Or if you run execute reboot fastboot from Android shell command line, your ODROID-C1 will reboot and get into fastboot mode immediately. You can check if your ODROID-C1 is attached via USB with the command fastboot devices in your desktop.

$ sudo fastboot flash bootloader u-boot.bin
$ sudo fastboot flash dtb meson8b_odroidc.dtb

You can checkout Android source tree, please refer this page for more detail. Please note, Android source tree is uploading and would be completed in 1-2 days.

$ mkdir odroid-c1
$ cd odroid-c1
$ repo init -u https://github.com/hardkernel/android.git -b s805_4.4.2_master
$ repo sync
$ repo start s805_4.4.2_master --all

$ git clone --depth 1 https://github.com/codewalkerster/android_packages_apps_Utility.git -b s805_4.4.2_dev_master

This is the reference boot.ini to customize the boot configuration instead of default. You can just download it and copy into VFAT partition of your MicroSD/eMMC, it will be affected on next boot immediately. Not like Hardkernel's Ubuntu release, this boot.ini does not require uImage and meson8b_odroidc.dtd. This will read such files from the booting card directly.
