Well, that sounds like the right one, but could you post the model number from the underside of the device in full please? For instance, mine starts off with "CB5-571".

I've also uploaded a copy of mine to https://johnlewis.ie/auron_me.bin if that helps - I used it to build a ROM yesterday (and used me_cleaner), and it works a treat as far as I can tell.

Ok sure. Its an acer c910. The image I downloaded from google is coreboot-Google_Auron_yuna.6301.59.8.bin.

I got it by running the crosfirmware.sh script in utils/chromos/ included with coreboot.
