It appears my eMMC card may be dead. I've plugged into a series of different card readers without success in getting the device recognised. Addy, are you selling spare parts anywhere?
The 8GB replacement eMMC is available direct from Hardkernel at http://www.hardkernel.com/main/products/prdt_info.php?g_code=G145627455789
Many thanks, Addy. Ordered one with the adapter. Time to get this unit back up and running with Unlimited.
