Fastboot: md5 is not defined

[Ryan Toronto]

Hello,

It looks like there's an error when running in Fastboot. The md5 shim throws an error that md5 is not defined on line 7. This creates an infinite loop and crashes the fastboot server.

There was an error running your app in fastboot. More info about the error:
