+Loki
+by Dan Rosenberg (@djrbliss)
+=============================
+
+Loki is a set of tools for creating and flashing custom kernels and recoveries
+on the AT&T and Verizon branded Samsung Galaxy S4, the Samsung Galaxy Stellar,
+and various locked LG devices. For an explanation of how the exploit works,
+please see the technical blog post at:
+
+http://blog.azimuthsecurity.com/2013/05/exploiting-samsung-galaxy-s4-secure-boot.html
+
+Devices must be rooted in order to flash custom kernels and recoveries.
+
+loki_tool:
+[patch] option is primarily intended for developers to create custom
+kernels and recoveries. It's designed to take a specific aboot image and an
+unmodified boot or recovery image, and it generates an output image in a new
+file format, ".lok". The resulting .lok image is specifically tailored for the
+device build it was created with, and can be flashed directly to the recovery
+or boot partition on the target device.
+
+[flash] option can be used to flash a .lok image to an actual device.
+It will verify that the provided .lok image is safe to flash for a given target
+and then perform the flashing if validation is successful. It is also possible
+to simply use "dd" to flash a .lok image directly to the boot or recovery partition,
+but using [flash] option is recommended in order to validate that the .lok matches
+the target device.
+
+
+=============
+Sample usage
+=============
+
+First, a developer must pull the aboot image from a target device:
+
+
+dan@pc:~$ adb shell
+shell@android:/ $ su
+shell@android:/ # dd if=/dev/block/platform/msm_sdcc.1/by-name/aboot of=/data/local/tmp/aboot.img
+shell@android:/ # chmod 644 /data/local/tmp/aboot.img
+shell@android:/ # exit
+shell@android:/ $ exit
+dan@pc:~$ adb pull /data/local/tmp/aboot.img
+3293 KB/s (2097152 bytes in 0.621s)
+
+
+Next, a .lok image can be prepared using loki_tool [patch]:
+
+
+dan@pc:~$ loki_tool patch
+Usage: ./loki_tool [patch] [boot|recovery] [aboot.img] [in.img] [out.lok]
+dan@pc:~$ loki_tool patch recovery aboot.img cwm.img cwm.lok
+[+] Detected target AT&T build JDQ39.I337UCUAMDB or JDQ39.I337UCUAMDL
+[+] Output file written to cwm.lok
+
+
+Finally, the .lok image can be flashed using loki_tool [flash]:
+
+
+dan@pc:~$ adb push cwm.lok /data/local/tmp
+dan@pc:~$ adb push loki_tool /data/local/tmp
+dan@pc:~$ adb shell
+shell@android:/ $ su
+shell@android:/ # chmod 755 /data/local/tmp/loki_tool
+shell@android:/ # /data/local/tmp/loki_tool
+Usage: /data/local/tmp/loki_tool [flash] [boot|recovery] [in.lok]
+shell@android:/ # /data/local/tmp/loki_tool flash recovery /data/local/tmp/cwm.lok
+[+] Loki validation passed, flashing image.
