This product is NOT your best option if you do not have technical expertise. Since we do not have the resources to provide technical assistance on your purchase, Odroid forums can be a wonderful resource for you. The ONLY images guaranteed to work are those from the manufacturer, Hardkernel. They provide them free of charge on their website. Any other images are considered "experimental". Also, make sure the media selection switch is in the proper position( ie. emmc or sdcard). If you are using the SD, it must be flashed BEFORE being inserted into ODROID. If the OS is not already on the SD card, the unit will not boot at all.
