' | tr '\n' ':')
env | grep "("

# Dont worry, it will be restored after VM reboot.

3. For kernel source compilation use:

bash build.sh

(Or check release page for kernel .zip.)

4. On building choose (for magisk)

Include KernelSU? If unsure, say N. (Y/N) N
Do you want to do a clean build? If unsure, say N. (Y/N) Y
Do you want to modify .config? If unsure, say N. (Y/N) Y

!!! Important: load nethunter ready config:
Choose <load> and enter build_configs/v1.0.0/config
this config contains basic nethunter setups and drivers for:

    Mediatek:

    SDR:
    - AirSpy
    - HackRF
    - Mirics MSi2500
    - Digital TV support
    - Software defined radio support

Then press <save> and enter .config.
The config will appear at out/.config

Then choose default answers:

    Kernel support for 32-bit EL0 (COMPAT) [Y/n/?] y
      Enable kuser helpers page for 32-bit applications (KUSER_HELPERS) [Y/n/?] y
      Enable vDSO for 32-bit applications (COMPAT_VDSO) [Y/n/?] (NEW) 
        Compile the 32-bit vDSO for Thumb-2 mode (THUMB2_COMPAT_VDSO) [Y/n/?] (NEW) 
    *
    * General architecture-dependent options
    *
    Optimize very unlikely/likely branches (JUMP_LABEL) [Y/n/?] y
      Static key selftest (STATIC_KEYS_SELFTEST) [N/y/?] n
    Enable seccomp to safely execute untrusted bytecode (SECCOMP) [Y/n/?] y
    Stack Protector buffer overflow detection (STACKPROTECTOR) [Y/n/?] y
      Strong Stack Protector (STACKPROTECTOR_STRONG) [Y/n/?] y
    Clang Shadow Call Stack (SHADOW_CALL_STACK) [Y/n/?] y
    Link Time Optimization (LTO)
    > 1. None (LTO_NONE)
      2. Clang Full LTO (EXPERIMENTAL) (LTO_CLANG_FULL) (NEW)
      3. Clang ThinLTO (EXPERIMENTAL) (LTO_CLANG_THIN) (NEW)
    choice[1-3?]: 3
    Use Clang's Control Flow Integrity (CFI) (CFI_CLANG) [N/y/?] (NEW) 
    Enable LLVM's polyhedral loop optimizer (Polly) (LLVM_POLLY) [Y/n/?] y
    Number of bits to use for ASLR of mmap base address (ARCH_MMAP_RND_BITS) [18] 18
    Number of bits to use for ASLR of mmap base address for compatible applications (ARCH_MMAP_RND_COMPAT_BITS) [11] 11
    Provide system calls for 32-bit time_t (COMPAT_32BIT_TIME) [Y/n/?] y
    Use a virtually-mapped stack (VMAP_STACK) [Y/n/?] y
    Use RELR relocation packing (RELR) [Y/n/?] (NEW) 

Also you need to install additional vendor firmware. If dont - you wont be able to do

sudo ifconfig wlan1 up

And got error:
