A semi-update: I learned from the tow-boot documentation that the Pinephone will not automatically load from an SD card unless you hold the volume button down while holding the power button. When I did this, I was able to boot from the installer SD. I'll leave this thread open in case someone has a specific solution to the issue of Mobian not booting. For my purposes, it was enough to re-install.
