How to build TWRP Recovery

1. You should be able to build CWM Recovery
   
   [GUIDE] Build CWM recovery​
2. Download TWRP as ZIP from github
   
3. Replace ~/android/cm9/bootable/recovery with TWRP
   
4. Modify ~/android/cm9/device/samsung/ariesve/config/init.recovery.rc
   

   on init
        export LD_LIBRARY_PATH .:/sbin // add this line

5. Modify ~/android/cm9/device/samsung/ariesveBoardConfig.mk
   add to the end of file next to recovery stuff :
   

   #TWRP
   TARGET_RECOVERY_PIXEL_FORMAT := "RGBX_8888"
   DEVICE_RESOLUTION := 480x800
   TW_INTERNAL_STORAGE_PATH := "/sdcard"
   TW_INTERNAL_STORAGE_MOUNT_POINT := "sdcard"
   TW_EXTERNAL_STORAGE_PATH := "/external_sd"
   TW_EXTERNAL_STORAGE_MOUNT_POINT := "external_sd"
   TW_DEFAULT_EXTERNAL_STORAGE := true
   TW_FLASH_FROM_STORAGE := true	  	
   TW_HAS_DOWNLOAD_MODE := true
   TW_USE_MODEL_HARDWARE_ID_FOR_DEVICE_ID := true
   TW_MAX_BRIGHTNESS := 255
   TW_BRIGHTNESS_PATH := /sys/devices/platform/msm_fb.196609/leds/lcd-backlight/brightness
   # End TWRP

   More flags for twrp can be found on the original thread by Dees_Troy http://forum.xda-developers.com/showthread.php?t=1943625
   
   
6. Prepare device specific code
   

   $ cd ~/android/[COLOR="Red"]cm9[/COLOR]/
   $ . build/envsetup.sh
   $ lunch //choose -> cm_ariesve-userdebug

7. Compile recovery
   

   make clobber && make -j[COLOR="Red"]#[/COLOR] recoveryimage  //[COLOR="Red"]#[/COLOR] CPU-Cores+1

Get latest kernel message after crash /proc/last_kmsg

[15:33] <+helicopter88> buffo1987, TARGET_PREBUILT_RECOVERY_KERNEL := specifies a kernel to be used during the building of recovery
[15:33] <@Dees_Troy> basically if you want recovery to be built with a different kernel than the boot image then you would use that ^
[15:34] <buffo1987> What could be the benefit?
[15:34] <buffo1987> stability?
[15:34] <@Dees_Troy> maybe
