Following the procedure bperrybap detailed, so does anything show up on the "guesser" sketch then?

I just checked mine, and with only power and not the SDA SCL connected i get the top row with just squares, i know you took a picture but it didn't show the full trace between the pins on the arduino and the i2c on the lcd, is it possible those two cables are backwards?  A4 to SDA and A5 to scl

The i2cscanner and "guesser" scripts are finding the I2C address and activating the backlight.
