bricked it?

I’ve tried several different images newly downloaded flashed using both DD and etcher on different PCs not with any success. Different cards too.

At this moment I’ve just tried for the 3rd time. It just doesn’t see the SDcard.

You need use the mrfixit u-boot update script (and img files) to replace the uboot used by Chromium. The uboot packaged with the Chromium builds is forked from an earlier u-boot that put emmc as top priority. If you look on the wiki, I added simple instructions and links to where you can get what you need. I went through this same thing when I first installed CrOS.
