1) get a blank sdcard. 2) write a bootable 'stock' command line only image to it. 3) edit the sdcard images files to either . . . a) load g_serial b) load g_ether and edit /etc/network/interfaces to reflect that both the BBB and the host PC are on the same network. Be aware of the piece of work, know as "connman" c) Just get an ethernet patch cable, and connect directly to the BBB from the host PC. Again, edit /etc/network/interfaces to give *both* a static IP and make sure both are on the same network. d) buy a serial debug cable, and connect via your favorite serial communications app. No idea what is available on Chromium.miniconn probably . . .
Anyhow, once you're in, it should not be too much of a problem to identify the eMMC, and troubleshoot whats going on. Ideally, a serial debug cable would be best, as you get to see whats happening at boot time. However, a decent one can cost around $20, and if you poke around and find one on ebay for ~$2, you're likely going to be waiting for that slow boat to arrive from China . . .
