(create these folders)

8. open twrp_a12s.mk and
8.1. delete the 3 lines below # Inherit from those products, Most specific first.
replace those 3 lines with this
$(call inherit-product, $(SRC_TARGET_DIR)/product/aosp_base.mk)

TW_NO_SCREEN_TIMEOUT := true
TW_NO_SCREEN_BLANK := true
#TW_SCREEN_BLANK_ON_BOOT := true
TW_DEVICE_VERSION := 1_physwizz

To save space
-----------------------
if not u have to compress kernel image or reduce the size of kernel
BOARD_KERNEL_IMAGE_NAME := Image.gz
TARGET_PREBUILT_KERNEL := $(DEVICE_PATH)/prebuilt/Image.gz

# compress ramdisk
BOARD_RAMDISK_USE_LZMA := true
LZMA_RAMDISK_TARGETS := recovery

# To save more space
BOARD_HAS_NO_REAL_SDCARD := true

Using AIK to unpack and repack can also reduce size
