Getting it to boot is barely even a first step.
If the author especially liked the camera of that phone, it was probably because of the custom app that interfaced to the sensor.
Getting good photography on a linux phone has been one of the enduring problems. Akin to overcoming custom graphics drivers for early linux SoC development.
Like the other (currently top ranked) comment, I highly recommend the furiphone as the current peak of linux phone development.
