I followed the instructions on wiping the eMMC here. I noticed that the when I first started, the Zero didn’t show as “Amlogic, Inc. GX-CHIP” in lsusb. It only did that when I plugged it in while pressing the USB boot button. It’s now showing that way any time I plug it in and doesn’t seem to boot into any operating system. Am I just doing something wrong or is this stuck in USB boot?

You can also write images directly to eMMC:
