Notes for the ODROID-VU7

If you use the low resolution screen like the ODROID-VU7, you need to edit the lcd_density value manually to show the navigation bar properly.
Change “ro.sf.lcd_density=160” to “ro.sf.lcd_density=120” in build.prop file.

$ su
# mount -o rw,remount /
# vi /system/build.prop
# reboot

The USB host VBUS is enabled in the Kernel boot process, the touch screen doesn't work with the USB host.
So we need to fix this issue.

Notes for KODI 4K Video

Known issue

Update Instruction

Self Installation

You can install the release to your MicroSD or eMMC with the tool dd in Linux or Win32DiskImager in Windows. Please refer this for more detail.

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 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.

  • Update server setting
    • You can set your own update server and path where you upload your custom update package. Ordinary users does not need to run this and change the detail, it is already set with Hardkernel's official download server for ODROID-C1/C2.
  • Check online update
    • This will start to check latest update from Hardkernel's official download server and start to download and install if new version is discovered. Your ODROID-C1/C2 device must be connected through the network.
  • Package install from storage
    • This will help you to install the official upgrade package downloaded manually or custom update package. You can store a update file to external storage and select it to install.

Fastboot Update

If you have USB-Serial kit, you can enter to Fastboot mode when you execute the command fastboot on U-boot command line.
