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.
We have been 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 minutes since power on and red and blue LED is on. If blue led is started blinking then installation is proceeding, ODROID-C1 will reboot when finished.
==== Upgrade Installation ====
Since Android release 2.0, we provide you update package which can upgrade your device without rewrite your SD card or eMMC. This package can be downloaded and upgrade on ODROID Utility.
