===== New updates =====
  * Unsigned "open-gapps" package can be installed now. We removed the sign-check routine like previous Android 5.x Lollipop.
  * Fixed WPA-supplicant issue to show the WiFi module 3 signal strength icon correctly. [[https://forum.odroid.com/viewtopic.php?f=137&t=24752&start=250#p186251|Forum Thread]]
  * Added a few requested USB-Multitouch VID/PID. [[http://forum.odroid.com/viewtopic.php?f=51&t=15495|Forum Thread]]
<code>
/* NEC HDMI capacitive Screen */
#define USB_VENDOR_ID_NEC_1926	0x1926
#define USB_DEVICE_ID_V652_TM	0x036A
</code>

=== Kodi settings =====
  * Kodi 16 is crashing at the end of every video. Uncheck 'Allow hardware acceleration - amcodec' option to solve this issue.\\
  * Kodi 17 has no that issue. It always uses the MediaCodec HW acceleration.\\

==== Self Installation ====
You can install the release to your MicroSD or eMMC with the tool **dd** in Linux or **Win32DiskImager** in Windows. Please refer [[http://odroid.com/dokuwiki/doku.php?id=en:odroid_flashing_tools#using_win32diskimager|this]] for more detail.
<WRAP center round important 80%>
We've reported that some of users can not watch Android logo on their TV while installing even though installation is proceeded. So please wait for 5~10 minutes since power on and red and blue LED is on. If blue led is started blinking then installation is proceeding, ODROID-C2 will reboot when finished.

==== Upgrade Installation ====
This Marshmallow release doesn't support the update/upgrade from Lollipop.\\
You must install the self-installation image.
