I believe you can use the builds from http://www.espruino.com/binaries/travis/master/ and update them like you would a Pixl: http://www.espruino.com/Pixl.js#firmware-updates
I can't remember if the bootloader displays anything on the LCD - it may not.
I haven't tested one in a while but it should be fine :)
Magic! I'll give it a go tonight and report back! Cheers!
