Build Guide And Info

Supported Devices

- Asus Zenfone Max Pro M1 (X00T, XOOTD, ASUS_X00TD)
- Asus Zenfone Max Pro M2 (X01BD, X01BDA, ASUS_X01BD)

Default Defconfigs

- Asus Zenfone Max Pro M1 -> asus/X00TD_defconfig symlinked to X00TD_defconfig
- Asus Zenfone Max Pro M2 -> asus/X01BD_defconfig symlinked to X01BD_defconfig

Inline Builds(For Including Along With ROM)

  1. Make sure this commit for enabling inline kernel compilation with newer versions of GCC exists in vendor/<rom> of the source as we will be a using GCC 12 unlike deprecated GCC 4.9 synced from AOSP git, else cherry-pick it.
  2. In your device tree, navigate to BoardConfig makefile
- Drop TARGET_KERNEL_CLANG_COMPILE flag
- Enable TARGET_KERNEL_NEW_GCC_COMPILE flag
  1. Now Clone Eva GCC from @mvaisakh's github
  • Trace through dependencies by adding the followong to rom.dependencies
  {
    "remote": "github",
    "repository": "mvaisakh/gcc-arm64",
    "target_path": "prebuilts/gcc/linux-x86/aarch64/aarch64-elf",
    "branch": "gcc-master"
  },
  {
    "remote": "github",
    "repository": "mvaisakh/gcc-arm",
    "target_path": "prebuilts/gcc/linux-x86/arm/arm-eabi",
    "branch": "gcc-master"
  }
  • Else, just add the following to vendorsetup.sh
# Eva GCC
git clone --depth=1 https://github.com/mvaisakh/gcc-arm64.git -b gcc-master prebuilts/gcc/linux-x86/aarch64/aarch64-elf
git clone --depth=1 https://github.com/mvaisakh/gcc-arm.git -b gcc-master prebuilts/gcc/linux-x86/arm/arm-eabi
  1. Incase you run into the following error during the build:-

  • Then your vendor/<rom/> is missing this commit which intentionally points out the 32-bit GCC Path for vdso32 compilation. Cherry-pick it and the build should run without any hassle now.

Standalone Builds

  1. Clone this source into ~/Kernel directory of your workspace.
  2. Run the script as per your device
- For Asus Zenfone Max Pro M1 -> bash X00TD.sh
- For Asus Zenfone Max Pro M2 -> bash X01BD.sh
  1. Once the builds are finished, you will find the recovery flashable zip at ~/Kernel/AnyKernel3 directory of your workspace.

Note

- Incase you face any bugs or errors, then create a github issue innthe repository tab with proper logs.
- Check commit history for more changelogs.
- There wont be any UC, UV variant or messed up display refresh rate variant.
- The released variants are little bit OC'ed to avoid the UI LAGS AND APP OPENING STUTTERS.
- Only Android R and S is supported. For Android Q, roms which are based on LineageOS or Android Q ports like OxygenOS and MIUI only booted.
- Dont blame the kernel if your battery charging speed isnt going up coz its you who cause it to heat already by doing heavy stuffs.
