Flashing the ODROID-U2’s eMMC card without a reader


In the quest for the ideal XBMC set-top box, I’ve bought an ODROID-U2. It’s a small devboard with an Exynos 4412 quad-core Cortex-A9 processor. Pretty much the same chipset as the Samsung Galaxy S3 or the Note 2, which should be more than enough to power XBMC I figured. (Note: At this point it doesn’t run XBMC flawless yet, the menus work great and much faster than on the RPi or the Pivos XIOS DS, 720p content seems to work fine, but 1080 still stutters a bit. However, that’ll supposedly get fixed once XBMC upgrades to multi-core ffmpeg or the video decoder will be implemented)

While the ODROID will boot from MicroSD perfectly, there’s another option called eMMC that is supposedly much faster. If you buy it from them, it’ll include a small converter to microSD so you can flash it with a computer. However, as it turns out this converter is absolute garbage. it’s too big to fit into a regular uSD-SD converter, and even after I filed it down to the appropriate size, it still didn’t work.

So I had this nice box, with Android 4.0 pre-installed, but the one method to upgrade was broken.

Luckily, there’s another way to upgrade by booting to Ubuntu from a microSD card, and access the eMMC module on-board from there. I’ll detail how I did it here.
